Facets of Framing: Systematic Approach to an Undertheorized Area of Research on Mass Media Effects Abstract: The paper systematizes the fragmentized research on framing in mass media effects research so far. It conceptually defines the concept by proposing a four-cell typology of framing research looking at media frames and individual frames and at frames as independent and dependent variables. Previous studies are categorized and examined on the basis of this typology and postulates for future research in the field are developed. Facets of Framing Page I. Framing - An Undertheorized Field According to Schulz (1984:206) the formulation of the agenda-setting hypothesis by Cohen (1962) and McCombs and Shaw (1972)[1] is more a speculative idea than a theory in the conventional sense. For Brosius (1994:270) this is one of the reasons why the empirical results in this field are so heterogeneous. A similar theoretical and empirical inaccuracy or at least vagueness characterizes the concept of framing in the field of media effects research. This can be demonstrated on two levels: The first level is looking at the concept itself and at how it is defined. Entman (1993:51) talks about framing as a "kind of a scattered conceptualization". For him, neither the theoretical framework nor the empirical studies have sufficiently explicated or operationalized the concept so far. Brosius and Eps (1993:516) go even further. For them the concept of framing is nothing but a metaphor which is defined relatively vague. On a second level a lack of precision or clarity can be shown by comparing framing to other closely related but different concepts. It seems to be a problem here that in some of the early studies framing has been operationalized in combination with other concepts like agenda setting or priming (Iyengar and Kinder, 1987; Iyengar and Simon, 1993). Maybe as a result later studies referred to these concepts without differentiating at all (Popkin, 1994:84-88) or only inadequately (Staab, 1991:4). What is necessary therefore, is not an additional, different approach to framing analysis, but rather a systematic overview over the phenomenon itself and the studies in the field so far. This paper provides that kind of overview. It does this in three steps: In a first part the theoretical premises underlying the concept are clarified. This includes two steps: First, I look at framing in the larger context of media effects research,[2] and second, I clarify its theoretical premises. In a third part I conceptually redefine framing by developing a typology which classifies the potential applications of framing theory in mass media effects research in respect to the kind of frames under study and to the operationalization of frames as independent or dependent variable. On the basis of this typology previous studies on framing are evaluated. The intention here is not to provide an exhaustive overview of existing operationalizations, but rather to classify the most important approaches. On the basis of this classification the last part of the paper shows deficits of previous studies and relevant areas for future research on framing in mass media effects research. II. Clarification of the Concept In order to give a systematic overview of the different possible approaches to framing, it is necessary to both internally and externally define the concept. An external definition, i.e. the differentiation of framing from other closely related or preceding paradigms in media effects research, examines framing analysis in the larger historical context of the research on media effects. An internal way of defining framing tries to develop a pattern and to identify the basic theoretical premises all conceptualizations of framing have in common. II.1. New look at Effects: Framing as Construction of Social Reality "The entire study of mass communication", as McQuail (1994:327) writes, "is based on the premise that the media have significant effects". This diagnosis, however, must be understood as only temporary result of a scholarly discussion that has been characterized by significant changes in paradigms over the past decades.[3] According to McQuail, the history of research on media effects can be divided into four stages: The first stage from the turn of the century to the late thirties was dominated by the experience with strategic propaganda during World War I which led to a growing fear of the influence of media messages on attitudes. The second stage until the late sixties revised the paradigm of strong media effects. Personal influence was considered to be the main influence on attitude change. Klapper (1960) sums up the findings: Campaigns do not influence people, the major effect is reinforcement of existing attitudes. Even for those, wo actually do change their mind, the effects are minimal. The third stage from the beginning of the seventies is dominated by the search for new strong media effects (Noelle-Neumann, 1973 and 1979:136). The focus of research shifted from attitude changes as in the Columbia studies to more cognitive effects of mass media. The fourth and present stage starts in the early 80s and is characterized by a "social constructivism". The description of media and recipients in this stage combine elements of both strong and limited effects of mass media. On the one hand mass media have a strong impact by constructing social reality, as McQuail (1994:331) argues, i.e. "by framing images of reality [...] in a predictable and patterned way". On the other hand media effects are limited by an interaction between mass media and recipients: "Media discourse is part of the process by which individuals construct meaning, and public opinion is part of the process by which journalists [...] develop and crystallize meaning in public discourse". (Gamson and Modigliani, 1989:2; also Brosius, 1991:285). In respect to methodology this fourth stage is characterized by two aspects: First, television as an object of research on mass media effects plays an important role. Schulz argues that there are two reasons for that development: on the one hand the wide accessibility and the non-selective use of television (Schulz, 1982:63), on the other hand the way television constructs "social formations and history itself [...] in fiction as well as in news" (McQuail, 1994:331; also Noelle-Neumann, 1979a:165; Schulz, 1982:63). Second, media effects research in this fourth stage has reached a level of "methodological prosperity" (Schulz, 1982:65). The postulate for a combination of experimental and survey designs in media effects research as formulated by Hovland (1959:14) is expanded by an additional emphasis on content analysis and panel data (Noelle-Neumann, 1979a:182). The framing approach has to be interpreted against the background of this "social constructivism" for two reasons: First, McQuail (1994:332) explicitly refers to "the various formulations of frame and schema theory" as theoretical developments of this fourth stage of media effects research. Second, Iyengar et al. (1982:848) see their research on priming and framing, i.e. on the new effects of media in the tradition of Lippmann (1922:3-32) as research on social constructivism. Gamson (1992a:67) explicitly refers to framing when he points to a lack of theories providing "the interplay between two levels - between individuals who operate actively in the construction of meaning and socio-cultural processes that offer meanings that are frequently contested". II.2. Theoretical Premises: Framing and Attribution Theory Framing theory can be seen in two traditions. According to Brosius (1994:269 Footnote 3) these two traditions or approaches can be labeled psychological and sociological approach. The psychological approach is based on Kahneman and Tversky's (1972, 1979, and 1984) and Quattrone and Tversky's (1988) "prospect theory" on the nature of subjective probability and judgement. The underlying assumption is "that human rationality is bounded by limitations on memory and computational abilities. Furthermore [...] decision making is often inconsistent with the maxims of rationality" (Quattrone and Tversky, 1988:720). Kahneman and Tversky showed in experimental settings that the evaluation of prospects, i.e. of the expected outcomes of a certain action and the decision for one of two or more alternative actions can be influenced by the way the situation of decision making is described. These descriptions are called "frames" (1984:343). The findings of the experimental studies, as Kahneman and Tversky (1979:288) argue, can also be applied to more general societal settings. Ansolabehere and Iyengar (1993:323-326) for example point to the implications of framing for voting behavior, especially in respect to errors voters might make in assessing the expected value of alternative political decisions. They talk about these phenomena as "information-processing biases, the most relevant of which is framing". Edelman takes this argument a step further into the system of mass media effects. The perception of reality by the individual is for him to a large degree dependent on the way mass media for example describe this reality: "The social world is [...] a kaleidoscope of potential realities, any of which can be readily evoked by altering the way in which observations are framed and categorized" (Edelman, 1993:232). The sociological approach is based on two different theoretical premises: Heider's (1930, 1959, 1978) and Heider and Simmel's (1944) work on attribution theory on the one hand, and Goffman's (1974) theory on frame analysis on the other hand. Heider assumes that human beings can not understand the world in all its complexity (1930:373). Therefore the individual tries to make inferences from the large number of sensory informations to the underlying causal relationships. (1978:28).[4] Heider defined attribution as the link between an observed behavior and a person who is considered to be responsible for this action (1978:22). In his later works he expanded this definition on attribution to environmental factors, i.e. an observed behavior can be attributed to both personal and societal or environmental factors (1959:82).[5] Although Goffman does not explicitly refer to Heider's findings his work has to be understood in the tradition of Heider's theoretical premises on attribution of responsibility. Goffman assumes that we all actively classify and interpret our life experiences to make sense of them. The individual's reaction to sensory information and as a result his actions are therefore dependent on certain frames or schemes of interpretation. These frames can be differentiated into two classes, natural and societal frames.[6] Natural frames help to interpret actions, whose origin lies in the non-intentional physical world. Human factors have no influence. Social frames on the other hand help "to locate, perceive, identify, and label" (Goffman, 1974:21) actions and events which are a result of intentional human action. III. Concept Explication - Media versus Individual Frames An application of these psychological and sociological theories for the field of mass media research has to consider frames as schemata for both presenting and comprehending news. According to Gitlin (1980:7) frames, "largely unspoken and unacknowledged, organize the world both for journalists who report it and, in some important degree, for us who rely on their reports". III.1. Conceptual Definitions The two different concepts of framing and frames which have developed from the theoretical premises outlined can be labeled media frames and individual frames. An application of the psychological approach in the field of media effects research looks at framing in terms of media frames. The question is how attitudes, opinions, or the support for alternative decisions is dependent on the way an issue is framed by the mass media. In the sociological approach the individual frame is of particular interest. The question is which independent variables influence the frames or schemas by which individuals judge their social environment. This terminological and conceptual distinction follows Kinder and Sanders (1990:74). They suggest that frames serve both as "internal structures of the mind", which is equivalent to our definition of individual frames, and "devices embedded in political discourse", which follows our definition of media frames. Entman (1991:7) suggests an equivalent differentiation into individual frames as "information-processing schemata" of individuals on the one hand, and "attributes of the news itself" on the other hand. An exhaustive concept explication of framing must take into account both kinds of frames. III.1.1. Media Frames For Gamson and Modigliani (1987:143, also Gamson, 1992:3) media frames are conceptually defined as "a central organizing idea or story line that provides meaning to an unfolding strip of events [...]. The frame suggests what the controversy is about, the essence of the issue". Tuchman offers a similar definition for media frames. For her media or news frames are necessary to turn meaningless and nonrecognizable happenings into a discernible event. "The news frame organizes everyday reality and the news frame is part and parcel of everyday reality [...], [it] is an essential feature of news" (Tuchman, 1978:193). This concept of media framing can include the intent of the sender, but the motives can also be unconscious ones (Gamson, 1989:158). Entman (1993:52) offers a more detailed explanation of how media frames actually offer schemas for interpretation. For him essential factors are selection and salience: "To frame is to select some aspects of a perceived reality and make them more salient in a communicating text, in such a way as to promote a particular problem definition, causal interpretation, moral evaluation, and/or treatment recommendation". More specific, media frames can be used in four different ways: they can, first, define problems, second, diagnose causes, third, make moral judgements, and fourth, suggest remedies. How events and news are framed and presented in the mass media can thus systematically affect how recipients of the news come to understand these events (Price, Tewksbury, and Powers, 1995:4). III.1.2. Individual Frames The concept of individual framing refers to cognitive schemata of individuals that help to interpret political events (Pan and Kosicki, 1993:56). Frames or schemata are for Entman therefore defined as "mentally stored clusters of ideas that guide individuals' processing of information (1993:53). Two frames of reference can be used to interpret and process information: global and long-term political views on the one hand, and short-term issue-related frames of reference on the other hand. Global political views are a result of certain personal characteristics of individuals[7] and have a rather limited influence on the perception and interpretation of political problems (Kinder, 1983:414). The short-term issue-related frames of reference, however, have a significant influence on perceiving and processing information. Graber (1984:22) talks about "organized knowledge about situations and individuals that has been abstracted from prior experiences. It is used for processing new information and retrieving stored information". Her findings are consistent with the theoretical premises outlined above. By far "the most common way to interpret news stories is to view them from the perspective of likely causes of observed effects" (Graber, 1984:155). Iyengar and Simon come to similar results. For them individuals tend "to simplify political issues by reducing them to questions of responsibility" (Iyengar and Simon, 1993:879). III.1.3. A Typology of Framing When trying to systematize the studies on framing in mass media effects research beginning with Iyengar's seminal work (1987, 1989, 1991) we have to systematically take into account the role that media and individual frames can play in political information processing and interpretation. Theoretically both media and individual frames can be examined as independent or dependent variable. We can therefore develop a four-cell typology which classifies all empirical studies on framing in dependence of the way they conceptually define framing. ____________________________________________________________________________ _ _ _ _ _ _ Frame as _ Frame as _ _ _ Dependent Variable _ Independent Variable _ _ _ _ _ _ _ _ _ ____________________________________________________________________________ _ _ _ - Pan and Kosicki (1993) _ _ _ _ - Entman (1993) _ _ Media _ _ _ _ Frames _ _ _ _ _ _ _ _ _ _ _ ____________________________________________________________________________ _ _ - Iyengar (1987, 1989, _ - Graber (1984) _ _ _ and 1991) _ _ _ Individual _ - Gamson (1992) _ _ _ Frames _ - Price, Tewksbury, _ _ _ _ and Powers (1995) _ _ _ _ _ _ ____________________________________________________________________________ Table 1: Typology of Frames Ideally empirical studies on framing in the field of mass media effects should conceptually and operationally define both concepts, media and individual framing, as independent and dependent variable in order to fully examine the construction of social reality. The questions that have to be asked for the four cells of the typology are: 1) What factors influence the way journalists or other societal groups frame certain issues? 2) What kinds of media frames influence the audience's perception of certain issues? 3) Which factors influence the establishment of individual frames of reference, or are individual frames simply replications of media frames? 4) How do individual frames influence perception of issues, opinions, or even actions of individuals? III.2. Operationalizations I now look at the way previous studies have operationalized media and individual frames. I use the four-cell typology to classify theses studies, to identify deficits in respect to concept explication and operationalization, and to show relevant areas for future study. III.2.1 Operationalization of Media Frames as Dependent Variable The top-left cell of the typology has not yet been adequately empirically operationalized. Van Dijk (1985) raises the question, "why, for instance, [...] news items [have] the kind of thematic or schematic structures we want to study?" (1985:70). He suspects that the way news is framed in mass media is a result of social and professional routines of journalists. Gamson and Modigliani (1987:168) assume that the formation of frames can be explained by an interaction of journalists' norms and practices and of the influence of interest groups. For Edelman (1993:232) the choice of frames "is typically driven by ideology and prejudice". Bennett (1993) and Edelman (1977, 1993) offer a qualitative approach to this aspect of framing. For Edelman the framing of issues by societal groups is a result of intentional considerations. He provides some evidence in form of an exploratory qualitative analysis of the news coverage on the Gulf War of 1991. "Authorities and pressure groups categorize beliefs in a way that marshals support and opposition to their interests" (1977:51). By using the means of mass media they construct opinions and reality by using their societal influence to establish certain frames of reference. These frames can differ significantly from the objective reality. Bennett (1993) talks about category mistakes which are established via mass media. "The mass media become powerful agents for publicizing these mistakes by featuring the words of the public officials who claim to represent the vast majority of the people" (Bennett, 1993:114). III.2.2. Operationalizations of Media Frames as Independent Variables Conceptualizations of framing developed by Pan and Kosicki (1991) and Entman (1993) consider media frames to be the independent variable. Their main focus of interest is the question, which kinds of media frames can be identified. They do not examine, however, how attitudes, opinions, or even individual frames of the public change in dependence of these media frames. Pan and Kosicki (1993) describe the structure of news discourse in general and potential framing devices in particular. They conceptually define media frames to be "tools for newsmakers to use in composing or constructing news as well as psychological stimuli for audiences to process" (1993:59). With a newspaper article on an anti-abortion rally held in Wichita, Kansas as an example they present four types of structural dimensions of news which influence the formation of frames: 1) Syntactic Structures: This dimension refers to patterns in the arrangements of words or phrases. 2) Script Structures: This feature of frames includes two aspects, a general newsworthiness of an event on the one hand, and the intention to communicate news and events to the audience which transcends their limited sensory experiences. 3) Thematic Structure: Journalists tend to impose a causal theme to their news stories, either in form of explicit causal statements or by linking observations to direct quote of a source. 4) Rhetorical Structures: This dimension of media framing refers the "the stylistic choices made by journalists in relation to their intended effects" (Pan and Kosicki, 1993:61). Entman (1993) examines the coverage on the downing of a Korean and an Iranian airplane. Frames are for him conceptually defined as independent variable, i.e. as "attributes of the news itself" (1993:7), which influence both political decision making and public opinion. He content analyzes all articles on the issue in the New York Times and the Washington Post, two issues of both TIME and Newsweek, and the CBS Evening News during this two week period. He identifies five traits of media texts that set a certain frame of reference which have a critical impact on information processing: 1) importance judgements, 2) agency, i.e. the answer to the question, who did it, 3) identification with potential victims, 4) categorization, i.e. the choice of labels for the incidents, and 5) generalizations to a broader national context. Entman (1993:22-23) interprets political decision making and poll results as empirical evidence of the impact of news frames he measures in the content analysis. For him public announcements of both Congress and the House of Representatives and the fact that Congress took concrete steps against international terrorism can be considered as evidence for the impact of framing of news messages on public opinion. He also presents poll results as further evidence for this impact. Although both assumptions seems to be quite reasonable, the inferences he makes are not supported by the data he presents. A content analysis of a sample of print and TV media combined with non-longitudinal secondary survey data does not allow for the inference, that "the [...] story convinced the public" (Entman, 1993:23). III.2.3. Individual Frames as Independent Variable In a panel study of 10 interviews between 1976 and 1977 among about 170 registered voters in Evanston, Illinois, Graber (1984) examined the schemata or individual frames that people use to process political information. These independent variables turned out to be highly stable over time. "Once established, schemas resist disconfirmation" (Graber, 1984:149). With open-ended questions she tried to tap the way people perceived the importance and nature of issues and asked them to report them in their own way. The analysis of the answers to the open-ended questions led to three major conclusions (Graber (1984:173): 1) Most people have a rather broad range of individual frames that are likely to crop up in news stories. 2) Over nine different issues Graber could identify five subdimensions of individual frames which influence the perception and interpretation of news: first, a cause-and-effect dimension, second, a personal dimension, third, an institutional dimension, fourth, a human interest and empathy dimension, and fifth, a cultural dimension (1984:188-189). 3) The individual frames or "individual schemas reported [...] reveal a good deal of shared stereotypical thinking by all [...] panelists". III.2.4. Individual Frames as Dependent Variable The studies on individual frames as dependent variable (Iyengar, 1987, 1989, 1991; Gamson, 1992; Price, Tewksbury, and Powers, 1995) all operationalize a relationship between media framing as independent and individual frames as dependent variable. As the emphasis in all of these approaches is on individual information-processing, however, they are in this paper classified as studies on individual frames as dependent variable. Iyengar (1987, 1989, 1991) content analyzed all newscasts of the television networks ABC, CBS, and NBC. This analysis showed that networks frame newscasts either in episodic or thematic terms.[8] Episodic newscasts depict public issues in form of concrete instances or specific events, thematic newscasts report on a more abstract level in form of general outcomes. Iyengar's analyses also showed "that the networks rely extensively on episodic framing" (1993:370). Between 1985 and 1987 Iyengar conducted nine experiments in a pretest-posttest-design.[9] He exposed his subjects to an experimental stimulus in form of a newscast which contained a number of stories. One of the stories classified as either episodic or thematic in the content analysis was inserted into the newscast. The experimental stimulus was varied in a 2x5 design. On the one hand the inserted story was framed either thematically or episodically, on the other hand five issues were tested: crime, terrorism, poverty, unemployment, and racial inequality. According to results on open-ended questions in the posttest questionnaire two dimensions of attribution of responsibility can be differentiated: causal and treatment responsibility (1987:818-819, and 1991:28). Both dimensions can be further divided into punitive, individualistic or personal, and societal or systemic attributions of responsibility. Gamson (1992) operationalized individual frames in a more qualitative approach. He examines the relationship between ideas and symbols used in public discourse on the individual frames "that people are able to construct on many issues" (1992:6). In 37 focus group discussions among 188 participants he confronted groups of five people with four different issues: the Arab-Israeli conflict, troubled industry, affirmative action, and nuclear power. The independent variables were so-called critical discourse moments in form of cartoons and newsstories on the four issues which were handed out to the participants in the focus groups (1992:26). In order not to artificially set a frame of reference the facilitators in the single groups used a standardized script when introducing the issues. Gamson could identify three ideal types of formation of frames on the group level: cultural, personal, and integrated. A cultural approach to develop a common individual frame is defined as a group discussion which relies exclusively on media discourse and popular wisdom. A personal approach relies only on experimental knowledge and popular wisdom in framing the issue, but does not integrate media discourse to support it. Integrated discussions use all three elements, media discourse, popular knowledge, and experimental knowledge, to form individual frames in group discussion (Gamson, 1992:129). The most elaborate approach to individual frames as dependent variable is offered by Price, Tewksbury, and Price (1995). For them previous studies have exclusively focused on politically relevant outcomes of framing and not "examined directly the more immediate influence of story frames on readers' cognitive responses" (Price, Tewksbury, and Powers, 1995:5). Therefore both media frames as independent variable and individual frames as dependent variable are operationalized. In an experimental setting Price, Tewksbury, and Powers examine the influence of certain characteristics of media coverage on "the knowledge activation process, in particular effect of news frames on the applicability of ideas and feelings" (Price, Tewksbury, and Powers, 1995:5). 135 undergraduate students were asked to read news articles about possible cuts in state funding to the university that were experimentally prepared to manipulate various news frames. Three manipulated settings, each of them framed in a particular way, and one control group were established (Price, Tewksbury, and Powers, 1995:12-13): 1) Conflict Frame: This article described the conflict between opposing interest groups. 2) Human Interest Frame: This story covered the retirement of a state budget director, who was tired of struggling to provide equitable funding for all Michigan universities. 3) Consequence Frame: Here potential financial consequences for all students were mentioned. In a posttest questionnaire the students were asked "to write down all thoughts and feelings you had while reading the preceding article, including those thoughts that are not necessarily relevant to the article" (Price, Tewksbury, and Powers, 1995:13). A content analysis of the open-ended question showed that issue frames of news stories had a significant influence on the respondents' cognitive responses. The most interesting finding was a phenomenon, that Price, Tewksbury, and Powers (1995:23) call "a kind of 'hydraulic' pattern, with thoughts of one kind, stimulated by the frame, driving out other possible responses". These findings correspond with Iyengar's (1990) assumption that information that can be most easily retrieved from memory tends to dominate judgements, opinions and decisions (Iyengar, 1990:1).[10] IV. Deficits and Outlook On the basis of both the conceptual framework provided by the four-cell typology developed above and of the operationalizations and empirical findings presented, three problematic areas of framing in the field of media effects research can be identified: First, studies focus on single aspects of framing instead of a relationship between media and individual frames. Second, media frames are treated as short-term phenomena which can be tested in experimental studies. And third, combinations of methods are not or only insufficiently applied for studies on mass media effects. IV.1. The Four-Cell typology as Model for Future Research The presentation of operationalizations and empirical results has shown, that the fractured paradigm that Entman (1993:51) talks about is not only problematic in respect to conceptualization of framing but also in respect to its operationalization. Future studies therefore have to agree on a systematic approach on the research on framing. The four-type model developed offers a first step in this direction. In order to fully explain and describe the influences and effects of framing in the field of mass media effects research, all four cells have to be part of an exhaustive concept explication on framing. IV.2. Long-Term Versus Short-Term Effects Looking at previous studies and findings on framing also shows that so far framing has been considered to be a short-term effect of mass media. According to Graber (1984), however, "change of established schemas is troublesome, especially when schemas are based on personal experiences or on judgements accepted from highly trusted sources" (Graber, 1984:142). This means, that frames of reference seem to be undynamic variables which are influenced by factors other than issue-related media coverage. Graber (1984) talks about schemas or frames as a result of socialization processes. "Schema acquisition bears the imprint of the particular culture in which learning takes place" (Graber, 1984:148). IV.3. Combination of Methods as Main Objective of Framing Research As a result of the first two aspects mentioned, the need to cover all aspects of framing and to include a long-term notion of individual frames in the concept, the third postulate for future research has to be a combination of methods. Two aspects seem to be especially important here, a reevaluation of television news as main focus of research on the one hand, and an emphasis on content analysis and panel-survey designs as additional methods for examining framing effects on the other hand. IV.3.1. Television as Main Focus of Framing Research The first aspect, the focus on television news in framing research, seems to be appropriate when television is considered to be a medium which can both produce and change opinions (Noelle-Neumann, 1980:125). This potential of television must be understood, however, as only necessary condition for an influence on recipients. Especially in respect to short-term concepts of mass media effects the sufficient condition "actual exposure to news" has to be fulfilled. Therefore, experimental designs as suggested by Iyengar (e.g. 1991) seem to be inappropriate. Guo and Moy (1995) for example falsified in a cross-medium comparison between television and newspaper Iyengar and Kinder's (1987:1) assumptions of a dominant influence of television on the political perceptions of individuals in two respects: On the one hand they showed that the influence of television international and national news on knowledge and political participation could be to a large degree explained by newspaper reading as antecedent variable (Guo and Moy, 1995:13 and 24). On the other hand they assume, that "the goal of television is mainly entertainment" (Guo and Moy, 1995:3). An experimental setting in which subjects are exposed exclusively to television news in an artificial reception situation drastically reduces the external validity of the findings. Hovland summarizes this phenomenon with the term "captive audience" (Hovland, 1959:8).[11] IV.3.2. Experiment, Survey, and Panel For the second aspect, the postulate for a combination of methods in media effects research we have to look at two aspects: a general applicability of the experiment as a method for exploring mass media effects on the one hand, and the relevance of a combination of methods for the field in general. The laboratory experiment is important for the social sciences in general and mass media effects in particular for two reasons (Schulz, (1970:135). First, the large numbers of independent and intervening variables and the interactions between them in the process of mass communication research lead to difficulties in analyzing these relationships. An exploration of the effects of mass media is therefore only possible, as Hovland (1959:15) writes, by reduction of the number of independent variables in the laboratory experiment. Second, experiments are the only method that allows to actually prove a causal relationship between variables (Schulz, 1970:76). These causal relationships can usually be shown on a high level of statistical significance, i.e. a high internal validity. For Kerlinger (1986:368) experiments are therefore of great importance for measuring short-term influences of stimuli on attitudes, knowledge and behavior of recipients. A high level of internal validity does not necessarily allow for a generalization of the results, however (Brosius, 1991:293). Making inferences from experimental settings of framing on general social settings, i.e. on media effects is therefore possible only to a very limited extent. IV.3.3. Relevant Aspects for Future Research For future research two postulates can be formulated. The first postulate addresses the four-cell table introduced. Future research has to systematically concentrate on the empty cell which looks at media frames as dependent variable. Research designs appropriate for filling this cell with high quality findings could follow equivalent research designs from the field of agenda-setting research (for an overview see Staab, 1990; Scheufele, 1993). Kepplinger (1991, 1992), and Lang, Engel Lang, Kepplinger, and Ehmig (1993) look at the influence of historical events on the professional and political attitudes of German journalists in print and broadcast media. In order to show influences of these attitudes on the media agenda Kepplinger, Brosius, Staab, and Linke (1989) proposed a model that assumes that journalists' criteria for selecting news are directly influenced by their political attitudes in general and their point of view on certain issues in particular. Similar models could be developed for framing research. The second postulate is closely related to the first one. In order to show the processes that influence the framing of media content through journalists' attitudes or opinions a combination of multi-method approaches with longitudinal data is a necessary condition. Journalists' attitudes have to be assessed in surveys and the results have to be compared at various points of time to results from content analyses of media content. Noelle-Neumann's postulate (1979a:181) is therefore still valid. The experiment is no longer an appropriate means of measuring all levels of mass media effects, as the most important independent variables can not be controlled in experimental settings. For her (Noelle-Neumann, 1979:133) Hovland's (1959:14) postulate for a combination of experimental and survey data has to be extended to content analysis and panel data to adequately test mass media effects in general and framing effects on a levels in particular.

[1] It is important to notice, however, that the idea itself is not new and has been mentioned by other authors before Cohen's study (Schulz, 1984:206 Footnote 1). [2] Another area of framing research, which is only indirectly concerned with effects of mass media and can therefore not be covered here, is the field of social movements. Snow, Burke Rochford, Jr., Worden, and Benford (1986) and Snow and Benford (1988 and 1992) look at the importance of master frames and collective action frames for the study of cycles of protest. Klanderman and Oegema's (1987), Klanderman's (1988 and 1992), and Entman and Rojeki's (1993) work is focused rather on the potential of master frames invented by social movements to influence the motivation for individuals to support these movements and to form consensus. Entman and Rojecki (1993:156) for example suggest "seven evaluative dimensions of news messages that are likely to affect a movement's ability to garner public support". Gerhards and Rucht (1992:582) finally try to synthesize the previous findings into a consistent model. They offer a differentiation into three types of framing: First, diagnostic framing, which means identifying a problem and the attribution of blame and causality, second, prognostic framing, which specifies, what needs to be done, and third, motivational framing, i.e. the "call to arms for engaging in ameliorative or corrective action" (Snow and Benford, 1988:199). [3] McQuail's book itself is an indicator for this changing paradigms. While in the second edition (McQuail, 1987:251) he talks about the agreement "that there are effects from the media", the third edition refers in the same context to "significant effects" of mass media (McQuail, 1994:327). [4] Heider also provided experimental evidence for his assumptions. A vast majority of subjects who were shown movies with abstract movements of geometrical shapes interpreted these movements as actions of human beings with a certain underlying motivation (Heider and Simmel, 1944:245). [5] Heider talks about "effective personal force and effective environmental force" (1959:22). [6] This difference between natural and societal frames is equivalent to Heider's differentiation into personal and environmental attributions. [7] Kinder (1983:401) and Kinder and Sears (1985:671) could identify six personal characteristics which influence global political views of individuals: personality, self-interest, leadership, group identification, values, and inferences from history. [8] As a clear distinction between thematic and episodic frames was impossible news stories were "classified on the predominant frame" (1991:18). [9] The experiments were conducted with 40 to 244 subjects. Neither in the original studies (1987, 1989) nor in the summarized results (1991) Iyengar does provide information on the exact date of the experiments or the precise number of subjects per experiment, however. [10] For the theoretical background on both Iyengar's (1991) and Price, Tewksbury, and Power's (1995) rather speculative explanations see Collins and Loftus (1975) and Tulving and Watkins (1975). Tulving and Watkins assume that by processing information individuals develop certain "memory traces" (1975:261). Collins and Loftus use the term "activation tags" for the same phenomenon: "When a concept is primed, activation tags are spread [...]. When another concept is subsequently presented, it has to make contact with one of the tags left earlier and find an intersection" (Collins and Loftus, 1975:409). [11] In respect to captive audiences two more aspects are of importance: On the one hand, Noelle- Neumann (1979:133) assumes that only a cumulative effect, i.e. a combination of consonant messages from various media has significant effects on the audience. On the other hand Noelle-Neumann (1991:229) showed that individuals' perception of reality and therefore the construction of frames is influenced by two sources of perception: direct perception of their environment and mediated perception of reality. The previous research designs on framing have taken neither of the two aspects into account.
