This work provides a conceptual introduction to mediation, moderation, and conditional process analysis in psychological research. We discuss the concepts of direct effect, indirect effect, total effect, conditional effect, conditional direct effect, conditional indirect effect, and the index of moderated mediation index, while providing our perspective on certain analysis and interpretation confusions that sometimes arise in practice in this journal and elsewhere, such as reliance on the causal steps approach and the Sobel test in mediation analysis, misinterpreting the regression coefficients in a model that includes a product of variables, and subgroups mediation analysis rather than conditional process analysis when exploring whether an indirect effect depends on a moderator. We also illustrate how to conduct various analyses that are the focus of this paper with the freely-available PROCESS procedure available for SPSS, SAS, and R, using data from an experimental investigation on the effectiveness of personal or testimonial narrative messages in improving intergroup attitudes.

This article presents three studies examining the importance of identification with characters in research on media entertainment. In Study 1 it was found that identification with characters was associated with spectators' degree of enjoyment of feature films of different genres. Study 2 showed that identification with characters predicts the affective impact of a dramatic film and, also, it was associated with greater cognitive elaboration and a more complex reflexive process during the viewing of the dramatic film. In Study 3 it was observed that identification with characters predicted the incidental impact of a full length fictional film on attitudes and beliefs. These results support the centrality of the construct of identification with characters in narrative persuasion research.

This study aimed to contribute to the understanding of the mechanisms explaining the so-called framing effect. Experimental research (N = 355) was carried out with a 2 × 2 between-subjects factor design in which the news frame and group cues were manipulated in a news story on the consequences of the increase in immigration in Spain, and their impact on cognitive, attitudinal, and emotional variables was assessed. The results show that the type of news frame stressed in the report exerted significant cognitive, attitudinal, and emotional effects. It was also found that the emotional impact aroused by the news frame was conditioned by the incidental presence of information regarding the national or geographic origin of the immigrants in question. These results are consistent with the hypotheses posed and partially support the argument that the framing effect is a process governed by heuristic processing.
