On mediation

The mediation-nonmediation dichotomy proposed by the Kendlers (Psychological Review, 1962, 69, 1–16) and subscribed to by Cole and Medin (Journal of Experimental Child Psychology, 1973, 15, 352–355) is reviewed and critiqued. It is proposed that the appropriate question for research is how children mediate, not when they mediate.     

Where is the facilitation of media violence: The effects of nonexposure and placement of anger arousal

The present study examined the conditions under which media violence would “facilitate” aggression in angered individuals. It was noted that previous research has lacked support for facilitation due to improper control groups. It was predicted, based upon evidence that aggressive and neutral films are capable of both arousing a subject and shifting his attention away from previous anger instigation (attentional shift), that only under a condition where an aggressive film is viewed prior to anger arousal will increased aggression occur if compared to a no-film control. It was found that when subjects were angered prior to film exposure, netural films reduced aggression, with aggressive films not differing from a no-film control. Under subsequent anger arousal, however, there was a facilitation for aggressive film exposure. The implication of this, and other recent media violence studies, for past and future research in the area of media violence and aggression is discussed.     

Recall of sex-role appropriate and inappropriate models in children's songs

The function of sex of model and sex-role appropriateness of models' behavior in facilitating children's recall of song characters and content was explored. Fifty-eight boys and girls, aged 6 1/2, listened to two songs in one of three treatment conditions. The songs had male-dominant/female-subordinant, female-dominant/male-subordinant, or neutral-dominant/neutral-subordinant lyrics. As expected, children attended selectively to same-sex characters, recalling more when the same-sex character was dominant. Boys reported liking males more than females, while girls had no sexual preference. Surprisingly, both boys and girls more frequently reported that they wanted to be like the subordinant characters than like the dominant characters.     

THE USE OF STIMULUS CONTROL OVER LITTERING IN A NATURAL SETTING

A conventional litter receptacle (55-gallon drum) and a specially designed receptacle consisting of a 55-gallon drum adorned with a plywood “hat” were alternated in two areas of a football stadium over a period of four games. A frequency count of several types of litter articles showed that more than twice as many items were deposited within the experimental container than the conventional one (an average of 52.5 and 21.5 items per game, respectively). The weight of litter deposited within each container showed a similar relationship. An average of 0.65 kg of litter per game were deposited within the conventional receptacle compared with an average of 1.3 kg per game for the experimental receptacle.     

Memory confusions for real and imagined completions of symmetrical visual patterns

In Experiment 1, subject ratings indicated that it was easier to imaginally complete half of a symmetrical form when the form was symmetrical about the vertical axis than when the form was rotated so that it was symmetrical about the horizontal axis. In Experiment 2, new subjects saw these same forms, some presented as wholes and some presented as halves. Compared with controls, subjects who were instructed to imagine the vertically symmetrical half forms as complete had more difficulty remembering which forms had been presented as wholes and which had been presented as halves. Imagery and control groups did not differ in ability to discriminate half from whole horizontally symmetrical forms. The results are consistent with predictions from Johnson and Raye’s (1981) reality monitoring model that discriminating memories of imagined and perceived events should be a function of the amount of cognitive operations included in the memory.     

The consequences for memory of imagining in another person’s voice

Subjects listened to and imagined words and then attempted to discriminate words they had heard from words they had imagined. Discrimination was better when subjects imagined themselves saying the words (Experiments 1 and 2) than when subjects imagined the words in the speaker’s voice. Subjects also had more difficulty discriminating imagined from perceived words when they imagined in the speaker’s voice than when they imagined words in a voice other than their own or the speaker’s (Experiment 1). The results are consistent with the idea that reality monitoring is affected by the degree of similarity in sensory characteristics of memories derived from perception and from imagination (Johnson & Raye, 1981).
