Gender role stereotyping in Australian radio commercials

Most previous research into gender role stereotypes in the mass media has concentrated on television or print. Only one content analysis (Furnham & Schofield, 1986) has examined radio content, finding patterns of bias in British radio commercials consistent with, though less marked than, those in television commercials. The present study sought to determine whether similar patterns obtain in another Western country’s radio commercials collected approximately a decade later. Over 100 Australian radio ads were content analyzed, and results very similar to those of the earlier study were obtained. The findings are discussed in terms of their implications for studies of gender role development and audience reactions to media content. We are grateful to Elyse Frankel and Jason Low for assistance in data coding and checking, and to two anonymous reviewers for constructive commentaries on an earlier version.     

Hippocampal synaptic plasticity during instrumental learning

present research examined the role of hippocampal NMDA-dependent synaptic potentiation on appetitive instrumental conditioning under a continuous reinforcement schedule. In the first experiment, low (.025 mg.kg) or moderate (.05 mg/kg) dosages of the NMDA receptor antagonist, MK801, failed to increase the number of training days required to reach acquisition criterion; number of training days required to reach criterion for extinction were also unaffected. In the second experiment, a higher dosage (.10 mg/kg) of MK801 or induction of long-term potentiation failed to alter the number of responses occurring during acquisition. These data suggest that hippocampal synaptic potentiation does not play a prominent role in instrumental learning with simple contingency conditions. It is suggested that hippocampal LTP reflects a perceptual process that contributes differentially to spatial cognition, classical and instrumental conditioning.     

THE CREDIBLE SHRINKING ROOM:

Abstract— Becoming a proficient symbol user is a universal developmental last in the first years of life, but delecting and mentally representing symbolic relations can be quite challenging for young children To test the extent to which symbolic reasoning per se is problematic, we compared the performance of 2-year-olds in symbolic and nonsymbolic versions of a search task. The children had to use their knowledge of the location of a toy hidden in a room to draw an inference about where to find a miniature toy in a scale model of the room (and vice versa) Children in the nonsymbolic condition believed a shrinking machine had caused the room to become the model They were much more successful than children in the symbolic condition, for whom the model served as a symbol of the room The symbol understanding and use.     

A PRELIMINARY COMPARISON OF REINFORCER ASSESSMENT METHODS FOR CHILDREN WITH ATTENTION DEFICIT HYPERACTIVITY DISORDER

We evaluated the relative treatment utility of a verbal forced-choice questionnaire, child nomination, and direct observation for identifying the most potent reinforcers for children with attention deficit hyperactivity disorder. Results demonstrated that all three methods were more likely to disagree than to agree, that a forced-choice format may enhance verbal reinforcer assessment, and that further development and evaluation of verbal reinforcer-assessment methods are needed.     

The third person effect: Social distance and perceived media bias

Two studies were conducted to determine the conditions under which the third person effect (Davison, 1983) operates. It was hypothesized that the effect would be accentuated as target groups of others became more remote from the self. A second objective was to determine whether the effect operates in the absence of overtly persuasive intent in the media. Television programmes concerned with moral themes were employed as stimuli. The results further support Davison's claim that overestimation of media effects is greater when people imagine the responses of others whom they do not know than those of familar individuals. The results also indicate that the third person effect does operate in the absence of perceived persuasive intent, but is accentuated when bias is perceived by viewers.     

Romantic partners and body image disturbance: Further evidence for the role of perceived—actual disparities

In this study, female and male college dyads (primarily Caucasian) involved in a “romantic relationship” used schematic figures to rate their conceptions of body size on a variety of rating protocols, including actual self, ideal self, ideal opposite gender, perceived partner's ideal opposite gender, perceived partner's rating of self, and rating of partner's body size. Based on the reflected-appraisal literature and previous body image research on perceived—actual disparities in body size ratings, five discrepancy indices were created and related to dispositional levels of body image disturbance, eating dysfunction, and general psychological function (self-esteem, depression). The results clearly indicated gender differences in the particular predictor associated with all measures of disturbance. For females, the discrepancy between the Self rating and the Perceived Partner's Ideal Other Gender rating accounted for almost all of the variance associated with clinical indices of disturbance. For males, the discrepancy between the Self rating and the Actual Partner's Ideal Other Gender rating was the only important predictor to emerge in regression analyses. The findings are interpreted in light of recent research on actual/perceived differences in body size ratings.     

An investigation of the relationship between self-efficacy and the communication effectiveness of product manual formats

Product manuals have been virtually ignored in published research despite their relevance to consumer satisfaction and marketplace safety. This study examines self-efficacy (perceptions of capabilities related to operating a product) and how it influences the effectiveness of and is also influenced by three safety message formats commonly used in product manuals (i.e., 1. safety messages presented in list format at the front of the manual; 2; safety messages presented by semantic similarity interspersed throughout the manual—chunked format, and 3. safety messages presented in a combined format—both list and chunked). As anticipated, pre-exposure self-efficacy was a significant covariate which was found to be positively related to post-exposure self-efficacy and negatively related to information evaluation. Further, controlling for pre-exposure self-efficacy, post-exposure self-efficacy was significantly lower in the combined (list plus chunked) condition. Findings of this research have important implications for the practice of repeating safety warnings and future research in the consumer information domain.Authors are listed in alphabetical order.

Wisdom and abiding interest: Interviews with three noted historians in later life

This article explores the connections between wisdom-related attributes and abiding interest and draws upon material from interviews with three eminent historians in later life. It is proposed that one characteristic of wisdom, namely, the coordination of affective/attaching and cognitive/detaching modes of processing information, is related to abiding interest or the ability to self-regulate attention in a way that promotes lifelong learning. The article (a) reviews pertinent constructs in the literatures on adult development and wisdom; (b) presents selected excerpts from in-depth interviews; and (c) concludes by discussing the developmental implications of the ideas presented.     

Anxious attachment and psychological distress in cardiac rehabilitation patients

This study investigated the relevance of anxious attachment to the differentiation of psychologically distressed and non-psychologically distressed cardiac patients. Attachment is a biologically based behavioral system in which proximity to a special other is sought or maintained to achieve a sense of safety and security. Anxious attachment, as the name denotes, fails to achieve the function of attachment in the sense of individuals having little or no confidence in the availability of their attachment figures. Empirically, three scales (feared loss of the attachment figure, proximity seeking and separation protest) capture the features of anxious attachment as elaborated by Bowlby. These scales were administered to 178 cardiac rehabilitation patients drawn from the cardiac rehabilitation program of the Calgary General Hospital. The results indicate that feared loss and proximity seeking differentiated psychologically distressed from non-psychologically distressed patients. The implications of this finding for the understanding of psychologically distressed cardiac patients are discussed.
