The influence of an audience upon the reactions to filmed violence

In order to examine audience effects when viewing firmed violence, 5 to 6 year old pre-school boys who had been rated as submissive by their teachers watched an aggressive or a neutral movie either alone, accompanied by another submissive classmate, or a dominant one. Subsequent aggression against a frustrating, unknown and unseen boy was delivered via a modified Buss machine, especially adapted for children. Subjects accompanied by a dominant peer were more aggressive than the others but did not react differentially to the movies. Subjects tested alone were more aggressive after the violent film than after the neutral one and the opposite pattern occurred for the boys accompanied by a submissive classmate. These findings stress the importance of the social context when viewing filmed violence. It is suggested that the quality of the audience can have different directional (e.g. fear and aggression) as well as energizing properties. Links with the literature on social facilitation and audience effects are underlined.     

Are you ‘woman enough’ to control your leading cause of death?: an ethnographic content analysis of women’s cardiovascular disease and identities in media narratives

The Heart Truth^® campaign was implemented in the United States by the National Heart, Lung, and Blood Institute in 2002 to increase women’s awareness of heart disease and encourage risk reduction of cardiovascular disease. The present study explored representations of women’s cardiovascular disease, the meanings generated, and the implications for identity construction within one prominent corporate media partner of the campaign. The inaugural 2003 October issue of Glamour magazine was the focus of an ethnographic content analysis. Women’s cardiovascular disease was constructed within an overarching theme of a culture of consumerism, with meanings of cardiovascular disease emerging within two subthemes: (a) the oblivious, unknowledgeable, dependent woman at risk and (b) attaining a particular version of a healthy, feminine woman. Women’s identities were constructed as dependent on experts, purchasing fashion and fitness merchandise, and heteronormative roles for health management. These findings extend health psychology research that has called for more critical explorations of media to extend understandings of disease meanings and the implications for identity and women’s health.     

Culture and the distinctiveness motive: constructing identity in individualistic and collectivistic contexts

The motive to attain a distinctive identity is sometimes thought to be stronger in, or even specific to, those socialized into individualistic cultures. Using data from 4,751 participants in 21 cultural groups (18 nations and 3 regions), we tested this prediction against our alternative view that culture would moderate the ways in which people achieve feelings of distinctiveness, rather than influence the strength of their motivation to do so. We measured the distinctiveness motive using an indirect technique to avoid cultural response biases. Analyses showed that the distinctiveness motive was not weaker-and, if anything, was stronger-in more collectivistic nations. However, individualism-collectivism was found to moderate the ways in which feelings of distinctiveness were constructed: Distinctiveness was associated more closely with difference and separateness in more individualistic cultures and was associated more closely with social position in more collectivistic cultures. Multilevel analysis confirmed that it is the prevailing beliefs and values in an individual's context, rather than the individual's own beliefs and values, that account for these differences.     

Interactive Links Between Theory of Mind,Peer Victimization,and Reactive and Proactive Aggression

This study investigated the relation between theory of mind and reactive and proactive aggression, respectively, as well as the moderating role of peer victimization in this context. The 574 participants were drawn from a longitudinal study of twins. Theory of mind was assessed before school entry, when participants were 5 years old. Reactive and proactive aggression as well as peer victimization were assessed a year later in kindergarten. Results from multilevel regression analyses revealed that low theory of mind was related to a high level of reactive aggression, but only in children who experienced average to high levels of peer victimization. In contrast, a high theory of mind was related to a high level of proactive aggression. Again, this relation was especially pronounced in children who experienced high levels of peer victimization. These findings challenge the social skills deficit view of aggression and provide support for a multidimensional perspective of aggressive behavior.     

Perceived group and personal discrimination: differential effects on personal self‐esteem

In two studies, we investigate the differential influence of perceived group and personal discrimination on self‐esteem in the context of the Rejection–Identification model (Branscombe, Schmitt, & Harvey, 1999 ). We first polled a group of African immigrants and found that whereas personal discrimination was negatively related to personal self‐esteem, group discrimination was positively associated with it. As expected, identification served as a buffer between personal discrimination and self‐esteem. We replicated these effects in a second study using women as our respondents. These results suggest that perceiving group discrimination may be positively related to self‐esteem because people feel less alone in their plight, thereby alleviating the ill‐effects of exclusion. We discuss these results in relation to both the Rejection–Identification model and the discounting hypothesis (Crocker & Major, 1989 ). Copyright © 2006 John Wiley & Sons, Ltd.     

Transfer of inhibition after serial feature negative discrimination training

Three experiments examined the transfer of inhibition in Pavlovian serial feature negative (A+, X→ A−) discriminations in a conditioned suppression situation with rat subjects. Consistent with our previous report (P. C. Holland & J. Lamarre, Learning and Motivation, 15, 219–243), the feature (X) showed little or no ability to inhibit suppression to another conditioned excitor (B) that had been consistently reinforced. Nor was substantial transfer observed to excitors that had been partially reinforced, or conditioned, extinguished, and then reconditioned. However, X readily inhibited suppression to an excitor that had been trained within another serial feature negative discrimination (B+, Y → B−). These latter data are difficult to reconcile with our previous proposal that inhibitors established with serial procedures act on particular conditioned stimulus-unconditioned stimulus associations. We suggest that serial feature negative discriminations endow both the feature (X) and the excitor (A) with special properties.     

Sensory effects on judgments of short time-intervals

Two experiments were conducted to test the effect of nontemporal factors on duration discrimination. In Exp. 1, a forced-choice adaptive procedure with a standard duration of 400 or 800 ms was employed. It was shown that, for both auditory and visual modes, the discrimination is better with empty intervals (a silent period between two brief signals) than with filled intervals (a continuous signal), but only with shorter durations. In a second experiment, where intervals of the same duration range were employed but were presented with a single-stimulus method, discrimination was better with empty than with filled intervals, and this effect applied to both ranges of duration and both sensory modes. In both experiments, discrimination was better in the auditory than in the visual mode. These data are discussed in the context of current models of timing mechanisms.

The functional independence of mands and tacts

This study demonstrates functional independence in the acquisition of mands and tacts. Some subjects first learned to mand the experimenter's placement of objects with the prepositional phrases “On the left” and “On the right.” They were regularly tested for collateral appearance of tacts with these same phrases. Other subjects learned to tact the location of objects with these prepositional phrases and were regularly tested for collateral appearance of mands. All subjects were next trained in the repertoire that had not been trained in the first condition (either tact or mand). After all subjects had learned both to mand and to tact correctly, another assessment of mand-tact independence was undertaken. Mands (tacts) were reversed and testing assessed collateral reversal of tacts (mands). The results demonstrated that tacts and mands, even when incorporating identical response forms, were functionally independent during acquisition. Subsequent modification of one repertoire (by reversal training) produced collateral reversal in three of nine subjects.     

When does it hurt? Intergroup permeability moderates the link between discrimination and self‐esteem

Research shows that personal discrimination and group discrimination have distinct effects on personal self‐esteem. Specifically, whereas personal discrimination negatively impacts self‐esteem, group discrimination increases it. We suggest that this pattern is dependent on the socio‐structural context in which individuals experience discrimination. To test this hypothesis, we manipulate intergroup permeability and examine its impact on the link between personal/group discrimination and personal self‐esteem. Results show that a control condition replicates previous research, that is, a positive association between group discrimination and self‐esteem and a negative association for personal discrimination. The positive association of group discrimination disappeared in a permeable context and reversed when the context was presented as impermeable. Moreover, the deleterious effect of personal discrimination on self‐esteem vanished in impermeable contexts. Results are discussed in light of the literature on stigmatization.

Physical aggression and expressive vocabulary in 19-month-old twins

In the prevention of physical aggression, possible etiological links with language development are rarely taken into account. Indeed, little is known about when language and aggressive behavior become linked during development and which mechanisms are responsible for this association. This study investigated the association between physical aggression and language in late infancy with a genetic design that involved 562 19-month-old twins. A modest but significant correlation (r = -.20) was found between physical aggression and expressive vocabulary. Substantial heritability was found for physical aggression. Quantitative genetic modeling suggests that the correlation between expressive vocabulary and physical aggression cannot be explained by shared etiologies. However, phenotype-to-phenotype models indicate that the covariation can be entirely accounted for by a significant phenotypic path from expressive vocabulary to physical aggression. The implications of these results for early prevention of chronic physical aggression are discussed.
