The Feminist Identity Development Model: Relevant for Young Women Today?

We explored whether the Downing and Roush model of feminist identity development is relevant for young women today. Two-hundred seventeen older and younger feminists and non-feminists were recruited on a college campus and online in the United States. They completed, online, the Feminist Identity Composite and reported whether they would have endorsed items for each stage more strongly in the past. Qualitative data was collected about prior stage experience. Older feminists scored higher in active commitment, and younger feminists scored higher in revelation. Feminist self-identification did not relate to synthesis scores, and young women high in synthesis did not report much prior stage experience. We postulate that synthesis is a starting point for young women, rather than an ending point.     

The interplay of individual differences,norms, and group identification in predicting prejudiced behavior in online video game interactions

Despite the increasing popularity of video games and the diversity of people who play, prejudice remains common in online gaming. In the current study, we use structural equation modeling to test the role of social norms, individual differences, and gamer identification as predictors of how likely someone is to report engaging in prejudiced behavior while playing online video games. We also test the relative importance of these predictors to assess how likely people are to confront prejudice when it occurs in online video games. Participants (N = 384) completed a series of questionnaires to assess their attitudes and perceptions of online gaming norms, as well as to report their own prejudiced and confrontation behavior in video games. We found that both social norms and individual differences are significant predictors of behavior in online gaming. The more normative people report prejudice to be, the more they report making prejudiced comments. Similarly, the more normative confrontation of prejudice is reported to be, the more likely people are to report confronting prejudice. The more people endorsed generally prejudiced attitudes, the more likely they were to report making prejudiced remakes in online gaming and the less likely they were to report confronting prejudiced remarks. These results provide a foundation to inform interventions to reduce prejudice in gaming and indicate that both individual differences and norms are important to consider when designing interventions.

Pharmacological manipulations of brain catecholamines and the aggressive behavior induced by marihuana in REM-sleep-deprived rats

A marihuana extract, apomorphine, and amphetamine provoked in rats previously deprived of REM sleep for 96 hr an upright position with the animals pawing each other as in fighting. Nondeprived rats injected with the drugs did not show this aggressive behavior. The marihuana-treated animals also bit vigorously a rod introduced into the cage, a fact not observed with the apomorphine-treated rats. These data suggest that the marihuana aggressiveness could at least partially be mediated through the brain catecholamines. Haloperidol, chlorpromazine, α-methyl-p-tyrosine, and reserpine decreased the marihuana aggressiveness of the deprived rats. Increase of dopamine concentration by previous treatment with Dopa potentiated aggressiveness. Blockade of norepinephrine synthesis by FLA-63 was ineffective in reducing marihuana aggressiveness in the REM-sleep-deprived rats. Actually, in these animals aggressiveness appreared even without the marihuana injection. Phenoxybenzamine partially blocked marihuana aggressiveness but also severely depressed the rats. However, 20 mg/kg alone succeeded in provoking aggressiveness in the deprived rats. It is suggested that in rats with neural excitability heightened by previous REM-sleep deprivation dopamine facilitates aggressive behavior, an effect inhibited by porepinephrine. This hypothesis would imply that marihuana induces aggressiveness in REM-sleep-deprived rats by inhibiting, through an as yet unknown mechanism, the central norepinephrine system.     

Comparing responses of four ungulate species to playbacks of baboon alarm calls

A growing body of evidence suggests that a wide range of animals can recognize and respond appropriately to calls produced by other species. Social learning has been implicated as a possible mechanism by which heterospecific call recognition might develop. To examine whether familiarity and/or shared vulnerability with the calling species might influence the ability of sympatric species to distinguish heterospecific alarm calls, we tested whether four ungulate species (impala: Aepyceros melampus; tsessebe: Damaliscus lunatus; zebra: Equus burchelli; wildebeest: Connochaetes taurinus) could distinguish baboon (Papio hamadryas ursinus) alarm calls from other loud baboon calls produced during intra-specific aggressive interactions (‘contest’ calls). Overall, subjects’ responses were stronger following playback of alarm calls than contest calls. Of the species tested, impala showed the strongest responses and the greatest difference in composite response scores, suggesting they were best able to differentiate call types. Compared with the other ungulate species, impala are the most frequent associates of baboons. Moreover, like baboons, they are susceptible to both lion and leopard attacks, whereas leopards rarely take the larger ungulates. Although it seems possible that high rates of association and/or shared vulnerability may influence impala’s greater ability to distinguish among baboon call types, our results point to a stronger influence of familiarity. Ours is the first study to compare such abilities among several community members with variable natural histories, and we discuss future experiments that would more systematically examine development of these skills in young ungulates.
