Expectation of outgroup behaviour: can you trust the outgroup?

Outgroups are usually viewed with suspicion and expected to discriminate against the ingroup. The present study demonstrated that ingroup members attributed past discriminatory behaviour committed by individuals of unknown group membership more to outgroup members than to either ingroup members or members of a neutral group. In contrast, past egalitarian behaviour was attributed less to outgroup members than to members of a neutral group. Ingroup members also expected more discrimination from a future outgroup allocator than from a future neutral group allocator. Finally, the study showed that ingroup members' own behaviour in allocating money became more biased in favour of ingroup members vis-á-vis outgroup members when the future allocator was from an outgroup rather than from a neutral group and when they had witnessed the discriminatory behaviour of an allocator in the past.     

Maternal depressive history, teen 5HTTLPR genotype, and the processing of emotional faces: Exploring mechanisms of risk

Variations in the serotonin transporter gene (5HTTLPR) and biased processing of face-emotion displays both have been implicated in the transmission of depression risk, but little is known about developmental influences on these relationships. Within a community sample of adolescents, we examine whether 5HTTLPR genotype moderates the link between maternal depressive history and errors in face-emotion labeling. When controlling for current levels of depression and anxiety among youth, a two-way interaction between maternal depressive history and 5HTTLPR genotype was detected. Specifically, adolescents whose mothers reported a depressive history and who had a low expressing genotype made more errors in classifying emotional faces when compared with adolescents with an intermediate or high expressing genotype, with or without maternal depression history. These findings highlight the complex manner in which maternal depression and genetic risk may interact to predict individual differences in social information processing.     

Microcomputer requirements in the operational Navy

The microcomputer seems destined to play an ever increasing role in today’s operational Navy. It promises solutions to problems ranging from inventory control to tactical decision making. With that promise, however, comes an inevitable array of new problems and questions to be solved. The Navy constantly must evaluate systems on the basis of the systems’ ability to produce immediate gains. Design characteristics most important in the choice of systems include application software, equipment reliability and availability, software maintainability, ease of use, and integrated approach. The Navy’s demand for more properly human-engineered systems far exceeds that of industry in general. Until designers can deliver such systems, the influx of microcomputers into the operational Navy will continue to be thought of as an unnecessary proliferation.     

The behavioral impact of an advertising campaign to promote safety belt use.

Safety belt use was observed at one restaurant during McDonald''s "Make It Click" promotional campaign. Following baseline, the program was monitored without intervention. During the final 2 weeks of the campaign an incentive strategy was added providing a large soft drink contingent on safety belt use. Safety belt use did not change from baseline levels before the incentive phase. The rate of belt use increased under contingent reward and declined during follow-up. The effects of a verbal prompt could not be assessed because of the almost nonexistent use of the "Make It Click" stickers throughout the study.     

Support for the Death Penalty and Rehabilitation: Question Order or Communication Effect?1

Response‐effects research has shown that survey questions shape and channel public opinion. Our study examines the degree to which the variance in people's cognitions about and attitudes toward crime policy proposals is a methodological artifact and the degree to which it represents media effects. Four different forms of a survey were used to manipulate the order of the proposal (death penalty vs. rehabilitation) and criterion (cognition vs. attitude). Results show that experimental manipulations affected cognitions or attitudes only for the death penalty. Respondents who were asked the cognition measure first showed a high level of consistency between the net valence of their arguments and their attitudes. Respondents who were asked their attitudes first reported relatively more affective arguments, a phenomenon that we label affective priming. Exposure and attention to specific media content influenced cognitions and attitudes differentially.     

The influence of action perception on object recognition: a developmental study

Two experiments explored the existence and the development of relations between action representations and object representations. A priming paradigm was used in which participants viewed an action pantomime followed by the picture of a tool, the tool being either associated or unassociated with the preceding action. Overall, we observed that the perception of an action pantomime can facilitate the recognition of a corresponding tool. Experiment 1 was based on a naming task and was conducted with 9- to 12-year-old children and a group of young adults. While substantial priming effects were obtained for all age groups, they were especially important for the youngest participants. Smaller priming effects were obtained in Experiment 2, using a categorization task and conducted on 5- to 11-year-old children and young adults, but again the results suggest that these action priming effects diminish with increasing age. Implications of these results for the organization and development of conceptual knowledge are discussed.
