Minority influence and social categorization

In this article, a theoretical distinction is proposed between representative outgroup minorities (representative of a minority category in the society, e.g. gays) and dissident outgroup minorities (defined as a minority subgroup within a larger outgroup category). Two studies are reported comparing the social influence of dissident outgroup minorities with that of ingroup minorities (belonging to the subject's own social category). It was predicted that a position advocated by a dissident outgroup minority would be more readily accepted than that of an ingroup minority, but that the ingroup minority would be more likely to elicit the generation of new, alternative solutions. A first experiment in which subjects were either exposed to an ingroup minority, an outgroup minority, or no influence source confirmed these predictions. In a second experiment, subjects were either exposed to a majority or to a minority source either belonging to the subject's own social category or to the outgroup. The results indicate that the position of an ingroup majority was readily accepted whereas the otherwise identical message of an outgroup majority was rejected; neither ingroup nor outgroup majority stimulated the development of alternative proposals. Again, in line with Nemeth' (1986a) theory, the position of an ingroup minority was rejected but stimulated the generation of new, alternative proposals. The differential role of social category membership in minority and majority influence and the applicability of Nemeth' (1986a) theory to the attitude change area are discussed.     

IMPLICIT MEMORY IN AMNESIC PATIENTS:

Abstract— Amnesic patients generally exhibit spared priming effects on implicit memory tasks despite poor explicit memory In a previous study, we demonstrated normal auditory priming in amnesic patients on an identification-in-noise test in which the magnitude of priming is independent of whether the speaker's voice is the same or different at study and test In the present experiment, we examined auditory priming on a filter identification test in which the magnitude of priming in control subjects is higher when the speaker's voice is the same at study and test than when it is different Amnesic patients, by contrast, failed to exhibit more priming in a same-voice condition than in a different-voice condition Voice-specific priming may depend on a memory system that is impaired in amnesia     

Effect of autonomy support and dialogic learning on school children’s physical activity and sport

This study applies an intervention based on autonomy support through dialogic learning to examine effects on motivation and the promotion of physical activity and sport involvement during schoolchildren’s leisure time. One hundred and two primary school students, aged 11–13 years, participated (M = 10.93, SD = 0.75). The sample was divided into two groups: an experimental group (49 students) and a control group (53 students). A quasi-experimental study was conducted in physical education classes over the course of 9 months. Assessments of autonomy support from teachers, family, and peers; basic psychological needs; self-determined motivation in physical education and during leisure time; planned behavior variables; physical activity intention; and estimated and actual physical exercise behavior time were included in the model. Following the intervention, the results revealed that greater autonomy support by the teacher, the family and peers, satisfaction of the basic psychological needs, self-determined motivation during physical education class and during free time, greater perceived control, favorable attitude and intention to engage in physical activity contributed to the explanation of student physical activity involvement. These results suggest that when students receive extensive social support from diverse social agents that essential precursors to physical activity are strengthened and contribute to increased motivation and actual physical activity involvement. Efforts to promote effective communications with students and other pedagogical efforts, such as providing dialogic learning opportunities, should be considered in order to strengthen physical activity motivation and involvement in students.     

Measuring task-switching ability in the Implicit Association Test

Recently, the role of method-specific variance in the Implicit Association Test (IAT) was examined (McFarland & Crouch, 2002; Mierke & Klauer, 2003). This article presents a new content-unspecific control task for the assessment of task-switching ability within the IAT methodology. Study 1 showed that this task exhibited good internal consistency and stability. Studies 2-4 examined method-specific variance in the IAT and showed that the control task is significantly associated with conventionally scored IAT effects of the IAT-Anxiety. Using the D measures proposed by Greenwald, Nosek, and Banaji (2003), the amount of method-specific variance in the IAT-Anxiety could be reduced. Possible directions for future research are outlined.
