Homegrown stereotypes are generalizations that groups develop about their own typical characteristics. They are a distinct class of in-group stereotypes in the contexts and processes that give rise to them, as well as in their consequences for individual group members. The authors develop the concept of homegrown stereotypes and locate the origins of these stereotypes in self-presentation processes. They discuss the accuracy of these stereotypes and consider their similarities to and differences from a number of related phenomena. An examination of homegrown stereotypes highlights the importance of taking into account the impact of in-group, as well as intergroup, dynamics on the production of stereotypes. 相似文献

Individuals with autism have been noted to have restricted interests and repetitive behavior such as nonfunctional manipulation of objects. In this study, we used an observational conditioning procedure to switch the preference of items for four individuals diagnosed with autism who are considered lower functioning. The procedure consisted of the participant observing an adult playing with toys that were initially non‐preferred by the participant in a functional and engaging manner. For two participants, results were similar to the findings by Leaf; one participant required additional conditioning procedures, and we were unable to switch the preference for the other participant.

The relationship between luminance (i.e., the photometric intensity of light) and its perception (i.e., sensations of lightness or brightness) has long been a puzzle. In addition to the mystery of why these perceptual qualities do not scale with luminance in any simple way, \"illusions\" such as simultaneous brightness contrast, Mach bands, Craik-O'Brien-Cornsweet edge effects, and the Chubb-Sperling-Solomon illusion have all generated much interest but no generally accepted explanation. The authors review evidence that the full range of this perceptual phenomenology can be rationalized in terms of an empirical theory of vision. The implication of these observations is that perceptions of lightness and brightness are generated according to the probability distributions of the possible sources of luminance values in stimuli that are inevitably ambiguous. 相似文献

Qualitative data from an empirical study of adolescent suicide risk were analyzed to examine the screening component built in to a larger protocol. It was determined that a significant number of students were being identified as being in need of follow-up. Although the majority (88.7%) of students screened met criteria for placement in the no indicators (of risk) category, 3.8% evidenced apparent need of follow-up, 4.4% qualified for notable concern, and 3.1% were deemed to be at-risk or in crisis. Several gender and ethnic differences in risk category status are also discussed. The system utilized at the school and examples of the range of interventions utilized are discussed. Evidence for the positive effects of this screening on individual students and the school as a whole are presented. Arguments for the regular use of screening measures in high schools and suggestions for implementation are also given. 相似文献

Mental health disorders continue to plague service members and veterans; thus, new approaches are required to help address such outcomes. The identification of risk and resilience factors for these disorders in specific populations can better inform both treatment and prevention strategies. This study focuses on a unique population of U.S. Army Special Operations personnel to assess how specific avenues of social support and personal morale are related to mental health outcomes. The results indicate that, whereas personal morale and friend support reduce the relationship between combat experiences and posttraumatic stress disorder (PTSD), strong unit support exacerbates the negative effects of combat experiences in relation to PTSD. The study thus shows that although informal social support can lessen postdeployment mental health concerns, military populations with strong internal bonds may be at greater risk of PTSD because the support that they receive from fellow service members may heighten the traumatic impact of combat experiences. 相似文献
