A preferential-looking procedure was used to investigate newborns' responses to square-wave gratings varying in spatial frequency and contrast. A preliminary study confirmed that the gratings used in the experiment were suprathreshold. In the experiment newborns' preference for a grating of 0.1 cycle deg-1 within the peak contrast sensitivity range was examined. Reduction in the contrast of this grating led to a transfer of the preference to a high-contrast grating of the same space-averaged luminance with a spatial frequency outside this range (0.42 cycle deg-1). The findings are discussed with reference to the role of the contrast sensitivity function in pattern preferences of newborns: it is suggested that contrast and spatial frequency interact in determining pattern preferences. 相似文献

Two experiments examined whether exposure to an uncontrollable relationship between an action and its outcome during a nonaversive pretreatment phase would attenuate subsequent ratings of control given to actions emitted by subjects. In Experiment 1, such an interference effect was demonstrated relative to a group that received prior training with a controllable action- outcome relationship, and relative to a group not exposed to any prior relationship. In Experiment 2, these effects were replicated, and interference was also found to occur when learning a maze task. Thus, the effects of helplessness were shown to be quite general, to be produced by a nonaversive induction procedure, and to occur most readily when the current contingency between action and outcome was weakest. 相似文献

Seemingly Harmless Racial Communications Are Not So Harmless: Racial Microaggressions Lead to Suicidal Ideation by Way of Depression Symptoms 下载免费PDF全文

Racial microaggressions, a contemporary form of subtle discrimination that occurs in everyday interactions, are associated with a variety of negative mental health outcomes. Research has not extended the connection between racial microaggressions and negative mental health to include suicide risk. Given the well‐known association between negative mental health outcomes and suicide risk, the current study examined whether racial microaggressions predicted suicidal ideation through depression symptoms among 405 young adults of color. Depression symptoms mediated the relationship between racial microaggressions and suicidal ideation. This is the first study to associate racial microaggressions to suicide risk. Societal and clinical implications are discussed. 相似文献

ABSTRACTThis study explores the gendered body hair removal norm and the meanings of male body hair by examining young people’s sense-making around male body hair removal. The novel technique of story completion was used to collect data from 102 psychology undergraduates. They were presented with a story “stem” featuring a young man (David) deciding to start body hair removal and asked to complete the stem. David was most often portrayed as a young heterosexual man who was excessively hairy, in the “wrong” places, was often subject to teasing and bullying, and was concerned about his diminished sexual capital. Hair removal did not always end “happily ever after” for David. While in some stories he “got the girl,” he was punished for his vanity and foolishness in others. These different endings arguably reflect currently ambivalent meanings around male body hair depilation. The production of a hairless, or less hairy, male body is both desirable and a potential threat to masculinity. The data spoke strongly to the power of social norms surrounding body hair practices and suggest that story completion provides a useful tool in interrogating the discourses that sustain these norms. 相似文献
