Two experiments demonstrated striking, reversible forgetting effects that occurred even for a list of expletives. The experiments used a procedure based on the classic memory mechanisms of interference and retrieval cuing. Interference reduced recall dramatically, although appropriate cues triggered complete recovery. Distinctive, emotionally charged materials were quite susceptible to the forgetting and recovery effects. Thus, powerful forgetting effects can be obtained when participants have no intentions to forget and the materials involved are distinctive, emotional materials with sexual and violent content. This forgetting is reversible with appropriate cues. The false-memory debate can and must be informed by experimental investigations not only of false memories, but also of blocked and recovered memories. 相似文献

Classroom discussion practices that can lead to reasoned participation by all students are presented and described by the
authors. Their research emphasizes the careful orchestration of talk and tasks in academic learning. Parallels are drawn to
the philosophical work on deliberative discourse and the fundamental goal of equipping all students to participate in academically
productive talk. These practices, termed Accountable TalkSM, emphasize the forms and norms of discourse that support and promote equity and access to rigorous academic learning. They
have been shown to result in academic achievement for diverse populations of students. The authors outline Accountable Talk
as encompassing three broad dimensions: one, accountability to the learning community, in which participants listen to and
build their contributions in response to those of others; two, accountability to accepted standards of reasoning, talk that
emphasizes logical connections and the drawing of reasonable conclusions; and, three, accountability to knowledge, talk that
is based explicitly on facts, written texts, or other public information. With more than fifteen years research into Accountable
Talk applications across a wide range of classrooms and grade levels, the authors detail the challenges and limitations of
contexts in which discourse norms are not shared by all members of the classroom community.

Men's and women's mate preferences impose on each a unique set of adaptive problems that must be solved when judging the desirability of prospective mates. One potentially revealing source of information about an individual's desirability as a romantic partner is contained in the decisions made by same-sex others. The present studies predicted that men's and women's desirability assessments would be affected in opposite ways when target persons were depicted with members of the target's opposite sex. Study 1 (N = 847) documented that women rated men more desirable when shown surrounded by women than when shown alone or with other men (a desirability enhancement effect). In sharp contrast, men rated women less desirable when shown surrounded by men than when shown alone or with women (a desirability diminution effect) . Study 2 (N = 627) demonstrated similar sexually divergent effects for estimates of the desirability of same-sex competitors. 相似文献

Little is known about whether the clinical correlates of hoarding behavior are different in men and women with obsessive-compulsive disorder (OCD). In the current study, we evaluated the association of hoarding with categories of obsessions and compulsions, psychiatric disorders, personality dimensions, and other clinical characteristics separately in 151 men and 358 women with OCD who were examined during the OCD Collaborative Genetics Study. We found that, among men but not women, hoarding was associated with aggressive, sexual, and religious obsessions and checking compulsions. In men, hoarding was associated with generalized anxiety disorder and tics whereas, among women, hoarding was associated with social phobia, post-traumatic stress disorder, body dysmorphic disorder, nail biting, and skin picking. In women but not men, hoarding was associated with schizotypal and dependent personality disorder dimensions, and with low conscientiousness. These findings indicate that specific clinical correlates of hoarding in OCD are different in men and women and may reflect sex-specific differences in the course, expression, and/or etiology of hoarding behavior in OCD. 相似文献

Little is known about the prevalence and correlates of hoarding behavior in the community. We estimated the prevalence and evaluated correlates of hoarding in 742 participants in the Hopkins Epidemiology of Personality Disorder Study. The prevalence of hoarding was nearly 4% (5.3%, weighted) and was greater in older than younger age groups, greater in men than women, and inversely related to household income. Hoarding was associated with alcohol dependence; paranoid, schizotypal, avoidant, and obsessive-compulsive personality disorder traits; insecurity from home break-ins and excessive physical discipline before 16 years of age; and parental psychopathology. These findings suggest that hoarding may be relatively prevalent and that alcohol dependence, personality disorder traits, and specific childhood adversities are associated with hoarding in the community. 相似文献

Forty toddlers aged 20 to 24 months were presented with 32 pairs of images with the auditory stimulus Look followed by the name of the target image (e.g. Look . . . tree) in an intermodal preferential looking (IPL) paradigm. The same series of 16 items was presented first with one image as target and then with the other member of the pair as target. Half the children were given feedback, in the form of movement of the target image at the end of the trial, while the other half were presented with static images. IPL performance was quantified in terms of number of words showing at least 15% increase in proportion of looking time in the post-naming interval. Looking preference for the named item was correlated with parental report of vocabulary, this effect being stronger for those receiving feedback. The correlation with parental report of vocabulary comprehension was .65 for those receiving feedback, but only .37 for those with no feedback. It is concluded that the preferential looking task, which has been widely used in group studies, has the potential to act as a reliable index of comprehension level in individual children, especially when movement feedback is used to maintain attention. 相似文献
