Despite Skinner's (1957) assertion that verbal operants are initially functionally independent, recent studies have suggested that in some cases the acquisition of one verbal operant (e.g., mand) gives rise to the other (e.g., tact) without explicit training. The present study aimed to evaluate the functional independence of mands and tacts during instruction with children with autism. Four boys with autism (3 to 6 years old) were taught to construct two 4‐piece structures. Two participants were taught directly to mand, whereas the other 2 were taught to tact the names of the pieces. The effects of training were evaluated in a multiple probe design across verbal operants and tasks. Three of the 4 participants demonstrated an immediate transfer of control from 1 verbal operant to the other. These results were consistent with previous research with typically developing young children. 相似文献

Sources of individual differences in scientific problem solving were investigated. Participants representing a wide range of experience in geology completed tests of visuospatial ability and geological knowledge, and performed a geological bedrock mapping task, in which they attempted to infer the geological structure of an area in the Tobacco Root Mountains of Montana. A Visuospatial Ability × Geological Knowledge interaction was found, such that visuospatial ability positively predicted mapping performance at low, but not high, levels of geological knowledge. This finding suggests that high levels of domain knowledge may sometimes enable circumvention of performance limitations associated with cognitive abilities. 相似文献

Unlike other forms of positive thinking (e.g., expectations), research finds that positive fantasies (experiencing one's thoughts and mental images about the future positively) predict low effort and little success in several domains. However, for vocational education students of low socioeconomic status and minority ethnicity, for whom the present environment is especially difficult, perhaps it would be appropriate to indulge in positive fantasies that depict the future as bright and easily attained. Three studies show that this is not the case. Positive future fantasies measured early in the program predicted more days absent (Studies 2–3) and lower grades at the end of the program (Studies 1–3), even when adjusting for initial academic competence, expectations of successful achievement, and self‐discipline. Expectations of successful achievement predicted fewer days absent and higher grades only when measured midway through the school year, once participants had experience with their own academic standing (Study 3). Results indicate that positive fantasies, which allow people to indulge in images of a bright future, predict poor achievement even in vocational students immersed in a particularly difficult environment.

The association between attachment dimensions (anxiety and avoidance) can influence measurement creation and statistical analyses. Our goal was to test the assumption that anxiety and avoidance was orthogonal in two popular measures: the ‘Experience in Close Relationships Scale - Revised’ (ECR-R) and the original ‘Experiences in Close Relationships Scale’ (ECR). Our meta-analysis of 242 studies revealed that despite both scales being highly reliable, the anxiety-avoidance correlation was higher for the ECR-R than the ECR. Other variables also moderated the association. Implications include methods of statistical analysis and recommendations for future measurement creation and use. 相似文献

Some research indicates that social exclusion leads to increased emotional- and physical-pain sensitivity, whereas other work indicates that exclusion causes emotional- and physical-pain numbing. This research sought to examine what causes these opposing outcomes. In Study 1, the paradigm used to instantiate social exclusion was found to moderate the social exclusion-physical pain relation: Future-life exclusion led to a numbing of physical pain whereas Cyberball exclusion led to hypersensitivity. Study 2 examined the underlying mechanism, which was hypothesized to be the severity of the "social injury." Participants were subjected to either the standard future-life exclusion manipulation (purported to be a highly severe social injury) or a newly created, less-severe version. Supporting our hypothesis, the standard (highly severe) future-life exclusion led to physical-pain numbing, whereas the less-severe future-life exclusion resulted in hypersensitivity. Implications of these results for understanding the exclusion-pain relation and other exclusion effects are discussed. 相似文献

The role of interpersonal components of perfectionism in suicide outcomes among youth was assessed and the Perfectionism Social Disconnection Model (PSDM) was tested by determining whether the links between socially prescribed perfectionism (SPP) and perfectionistic self-presentation (PSP) and suicide outcomes are mediated by experiences of social disconnection, as indicated by social hopelessness and being bullied. PSP, trait perfectionism, suicide outcomes, and experiences of being bullied and social hopelessness were measured in 152 psychiatric outpatient children and adolescents. Correlational tests confirmed that PSP and SPP were associated with suicide outcomes and these interpersonal perfectionism components were associated significantly with bullying and social hopelessness. Support was also obtained for the PSDM. The relationship between the PSP facets, particularly nondisplay of imperfections, and suicide outcomes were mediated by being bullied. Additionally, the relationship between all interpersonal components of perfectionism and suicide risk was mediated by social hopelessness. Theoretical and clinical implications of interpersonal components of perfectionism and social disconnection in suicide outcomes for youth are discussed. 相似文献

A female physician who was serving as a first-year medicine resident in Manhattan in September 2001 writes this paper. It
details her experience of signing up for military service as a result of the September 11th attack on the United States. She
lays out the surroundings, atmosphere, and reactions of those around her during the attack and details her own personal motivations
for joining the military, her need to take control and help those in need heal while also trying to heal herself. Grateful,
yet haunted by her experience, she provides an intimate glimpse into her time serving as a combat physician at a trauma hospital
in Balad, Iraq during the 2007 military surge. A trained geriatrician and palliative care physician she recounts the stories
of several patients that have forever shaped her life and explores the contradictions and ethical challenges she faced while
caring for them ultimately struggling with the uncertainty of whether what she was truly doing was good for those she served
or herself. 相似文献

Policies and programs designed to challenge the effects of racial discrimination (such as affirmative action) are hotly contested. Factors which have been proposed to explain opposition to these policies include racial prejudice, group threat and self‐interest, and perceptions of intergroup justice. We report the results of two random national telephone surveys which tested a theoretically based model of the predictors of policy support in post‐apartheid South Africa. The results provided limited support for Blumer's group position model. Compensatory and preferential treatment policies had different underlying predictors: Violated entitlement featured in the models of compensatory policy attitudes, but not preferential treatment policy attitudes, where threat was the strongest predictor. In addition to threat and violated entitlement, policy attitudes among the black sample were related to ingroup identification but those of the white sample were related to prejudice. The effects of these variables were in the opposite directions for the two samples: Policy support was associated with strong ingroup identification and high levels of threat among the black sample (i.e. prospective beneficiaries of the transformation policies), but with low levels of prejudice and threat among the white sample. We conclude by considering the implications that these findings have for social change programs. Copyright © 2009 John Wiley & Sons, Ltd. 相似文献

We hypothesized and observed that the degree to which students endorsed entity theories - the view that intelligence is fixed rather than malleable - attenuated the affective benefits and exacerbated the achievement drawbacks of positive fantasies in the academic domain. Positive fantasies only predicted low anger and anxiety for schoolchildren who did not strongly endorse entity theories (Study 1), and positive fantasies only predicted poor final school grades for vocational students who did strongly endorse entity theories (Study 2). An experiment indicated that for university students with stronger entity theories, positive fantasies demanded relatively little attention (Study 3), suggesting that positive fantasies obscure the opportunity for the preemptive self-regulation which promotes successful performance. 相似文献
