The way a space is learned can result in a mental mapthat is either temporally or spatially organized (Curiel & Radvansky, 1998). The present study examined the availability of spatial information under maplearning conditions where either temporal or spatial organization has been previously observed. The finding was that people were fairly accurate in tasks that explicitly required the use of spatial information. However, there was a particular advantage for having a spatially organized mental mapin a direction judgment task, especially for short distances where fine-grained knowledge was required. In contrast, there was no clear advantage for either group in a distance estimation task. These data are interpreted in the context of Huttenlocher’s category adjustment model.  相似文献

Two studies of Puerto Rican youths' development on the U.S. mainland examined the consequences of perceived racial/ethnic discrimination on mental health. In Study I, children were found to have a low likelihood of perceiving discrimination, whereas in Study 2, nearly half of the adolescent sample reported perceiving racial/ethnic discrimination. Although both groups scored high on multiple indicators of mental health, perceiving discrimination and worrying about discrimination were negatively associated with some dimensions of self-esteem and positively associated with depression and stress. Adolescents were aware of negative stereotypes about Puerto Ricans, and nearly half of them related discriminatory instances. Results suggest that both perceiving discrimination and anxiety regarding discrimination can serve as risk factors for the mental health of this population.  相似文献

Central galanin administration blocks consolidation of spatial learning   总被引:1,自引:0,他引:1  
Galanin is a neuropeptide that inhibits the evoked release of several neurotransmitters, inhibits the activation of intracellular second messengers, and produces deficits in a variety of rodent learning and memory tasks. To evaluate the actions of galanin on encoding, consolidation, and storage/retrieval, galanin was acutely administered to Sprague-Dawley rats at time points before and after training trials in the Morris water maze. Intraventricular administration of galanin up to 3h after subjects had completed daily training trials in the Morris water task impaired performance on the probe trial, indicating that galanin-blocked consolidation. Pretreatment with an adenylate cyclase activator, forskolin, prevented the deficits in distal cue learning produced by galanin. Di-deoxyforskolin, an inactive analog of forskolin, had no effect. These results provide the first evidence that galanin interferes with long-term memory consolidation processes. A potential mechanism by which galanin produces this impairment may involve the inhibition of adenylate cyclase activity, leading to inhibition of downstream molecular events that are necessary for consolidation of long-term memory.  相似文献

This study was designed to examine the role of both sexual orientation and gender-related personality traits in disordered eating attitudes and behavior, including body dissatisfaction. Self-report measures assessing negative and positive gender traits,body dissatisfaction, drive for thinness, dietary restraint, and bulimic symptoms were administered to 266 participants (64 lesbians, 73 heterosexual women, 69 gay men, and 60 heterosexual men; 85% Anglo-Australian Caucasians, 15% Caucasians from Non-English-speaking backgrounds). Consistent with previous research, gay men scored significantly higher than heterosexual men on body dissatisfaction and dietary restraint, whereas lesbians scored significantly lower in comparison to the heterosexual women on body dissatisfaction, drive for thinness, dietary restraint, and bulimia. For men, the additional amount of variance accounted by the gender traits was significantly higher than that accounted for by sexual orientation. For the women, the gender traits also accounted for an additional significant amount of variance; however, overall the amount of variance accounted for by sexual orientation was greater. However, for both men and women, irrespective of their sexual orientation, it was higher scores on negative femininity that predicted higher levels of disordered eating. These results are consistent with previous studies that have found support for the femininity hypothesis in disordered eating.  相似文献

This study evaluates the psychosocial correlates of anger-related traits. Participants include New York City traffic enforcement agents (TEAs), who issue summonses for vehicular and parking violations and are frequently confronted by angry motorists. This sample of TEAs is 53% African American and 57% female. Participants completed surveys at 2 points, 4 months apart, which measured attitudinal, affective, and expressive components of hostility and anger, as well as dimensions of workplace psychosocial response. Results indicate that trait anger-in was positively associated with frequency of conflict, anger intensity, and burnout in cross-sectional analyses; and positively associated with frequency of conflict in prospective analyses. Trait anger was positively associated with an increase in burnout over a 4-month period. These findings provide support for the transactional model of hostility and health and have implications for worksite interventions promoting cardiovascular health.  相似文献

The relationships between susceptibility to leading questions and several individual differences variables—namely number and mass conservation; self-rated social desirability; and teacher-rated assertive social skills, shyness-anxiousness, and acting out—were examined for 36 first graders. As predicted, children whose conservation skills were more advanced were least susceptible to leading questions. However, there was no reliable direct association with any of the four personality variables assessed. Results were interpreted as evidence that the ability to simultaneously consider multiple dimensions may be one general cognitive factor underlying developmental and individual differences in susceptibility to leading questions.  相似文献

Discussion     
While in no way denying the interest of the study of “Theories of Mind”, the discussion tends to show that, in the tasks described in the papers, the development of abilities to process perceptual and verbal information is sufficient in itself to fully account for changes in observed responses. Whether the issue is false beliefs or the distinction between appearance and reality, children's behavior is highly dependent on their working memory span, their operational efficiency (action coordination) and their current state of knowledge. “Theories of Mind” emerge as indices of cognitive development. Their adaptive value is more problematical.  相似文献

Some influences of accent structure on melody recognition   总被引:1,自引:0,他引:1  
Two experiments were carried out to investigate the roles of joint accent structure and familiarity in delayed recognition of relatively long tonal melodies. Melodic themes of target melodies were defined by correlating contour-related pitch accents with temporal accents (accent coupling) during an initial familiarization phase. Later, subjects gave recognition responses to key-transposed versions of the target melodies as well as to decoys with same and different contour accent patterns. In Experiment 1, all to-be-recognized melodies occurred both in an original rhythm, which preserved accent coupling, and in a new rhythm, which did not. Listeners were best at distinguishing targets from different decoys, especially in the original rhythm. In Experiment 2, the familiarity of target tunes and the rhythmic similarity in recognition were varied. Similar rhythms preserved accent coupling, whereas dissimilar rhythms did not. Listeners were most adept in distinguishing familiar targets from different decoys (Experiment 2A), particularly when they appeared in novel but similar rhythms. However, in similar rhythm conditions, listeners also frequently mistook same decoys for targets. With less familiar targets (Experiment 2B), these effects were attenuated, and performance showed general effects of pitch contour.  相似文献

This study examined cultural pluralism along the lines of hierarchy among eight large public accounting firms. Although no significant cultural differences among the different functional units (auditing, tax, and management consulting) of the firms were found, culture was found to be related to hierarchical level. Specifically, top level managers (partners) perceived the culture of their organization as significantly more innovative and supportive than did individuals at lower hierarchical levels (managers/supervisors and senior/ staff accountants). Creativity was not affected by culture.  相似文献

Community engagement (CE) at Rhodes University (RU) and community psychology draw on similar principles: using an asset-based community development approach; recognising and drawing on the skills, capabilities, and knowledge of all parties, which they contribute to a partnership. Working from a strategic model of engagement, mutuality is foreground in all CE activities, where both student volunteers and community partners jointly benefit from the engagement. This paper examines CE at RU and how CE principles are translated into practise, using Siyakhana@Makana (S@M) as a case study. In S@M, a 19-week-long volunteer programme, community partners and student volunteers are jointly involved in planning, executing, and evaluating CE activities together. This paper illustrates how being involved in such CE activities has enabled community partners to mobilise for effective change in their communities. Community partners reflect on how they have been empowered to taken on leadership roles, addressing local challenges in collaborative ways, while drawing on the skills and knowledge that they have gained through their engagements in S@M. This resonates with the social action model of community psychology, a participatory approach that seeks to mobilise people to bring about change in the contexts in which they live.  相似文献
