Five experiments are reported in which subjects were asked to remember short, visually presented sequences of whole body movement patterns, words, and spatial positions. The items were recalled in order in a memory span paradigm. During presentation of the items to be remembered subjects simply watched, or they carried out a concurrent activity involving articulatory suppression, movement to external spatial targets, or body-related movement. When the movement patterns to be remembered were familiar to subjects, movement span was not disrupted by articulatory suppression or movement to spatial targets but was disrupted by body-related movement. This movement suppression task, however, did not interfere with performance on a spatial span task or on verbal span. It is concluded that the memory for patterns of limb movement differs from memory for movement to spatial targets and that accounts of visuo-spatial processes in working memory involve the latter type of movement.  相似文献

Adolescence is a unique developmental period when the salience of social and emotional information becomes particularly pronounced. Although this increased sensitivity to social and emotional information has frequently been considered with respect to risk behaviors and psychopathology, evidence suggests that increased adolescent sensitivity to social and emotional cues may confer advantages. For example, greater sensitivity to shifts in the emotions of others is likely to promote flexible and adaptive social behavior. In this study, a sample of 54 children and adolescents (age 8–19 years) performed a delayed match‐to‐sample task for emotional faces while undergoing fMRI scanning. Recruitment of the anterior cingulate and anterior insula when the emotion of the probe face did not match the emotion held in memory followed a quadratic developmental pattern that peaked during early adolescence. These findings indicate meaningful developmental variation in the neural mechanisms underlying sensitivity to changes in the emotional expressions. Across all participants, greater activation of this network for changes in emotional expression was associated with less social anxiety and fewer social problems. These results suggest that the heightened salience of social and emotional information during adolescence may confer important advantages for social behavior, providing sensitivity to others’ emotions that facilitates flexible social responding.  相似文献

Research on dynamic stereotypes of women has shown that women perceive large differences between contemporary women and women who lived in the past in terms of agentic (or masculine) traits. This temporal discrepancy in agentic attributes of women may suggest that agency is not a stable trait of women and may result in impaired performance in domains associated with agency, such as quantitative reasoning. We propose that women who think that agency has always characterized their gender group would perform better in quantitative tasks. Indeed, we found that as the difference between agency attributed to present and past women decreased, U.S. college women’s (n?=?80) accuracy in a quantitative test increased (Study 1). Further, reading a text about women’s achievements in the history of science reduced the discrepancy between agency attributed to past and present women and had an indirect positive effect on quantitative performance by 150 U.S. college women (Study 2). Findings suggest that women’s participation and performance in science could be improved by raising awareness of women’s historical achievements in male-dominated areas.  相似文献

The commitment of transplant physicians to protect the physical and psychological health of potential donors is fundamental to the process of living donor organ transplantation. It is appropriate that strict regulations to govern an individual's decision to donate have been developed. Some may argue that adherence to such regulations creates a doctor-patient relationship that is rooted in paternalism, which is in drastic contrast with a doctor-patient relationship that is rooted in patients' autonomy, characteristic of most other operative interventions. In this article we analyze the similarities between cosmetic plastic surgery and living donor surgery as examples of surgeries governed by different ethical principles. It is interesting that, while the prevailing ethical approach in living donor surgery is based on paternalism, the ethical principle guiding cosmetic surgery is respect for patients' autonomy. The purpose of this article is not to criticize either practice, but to suggest that, given the similarities between the two procedures, both operative interventions should be guided by the same ethical principle: a respect for patients' autonomy. We further suggest that if living organ donation valued donors' autonomy as much as cosmetic plastic surgery does, we might witness a wider acceptance of and increase in living organ donation.  相似文献

This brief report describes results from an evaluation of NAMI Basics, a peer-delivered family education program for family caregivers of children and adolescents with mental illness. Over six classes, family members are given information (e.g. education about mental illness and treatments), skills training (e.g. family communication skills) and advocacy support. We report data from 36 caregivers who completed pre and posttest instruments measuring self-care, empowerment, and family problem-solving and communication skills. Results showed significant improvements in self-care, empowerment, and “incendiary” family communication after participation in the program. Results suggest that NAMI Basics may improve both parental functioning and familial processes. Implications and future directions are discussed.  相似文献

Parkinson's disease (PD) is a progressive neurodegenerative disease primarily characterised by motor symptoms. However, another feature of PD which is receiving increasing attention is the phenomenon of impulse control disorders (ICDs), such as pathological gambling. To date, research into ICDs in PD has centred on a biomedical model of cause, related to the effects of dopamine replacement therapy. However, there are several areas of discrepancy in the current biomedical account of ICDs in PD. In addition, we argue that social and psychological factors also need to be considered to achieve a more complete understanding of the phenomenon. We present a novel conceptual model which combines biomedical and psychosocial factors in the genesis of ICDs in PD and use the model to identify a number of potential treatment intervention points and to highlight important outstanding questions concerning the inter-relationship between psychosocial and biomedical factors in the genesis of ICDs in PD.  相似文献

Little is known about positive development across the transition from adolescence to young adulthood. The purpose of this paper was to use longitudinal data from a large community sample, the Australian Temperament Project, to investigate prospective associations between positive development at age 19?C20?years and changes in social, health, and behavioral outcomes at 23?C24?years. Data from 890 young adults (61.7% women) were analyzed using path analysis. Emotional health, physical well-being, friendship quality, reduced antisocial behavior, and positive development in young adulthood were predicted by higher levels of positive development in late adolescence, after controlling for baseline levels of respective outcomes, gender, and family socioeconomic status. Parent relationship quality and alcohol use were not significantly predicted. Based on these findings, interventions promoting positive development during adolescence should be investigated as a potential means of yielding positive social, health, and behavioral consequences well into young adulthood.  相似文献

Autobiographical memory research documents increased access in the number of memories recalled by emerging adults (ages 18–25) with stable, clearly defined self-concepts. Very little research has examined the relationship between self-concept clarity and the episodic and semantic components of emerging adults’ autobiographical recollections. This study examined the relationship between episodic and semantic autobiographical memory and self-concept clarity in 100 undergraduate students. Contrary to previous findings, which indicated that stable self-beliefs may be used to facilitate access to episodic memories, the results suggested that self-concept clarity may not be associated with memory specificity. Instead, self-concept clarity was associated with recall of events involving cooperative social interactions. Results further showed that older age was associated with higher SCC. The implications of these results are discussed within the context of the theoretical literature concerning the relation between autobiographical memory and the development of the self-concept during emerging adulthood.  相似文献

Interactive display systems give users flexibility to tailor their visual displays to different tasks and situations. However, in order for such flexibility to be beneficial, users need to understand how to tailor displays to different tasks (to possess "metarepresentational competence"). Recent research suggests that people may desire more complex and realistic displays than are most effective (Smallman & St. John, 2005). In Experiment 1, undergraduate students were tested on a comprehension task with geospatial displays (weather maps) that varied in the number of extraneous variables displayed. Their metacognitive judgments about the relative effectiveness of the displays were also solicited. Extraneous variables slowed response time and increased errors, but participants favored complex maps that looked more realistic about one third of the time. In Experiment 2, the eye fixations of undergraduate students were monitored as they performed the comprehension task. Complex maps that looked more realistic led to more eye fixations on both task-relevant and task-irrelevant regions of the displays. Experiment 3 compared performance of experienced meteorologists and undergraduate students on the comprehension and metacognitive tasks. Meteorologists were as likely as undergraduate students to prefer geographically complex (realistic) displays and more likely than undergraduates to opt for displays that added extraneous weather variables. However, meteorologists were also slower and less accurate with complex than with simple displays. This work highlights the importance of empirically testing principles of visual display design and suggests some limits to metarepresentational competence.  相似文献
