In this study, we examined the relationship between needs for achievement (n Ach) and power (n Pwr) and the importance of six dimensions of life success among a sample of 454 managerial women and men in southeastern Florida. Results showed that n Ach was significantly correlated with all four work-related success dimensions: status/wealth, personal fulfillment, and professional fulfillment (positively), and with security (negatively). N Ach was not correlated with either of the two nonwork-related success dimensions of family relationship and social contribution. N Pwr was significantly correlated with all the same work-related success dimensions except professional fulfillment; it was also correlated significantly with the non work-related dimension of social contribution but not with family relationships.  相似文献

This study investigated the risk propensity and self-actualization of public librarians with regard to censorship behavior. A sample of 169 librarians from the province of Ontario responded to a 124-item mail questionnaire that incorporated a number of previously validated instruments, including the Adorno F Scale (Adorno, Frenkel-Brunswick, Levinson, & Sanford, 1950), the Short Index of Self-Actualization (Jones & Crandall, 1986), and the Choice Dilemmas Questionnaire (Kogan & Wallach, 1964). Analyses indicated that the librarians were generally liberal in attitude but conservative in behavior with respect to censorship and book selection. Moreover, they appear to have been averse to taking risks and not selfactualized. These results are discussed in terms of cognitive dissonance theory and risk propensity theory.  相似文献

Homophily, a term used to describe the tendency to associate with similar others, serves as a basis for attraction among children. The converse may also be true. Dissimilarity appears to contribute to dislike. In one of the only published studies to examine homophily and its converse, D. W. Nangle, C. A. Erdley, and J. A. Gold (1996) found that children were liked by peers who were similar to them in social status and behavioral style and disliked by peers who were dissimilar to them in social status and behavioral style. Examining gender influences, we were only able to partially replicate their findings in the present study. That is, evidence of homophily was found only for girls. In contrast, dissimilarity contributed to dislike for both genders, but was especially evident for boys. With respect to age, prosocial behavior appeared to have a more positive valence among younger girls. whereas aggressive behavior appeared to have a more negative valence among older boys. Attempts to reconcile these findings with those of the Nangle et al. (1996) investigation and the implications for understanding peer processes, gender influences, and behavior problems are discussed.  相似文献

To investigate attentional impairment in schizophrenia, the authors examined the performance of 22 patients with schizophrenia and 16 healthy control subjects in 4 visual search tasks that varied in perceptual requirements and in the need for precise attentional control. The rate of search was slowed in the patients in all tasks. However, the degree of slowing was largest in tasks requiring precise attentional control and smallest in tasks that were perceptually difficult but required less attentional control. This pattern of results indicates that the primary impairment of attention in schizophrenia lies in the control of attention and not in the selection processes that operate once attention has been directed to an object.  相似文献

Sibling collusion is a process by which siblings form coalitions that promote deviance and undermine parenting. Collusive sibling processes were identified and measured using macro ratings of videotaped family interactions. Hypotheses were tested on a multiethnic sample of urban youth, with a target child identified as either high risk (n = 26) or normative (n = 26), and their families. Siblings in families with a high-risk target child showed reliably higher rates of collusion than those in families with a normative target child. Sibling collusion also accounted for variance in problem behavior after controlling for involvement with deviant peers. Findings suggest that deviant conduct forms a common ground among siblings, potentially amplifying risk of mutuality in problem behavior during early adolescence. These data also indicate that attention to sibling relationship processes is relevant to family interventions designed to mitigate the development of behavior problems.  相似文献

The September 11, 2001, attack on New York City was the largest human-made disaster in United States history. In the first few days after the attack, it became clear that the scope of the attacks (including loss of life, property damage, and financial strain) was unprecedented and that the attacks could result in substantial psychological sequelae in the city population. Researchers at the Center for Urban Epidemiologic Studies at the New York Academy of Medicine designed and implemented an assessment of the mental health of New Yorkers 5-8 weeks after the attacks. To implement this research in the immediate postdisaster period, researchers at the center had to develop, in a compressed time interval, new academic collaborations, links with potential funders, and unique safeguards for study respondents who may have been suffering from acute psychological distress. Results of the assessment contributed to a New York state mental health needs assessment that secured Federal Emergency Management Agency funding for mental health programs in New York City. This experience suggests that mechanisms should be in place for rapid implementation of mental health assessments after disasters.  相似文献

Suppressing a thought often results in postsuppressional rebound, that is, a subsequent increase in the incidence of the suppressed thought. The present study was dcsigned to distinguish between two explanations of rebound: Wegner's 1994 ironic monitoring theory and Liberman and Forster's 2000 motivational account. Participants (99 Deakin University students) first suppressed, then expressed, thoughts of a white bear. In some conditions, a delay--presented as occurring either intentionally or unintentionally--between suppression and expression was introduced. In other conditions, participants concurrently completed a memory task and were encouraged to antribute the difficulty of suppression either to this task or to the requirement of suppression. An intentional delay, but not an unintentional delay, reduced rebound, while attributing difficulty to the suppression requirement was associated with greater rebound than was attributing it to the memory task. The results are interpreted as supporting Liberman and Forster's motivational account of rebound.  相似文献

The present experiment tested male Sprague-Dawley rats for spontaneous alternation performance in a food-rewarded Y-shaped maze. Microdialysis samples, later assessed for acetylcholine concentration, were collected from the hippocampus and striatum of each rat prior to and during testing; testing sessions lasted 20 min. Early in testing, rats alternated at a rate of 72%. Alternation scores increased throughout the 20-min testing session and reached 93% during the last 5 min. The behavioral findings suggest that, during testing, rats changed the basis for their performance from a spatial working memory strategy to a persistent turning strategy. ACh release in both hippocampus and striatum increased at the onset of testing. Increases in ACh release in the striatum began at 18% above baseline during the first 5 min of testing and steadily increased reaching 58% above baseline during the final 5 min. The progressive rise of striatum ACh release during testing occurred at about the time rats adopted a persistent turning strategy. In contrast, ACh release in the hippocampus increased by 50% with the onset of testing and remained at this level until declining slightly during the last 5 min of testing. The relative changes in ACh release in the striatum and hippocampus resulted in a close negative relationship between the ratio of ACh release in the hippocampus/striatum and alternation scores.  相似文献

This study reports evidence that patients with schizophrenia demonstrate a slowing of working memory (WM) consolidation, which is the process of transforming transient perceptual representations into durable WM representations. Sixteen schizophrenia patients and 16 healthy control participants performed a task measuring the visual WM consolidation rate in a change-detection paradigm. A target display containing 3 colored squares was followed by a variable delay of 17-483 ms, a pattern mask, and then a test stimulus. This pattern mask does not interfere with perception but disrupts WM consolidation. Control participants reached no-mask performance by 250 ms, indicating completed WM consolidation, whereas patients failed to reach no-mask performance by 483 ms. Slowed consolidation may play an important and largely unrecognized role in schizophrenia.  相似文献
