If people work on a hard task before proceeding to one of intermediate difficulty, success will be relevant (predictive of future success) while failure will be irrelevant (not predictive of future failure). However, if they work first on an easy task, success will be irrelevant (not predictive of future success) while failure will be relevant (predictive of future failure). Previous research thus suggests that experience with hard tasks should always lead to more favorable evaluations of one's performance and better future performance than experience with easy tasks. The present study tested these predictions by manipulating initial expectancy (high or low), perceived difficulty of a set of practice problems (practice problems easier, harder, or equal in difficulty to those on a subsequent test), and practice problem feedback (success or failure). As predicted, experience with hard practice problems was most beneficial, regardless of the level of the feedback which students received. This was more true for males than females and for students with high ability than students with low ability. 相似文献

Two studies are reported on multiple forced recall following a single visual presentation of a sequence of pictures or words. In both experiments, a hypermnesic memory function (in which performance improved with repeated recall) was obtained for pictures, while a flat, nonincremental function was obtained for words. Interpolation of intervals of thinking between recall trials further enhanced hypermnesia for pictorial items. Retrieval, whether overt (recall trials) or covert (thinking), apparently produces increased net recovery of pictures but not words. 相似文献

Antecedents Of Trust: Establishing A Boundary Condition For The Relation Between Propensity To Trust And Intention To Trust 总被引:1,自引:0,他引:1

Two studies were conducted to examine the antecedents of intention to trust proposed by Mayer, Davis, and Schoorman [1995, Academy of Management Review, 20(3), 709–734]. In their model, intention to trust is influenced by the perceived characteristics of the trustee and the predisposition of the trustor. We found that perceived ability, benevolence, and integrity of the trustee predicted an individuals intention to trust. Propensity to trust, that is, an individuals disposition to trust, correlated with intention to trust when information about trustworthiness was ambiguous, but did not correlate with intention to trust when information about trustworthiness was clear. The notion of strong and weak situations is used to argue that situational strength is a boundary condition of the relation between propensity to trust and intention to trust. 相似文献

The present study examined the process of shared leadership in 45 ad hoc decision-making teams. Each team member's leadership behavior (n = 180) was assessed by behaviorally coding videotapes of the teams' discussions. The within-team patterns of leadership behavior were examined using cluster analysis. Results indicated that the likelihood of a team experiencing a full range of leadership behavior increased to the extent that multiple team members shared leadership, and that teams with shared leadership experienced less conflict, greater consensus, and higher intragroup trust and cohesion than teams without shared leadership. This study supports previous findings that shared leadership contributes to overall team functioning, and begins to delineate the extent to which team members may naturally share leadership. 相似文献

Emergency Department Youth Patients With Suicidal Ideation or Attempts: Predicting Suicide Attempts Through 18 Months of Follow‐Up 下载免费PDF全文
Joan Rosenbaum Asarnow PhD Michele Berk PhD Lily Zhang MS Peter Wang BA Lingqi Tang PhD 《Suicide & life-threatening behavior》2017,47(5):551-566
This prospective study of suicidal emergency department (ED) patients (ages 10–18) examined the timing, cumulative probability, and predictors of suicide attempts through 18 months of follow‐up. The cumulative probability of attempts was as follows: .15 at 6 months, .22 at 1 year, and .24 by 18 months. One attempt was fatal, yielding a death rate of .006. Significant predictors of suicide attempt risk included a suicide attempt at ED presentation (vs. suicidal ideation only), nonsuicidal self‐injurious behavior, and low levels of delinquent symptoms. Results underscore the importance of both prior suicide attempts and nonsuicidal self‐harm as risk indicators for future and potentially lethal suicide attempts. 相似文献

Over the past several decades, significant advances have been made in our understanding of the basic stages and mechanisms
of mammalian brain development. Studies elucidating the neurobiology of brain development span the levels of neural organization
from the macroanatomic, to the cellular, to the molecular. Together this large body of work provides a picture of brain development
as the product of a complex series of dynamic and adaptive processes operating within a highly constrained, genetically organized
but constantly changing context. The view of brain development that has emerged from the developmental neurobiology literature
presents both challenges and opportunities to psychologists seeking to understand the fundamental processes that underlie
social and cognitive development, and the neural systems that mediate them. This chapter is intended to provide an overview
of some very basic principles of brain development, drawn from contemporary developmental neurobiology, that may be of use
to investigators from a wide range of disciplines. 相似文献

The authors address questions about the rate that depressive symptoms emerge, developmental and gender differences in this rate, and differences between parent and child estimates of this rate. In a 12-wave, cohort-sequential, longitudinal design, 1,570 children (Grades 4-11) and parents completed reports about children's depression. Cross-domain latent growth curve analysis revealed that (a) the rate of symptom growth varied with developmental level. (b) gender differences symptom growth preceded emergence of mean level gender differences, (c) the rate of symptom development varied with age, and (d) parent-child agreement about rate of symptom change was stronger than agreement about time-specific symptoms. The authors suggest that predictability of depressive symptoms varies with age and the dimension under investigation. 相似文献

The association between childhood exposure to domestic violence and later intimate partner violence (IPV) perpetration in adulthood has been well established in the literature. However, the literature examining the factors of exposure that contribute to perpetration in adulthood is fraught with mixed findings, with some studies finding a direct link between childhood domestic violence exposure and later IPV perpetration and others ruling out a link after controlling for other contextual barriers such as community violence and socioeconomic status. This study examined 124 non-treatment-seeking and unadjudicated adult male IPV perpetrators and found exposure to domestic violence in childhood contributes to the normalization of violence, which could predict future adult IPV perpetration. Practice implications are discussed, namely primary and secondary prevention of intimate partner violence. 相似文献

We investigated the order of acquisition of concepts and cognitive processes in children with emotional and behavioral difficulties and the extent to which these children show similarity to ordinary children in sequence and structure of development. Similarity in developmental sequence was strongly supported by scalogram analyses and has clear implications for organizing teaching, but similarity in structure was less clear. Cognitive processes, however, and the nature of the children's reasoning were clarified by the method of exploration used. This was particularly fruitful for providing insight into the difficulties children may have. The findings thus contribute to understanding with a view toward furthering concept development in children with emotional and behavioral difficulties. 相似文献
