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

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

Traditional visual search experiments, where the researcher pre-selects video-based scenes for the participant to respond to, shows that elite players make more efficient decisions than non-elites, but disagree on how they temporally regulate their gaze. Using the vision-in-action [J.N. Vickers, J. Exp. Psychol.: Human Percept. Perform. 22 (1996) 342] approach, we tested whether the significant gaze that differentiates elite and non-elite athletes occurred either: early in the task and was of more rapid duration [A.M. Williams et al., Res. Quart. Exer. Sport 65 (1994) 127; A.M. Williams and K. Davids, Res. Quart. Exer. Sport 69 (1998) 111], or late in the task and was of longer duration [W. Helsen, J.M. Pauwels, A cognitive approach to visual search in sport, in: D. Brogan, K. Carr (Eds.), Visual Search, vol. II, Taylor and Francis, London, 1992], or whether a more complex gaze control strategy was used that consisted of both early and rapid fixations followed by a late fixation of long duration prior to the final execution. We tested this using a live defensive zone task in ice hockey. Results indicated that athletes temporally regulated their gaze using two different gaze control strategies. First, fixation/tracking (F/T) gaze early in the trial were significantly shorter than the final F/T and confirmed that the elite group fixated the tactical locations more rapidly than the non-elite on successful plays. And secondly, the final F/T prior to critical movement initiation (i.e. F/T-1) was significantly longer for both groups, averaging 30% of the final part of the phase and occurred as the athletes isolated a single object or location to end the play. The results imply that expertise in defensive tactics is defined by a cascade of F/T, which began with the athletes fixating or tracking specific locations for short durations at the beginning of the play, and concluded with a final gaze of long duration to a relatively stable target at the end. The results are discussed within the context of gaze research in open and closed skills, as well as theoretical models of long-term memory and decision making in sport.  相似文献

The federal regulations of human research were written to permit the use of discretion so that research can fit the circumstances under which it is conducted. For example, the researcher and institutional review board (IRB) could waive or alter some informed consent elements if they deem this the morally and scientifically best way to conduct the research. To do so, however, researchers and IRBs would first have to use mature moral and scientific judgment. They might also have to rely on empirical research to discover the most effective way to act on their moral sense (e.g., to discover how best to approach potential research participants and explain the nature and purpose of the research participation for which they are being recruited, to ensure comprehension and competent decision making). On discovering the most ethical way to proceed, they would then need to look to the federal regulations of human research to discover how to document their decision and justify it within that somewhat flexible regulatory structure. Unfortunately, many IRBs and researchers fail to take these sensible steps to solve ethical problems and proceed immediately to a default requirement of the regulations that places science at odds with the regulations and, ostensibly, with ethics. The following articles in this special issue are about the process of learning to engage in ethical problem solving and using the flexibility permitted by the federal regulations. These articles extricate researchers from the mindset that has gotten them into trouble, and, ideally, provoke them to use mature common sense and moral judgment.  相似文献
