从词频和新旧效应探讨再认测验中的定向遗忘

本文采用字表方式,从高低词频和新旧效应角度,探讨内隐和外显测验中定向遗忘效应的存在性及其机制问题。结果发现:(1)低频词在两种测验中都存在定向遗忘效应,而高频词仅存在于外显测验中。(2)两种测验中都存在指示记住的新旧效应,而外显测验中不存在指示忘记的新旧效应。由此推断,测验间在没有"意识和无意识"相互污染的理想情况下,只有外显测验可获得定向遗忘效应;定向遗忘的机制可能是选择性编码机制。     

Researcher and clinician: Role conflict and resolution

Group therapy investigations are often conducted by researchers rather than by experienced clinicians who also possess research expertise. Given the fact that doctorally prepared clinicians must demonstrate research competence in their education programs, it is surprising that there is not more research on group therapy. The literature indicates that research and group psychotherapy practice are considered quite separate entities. However, there is much that both processes have in common. The principal investigator's experience during a group psychotherapy research project suggested that the conflict between the roles of researcher and clinician may not be due to differences in the external processes but rather to difficulties in trying to combine them within one person. The value of the researcher-clinician is elaborated, and recommendations are offered.This paper was supported by a grant from the Group Psychotherapy Foundation.     

The Youth Public Arts Program: Interpersonal and Intrapersonal Outcomes for At-Risk Youth

This article provides the findings of a program evaluation of the Youth Public Arts Program, a long-standing community-based art program that serves at-risk youth in eastern North Carolina. The program evaluation was undertaken to examine the art skills, social and interpersonal skills, and community involvement of the participants. The study included four focus groups and telephone surveys with a total of 38 stakeholders (program participants, parents of participants, program staff, and referral sources). Results indicated that the at-risk youth had gains in both interpersonal and intrapersonal skills, including family relationships, peer relationships, community interaction, increased art skills, confidence, and self-regulation. This article adds to the very limited literature on community-based art programs for youth.     

The Relations Between Patterning,Executive Function,and Mathematics

Patterning, or the ability to understand patterns, is a skill commonly taught to young children as part of school mathematics curricula. It seems likely that some aspects of executive function, such as cognitive flexibility, inhibition, and working memory, may be expressed in the patterning abilities of children. The primary objective of the present study was to examine the relationship between patterning and executive functioning for first grade children. In addition, the relations between patterning, executive functioning, mathematics, and reading were examined. The results showed that patterning was significantly related to cognitive flexibility and working memory, but not to inhibition. Patterning, cognitive flexibility, and working memory were significantly related to mathematical skills. Only patterning and working memory were significantly related to reading. Regression analyses and structural equation modeling both showed that patterning had effects on both reading and mathematics measures, and that the effects of cognitive flexibility were entirely mediated by patterning. Working memory had independent effects on reading and mathematics, and also effects moderated by patterning. In sum, these findings suggest that cognitive flexibility and working memory are related to patterning and express their effects on reading and mathematics in whole or in part through patterning.     

Effects of verbal ability and fluid intelligence on children's emotion understanding

This study investigated the role of verbal ability and fluid intelligence on children's emotion understanding, testing the hypothesis that fluid intelligence predicts the development of emotion comprehension over and above age and verbal ability. One hundred and two children (48 girls) aged 3.6–6 years completed the Test of Emotion Comprehension (TEC) that comprised external and mental components, the Coloured Progressive Matrices and the Test for Reception of Grammar. Regression analysis showed that fluid intelligence was not equally related to the external and mental components of the TEC (Pons & Harris, 2000). Specifically, the results indicated that the external component was related to age and verbal ability only, whereas recognition of mental emotional patterns required abstract reasoning skills more than age and verbal ability. It is concluded that the development of fluid intelligence has a significant role in the development of mental component of emotion comprehension.     

Locus of Control and Anti‐Immigrant Sentiment in Canada,the United States,and the United Kingdom

Using data collected in Canada, the United States, and the United Kingdom, this article examines the determinants of attitudes toward immigrants. In particular, we draw on the literature in social psychology to explore the role of locus of control in promoting more ethnocentric and restrictive attitudes towards immigration. We conceptualize control at three levels: (1) perceptions of individual locus of control (i.e., feeling that one can control one's own circumstances), (2) perceptions of societal control (i.e., feeling that one's country has control over immigration), and (3) perceptions of an outgroup's locus of control (i.e., feeling that an outgroup's social circumstances are attributable to dispositional rather than external factors). Results show that all three measures of control are important predictors of negative attitudes toward immigrants: Those who feel in control (personally or as a society) are less hostile towards immigrants, while those who attribute negative outcomes to immigrants' predispositions are also more hostile. Results also suggest that measures of control are related to, but distinct from, both partisanship and racial prejudice.     

Why and for whom does the pressure to help hurt others? Affective and cognitive mechanisms linking helping pressure to workplace deviance

Scholars are paying increasing attention to the “dark side” of citizenship behavior. One aspect of this dark side that has received relatively scant attention is “helping pressure”—an employee's perception that s/he is being encouraged to, or otherwise feels that s/he should, enact helping behavior at work. Drawing from theory associated with work stress, we examine affective and cognitive mechanisms that potentially explain why helping pressure, counterintuitively, may lead employees to engage in deviant behavior instead. Beyond examining these possible mechanisms, we also answer calls to identify a potential buffer to these effects. Drawing from self-determination theory, we examine how an employee's intrinsic motivation for citizenship may lessen the deleterious consequences of helping pressure at work. In two studies (a within-individual experience-sampling study and a two-wave between-individual study), we find consistent evidence that helping pressure has a positive indirect relationship with deviant behavior through increased negative affect. Further, we find evidence that intrinsic motivation for citizenship weakens the positive relationship of helping pressure with negative affect, buffering the indirect effect on subsequent deviant behavior. Theoretical and practical implications of these findings for the study of helping pressure at work are discussed.

Self‐Stigma,Mental Health Literacy,and Health Outcomes in Integrated Care

The authors describe research on the self‐stigma of mental illness and help seeking, mental health literacy, and health outcomes in an integrated care medical center. Results revealed that self‐stigma of mental illness and self‐stigma of seeking help had an inverse relationship with mental health literacy. No statistically significant relationships were found between health outcomes, either type of self‐stigma, and mental health literacy. The authors discuss these and other findings and offer research and counseling implications.     

Persistence and relapse of reinforced behavioral variability

The present study examined persistence and relapse of reinforced behavioral variability in pigeons. Pigeons emitted four‐response sequences across two keys. Sequences produced food according to a lag schedule, in which a response sequence was followed by food if it differed from a certain number of previous sequences. In Experiment 1, food was delivered for sequences that satisfied a lag schedule in both components of a multiple schedule. When reinforcement was removed for one component (i.e., extinction), levels of behavioral variability decreased for only that component. In Experiment 2, food was delivered for sequences satisfying a lag schedule in one component of a multiple schedule. In the other component, food was delivered at the same rate, but without the lag variability requirement (i.e., yoked). Following extinction, levels of behavioral variability returned to baseline for both components after response‐independent food delivery (i.e., reinstatement). In Experiment 3, one group of pigeons responded on a lag variability schedule, and the other group responded on a lag repetition schedule. For both groups, levels of behavioral variability increased when alternative reinforcement was suspended (i.e., resurgence). In each experiment, we observed some evidence for extinction‐induced response variability and for variability as an operant dimension of behavior.
