Team tenure and team performance: A meta-analysis and process model

Team tenure is a key component of models of team effectiveness. However, the nature of the relationship between team tenure and team performance is unclear due to underdeveloped theory on the nature of team tenure, various unintegrated theoretical conceptualizations of team tenure, and mixed empirical findings. Further, there is a lack of theory as to the intervening team processes and emergent states that account for the “black box” of the team tenure–team performance relationship. Accordingly, we conducted meta-analyses of the relationships of team tenure with team processes and performance. Our results, based on 622 effect sizes reported in 169 studies, show that team tenure, conceptualized as additive team tenure, collective team tenure, and team tenure dispersion, is positively related to team performance. Relative weights analysis found additive team tenure to be a relatively more important predictor of team performance than collective team tenure or team tenure dispersion. We found that team cognition, motivational-affective states, and behavioral processes mediate the relationships of additive team tenure, collective team tenure, and team tenure dispersion with team performance, respectively. We discuss the implications of these findings for research and practice.     

Territorial sense of community,ethnic prejudice and political orientation

This research focused on territorial sense of community and ethnic prejudice. In particular, we related these two constructs and investigated their relationship to individual characteristics (personal political orientation, contact with immigrants, etc.) and community‐level ones (such as ethnic composition and the political orientation of the local government). Two studies were conducted in four small towns in central and southern Italy. For each study, 160 people were contacted. The instruments used were a questionnaire, the Italian Sense of Community Scale and the Blatant Prejudice Scale. The results showed that territorial sense of community is not related to ethnic prejudice or to the ethnic heterogeneity of the territory. It was also found that people with right‐wing political sympathies revealed higher levels of prejudice than people with left‐wing sympathies. Finally, in a town with a stable and consolidated left‐wing orientation of the local government we found, when the influence of personal political orientation was controlled for, lower levels of prejudice than in a town with a right‐wing orientation.

Parent Involvement in School Conceptualizing Multiple Dimensions and Their Relations with Family and Demographic Risk Factors

Parent involvement (PI) in school is associated with more positive academic performance and social competence in children. However, there are inadequacies in current measures of PI and a need for a better understanding of predictors of PI. In this study, measures were obtained from a normative sample of 387 children in kindergarten and first grade from high-risk neighborhoods in 4 different sites. First, a confirmatory factor analysis of a theoretical factor model of PI identified 6 reliable multiple-reporter PI factors: Parent–Teacher Contact, Parent Involvement at School, Quality of Parent–Teacher Relationship, Teacher's Perception of the Parent, Parent Involvement at Home, and Parent Endorsement of School. Next, the relations among 3 specific family and demographic risk factors—parental education level, maternal depression, and single-parent status—and these 6 PI factors were examined using path analyses in structural equation modeling. Results indicated that the 3 risk factors were differentially associated with the 6 PI factors: Parental education was significantly associated with 4 PI outcomes, maternal depression was significantly associated with 5 PI outcomes, and single-parent status was significantly associated with 3 PI outcomes. No significant ethnic group differences between African American and Caucasian families were found in these relations.     

作文前计划的时间因素对前计划效应的影响

采用自然实验与实验室实验相结合的方法,通过两个实验探讨作文前计划的时间因素对前计划效应的影响。结果发现,作文方式决定前计划用时,前计划用时影响前计划效应,前计划效应决定前计划形式的作用。这一结果表明,在既有前计划又有外部视觉表征的情况下,前计划本身在前计划时限与前计划形式的关系中起着决定性的作用。因为前计划的存在,使外部视觉表征的作用呈现出更为复杂的情况,从而表现为长时限前计划即充分前计划条件下,外部视觉表征具有重要意义,短时限前计划即不充分前计划条件下,计划比外部视觉表征更具价值。     

“All I remember is the black eye”: A distinctive facial feature harms eyewitness identification

Many crimes occur in which a perpetrator has a distinctive facial feature, such as a tattoo or black eye, but few eyewitness identification (ID) studies have involved such a feature. We conducted an experiment to determine how eyewitness ID performance is impacted by a distinctive facial feature, and how police could deal with this issue. Participants (N = 4,218) studied a target face with or without a black eye, and later viewed a simultaneous photo lineup either containing the target or not. For those who saw a target with a black eye, this feature was either replicated among all lineup members or was removed. The black eye harmed empirical discriminability regardless of replication or removal, which did not differ. However, participants responded more conservatively when the black eye was removed, compared to replication. Lastly, immediate confidence was consistently indicative of accuracy.     

语言演变差异与族群/方言名称对族群信息加工的影响——以广东三大汉语方言为例

语言是族群的重要文化特征之一。基于广东三大方言族群均为中原移民的史实, 探讨三大汉语方言的语言演变差异与族群/方言名称对方言讲话者对中原族群信息加工的影响。以方言为客家话、粤语和潮汕话的广东大学生为被试, 实验1采用群体参照的R/K范式, 考察不同方言讲话者对中原族群信息的记忆; 实验2采用启动Stroop范式, 考察不同方言讲话者对中原族群信息的注意偏向。结果表明, 语言演变差异与族群/方言名称影响不同方言讲话者对中原族群的信息保持, 顽强地保持祖先语言的客家方言族群对中原族群的信息加工产生群体参照效应; 语言演变差异和族群/方言名称影响方言讲话者对中原族群信息的注意偏向, 客家方言族群对中原族群的信息加工产生注意偏向。整个研究表明, 语言演变差异和族群/方言名称影响对同祖语族群的信息加工, 完整地保留汉祖语特点、强化方言与汉祖语的关系, 能够增强根祖意识, 增进对同根族群的认同。研究结果对铸牢中华民族共同体意识具有重要启示。     

Are your cross‐ethnic friends ethnic and/or national group identifiers? The role of own and perceived cross‐ethnic friend's identities on outgroup attitudes and multiculturalism

We investigated how own ethnic and national identities and perceived ethnic and national identities of close cross‐ethnic friends may predict outgroup attitudes and multiculturalism among Turkish (majority status, N = 197) and Kurdish (minority status, N = 80) ethnic group members in Turkey (M_age = 21.12, SD = 2.59, 69.7% females, 30.3% males). Compared with Turkish participants, Kurdish participants were more asymmetrical in rating their cross‐ethnic friend's identities relative to their own, reporting higher ethnic identity, but lower national identity for themselves. Own ethnic identity was negatively associated with attitudes and multiculturalism, whereas own national identity was positively associated with only attitudes. Perceived cross‐ethnic friend's national identity was positively related to both outgroup attitudes and multiculturalism. Shared national identification (high levels of own and friend's national identity) led to most positive outgroup attitudes and highest support for multiculturalism. Findings were discussed in the light of social identity and common ingroup identity models.     

Ethnicity and the stigma of disabilities

Abstract

Recent studies reveal significant differences in the attitudes held by people of various ethnic groups toward people with disabilities. We surveyed university students and community members on a scale of desired social distance from people with disabilities. Study 1 revealed that Asian-American participants were more likely to stigmatize and less likely to differentiate between individuals with physical and mental illness than were their African-American, Latin-American or European-American counterparts. Study 2 compared U.S. born with Asian born Asian-Americans and found that nativity was a useful predictor of attitudes toward people with disabilities. Asian born participants were more likely to stigmatize disabilities overall (except mental illness and old age) than U.S. born participants presumably because of the level of assimilation. These cultural differences may have health care and psychosocial implications for those who are disabled and for health care providers.     

An Exploratory Study of Discrimination of Composer Style

With an alternate study-test procedure, 254 college students attempted either to free-recall or rearrange in order items of an 11-CVC serial list to a criterion of two consecutive perfect trials. Ss learned the list with or without an isolate which was placed on each of the 11 serial positions. The main findings were as follows: (a) While the reconstruction condition required fewer study trials to criterion than the free-recall condition, the isolation effect occurred equally in both conditions. (b) The isolation effect was a function of the serial position; the effect was greater at the central positions than at the peripherals in free-recall and this trend was essentially reversed in the reconstruction condition. (c) In free-recall, no reliable and systematic spreading effect was obtained for the items immediately preceding and following the isolate; however, a positive spreading effect occurred concurrently with the isolation effect in the reconstruction condition. The isolation effect has been accounted for by a selective rehearsal assumption. Implications regarding the functional cues in serial order learning and the isolation effect in serial learning are suggested.     

Scaling Satan

The influence on social behavior of beliefs in Satan and the nature of evil has received little empirical study. Elaine Pagels (1995) in her book, The Origin of Satan, argued that Christians' intolerance toward others is due to their belief in an active Satan. In this study, more than 200 college undergraduates completed the Manitoba Prejudice Scale and the Attitudes Toward Homosexuals Scale (B. Altemeyer, 1988), as well as the Belief in an Active Satan Scale, developed by the authors. The Belief in an Active Satan Scale demonstrated good internal consistency and temporal stability. Correlational analyses revealed that for the female participants, belief in an active Satan was directly related to intolerance toward lesbians and gay men and intolerance toward ethnic minorities. For the male participants, belief in an active Satan was directly related to intolerance toward lesbians and gay men but was not significantly related to intolerance toward ethnic minorities. Results of this research showed that it is possible to meaningfully measure belief in an active Satan and that such beliefs may encourage intolerance toward others.
