领导幽默风格对团队内部学习的影响

采用幽默风格量表（HSQ）、领导成员交换量表（LMX-16）和团队内部学习问卷,以325名事业单位员工为调查对象,研究了领导幽默风格和团队内部学习、领导成员交换的关系。结果发现：（1）亲和型领导幽默和自强型领导幽默正向影响团队内部学习,嘲讽型领导幽默和自贬型领导幽默负向影响团队内部学习。（2）亲和型领导幽默和嘲讽型领导幽默对团队内部学习的影响完全通过领导成员交换起作用,自强型领导幽默对团队内部学习的影响部分通过领导成员交换起作用。（3）自强型领导幽默与嘲讽型领导幽默通过领导成员交换对团队内部学习的影响都大于亲和型领导幽默;自强型领导幽默对团队内部学习的直接效应大于自贬型领导幽默。     

A Meta-Analysis of Research on Hindsight Bias

We conducted a meta-analysis of research on hindsight bias to gain an up-to-date summary of the overall strength of hindsight effects and to test hypotheses about potential moderators of hindsight distortion. A total of 95 studies (83 published and 12 unpublished) were included, and 252 independent effect sizes were coded for moderator variables in 3 broad categories involving characteristics of the study, of measurement, and of the experimental manipulation. When excluding missing effect sizes, the overall mean effect size was Md = .39 with a 95% confidence interval of .36 to .42. Five main findings emerged: (a) effect sizes calculated from objective probability estimates were larger than effect sizes calculated from subjective probability estimates; (b) effect sizes of studies that used almanac questions were larger than effect sizes of studies that used real-world events or case histories; (c) studies that included neutral outcomes resulted in larger effect sizes than studies that used positive or negative outcomes; (d) studies that included manipulations to increase hindsight bias resulted in significantly larger effect sizes than studies in which there were no manipulations to reduce or increase hindsight bias; and (e) studies that included manipulations to reduce hindsight bias did not produce lower effect sizes. These findings contribute to our understanding of hindsight bias by updating the state of knowledge, widening the range of known moderator variables, identifying factors that may activate different mediating processes, and highlighting critical gaps in the research literature.     

自闭症谱系障碍者的面孔加工特点——眼动研究的元分析

以往研究将回避眼睛作为自闭症谱系障碍的评估标准之一, 但是一些眼动研究发现：自闭症谱系障碍者也回避注视嘴部。那么回避嘴部是否同样可以作为评估标准？本研究运用元分析, 分别将面孔核心区域中眼睛和嘴部的注视时间作为结果变量, 探讨自闭症谱系障碍者面孔加工的注视特点。通过文献检索和筛查, 共有27篇眼动文献被纳入最终的元分析, 其中眼睛注视时间生成43个独立效应量(1343人), 在嘴部注视时间生成36个独立效应量(1112人)。结果发现, 自闭症谱系障碍组对眼睛的注视时间显著少于普通被试组(d = −0.75), 但是两组在嘴部注视时间上没有显著差异(d = −0.29)。调节效应检验发现：年龄(d儿童 = −0.89, d成人 = −0.04)、面孔方向(d正立 = −0.79, d倒置 = 0.31)会影响被试对眼睛的注视时间; 年龄(d儿童 = 0.40, d成人 = −0.56)、言语智商(d匹配 = 0.63, d不匹配 = −0.62)和非言语智商的匹配性(d匹配 = 0.27, d不匹配 = −0.51)、自闭症的严重程度 (d高功能 = 0.43, d中低功能 = −0.65)和任务方式(d自由浏览 = −0.48, d辨别任务 = 0.90)则会影响被试对嘴部的注视时间。元分析结果表明嘴部注视不能作为区分自闭症谱系障碍者的指标。     

Humor as a protective factor against anxiety and depression

Background/ObjectivesEven though humor its part of everyday life, only in the last 40 years has Psychology begun to discern its impact on mental health. The aim of this paper is to explore the role that humor styles may have as protectors against anxiety and depression and their relationship with optimism.MethodA sample of 804 participants (M = 39.28; SD = 14.71) was used to analyze the uses of humor, optimism and clinical symptoms of anxiety and depression. In addition, the influence of sociodemographic variables such as sex, geographic location, age and educational level on different uses of humor was studied. Through an analysis of structural equations, the variables that had a protective or facilitating role in depression and anxiety were analyzed.ResultsMen and women differ in the use of a more aggressive humor style, and the use of affiliative humor styles decreases with age. The structural equation model indicated a good fit to the proposed theoretical model.ConclusionsHumor is a tool of everyday life and it can act for or against an individual’s mental health.     

视觉单通道还是视听双通道?——通道效应的元分析

多媒体学习中的通道效应认为,学习者对"画面+声音解说"组成的视听双通道材料的识记或理解效果要好于"画面+视觉文本"组成的视觉单通道材料,而逆转通道效应则发现了与之相反的结果。针对以往研究缺陷,重新采用元分析技术,以保持测验和迁移测验作为结果变量,考察通道效应的稳定性。经文献检索、纳入与排除后,共获91篇符合元分析的文献。经数据事先合并处理后,保持测验上生成94个独立效应量(8088人),迁移测验上生成83个独立效应量(6664人)。主效应检验发现:视听双通道在保持测验(d=0.24)和迁移测验(d=0.25)上均显著高于视觉单通道;调节效应检验发现:呈现步调、画面动态性和材料时长在保持测验和迁移测验上均对通道效应起到调节作用,通道效应主要在系统步调(d_(保持)=0.43,d_(迁移)=0.44)、动态画面(d_(保持)=0.50,d_(迁移)=0.59)及短时材料(d_(保持)=0.38,d_(迁移)=0.33)条件下出现;所有结果均未发现逆转通道效应。结论认为:相比视觉单通道,当图文信息以视听双通道呈现时更有利于促进学习者对多媒体学习材料的识记和理解,支持了多媒体学习认知理论;呈现步调、画面动态性以及材料时长是通道效应的重要边界条件。     

道歉在信任修复中的作用:来自元分析的证据

采用元分析方法对道歉的信任修复效果进行探讨。通过中英文献检索,共有18篇文献36个独立样本符合元分析标准(N=4731)。元分析的结果表明,道歉在信任修复中起到一定促进作用,呈中等效应量(d=0.44)。调节效应检验发现,信任违背类型的调节作用显著,相比于诚实型信任违背,道歉对能力型信任违背有较好的修复效果。此外,控制组设置对道歉的信任修复效果具有显著的调节作用,以沉默为控制组的信任修复效果优于以否认为控制组的信任修复效果。信任类型、道歉所包含的成分以及测量工具的调节作用均不显著。     

多媒体学习中线索效应的元分析

作为多媒体学习中一种重要的指导性教学设计形式, 线索能否引导学习者的注意并促进学习效果, 目前结论尚不一致。研究运用元分析技术, 分别以保持测验、迁移测验的成绩作为学习效果的结果变量, 以线索区的注视时间、注视次数作为注意引导的结果变量, 探讨多媒体环境中的线索对学习效果和注意引导的影响, 并通过调节效应检验考察线索效应的边界条件。采用严格标准进行文献检索和筛选后, 共获取43篇符合元分析的文献。在保持测验成绩和迁移测验成绩上, 分别生成了44个(3910人)和41个(3906人)独立效应量; 在对线索区的注视时间和注视次数上, 分别生成了14个(938人)和11个(816人)独立效应量。结果发现, 线索的加入显著提高了保持测验成绩(g = 0.53)和迁移测验成绩(g = 0.36), 同时也增加了学习者对线索区的注视时间(g = 0.50)和注视次数(g = 0.70)。调节效应分析发现：在保持测验成绩上, 静态学习材料、陈述性知识、理工科条件下的线索效应分别高于动态学习材料、程序性知识和文科; 在迁移测验成绩上, 时空线索、静态学习材料、陈述性知识条件下的线索效应分别高于物理线索、动态学习材料和程序性知识; 而在眼动指标上, 线索对注意的引导主要受线索类型的调节, 物理线索条件下学习者对线索区的注视时间和注视次数均高于时空线索。结论认为, 线索的加入确实促进了学习者对学习材料的识记和理解效果, 同时也引导了学习者的注意分配; 但线索效应一定程度上受线索类型、学习材料动态性、知识类型、学科属性等因素的调节。未来研究需进一步考察线索效应的其他边界条件。     

Humor styles impact the relationship between symptoms of social anxiety and depression

Recent research suggests that examining humor styles may contribute to our understanding of clinical problems, such as risk and resiliency. The goal of the current study was to examine whether humor styles moderate the association between social anxiety and depressive symptoms in an unselected sample. Three-hundred and six participants (66% female) at a large Southern US university completed self-report measures of humor styles and symptoms of social anxiety and depression. Regression analyses suggested that affiliative and self-defeating humor styles individually moderated the relationship between social anxiety and depressive symptoms. Clinical implications regarding the monitoring of humor use as a means of understanding the maintenance of depressive symptoms among socially anxious individuals are discussed.     

Methods for addressing publication bias in school psychology journals: A descriptive review of meta-analyses from 1980 to 2019

Although meta-analyses are often used to inform practitioners and researchers, the resulting effect sizes can be artificially inflated due to publication bias. There are a number of methods to protect against, detect, and correct for publication bias. Currently, it is unknown to what extent scholars publishing meta-analyses within school psychology journals use these methods to address publication bias and whether more recently published meta-analyses more frequently utilize these methods. A historical review of every meta-analysis published to date within the most prominent school psychology journals (N = 10) revealed that 88 meta-analyses were published from 1980 to early 2019. Exactly half of them included grey literature, and 60% utilized methods to detect and correct for publication bias. The most common methods were visual analysis of a funnel plot, Orwin's failsafe N, Egger's regression, and the trim and fill procedure. None of these methods were used in more than 20% of the studies. About half of the studies incorporated one method, 20% incorporated two methods, 7% incorporated three methods, and none incorporated all four methods. These methods were most evident in studies published recently. Similar to other fields, the true estimates of effects from meta-analyses published in school psychology journals may not be available, and practitioners may be utilizing interventions that are, in fact, not as strong as believed. Practitioners, researchers employing meta-analysis techniques, education programs, and editors and peer reviewers in school psychology should continue to guard against publication bias using these methods.     

Telling Jokes That Disparage Social Groups: Effects on the Joke Teller's Stereotypes1

An experiment tested whether or not reciting disparaging humor about a disadvantaged group affects joke tellers' stereotypes of the group. In this experiment, we manipulated whether participants recited humor that disparaged Newfoundlanders, who are a relatively disadvantaged group in Canada, or nondisparaging humor. We then asked participants to complete a measure of their stereotypes and attitudes toward Newfoundlanders. Results indicated that participants who recited disparaging humor subsequently reported more negative stereotypes of Newfoundlanders than did participants who recited nondisparaging humor. Attitudes toward Newfoundlanders were not affected by the manipulation. Practical and theoretical implications of these findings are discussed.     

Say something nice: A meta-analytic review of peer reporting interventions

Peer reporting interventions (i.e., Positive Peer Reporting and tootling) are commonly used peer-mediated interventions in schools. These interventions involve training students to make reports about peers' prosocial behaviors, whether in oral or written form. Although peer reporting interventions have been included in meta-analyses of group contingencies, this study is the first meta-analytic review of single-case research focusing exclusively on peer reporting interventions. The literature search and application of inclusion criteria yielded 21 studies examining the impact of a peer reporting intervention on student behavior compared to baseline conditions. All studies used single-case experimental designs including at least three demonstrations of an effect and at least three data points per phase. Several aspects of studies, participants, and interventions were coded. Log response ratios and Tau were calculated as effect size estimates. Effect size estimates were synthesized in a multi-level meta-analysis with random effects for (a) studies and (b) cases within studies. Overall results indicated peer reporting interventions had a non-zero and positive impact on student outcomes. This was also true when data were subset by outcome (i.e., disruptive behavior, academically engaged behavior, and social behavior). Results were suggestive of more between- than within-study variability. Moderator analyses were conducted to identify aspects of studies, participants, or peer reporting interventions associated with differential effectiveness. Moderator analyses suggested published studies were associated with higher effect sizes than unpublished studies (i.e., theses/dissertations). This meta-analysis suggests peer reporting interventions are effective in improving student behavior compared to baseline conditions. Implications and directions for future investigation are discussed.     

Peer Leadership in Sport: Relationships among Personal Characteristics,Leader Behaviors,and Team Outcomes

Abstract

The present study comprised two meta-analyses of published studies that used the Profile of Mood States (POMS) to investigate relationships between mood and athletic achievement (n = 13) and between mood and performance outcome (n = 16). Results showed that effect sizes (ESs) for the level of achievement metaanalysis were minimal (Weighted Mean ES = .10, SD = .07), a finding consistent with a previous meta-analysis by Rowley, Landers, Kyllo, and Etnier (1995). Larger effects were found for the performance outcome meta-analysis (Weighted Mean ES = .31, SD = .12). Effects were moderate for vigor, confusion, and depression, small for anger and tension, and very small for fatigue. All effects were in the direction predicted by Morgan's (1985) Mental Health Model. Effects were larger in sports of short duration, in sports involving open skills, and where performance was judged using self-referenced criteria. Findings suggest that the POMS has utility in the prediction of performance outcome but not in the prediction of level of achievement.     

Humor styles and personality: A meta‐analysis of the relation between humor styles and the Big Five personality traits

This research summarizes the knowledge generated in social psychology and positive psychology about the relationship between humor styles, personality and wellbeing. Specifically, a meta‐analysis was performed with the results of 15 studies on humor styles measured by the Humor Styles Questionnaire (Martin, Puhlik‐Doris, Larsen, Gray & Weir, 2003) in correlation with the personality traits measured by the Big Five Personality model (measured with different scales). Following the steps presented by Rosenthal (1991) for meta‐analysis in the case of correlational research, we calculated the total mean r as an indicator of effect size. Results show that affiliative humor has a strong and homogeneous relation to neuroticism and extraversion. The homogeneity and heterogeneity found between variables and possible explanations are discussed in the conclusion.     

Self-face advantage over familiar and unfamiliar faces: A three-level meta-analytic approach

Despite the increasing number of researchers interested in self-face, so far, no study has summarized the behavioral findings that contribute to the debate on self-face advantage. Most studies have focused on neural correlates of the self, although functional uniqueness can also be considered an important criterion for determining whether a stimulus is unique. The present meta-analysis systematically compared reaction time (RT) responses for self-face with other face identities across 54 studies. Different moderator factors were tested: familiarity, identity, head angle, laterality, and culture. We used a three-level meta-analytic approach, which is the best approach to account for the dependency of effect sizes. Results showed a significant (Hedges’s g_av = ?0.298) effect size, indicating faster RT for self-face than for other faces in general. Except for culture, none of the moderators employed significantly impacted on the main effect. Regarding culture, results showed that participants from Western cultures tend to respond faster to their own face than to other people’s faces, while for participants from Eastern cultures, the effect was not significant. In summary, our results indicate that the self-face benefits from an advantage in terms of reaction time and may be considered a unique stimulus. Implications and limitations of the results are discussed.     

The nature and severity of cognitive impairment associated with adjuvant chemotherapy in women with breast cancer: a meta-analysis of the current literature

OBJECTIVE: Several studies have identified that adjuvant chemotherapy for breast cancer is associated with cognitive impairment; however, the magnitude of this impairment is unclear. This study assessed the severity and nature of cognitive impairment associated with adjuvant chemotherapy by conducting a meta-analysis of the published literature to date. METHOD: Six studies (five cross-sectional and one prospective) meeting the inclusion criteria provided a total of 208 breast cancer patients who had undergone adjuvant chemotherapy, 122 control participants and 122 effect sizes (Cohen's d) falling into six cognitive domains. First, the mean of all the effect sizes within each cognitive domain was calculated (separately for cross-sectional and prospective studies); second, a mean effect size was calculated for all of the effect sizes in each cross-sectional study; and third, regression analyses were conducted to determine any relationships between effect size for each study and four different variables. RESULTS: For the cross-sectional studies, each of the cognitive domains assessed (besides attention) showed small to moderate effect sizes (-0.18 to -0.51). The effect sizes for each study were small to moderate (-0.07 to -0.50) and regression analysis detected a significant negative logarithmic relationship (R2 = .63) between study effect size and the time since last receiving chemotherapy. For the prospective study, effect sizes ranged from small to large (0.11-1.09) and indicated improvements in cognitive function from the beginning of chemotherapy treatment to 3 weeks and even 1 year following treatment. CONCLUSION: This meta-analysis suggests that cognitive impairment occurs reliably in women who have undergone adjuvant chemotherapy for breast cancer but that the magnitude of this impairment depends on the type of design that was used (i.e., cross-sectional or prospective). Thus, more prospective studies are required before definite conclusions about the effects of adjuvant chemotherapy on cognition can be made.     

Rumination and dysphoria: The buffering role of adaptive forms of humor

The current study examines the effects of rumination and humor on individuals’ dysphoria level. Measures of humor (affiliative and self-enhancing), rumination, and depressive symptoms were completed by 303 undergraduate students. Consistent with our hypothesis, both affiliative humor and rumination independently accounted for variance in dysphoria levels. In addition, self-enhancing humor and rumination were independently associated with dysphoria. Moreover, significant interactions between affiliative humor and rumination, and self-enhancing humor and rumination, on dysphoria also emerged. Results indicated that among individuals with high rumination, those with high affiliative and/or self-enhancing humor had significantly lower levels of dysphoria than individuals with low affiliative and/or self-enhancing humor. The combination of low affiliative and/or self-enhancing humor and high rumination led to substantially higher levels of dysphoria than any other combination. Implications for psychotherapy and research in this area are discussed.     

The heritability of antisocial behavior: A meta-analysis of twin and adoption studies

In this paper, we describe a quantitative summary of 12 twin (n=3795 twin pairs and 3 adoption studies=338 adoptees) published since 1975 which provided 21 estimates of the heritability of antisocial behavior. Medium to large effect sizes were found for genetic influences across studies, with approximately 50% of the variance in measures of antisocial behavior attributable to genetic effects. Although effect sizes did not vary across different definitions of antisocial behavior (criminality, aggression, or antisocial personality), significantly larger estimates of genetic effect were found for severe manifestations of antisocial behavior. The importance of severity was further underscored by the significantly larger effects obtained in studies using clinic-referred samples compared to the effects obtained in studies using volunteer samples. Demographic characteristics of the samples did not influence effect sizes, although studies using more stringent methodology tended to find larger effects. These results must be interpreted in light of the small literature that was suitable for the meta-analysis due to numerous methodological limitations in existing studies.
