Are memory self-efficacy and memory performance related? A meta-analysis.

The association between memory self-efficacy (MSE) and memory performance is highly documented in the literature. However, previous studies have produced inconsistent results, and there is no consensus on the existence of a significant link between these two variables. In order to evaluate whether or not the effect size of the MSE–memory performance relationship in healthy adults is significant and to test several theory-driven moderators, we conducted a meta-analysis of published and unpublished studies. A random-effects model analysis of data from 107 relevant studies (673 effect sizes) indicated a low but significant weighted mean correlation between MSE and memory performance, r = .15, 95% CI [.13, .17]. In addition, the mean effect size was significantly moderated by the way MSE was assessed. Memory performance was more strongly related to concurrent MSE (perceived current ability to perform a given task) than it was to global MSE (perceived usual memory ability in general). Furthermore, we found marginally larger MSE–memory performance correlations when the memory situations used to assess MSE involved familiar stimuli. No effect of the method used to assess global MSE or domain MSE (memory rating vs. performance predictions) was found. The results also show that the resource demands of the memory tasks have a moderator effect, as the MSE–performance correlation is larger with free-recall and cued-recall tasks than it is with recognition tasks. Limitations (generalization issues, moderators not considered) and implications for future research are discussed. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

When do gestures communicate? A meta-analysis.

Do the gestures that speakers produce while talking significantly benefit listeners' comprehension of the message? This question has been the topic of many research studies over the previous 35 years, and there has been little consensus. The present meta-analysis examined the effect sizes from 63 samples in which listeners' understanding of a message was compared when speech was presented alone with when speech was presented with gestures. It was found that across samples, gestures do provide a significant, moderate benefit to communication. Furthermore, the magnitude of this effect is moderated by 3 factors. First, effects of gesture differ as a function of gesture topic, such that gestures that depict motor actions are more communicative than those that depict abstract topics. Second, effects of gesture on communication are larger when the gestures are not completely redundant with the accompanying speech; effects are smaller when there is more overlap between the information conveyed in the 2 modalities. Third, the size of the effect of gesture is dependent on the age of the listeners, such that children benefit more from gestures than do adults. Remaining questions for future research are highlighted. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Does human capital matter? A meta-analysis of the relationship between human capital and firm performance.

Theory at both the micro and macro level predicts that investments in superior human capital generate better firm-level performance. However, human capital takes time and money to develop or acquire, which potentially offsets its positive benefits. Indeed, extant tests appear equivocal regarding its impact. To clarify what is known, we meta-analyzed effects drawn from 66 studies of the human capital–firm performance relationship and investigated 3 moderators suggested by resource-based theory. We found that human capital relates strongly to performance, especially when the human capital in question is not readily tradable in labor markets and when researchers use operational performance measures that are not subject to profit appropriation. Our results suggest that managers should invest in programs that increase and retain firm-specific human capital. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Does pretreatment severity moderate the efficacy of psychological treatment of adult outpatient depression? A meta-analysis.

Objective: It is widely believed that psychological treatment has little effect on more severely depressed patients. This study assessed whether pretreatment severity moderates psychological treatment outcome relative to controls by means of meta-analyses. Method: We included 132 studies (10,134 participants) from a database of studies (www.evidencebasedpsychotherapies.org) in which the effects of psychological treatment on adult outpatients with a depressive disorder or an elevated level of depressive symptoms were compared with a control condition in a randomized controlled trial. Two raters independently extracted outcome data and rated study characteristics. We conducted metaregression analyses assessing whether mean pretreatment depression scores predicted psychological treatment versus control condition posttreatment effect size and subgroup analyses summarizing the results of studies reporting within-study analyses of depression severity and psychological treatment outcome. Results: Psychological treatment was found to be consistently superior to control conditions (d = 0.40–0.88). We found no indication that pretreatment mean depression scores predicted psychological treatment versus control condition posttreatment effect size, even after adjusting for relevant study characteristics. However, among the smaller subset of studies that reported within-study severity analyses, posttreatment effect sizes were higher for high-severity patients (d = 0.63) than for low-severity patients (d = 0.22) when psychological treatment was efficacious relative to a more stringent control. Conclusion: Contrary to conventional wisdom, our findings suggest that when compared with control conditions, psychological treatment might be more efficacious for high-severity than for low-severity patients. Because the number of studies reporting within-study severity analyses is small, we recommend that future studies routinely report tests for Severity × Treatment interactions.

Are leader stereotypes masculine? A meta-analysis of three research paradigms.

This meta-analysis examined the extent to which stereotypes of leaders are culturally masculine. The primary studies fit into 1 of 3 paradigms: (a) In Schein's (1973) think manager–think male paradigm, 40 studies with 51 effect sizes compared the similarity of male and leader stereotypes and the similarity of female and leader stereotypes; (b) in Powell and Butterfield's (1979) agency–communion paradigm, 22 studies with 47 effect sizes compared stereotypes of leaders' agency and communion; and (c) in Shinar's (1975) masculinity–femininity paradigm, 7 studies with 101 effect sizes represented stereotypes of leadership-related occupations on a single masculinity–femininity dimension. Analyses implemented appropriate random and mixed effects models. All 3 paradigms demonstrated overall masculinity of leader stereotypes: (a) In the think manager–think male paradigm, intraclass correlation = .25 for the women–leaders similarity and intraclass correlation = .62 for the men–leaders similarity; (b) in the agency–communion paradigm, g = 1.55, indicating greater agency than communion; and (c) in the masculinity–femininity paradigm, g = 0.92, indicating greater masculinity than the androgynous scale midpoint. Subgroup and meta-regression analyses indicated that this masculine construal of leadership has decreased over time and was greater for male than female research participants. In addition, stereotypes portrayed leaders as less masculine in educational organizations than in other domains and in moderate- than in high-status leader roles. This article considers the relation of these findings to Eagly and Karau's (2002) role congruity theory, which proposed contextual influences on the incongruity between stereotypes of women and leaders. The implications for prejudice against women leaders are also considered. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Why do lie-catchers fail? A lens model meta-analysis of human lie judgments.

Decades of research has shown that people are poor at detecting lies. Two explanations for this finding have been proposed. First, it has been suggested that lie detection is inaccurate because people rely on invalid cues when judging deception. Second, it has been suggested that lack of valid cues to deception limits accuracy. A series of 4 meta-analyses tested these hypotheses with the framework of Brunswik's (1952) lens model. Meta-Analysis 1 investigated perceived cues to deception by correlating 66 behavioral cues in 153 samples with deception judgments. People strongly associate deception with impressions of incompetence (r = .59) and ambivalence (r = .49). Contrary to self-reports, eye contact is only weakly correlated with deception judgments (r = ?.15). Cues to perceived deception were then compared with cues to actual deception. The results show a substantial covariation between the 2 sets of cues (r = .59 in Meta-Analysis 2, r = .72 in Meta-Analysis 3). Finally, in Meta-Analysis 4, a lens model analysis revealed a very strong matching between behaviorally based predictions of deception and behaviorally based predictions of perceived deception. In conclusion, contrary to previous assumptions, people rarely rely on the wrong cues. Instead, limitations in lie detection accuracy are mainly attributable to weaknesses in behavioral cues to deception. The results suggest that intuitive notions about deception are more accurate than explicit knowledge and that lie detection is more readily improved by increasing behavioral differences between liars and truth tellers than by informing lie-catchers of valid cues to deception.

Does violence beget violence? A critical examination of the literature.

Critically examines the "violence breeds violence" hypothesis broadly defined. Organized into seven sections, the literature review includes (a) the abuse breeds abuse hypothesis; (b) reports of small numbers of violent/homicidal offenders; (c) studies examining the relationship of abuse and neglect to delinquency; (d) to violent behavior, and (e) to aggressive behavior in infants and young children; (f) abuse, withdrawal, and self-destructive behavior; and (g) studies of the impact of witnessing or observing violent behavior. A detailed discussion of methodological considerations and shortcomings precedes the review. The author concludes that existing knowledge of the long-term consequences of abusive home environments is limited and suggests that conclusions about the strength of the cycle of violence be tempered by the dearth of convincing empirical evidence. Recommendations are made for further research. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

A meta-analysis of work–family conflict and various outcomes with a special emphasis on cross-domain versus matching-domain relations.

A literature review of studies analyzing work–family conflict and its consequences was conducted, and 427 effect sizes were analyzed meta-analytically. Work–family conflict was analyzed bidirectionally in terms of work interference with family (WIF) and family interference with work (FIW). We assessed 3 categories of potential outcomes: work-related outcomes, family-related outcomes, and domain-unspecific outcomes. Results show that WIF and FIW are consistently related to all 3 types of outcomes. Both types of interrole conflict showed stronger relationships to same-domain outcomes than to cross-domain outcomes. Thus, WIF was more strongly associated with work-related than with family-related outcomes, and FIW was more strongly associated with family-related than with work-related outcomes. In moderator analyses, parenthood could not explain variability in effect sizes. However, time spent at work did moderate the relationships between WIF and family-related outcomes, as well as FIW and domain-unspecific outcomes.

Attachment theory: A “secure base” for psychotherapy integration.

Attachment theory is well positioned to serve as a foundation for assimilative psychotherapy integration. It has an exceptionally strong empirical base and provides a life span developmental framework often absent in current treatment models. Attachment theory focuses on the need for proximity to a sensitive caregiver in childhood who provides a sense of security and a safe base from which to explore. Affect regulation and relational behavior in later life are greatly affected by the vicissitudes of attachment relationships, with significant implications for psychopathology and psychotherapy. Attachment theory should help bridge the current gap between researchers and practitioners because it underscores the centrality of relationship in the therapeutic process but possesses a long tradition of empiricism. I propose three criteria that a foundational theory requires at this time and suggest that attachment theory satisfies them with its breadth of explanatory power, strong research base, and potential for integration with a wide array of other methods.

Does stress exacerbate parental differential treatment of siblings? A pattern-analytic approach.

To develop a typology based on family members' perspectives on parental differential treatment of siblings, data from mothers, fathers, firstborn adolescent siblings (M?=?15 years), and second-born adolescent siblings (M?=?12.5 years) from 187 families were submitted to cluster analysis. A 4-cluster solution based on the convergence or divergence of reports and the levels of parental differential treatment was identified and replicated: convergent/all below average (n?=?94), convergent/all above average (n?=?48), divergent/all below average except older sibling (n?=?20), and divergent/all above average except mother (n?=?25). Analyses revealed cluster differences in family structure (e.g., sex of siblings, age spacing) and in parents' perceived levels of stress across several domains (e.g., work, marriage, and individual mental health).

Are you interested? A meta-analysis of relations between vocational interests and employee performance and turnover.

A common belief among researchers is that vocational interests have limited value for personnel selection. However, no comprehensive quantitative summaries of interests validity research have been conducted to substantiate claims for or against the use of interests. To help address this gap, we conducted a meta-analysis of relations between interests and employee performance and turnover using data from 74 studies and 141 independent samples. Overall validity estimates (corrected for measurement error in the criterion but not for range restriction) for single interest scales were .14 for job performance, .26 for training performance, –.19 for turnover intentions, and –.15 for actual turnover. Several factors appeared to moderate interest–criterion relations. For example, validity estimates were larger when interests were theoretically relevant to the work performed in the target job. The type of interest scale also moderated validity, such that corrected validities were larger for scales designed to assess interests relevant to a particular job or vocation (e.g., .23 for job performance) than for scales designed to assess a single, job-relevant realistic, investigative, artistic, social, enterprising, or conventional (i.e., RIASEC) interest (.10) or a basic interest (.11). Finally, validity estimates were largest when studies used multiple interests for prediction, either by using a single job or vocation focused scale (which tend to tap multiple interests) or by using a regression-weighted composite of several RIASEC or basic interest scales. Overall, the results suggest that vocational interests may hold more promise for predicting employee performance and turnover than researchers may have thought.

Work and nonwork outcomes of workplace incivility: Does family support help?

This study extended incivility research beyond the confines of the workplace by exploring the relationships between incivility, work-to-family conflict and family support. Data collected from 180 employees from various organizations in Singapore showed that incivility is not a rare phenomenon in Asian cultures. Employees experienced more incivility from superiors than coworkers or subordinates, and these experiences were related to different outcomes. Coworker-initiated incivility was associated with decreased coworker satisfaction, increased perceptions of unfair treatment, and increased depression. On the other hand, superior-initiated incivility was associated with decreased supervisor satisfaction and increased work-to-family conflict. Results also revealed that employees with high family support showed stronger relationships between workplace incivility and negative outcomes, compared with employees with low family support.

Does attention-deficit/hyperactivity disorder have a dimensional latent structure? A taxometric analysis.

An understanding of the latent structure of attention-deficit/hyperactivity disorder (ADHD) is essential for developing causal models of this disorder. Although some researchers have presumed that ADHD is dimensional and others have assumed that it is taxonic, there has been relatively little research directly examining the latent structure of ADHD. The authors conducted a set of taxometric analyses using data from the NICHD Study of Early Child Care and Youth Development (ns between 667 and 1,078). The results revealed a dimensional latent structure across a variety of different analyses and sets of indicators for inattention, hyperactivity/impulsivity, and ADHD. Furthermore, analyses of correlations with associated features indicated that dimensional models demonstrated stronger validity coefficients with these criterion measures than dichotomous models. These findings jibe with recent research on the genetic basis of ADHD and with contemporary models of ADHD. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

How are visuospatial working memory, executive functioning, and spatial abilities related? A latent-variable analysis.

This study examined the relationships among visuospatial working memory (WM) executive functioning, and spatial abilities. One hundred sixty-seven participants performed visuospatial short-term memory (STM) and WM span tasks, executive functioning tasks, and a set of paper-and-pencil tests of spatial abilities that load on 3 correlated but distinguishable factors (Spatial Visualization, Spatial Relations, and Perceptual Speed). Confirmatory factor analysis results indicated that, in the visuospatial domain, processing-and-storage WM tasks and storage-oriented STM tasks equally implicate executive functioning and are not clearly distinguishable. These results provide a contrast with existing evidence from the verbal domain and support the proposal that the visuospatial sketchpad may be closely tied to the central executive. Further, structural equation modeling results supported the prediction that, whereas they all implicate some degree of visuospatial storage, the 3 spatial ability factors differ in the degree of executive involvement (highest for Spatial Visualization and lowest for Perceptual Speed). Such results highlight the usefulness of a WM perspective in characterizing the nature of cognitive abilities and, more generally, human intelligence.

What is so special about male adolescent sexual offending? A review and test of explanations through meta-analysis.

We tested special and general explanations of male adolescent sexual offending by conducting a meta-analysis of 59 independent studies comparing male adolescent sex offenders (n = 3,855) with male adolescent non-sex offenders (n = 13,393) on theoretically derived variables reflecting general delinquency risk factors (antisocial tendencies), childhood abuse, exposure to violence, family problems, interpersonal problems, sexuality, psychopathology, and cognitive abilities. The results did not support the notion that adolescent sexual offending can be parsimoniously explained as a simple manifestation of general antisocial tendencies. Adolescent sex offenders had much less extensive criminal histories, fewer antisocial peers, and fewer substance use problems compared with non-sex offenders. Special explanations suggesting a role for sexual abuse history, exposure to sexual violence, other abuse or neglect, social isolation, early exposure to sex or pornography, atypical sexual interests, anxiety, and low self-esteem received support. Explanations focusing on attitudes and beliefs about women or sexual offending, family communication problems or poor parent–child attachment, exposure to nonsexual violence, social incompetence, conventional sexual experience, and low intelligence were not supported. Ranked by effect size, the largest group difference was obtained for atypical sexual interests, followed by sexual abuse history, and, in turn, criminal history, antisocial associations, and substance abuse. We discuss the implications of the findings for theory development, as well as for the assessment, treatment, and prevention of adolescent sexual offending.

Therapist differences in cognitive–behavioral psychotherapy for generalized anxiety disorder: A pilot study.

Little is known about factors differentiating more and less effective therapists or the mechanisms through which therapists influence outcome. In the present study, the performance of a small sample of 4 therapists was compared in the context of delivering cognitive–behavioral psychotherapy (CBT) to 32 clients with generalized anxiety disorder. More effective therapists were characterized by higher observer-rated CBT competence, higher client outcome expectations and client treatment credibility assessments, and higher early treatment client ratings of therapeutic alliance quality. Higher early CBT competence was associated with higher client midtreatment outcome expectations, which in turn were associated with better posttreatment outcomes. Although these findings are preliminary given the small sample of therapists and clients, they suggest that the common factor of outcome expectations might be a mechanism through which the specific factor of psychotherapist competence exerts its influence on treatment outcome. The implications of these findings and directions for future research are discussed. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

A meta-analysis of performance on emotion recognition tasks in Parkinson’s disease.

Individuals with Parkinson’s disease (PD) have shown deficits in the ability to recognize emotion. However, these results have been inconsistent. In addition, questions remain about whether any deficit in PD is secondary to depression and broader cognitive impairments, and the effects of stimulus modality, task type, and specific emotion remain unclear. A meta-analysis of 34 comparisons, using data from 1,295 individual participants, was conducted to (a) provide a reliable estimate of the magnitude of the purported deficit in emotion recognition and (b) examine the influence of several potential moderators of emotion recognition abilities in PD. Results show a robust link between PD and specific deficits in recognizing emotion, from both the face and the voice (overall effect size g = 0.52). The deficit extends across stimulus modalities and task types and is particularly acute with respect to negative emotions. Although this deficit does not appear to be secondary to comorbid depression or visuospatial impairments, the potential role of working memory constraints warrants further investigation. We highlight the potential implications of these findings for communication abilities in PD. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Birth cohort differences in self-esteem, 1988–2008: A cross-temporal meta-analysis.

Three meta-analyses find increases over the generations in Rosenberg Self-Esteem scale (RSE) scores between 1988 and 2008 among American middle school (d = 0.78, n = 10,119), high school (d = 0.39, n = 16,669), and college students (d = 0.30, n = 28,918). The changes are consistent with an increasing emphasis on self-worth in American culture and, for high school students, with small increases in academic competence over time. College students' scores change only when the RSE is administered with a 4-point Likert scale with no midpoint. By 2008, a score of 40 (perfect self-esteem) was the modal response of college students, chosen by 18% of participants; 51% scored 35 or over. Given these shifts in responses, the possibility of revising the RSE is discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Rumination and cigarette smoking: A bad combination for depressive outcomes?

Ruminative coping has been shown to heighten the risk and severity of depression. The authors hypothesized that ruminators who smoke would experience greater depressive symptoms than ruminators who do not. The rationale is that, by heightening attentional focus, nicotine may increase ruminators' ability to focus on negative thoughts, augmenting depressed mood. Participants (N = 145) self-reported smoking status, rumination, and current and lifetime depressive symptoms, including depressed mood. Results showed that rumination accounted for a larger amount of variance in current and past depressed mood and severity of lifetime depressive symptoms among smokers than nonsmokers. Noncorrelational, experimental research should directly test whether nicotine worsens depressed mood among ruminative smokers. Such evidence would be surprising because it would contradict the assumption that nicotine dispels negative moods. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Does vocational overshadowing even exist? A test of the robustness of the vocational overshadowing bias.

Vocational overshadowing (P. M. Spengler, D. L. Blustein, & D. C. Strohmer, 1990 ) is a hypothesized underemphasis of clients' career concerns when more interesting, prestigious, or economically rewarding "personal" problems coexist. This study tested the robustness of the vocational overshadowing bias by using an expanded array of case material, by including practicing counseling psychologists (n?=?125) and clinical psychologists (n?=?121), and by assessing the moderating effects of clinician information processing and attitudinal characteristics. Clinical psychologists were more likely than counseling psychologists to underemphasize vocational concerns combined with severe noncareer problems. More complex thinking about career counseling and higher preference for working with career problems were associated with greater attention to clients' career concerns. However, no clear evidence was found for the vocational overshadowing bias by either equal or less severe noncareer problems. Implications of these findings for career counseling and clinical judgment research are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
