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.     

Does parochial cooperation exist in childhood and adolescence? A meta-analysis

Although previous meta-analytic evidence supports the existence of parochialism in cooperation among adults, the extent to which children and adolescents are more willing to incur a personal cost to benefit ingroups, compared to outgroups, is not yet clear. We provide the first meta-analysis on the existence and magnitude of parochialism in cooperation among pre-adults. Based on 20 experimental economics studies (k = 69, N = 5268, age = 3–19, 12 countries, published 2008–2019), a multilevel meta-analytic model revealed a small overall effect size indicating that children and adolescents were more cooperative towards ingroups (d = 0.22, 95% CI [0.07, 0.38]). A series of single-moderator analyses tested for the following conditions: participant age and sex; game type ([mini-]dictator game, prisoner's dilemma, public goods dilemma, trust game, ultimatum game); outcome interdependence; membership manipulation (between- vs. within-subjects); group type (natural vs. experimental); reward type (monetary vs. non-monetary); and country of the participant. Parochial cooperation did not vary with participants' age. Parochialism was larger in non-interdependent (dictator-type) compared to interdependent (bargaining and social dilemma) games. There were no moderating effects of group type, membership manipulation or reward type. To provide more data on how parochialism develops, primary studies should report age ranges more precisely and use more restricted age groups.     

Does matter really matter? Computer simulations,experiments, and materiality

A number of recent discussions comparing computer simulation and traditional experimentation have focused on the significance of “materiality.” I challenge several claims emerging from this work and suggest that computer simulation studies are material experiments in a straightforward sense. After discussing some of the implications of this material status for the epistemology of computer simulation, I consider the extent to which materiality (in a particular sense) is important when it comes to making justified inferences about target systems on the basis of experimental results.     

Self-forgiveness and well-being: Does divine forgiveness matter?

ABSTRACT

A reliable association exists between self-forgiveness and well-being. But self-forgiveness and its correlates will not be fully understood without considering forgiveness by God or divine forgiveness, especially in light of the fact that the majority of the population identifies as religious. This study therefore examined the role of divine forgiveness in understanding the association between self-forgiveness and well-being using data collected from 435 young adults. Because well-being is not the absence of distress, this study examined whether self-forgiveness and divine forgiveness relate to psychological well-being and distress in the same way. Self-forgiveness and divine forgiveness were independently related to psychological well-being and distress even with religiosity statistically controlled. Divine forgiveness also moderated the relationship between self-forgiveness and psychological distress in that perceived forgiveness by God was associated with fewer depressive symptoms at lower but not higher levels of self-forgiveness. The implications for future research are outlined.     

Does youth psychotherapy improve academically related outcomes? A meta-analysis

To better understand the impact of psychotherapy on youth academic performance, the authors located and examined 83 studies of youth psychotherapy that contained 102 treatment comparisons. Results revealed a d = 0.46 overall effect size, with a d = 0.50 effect size for mental health outcomes, and a d = 0.38 effect size for academically related outcomes. Academically related outcomes were further categorized into teacher-rated classroom behavior (d = 0.26), academic achievement (d = 0.36), environmentally related outcomes (d = 0.26), and self-reported academically related outcomes (d = 0.59). Each of these effect sizes differed significantly from zero, and the 4 academically related categories were homogeneous. Participant racial and ethnic diversity and age were explored as moderators. The results point to psychotherapy benefiting student academics, regardless of age. Ethnically diverse participant groups in the studies fared better academically than did nondiverse groups. Implications discussed include counseling psychologists maintaining a holistic view of youth and of working more closely with educators.     

Does lack of control lead to conspiracy beliefs? A meta-analysis

Perceived lack of control is widely believed to motivate, at least partly, belief in conspiracy theories. We question the theoretical foundations of this belief and meta-analyze existing published and unpublished studies to assess the overall effect of lack of control on conspiracy beliefs. The overall effect was small and not statistically significant (d = −0.05), and was not moderated by comparison group (baseline vs. control affirmation), type of manipulation used to threaten control, inclusion of a manipulation check, or sample type. However, the predicted effect of control was more likely to be observed when beliefs were measured in terms of specific conspiracy theories, rather than as general or abstract claims. Overall, the present studies to date offer limited support for the hypothesis that conspiracy beliefs arise as a compensatory control.     

Does intra-individual variability in narration matter and for what?

Building on calls to examine intra-individual variability in personality, we examined such variability in narrative. In Study 1, participants (n = 553) provided three narratives (either self-defining, turning point, transgression, low point, or trauma memories; n = 1659 narratives). Narratives were coded for coherence, autobiographical reasoning, resolution, and emotional expression. Variability was highest for resolution, lowest for coherence, and was related to well-being, depending on narrative feature and event type. In Study 2, participants (n = 103) engaged in a ‘narrative recognition’ task to see if they could identify which narratives came from the same individual. Recognizability was substantial, but not related to variability or well-being. Results showcase the importance of addressing intra-individual variability by narrative feature and event type.     

Who should rule? Does personality matter?

The study of leadership and personality has a long and controversial history. A review of trends and empirical research on relations between personality characteristics and leadership is presented. It is concluded that fragmentation and a narrow focus have been characteristic of most empirical research on leadership personality. The total space encompassing leadership issues has been compartmentalized into subareas such as leader traits, behaviour styles, and the situational view. It is argued that leadership is a multifaceted phenomenon that cannot be captured by focusing on a small number of variables. A holistic approach attempting to cover a range of traits so as to discern more complex trait patterns in relation to kinds of leader behaviour in different organizational settings is needed to gain an in-depth insight into the complexity of leader behaviour and leader effectiveness. Fragmentation of individual functioning needs to be reduced. Research should also focus on the dynamics of the relationship between leader characteristics and leader behaviour in different social settings. © 1997 John Wiley & Sons, Ltd.     

The KiVa antibullying curriculum and outcome: Does fidelity matter?

Research on school-based prevention suggests that the success of prevention programs depends on whether they are implemented as intended. In antibullying program evaluations, however, limited attention has been paid to implementation fidelity. The present study fills in this gap by examining the link between the implementation of the KiVa antibullying program and outcome. With a large sample of 7413 students (7–12 years) from 417 classrooms within 76 elementary schools, we tested whether the degree of implementation of the student lessons in the KiVa curriculum was related to the effectiveness of the program in reducing bullying problems in classrooms. Results of multilevel structural equation modeling revealed that after nine months of implementation, lesson adherence as well as lesson preparation time (but not duration of lessons) were associated with reductions in victimization at the classroom level. No statistically significant effects, however, were found for classroom-level bullying. The different outcomes for victimization and bullying as well as the importance of documenting program fidelity are discussed.     

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.     

Does personality matter in exercise participation?

This research extends previous work by demonstrating how the relationships between social cognition and exercise are influenced by different personality types. The theory of planned behaviour forms the basis of our theoretical model, and the Big Five personality framework was used to determine personality types. Data were collected from a quota sample of 512 Malaysian adults. The results suggest that an individual's personality can prevent him or her from exercising. For example, an extrovert is likely to be driven by affect and self‐confidence in their capability to exercise, and thus are more likely to participate in exercise. Those who are more conscientious (and less neurotic) feel more in control and thus possess a greater ability to exercise in comparison with their less conscientious and more neurotic counterparts. Our findings demonstrate the importance of considering personality factors in exercise research and caution us about underestimating the relationship between perceived control, attitude and its potential behavioural outcomes that could lead to a misinterpretation of its true impact. Our core contribution lies in identifying the underlying causes of social cognition differences in a moderating capacity, which has potential to yield important theoretical and practical implications. This study sets the ground for social marketers to improve their understanding of exercise behaviour and, in turn, consumer welfare. Ultimately, they could be in a better position to develop effective health intervention and educational programmes. Copyright © 2013 John Wiley & Sons, Ltd.     

Links between television exposure and toddler dysregulation: Does culture matter?

Television exposure in early childhood has increased, with concerns raised regarding adverse effects on social-emotional development, and emerging self-regulation in particular. The present study addressed television exposure (i.e., amount of time watching TV) and its associations with toddler behavioral/emotional dysregulation, examining potential differences across 14 cultures. The sample consisted of an average of 60 toddlers from each of the 14 countries from the Joint Effort Toddler Temperament Consortium (JETTC; Gartstein & Putnam, 2018). Analyses were conducted relying on the multi-level modeling framework (MLM), accounting for between- and within-culture variability, and examining the extent to which TV exposure contributions were universal vs. variable across sites. Effects of time watching TV were evaluated in relation to temperament reactivity and regulation, as well as measures of emotional reactivity, attention difficulties, and aggression. Results indicated that more time spent watching TV was associated with higher ratings on Negative Emotionality, emotional reactivity, aggression, and attention problems, as well as lower levels of soothability. However, links between TV exposure and both attention problems and soothability varied significantly between cultures. Taken together, results demonstrate that increased time spent watching television was generally associated with dysregulation, although effects were not consistently uniform, but rather varied as a function of culturally-dependent contextual factors.     

Fathers,daughters, and self-objectification: Does bonding style matter?

As women are exposed to objectification and the “male gaze,” they self-objectify, which predicts negative psychological outcomes. Given the centrality of the “male gaze,” positive father/child relationships may have a buffering effect. In this study, women (N = 447) completed a survey measuring paternal bonding (care and overprotection), self-objectification, negative eating attitudes, and depression. Women were categorized into four groups based on bonding style. Analyses indicated an interaction such that women who reported high care and low overprotection reported the fewest negative eating attitudes. A path model was tested for each group. The fit of the high care/high overprotection group's model significantly differed from that of the high care/low overprotection group. The relationships between body surveillance and shame as well as between shame and negative eating attitudes were stronger in the former group. These findings suggest that caring but overprotective fathers may exacerbate the negative effects of body surveillance and shame.     

Psychological contract breach and workplace deviance: Does emotional intelligence matter?

This study investigated the influence of emotional intelligence on the relationship between psychological contract breach and workplace deviance with feelings of violation. The participants were 232 employees of a Nigerian public sector organisation (125 males and 107 females). The employees completed measures of workplace deviance, psychological contract breach, feelings of violation, and emotional intelligence. Results of the moderated hierarchical multiple regression analysis indicated that psychological contract breach was positively related to feelings of violation and workplace deviance. Emotional intelligence significantly buffered the negative effect of psychological contract breach on feelings of violation and workplace deviance. This implies that emotionally intelligent employees who perceived contract breach are less likely to experience feelings of violation and engage in workplace deviance. Emotional regulation appears to reliably moderate between breach-outcome relationships.     

Cognitive dissonance and self-monitoring: A matter of context?

In Study 1, high and low self-monitors wrote counterattitudinal essays. For some, we made it salient that they would be endorsing an opinion contrary to that of their peers. For others, no context was provided. Post-essay attitudes of high, relative to low, self-monitors were more consistent with essay topic after opposing peers. Post-essay attitudes of low and high self-monitors did not differ significantly in the no-context condition. In Study 2, high and low self-monitors wrote counterattitudinal essays in the context of opposing either their peers' beliefs or their own values. Post-essay attitudes of low, relative to high, self-monitors tended to conform more to their essays when they believed that they had written in opposition to their values. When writing in opposition to their peers, however, post-essay attitudes of high and low self-monitors did not differ significantly. We discuss the results in terms of the role that self-concept plays in the initiation of dissonance processesStudy 2 is based on the senior honors thesis of the second author conducted under the supervision of the first author, and both studies were supported by a Faculty Research Grant from Union College to the first author. We would like to thank Alice M. Isen, Mark Snyder, Hugh Foley, and an anonymous reviewer for their valuable comments on an earlier version of this article, and Nicole Audette, Amy Goldstein, Suzanne Shaker, and Courtney Shapiro for their assistance in collecting and analyzing data.     

Does dose of early intervention matter for preschoolers with externalizing behavior problems? A pilot randomized trial comparing intensive summer programming to school consultation

The goals of this study were to (a) isolate the ideal length (i.e., 4 or 8 weeks) of the Summer Treatment Program for Kindergarteners (STP-PreK) for improving school readiness and kindergarten success outcomes of preschool children with externalizing behavior problems (EBPs) during the transition to kindergarten; and (b) compare the STP-PreK model to a more standard approach in school settings (i.e., behavioral school consultation). Forty-five preschool children (82% boys; Mage = 5.16 years; 93% Hispanic/Latino background) were randomized to one of three intervention conditions: 1) 8-week STP-PreK (8W); 2) 4-week STP-PreK (4W); or 3) school year behavioral consultation (SC). Both STP-PreK groups included an 8-week parent training component. Baseline, post-intervention, and 6-month follow-up data were collected on children's school readiness and kindergarten success outcomes including parent, teacher, and objective assessment measures. Analyses using linear mixed models indicated that children's behavioral, academic, social-emotional, and self-regulation functioning significantly improved across groups. Few significant differences were found between children receiving the 4W and 8W programs, suggesting that both programs have the potential to prepare preschool children with EBP for the transition to school. Both 4W and 8W groups experienced greater initial growth across time in most domains compared to children in the SC group. However, by the end of the kindergarten year, children in the SC group caught up to children in both 4W and 8W groups on most domains. Overall, these findings suggest that all three intervention doses are effective in improving kindergarten year functioning, with some important considerations for intervention timing in preparation for the transition to elementary school. Clinical implications for school personnel are discussed.     

Does changing behavioral intentions engender behavior change? A meta-analysis of the experimental evidence

Numerous theories in social and health psychology assume that intentions cause behaviors. However, most tests of the intention- behavior relation involve correlational studies that preclude causal inferences. In order to determine whether changes in behavioral intention engender behavior change, participants should be assigned randomly to a treatment that significantly increases the strength of respective intentions relative to a control condition, and differences in subsequent behavior should be compared. The present research obtained 47 experimental tests of intention-behavior relations that satisfied these criteria. Meta-analysis showed that a medium-to-large change in intention (d = 0.66) leads to a small-to-medium change in behavior (d = 0.36). The review also identified several conceptual factors, methodological features, and intervention characteristics that moderate intention-behavior consistency.
