ETHNIC GROUP DIFFERENCES IN COGNITIVE ABILITY IN EMPLOYMENT AND EDUCATIONAL SETTINGS: A META-ANALYSIS

The cognitive ability levels of different ethnic groups have interested psychologists for over a century. Many narrative reviews of the empirical literature in the area focus on the Black-White differences, and the reviews conclude that the mean difference in cognitive ability ( g ) is approximately 1 standard deviation; that is, the generally accepted effect size is about 1.0. We conduct a meta-analytic review that suggests that the one standard deviation effect size accurately summarizes Black-White differences for college application tests (e.g., SAT) and overall analyses of tests of g for job applicants in corporate settings. However, the 1 standard deviation summary of group differences fails to capture many of the complexities in estimating ethnic group differences in employment settings. For example, our results indicate that job complexity, the use of within job versus across job study design, focus on applicant versus incumbent samples, and the exact construct of interest are important moderators of standardized group differences. In many instances, standardized group differences are less than 1 standard deviation. We conduct similar analyses for Hispanics, when possible, and note that Hispanic-White differences are somewhat less than Black-White differences.     

INCREASED ACCURACY FOR RANGE RESTRICTION CORRECTIONS: IMPLICATIONS FOR THE ROLE OF PERSONALITY AND GENERAL MENTAL ABILITY IN JOB AND TRAINING PERFORMANCE

A recently developed procedure produces substantial improvements in the accuracy of corrections for range restriction and reveals that predictive validities of employment selection methods are higher than previously thought. This study applied this procedure to meta‐analytic validities of 2 personality measures (Conscientiousness and Emotional Stability) and general cognitive ability measures. Results show that the increases in validity estimates are greater for cognitive ability than for personality, reducing the relative validity of personality. In addition, the incremental validity of these personality measures over that provided by cognitive ability is smaller than previously estimated. Path analyses based on the more accurate data reveal relatively smaller path coefficients from these personality traits to job and training performance. These findings have implications for theories of job performance and for the practical value in selection of personality measures relative to cognitive ability measures.     

ADAPTABILITY TO CHANGING TASK CONTEXTS: EFFECTS OF GENERAL COGNITIVE ABILITY, CONSCIENTIOUSNESS, AND OPENNESS TO EXPERIENCE

We examined the extent to which cognitive ability, Conscientiousness, and Openness to Experience predict decision-making performance prior to and after unforeseen changes in the task context. Seventy-three undergraduates made decisions on a series of 75 problems during a 3-hour computerized simulation. Unbeknownst to participants, the rules used in determining correct decisions changed after problems 25 and 50. Effects of the individual differences on decision-making performance became significantly stronger after the changes. Only cognitive ability explained variance in prechange performance. Individuals with higher cognitive ability made better decisions. After the change, the cognitive ability effect increased and the effects of Conscientiousness and Openness became statistically significant. As expected, those with high Openness made better decisions. Unexpectedly, those with low Conscientiousness made better decisions. Subsequent analyses revealed that this surprising effect for Conscientiousness was due to the traits reflecting dependability (i.e., order, dutiful-ness, deliberation) rather than volition (i.e., competence, achievement striving, self-discipline).     

海马结构、前额皮层或尾-壳核损毁对大鼠空间认知能力的影响

本研究的目的是探讨海马结构(HF)、前额皮层(PFC)和尾-壳核(CP)在大鼠空间认知加工中的作用。实验观察到HP或PFC损毁大鼠Morris迷宫学习或记忆作业成绩显著低于CP损毁组和控制组(CG);HF损毁大鼠主要采用与其它各组不同的“非图类”搜索策略。搜索策略的差异提示:HF和PFC在大鼠图认知加工系统中处于不同的功能层次,HF起相对重要的作用。CP几乎不影响大鼠空间认知能力,表现出哺乳类与鸟类同源结构的功能分化倾向。     

BRIEF REPORT: RELATIONSHIPS OF CIGARETTE SMOKING TO ACADEMIC ACHIEVEMENT,COGNITIVE ABILITIES,AND ATTITUDES TOWARD AUTHORITY

Published research has linked cigarette smoking with (1) inferior academic performance, (2) lower quantitative scholastic aptitude, and (3) negative attitude toward authority figures. Using data from 2315 freshmen (1368 males and 967 females), these three relationships were confirmed. Further- more, analyses of covariance clearly demonstrated that neither scholastic aptitude nor attitudes toward authority-although themselves related to academic performance would account for the relationship between cigarette smoking and grade-point average.     

IDENTITIES IN HARMONY: GENDER–WORK IDENTITY INTEGRATION MODERATES FRAME SWITCHING IN COGNITIVE PROCESSING

Professional women's identity integration—the perceived compatibility between work and gender identities—plays a role in how task or relationship information is processed. Seventy female business school students were primed with either their professional or their gender identity. Business women with higher identity integration showed an assimilation effect to the primed cue. Specifically, they showed higher task orientation than relationship orientation in a recognition task when primed with their professional identity, but less so when primed with their gender identity. Business women with lower identity integration showed a contrast effect to the primed cue: Their recognition reflected a task-relationship orientation opposite to the primed cue. We discuss the implications of these findings for understanding women's performance at work.     

REPORTED INCIDENCE RATES OF WORK-RELATED SEXUAL HARASSMENT IN THE UNITED STATES: USING META-ANALYSIS TO EXPLAIN REPORTED RATE DISPARITIES

This study presents a meta-analytic review of the incidence of sexual harassment in the U.S. The impact of 3 main moderator variables (type of survey used, sampling technique, and the type of work environment in which the study was conducted) on the reported incidence rate was estimated by cumulating incidence rates reported in the literature. Results show that directly querying the respondents about whether or not they experienced sexual harassment (vs. using questionnaires that listed behaviors believed to constitute sexual harassment), and employing probability-sampling techniques (vs. convenience sampling), led to substantially lower estimates of sexual harassment incidence. In addition, the results suggest that sexual harassment is more prevalent in organizations characterized by relatively large power differentials between organizational levels. Based on more than 86,000 respondents from 55 probability samples, on average, 58% of women report having experienced potentially harassing behaviors and 24% report having experienced sexual harassment at work.     

DEVELOPING EXECUTIVE LEADERS: THE RELATIVE CONTRIBUTION OF COGNITIVE ABILITY,PERSONALITY, AND THE ACCUMULATION OF WORK EXPERIENCE IN PREDICTING STRATEGIC THINKING COMPETENCY

We conceptually define and empirically investigate the accumulation of work experience—a concept that refers to the extent to which executives have amassed varied levels of roles and responsibilities (i.e., contributor, manager, lead strategist) in each of the key work activities that they have encountered over the course of their careers. In studying executives’ work experience accumulation, we consider key antecedents such as executives’ cognitive ability and personality traits, namely Extraversion and Openness to Experience, and examine the value of work experience accumulation on executives’ strategic thinking competency. Analyses of multisource data from 703 executives revealed 3 key findings: (a) accumulated work experience positively relates to executives’ strategic thinking competency after controlling for individual characteristics and other measures of work experience; (b) executives’ cognitive ability demonstrates the strongest and most positive relationship to executives’ strategic thinking competency; and (c) extraverted executives tend to achieve higher levels of work experience accumulation. Relative weight analyses also indicated that cognitive ability and accumulated work experience are the 2 most important predictors for executives’ strategic thinking competency among the other predictors. These findings are discussed in light of their practical implications.     

COGNITIVE AND SOCIOEMOTIONAL FUNCTIONING AT 4½ YEARS IN CHILDREN BORN TO MOTHERS WHO HAVE RECEIVED TREATMENT FOR SUBSTANCE‐ABUSE PROBLEMS WHILE PREGNANT

Cognitive and socioemotional functioning at 4½ years of age were examined in children born to mothers with substance‐abuse problems (n = 22) recruited from residential treatment institutions while pregnant, and then compared to children born to mothers with mental health problems (n = 18) and children from a low‐risk group (n = 26). No significant group differences in cognitive functioning were found, but the children born to mothers with substance‐abuse problems showed more caregiver‐reported socioemotional problems than did the low‐risk children, like the children born to mothers with mental health problems. Birth weight had an effect on internalizing problems at 4½ years and mediated the relation between group and socioemotional problems, although not when controlling for caregiver education, single parenthood, and anxiety and depression. At 4½ years, 7 children born to mothers with substance‐abuse problems were placed in foster care. These children had lower birth weight and higher caregiver‐rated internalizing problems. In addition to emphasizing the importance of the quality of the prenatal environment, this study suggests that families with previous substance abuse are in need of long‐term follow‐up to address socioemotional problems and enhance further positive child cognitive development. The foster‐placed children may be in particular need of long‐term follow‐up.     

TELL ME SOME MORE: EXPLORING HOW VERBAL ABILITY AND ITEM VERIFIABILITY INFLUENCE RESPONSES TO BIODATA QUESTIONS IN A HIGH‐STAKES SELECTION CONTEXT

Although self‐rated or self‐scored selection measures are commonly used in selection contexts, they are potentially susceptible to applicant response distortion or faking. The response elaboration technique (RET), which requires job applicants to provide supporting information to justify their responses, has been identified as a potential way to minimize applicant response distortion. In a large‐scale, high‐stakes selection context (N= 16,304), we investigate the extent to which RET affects responding on a biodata test as well as the underlying reasons for any potential effect. We find that asking job applicants to elaborate their responses leads to overall lower scores on a biodata test. Item verifiability affects the extent to which RET decreases faking, which we suggest is due to increased accountability. In addition, verbal ability was more strongly related to biodata item scores when items require elaboration, although the effect of verbal ability was small. The implications of these findings for reducing faking in personnel selection are delineated.     

FATHER–CHILD INTERACTIONS AT 3 MONTHS AND 24 MONTHS: CONTRIBUTIONS TO CHILDREN'S COGNITIVE DEVELOPMENT AT 24 MONTHS

The quality of father–child interactions has become a focus of increasing research in the field of child development. We examined the potential contribution of father–child interactions at both 3 months and 24 months to children's cognitive development at 24 months. Observational measures of father–child interactions at 3 and 24 months were used to assess the quality of fathers’ parenting (n = 192). At 24 months, the Mental Developmental Index (MDI) of the Bayley Scales of Infant Development, Second Edition (N. Bayley, 1993 ) measured cognitive functioning. The association between interactions and cognitive development was examined using multiple linear regression analyses, adjusting for paternal age, education and depression, infant age, and maternal sensitivity. Children whose fathers displayed more withdrawn and depressive behaviors in father–infant interactions at 3 months scored lower on the MDI at 24 months. At 24 months, children whose fathers were more engaged and sensitive as well as those whose fathers were less controlling in their interactions scored higher on the MDI. These findings were independent of the effects of maternal sensitivity. Results indicate that father–child interactions, even from a very young age (i.e., 3 months) may influence children's cognitive development. They highlight the potential significance of interventions to promote positive parenting by fathers and policies that encourage fathers to spend more time with their young children.

“ÁLL TRÁDES,THEIR GEAR AND TACKLE AND TRIM”: THEOLOGY,COGNITIVE NEUROSCIENCE,AND PSYCHONEUROIMMUNOLOGY IN TRANSVERSAL DIALOGUE

This third of three articles outlining a different approach to science/religion dialogue generally and to engagement between theology and the neurosciences specifically, gives a brief account of the model in practice. It begins by introducing the question to be investigated—whether the experience of relational connection can affect health outcomes by directly moderating immune function. Then, employing the same threefold heuristic of encounter, exchange, and expression used previously, it discusses how the transversal model set out in these articles has been used to investigate this question and to develop a theoretical physiological model for the proposed link between relationality and health.
