INCREMENTAL VALIDITY OF PERCEPTUAL SPEED AND ACCURACY OVER GENERAL MENTAL ABILITY

This study extends previous research by examining the incremental validity of a specific aptitude, perceptual speed and accuracy (PS), when it is operationalized as both the number correct (NC) and the number wrong (NW). We test the hypotheses that the NC on the PS test predicts the criterion of task performance and the NW predicts (negatively) rules compliance (RC). Based on the responses of 133 warehouse workers, hierarchical regression analyses supported both hypotheses. After controlling for respondents' demographic characteristics (race, gender, and age) and general mental ability (GMA), the NC on the PS test accounted for incremental validity in prediction of task performance (Δ R = .06, 15% increase), and the NW on the PS test accounted for substantial incremental validity in prediction of (lack of) RC (Δ R = .16, 73% increase). In addition, after controlling for demographic characteristics and both GMA and the specific ability, Conscientiousness accounted for unique validity in prediction of both task performance (Δ R = .07, 15% increase) and RC (Δ R = .06, 16% increase). Practical and theoretical implications for selection practices and models of job performance are discussed.     

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.     

Information processing bias against emotional facial expressions in social anxiety

The present study examined whether information processing bias against emotional facial expressions is present among individuals with social anxiety. College students with high (high social anxiety group; n  = 26) and low social anxiety (low social anxiety group; n  = 26) performed three different types of working memory tasks: (a) ordering positive and negative facial expressions according to the intensity of emotion; (b) ordering pictures of faces according to age; and (c) ordering geometric shapes according to size. The high social anxiety group performed significantly more poorly than the low social anxiety group on the facial expression task, but not on the other two tasks with the nonemotional stimuli. These results suggest that high social anxiety interferes with processing of emotionally charged facial expressions.     

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.     

INCREASING THE ACCURACY OF CORRECTIONS FOR RANGE RESTRICTION: IMPLICATIONS FOR SELECTION PROCEDURE VALIDITIES AND OTHER RESEARCH RESULTS

The common practice in meta-analyses and in individual studies of correcting for direct range restriction even though range restriction is actually indirect has long been known to lead to undercorrection, but this error has been assumed to be small. Using validity generalization data sets for 4 jobs, this study calibrated this error by comparing meta-analysis results based on corrections for direct range restriction with the more accurate results from a recently developed method of correcting for indirect range restriction. It was found that, on average, correction for direct range restriction resulted in substantial underestimation of operational validities for both job performance measures (21%) and training performance measures (28%). In addition, 90% credibility values were on average underestimated by 38%–40%. In addition to the implications for personnel selection, these findings suggest that similar underestimation of important relationships has occurred in other areas of research, with potential implications for theory development.     

TOWARD BETTER META‐ANALYTIC MATRICES: HOW INPUT VALUES CAN AFFECT RESEARCH CONCLUSIONS IN HUMAN RESOURCE MANAGEMENT SIMULATIONS

Simulations and analyses based on meta‐analytic matrices are fairly common in human resource management and organizational behavior research, particularly in staffing research. Unfortunately, the meta‐analytic values estimates for validity and group differences (i.e., ρ and δ, respectively) used in such matrices often vary in the extent to which they are affected by artifacts and how accurately the values capture the underlying constructs and the appropriate population. We investigate how such concerns might influence conclusions concerning key issues such as prediction of job performance and adverse impact of selection procedures, as well as noting wider applications of these issues. We also start the process of building a better matrix upon which to base many such simulations and analyses in staffing research. Finally, we offer guidelines to help researchers/practitioners better model human resources processes, and we suggest ways that researchers in a variety of areas can better assemble meta‐analytic matrices.
