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.     

Using a computer simulation of three slot machines to investigate a gambler’s preference among varying densities of near-miss alternatives

The present article describes a software program in Visual Basic .NET designed to simulate three slot machines on a computer screen. This software is described in detail regarding utility, downloading, and usage; and data are presented illustrating the software’s potential for researchers interested in gambling behavior. A simulation of multiple slot machines such as this enables researchers to evaluate players’ preferences across various machines. In the highlighted experiment, 18 recreational slot machine players played the software for extra course credit and a chance at cash prizes. All participants played a version of the simulation in which every 5th response on average was a win, whereas the remaining trials were a loss. However, on those loss trials, a varying distribution of almost wins or near misses (i.e., two winning symbols on the payoff line and the final winning symbol directly above or below the payoff line) were presented in percentages of 15, 30, or 45. While no preferences across the three options could be predicted on the basis of reinforcement history alone, deviations from equal choices across the games were noted and appeared to be the result of the presentations of near-miss losing trials. Implications for a greater understanding of pathological gambling are presented.     

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.     

The alias advantage and perceptions of guilt

The present study is an examination of the perception of guilt based on the number of aliases used by a defendant. Participants in Experiment 1 (N = 275) reviewed materials summarizing an actual crime in which the defendant was identified with no alias information or with 1, 5, or 9 aliases. Participants were asked to decide if the suspect was guilty and if so, what his sentence should be. Results showed that the presence of alias information influenced perceptions of guilt. However, in conditions where the defendant had more aliases, the maximum sentence was imposed less often. Relationship information linking the suspect and the victim in the materials was removed for some of the participants in Experiment 2. Participants (N = 265) were provided with either no alias information or all 9 aliases. An interaction was found in Experiment 2 demonstrating the alias advantage only when the relationship information was present. However, the relationship information had minimal effect on the attributions made toward the victim.     

PC_Eyewitness: Evaluating the New Jersey method

One important variable in eyewitness identification research is lineup administration procedure. Lineups administered sequentially (one at a time) have been shown to reduce the number of false identifications in comparison with those administered simultaneously (all at once). As a result, some policymakers have adopted sequential administration. However, they have made slight changes to the method used in psychology laboratories. Eyewitnesses in the field are allowed to take multiple passes through a lineup, whereas participants in the laboratory are allowed only one pass. PC_Eyewitness (PCE) is a computerized system used to construct and administer simultaneous or sequential lineups in both the laboratory and the field. It is currently being used in laboratories investigating eyewitness identification in the United States, Canada, and abroad. A modified version of PCE is also being developed for a local police department. We developed a new module for PCE, the New Jersey module, to examine the effects of a second pass. We found that the sequential advantage was eliminated when the participants were allowed to view the lineup a second time. The New Jersey module, and steps we are taking to improve on the module, are presented here and are being made available to the research and law enforcement communities.
