The effective time course of preparation

In reaction time (RT) research on nonspecific preparation, the preparation period is often identified with the foreperiod (FP), the interval between the offset of a neutral warning stimulus (S1) and the onset of the reaction stimulus (S2). However, the “effective preparation period” may be longer than FP: nonspecific preparation may start prior to FP (e.g., at the onset of S1) and/or continue after it (i.e., in parallel with the reaction process). In four experiments, we factorially varied FP and an additional factor (S1-duration; S2-luminance; stimulus–response compatibility) that probed the effective preparation period outside the bounds of FP. By examining how equivalent RT–FP functions obtain at the different levels of the additional factor, we showed that nonspecific preparation (1) starts at the onset of S1 for brief FPs but at its offset for longer FPs and (2) continues in parallel with S2-encoding but stops prior to response selection.     

Taxometric analyses of borderline personality features in a large-scale male and female offender sample

Few studies to date have examined the extent to which borderline personality features are best construed as representing an underlying dimension or a discrete class or taxon. The authors conducted taxometric analyses using a large-scale sample of male (n=787) and female (n=368) prison inmates who had completed the Personality Assessment Inventory (L. C. Morey, 2007). Analyses based on the 4 subscales of the Borderline Features Scale offered compelling support for a dimensional structure in both the full sample and the female subsample--even after controlling for the potentially confounding effects of negative response distortion. Theoretical and pragmatic implications of these findings are reviewed.     

Attention to internal face features in unfamiliar face matching

Accurate matching of unfamiliar faces is vital in security and forensic applications, yet previous research has suggested that humans often perform poorly when matching unfamiliar faces. Hairstyle and facial hair can strongly influence unfamiliar face matching but are potentially unreliable cues. This study investigated whether increased attention to the more stable internal face features of eyes, nose, and mouth was associated with more accurate face‐matching performance. Forty‐three first‐year psychology students decided whether two simultaneously presented faces were of the same person or not. The faces were displayed for either 2 or 6 seconds, and had either similar or dissimilar hairstyles. The level of attention to internal features was measured by the proportion of fixation time spent on the internal face features and the sensitivity of discrimination to changes in external feature similarity. Increased attention to internal features was associated with increased discrimination in the 2‐second display‐time condition, but no significant relationship was found in the 6‐second condition. Individual differences in eye‐movements were highly stable across the experimental conditions.     

Detecting over- and underreporting of psychopathology with the Spanish-language Personality Assessment Inventory: findings from a simulation study with bilingual speakers

Existing research on the Spanish-language translation of the Personality Assessment Inventory (PAI; L. C. Morey, 1991) suggests that the validity scales from the English- and Spanish-language versions may not be equivalent measures. In the current study, 72 bilingual participants completed both the English- and Spanish-language versions of the PAI under the instructions to respond honestly, to overreport psychopathology for an insanity case, or to underreport psychopathology for an employment evaluation. Overall, the English- and Spanish-language validity scales performed similarly, and scores from the Negative Impression Management and the Positive Impression Management scales demonstrated the highest levels of equivalence and accuracy for the identification of simulators across language versions.     

Forced Termination of American Clergy: Its Effects and Connection to Negative Well-Being

Forced termination of clergy involves constant negativity found in personal attacks and criticism from a small congregational faction. The minister feels psychologically pressured to step down from the ministry position and this process is often demeaning to the emotional and physical well-being of the minister. The prevalence of forced termination among clergy has ranged from 25% among many denominations to 41% among Assemblies of God ministers. Forced termination and its effects are serious problems that have yet to be adequately addressed by scholars in social science research. The lack of scholarly research in this area called for a large national study from a reputable research institution. This online study shows that 28% of ministers among 39 denominations experienced a forced termination. Forced termination was associated with high levels of depression, stress, and physical health problems. Forced termination was also associated with low levels of self-efficacy, and self-esteem.     

The effects of unavoidable shocks on a multiple schedule having an avoidance component

Two dogs were maintained on a multiple schedule having both a food reinforced and an avoidance component (Mult VI 1′ S^Δ Avoid_{SS20 RS20} S^Δ). The effects of superimposing an Estes-Skinner procedure for delivering unavoidable shocks on all components of the multiple schedule were observed. The buzzer-shock pairing of the Estes-Skinner procedure produced an increased rate of responding on the avoidance component of the schedule and also on the S^Δ components. No persistent change in rate was observed on the food component during the pre-shock stimulus. Control performances on all components could be regained by either extinguishing or eliminating the buzzer-shock pairing. Extinction of the avoidance responding had little effect on the increased rates of responding produced by the Estes-Skinner procedure on the S^Δ and avoidance extinction components and did not lead to a conditioned suppression of the food reinforced responding. Rate of responding during the pre-shock stimulus was observed to be relatively independent of changes in the maintaining schedules. Responding during the pre-shock stimulus could be conditioned and maintained after an extensive history of avoidance extinction.     

Screening for malingering in a criminal-forensic sample with the personality assessment inventory

In this study, the authors examined how overreporting of psychopathology indices on the Personality Assessment Inventory (PAI; L. C. Morey, 1991) performed as screening measures for malingering in a sample of 166 defendants undergoing pretrial court-ordered evaluations in the federal criminal justice system. Using results from the Structured Interview of Reported Symptoms (SIRS; R. Rogers, R. M. Bagby, & S. E. Dickens, 1992) as the criterion measure of malingering, the authors found that the Negative Impression scale (NIM) was the most effective PAI screening measure (cut score > or = 81 T). NIM performed as well as an established comparison measure from the Minnesota Multiphasic Personality Inventory--2 (J. N. Butcher, W. G. Dahlstrom, J. R. Graham, A. Tellegen, & B. Kaemmer, 1989; Infrequency [F] cut score > or = 95 T), supporting the use of either of these indices as reasonable screening measures to identify potential malingerers for subsequent evaluation.
