On the Cross‐Cultural Replicability of the Resilient,Undercontrolled, and Overcontrolled Personality Types

Personality types reflect typical configurations of personality attributes within individuals. Over the last 20 years, researchers have identified a set of three replicable personality types: resilient (R), undercontrolled (U), and overcontrolled (O) types. In this study, we examined the cross‐cultural replicability of the RUO types in Italy, Poland, Spain, and the United States. Personality types were identified using cluster analyses of Big Five profiles in large samples of college students from Italy (n = 322), the United States (n = 499), Spain (n = 420), and Poland (n = 235). Prior to clustering the profiles, the measurement invariance of the Big Five measure across samples was tested. We found evidence for the RUO types in all four samples. The three‐cluster solution showed a better fit over alternative solutions and had a relatively high degree of cross‐cultural generalizability. The RUO types are evident in samples from four countries with distinct linguistic and cultural traditions. Results were discussed in light of the importance of considering how traits are organized within individuals for advancing contemporary personality psychology.     

Mapping the Personality Psychopathology Five Domains Onto DSM–IV Personality Disorders in Dutch Clinical and Forensic Samples: Implications for DSM–5

The Personality Psychopathology Five (PSY–5) model represents 5 broadband dimensional personality domains that align with the originally proposed DSM–5 personality trait system, which was eventually placed in Section III for further study. The main objective of this study was to examine the associations between the PSY–5 model and personality disorder criteria. More specifically, we aimed to determine if the PSY–5 domain scales converged with the alternative DSM–5 Section III model for personality disorders, with a particular emphasis on the personality trait profiles proposed for each of the specific personality disorder types. Two samples from The Netherlands consisting of clinical patients from a personality disorder treatment program (n = 190) and forensic psychiatric hospital (n = 162) were used. All patients had been administered the MMPI–2 (from which MMPI–2–RF PSY–5 scales were scored) and structured clinical interviews to assess personality disorder criteria. Results based on Poisson or negative binomial regression models showed statistically significant and meaningful associations for the hypothesized PSY–5 domains for each of the 6 personality disorders, with a few minor exceptions that are discussed in detail. Implications for these findings are also discussed.     

Specific Personality Traits and General Personality Dysfunction as Predictors of the Presence and Severity of Personality Disorders in a Clinical Sample

This study examined the associations of specific personality traits and general personality dysfunction in relation to the presence and severity of Diagnostic and Statistical Manual of Mental Disorders (4th ed. [DSM–IV]; American Psychiatric Association, 1994) personality disorders in a Dutch clinical sample. Two widely used measures of specific personality traits were selected, the Revised NEO Personality Inventory as a measure of normal personality traits, and the Dimensional Assessment of Personality Pathology-Basic Questionnaire as a measure of pathological traits. In addition, 2 promising measures of personality dysfunction were selected, the General Assessment of Personality Disorder and the Severity Indices of Personality Problems. Theoretically predicted associations were found between the measures, and all measures predicted the presence and severity of DSM–IV personality disorders. The combination of general personality dysfunction models and personality traits models provided incremental information about the presence and severity of personality disorders, suggesting that an integrative approach of multiple perspectives might serve comprehensive assessment of personality disorders.     

Evidence for habituation of the irrelevant-sound effect on serial recall

Working memory theories make opposing predictions as to whether the disruptive effect of task-irrelevant sound on serial recall should be attenuated after repeated exposure to the auditory distractors. Although evidence of habituation has emerged after a passive listening phase, previous attempts to observe habituation to to-be ignored distractors on a trial-by-trial basis have proven to be fruitless. With the present study, we suggest that habituation to auditory distractors occurs, but has often been overlooked because past attempts to measure habituation in the irrelevant-sound paradigm were not sensitive enough. In a series of four experiments, the disruptive effects of to-be-ignored speech and music relative to a quiet control condition were markedly reduced after eight repetitions, regardless of whether trials were presented in blocks (Exp. 1) or in a random order (Exp. 2). The auditory distractor’s playback direction (forward, backward) had no effect (Exp. 3). The same results were obtained when the auditory distractors were only presented in a retention interval after the presentation of the to-be-remembered items (Exp. 4). This pattern is only consistent with theoretical accounts that allow for attentional processes to interfere with the maintenance of information in working memory.     

Context-specific prospective-memory processing: Evidence for flexible attention allocation adjustments after intention encoding

Prospective memory (PM) is remembering to fulfill intentions in the future. Interference of unfulfilled intentions with ongoing activities reflects the allocation of attention to the PM task. Prior research has shown that, when people know in which specific context PM cues will occur, attention allocation is adaptive, with slower responses in the PM-relevant context. We examined whether people flexibly adjust their attention allocation when the PM–context association is unknown at intention encoding and must be learned on-task. Different stimulus shapes represented contexts in an ongoing task, with PM cues only occurring in trials with one specific shape. Participants informed about the PM-relevant shape responded more slowly on trials with this shape. Participants instructed that only one, unspecified shape was PM-relevant learned the PM–context association and also allocated attention flexibly, depending on context relevance. However, participants with no context-related information at intention encoding failed to learn the PM–context association, resulting in inflexible attention allocation and poorer PM performance. The present study provides evidence that people can flexibly update their attention-allocation policy, and thereby optimize their PM performance after initial intention encoding, but self-guided learning of intention–context associations appears to be limited.     

The General Factor of Personality (GFP) Relates to Other Ratings of Character and Integrity: Two validity studies in personnel selection and training of the Dutch armed forces

In two studies, we tested whether scores on the general factor of personality (GFP) are associated with other ratings of character and integrity. In Study 1, a total of 3,670 applicants for a military job filled out personality surveys and went through a selection interview. GFPs extracted from two different personality surveys showed meaningful relationships with the job suitability judgments based on the interviews. In Study 2, supervisors rated the integrity of participants (N = 167) who followed a 4‐month military training at the Royal Dutch Military Police. GFPs extracted from three different surveys were correlated with integrity. The findings imply that the GFP is associated with behavioral outcomes, and that the GFP is potentially relevant for personnel selection and appraisal.     

Electrophysiological evidence for greater attention to threat when cognitive control resources are depleted

In this study, we investigated the time course of attentional bias for threat-related (angry) facial expressions under conditions of high versus low cognitive (working memory) load. Event-related potential (ERP) and reaction time (RT) data were recorded while participants viewed pairs of faces (angry paired with neutral face) displayed for 500 ms and followed by a probe. Participants were required to respond to the probe while performing a concurrent task of holding in working memory a sequence of digits that were either in the same order (low memory load) or in a random mixed order (high memory load). The ERP results revealed that higher working memory load resulted in enhanced lateralized neural responses to threatening relative to neutral faces, consistent with greater initial orienting of attention to threatening faces (early N2pc: 180–252 ms) and enhanced maintenance of processing representations of threat (late N2pc, 252–320 ms; SPCN, 320–500 ms). The ERP indices showed significant positive relationships with each other, and also with the behavioral index of attentional bias to threat (reflected by faster RTs to probes replacing angry than neutral faces at 500 ms), although the latter index was not significantly influenced by memory load. Overall, the findings indicate that depletion of cognitive control resources, using a working memory manipulation, increases the capacity of task-irrelevant threat cues to capture and hold attention.     

Tracking of nociceptive thresholds using adaptive psychophysical methods

Psychophysical thresholds reflect the state of the underlying nociceptive mechanisms. For example, noxious events can activate endogenous analgesic mechanisms that increase the nociceptive threshold. Therefore, tracking thresholds over time facilitates the investigation of the dynamics of these underlying mechanisms. Threshold tracking techniques should use efficient methods for stimulus selection and threshold estimation. This study compares, in simulation and in human psychophysical experiments, the performance of different combinations of adaptive stimulus selection procedures and threshold estimation methods. Monte Carlo simulations were first performed to compare the bias and precision of threshold estimates produced by three different stimulus selection procedures (simple staircase, random staircase, and minimum entropy procedure) and two estimation methods (logistic regression and Bayesian estimation). Logistic regression and Bayesian estimations resulted in similar precision only when the prior probability distributions (PDs) were chosen appropriately. The minimum entropy and simple staircase procedures achieved the highest precision, while the random staircase procedure was the least sensitive to different procedure-specific settings. Next, the simple staircase and random staircase procedures, in combination with logistic regression, were compared in a human subject study (n = 30). Electrocutaneous stimulation was used to track the nociceptive perception threshold before, during, and after a cold pressor task, which served as the conditioning stimulus. With both procedures, habituation was detected, as well as changes induced by the conditioning stimulus. However, the random staircase procedure achieved a higher precision. We recommend using the random staircase over the simple staircase procedure, in combination with logistic regression, for nonstationary threshold tracking experiments.
