Are DSM-IV-TR Borderline Personality Disorder, ICD-10 Emotionally Unstable Personality Disorder, and CCMD-III Impulsive Personality Disorder Analogous Diagnostic Categories Across Psychiatric Nomenclatures?

This study examined the validity of the borderline construct which encompasses diagnostic criteria from the DSM-IV-TR Borderline Personality Disorder (BPD), ICD-10 Emotionally Unstable Personality Disorder (EUPD), and CCMD-III Impulsive Personality Disorder (IPD) in a sample of 1,419 Chinese psychiatric patients. Participants completed the Chinese Personality Disorder Inventory and the Chinese Personality Assessment Inventory-2 assessing various disordered personality features. Adequate internal consistency was found for the borderline construct (α = .83). Exploratory factor analysis revealed two components: (1) affective and cognitive disturbances, and (2) impulse dysregulation, which were replicated by confirmatory factor analysis. Item analysis indicated that the various borderline criteria displayed similar levels of diagnostic efficiency, which does not support the elimination of fear of abandonment and transient psychotic features from the EUPD and IPD criteria set. Findings of this study suggest that BPD, EUPD, and IPD may represent analogous diagnostic categories across classification systems.     

Parental, peer, and teacher influences on the social behavior of Hong Kong Chinese adolescents

Intensive interviews and self-report questionnaires were used to investigate parental, peer, and teacher influences on the prosocial and antisocial behaviors of Hong Kong Chinese adolescents. Students came from 5 academically different high schools. Results indicated that perceived parental influence was positively associated with frequency of prosocial behavior and negatively associated with frequency of delinquent behavior. Students with good relationships with their parents and peers showed lower frequencies of antisocial behaviors than did students with bad relationships. Adolescents in different identity statuses (achievement, moratorium, foreclosure, diffusion; E. H. Erikson, 1968) showed different patterns of prosocial and antisocial behaviors. For example, adolescents in the identity achievement group exhibited high frequencies of prosocial behaviors and low frequencies of antisocial behaviors, but those in the identity moratorium group exhibited quite high frequencies of both prosocial and antisocial behaviors.     

The differential effects of thalamus and basal ganglia on facial emotion recognition

This study examined if subcortical stroke was associated with impaired facial emotion recognition. Furthermore, the lateralization of the impairment and the differential profiles of facial emotion recognition deficits with localized thalamic or basal ganglia damage were also studied. Thirty-eight patients with subcortical strokes and 19 matched normal controls volunteered to participate. The participants were individually presented with morphed photographs of facial emotion expressions over multiple trials. They were requested to classify each of these morphed photographs according to Ekman's six basic emotion categories. The findings indicated that the clinical participants had impaired facial emotion recognition, though no clear lateralization pattern of impairment was observed. The patients with localized thalamic damage performed significantly worse in recognizing sadness than the controls. Longitudinal studies on patients with subcortical brain damage should be conducted to examine how cognitive reorganization post-stroke would affect emotion recognition.     

The ties that keep us bound: Top-down influences on the persistence of shape-from-motion

The phenomenon of perceptual persistence after the motion stops in shape-from-motion displays (SFM) was used to study the influence of prior knowledge on the maintenance of a percept in awareness. In SFM displays an object composed of discontinuous line segments are embedded in a background of randomly oriented lines. The object only becomes perceptible when the line segments that compose the object and the lines that compose the background move in counterphase. Critically, once the movement of the line segments stops, the percept of the object persists for a short period of time. In the present study, perceptual persistence for digits exceeded that reported for nonsense shapes composed of the same line segments. This result is taken as evidence that the processes involved in the persistence of SFM, and therefore sustained perception, are sensitive to top-down influences.     

Modeling heterogeneity in social interaction processes using multilevel survival analysis

More than 15 years ago, survival or hazard regression analyses were introduced to psychology (W. Gardner & W. A. Griffin, 1989; W. A. Griffin & W. Gardner, 1989) as powerful methodological tools for studying real time social interaction processes among dyads. Almost no additional published applications have appeared, although such data are commonly collected and the applicable questions are central to many important theoretical perspectives. To revisit the basic methods, the authors use an example from emotion regulation theory in which the level of child antisocial behavior is hypothesized to be positively associated with the hazard rate of angry emotions and negatively associated with sad, fearful emotions in the face of parental negative behavior (scolding). The authors discuss the limitations of traditional approaches to the analysis of social interaction and demonstrate improvements in the ability to model individual differences now available in existing software.     

Task preparation and stimulus-evoked competition

The authors investigated how task competition evoked by a stimulus that affords both a currently relevant and a temporarily irrelevant task is affected by invalid preparation, i.e., preparation for the irrelevant task. Although invalid preparation was associated with a general performance cost, effects of stimulus-cued task competition were not enhanced on invalidly prepared trials. This result suggests that either preparation activates representations different from the ones by which stimulus cuing is mediated or that stimulus processing is postponed until invalid preparation has been corrected. In addition, invalid preparation resulted in impaired performance of the respective task when it became relevant on a subsequent trial. This result is consistent with the idea that competition due to invalid preparation is countered by task-specific inhibition.     

The roles of inducer size and distance in the Ebbinghaus illusion (Titchener circles)

Although the Ebbinghaus illusion is commonly used as an example of a simple size-contrast effect, previous studies have emphasised its complexity by identifying many factors that potentially influence the magnitude of the illusion. Here, in a series of three experiments, we attempt to simplify this complexity. In each trial, subjects saw a display comprising, on one side, a target stimulus surrounded by inducers and, on the other, an isolated probe stimulus. Their task was to indicate whether the probe appeared larger or smaller than the target. Probe size was adjusted with a one-up, one-down staircase procedure to find the point of subjective equality between probe and target. From these experiments, we argue that the apparent effects of inducer size are often confounded by the relative completeness of the inducing surround and that factors such as the similarity of the inducers and target are secondary. We suggest a simple model that can explain most of the data in terms of just two primary and independent factors: the relative size of the inducers and target, and the distance between the inducers and the target. The balance between these two factors determines whether the size of the target is underestimated or overestimated.     

Cognitive processes underlying coping flexibility: differentiation and integration

This study investigates how individuals formulate flexible coping strategies across situations by proposing differentiation and integration as two stress-appraisal processes. Results showed that participants who coped more flexibly adopted the dimensions of controllability and impact in differentiating among different stressful situations. They also deployed an integrated strategy: the deployment of more monitoring in situations perceived as controllable but less of this strategy in situations perceived as uncontrollable. Participants who coped less flexibly did not adopt any given dimensions and tended to use more monitoring regardless of situational characteristics. These results suggest that individuals with different extents of coping flexibility differ in the cognitive processes. Individuals who cope more flexibly display a greater extent of differentiation and integration than do those who cope less flexibly. These findings are translated into strategies for stress management workshops.     

Meta-analytic structural equation modeling: a two-stage approach

To synthesize studies that use structural equation modeling (SEM), researchers usually use Pearson correlations (univariate r), Fisher z scores (univariate z), or generalized least squares (GLS) to combine the correlation matrices. The pooled correlation matrix is then analyzed by the use of SEM. Questionable inferences may occur for these ad hoc procedures. A 2-stage structural equation modeling (TSSEM) method is proposed to incorporate meta-analytic techniques and SEM into a unified framework. Simulation results reveal that the univariate-r, univariate-z, and TSSEM methods perform well in testing the homogeneity of correlation matrices and estimating the pooled correlation matrix. When fitting SEM, only TSSEM works well. The GLS method performed poorly in small to medium samples.
