Development of a Response Inconsistency Scale for the Personality Inventory for DSM–5

The advent of a dimensional model of personality disorder included in DSM–5 has necessitated the development of a new measurement scheme, specifically a self-report questionnaire termed the Personality Inventory for DSM–5 (PID–5; Krueger, Derringer, Markon, Watson, &; Skodol, 2012 Krueger, R. F., Derringer, J., Markon, K. E., Watson, D., &; Skodol, A. E. (2012). Initial construction of a maladaptive personality trait model and inventory for DSM–5. Psychological Medicine, 42, 1879–1890. doi:10.1017/S0033291711002674[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]). However, there are many threats to the validity of a self-report measure, including response inconsistency. This study outlines the development of an inconsistency scale for the PID–5. Across both college student and clinical samples, the inconsistency scale was able to reliably differentiate real from random responding. Random responses led to increased scores on the PID–5 facets, indicating the importance of detecting inconsistent responding prior to test interpretation. Thus, this inconsistency scale could be of use to researchers and clinicians in detecting inconsistent responses to this new personality disorder measure.     

Cross-Community Contact, Perceived Status Differences, and Intergroup Attitudes in Northern Ireland: The Mediating Roles of Individual-level versus Group-level Threats and the Moderating Role of Social Identification

We tested a model which examined the relationship between contact quantity and quality, relative ingroup status, and intergroup attitudes in Northern Ireland. Intergroup anxiety was considered an individual-level mediator and realistic and symbolic threat as group-level mediators in the model. We examined the idea that the strength of ingroup identification moderates the predictive power of individual- versus group-level variables. Both contact and relative ingroup status predicted anxiety and perceived threats to the ingroup, which were significant mediators in the model. Our results also suggest that while anxiety predicts attitudes for low but not high identifiers, symbolic threats to the ingroup are more important for high than for low identifiers. There was also some evidence indicating that status perceptions moderate contact effects. We discuss these results in terms of their implications for intergroup relations in Northern Ireland.     

The activation of phonological representations by bilinguals while reading silently: evidence from interlingual homophones

These experiments investigated whether bilinguals activate phonological representations from both of their languages when reading silently in one. The critical stimuli were interlingual homophones (e.g., sank in English and cinq in French). French-English and English-French bilinguals completed an English lexical decision task. Decisions made by French-English bilinguals were significantly faster and more accurate for interlingual homophones than for matched English control words. In subsequent experiments, the homophone facilitation effect in the latency data disappeared when distractors were changed to pseudohomophones, when cognates and interlingual homographs were added to the experiment, and when the proportion of critical stimuli was decreased. However, the homophone effect in the error data remained. In contrast, English-French bilinguals revealed little evidence of an interlingual homophone effect. Several attempts were made to increase the saliency of the nontarget language, however these manipulations produced only a small effect in the error data. These results indicate that the activation of phonological representations can appear to be both language-specific and nonspecific depending on the proficiency of the bilinguals and whether they are reading in their weaker or stronger language.     

The effect of Parkinson's disease on time estimation as a function of stimulus duration range and modality

The present research sought to investigate the role of the basal ganglia in timing of sub- and supra-second intervals via an examination of the ability of people with Parkinson's disease (PD) to make temporal judgments in two ranges, 100-500 ms, and 1-5 s. Eighteen non-demented medicated patients with PD were compared with 14 matched controls on a duration-bisection task in which participants were required to discriminate auditory and visual signal durations within each time range. Results showed that patients with PD exhibited more variable duration judgments across both signal modality and duration range than controls, although closer analyses confirmed a timing deficit in the longer duration range only. The findings presented here suggest the bisection procedure may be a useful tool in identifying timing impairments in PD and, more generally, reaffirm the hypothesised role of the basal ganglia in temporal perception at the level of the attentionally mediated internal clock as well as memory retrieval and/or decision-making processes.     

Memories of social interactions: age differences in emotional intensity

The current study examined age differences in the intensity of emotions experienced during social interactions. Because emotions are felt most intensely in situations central to motivational goals, age differences in emotional intensity may exist in social situations that meet the goals for one age group more than the other. Guided by theories of emotional intensity and socioemotional selectivity, it was hypothesized that social partner type would elicit different affective responses by age. Younger (n = 71) and older (n = 71) adults recalled experiences of positive and negative emotions with new friends, established friends, and family members from the prior week. Compared with younger adults, older adults reported lower intensity positive emotions with new friends, similarly intense positive emotions with established friends, and higher intensity positive emotions with family members. Older adults reported lower intensity negative emotions for all social partners than did younger adults, but this difference was most pronounced for interactions with new friends.     

The confirmability and disconfirmability of trait concepts revisited: does content matter?

M. Rothbart and B. Park (1986) demonstrated that, consistent with the common negativity bias, positive traits are difficult to confirm and easy to disconfirm, whereas the opposite is true for negative traits. This article extends their analysis by showing that trait (dis-)confirmability is moderated by trait content (warmth vs. competence). Study 1 identifies a trait sample representative of warmth and competence. Study 2 shows a strong negativity effect for warmth and a reduced (or absent) negativity effect for competence. Study 3 examines trait properties related to the behavioral range of the trait possessor and to the motivational goals of the perceiver as predictors of trait (dis-)confirmability. The theoretical and practical implications of the authors' findings are discussed, and avenues for future research are suggested.     

Use of a high‐probability instructional sequence to increase compliance to feeding demands in the absence of escape extinction

We evaluated the effects of a high‐probability (high‐p) instructional sequence on the feeding‐related compliance (food acceptance) of a young boy diagnosed with a feeding disorder. The high‐p sequence consisted of three presentations of an empty spoon; the low‐probability (low‐p) instruction was the presentation of a spoon with food. Results showed that acceptance of food increased in the presence and not the absence of the high‐p sequence. Data are discussed in terms of the role of high‐p instructional sequences in the treatment of feeding problems. Copyright © 2007 John Wiley & Sons, Ltd.     

The relationship between the youth psychopathic traits inventory and psychopathology in a U.S. community sample of male youth

The Youth Psychopathic Traits Inventory (YPI) is a self-report measure of juvenile psychopathic traits. Validity data for this measure are limited, especially for nonreferred samples. This report investigated the concurrent validity of the YPI by assessing 171 nonreferred male youth (M age = 12.96 years) with a battery of self-, parent-, and peer-report measures including the Child Behavior Checklist (CBCL), the Reactive-Proactive Aggression Questionnaire (RPQ), the Antisocial Process Screening Device (APSD), and a peer-sociometric measure of aggression. Results confirmed the expected correlations between the YPI and measures of proactive aggression, other externalizing and internalizing behavior, and parent-report psychopathic-like traits. In addition, cluster analyses of YPI scores revealed 2 groups of youth (low vs. high) who scored differently on measures of externalizing behavior. This study supports the utility of the YPI as a research tool for assessing juvenile psychopathic traits.
