Structural Analysis of the Trauma Symptom Inventory–2

The Trauma Symptom Inventory (TSI; Briere, 1995), a measure of the psychological effects of trauma and other adverse events, was recently expanded and updated (TSI–2; Briere, 2011). This study evaluated 4 competing models of TSI–2 dimensionality and determined the predictive validity of the best fitting solution. Data were collected from 679 adults in the general population. Confirmatory factor analysis indicated that a 4-factor solution best fit the data. All 4 factors of the final model were significant predictors of exposure to trauma or some other very upsetting event, especially posttraumatic stress. Additional research is indicated to further probe the characteristics of the TSI–2, including its dimensionality in other groups.     

Age Differences in the Variance of Personality Characteristics

In contrast to mean‐level comparisons, age group differences in personality trait variance have received only passing research interest. This may seem surprising because individual differences in personality characteristics are exactly what most of personality psychology is about. Because different proposed mechanisms of personality development may entail either increases or decreases in variance over time, the current study is exploratory in nature. Age differences in variance were tested by comparing the standard deviations of the five‐factor model domain and facet scales across two age groups (20 to 30 years old versus 50 to 60 years old). Samples from three cultures (Estonia, the Czech Republic and Russia) were employed, and two methods (self‐reports and informant‐reports) were used. The results showed modest convergence across samples and methods. Age group differences were significant for 11 of 150 facet‐level comparisons but never consistently for the same facets. No significant age group differences were observed for the five‐factor model domain variance. Therefore, there is little evidence for individual differences in personality characteristics being systematically smaller or larger in older as opposed to younger people. We discuss the implications of these findings for understanding personality development. Copyright © 2015 European Association of Personality Psychology     

A Danish version of the Sensation Seeking Scale and its relation to a broad spectrum of behavioral and psychological characteristics

The primary purpose of the present study was to evaluate the internal consistency and construct validity of the Danish translation of Zuckerman's Sensation Seeking Scale (SSS). The secondary aim was to extend the range of psychological variables and behaviors that have been related to sensation seeking. The sample consisted of 691 subjects (363 males and 328 females) with a mean age of 31.7 years. The internal consistency of the scales was evaluated by coefficient alpha and intercorrelations among the five scales derived from the SSS were computed. Information on other variables was collected through standardized tests as well as questionnaires and interviews developed especially for this study. The results showed that the Danish SSS is a psychometrically sound instrument and revealed the relationship between sensation seeking and a broad spectrum of psychological traits and behaviors: socioeconomic status, academic achievement, intelligence, personality, smoking, alcohol and drug use, sexuality, driving and public transportation violations, and leisure time activities. Thus, this study confirmed and expanded the findings of many previous studies, while the results supported the validity of the Danish SSS and corroborated the usefulness of the concept of sensation seeking.     

What's different in second-language processing? Evidence from event-related brain potentials

German sentences which were either correct, contained a selectional restriction violation, or a word category violation were presented auditorily to 16 native speakers of German (L1 group) and to 16 native speakers of Russian, who had learned German after the age of 10 (L2 group). Semantic violations elicited an N400 effect for both groups, but with a reduced amplitude and a longer peak latency in the L2 group. Compared to correct sentences, sentences with a phrase structure violation elicited an early anterior negativity followed by a broad centro-parietal positivity in native speakers. By contrast, there was no differential modulation of the early anterior negativity in the L2 group. A late positivity was also elicited in the second language learners, but it was slightly delayed compared to that shown by native speakers. This pattern is discussed in terms of different degrees of automaticity with respect to the subprocesses involved in sentence comprehension.     

Effects of varying numbers of Likert scale points on factor structure of the Rosenberg Self‐Esteem Scale

Likert‐type rating scales are among the most widely used tools in psychological research. Different numbers of response categories would likely affect response style, data distribution, reliability, and construct validity. There is a lack of research in factor structure invariance under Likert scales with different numbers of categories. The purpose of this study is to examine the effects of varying numbers of Likert points (4–11) on scale properties such as factor structure, external validity, and latent means based on the Rosenberg Self‐Esteem Scale (M. Rosenberg, 1989 ). The sample consists of 1,807 students from secondary schools in Macau. Confirmatory factor analysis shows that the correlated two‐factor model is the most appropriate one; longitudinal invariance analysis reveals that measurement invariance across Likert scales was satisfied at the scalar level. In addition, latent mean scores on the two factors as well as observed means on the subscales are comparable across Likert scales. Moreover, the measurement model across Likert scales exhibit similar external validity. Although psychometric properties are mostly similar among a different number of points, the 4‐point Likert scale is not recommended for its higher skewness and lower loadings; the 11‐point Likert scale from 0 to 10 is slightly preferred for its higher loadings and composite reliability.     

Ethnic Inequality and National Pride

This article examines patterns in individual attachments towards the nation‐state in multiethnic countries. Specifically, we examine the effect of between‐ethnic‐group political and economic inequality on these attachments. Pairing attitudinal data from the sixth and most recent wave of the World Values Survey, administered between 2010 and 2012, with ethnicity measures from the Ethnic Power Relations dataset, we show that between‐ethnic‐group political inequality significantly weakens national pride and identity, but between‐ethnic‐group economic inequality does not have a similar effect. Our findings provide robust support for the view that ethnic‐group separatism in divided societies is motivated, not by the quest for economic power, but by considerations of lost status and dignity that can only be recovered through ownership in state institutions. Hence, the binding constraint on national integration in these settings is political, not economic, inequality.

In DeFENCE of the In‐Group Historical Narrative in an Intractable Intergroup Conflict: An Individual‐Difference Perspective

Groups, particularly when immersed in an intractable intergroup conflict, place considerable value on protecting and defending their historical group narrative. However, some group members are more narrative‐protective than others. In Study 1, we introduce a new individual‐difference measure of motivation to achieve a Firmly Entrenched Narrative ClosurE (FENCE) and test it on several Israeli samples (N = 1132). In Study 2 (N = 120), we show that in‐group glorification, right‐wing political orientation, and right‐wing‐authoritarianism, but not attachment to the In‐group, nonspecific need for cognitive closure, or need for cognition, predict FENCE motivation and Behavioral Lack of Openness to Counternarratives (BLOC). In Studies 3 and 4, we show using international (N = 24) and Israeli (N = 78) samples that a belief in the zero‐sum nature of the conflict is related to FENCE and BLOC. In Study 5, we demonstrate that FENCE affects quality of recall of conflict information. The potential merit of FENCE in accounting for the variability among group members in protecting the group narrative is discussed.     

The relationship between working memory capacity and cortical activity during performance of a novel motor task

ObjectivesThis study assessed whether individual differences in working memory capacity influenced verbal-analytical processes when performing a novel motor skill.DesignParticipants performed a tennis-hitting task in two conditions: no pressure and high-pressure.MethodsEighteen young adults participated in the study. EEG coherence between the T3-F3 and T4-F4 regions in the Beta1 and Alpha2 frequencies was recorded during performance in each condition. Verbal and visuo-spatial working memory capacity were assessed using the Automated Working Memory Assessment.ResultsNo differences were found between the two conditions for hitting performance and EEG activity. However, across both conditions, verbal and visuo-spatial working memory were significant predictors of EEG coherence between the T3-F3 and T4-F4 regions in the Beta1 and Alpha2 frequencies. Larger verbal working memory capacity was associated with greater coherence while the opposite trend was observed for visuo-spatial working memory capacity.ConclusionsThese results indicate that larger verbal working memory capacity is associated with a greater tendency to use explicit processes during motor performance, whereas larger visuo-spatial working memory capacity is associated more with implicit processes. The findings are discussed with relevance to the theory of implicit motor learning.     

Maximizing Scales Do Not Reliably Predict Maximizing Behavior in Decisions from Experience

In this paper, we explore the relationships between psychometric and behavioral measures of maximization in decisions from experience (DfE). In two experiments, we measured choice behavior in two experimental paradigms of DfE and self‐reported maximizing tendencies using three prominent scales of maximization. In the repeated consequentialist choice paradigm, participants made repeated choices between two unlabeled options and received consequential feedback on each trial. In the sampling paradigm, participants freely sampled from two options and received feedback on their sampling before making a single consequential choice. Individuals exhibited different degrees of maximizing behavior in both paradigms and across different payoff distributions, but none of the maximizing scales predicted this behavior. These results indicate that maximization scales address constructs that are different from the maximization behavior observed in DfE, and that these measures will need to be improved to reflect behavioral aspects of choice and search from experience.
