Temperament and Social-Emotional Difficulties: The Dark Side of Learning Disabilities

The authors compared the relations between general psychological difficulties and dimensions of temperament in children with and without learning disability (LD). The main aim was to analyze whether and to what extent children's temperament dimensions contribute to their general psychological difficulties when LD diagnosis, age, and gender are taken into account. Participants were 52 elementary school children 7–11 years old (M age = 8.61 years, SD = 1.21 years). Twenty-six of them had been diagnosed with LD. Six teachers rated their pupils with and without LD in relation to their general psychological difficulties (Strengths and Difficulties Questionnaire) and temperament dimensions (Italian Questionnaires of Temperament). In children with LD, the main dimensions of temperament with the power to predict general psychological difficulties (i.e., emotionality and social orientation) concern these students' relationships with others (teachers and peers). The findings of the current study draw educators' and practitioners' attention to the fact that children's temperamental characteristics may affect how they experience their LD, with significant implications for their later social adjustment.     

Gender Bias in the Measurement of Workaholism

Past research suggests gender differences in workaholism might be due to differences in how men and women respond to the item content in workaholism measures. Using item response theory differential item functioning, we show women are less likely to report some workaholism items, leading to contamination. Specifically, women are less likely to report spending more time at work than other activities, and staying at work longer than others. We speculate that societal norms and practical restrictions on women's time results in lower endorsement rates for these items compared to men, and thus underestimates their workaholism. Results contradict past findings that men and women are similar in regard to workaholism and suggest women are in fact higher in workaholism than men. Limitations and future directions are discussed.

Death anxiety and sexual risk-taking: different manifestations of the process of defense

College students(n = 162) completed measures of death anxiety and sexual risk-taking, with a thought listing procedure in-between. Those who completed the death anxiety measure first (Death Salient condition) reportedgreater willingness to engage in high-risk sexual behavior than the Non-Death Salient group. This result was consistent with the hypothesis that evoking death anxiety would produce denial-based defensive activity. Also, Death Salient participants reporting more death thoughts were lower on risk-taking, as predicted. Interestingly, Death Salient participants reporting stressful thoughts about issues unrelated to personal mortality (displacement) were also less willing to engage in high-risk sexual behavior. The results are discussed in relation to a new, avowal-based model of the process of psychological defense.     

Exploring the Public Understanding of Basic Genetic Concepts

It is predicted that the rapid acquisition of new genetic knowledge and related applications during the next decade will have significant implications for virtually all members of society. Currently, most people get exposed to information about genes and genetics only through stories publicized in the media. We sought to understand how individuals in the general population used and understood the concepts of “genetics” and “genes.” During in-depth one-on-one telephone interviews with adults in the United States, we asked questions exploring their basic understanding of these terms, as well as their belief as to the location of genes in the human body. A wide range of responses was received. Despite conversational familiarity with genetic terminology, many noted frustration or were hesitant when trying to answer these questions. In addition, some responses reflected a lack of understanding about basic genetic science that may have significant implications for broader public education measures in genetic literacy, genetic counseling, public health practices, and even routine health care.     

A Structural Equation Model for the School Reinforcement Survey Schedule: Italian and American Early Adolescents

The School Reinforcement Survey Schedule (SRSS) was administered to 2,828 boys and girls in middle schools in the United States and an Italian translation was administered to 342 boys and girls in middle schools in Northern Italy. An exploratory factor analysis using half the American data set was performed using maximum likelihood estimation with a promax rotation. This analysis produced a structural equation model with six interpretable latent variables. This analysis was confirmed by results demonstrating a good fit with the other half of the American sample and separately with the Italian sample. Scores for the six latent variables were constructed and information about the distribution of scores was obtained. Multiple comparisons of the means were performed by gender, within each national sample, for each of the six latent variables. American and Italian girls report obtaining greater enjoyment from a wider variety of school activities compared to American and Italian boys.     

Aging and the discrimination of 3-D shape from motion and binocular disparity

Two experiments evaluated the ability of younger and older adults to visually discriminate 3-D shape as a function of surface coherence. The coherence was manipulated by embedding the 3-D surfaces in volumetric noise (e.g., for a 55?% coherent surface, 55?% of the stimulus points fell on a 3-D surface, while 45?% of the points occupied random locations within the same volume of space). The 3-D surfaces were defined by static binocular disparity, dynamic binocular disparity, and motion. The results of both experiments demonstrated significant effects of age: Older adults required more coherence (tolerated volumetric noise less) for reliable shape discrimination than did younger adults. Motion-defined and static-binocular-disparity-defined surfaces resulted in similar coherence thresholds. However, performance for dynamic-binocular-disparity-defined surfaces was superior (i.e., the observers?? surface coherence thresholds were lowest for these stimuli). The results of both experiments showed that younger and older adults possess considerable tolerance to the disrupting effects of volumetric noise; the observers could reliably discriminate 3-D surface shape even when 45?% of the stimulus points (or more) constituted noise.     

Source memory for action in young and older adults: self vs. close or unknown others

The present study examines source memory for actions (e.g., placing items in a suitcase). For both young and older adult participants, source memory for actions performed by the self was better than memory for actions performed by either a known (close) or unknown other. In addition, neither young nor older adults were more likely to confuse self with close others than with unknown others. Results suggest an advantage in source memory for actions performed by the self compared to others, possibly associated with sensorimotor cues that are relatively preserved in aging.
