The warpy thoughts scale: a new 20-item instrument to measure dysfunctional attitudes

Cognitive theories of psychopathology propose that specific negative cognitive schema held by individuals can increase their likelihood of experiencing depressive episodes. While it has been argued that such dysfunctional attitudes are state measures that occur primarily during periods of depression, a range of research has supported the view that holding dysfunctional attitudes is ongoing, persisting prior to and following depressive episodes. To date, the need for a parsimonious measure of dysfunctional attitudes has not been well addressed. Using data provided by 4545 participants in a free on-line cognitive behavioural therapy program, MoodGYM, we have developed the Warpy Thoughts Scale (WTS), a 20-item instrument measuring dysfunctional attitudes. This scale provides 3 first order factors (Relationships, Achievements and Entitlements) and a higher order factor, Warpy Thoughts, from which a Warpy Thoughts score can be obtained. Confirmatory factor analyses on this model indicated that it provides robust results for men and women and for individuals in a wide range of ages. WTS scores were moderately correlated with levels of depressive and anxiety symptoms (0.39 and 0.40, respectively) and explained up to one-fifth of the variance of these mental health measures. Further validation of the WTS against other measures of dysfunctional thoughts is required.     

Infants' symbolic comprehension of actions modeled with toy replicas

While very young children's understanding of objects as symbols for other entities has been the focus of much investigation, very little is known concerning the emergence of comprehension for symbolic relations among actions modeled with toy replicas and their real counterparts. We used videotaped depictions of real actions in a preferential looking task to assess toddlers' ability to comprehend such connections for action categories aligned with familiar object concepts. Across two experiments, 16- and 18-month-olds provided no evidence of understanding such relations, even when action categories were highlighted with verbal prompts. Among 24- and 26-month-olds, comprehension of relations between certain actions modeled with toys and videos of their real-world counterparts began to emerge, independent of expressive vocabulary size. Implications of our results for theoretical conclusions drawn from use of the generalized imitation procedure to study early conceptual development are discussed.     

On the role of preference in response competition

A duration-based preference assessment identified items that matched and did not match the sensory consequences hypothesized to maintain stereotypy. When evaluated in treatment, these items effectively competed with the occurrence of stereotypy, regardless of their sensory properties. It is suggested that relative preference, as measured in duration-based assessment, can be as significant as type of stimulation produced in interventions that reduce automatically reinforced problem behavior.     

The role of perception, language, and preference in the developmental acquisition of basic color terms

When learning basic color vocabulary, young children show a selective delay in the acquisition of brown and gray relative to other basic color terms. In this study, we first establish the robustness of this finding and then investigate the extent to which perception, language, and color preference may influence color conceptualization. Experimental tasks were designed to measure different aspects of perceptual color processing (discrimination and saliency), color preference and objective counts of color term frequency in preschool-directed language (books and mothers' speech) were used to compare the acquisition of three groups of colors: primary colors, secondary colors (orange, pink, and purple) that appear at the same time as the primary colors, and secondary colors (brown and gray) that appear late. Although our results suggest that perception does not directly shape young children's color term acquisition, we found that children prefer brown and gray significantly less than basic colors and that these color terms appear significantly less often in child-directed speech, suggesting that color preference, linguistic input, and developing color cognition may be linked.     

A COMPARISON OF SEMANTIC‐ AND MNEMONIC‐BASED VOCABULARY‐LEARNING STRATEGIES

Fourth‐ and fifth‐grade students were taught the meanings of new vocabulary items according to one of three instructional strategies. Two of the strategies were semantic‐based (contextual analysis and semantic mapping), and the other strategy was mnemonic‐based (the keyword method). Consistent with recent research findings, the keyword method facilitated students’ recall of the vocabulary items’ definitions, and this was true in both higher‐ and lower‐achieving subject populations. In the higher‐achieving sample, the keyword method was also superior to the contextual analysis strategy on two vocabulary‐usage tests, one that was administered on the day immediately following instruction and one that was administered a week later. Mean performance on a one‐week delayed definition‐matching test was statistically equivalent in the three conditions, although in the higher‐achieving sample a reliably higher proportion of keyword subjects than contextual analysis subjects attained perfect scores on that test. No significant difference between the two semantic‐ based strategies was found on any of the dependent measures. Implications of the results and suggestions for future research are included in the discussion.     

Implications of Identification with Parents and Parents' Acceptance for Adolescent and Young Adult Self-esteem

Although several authors have suggested that youths' identification with their parents plays an important role in how they come to evaluate themselves, this hypothesis has not been explored empirically in longitudinal research. Using prospective data from a representative community sample, we tested whether the association between adolescents' identification with mother and father and subsequent gains in global self-esteem would hinge on the parent's acceptance or rejection of the adolescent. Results showed that male adolescents' self-esteem consistently improved the more they identified with their parents. Among female adolescents, the change in self-esteem associated with parental identification depended on the parent's evaluation of them, suggesting that identifying with a rejecting parent presents a particular vulnerability for low self-esteem in young women.     

Understanding spatial transformations: similarities and differences between mental rotation and mental folding

Mental rotation and mental folding, two widely used measures of spatial ability, both require the dynamic spatial transformation of objects with respect to their internal spatial structure. Traditionally, however, these two skills have been considered quite distinct, based primarily on factor analyses of psychometric data. This paper reviews the similarities and differences between mental rotation and mental folding from a variety of perspectives, including their definitions, component cognitive processes, neurological bases, developmental trajectories, malleability, predictive validity, and psychometric properties. We conclude that mental rotation and mental folding are similar in many respects. However, the tasks differ in whether they require rigid or non-rigid transformations of objects. In addition, mental rotation shows robust sex-related differences whereas mental folding does not. We also identify specific questions for which research is lacking.     

Victims of Intimate Partner Violence: Arrest Rates Across Recent Studies

Efforts by women's rights activists, concomitant with results of research studies and court cases, have prompted legal reforms in public policy that include recently implemented mandatory arrest and prosecution laws. A review of the recent research since the advent of these laws suggests that arrests of women have increased by 25–35%, while the most liberal estimate is that only 1–7% of all IPV arrests are of actual female primary batterers, suggesting that victim arrests are on the rise. Various factors contribute to officers arresting not only primary batterers but victims as well, creating confusion and resentment over mandatory arrest policies. The negative implications of this arrest pattern are far-reaching because errant arrests hold negative consequences for victims, including legal, financial, employment, and familial repercussions.
