Subitizing and counting in typical and atypical development

Enumeration performance in standard dot counting paradigms was investigated for different age groups with typical and atypically poor development of arithmetic skills. Experiment 1 showed a high correspondence between response times and saccadic frequencies for four age groups with typical development. Age differences were more marked for the counting than the subitizing range. In Experiment 2 we found a discontinuity between subitizing and counting for dyscalculic children; however, their subitizing slopes were steeper than those of typically developing control groups, indicating a dysfunctional subitizing mechanism. Across both experiments a number of factors could be identified that affect enumeration in the subitizing and the counting range differentially. These differential patterns further support the assumption of two qualitatively different enumeration processes.     

Which preventive interventions effectively enhance depressed mothers' sensitivity? A meta‐analysis

Improving depressed mothers' sensitivity is assumed to be a key element in preventing adverse outcomes for children of such mothers. This meta‐analysis examines the short‐term effectiveness of preventive interventions in terms of enhancing depressed mothers' sensitivity toward their child and investigates what type of intervention is most effective. Thirteen interventions, reported in 10 controlled outcome studies, met the inclusion criteria (N = 918). Meta‐analytic results showed a small to medium, significant mean effect size (g = 0.32) with large variation in individual effect sizes (?0.56–1.76). Interventions including baby massage were highly effective in improving maternal sensitivity (g = 0.85). In contrast, individual therapy for the mother proved ineffective in terms of improving maternal sensitivity (g = ?0.00). Two other significant predictors of greater effect sizes were the inclusion of a support group and the use of a higher number of intervention methods; however, the significance of these results was largely accounted for by one single study. Our meta‐analysis confirms that depressed mothers' sensitivity can be improved by preventive intervention and suggests that baby massage may be an effective intervention method to evoke short‐term changes in maternal sensitivity. It is unclear whether these changes are maintained over time.     

Physical self-concept and self-esteem mediate cross-sectional relations of physical activity and sport participation with depression symptoms among adolescent girls.

The authors tested whether physical self-concept and self-esteem would mediate cross-sectional relations of physical activity and sport participation with depression symptoms among 1,250 girls in 12th grade. There was a strong positive relation between global physical self-concept and self-esteem and a moderate inverse relation between self-esteem and depression symptoms. Physical activity and sport participation each had an indirect, positive relation with global physical self-concept that was independent of objective measures of cardiorespiratory fitness and body fatness. These correlational findings provide initial evidence suggesting that physical activity and sport participation might reduce depression risk among adolescent girls by unique, positive influences on physical self-concept that operate independently of fitness, body mass index, and perceptions of sports competence, body fat, and appearance.     

Decreasing overt discrimination increases covert discrimination: Adverse effects of equal opportunities policies

Building on the moral licensing literature, this paper examines whether highlighting the successful implementation of an equal opportunities policy in a company leads to covert forms of discrimination in hiring decisions (i.e., expressing a preference for a white candidate over an equally qualified black/Moroccan candidate in an ambiguous context). Furthermore, moral self‐image is indirectly tested as a possible underlying mechanism. Two scenario studies first revealed that covert discrimination is more likely after highlighting a successful implementation of an equal opportunities policy in the company (study 1) and that elevated levels of moral self‐image are related to covert discrimination (study 2). Subsequently, a field study revealed that the presence of successful equal opportunities policies positively related to employees’ moral self‐image (study 3).     

Hypnotic susceptibility in patients with conversion disorder

Conversion disorder has been associated with hypnotic susceptibility for over a century and is currently still believed to be a form of autohypnosis. There is, however, little empirical evidence for the relation between hypnotic susceptibility and conversion symptoms. The authors compared 50 patients with conversion disorder with 50 matched control patients with an affective disorder on measures of hypnotic susceptibility, cognitive dissociation, and somatoform dissociation. Conversion patients were significantly more responsive to hypnotic suggestions than control patients. In addition, conversion patients showed a significant correlation between hypnotic susceptibility and the number of conversion complaints. These results provide the first evidence of a relationship between hypnotic susceptibility and the presence and number of conversion symptoms.     

Predicting changes in children's self-perceptions of academic competence: a naturalistic examination of evaluative discourse among classmates

Classroom discourse was examined as a predictor of changes in children's beliefs about their academic capabilities. Kindergarten, first-grade, and second-grade students (N = 106) participated in 2 waves of data collection, approximately 1 year apart. During the 1st year of the study, children's verbal interactions with their classmates were observed and recorded. Children rated their self-perceptions of academic competence during the 1st and 2nd years. Analyses revealed that changes over time in children's competence perceptions could be predicted from the types of statements that children made and had directed toward them by classmates. Examining sequences of child and classmate statements proved helpful in explaining the observed changes in children's perceptions of competence.     

Selective orienting of attention to masked threat faces in social anxiety

The aims of the study were two-fold: to examine whether previous evidence of a pre-attentive bias for masked threat faces in anxious individuals could be replicated, and to assess the relationship between the predicted bias and measures of trait and social anxiety. Pairs of face stimuli were briefly displayed and masked in a modified version of the visual probe task. Results indicated that high anxious individuals were faster to respond to probes occurring in the spatial location of masked threat rather than neutral faces; consistent with their attention being automatically captured by sub-threshold threat cues. Furthermore, this vigilance effect for masked threat faces appeared to be primarily a function of social anxiety and social avoidance, rather than trait anxiety. It was also more apparent when threat faces were presented in the left visual field, suggestive of right hemisphere involvement.     

Differentiating overreporting and extreme distress: MMPI-2 use with compensation-seeking veterans with PTSD

This purpose of this study was to examine overreporting on the Minnesota Multiphasic Personality Inventory-2 (MMPI-2; Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989) in compensation-seeking veterans with posttraumatic stress disorder (PTSD). A sample of veterans tested during a V.A. hospital compensation and pension exam were given the MMPI-2 and measures of PTSD, depression, and combat exposure. Veteran's MMPI-2s were only included in the analyses if their profile was extremely exaggerated, as measured by an F scale T score above 80, did not elevate the MMPI-2 VRIN and TRIN scales, and had a primary diagnosis of PTSD (n = 127). Using the Infrequency-Psychopathology, F(p), scale to distinguish overreporting from distress, it was found that 98 veterans elevated profiles due to distress, whereas 29 elevated due to overreporting, F(p) below and above 7, respectively. Differences between groups on MMPI-2 clinical scales and the other measures were assessed. Implications of these findings for assessing veteran response style and using the MMPI-2 with a PTSD population are discussed.     

Selective attention to angry faces in clinical social phobia

This study investigated the time course of attentional responses to emotional facial expressions in a clinical sample with social phobia. With a visual probe task, photographs of angry, happy, and neutral faces were presented at 2 exposure durations: 500 and 1250 ms. At 500 ms, the social phobia group showed enhanced vigilance for angry faces, relative to happy and neutral faces, in comparison with normal controls. In the 1250-ms condition, there were no significant attentional biases in the social phobia group. Results are consistent with a bias in initial orienting to threat cues in social anxiety. Findings are discussed in relation to recent cognitive models of anxiety disorders.
