Frequency and Intensity of Emotional Expressiveness and Preschool Children’s Peer Competence

Children’s emotional expressiveness with peers was examined as a predictor of social competence. Data were collected from 122 preschool children (57 boys, 65 girls; 86 European American, 9 African American, 17 Hispanic, and 10 other ethnicity) over a period of two?years. Observations of children’s peer interactions in Year 1 were coded for frequency and intensity of happiness, anger, sadness, and fear. Sociometric interviews and teacher ratings provided assessments of children’s peer competence in both Years 1 and 2. Frequent expression of happiness in Year 1 predicted higher social competence scores in Year 2, whereas frequent anger in Year 1 predicted lower peer competence Year 2. More intense anger and sadness in Year 1 predicted lower peer social competence scores in Year 2. Frequency and intensity of emotional expressiveness in Year 1 accounted for unique variance in peer competence in Year 2.     

Radical embodied cognitive science and problems of intentionality

Radical embodied cognitive science (REC) tries to understand as much cognition as it can without positing contentful mental entities. Thus, in one prominent formulation, REC claims that content is involved neither in visual perception nor in any more elementary form of cognition. Arguments for REC tend to rely heavily on considerations of ontological parsimony, with authors frequently pointing to the difficulty of explaining content in naturalistically acceptable terms. However, many classic concerns about the difficulty of naturalizing content likewise threaten the credentials of intentionality, which even advocates of REC take to be a fundamental feature of cognition. In particular, concerns about the explanatory role of content and about indeterminacy can be run on accounts of intentionality as well. Issues about explanation can be avoided, intriguingly if uncomfortably, by dramatically reconceptualizing or even renouncing the idea that intentionality can explain. As for indeterminacy, Daniel Hutto and Erik Myin point the way toward a response, appropriating an idea from Ruth Millikan. I take it a step further, arguing that attention to the ways that beliefs’ effects on behavior are modulated by background beliefs can help illuminate the facts that underlie their intentionality and content.

     

Age-related differences in switching between cognitive tasks: does internal control ability decline with age?

The present study tested the hypothesis that older adults establish a weaker task set than younger adults and therefore rely more on stimulus-triggered activation of task sets. This hypothesis predicts that older adults should have difficulty with task switches, especially when the stimuli-responses are associated with multiple, competing tasks. Weak task preparation, however, could actually benefit older adults when performing an unexpected task. The authors tested this prediction in Experiment 1 using a repeating AABB task sequence, with univalent and bivalent stimuli intermixed. On some univalent trials, participants received an unexpected task. Contrary to the authors' predictions, expectancy costs were not smaller for older adults. Similar findings were obtained in Experiments 2 and 3, in which the authors used a task-cueing paradigm to more strongly promote deliberate task preparation. The authors found no disproportionate age effects on switch costs but did find age effects on bivalence costs and mixing costs. The authors conclude that older adults do experience extra difficulty dealing with stimuli associated with 2 active tasks but found no evidence that the problem specifically stems from an increased reliance on bottom-up task activation rather than top-down task preparation.     

Comorbidity of Pediatric Obsessive–Compulsive Disorder and Anxiety Disorders: Impact on Symptom Severity and Impairment

This study explored the impact of comorbidity on symptom severity and treatment outcome in a sample of 75 pediatric Obsessive–Compulsive Disorder (OCD) patients. Forty received cognitive–behavioral therapy (CBT). Overall, 56% had a comorbid disorder. Results revealed that youth with comorbid disorders (anxiety or otherwise) endorsed significantly more anxiety symptoms than youth with OCD only. Youth with comorbidities instead of or in addition to anxiety exhibited more severe OCD symptoms than youth with OCD alone or an anxiety-only comorbidity. Youth in the comorbidities instead of or in addition to anxiety group had the poorest CBT response relative to the other groups. These results suggest that relative to those with OCD alone or with an anxiety disorder comorbidity, youth with comorbidities instead of or in addition to anxiety have a differing clinical presentation (e.g., more severe symptoms) and worse psychotherapy outcome.

Recalled Childhood Teasing among Non-Clinical, Non-College Adults

This study examined the psychometric properties of the Teasing Questionnaire—Revised (TQ-R) in a non-clinical community sample of adults. The TQ-R, Brief Fear of Negative Evaluation Scale, Beck Depression Inventory-II, and UCLA Loneliness Scale were administered to 355 adults, aged 18–86 years. Confirmatory factor analysis showed the five-factor teasing model proposed by Storch et al. (Journal of Anxiety Disorders, 18, 665–679, 2004c) was not a good fit for these data. A three-factor model consisting of Academic, Social, and Appearance factors was found through exploratory analyses [termed the Teasing Questionnaire—Revised—Short Form (TQ-R-S)]. Internal consistency was good for the TQ-R-S Total Score and resultant TQ-R-S Academic, Social, and Appearance factors. TQ-R-S scores were directly correlated with current psychosocial functioning with correlations of a small to medium effect size. These results provide evidence that teasing during childhood is linked to later symptoms of depression, anxiety, and loneliness.     

Using the 4/5ths Rule as an Outcome in Regression Analyses: A Demonstrative Simulation

The adverse impact associated with personnel practices is an important issue for personnel psychologists. The purpose of this simulation study is to demonstrate the consequences of using the 4/5ths rule and the adverse impact ratio in analyses designed to predict adverse impact from human resource management (HRM) strategies. Results show that increasing (1) the total number of selections made and (2) the minority representation in the candidate pool may influence adverse impact differently depending on how adverse impact is measured. Specifically, using the 4/5ths rule as an outcome in logistic regression analyses led to unexpected findings regarding the effectiveness of HRM strategies designed to reduce adverse impact. On the other hand, using the adverse impact ratio as an outcome in linear regression analyses produced to intuitive findings.
