Examining impelling and disinhibiting factors for intimate partner violence in veterans

We examined correlates of intimate partner violence (IPV) in a military Veteran sample (N = 129) using Finkel's (2007) framework for understanding the interactions between impelling and disinhibiting risk factors. Correlates investigated included head contact events (HCEs), posttraumatic stress disorder (PTSD) symptoms, and antisocial features. Results indicated that antisocial features were significantly associated with IPV at the bivariate level. PTSD symptoms also were associated with IPV, but this association was marginally significant. Tests of moderation provided support for the expectation that HCEs would potentiate associations between antisocial features and IPV. HCEs also moderated the association between PTSD symptoms and IPV. However, contrary to expectations, the opposite pattern emerged such that PTSD symptoms were associated with a higher rate of IPV for those without a history of HCEs. Study findings have potentially important implications for furthering our understanding of the complex etiology of IPV in this population.     

All words are not created equal: expectations about word length guide infant statistical learning

Infants have been described as ‘statistical learners’ capable of extracting structure (such as words) from patterned input (such as language). Here, we investigated whether prior knowledge influences how infants track transitional probabilities in word segmentation tasks. Are infants biased by prior experience when engaging in sequential statistical learning? In a laboratory simulation of learning across time, we exposed 9- and 10-month-old infants to a list of either disyllabic or trisyllabic nonsense words, followed by a pause-free speech stream composed of a different set of disyllabic or trisyllabic nonsense words. Listening times revealed successful segmentation of words from fluent speech only when words were uniformly disyllabic or trisyllabic throughout both phases of the experiment. Hearing trisyllabic words during the pre-exposure phase derailed infants’ abilities to segment speech into disyllabic words, and vice versa. We conclude that prior knowledge about word length equips infants with perceptual expectations that facilitate efficient processing of subsequent language input.     

Boundary Disturbances and Eating Disorder Symptoms

Female graduate students in counseling and clinical psychology retrospectively rated maternal and paternal boundaries in their families of origin. Subscales of the Eating Disorders Inventory-3 were used to assess disordered eating, including drive for thinness, body dissatisfaction, bulimia symptoms, and overall risk. Results indicated that maternal enmeshment and maternal psychological control were related to disordered eating. Further, daughters who reported that their mothers shielded them from parents’ conflict and adult concerns were less likely to report drive for thinness or bulimic tendencies. With respect to paternal boundary problems, paternal infantilization (overprotection) was significantly related to daughters’ drive for thinness.     

PTSD Symptom Severity and Family Adjustment Among Female Vietnam Veterans

This study examined relations between posttraumatic stress disorder (PTSD) symptom severity and several family adjustment variables among a sample of 89 female Vietnam veterans and their male relationship partners. Findings revealed associations between PTSD symptom severity and measures of marital adjustment, family adaptability, family cohesion, parenting satisfaction, and psychological abuse. Results suggest that the presence of PTSD symptomatology may have important implications with regard to the family life of female Vietnam veterans.     

Executive and Attention Functioning Among Children in the PANDAS Subgroup

Evidence from past studies indicates that adults and children with Obsessive-Compulsive Disorder (OCD) and Tourette syndrome (TS) experience subtle neuropsychological deficits. Less is known about neuropsychological functioning of children and adolescents with a symptom course consistent with the PANDAS (Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal infection) subgroup of OCD and tics. To provide such information, we administered three tests of attention control and two of executive function to 67 children and adolescents (ages 5–16) diagnosed with OCD and/or tics and a symptom course consistent with the PANDAS subgroup and 98 healthy volunteers (HV) matched by age, sex, and IQ. In a paired comparison of the two groups, the PANDAS subjects were less accurate than HV in a test of response suppression. Further, in a two-step linear regression analysis of the PANDAS group in which clinical variables were added stepwise into the model and in the second step matching variables (age, sex, and IQ) were added, IQ emerged as a predictor of performance on this task. In the same analysis, ADHD diagnosis and age emerged as predictors of response time in a continuous performance task. Subdividing the PANDAS group by primary psychiatric diagnosis revealed that subjects with TS or OCD with tics exhibited a longer response time compared to controls than subjects with OCD only, replicating previous findings within TS and OCD. This study demonstrates that children with PANDAS exhibit neuropsychological profiles similar to those of their primary psychiatric diagnosis.     

Interpretation of facial expressions and social anxiety: Specificity and source of biases

Cognitive-behavioural models of social phobia (Clark & Wells, 1995; Rapee & Heimberg, 1997) propose that biased information processing contributes to the maintenance of social phobia. Given the importance of facial expressions in social interactions, recent investigations of these information-processing biases have increasingly used facial stimuli. The current study utilised schematic faces of emotional expressions to investigate interpretations of facial expressions and specific facial features in individuals with high and low social anxiety. Individuals with elevated social anxiety demonstrated biases in their perceptions of negative valence from the faces, whereas group differences were not observed for perceptions of activity or potency. Further, although the two groups generally utilised the same facial features to interpret facial expressions, the results suggested that individuals with high social anxiety may be more lenient in perceiving threat in faces than individuals without social anxiety.     

Using Kindergarten Language,Dialect Variation,and Child Behavior to Predict Second Grade Reading Ability in African American Children

Previous research has demonstrated mixed findings pertaining to the risk conferred by variation from Mainstream American English (MAE) for African American children in our education system. Based on the research on language, behavior, and reading, the present study sought to examine the relative and combined contributions of culturally appropriate measures of risk status for disordered language and density of dialect use and classroom behavior (both competencies and problems) in predicting reading ability in a sample of typically developing African American elementary school students. 53 African American Kindergartner's (27 boys, 26 girls) were followed up with two years later in 2nd grade. In Kindergarten, children were screened for density of dialect use and risk of language impairment; teachers rated each child on behavior, social/emotional adjustment, and academic performance. Reading achievement was assessed in 2nd grade. Risk for disordered language development was the best predictor of 2nd grade reading, outperforming density of dialect use. Positive classroom behaviors were more predictive of reading than negative behaviors. This research supports the notion that language, classroom behavior, and reading achievement are intertwined in a complex manner and that when designing interventions for one, the entire system must be considered.     

Sex, body-esteem and self-esteem

This study investigated the relationship between body-esteem and self-esteem among 215 young men and women (ages 18 to 25 years). It was expected that concern with weight and shape would be strongly associated with women's self-esteem, while men's self-esteem would be more closely linked to concerns about their fitness. Multiple regression analyses indicated that perceived attractiveness and the salience of weight and shape were significant predictors of self-esteem among women. Among men, the significant predictors of self-esteem were perceived attractiveness, body disparagement, and perceived strength and fitness.     

The face behind the mask: a developmental study

Faces are a rich and available source of social information, and the representation for faces is robust in adults (i.e. the face detection effect; Purcell & Stewart, 1988). The current study compared the developmental trajectory of the robustness of face perception against the trajectory for a non-face object. Participants (5-35 years old) were presented with rapid (17 and 33 millisecond) presentations of face and house stimuli and were instructed to identify the object category of the stimulus (face or house). There was an interaction between object type and age such that the developmental slope for face identification was steeper than the slope for house identification for the 17-millisecond presentation. These data show that faces are processed in a different way than a non-face object during the period from middle childhood through adolescence and adulthood, and this differential processing may involve the massive amount of exposure we have to faces.
