The effect of prenatal androgen exposure on the development of neural reactivity systems: A study of the HEXACO Personality Inventory

The ratio of the lengths of the second and fourth digits of hands (2D:4D) seems to vary as a function of systematic differences in prenatal androgen exposure (Hönekopp & Watson, 2010). The 2D:4D ratio has been shown to be related to a variety of personality attributes. This study predicted that 2D:4D would covary with scores on the emotionality dimension of the six-facet HEXACO personality assessment, due to emotionality’s relationship with neural reactivity systems controlled by the amygdala (Hines, Allen, & Gorski, 1992), but that 2D:4D would relate to no other facet. Consistent with hypotheses, data showed that men had smaller ratios than women on both the right, t(405) = 2.84, p < .05, d = .28, and left hands, t(405) = 4.51, p < .05, d = .45, and the relationship between 2D:4D and emotionality was outside of sampling error of zero, r = .18, p < .001. Additionally, 2D:4D was unrelated to the remaining HEXACO facets. Findings suggest that prenatal testosterone exposure has an organizing effect on personality traits.     

Primary Trauma of Female Partners in a Military Sample: Individual Symptoms and Relationship Satisfaction

Research traditionally has focused on the development of symptoms in those who experienced war trauma directly but overlooked the impact of trauma in the partners of soldiers. The current study reports data from 45 couples where the male partners were Army soldiers who recently returned from deployments to Iraq (Operation Iraqi Freedom) or Afghanistan (Operation Enduring Freedom). Results from this study indicated that female partner primary trauma, particularly trauma related to PTSD re-experiencing and arousal symptoms, has an influence on levels of relationship satisfaction, both for female partners and soldiers.     

Parenting Practices of Anxious and Nonanxious Mothers: A Multi-Method,Multi-Informant Approach

Anxious and nonanxious mothers were compared on theoretically derived parenting and family environment variables (i.e., overcontrol, warmth, criticism, anxious modeling) using multiple informants and methods. Mother-child dyads completed questionnaires about parenting and were observed during an interactional task. Findings reveal that, after controlling for race and child anxiety, maternal anxiety was associated with less warmth and more anxious modeling based on maternal-report. However, maternal anxiety was not related to any parenting domain based on child-report or independent observer (IO) ratings. Findings are discussed in the context of the impact of maternal anxiety on parenting and suggest that child, rather than maternal, anxiety may have a greater influence on maternal behavior.     

Effects of the Copy-Cover-Compare Strategy on Acquisition,Maintenance, and Generalization of Spelling Sight Words for Elementary Students With Attention Deficit/Hyperactivity Disorder

Students with attention deficit/hyperactivity disorder (ADHD) often struggle with spelling. Research shows this population benefits from self-management interventions, structured practice opportunities, and immediate feedback—all components of the copy-cover-compare strategy. This empirical investigation used a multiple-baseline experimental design to determine the effects of the copy-cover-compare strategy on acquisition, generalization, and maintenance of spelling words for four students with ADHD in Grades 1 through 3. Results showed a functional relation between copy-cover-compare and mastery, maintenance, and generalization of three sets of spelling words for each student. Limitations, implications for practice, and suggestions for future research are discussed.     

Concordance Between Measures of Anxiety and Physiological Arousal Following Treatment of Panic Disorder in Adolescence

This study examined the concordance (or synchrony/desynchrony) between adolescents' self-reports of anxiety and physiological measures of arousal (heart rate) both prior to and after treatment for panic disorder. Results indicated a decline in reported subjective units of distress (SUDS) for the treatment group only at the post-treatment measurement for two of three tasks. Within the treatment group, heart rate changes during the Behavioral Approach Test (BAT) were observed following treatment for one task only. Implications of this apparent desynchrony between self-report and physiological measures in adolescent panic disorder are discussed, with cognitive changes in participants' perception of anxiety after treatment suggested as an important factor in recovery.     

A Review of: “Bear,G. G. (2010). School Discipline and Self-Discipline: A Practical Guide to Promoting Prosocial Student Behavior.”

Previous research demonstrates that children with attention-deficit/hyperactivity disorder (ADHD) can experience social difficulties. Therefore, the current study examined the effects of cross-age peer coaching on social behaviors of first graders with significant symptoms of ADHD using a multiple baseline design. Four students who met criteria for ADHD participated, along with four third- or fourth-grade coaches without ADHD. Coaching pairs met each morning to establish a goal for the younger child to meet during free time. Although results were variable, findings suggested that the cross-age coaching program led to decreases in negative social behavior, and was highly acceptable to participants.
