The Intermingling of Social and Evolutionary Psychology Influences on Hair Color Preferences

Hypotheses were tested as explanations for why men and women have specific hair color preferences for mates. Traditional evolutionary psychology approaches suggest that men should prefer light hair on women because it signals youth and health, while women should desire dark hair on men because it signals maturity and stability. Repeated exposure predicts people prefer the hair color on mates they are exposed to most frequently. Uniqueness implies that men and women should desire the least prevalent hair colors on potential mates because of its scarcity and rarity. Findings primarily support traditional evolutionary psychology predictions and occasionally the repeated exposure hypothesis, but not uniqueness predictions. Sex and regional differences indicate that social and evolutionary processes combine to influence hair color preferences.     

Structural-functional correlations between hippocampal volume and cortico-limbic emotional responses in depressed children

Although hippocampal atrophy and altered functional brain responses to emotional stimuli have been found in major depressive disorder (MDD), the relationship between the two is not yet well understood. The present study focused on children with and without a history of preschool onset MDD (PO-MDD) and directly examined the relations between hippocampal volume and functional brain activation to affect-eliciting stimuli. Children completed annual diagnostic assessments starting at preschool. When children were school-aged, high-resolution structural MRI and task-related functional MRI data were acquired from N = 64 nonmedicated children. During fMRI, subjects were shown emotional faces. Results from the total sample indicated that smaller bilateral hippocampal volumes were associated with greater cortico-limbic (e.g., amygdala, hippocampus, dorsolateral prefrontal cortex) activation to sad or negative faces versus neutral faces. Left hippocampal volume was negatively associated with the cortico-limbic activation in both the PO-MDD and healthy children. Right hippocampal volume was negatively correlated with amygdala responses in the PO-MDD group, but not in the healthy comparison group. These findings suggest that there may be important interrelationships between reduced hippocampal volume and hyperactivation of brain responses in children, both those with and those without a history of PO-MDD.     

Positive Organizational Outcomes Associated with a Penchant for Openness

The tension between scientific openness versus secrecy has existed for centuries (Hull 1985). However, both academics and practitioners have recently argued that openness by private firms has many positive attributes. The purpose of this research effort is to review the extant literature on openness and to develop hypotheses regarding its impact on organizational outcomes. We then use a unique database to test the idea with 87 companies. Our findings are that openness is beneficial to the firm from a science, technological, and financial perspective and, perhaps, to the employees from an ethical viewpoint. The managerial and societal implications are also discussed.     

Elevated amygdala response to faces following early deprivation

A functional neuroimaging study examined the long-term neural correlates of early adverse rearing conditions in humans as they relate to socio-emotional development. Previously institutionalized (PI) children and a same-aged comparison group were scanned using functional magnetic resonance imaging (fMRI) while performing an Emotional Face Go/Nogo task. PI children showed heightened activity of the amygdala, a region that supports emotional learning and reactivity to emotional stimuli, and corresponding decreases in cortical regions that support perceptual and cognitive functions. Amygdala activity was associated with decreased eye-contact as measured by eye-tracking methods and during a live dyadic interaction. The association between early rearing environment and subsequent eye-contact was mediated by amygdala activity. These data support the hypothesis that early adversity alters human brain development in a way that can persist into childhood, and they offer insight into the socio-emotional disturbances in human behavior following early adversity.     

The impact of checklist-based training on teachers' use of the zone defense schedule

We assessed the impact of checklist-based training on teaching teams' use of the zone defense schedule. Three teaching teams (lead teacher plus 2 assistant teachers) in an inclusive early childhood program participated. A multiple baseline design across teams was used to determine whether accurate implementation of the zone defense schedule increased when checklist-based training was provided. All teaching teams reached the preestablished criterion, implementing a minimum of 80% of checklist items accurately for 3 consecutive observations.     

Footwear and locomotor skill performance in preschoolers

The effect of footwear on locomotor skill performance was examined. 12 children (4 boys, 8 girls; M age = 56.3 mo., SD = 3.3) served as participants. Participants were randomly assigned to perform the locomotor subscale of Ulrich's Test of Gross Motor Development in two shoe conditions (Condition 1: Stride Rite athletic shoes, and Condition 2: flip flop sandals). Children scored significantly higher when wearing athletic shoes than flip-flop sandals. This finding is relevant for motor performance and safety in physical education and movement programs.     

Families created through surrogacy: mother-child relationships and children's psychological adjustment at age 7

Each year, an increasing number of children are born through surrogacy and thus lack a genetic and/or gestational link with their mother. This study examined the impact of surrogacy on mother-child relationships and children's psychological adjustment. Assessments of maternal positivity, maternal negativity, mother-child interaction, and child adjustment were administered to 32 surrogacy, 32 egg donation, and 54 natural conception families with a 7-year-old child. No differences were found for maternal negativity, maternal positivity, or child adjustment, although the surrogacy and egg donation families showed less positive mother-child interaction than the natural conception families. The findings suggest that both surrogacy and egg donation families function well in the early school years.     

Methodological, ethical, and legal considerations in drug court research

Since their inception in the late 1980s, drug courts have become the most prevalent specialty court in the United States. A large body of outcome research conducted over the past two decades has demonstrated that drug courts effectively reduce drug use and criminal recidivism, which has led to the rapid proliferation of these courts. Importantly, drug court research has flourished despite the many challenges faced by researchers when working with a vulnerable population of justice-involved substance users. In this article, we highlight the most common methodological, ethical, and legal challenges encountered in drug court research, and discuss ways in which researchers can overcome these challenges to conduct high-quality research. Drug court research exemplifies how rigorous empirical investigation can be accomplished in the criminal justice system, and it can serve as a useful model for researchers working in other parts of the judicial system.     

Relative Influence of Professional Counseling Journals

The authors used social network analysis of citation data to study the flow of information and relative influence of 17 professional counseling journals. Although the Journal of Counseling & Development ranked very highly in all measures of journal influence, several division journals emerged as key players in the flow of information within the counseling profession. Results highlight the many facets of journal influence and the fallacy of using single measures, such as journal impact factor, to rank professional counseling journals.     

Internationalizing counselling: A Southeast Asian perspective

To learn about our Southeast Asian colleagues’ views on internationalizing counselling psychology to Asian cultures, we interviewed eight counselling psychologists who had received their doctoral training in the United States. Four of the participants were currently practicing and teaching in their native countries and four in the United States. Using the basic principles of Grounded Theory [Glaser, B., & Strauss, A. (1967). The discovery of grounded theory. Chicago, IL: Aldine.], we derived two themes from the data: (1) major assumptions in US counselling psychology that may limit its transferability to Southeast Asian cultures and (2) practices in learning, training, and cultural adjusting for future development and internationalization of counselling psychology. The participants emphasized the need for indigenization and knowledge sharing in the efforts to internationalize counselling psychology.
