Early contributions to infants’ mental rotation abilities

Some cognitive abilities exhibit reliable gender differences, with females outperforming males in specific aspects of verbal ability, and males showing an advantage on certain spatial tasks. Among these cognitive gender differences, differences in mental rotation are the most robust, and appear to be present even in infants. A large body of animal research suggests that gonadal hormones, particularly testosterone, during early development could contribute to this gender difference in mental rotation. Also, substantial evidence supports an influence of socialization on mental rotation performance. The present study investigated the relationship of two types of factors, early postnatal testosterone exposure and parental attitudes about gender, to mental rotation performance in 61 healthy infants (29 males, 32 females). We measured salivary testosterone at two time points: 1–2.5 months of age and 5–6 months of age. Infants’ mental rotation performance and parents’ attitudes about gender were assessed at 5–6 months of age. As predicted, testosterone concentrations were significantly higher in boys than girls in early infancy (d = 0.54), and boys performed significantly better than girls on mental rotation (d = 0.64). A significant positive correlation between testosterone at age 1–2.5 months and mental rotation was found only in boys (r = 0.50, p = .01). A significant negative correlation between parents’ gender‐stereotypical attitudes and mental rotation performance was found only in girls (r = ?.57, p = .002). These findings suggest that the early postnatal testosterone surge (also known as “mini‐puberty”) may have organizational influences on mental rotation performance in boys, and that parents may influence their daughters’ mental rotation abilities beginning very early in life.     

A Comparison of Wages by Gender and Region of Origin for Newly Arrived Refugees in the USA

The resettlement model supported by the US government aims to help recently arrived refugees achieve economic self-reliance within the first 90 to 180 days of arrival. In addition to the challenges they face in adapting to their new locations, however, refugees enter a US labor market characterized by preexisting wage disparities based on race and gender. Meanwhile, recent changes in US refugee and immigration policies have infused debates over nationalism, Islamophobia, and the economics of resettlement. In this context, it is critical to assess whether refugees face wage discrimination that may affect their ability to become economically self-reliant. Drawing on the International Rescue Committee’s administrative data on refugee resettlement, we examine the extent to which starting wages for newly arrived refugees differ by region of origin and gender. The study found consistent gender pay gaps among the majority of new arrivals. The study also identified lower wages for refugees arriving from sub-Saharan Africa, Latin America, and the Caribbean compared to other regions. These trends suggest a need for more consistent agency monitoring of employment placement, and the development of strategies to ensure more equitable employment outcomes for refugees.     

Sex Differences and Similarities in Video Game Experience,Preferences, and Self-Efficacy: Implications for the Gaming Industry

As computer technology continues to pervade every facet of life, the study of video game playing becomes more relevant. Studies show that sex differences continue to exist between men and women, boys and girls, in video game experience, favoring males. Few studies show any overlap in preferences between young men and women in their video gaming choices. The current study surveyed over 2,000 college undergraduates for video game experience, preferences, and self-efficacy. Although it was found that men play video games more often, have had more experience, and feel more confident in their game playing ability, a moderate female gaming population was found to exist, who also play video games regularly. Almost as many similarities as differences were found between men and women in their gaming preferences. Suggestions and implications for the video game industry are discussed.     

The Minnesota Multiphasic Personality Inventory-2 Restructured Form in National Guard soldiers screening positive for posttraumatic stress disorder and mild traumatic brain injury

The Minnesota Multiphasic Personality Inventory-2 Restructured Form (MMPI-2 RF) was administered to 251 National Guard soldiers who had recently returned from deployment to Iraq. Soldiers were also administered questionnaires to identify posttraumatic stress disorder (PTSD) and mild traumatic brain injury (mTBI). On the basis of responses to the screening instruments, the National Guard soldiers who produced a valid MMPI-2 RF were classified into four groups: 21 soldiers who screened positive for PTSD only, 33 soldiers who screened positive for mTBI only, 9 soldiers who screened positive for both conditions, and 166 soldiers who did not screen positive for either condition. Results showed that the MMPI-2 RF was able to differentiate across the groups with the MMPI-2 RF specific problem scale Anxiety adding incrementally to MMPI-2 Restructured Clinical scales in predicting PTSD. Both MMPI-2 RC1 (Somatic Complaints) and MMPI-2 RF head pain complaints predicted mTBI screen but did not add incrementally to each other. Of note, all of the MMPI-2 RF validity scales associated with overreporting, including Symptom Validity-Revised (FBS-r), were not significantly elevated in the mTBI group. These findings support the use of the MMPI-2 RF in assessing PTSD in non-treatment-seeking veterans. This further suggests that a positive screen for mTBI alone is not associated with significant emotional disturbance.     

Effects of diurnal variation and caffeine consumption on Test of Variables of Attention (TOVA) performance in healthy young adults

The Test of Variables of Attention (TOVA) is a continuous performance test (CPT) that assesses attention, impulsivity, and processing speed. CPTs are used in the assessment of attention-deficit/hyperactivity disorder (ADHD) in children, but more young adults are being assessed for ADHD as well. The TOVA norms are based on a standardization sample that was tested early in the day, and any TOVA administered after 1:00 p.m. will be flagged as potentially invalid. Whereas the testing time recommendations make sense for pediatric samples, it is unclear whether they are appropriate for young adults in college, who typically show significant phase delay in their diurnal rhythms. In addition, many college students consume large amounts of caffeine, and it is unclear how caffeine consumption affects TOVA performance. The current study examined the impact of time of day, self-reported diurnal preference, and caffeine consumption on TOVA performance in a double-blind, placebo-controlled experiment with healthy college students. There was evidence of diurnal variation on average response time and impulsivity but not on overall ADHD score, with participants tested in the afternoon responding faster but making more commission errors than did participants tested in the morning. Caffeine consumption led to significantly faster response times, but only for participants who typically consumed relatively little caffeine. We conclude that the TOVA can be administered to young adults outside the recommended time constraints without compromising the validity of test score interpretation but that the caffeine consumption of participants should be closely monitored.     

Teachers’ Knowledge of Evidence-Based Interventions and Available School Resources for Children with Emotional and Behavioral Problems

School professionals need to be prepared to support children with emotional and behavioral problems. Teachers in particular should be aware of the resources provided by their school as well as the evidence-based practices available to support children with behavioral problems. This study explored general education teachers’ knowledge of 10 evidence-based interventions as well as resources and data collected at their schools to support children with mental health problems. Participants included 239 general educators from 5 school districts. Overall, most teachers had not heard of 9 out of 10 of the evidence-based programs presented. Teachers were also not sure whether their schools provided specific assessments and interventions to support children. One particularly noteworthy finding was that 57% of teachers were not sure whether their schools provided functional behavioral assessment and intervention planning. Findings illuminate a need for continued work in this area.     

The Impact of Child and Family Team Composition on Wraparound Fidelity: Examining Links Between Team Attendance Consistency and Functioning

Although a growing body of literature has examined wraparound implementation and fidelity, child and family team (CFT) members’ levels of participation and the consistency of their attendance have not been systematically examined. This study explored the relationship between CFT member attendance consistency and the fidelity of wraparound team level implementation processes in a System of Care (SOC). Specifically, utilizing Participant Rating Form (PRF) data collected from caregivers, facilitators, youth, supportive persons, and service providers, as well as meeting attendance records, the relationship between team attendance consistency and fidelity of wraparound implementation was explored. Records for 88 teams, with a total of 2,643 members’ ratings of CFT meetings between 2004 and 2009, were examined. Analyses indicate that the structural team factors of attendance consistency and mean team members present relate to CFT members’ ratings of team functioning and the degree to which meeting processes are consistent with the tenets of wraparound. Team attendance variables related to the views of meeting functioning by facilitators, service providers, and caregivers, the individuals most often responsible for implementation of the plan of care, but not ratings by youth or supportive persons. These findings have implications for policy and the successful implementation of wraparound, underscoring the relevance of attending to and tracking the composition of the CFT and more actively encouraging consistent meeting attendance. Results also highlight the need to measure structural variables that may have salience in fidelity and implementation assessments and, more globally, the effectiveness of SOCs.     

The Development of a Methodology for Examining the Process of Family Communication of Genetic Test Results

It is important to study communication processes in families where members are undergoing testing for genetic conditions because the information received from such testing is crucial not just to the individual concerned but also to other members of the biological family. This topic has received little research attention, in part because of the complexities of methodology required. In this paper we present the development of a method specifically designed for the examination of the content and process of communication of genetic information in families. The method aims to maximize ecological validity as far as is possible. We describe how participants and other family members are recruited and how data were collected. We outline three main data analytic strategies: a graphic to show how genetic information changes as it flows from clinic and through the family, an intensive qualitative analysis of the meaning and impact of the genetic information to different family members, and an informative genogram which plots key family dynamics. This method will be illustrated in relation to a study of ten family-groups where one individual has been found to carry a genetic mutation predisposing them to hereditary breast and ovarian cancer.     

Visual search in scenes involves selective and nonselective pathways

How does one find objects in scenes? For decades, visual search models have been built on experiments in which observers search for targets, presented among distractor items, isolated and randomly arranged on blank backgrounds. Are these models relevant to search in continuous scenes? This article argues that the mechanisms that govern artificial, laboratory search tasks do play a role in visual search in scenes. However, scene-based information is used to guide search in ways that had no place in earlier models. Search in scenes might be best explained by a dual-path model: a 'selective' path in which candidate objects must be individually selected for recognition and a 'nonselective' path in which information can be extracted from global and/or statistical information.
