Gender and Theory of Mind in Preschoolers’ Group Effort: Evidence for Timing Differences Behind Children’s Earliest Social Loafing

This study explored mental state reasoning within the context of group effort and possible differences in development between boys and girls. Preschool children (59 girls, 47 boys) were assessed for theory of mind (ToM) ability using classic false belief tests. Children participated in group effort conditions that alternated from one condition, where individual effort was transparent and obvious, to one where individual effort remained anonymous. The aim was to investigate if emergent mental state reasoning, after controlling for age, was associated with the well-known phenomenon of reduced effort in group tasks (“social loafing”). Girls had slightly higher ToM scores and social loafing than boys. Hierarchical regression, controlling for age, indicated that understanding of others’ false beliefs uniquely predicted social loafing and interacted weakly with gender status.

Women in Federal Law Enforcement: The Role of Gender Role Orientations and Sexual Orientation in Mentoring

Women have always been under-represented in United States’ law enforcement relative to the population, but women are successful law enforcement officers who bring important skills to the field. Thus, understanding work experiences and the barriers female law enforcement officers face is critical in retaining and promoting women in the field. However, law enforcement is also a masculine, male-dominated occupation causing even greater occupational stress to women through discrimination, exclusion, and harassment (Kakar 2002). The goal of this study was to analyze the relationships among gender role orientations (masculinity and femininity), sexual orientation, and mentoring for female sworn federal law enforcement officers throughout the United States. It was hypothesized that (1) masculine female officers would receive more mentoring, (2) low femininity would enhance masculinity’s effect, (3) sexual minorities would receive less mentoring, negating the beneficial effects of masculinity when the interaction is taken into account, and last, (4) the 3-way interaction between masculinity, femininity, and sexual orientation would uniquely impact mentoring. In the current sample, masculinity was found to positively relate to career mentoring and role modeling whereas sexual orientation was negatively related to career mentoring. The three-way interaction between masculinity, femininity, and sexual orientation also significantly related to career mentoring and role modeling; implications and future directions are discussed.     

Assessment of performance validity in the Stroop Color and Word Test in mild traumatic brain injury patients: A criterion‐groups validation design

The current study assessed performance validity on the Stroop Color and Word Test (Stroop) in mild traumatic brain injury (TBI) using criterion‐groups validation. The sample consisted of 77 patients with a reported history of mild TBI. Data from 42 moderate–severe TBI and 75 non‐head‐injured patients with other clinical diagnoses were also examined. TBI patients were categorized on the basis of Slick, Sherman, and Iverson (1999) criteria for malingered neurocognitive dysfunction (MND). Classification accuracy is reported for three indicators (Word, Color, and Color–Word residual raw scores) from the Stroop across a range of injury severities. With false‐positive rates set at approximately 5%, sensitivity was as high as 29%. The clinical implications of these findings are discussed.     

Intact spatial updating with severely degraded vision

Critical to low-vision navigation are the abilities to recover scale and update a 3-D representation of space. In order to investigate whether these abilities are present under low-vision conditions, we employed the triangulation task of eyes-closed indirect walking to previously viewed targets on the ground. This task requires that the observer continually update the location of the target without any further visual feedback of his/her movement or the target’s location. Normally sighted participants were tested monocularly in a degraded vision condition and a normal vision condition on both indirect and direct walking to previously viewed targets. Surprisingly, we found no difference in walked distances between the degraded and normal vision conditions. Our results provide evidence for intact spatial updating even under severely degraded vision conditions, indicating that participants can recover scale and update a 3-D representation of space under simulated low vision.     

Shifts in attention biases in response to acute pain induction: examination of a model of "conversion" among repressors

Unlike most people, those who are characterized by a repressive coping style report high levels of physical (sensory) pain but low levels of emotional distress (affective pain), which is a discrepancy that may suggest a "conversion" process. In two studies, we tested an attention allocation model, proposing that repressors direct attention away from threatening negative affective information and toward nonthreatening physical pain information during emotionally arousing (painful) situations. In Study 1, 84 participants underwent a cold pressor and then recovered. Repressors reported greater pain during recovery than low- and high-anxious participants, but they reported lower distress than high-anxious participants. Repressors reported significant and large discrepancies between high pain and low distress, whereas these differences were less pronounced for other groups. In Study 2, 77 participants underwent an ischemic pain task while performing a modified dot-probe task with sensory and negative affective pain words as stimuli. Repressors showed increasing biases away from affective pain words and toward sensory pain words as the pain task continued, whereas low- and high-anxious participants did not show these shifts in attention. The results support the notion that conversion among repressors may involve a process by which attention is directed away from emotional distress during noxious stimulation and is focused instead on sensory information from pain.     

Weight ratings of others: The effects of multiple target and rater features

The present study investigated factors that affect the subjective analysis of the weight of other individuals. Three hundred and thirty-three participants viewed figures varying in muscularity, adiposity, gender, and race. For each of the eighteen figures (targets), a 2 (rater gender: male, female) × 3 (rater race/ethnicity: Caucasian, African American, Hispanic) × 3 (target race/ethnicity: Caucasian, African American, Hispanic) repeated measures ANCOVA was conducted (BMI was covaried). Overall, there were few significant effects, however, for some of the figural stimuli, African American raters assigned lower weight ratings than did Caucasian and Hispanic raters. The findings offer support for further investigation of ethnic differences in weight ratings as a potential factor that might inform ethnic differences in overweight and obesity prevalence.     

Recall of 9/11/01 as an Indicator of Cognitive Functioning in the Elderly

The purpose of this study was to assess the relationship between the recall of a highly salient remote event, the terrorist attack in New York City on 9/11/01, and general cognitive functioning in the elderly. A heterogeneous group (n = 93) of persons ≥65 years of age (M = 76.5, SD = 6.4), from both community and hospital settings, were asked to describe as much as they could remember about the events of 9/11/01 in New York City. The number of correct factual details, affective or emotional responses, and incorrect details were recorded. Ten multiple choice questions were then administered to assess recognition of the 9/11 events (M = 9.1 items correct, SD = 1.2). The mini mental state exam (MMSE) was also administered (M = 26.3, SD = 3.4). Participants generated a mean of 4.8 (SD = 3) correct factual details about 9/11, 1.1 affective/emotional responses (SD = 1.1), and 0.22 incorrect recollections (SD = 0.46). Significant correlations (p &;lt; .01) were found between correct details recalled and the MMSE (0.42), education (0.37), and age (?0.31). A significant negative correlation (p &;lt; .01) was found between incorrect details recalled and MMSE scores (?0.38). Female participants generated significantly more affective responses than males (M = 1.3 vs. 0.51; p &;lt; .001) but recall of correct details was equivalent. The recall of 9/11 events, approximately 18 months after the incident, appears related to general mental status, education, and age. Responses to this question may be helpful in assessing the mental status of the elderly. In addition, now that objective memory data has been established, recall of this event by other samples of seniors can be monitored over time to determine the cognitive processes related to the storage and retrieval of this unique and tragic event.     

Gorillas’ use of the escape response in object choice memory tests

The ability to monitor and control one’s own cognitive states, metacognition, is crucial for effective learning and problem solving. Although the literature on animal metacognition has grown considerably during last 15 years, there have been few studies examining whether great apes share such introspective abilities with humans. Here, we tested whether four gorillas could meet two criteria of animal metacognition, the increase in escape responses as a function of task difficulty and the chosen-forced performance advantage. During testing, the subjects participated in a series of object choice memory tests in which a preferable reward (two grapes) was placed under one of two or three blue cups. The apes were required to correctly select the baited blue cup in this primary test. Importantly, the subjects also had an escape response (a yellow cup), where they could obtain a secure but smaller reward (one grape) without taking the memory test. Although the gorillas received a relatively small number of trials and thus experienced little training, three gorillas significantly declined the memory tests more often in difficult trials (e.g., when the location of the preferred reward conflicted with side bias) than in easy trials (e.g., when there was no such conflict). Moreover, even when objective cues were eliminated that corresponded to task difficulty, one of the successful gorillas showed evidence suggestive of improved memory performance with the help of escape response by selectively avoiding trials in which he would be likely to err before the memory test actually proceeded. Together, these findings demonstrate that at least some gorillas may be able to make optimal choices on the basis of their own memory trace strength about the location of the preferred reward.
