The Effects of Prenatal Alcohol Exposure on Behavior: Rodent and Primate Studies

The use of alcohol by women during pregnancy is a continuing problem. In this review the behavioral effects of prenatal alcohol from animal models are described and related to studies of children and adults with FASD. Studies with monkeys and rodents show that prenatal alcohol exposure adversely affects neonatal orienting, attention and motor maturity, as well as activity level, executive function, response inhibition, and sensory processing later in life. The primate moderate dose behavioral findings fill an important gap between human correlational data and rodent mechanistic research. These animal findings are directly translatable to human findings. Moreover, primate studies that manipulated prenatal alcohol exposure and prenatal stress independently show that prenatal stress exacerbates prenatal alcohol-induced behavioral impairments, underscoring the need to consider stress-induced effects in fetal alcohol research. Studies in rodents and primates show long-term effects of prenatal and developmental alcohol exposure on dopamine system functioning, which could underpin the behavioral effects.     

Assessing the predictive validity of cultural intelligence over time

The study examines four core components of cultural intelligence (CQ) - Behavioral, Motivational, Cognitive and Meta-cognitive - as predictors of cross-cultural adaptation problems in a longitudinal study of international students in New Zealand and tests the hypothesis that Motivational CQ predicts better psychological and sociocultural outcomes over time. One hundred and four students completed measures of CQ during a pre-term orientation program and assessments of adaptation problems approximately three months later. In line with the hypothesis, bi-variate correlations indicated that Motivational CQ was related to fewer psychological symptoms (r = −.30, p < .01) and sociocultural adaptation problems (r = −.27, p < .01). However, hierarchical regression analysis, controlling for age, gender, length of residence abroad and region of origin, revealed that while Motivational CQ was a significant (negative) predictor (ß = −.36, p < .01) of psychological symptoms, the overall amount of variance explained (14.6%) in the model was not significant. In contrast, region of origin (ß = .37, p < .01) was the only significant predictor of sociocultural adaptation problems with international students from Western countries reporting fewer difficulties than those from other regions. The results are discussed in relation to contemporary theories of motivation along with recommendations for future research.     

Friends with benefits: on the positive consequences of pet ownership

Social support is critical for psychological and physical well-being, reflecting the centrality of belongingness in our lives. Human interactions often provide people with considerable social support, but can pets also fulfill one's social needs? Although there is correlational evidence that pets may help individuals facing significant life stressors, little is known about the well-being benefits of pets for everyday people. Study 1 found in a community sample that pet owners fared better on several well-being (e.g., greater self-esteem, more exercise) and individual-difference (e.g., greater conscientiousness, less fearful attachment) measures. Study 2 assessed a different community sample and found that owners enjoyed better well-being when their pets fulfilled social needs better, and the support that pets provided complemented rather than competed with human sources. Finally, Study 3 brought pet owners into the laboratory and experimentally demonstrated the ability of pets to stave off negativity caused by social rejection. In summary, pets can serve as important sources of social support, providing many positive psychological and physical benefits for their owners.     

Liking and response latency in teammate identification: processing delays below conscious awareness?

Success in fast-ball sports relies on many factors which interact at both movement and cognitive levels. Players must recognize their teammates and decide whether to pass the ball to create or take advantage of scoring affordances. Previous research has shown athletes can identify teammates from brief visual displays during fast-ball sports and this is related to the amount of time individuals train together. However, it is likely other factors also affect recognition and, consequently, decision making related to ball passing. The present study extended the Teammate Identification (TM-ID) paradigm to examine magnitude of liking of one's teammates in relation to response time components of TM-ID. An increase in movement time was found for identifying a swimmer who was the observer's "least liked" teammate, which suggests that processes below conscious awareness may influence the time taken for sport actions directed toward specific teammates, such as ball passing.     

Exploring outcomes through narrative: the long-term impacts of Better Beginnings, Better Futures on the turning point stories of youth at ages 18-19

This study examined the long-term effects of the Better Beginnings, Better Futures project, a community-based early childhood development program, on 18–19 year-old youths’ narratives about turning points in their lives. The sample consisted of youth who participated in Better Beginnings from ages 4–8 (n = 62) and youth from a comparison community who did not participate in Better Beginnings (n = 34). Controlling for covariates, significant differences favoring youth from the Better Beginnings sites were found on several dimensions of the turning point stories: ending resolution, personal growth, meaning-making, coherence, and affect transformation. Effect sizes ranged from .45 to .76 for these outcome dimensions, indicating moderate to large effects. Also, turning point story dimensions were found to be significantly correlated with two standardized measures of well-being: youths’ self-esteem and community involvement. Youths’ self-esteem was directly related to story ending resolution, personal growth, and meaning making, and youths’ community involvement was directly related to story specificity, meaning making, and coherence. Family functioning was also examined in relation to these narrative dimensions but was not found to be significantly related to them. The findings suggest the utility of a narrative approach for the evaluation of the long-term outcomes of early childhood development programs.     

Cosmetic surgery in inpatients with eating disorders: attitudes and experience

Body image disturbance is frequent among individuals undergoing cosmetic surgery and core to the pathology of eating disorders (ED); however, there is little research examining cosmetic surgery in ED. This study examined body image related measures, ED behaviors, and depression as predictors of attitudes toward cosmetic surgery in 129 women with ED. Patients who had undergone surgery (n = 16, 12%) were compared to those who had not. Having a purging diagnosis, linking success to appearance, and making physical appearance comparisons were predictive of more favorable cosmetic surgery attitudes. All of those who had undergone surgery had purging diagnoses and, on average, were older, had higher BMIs, and were more likely to make physical appearance comparisons and know someone who had undergone surgery. In ED, acceptance and pursuit of cosmetic surgery appears to be related to social group influences more than weight and shape disturbance, media influences, or mood.     

Bias in the Reporting of Family History: Implications for Clinical Care

Family history of cancer is critical for identifying and managing patients at risk for cancer. However, the quality of family history data is dependent on the accuracy of patient self reporting. Therefore, the validity of family history reporting is crucial to the quality of clinical care. A retrospective review of family history data collected at a community hospital between 2005 and 2009 was performed in 43,257 women presenting for screening mammography. Reported numbers of breast, colon, prostate, lung, and ovarian cancer were compared in maternal relatives vs. paternal relatives and in first vs. second degree relatives. Significant reporting differences were found between maternal and paternal family history of cancer, in addition to degree of relative. The number of paternal family histories of cancer was significantly lower than that of maternal family histories of cancer. Similarly, the percentage of grandparents' family histories of cancer was significantly lower than the percentage of parents' family histories of cancer. This trend was found in all cancers except prostate cancer. Self-reported family history in the community setting is often influenced by both bloodline of the cancer history and the degree of relative affected. This is evident by the underreporting of paternal family histories of cancer, and also, though to a lesser extent, by degree. These discrepancies in reporting family history of cancer imply we need to take more care in collecting accurate family histories and also in the clinical management of individuals in relation to hereditary risk.     

Development of abbreviated nine-item forms of the Raven's standard progressive matrices test

The Raven's standard progressive matrices (RSPM) is a 60-item test for measuring abstract reasoning, considered a nonverbal estimate of fluid intelligence, and often included in clinical assessment batteries and research on patients with cognitive deficits. The goal was to develop and apply a predictive model approach to reduce the number of items necessary to yield a score equivalent to that derived from the full scale. The approach is based on a Poisson predictive model. A parsimonious subset of items that accurately predicts the total score was sought, as was a second nonoverlapping alternate form for repeated administrations. A split sample was used for model fitting and validation, with cross-validation to verify results. Using nine RSPM items as predictors, correlations of .9836 and .9782 were achieved for the reduced forms and .9063 and .8978 for the validation data. Thus, a 9-item subset of RSPM predicts the total score for the 60-item scale with good accuracy. A comparison of psychometric properties between 9-item forms, a published 30-item form, and the 60-item set is presented. The two 9-item forms provide a 75% administration time savings compared with the 30-item form, while achieving similar item- and test-level characteristics and equal correlations to 60-item based scores.     

Action production influences 12-month-old infants' attention to others' actions

Recent work implicates a link between action control systems and action understanding. In this study, we investigated the role of the motor system in the development of visual anticipation of others' actions. Twelve-month-olds engaged in behavioral and observation tasks. Containment activity, infants' spontaneous engagement in producing containment actions; and gaze latency, how quickly they shifted gaze to the goal object of another's containment actions, were measured. Findings revealed a positive relationship: infants who received the behavior task first evidenced a strong correlation between their own actions and their subsequent gaze latency of another's actions. Learning over the course of trials was not evident. These findings demonstrate a direct influence of the motor system on online visual attention to others' actions early in development.
