Detection of grouped and ungrouped parts in visual patterns by tufted capuchin monkeys (Cebus apella) and humans (Homo sapiens)

The authors investigated perceptual grouping in capuchin monkeys (Cebus apella) and humans (Homo sapiens). In Experiment 1, 6 monkeys received a visual pattern as the sample and had to identify the comparison stimulus featuring some of its parts. Performance was better for ungrouped parts than for grouped parts. In Experiment 2, the sample featured the parts, and the comparison stimuli, the complex figures: The advantage for ungrouped elements disappeared. In Experiment 3, in which new stimuli were introduced, the results of the previous experiments were replicated. In Experiment 4, 128 humans were presented with the same tasks and stimuli used with monkeys. Their accuracy was higher for grouped parts. Results suggest that human and nonhuman primates use different modes of analyzing multicomponent patterns.     

Reorganization in coping behavior at 1 1/2 years: dynamic systems and normative change

By the age of 1 year toddlers demonstrate distinct coping habits for dealing with frustration. However, these habits may be open to change and reorganization at subsequent developmental junctures. We investigated change in coping habits at 18-20 months, a normative age for major advances in social cognition, focusing on the dynamic systems principles of fluctuation and novelty at transitions. Specifically, we asked whether month-to-month fluctuation, novel behavioral habits and real-time variability increased at the age of a normative transition, despite individual differences in the content of behavior. Infants were given frustrating toys while their mothers sat nearby without helping, on monthly visits at 14-25 months (before, during and after the hypothesized transition). State space grids representing patterns of behavioral durations were constructed for each episode and compared over age. As predicted, month-to-month fluctuation in grid patterns increased temporarily between 17 and 20 months, partly independently of a concurrent peak in distress, and new behavioral habits replaced old ones at the same age. Coping habits changed differently for high-and low-distressed toddlers. However, changes in real-time variability did not generally meet our expectations.     

Relating emotional abilities to social functioning: a comparison of self-report and performance measures of emotional intelligence

Three studies used J. D. Mayer and P. Salovey's (1997) theory of emotional intelligence (EI) as a framework to examine the role of emotional abilities (assessed with both self-report and performance measures) in social functioning. Self-ratings were assessed in ways that mapped onto the Mayer-Salovey-Caruso Emotional Intelligence Test (MSCEIT), a validated performance measure of EI. In Study 1, self-ratings and MSCEIT scores were not strongly correlated. In Study 2, men's MSCEIT scores, but not self-ratings, correlated with perceived social competence after personality measures were held constant. In Study 3, only the MSCEIT predicted real-time social competence, again, just for men. Implications for analyzing how emotional abilities contribute to social behavior are discussed, as is the importance of incorporating gender into theoretical frameworks and study designs.     

Exhaustion is differentiable from depression and anxiety: evidence provided by the SF-36 vitality scale

Stress-related exhaustion is an increasingly focused phenomenon, although scientifically not yet fully conceptualised. This is perhaps partly due to the fact that the distinction between exhaustion and other already established concepts, such as depression, is not clear. This study explores whether exhaustion can be differentiated from depression and anxiety, by means of introducing the SF-36 vitality scale as a strategy for the measurement of exhaustion. The Malm? Shoulder and Neck Study cohort, in this study including 12,607 middle-aged men and women, was utilized. Depression and anxiety were assessed by the general health questionnaire (GHQ). Factor analysis was performed in order to potentially discriminate between the included measures. Factor analysis showed that all four exhaustion items of the (inverted) SF-36 vitality scale loaded on a single factor, separate from the GHQ depression and anxiety factors. These results support the notion that exhaustion can be distinguished from depression and anxiety, providing an empirical foundation for defining exhaustion as a unique concept. Furthermore, since SF-36 has been widely used in clinical and epidemiological studies, the benefits of using the SF-36 vitality scale in the assessment of exhaustion could be substantial.     

Risk Reduction Behaviors and Provider Communication Following Genetic Counseling and BRCA1 Mutation Testing in an African American Kindred

Little is known about the impact of cancer genetic counseling and testing on health behaviors in racial and ethnic subgroups. This prospective observational study examined use of risk reduction strategies following BRCA1 counseling and testing. Participants were female members of an African American kindred who received genetic education, counseling and testing (n = 40) and completed a 1-year follow-up interview. Mutation carriers were more likely to opt for breast (100%, 7/7) and ovarian (25%; 1 of 4) cancer surveillance than prophylactic surgery. Following genetic counseling, 71% (5/7) of the BRCA1 carriers who opted for surveillance reported having a mammogram within the year following receipt of their genetic test results. Ovarian cancer screening among mutation carriers increased from 0% at baseline to 25% (one of four) at 1 year. Compared to noncarriers (23%, 7/30), carriers (70%, 7/10) were more likely to discuss their BRCA1 test results with their primary health care providers. Surveillance for breast cancer was preferred to prophylactic surgery and chemoprevention as a way to reduce risk for these cancers. Our data indicate that patient-provider communication about BRCA1 test results is suboptimal.     

Is severe obesity a form of addiction? Rationale, clinical approach, and controlled clinical trial.

For many, obesity is just a problem of energy input and expenditure: more energy input than expenditure. However, the clinical practice and epidemiological data clearly show that weight control is more complex than expected by this simple equation. This is particularly true in morbid obesity, a form of severe obesity in which a person's Body Mass Index (BMI, kg/m(2)) is over 40. If we compare the definitions and diagnostic criteria for "dependence" and "addiction" with the situation of many severe obese subjects, it is apparent that they match very well. Further, different neurological studies confirm this similarity: both addiction and obesity patients have a deficiency of dopamine receptors. Nevertheless, when we compare many of the actual obesity treatments with the ones used in the area of addictions it is possible to find relevant differences: obesity treatments neither consider different levels of type and intensity of care, nor a multidimensional approach. To overcome these limitations, in this paper we propose a bio-psychosocial approach in which the genetic influence (lack of dopamine receptors) is matched by psychosocial issues (pressure for thinness and diet as main body image dissatisfaction treatment). Further, the paper outlines how this approach may influence the treatment options, by focusing both on the lessons coming from actual addiction treatment and the opportunities offered by virtual reality. Finally, the paper presents and discusses the outcome of a controlled trial, based on the proposed approach, including a 6-month follow-up (211 morbid obese females with a BMI of >40 and a documented history of failures.     

The Impact of Parenting Experience on Gender Stereotyped Toy Play of Children

The purpose of this study was to examine gender role socialization as a function of parenting experience in an actual toy play situation and as a function of adults' perceptions of typically gender-stereotyped children's toys. Each of 48 children (24 boys and 24 girls) played with 3 adults: either his or her own mother or father, a matched mother or father of another child, and a matched man or woman who was not a parent. The amount of time children and adults played with gender-specific toys, adults' categorization of toys into gender categories, and adults' desirability ratings of gender-specific toys were examined. The gender-sorting task revealed that adults did not agree with traditional expert categorizations of some of the toys, which suggests a shift in the perceived function of some traditionally stereotyped toys. Regardless of how parents sorted toys into categories, when playing with boys, most time was spent with masculine toys. With girls, however, there was greater flexibility in the categories of toys with which they played. Parenting experience influenced the perceived desirability of toys; parents found toys more desirable than nonparents but these differences did not affect the actual play session with children. These results suggest a change in perceptions of traditionally stereotyped toys and differences as a function of gender in what is appropriate gender-typing behavior.     

Multiple systems for spatial learning: dead reckoning and beacon homing in rats

Rats homed with food in a large lighted arena. Without visual cues, they used dead reckoning. When a beacon indicated the home, rats could also use the beacon. Homing did not differ in 2 groups of rats, 1 provided with the beacon and 1 without it; tests without the beacon gave no evidence that beacon learning overshadowed dead reckoning (Experiment 1). When the beacon was at the home for 1 group and in random locations for another, there was again no evidence of cue competition (Experiment 2). Dead reckoning experience did not block acquisition of beacon homing (Experiment 3). Beacon learning and dead reckoning do not compete for predictive value but acquire information in parallel and are used hierarchically.     

Development and Initial Validation of the Child Routines Inventory

The importance of establishing predictable routines during childhood consistently has been emphasized in the popular parenting literature, despite a paucity of empirical evidence. The lack of research may be partially due to a lack of suitable instruments designed to measure children's routines. This study describes development and preliminary psychometric data in support of the Child Routines Inventory (CRI), an empirically derived, content-valid, parent-report measure of commonly occurring routines in school-aged children. Principal components analysis yielded a four-factor structure (composed of 36 items), accounting for 44.2% of the total variance. The CRI was found to have excellent internal consistency ( = .90), good test-retest reliability (r = .86), and preliminary evidence of construct validity, demonstrating a moderate relationship with measures of child behavior problems and family routines. These results suggest the CRI to be a promising new measure of child routines that would benefit from further validation studies.
