Age differences in reasons for exercising

We tested the hypothesis that there are age-related differences in reasons for exercising. Adults (n=461), ranging in age from 18 to 86, were asked to indicate if they had considered different types of consequences in their exercise decisions, and how important they thought those consequences were to consider. A three-factor consequence measure examined individuals’ consideration and importance evaluations of various categories of exercise consequences. Results provided mixed support for the hypotheses that younger individuals exhibit greater concern for interpersonal attraction outcomes, while older individuals exhibit greater concern for health outcomes. These results have implications for designing educational and motivational training programs.     

Attachment and Autism: Parental Attachment Representations and Relational Behaviors in the Parent-Child Dyad

While attachment research has demonstrated that parents’ internal working models of attachment relationships tend to be transmitted to their children, affecting children’s developmental trajectories, this study specifically examines associations between adult attachment status and observable parent, child, and dyadic behaviors among children with autism and associated neurodevelopmental disorders of relating and communicating. The Adult Attachment Interview (AAI) was employed to derive parental working models of attachment relationships. The Functional Emotional Assessment Scale (FEAS) was used to determine the quality of relational and functional behaviors in parents and their children. The sample included parents and their 4- to 16-year-old children with autism and associated neurodevelopmental disorders. Hypothesized relationships between AAI classifications and FEAS scores were supported. Significant correlations were found between AAI classification and FEAS scores, indicating that children with autism spectrum disorders whose parents demonstrated secure attachment representations were better able to initiate and respond in two-way pre-symbolic gestural communication; organize two-way social problem-solving communication; and engage in imaginative thinking, symbolic play, and verbal communication. These findings lend support to the relevance of the parent’s state of mind pertaining to attachment status to child and parent relational behavior in cases wherein the child has been diagnosed with autism or an associated neurodevelopmental disorder of relating and communicating. A model emerges from these findings of conceptualizing relationships between parental internal models of attachment relationships and parent-child relational and functional levels that may aid in differentiating interventions.     

Better mood and better performance. Learning rule-described categories is enhanced by positive mood

Theories of mood and its effect on cognitive processing suggest that positive mood may allow for increased cognitive flexibility. This increased flexibility is associated with the prefrontal cortex and the anterior cingulate cortex, both of which play crucial roles in hypothesis testing and rule selection. Thus, cognitive tasks that rely on behaviors such as hypothesis testing and rule selection may benefit from positive mood, whereas tasks that do not rely on such behaviors should not be affected by positive mood. We explored this idea within a category-learning framework. Positive, neutral, and negative moods were induced in our subjects, and they learned either a rule-described or a non-rule-described category set. Subjects in the positive-mood condition performed better than subjects in the neutral- or negative-mood conditions in classifying stimuli from rule-described categories. Positive mood also affected the strategy of subjects who classified stimuli from non-rule-described categories.

Fetal neurobehavioral development: a tale of two cities

Longitudinal neurobehavioral development was examined in 237 fetuses of low-risk pregnancies from 2 distinct populations--Baltimore, Maryland, and Lima. Peru--at 20, 24, 28, 32, 36, and 38 weeks gestation. Data were based on digitized Doppler-based fetal heart rate (FHR) and fetal movement (FM). In both groups. FHR declined while variability, episodic accelerations, and FM-FHR coupling increased, with discontinuities evident between 28 and 32 weeks gestation. Fetuses in Lima had higher FHR and lower variability, accelerations, and FM-FHR coupling. Declines in trajectories were typically observed 1 month sooner in Lima, which magnified these disparities. Motor activity differences were less consistent. No sex differences in fetal neurobehaviors were detected. It is concluded that population factors can influence the developmental niche of the fetus.     

Validity of Two Language Versions of the Auckland Individualism and Collectivism Scale with Filipino-English Bilinguals

The Auckland Individualism and Collectivism Scale (AICS) was translated into Filipino; and the factorial structure of the Filipino and English versions were validated with two samples of Filipino-English bilinguals. Most of the fit indexes in the confirmatory factor analysis indicated that the data from the Filipino translation and the original English version both fit the hypothesized internal structure of the scale. The results provide further support for the structural aspects of the AICS’ construct validity; however, some minor issues were noted at the level of individual items and subscales.     

Co-morbid pain conditions and feelings of invalidation and isolation among women with vulvodynia

Many women with vulvodynia also suffer from other chronic co-morbid pain conditions. Alone, these pain conditions are associated with feeling invalidated by others and feeling socially isolated. It is unclear, however, how the presence of additional pain co-morbidities are associated with the psychosocial wellbeing of women with vulvodynia. We used data from a survey administered by the National Vulvodynia Association. Women reported clinician-diagnosed vulvodynia, presence of co-morbid pain, and how often they felt that they felt no one believed their pain existed (invalidated) and isolated. Analyses determined prevalence of feeling invalidated or isolated, and the difference in prevalence when co-morbidities existed. Forty-five percent of these 1847 women with vulvodynia reported having at least one of the following five chronic pain conditions, chronic fatigue syndrome, endometriosis, fibromyalgia, interstitial cystitis, or irritable bowel syndrome. Adjusted baseline prevalence among all women of feeling invalidated was 9% and of feeling isolated was 14%. Having a co-morbid condition with vulvodynia, as well as having an increasing number of co-morbid conditions with vulvodynia, was significantly associated with the presence of feeling both invalidated and isolated. Chronic fatigue syndrome was the co-morbidity most strongly associated with feelings invalidation and isolation. One or more co-morbid pain conditions in addition to vulvodynia were significantly associated with psychosocial wellbeing. However, the temporality of the association could not be elucidated and therefore we cannot conclude that these pain conditions cause poor psychosocial wellbeing. Despite this, future studies should explore the utility of promoting validation of women's pain conditions and reducing social isolation for women with chronic pain.
