Implications of Psychosocial Factors for Diabetes Outcomes among Children with Type 1 Diabetes: A Review

We adopt a risk and resistance framework to review the literature on the psychosocial factors that influence diabetes outcomes—specifically self‐care behavior (blood glucose monitoring, diet, exercise, insulin administration) and glycemic control. We examine both personal and social/environmental risk and resistance factors. We conclude by suggesting conceptual and methodological directions for future research. Conceptually, we suggest that researchers examine the synergy among variables that cut across domains, mechanisms linking psychosocial factors to diabetes outcomes, and the impact of goals on health. Methodologically, we suggest that researchers examine age, gender, and race as moderator variables; utilize momentary data collection technology; and employ more sophisticated longitudinal analyses.     

Attention and social functioning in children with malformations of cortical development and stroke

Attention and social functioning and their interrelationships have not been routinely examined in children with early brain insult (EBI). This study aimed to describe attention and social functioning in children with two types of EBI: malformations of cortical development (MCD) and stroke. Children diagnosed with MCD (n?=?14, 6 males) or stroke (n?=?14, 8 males) aged 8 to 14 years (M?=?12 years 11 months) completed neuropsychological assessments to examine attention processes. Primary caregivers completed a questionnaire to assess executive components of children's attention and teachers completed a questionnaire to measure children's social functioning. Brain scans (MRI or CT) were coded by a pediatric neuroradiologist. Higher rates of impairments in attention and social function were found in children with EBI compared with normative expectations. Children with MCD experienced more global and clinically significant levels of impairment than children with stroke; though impairments were present in both groups. A strong association between executive components of attention and social function was observed. In addition, complex attention processes were associated with social function. The findings emphasize the reciprocity between attention, behavior and social outcomes, and the vulnerability of social function following EBI.     

Multiple repetition priming of faces: Massed and spaced presentations

Previously viewing a face typically leads to a decrease in the amount of time taken to later identify it (“repetition priming”). Five repetition priming experiments are reported, which investigate whether multiple presentations of a face increase the amount of repetition priming. The results demonstrate similar amounts of priming from massed multiple presentations of the same face or a series of different images (freeze frames selected from a moving clip and presented in sequence), compared with a single unchanging presentation (Experiments 1 and 2). This is true even when different images are presented at prime and test (Experiment 3). However when multiple presentations were presented in a spaced fashion, with one or more intervening items between each repeat, there was significantly more priming in the multiple than single presentation condition (Experiment 4). This was true even when the face was named only once in both the multiple and single spaced conditions (Experiment 5). The results are discussed in relation to face motion.     

Self-perception and motivational characteristics of tennis participants: The influence of age and skill

Abstract

An integrated approach to the study of psychosocial factors related to participation behavior was adopted by incorporating developmental, skill acquisition, and psychosocial variables. Specifically, the relationship of age and skill with self-perceptions and motivational characteristics of tennis participants was examined. Males and females (N = 240) ranged in age from 10 to 67 years. Professional tennis coaches verified the skill rating of each player using the National Tennis Rating Program introduced by the United States Tennis Association. Individuals completed self-report scales measuring perceived tennis competence, tennis salience, global self-worth, challenge motivational orientation, task and ego orientations, and competitive trait anxiety. Canonical correlation analyses revealed that age and skill were significantly related to psychosocial variables for both males and females. These findings suggest that an integrated research approach can extend our understanding of social-psychological variables in the physical activity setting.     

Floral guidance of learning a preference for symmetry by bumblebees

This study examines the mechanism underlying one way in which bumblebees are known to develop a preference for symmetric patterns: through prior non-differential reinforcement on simple patterns (black discs and white discs). In three experiments, bees were given a choice among symmetric and asymmetric black-and-white non-rewarding patterns presented at the ends of corridors in a radial maze. Experimental groups had prior rewarded non-discrimination training on white patterns and black patterns, while control groups had no pre-test experience outside the colony. No preference for symmetry was obtained for any of the control groups. Prior training with circular patterns highlighting a horizontal axis of symmetry led to a specific subsequent preference for horizontal over vertical symmetry, while training with a vertical axis abolished this effect. Circles highlighting both axes created a general avoidance of asymmetry in favour of symmetric patterns with vertical, horizontal or both axes of symmetry. Training with plain circles, but not with deformed circles, led to a preference for symmetry: there was no evidence that the preference emerged just by virtue of having attention drawn away from irrelevant pattern differences. Our results point to a preference for symmetry developing gradually through first learning to extract an axis of symmetry from simple patterns and subsequently recognizing that axis in new patterns. They highlight the importance of continued learning through non-differential reinforcement by skilled foragers. Floral guides can function not only to guide pollinators to the source of reward but also to highlight an axis of symmetry for use in subsequent floral encounters.     

Stress and depression of facing death: Investigation of psychological symptoms in patients with mesothelioma

Cancer often results in psychological impairment, and lung cancer has been associated with greater morbidity and higher levels of psychological distress than any other form. Chronic exposure to asbestos is a significant risk factor for development of lung cancer, called mesothelioma. Few have studied the psychological consequences of chronic asbestos exposure and mesothelioma. This study investigated stress and depression symptoms in 49 men (M = 51.1 years, SD = 6.0) diagnosed with mesothelioma. Participants completed traumatic stress, depression and general psychological health questionnaires. All participants reported significant levels of traumatic stress symptoms, which was associated with increased symptoms of depression, anxiety, somatic complaints and social dysfunction. The results provide important suggestions for clinicians treating such terminally ill patients.     

Individual differences in online spoken word recognition: Implications for SLI

Thirty years of research has uncovered the broad principles that characterize spoken word processing across listeners. However, there have been few systematic investigations of individual differences. Such an investigation could help refine models of word recognition by indicating which processing parameters are likely to vary, and could also have important implications for work on language impairment. The present study begins to fill this gap by relating individual differences in overall language ability to variation in online word recognition processes. Using the visual world paradigm, we evaluated online spoken word recognition in adolescents who varied in both basic language abilities and non-verbal cognitive abilities. Eye movements to target, cohort and rhyme objects were monitored during spoken word recognition, as an index of lexical activation. Adolescents with poor language skills showed fewer looks to the target and more fixations to the cohort and rhyme competitors. These results were compared to a number of variants of the TRACE model (McClelland & Elman, 1986) that were constructed to test a range of theoretical approaches to language impairment: impairments at sensory and phonological levels; vocabulary size, and generalized slowing. None of the existing approaches were strongly supported, and variation in lexical decay offered the best fit. Thus, basic word recognition processes like lexical decay may offer a new way to characterize processing differences in language impairment.
