A constructive neural-network approach to modeling psychological development

This article reviews a particular computational modeling approach to the study of psychological development – that of constructive neural networks. This approach is applied to a variety of developmental domains and issues, including Piagetian tasks, shift learning, language acquisition, number comparison, habituation of visual attention, concept learning, and theory of mind. Implications of this modeling for theoretical understanding of psychological development are considered.     

Eating regulation and bulimic symptoms: the differential correlates of health-focused and appearance-focused eating regulation

Based on Self-Determination Theory, this study aimed to gain further insight in the pathway from eating regulation to bulimic symptoms by (a) examining diet-specific need frustration as an intervening mechanism, (b) investigating the associations between different types of goals underlying eating regulation and diet-specific need frustration and bulimic symptoms, and (c) considering body dissatisfaction as an antecedent of eating regulation and eating regulation goals. In a sample of 244 female adolescents, SEM analyses showed that (a) the association between eating regulation and bulimic symptoms can be accounted for by need frustration, (b) appearance-focused and health-focused eating regulation are associated differentially with need frustration and bulimic symptoms, and (c) body dissatisfaction is related positively to eating regulation and appearance-focused eating regulation. These findings suggest that the goals underlying one's eating regulation and the concept of need frustration help to understand when and why eating regulation is associated with bulimic symptoms.

Psychological aspects of orthognathic surgery

Abstract

With the dramatic growth in the number of adults undergoing orthodontics to correct malocclusion, and those undergoing surgical orthodontics or orthognathic surgery to correct skeletal discrepancies in the orofacial region, it is important to examine the psychological characteristics of these patients before and after treatment is completed. This paper serves as a general review and summarizes the findings of two major longitudinal studies of patients seeking surgical correction and compares them with people who underwent conventional orthodontics, those who rejected any treatment, and those who sought cosmetic surgery. Both studies revealed that most women seeking surgical orthodontics focused on aesthetic improvement as a motive, whereas men sought to improve their appearance and mastication. Women were also more likely to report problems with the temporomandibular joint as a motive. Men and women scored similarly on a measure of body image, although women reported lower facial image presurgically and higher postsurgically than did men. The greatest gains following surgery were in facial and profile image for both men and women. Orthodontic patients showed less improvement, while those rejecting treatment experienced a decline in body image. Many functional improvements did not occur until 24 months postoperatively; lingering paraesthesia was described by 49% of the sample. Emotional reactions included anxiety preoperatively, and depression postoperatively, especially among patients scoring high on neuroticism and those experiencing other major life events. These studies reveal that people seeking surgical orthodontics are within the normal range of most personality measures and experience greater gains psychologically than do conventional orthodontic patients.     

Self-Reported Psychological Well-Being and Disease-Related Strains among Adults with Diabetes

The study was designed to describe self-reported psychological well-being among adults with Type 1 and Type 2 diabetes and to explore associations of psychological well-being with disease-related strains, such as self-reported long-term complications, frequency of hypoglycaemia and disablement or sick-leave. A sample comprising 534 Norwegian adults with Type 1 and Type 2 diabetes aged 25-70 years participated in the study. Psychological well-being was assessed using three different scales; the WHO (Ten) Well-Being Index, the Short Zung Depression Rating Scale and four items from the anxiety sub-scale of the Hopkins Symptom Checklist. Findings indicate that adults with both types of diabetes reported relatively poor psychological well-being. There was a tendency for younger persons to report the worst psychological well-being. For symptoms of anxiety this tendency was most evident among people with Type 2 diabetes. People being disabled due to diabetes reported relatively markedly impaired psychological well-being, whereas self-reported diabetes-related complications and the number of episodes with hypoglycaemia were weakly associated with psychological well-being. Findings may indicate that healthcare practitioners should pay more attention to the psychological needs of people with diabetes. This applies especially to younger people with Type 2 diabetes.     

Psychological wellbeing and the diathesis-stress hypothesis model: The role of psychological functioning and quality of relations in promoting subjective well-being in a life events study

Negative life events are associated with poor wellbeing and mental health outcomes. Following a diathesis-stress model, we tested whether psychological functioning and quality of interpersonal relationships moderated the effect of life events on subjective wellbeing. This study comprised data from a young and middle-aged adult sample (n = 364) drawn from an Australian university-student population. Results indicated that life events were associated with negative but not positive wellbeing outcomes. Perceived impact of life events was a stronger predictor of wellbeing than was the number of life events. Psychological functioning and quality of interpersonal relationships were associated with both wellbeing dimensions but only quality of interpersonal relationships moderated the effect of life events on wellbeing. In conclusion, perceived impact of life events was more strongly related to wellbeing than number of life events. Interpersonal relationships moderate the effect of life events with those reporting higher levels of quality of interpersonal relationships reporting less decrement in negative affect following stressful life events.     

Closure of autobiographical memories: The effects of written recounting from first- or third-person visual perspective

Autobiographical memories are recalled with varying degrees of psychological closure. Closure is a subjective assessment of how far a remembered experience feels resolved, and it has been suggested that one predictor of closure is the amount of emotional detail in the memory. Study 1 examined which aspect of emotional detail is important for closure, and showed that open and closed negative memories were distinguished by ratings of emotion evoked during recall, not by remembered emotion from the time of the event. The recall of open memories was accompanied by more intense, more negative, and less positive emotion than the recall of closed memories. Biased retelling of memories has been shown to influence closure and on the basis of evidence that third-person recall serves a distancing function, Study 2 examined whether instructions to repeatedly recount an open memory from a third-person perspective would increase closure compared with a single or repeated recounting from a first-person perspective. While repeated third-person recounting had the greatest influence on closure, there were also increases in the first-person recounting groups. The results suggest that closure can be increased by reporting memories in written narrative form, particularly if repeatedly expressed from the third-person perspective.
