Working Memory and Motor Activity: A Comparison Across Attention-Deficit/Hyperactivity Disorder,Generalized Anxiety Disorder,and Healthy Control Groups

Converging findings from recent research suggest a functional relationship between attention-deficit/hyperactivity disorder (ADHD)-related hyperactivity and demands on working memory (WM) in both children and adults. Excessive motor activity such as restlessness and fidgeting are not pathognomonic symptoms of ADHD, however, and are often associated with other diagnoses such as generalized anxiety disorder (GAD). Further, previous research indicates that anticipatory processing associated with anxiety can directly interfere with storage and rehearsal processes of WM. The topographical similarity of excessive motor activity seen in both ADHD and anxiety disorders, as well as similar WM deficits, may indicate a common relationship between WM deficits and increased motor activity. The relationship between objectively measured motor activity (actigraphy) and PH and visuospatial WM demands in adults with ADHD (n = 21), adults with GAD (n = 21), and healthy control adults (n = 20) was examined. Although all groups exhibited significant increases in activity from control to WM conditions, the ADHD group exhibited a disproportionate increase in activity, while activity exhibited by the GAD and healthy control groups was not different. Findings indicate that ADHD-related hyperactivity is uniquely related to WM demands, and appear to suggest that adults with GAD are no more active relative to healthy control adults during a cognitively demanding laboratory task.     

The psychometric properties of the Quality of Life Inventory in an Australian community sample

The Quality of Life Inventory (QOLI, Frisch) is an importance‐weighted measure of life satisfaction that has been found to possess adequate psychometric properties in US and clinically‐based samples. The current study aimed to investigate the normative distribution, factor structure and key psychometric properties of the QOLI in an Australian general community sample. Results indicated that the Australian sample (n = 259) reported slightly better quality of life than the US‐based standardisation sample. Confirmatory factor analyses showed that a three‐factor model provided the best fit for the data. Psychometric properties were all generally found to be adequate and close to Frisch's reported levels. In conclusion, this study indicated that the QOLI may be used in the Australian context with confidence. Future research could examine the clinical utility of the three‐factor model.     

Type A Personality Characteristics and the Effect on Individual and Team Academic Performance

Type A personality has been conceptualized in part as high need for achievement combined with aggression, hostility, and self-esteem issues. In teams of undergraduate business students, high levels of Type A personality significantly correlated with high levels of depression and high levels of social monitoring; and negatively correlated with social desirability, communality, and individual performance across time. In team settings, the more Type A's were balanced in a team with low Type A's, the more there was team commitment and the more team synergy behaviors; while if teams had a greater number of Type A's, there was more individualistic behavior, and team project scores were lower.     

A new argument for the phenomenal approach to personal persistence

Philosophical Studies - When it comes to personal identity, two approaches have long ruled the roost. The first is the psychological approach, which has it that our persistence through time...     

Recognition,Attachment, and the Social Bases of Self-Worth

Recognition theorists have often sought to justify calls for the recognition of identities or cultures on grounds that a culturally egalitarian societal environment is a crucial social basis of a sense of self-worth. In doing so they have often drawn on noncognitivist social-psychological theorizing. This paper argues that this theorizing does not support the recognition theorist's position. It is argued that attachment theory together with recent empirical evidence support a more attachment- focused and Rawlsian vision of self-worth's social bases according to which secure parent-child attachment, associational ties, equal basic rights and liberties, and economic and educational opportunities are what really matter.     

Levinas's Philosophy of Perception

Levinas is usually discussed as a philosopher wrestling with the nature of our experience of others, ethical obligation, and the divine. Unlike other phenomenologists, such as Husserl and Heidegger, he is not often mentioned in discussions about issues in philosophy of mind. His work in that area, especially on perception, is underappreciated. He gives an account of the nature of perceptual experience that is remarkable both in how it departs from that of others in the phenomenological tradition and for how it fits in among presently available views about the nature of perceptual experience, namely, as a form of naïve realism.     

Psychopathology Following Interpersonal Violence: A Comparison of Risk Factors in Older and Younger Adults

A randomly selected sample of 549 women age 55 years and older and 2,669 women age 18–34 years was interviewed via telephone to determine prevalences of physical and sexual assault, posttraumatic stress disorder (PTSD) symptomatology, and depression. Prevalences of sexual and physical assaults were lower in older compared to younger women. In addition, given a trauma, prevalences and proportionate risk of posttraumatic psychopathology and depression were also lower for older, relative to younger women. Specifically, multivariate analyses revealed that sexual assault predicted only PTSD avoidance in older adults, but all forms of PTSD symptomatology and depression in younger adult women. Similarly, physical assault predicted only PTSD re-experiencing symptoms in older women, but all forms of PTSD symptoms and depression in younger women. Self-reported health status was not associated with any increased risk of psychopathology, and low income predicted increased avoidance and depression only in younger women.
