Rotated Drawing: The Range of Performance and Anatomical Correlates in a Series of 16 Patients

Recently there has been interest in an unusual neuropsychological disorder in which the patient copies a complex drawing in a position which is grossly rotated relative to the original. This disorder is of interest partly because of its relationship to current theories of the process of object recognition, but the range of performances typically seen, as well as its anatomical correlates, remain obscure. We report 16 cases who produced grossly rotated drawings of the Rey and Taylor Complex Figures. These patients were drawn from an unselected series of 240 cases, with a wide variety of lesion types and sites. The performances of the 16 patients displayed striking similarities. We describe the formal features of these drawings and plot their anatomical correlates.     

Acceptability of Psychotherapy, Pharmacotherapy, and Self-Directed Therapies in Australians Living with Chronic Hepatitis C

Despite the prevalence of psychiatric co-morbidity in chronic hepatitis C (CHC), treatment is under-researched. Patient preferences are likely to affect treatment uptake, adherence, and success. Thus, the acceptability of psychological supports was explored. A postal survey of Australian CHC outpatients of the Royal Adelaide Hospital and online survey of Australians living with CHC was conducted, assessing demographic and disease-related variables, psychosocial characteristics, past experience with psychological support, and psychological support acceptability. The final sample of 156 patients (58 % male) had significantly worse depression, anxiety, stress, and social support than norms. The most acceptable support type was individual psychotherapy (83 %), followed by bibliotherapy (61 %), pharmacotherapy (56 %), online therapy (45 %), and group psychotherapy (37 %). The most prominent predictor of support acceptability was satisfaction with past use. While individual psychotherapy acceptability was encouragingly high, potentially less costly modalities including group psychotherapy or online therapy may be hampered by low acceptability, the reasons for which need to be further explored.     

Presence within a mixed reality environment.

Mixed reality environments represent a new approach to creating technology-mediated experiences. However, there is a lack of empirical research investigating users' actual experience. The aim of the current exploratory, non-experimental study was to establish levels of and identify factors associated with presence, within the framework of Schubert et al.'s model of presence. Using questionnaire and interview methods, the experience of the final performance of the Desert Rain mixed reality environment was investigated. Levels of general and spatial presence were relatively high, but levels of involvement and realness were not. Overall, intrinsic motivation, confidence and intention to re-visit Desert Rain were high. However, age was negatively associated with both spatial presence and confidence to play. Furthermore, various problems in navigating the environment were identified. Results are discussed in terms of Schubert's model and other theoretical perspectives. Implications for system design are presented.     

Real versus facsimile reinforcers on the Iowa Gambling Task

The Iowa Gambling Task (([Bechara et al., 1994]) is an effective neuropsychological tool for the assessment of 'real-life' decision-making in a laboratory environment. It has been employed in a wide range of circumstances, though researchers have sometimes employed real money reinforcers instead of the facsimile (or 'monopoly'-type) money used by. The present study investigated whether the type of reinforcer produced any differences in performance. There were no significant differences between the two conditions, though the Facsimile Money condition produced a greater range (and a higher standard deviation) than the Real Money condition. This finding is especially important when considering the Gambling Task as a tool in clinical neuropsychology--where there are risks, at the individual subject level, of both false positive and false negative classification errors.     

Religious coping strategies and spiritual transcendence

People use both positive and negative religious coping strategies, and do so in the context of how they perceive their relationship with God, which means that both require individuals to acquire some degree of self transcendence. This study attempted to show that self transcendence is incorporated in both positive and negative coping strategies. The sample consisted of 190 practising Anglicans and Catholics. They completed RCOPE from which two variables measuring positive coping and negative coping were then constructed, the Self Transcendence Scale (ST) the item content of which is largely positive and the Spiritual Transcendence Scale (STS) of the Temperament and Character Inventory, which acknowledges negative as well as positive experiences. They also completed a scale, God Cares, measuring a person's perception of God as caring. In a series of hierarchical regression analyses, all three variables, the perception of God as caring, and both the positive and negative coping variables predicted ST and all of its subscales except one. The positive coping variable largely predicted STS, the perception of God as caring variable less so and the negative coping variable not at all. The findings were interpreted as suggesting that both perceiving God as caring and using positive coping strategies limit the problematic feelings associated with negative coping strategies, allowing the self transcendence implicit in them to appear.     

Indirect Assessment of Anger Dispositions

Individual differences in aggressive motivation in frustration situations were conceptualized in terms of a frustration-anger association. The strength of this association was seen as being influenced by learning in the individual's frustration history and related to the individual's readiness to respond with anger. Several hypotheses were derived and tested with two groups, institutionalized delinquents and normal high school boys, using an indirect assessment technique. The technique, a set of items in story form, allowed for systematic variations of situational frustration and objective scoring of judged anger responses, but was indirect in that the subject's anger was inferred from his judgment of an imaginary boy's anger in the situation. The hypotheses received strong support from the data and the implications of these results both for the assessment technique and the theoretical statement were discussed.     

Paradoxical effects of education on the Iowa Gambling Task

Suitable normative information on the Iowa Gambling Task (IGT) is not currently available, though it is clear that there is great individual variability in performance on this assessment tool. Given that the task is presumed to measure the emotion-based learning systems that are thought to form the biological basis of 'intuition,' there is some reason to think that education (especially tertiary education) might explicitly de-emphasise the role of emotion-based learning in decision-making. This suggests the paradoxical finding that better-educated participants should show poorer performance on the IGT. We recruited 30 participants (all female, all aged 18-25) to participate in a 'real money' version of the IGT. There was no significant difference in performance in blocks 1-3 of the task (trials 1-60). However, there was a substantial effect of education on the final two blocks (trials 61-100), such that the less-well-educated participants produced twice as much of an improvement over baseline as did their university-educated colleagues. A range of possible explanations for this remarkable finding are discussed. The most likely appears to be that tertiary education specifically discourages the use of emotion-based learning systems in decision-making. These findings bear on the extent to which education has a role to play in our reliance on cognition and emotion in decision-making, including the likely role of education in the generation and maintenance of false beliefs.     

A positive emotional bias in confabulatory false beliefs about place

Some neurological patients with medial frontal lesions exhibit striking confabulations. Most accounts of the cause of confabulations are cognitive, though the literature has produced anecdotal suggestions that confabulations may not be emotionally neutral, having a ('wish-fulfilment') bias that shapes the patient's perception of reality in a more affectively positive direction. The present study reviewed every case (N = 16) of false beliefs about place reported in the neuroscientific literature from 1980 to 2000, with blind raters evaluating the 'pleasantness' of the patient's actual and confabulated locations. In each case the confabulated location was evaluated as more pleasant. This striking finding supports the claim that there may be a systematic affective bias in the false beliefs held by neurological patients with confabulation.
