Are Actual and Perceived Intellectual Self‐enhancers Evaluated Differently by Social Perceivers?

Do actual and perceived self‐enhancement entail differing social impressions (i.e. interpersonal evaluations)? Actual self‐enhancement represents unduly positive self‐views, as gauged by an objective criterion (in this case, IQ scores), whereas perceived self‐enhancement involves the extent to which an individual is seen by informants (i.e. peers or observers) as self‐enhancing. In an online survey (N = 337), a laboratory experiment (N = 75), and a round‐robin study (N = 183), we tested the effects of actual and perceived intellectual self‐enhancement on (informant‐rated) emotional stability, social attractiveness, and social influence. Actual self‐enhancers were rated as emotionally stable, socially attractive, and socially influential. High perceived self‐enhancers were judged as socially influential, whereas low‐to‐moderate perceived self‐enhancers were deemed emotionally stable and socially attractive. Privately entertained, illusory positive (even extreme) self‐beliefs confer social benefits, whereas being perceived as self‐enhancing buys social influence at the cost of being despised.

Regional brain activity change predicts responsiveness to treatment for stuttering in adults

Developmental stuttering is known to be associated with aberrant brain activity, but there is no evidence that this knowledge has benefited stuttering treatment. This study investigated whether brain activity could predict progress during stuttering treatment for 21 dextral adults who stutter (AWS). They received one of two treatment programs that included periodic H₂¹⁵O PET scanning (during oral reading, monologue, and eyes-closed rest conditions). All participants successfully completed an initial treatment phase and then entered a phase designed to transfer treatment gains; 9/21 failed to complete this latter phase. The 12 pass and 9 fail participants were similar on speech and neural system variables before treatment, and similar in speech performance after the initial phase of their treatment. At the end of the initial treatment phase, however, decreased activation within a single region, L. putamen, in all 3 scanning conditions was highly predictive of successful treatment progress.     

Inter-hemispheric remapping between arm proprioception and vision of the hand is disrupted by single pulse TMS on the left parietal cortex

Parietal cortical areas are involved in sensori-motor transformations for their respective contralateral hemifield/body. When arms of the subjects are crossed while their gaze is fixed straight ahead, vision of the hand is processed by the hemisphere ipsilateral to the arm position and proprioception of the arm by the contralateral hemisphere. It induces interhemispheric transfer and remapping. Our objective was to investigate whether a single pulse TMS applied to the left parietal cortical area would disturb interhemispheric remapping in a similar case, and would increase a simple reaction time (RT) with respect to a control single pulse TMS applied to the frontal cortical area. Two LED were superimposed and located in front of the subjects on the saggital axis. Subjects were asked to carefully fixate on these LED during each trial. The lighting of the red LED was used as a warning signal. Following the green one was illuminated after a variable delay and served as a go-signal. The hand for the response was determined before the start of each trial. TMS was applied to the left parietal, the left frontal cortical areas, or not applied to the subject. Results revealed that: (1) Irrespective of its location, single pulse TMS induced a non-specific effect similar to a startle reflex and reduced RT substantially (15 ms on average) with respect to a control condition without TMS (mean value = 153 ms). (2) Irrespective of TMS, RT were shorter when the right or the left hand was positioned in the right visual hemi-field (i.e. normal and crossed positions respectively). (3) Finally, RT increased when single pulse TMS was applied to the left parietal area and when hands were crossed irrespective of which hand was used. We concluded that interhemispheric sensori-motor remapping was disrupted by a single pulse TMS that was applied to the left parietal cortex. This effect was also combined with some visual attention directed towards the hand located on the right visual hemi-field.     

Linear-parabolic shift of initially sharp interface in AB diffusion couple above the ordering temperature

It is shown that initially sharp interface in AB diffusion couple, above the ordering temperature, can shift with anomalous kinetics, i.e. deviations from the parabolic growth kinetics are possible. The initial slopes of the shift versus time functions can be even unity for large diffusion asymmetry (the ratio of diffusion coefficients of the parent materials in orders of magnitude) and gradually decrease to 0.5 at larger distances (longer times). This is in accordance with earlier results obtained in phase separating systems. It is shown that from the results of simulations the crossover thickness, X*, between the linear and parabolic regimes can also be calculated, and the applicability of the linear–parabolic law is confirmed. Furthermore, it is illustrated that the crossover thickness depends exponentially on the diffusion asymmetry parameter, with the exponent close to the value obtained from analytical estimations.     

Social aspects of career choice from the perspective of habitus theory

The concept of habitus designates a cognitive structure that is socially embedded and can give valuable insight into the social influences on career choice. A study investigating the relationship of habitus to career choice is presented in a sample of Icelandic youth aged 19–22 (N = 476). Measures of habitus were developed on the basis of reported cultural and leisure activities. The analysis of leisure and cultural items progressed in two steps: factor analysis and cluster analysis. The clusters constitute the four different habitus groups: Pop and fashion, Sports and rock, Music, and Literature. Correspondence factor analysis showed that the habitus groups (clusters) were related to other social variables, such as gender and class; validating habitus theory. Additionally, habitus measures were strongly linked to career variables, such as occupational perception and preferred future occupation. The results support previous research in showing that habitus theory is relevant to career counseling theory and can be a basis of understanding the relationship between social structure and career choice.     

The Design and Evaluation of a Hope Enhancement Programme for Adults

The study evaluated the effectiveness of a hope enhancement programme for a group of adults and its impact on general psychological well-being. The intervention programme focused on participants' abilities to set feasible goals, planning ways to reach those goals (pathways) and increase determination and motivation (agency) to reach these goals. The workshop-format programme, consisted of six two-hour sessions conducted over five days. A pre and post-test design included an experimental group (n = 8), control group (n = 8) and ‘chat group’ (n = 8). Findings indicated that the programme increased hope levels of the experimental group as indicated by the Hope Scale and the Hopefulness Subscale of the Hunter Opinions and Personal Expectations Scale. Well-being also improved as indicated by a significant increase in sense of coherence along with a positive change in satisfaction with life. Recommendations for future research were made.     

Will the “Real Boy” Please Behave: Dosing Dilemmas for Parents of Boys with ADHD

The use of Ritalin and other stimulant drug treatments for attention-deficit hyperactivity disorder (ADHD) raises distinctive moral dilemmas for parents; these moral dilemmas have not been adequately addressed in the bioethics literature. This paper draws upon data from a qualitative empirical study to investigate parents' use of the moral ideal of authenticity as part of their narrative justifications for dosing decisions and actions. I show that therapeutic decisions and actions are embedded in valued cultural ideals about masculinity, self-actualization and success, as well as in moral conceptions of authenticity and personal freedom. I argue that this investigation of parents' moral justifications and dosing dilemmas raises questions about the validity of authenticity as a transcendent moral principle. Moreover, this study demonstrates that in order to be relevant, bioethical analysis of neurocognitive enhancement must engage with ground-up studies of moral principles and decision-making in context.     

Depression and Spirituality in Australian Aged Care Homes

SUMMARY

A national survey of Australian aged care homes has found that between 40% and 60% of high care residents and 25% to 51 % of low care residents are depressed, depending on the method used to assess depression. While this survey did not specifically include items on spirituality, an analysis based the Geriatric Depression Scale question “Do you feel that your life is empty?” provides some insights into the type of person who may benefit from spiritual help.

The view is expressed that those committed to the provision of spiritual care must be more assertive in making the positive contribution to the reduction in depression that empirical research carried out over the last thirty years suggests is possible. The basic step of identifying those who are ready to talk about spiritual matters and who are depressed is offered as a starting point and some ways of doing this are described.     

Scene layout from ground contact,occlusion, and motion parallax

An important factor in determining perceived scene layout is optical contact between objects and the ground surface (“ground contact”). The relation between ground contact and occlusion was investigated in four experiments with stationary and motion parallax scenes containing a pole that occluded or was occluded by one or more cylinders. Some judgements were inconsistent with occlusion in stationary scenes, but judgements were consistent with occlusion in motion parallax scenes. When the range of object positions consistent with occlusion did not include the positions specified by ground contract or by motion parallax, the ground contact and motion parallax information still had a quantitative effect on the perceived position of the object within the range consistent with occlusion. These results demonstrate a cooperative interaction between ground contact, occlusion, and motion parallax in determining perceived layout in 3-D scenes.     

Exercise after work,psychological mediators,and affect: A day-level study

In this diary study, we tested the recovery potential of exercise activities during leisure time and examined the psychological mechanisms underlying the relation between exercise activities and affect. We hypothesized that spending time on exercise activities after work will be related to subsequent affect in the evening, and that psychological detachment from work, sense of belonging, and physical self-perceptions explain why exercise activities are related to subsequent affect. One-hundred and twenty-six participants from diverse occupations completed a diary twice a day over five consecutive work days. Multilevel analyses showed that exercise activities after work were related to positive, but not to negative affect in the evening. As proposed, psychological detachment, sense of belonging, and physical self-perceptions mediated the relation between exercise activities after work and positive affect in the evening.
