Perception in action: The impact of sensory information on sensorimotor synchronization in musicians and non-musicians

The present study aimed at investigating to what extent sensorimotor synchronization is related to (i) musical specialization, (ii) perceptual discrimination, and (iii) the movement’s trajectory. To this end, musicians with different musical expertise (drummers, professional pianists, amateur pianists, singers, and non-musicians) performed an auditory and visual synchronization and a cross-modal temporal discrimination task. During auditory synchronization drummers performed less variably than amateur pianists, singers and non-musicians. In the cross-modal discrimination task drummers showed superior discrimination abilities which were correlated with synchronization variability as well as with the trajectory. These data suggest that (i) the type of specialized musical instrument affects synchronization abilities and (ii) synchronization accuracy is related to perceptual discrimination abilities as well as to (iii) the movement’s trajectory. Since particularly synchronization variability was affected by musical expertise, the present data imply that the type of instrument improves accuracy of timekeeping mechanisms.     

“Why didn’t you just ask?” Underestimating the discomfort of help-seeking

Across four studies we demonstrate that people in a position to provide help tend to underestimate the role that embarrassment plays in decisions about whether or not to ask for help. As a result, potential helpers may overestimate the likelihood that people will ask for help (Studies 1 and 2). Further, helpers may be less inclined to allocate resources to underutilized support programs than help-seekers because they are less likely to attribute low levels of use to help-seekers’ concerns with embarrassment (Study 3). Finally, helpers may misjudge the most effective means of encouraging help-seeking behavior - emphasizing the practical benefits of asking for help, rather than attempting to assuage help-seekers’ feelings of discomfort (Study 4).     

A systematic analysis of distressing near-death experience accounts

ABSTRACT

Near-death experiences (NDEs) are usually associated with positive affect, however, a small proportion are considered distressing. We aimed to look into the proportion of distressing NDEs in a sample of NDE narratives, categorise distressing narratives according to Greyson and Bush’s classification (inverse, void or hellish), and compare distressing and “classical” NDEs. Participants wrote down their experience, completed the Memory Characteristics Questionnaire (assessing the phenomenology of memories) and the Greyson scale (characterising content of NDEs). The proportion of suicidal attempts, content and intensity of distressing and classical NDEs were compared using frequentist and Bayesian statistics. Distressing NDEs represent 14% of our sample (n?=?123). We identified 8 inverse, 8 hellish and 1 void accounts. The proportion of suicide survivors is higher in distressing NDEs as compared to classical ones. Finally, memories of distressing NDEs appear as phenomenologically detailed as classical ones. Distressing NDEs deserve careful consideration to ensure their integration into experiencers’ identity.     

Principles of Occupational Therapy Group Outcome Assessment in Mental Health

In today's penurious health care climate, occupational therapists must scrutinize their practice and substantiate their interventions in order to remain viable service providers. This article proposes a method of occupational therapy outcomes assessment in mental health care that is rooted in client-centered functional outcomes. Since little consensus exists on which instruments are most effective, this article begins with an outline of broadly accepted principles for assessment of patient outcomes in mental health. Next, we describe a practical method for selecting outcomes measures in interdisciplinary settings. Finally, we offer pragmatic solutions to address barriers to outcome assessment.     

Sifting through the Hyperbole: One Hundred Years of Marijuana Coverage in The New York Times

The contemporary media has often portrayed marijuana as a “slacker drug”; however, this portrayal is somewhat novel. Several scholars have argued in the early 1900s, especially in the 1930s, the media often associated marijuana with violence and mental illness. Another common argument was that marijuana was associated with Mexican immigrants. Conversely, other researchers have argued that these reports were overblown and media accounts of marijuana were not very common until recent years. The current study utilizes recently available on-line archives to conduct a more comprehensive test of how exactly marijuana was depicted in The New York Times from 1851–1950.     

Predictors of quality of life enjoyment and satisfaction in individuals living with HIV and AIDS in a resource-constrained setting in South Africa

The burden of HIV disease is concentrated in sub-Saharan Africa, particularly in South Africa (SA). Whilst there have been many studies conducted on the biomedical and socio-psychological aspects of HIV and AIDS, insufficient attention has been paid to the quality of life of those infected with the virus. The primary purpose of the study was to determine the predictors of quality of life enjoyment and satisfaction (Q-LES) among individuals infected with HIV. A battery of questionnaires, which included the Hospital Anxiety and Depression Scale (HADS) and the Quality of Life Enjoyment and Satisfaction Questionnaire (Q-LES-Q), were administered to 121 participants. Data was analysed using SPSS. Of the total sample (n = 121), 74% were females. The study found that a large proportion (49.5%) of the sample within the age group 25–49 years old experienced psychological distress. Those who were not on antiretroviral treatment (ART) were significantly affected (66%). Psychological distress was significantly prevalent among HIV positive individuals and also the strongest predictor of Q-LES among these individuals.     

Strategy Shifts and Expertise in Solving Transformation Rule Problems

The acquisition of expertise in formal problem solving has been assumed to involve either a shift from backwards to forwards inference, or a shift from unguided to guided forwards inference. In a longitudinal study, the acquisition of formal problem-solving expertise was investigated. Participants were tested as novices before undertaking controlled practice in the problem domain which involved transformation rule problems, and were finally tested as experts. The direction of inference in problem solutions was found to be inadequate to describe the strategic differences between novices and experts. Therefore, a new solution coding system was applied, based on atomic components of problem solution. Analysis of novice and expert solutions revealed no systematic strategy in the novice stage—solutions were confused and contained unproductive steps and backtracking. Several strategies were found in the expert solutions, but they did not agree with previously reported results. It was therefore proposed that the acquisition of expertise does not involve a change from one specific solution strategy to another, but rather the development of an efficient strategy, which can differ between participants.     

Factor Structure of the Torrance Tests of Creative Thinking Verbal Form B in a Spanish‐speaking Population

The objective of this study was to compare, through a Confirmatory Factor Analysis, two different theoretical models that explain the operationalized creativity construct with the Verbal Torrance Tests of Creative Thinking (TTCT), Form B. Model 1 is represented by six factors which correspond to each activity and its respective indicators while Model 2 is integrated by three factors which correspond to each TTCT ability (i.e., Fluency, Originality, and Flexibility) and the corresponding indicators for each variable. The study was carried out with a sample consisting of 432 Spanish‐speaking youngsters of both sexes aged 15–26. According to the research findings, the model which showed the most satisfactory fit identifies six correlated factors that correspond to each of the activities proposed (χ² = 414.48; df = 116; χ²/df = 3.57; GFI = .90; NFI = .95; CFI = .96 and RMSEA = .077). These results are discussed according to its psychometric implications for the construct assessment in different fields.     

On Smilansky’s Defense of Prepunishment: A Response to Robinson

Philosophia - In a 2010 paper published in this journal, Robinson responded to Smilansky’s argument that compatibilists do not have a principled reason to reject prepunishment. Smilansky...
