Providing explicit information disrupts implicit motor learning after basal ganglia stroke

Despite their purported neuroanatomic and functional isolation, empirical evidence suggests that sometimes conscious explicit processes can influence implicit motor skill learning. Our goal was to determine if the provision of explicit information affected implicit motor-sequence learning after damage to the basal ganglia. Individuals with stroke affecting the basal ganglia (BG) and healthy controls (HC) practiced a continuous implicit motor-sequencing task; half were provided with explicit information (EI) and half were not (No-EI). The focus of brain damage for both BG groups was in the putamen. All of the EI participants were at least explicitly aware of the repeating sequence. Across three days of practice, explicit information had a differential effect on the groups. Explicit information disrupted acquisition performance in participants with basal ganglia stroke but not healthy controls. By retention (day 4), a dissociation was apparent--explicit information hindered implicit learning in participants with basal ganglia lesions but aided healthy controls. It appears that after basal ganglia stroke explicit information is less helpful in the development of the motor plan than is discovering a motor solution using the implicit system alone. This may be due to the increased demand placed on working memory by explicit information. Thus, basal ganglia integrity may be a crucial factor in determining the efficacy of explicit information for implicit motor-sequence learning.     

Groups for children traumatically bereaved by the attacks of September 11, 2001

The article reviews the use of debriefing and support groups for children who experienced the deaths of family members in the traumatic events of September 11, 2001. An overview of children's normal age-related responses to bereavement and of the special circumstances of trauma and grief provides the foundation for understanding the unique family and community stressors of 9/11 that impacted the children and group leaders. Stress-reduction exercises suitable for use with traumatized children in bereavement groups are presented together with specific drawing and written activities to encourage the processing of feelings.     

"Economic man" in cross-cultural perspective: behavioral experiments in 15 small-scale societies

Researchers from across the social sciences have found consistent deviations from the predictions of the canonical model of self-interest in hundreds of experiments from around the world. This research, however, cannot determine whether the uniformity results from universal patterns of human behavior or from the limited cultural variation available among the university students used in virtually all prior experimental work. To address this, we undertook a cross-cultural study of behavior in ultimatum, public goods, and dictator games in a range of small-scale societies exhibiting a wide variety of economic and cultural conditions. We found, first, that the canonical model - based on self-interest - fails in all of the societies studied. Second, our data reveal substantially more behavioral variability across social groups than has been found in previous research. Third, group-level differences in economic organization and the structure of social interactions explain a substantial portion of the behavioral variation across societies: the higher the degree of market integration and the higher the payoffs to cooperation in everyday life, the greater the level of prosociality expressed in experimental games. Fourth, the available individual-level economic and demographic variables do not consistently explain game behavior, either within or across groups. Fifth, in many cases experimental play appears to reflect the common interactional patterns of everyday life.     

Obsessive-Compulsive Disorder in the Media

Scholars have long been concerned that mass media depictions of those with mental disorders foster stigma. Research is needed extricating how particular disorders are represented and perceived, such as obsessive-compulsive disorder (OCD). This article examines what images of obsessions and compulsions exist in the media, and how persons interpret these. It employs two methods: qualitative in-depth interviews and content analysis. Data indicate the media represents obsessions and compulsions in distinguishable ways that both reinforce and complicate common media stereotypes of those with mental disorders—fostering a stigma hierarchy and having contradictory effects on mental health literacy.     

But we’re here to help! Positive buffers of the relationship between outsider incivility and employee outcomes

Incivility from sources outside the organization (e.g., customers, patients) is increasingly recognized as an important workplace stressor, having been linked to a variety of negative outcomes. It is therefore becoming more important to understand not only the negative effects of outsider incivility, but also potential buffers of these negative effects. As such, the current study sought to explore the impact of outsider incivility directed towards emergency workers (called “victim” incivility) and to identify and test potential positive psychological buffers of the relationship between victim incivility and burnout, physical symptoms and objective absenteeism. Specifically, utilizing a resource perspective, we sought to determine whether work engagement and empathy buffered these negative effects. Survey data from 208 firefighters at two time points showed that victim incivility predicted burnout, physical symptoms and absenteeism, and that both engagement and empathy ameliorated some negative outcomes of victim incivility, including burnout and physical symptoms. Theoretical and practical implications of the research are discussed and areas for future research are proposed.     

Mindfulness,physical impairment and psychological well-being in people with amyotrophic lateral sclerosis

Objective: Mindfulness is the process of actively making new distinctions, rather than relying on habitual or automatic categorisations from the past. Mindfulness has been positively associated with physical well-being, better recovery rates from disease or infections, pain reduction and overall quality of life (QOL). Amyotrophic lateral sclerosis (ALS) is a rare, progressive and fatal neurodegenerative disease, clinically characterised by progressively increasing weakness leading to death, usually within five years. There is presently no cure for ALS, and it is considered one of the most genetically and biologically driven illnesses. Thus far, the aims of psychological studies on ALS have focused on understanding patient – and, to a lesser extent, caregiver – QOL and psychological well-being. No previous study has investigated the influence of psychological factors on ALS.

Methods: A sample of 197 subjects with ALS were recruited and assessed online twice, with a duration of four months between the two assessments. Assessments included measurements of trait mindfulness, physical impairment, QOL, anxiety and depression. The influence of mindfulness as predictor of changes in physical impairments was evaluated with a mixed-effects model.

Results: Mindfulness positively influenced the change of physical symptoms. Subjects with higher mindfulness experienced a slower progression of the disease after four months. Moreover, mindfulness at first assessment predicted higher QOL and psychological well-being.

Conclusions: The available data indicate that a psychological construct – mindfulness – can attenuate the progress of a disease that is believed to be almost solely biologically driven. The potential implications of these results extend well beyond ALS.     

Internet-Based,Unproctored Assessments on Mobile and Non-Mobile Devices: Usage,Measurement Equivalence,and Outcomes

Purpose

The purpose of this study was to determine the usage rates, measurement equivalence, and potential outcome differences between mobile and non-mobile device-based deliveries of an unproctored, non-cognitive assessment.

Design/Methodology/Approach

This study utilized a quasi-experimental design based on archival data obtained from applicants who completed a non-cognitive assessment on a mobile (n = 7,743; e.g., smartphones, tablet computers) or non-mobile (n = 929,341; e.g., desktop computers) device as part of an operational, high-stakes pre-employment selection process.

Findings

One percent of applicants used mobile devices to complete the assessment. Multiple-group confirmatory factor analysis indicated the assessment was equivalent across mobile and non-mobile devices at the configural, metric, scalar, and latent mean levels. A comparison of observed score means using one-way and factorial ANOVAs demonstrated that the use of mobile and non-mobile devices did not produce any practically significant score differences on the assessment across devices or applicant demographic subgroups.

Implications

Industry and technological trends suggest mobile device usage will only increase. Thus, demonstrating that mobile device functionality and hardware characteristics do not change the psychometric functioning or applicant outcomes for a non-cognitive, text-based selection assessment is critical to talent assessment.

Originality/Value

This study provides the first empirical examination of the usage of mobile devices to complete talent assessments and their impact on assessment properties and applicant outcomes, and serves as the foundation for future research and application of this growing technological trend in pre-employment assessment.

     

Frege's Puzzle for Perception

According to an influential variety of the representational view of perceptual experience—the singular content view—the contents of perceptual experiences include singular propositions partly composed of the particular physical object(s) a given experience is about or of. The singular content view faces well‐known difficulties accommodating hallucinations; I maintain that there is also an analogue of Frege's puzzle that poses a significant problem for this view. In fact, I believe that this puzzle presents difficulties for the theory that are unique to perception in that strategies that have been developed to respond to Frege's puzzle in the case of belief cannot be employed successfully in the case of perception. Ultimately, I maintain that this perceptual analogue of Frege's puzzle provides a compelling reason to reject the singular content view of perceptual experience.

The punishment that sustains cooperation is often coordinated and costly

Experiments are not models of cooperation; instead, they demonstrate the presence of the ethical and other-regarding predispositions that often motivate cooperation and the punishment of free-riders. Experimental behavior predicts subjects' cooperation in the field. Ethnographic studies in small-scale societies without formal coercive institutions demonstrate that disciplining defectors is both essential to cooperation and often costly to the punisher.
