Jurors Report that Risk Measure Scores Matter in Sexually Violent Predator Trials,but that Other Factors Matter More

After deliberating to a verdict, jurors (N = 462) from 40 sexually violent predator (SVP) trials completed a questionnaire asking them to rate the extent to which risk measure scores, diagnoses, expert witness testimony, and offender characteristics described during the trials influenced their commitment decisions. Jurors reported that offenders' sexual offending history, failure to change, and lack of remorse had the strongest influence on their commitment decisions. They reported that testimony about risk instrument scores (e.g., Static-99) and psychopathy had less influence on their decisions, but those who did report being influenced by instrument results were especially likely to view the offender as being at a high risk for reoffending. Overall, findings suggest that SVP jurors view risk measure results as important, but not as important as other offender, offense, and testimony characteristics, including some that have limited relevance to recidivism risk. Thus, findings also suggest that experts may need to better educate jurors regarding factors that do and do not relate to recidivism risk. Copyright © 2015 John Wiley & Sons, Ltd.     

Disorders of Eating in the Elderly

The most common eating disorder in the elderly in both community and hospital settings is food refusal. This may lead to weight loss and malnutrition with all the adverse consequences on independence and function. The management of disorders of eating in the elderly is a diagnostic and therapeutic challenge, requiring the combined skills of the medical and nursing staff. The causes are often multifactorial and require careful and repeated assessment of the patient's social, psychological, and medical history. Approach to treatment involves these factors, as well as ethical and cultural considerations. Eating is the most basic biological drive for survival in nature. In human societies there are additional cultural and social aspects that may override this instinct, as in the case of hunger strikes for political motives. In the elderly, food is one of the major sources of possible pleasure and it is the challenge for health providers to try and give this enjoyment to their patients for as long as possible.     

Preference or ability: Exploring the relations between risk preference,personality, and cognitive abilities

Key issues in the behavioral sciences are if there exist stable risk preferences that generalize across domains and if these are best measured by revealed risk preference (RRP) in behavioral decision tasks or by surveys eliciting stated risk preference (SRP). We applied network analysis to data from a representative Swedish sample to investigate the relations between RRP, SRP, personality characteristics, and cognitive abilities, using in total over 70 measurements. The results showed that different measures of RRP were poorly intercorrelated and formed a community together with measures of numerical and cognitive abilities. Measures of SRP were weakly correlated with measures of RRP and identified in a distinctly separate community, along with personality characteristics and gender. The ensuing analyses provided support for a model suggesting that RRPs are contaminated by demands on numerical and cognitive abilities. RRPs may thus suffer from poor construct validity, whereas SRPs may better capture people's everyday risk preferences because they are related to more stable traits.

Should research experience be used for selection into graduate school: A discussion and meta‐analytic synthesis of the available evidence

Prior research experience is widely considered by graduate school admissions committees in the United States of America. Here, we use meta‐analytic methods and data from 18 unique samples and a total sample size of 3,525 students to shed light on the validity of prior research experience as a predictor of graduate school performance. Prior research experience was largely unrelated to academic performance (ρ = .01, k = 8, N = 1,419), degree attainment (ρ = .05, k = 3, N = 140), professional/practice performance (ρ = .06, k = 4, N = 1,120), and publication performance (ρ = .11, k = 7, N = 1,094). We also discuss whether consideration of prior research experience may unfairly disadvantage the students with lower levels of SES, students with childcare or eldercare responsibilities, and students from institutions at which research opportunities are limited.     

Functional and connectivity changes during working memory in Huntington’s disease: 18 month longitudinal data from the IMAGE-HD study

Background

This study aimed to characterize, for the first time, 18 month longitudinal changes in both functional activation and functional connectivity during working memory in premanifest Huntington’s disease (pre-HD) and symptomatic HD (symp-HD).

Methods

Functional magnetic resonance imaging (fMRI) was used to investigate longitudinal changes in neuronal activity during working memory performance via an N-BACK task (0-BACK and 1-BACK) in 27 pre-HD, 17 symp-HD, and 23 control participants. Whole-brain analysis of activation and region-of-interest analysis of functional connectivity was applied to longitudinal fMRI data collected at baseline and 18 months follow-up.

Results

Compared with controls, the pre-HD group showed significantly increased activation longitudinally during 1-BACK versus 0-BACK in the lateral and medial prefrontal, anterior cingulate, primary motor, and temporal areas cortically, and caudate and putamen subcortically. Pre-HD far from onset, compared with controls, showed further longitudinal increases in the right and left dorsolateral prefrontal cortex (DLPFC). Longitudinal increased activation in anterior cingulate and medial primary motor areas were associated with disease burden in the pre-HD group. Moreover, in pre-HD increased activation over time in primary motor and putamen regions were associated with average response time during 1-BACK performance. During 1-BACK, functional connectivity between the right DLPFC and posterior parietal, anterior cingulate, and caudate was significantly reduced over 18 months only in the pre-HD group.

Conclusions

Longitudinal reductions in connectivity over 18 months may represent an early signature of cortico-cortical and cortico-striatal functional disconnectivity in pre-HD, whereas the concomitant increased cortical and subcortical activation may reflect a compensatory response to the demands for cognitive resources required during task performance. Our findings demonstrate that functional imaging modalities have the potential to serve as sensitive methods for the assessment of cortical and subcortical responses to future treatment measures.     

The heart beat does not make us tick: The impacts of heart rate and arousal on time perception

According to popular models of human time perception, variations in prospective timing are caused by two factors: the pulse rate of an internal pacemaker and the amount of attention directed to the passage of time. The results concerning the effect of attention on subjective timing have been conclusive, but the mechanisms that drive the pacemaker are still far from being understood. In two experiments, we examined the impact of two factors that in the existing literature on human time perception have been argued to affect such a pacemaker: arousal and heart rate. Experienced arousal and heart rate were varied independently by means of specific physical exercises: (a) A muscle exercise increased arousal and heart rate; (b) a breath-holding exercise increased arousal but decreased heart rate; and (c) in the control condition, arousal and heart rate were held constant. The results indicate that increased subjective arousal leads to higher time estimates, whereas heart rate itself has no relevant impact on time perception. The results are discussed with respect to the underlying mechanisms of prospective time perception.     

Seeing what you hear: Visual feedback improves pitch recognition

The present study examined the effect of visual feedback on the ability to recognise and consolidate pitch information. We trained two groups of nonmusicians to play a piano piece by ear, having one group receiving uninterrupted audiovisual feedback, while allowing the other only to hear, but not see their hand on the keyboard. Results indicate that subjects for whom visual information was deprived showed significantly poorer ability to recognise pitches from the musical piece they had learned. These results are interesting since pitch recognition ability would not intuitively seem to rely on visual feedback. In addition, we show that subjects with previous experience in computer touch-typing made fewer errors during training when trained with no visual feedback, but did not show improved pitch recognition ability posttraining. Our results demonstrate how sensory redundancy increases robustness of learning, and further encourage the use of audiovisual training procedures for facilitating the learning of new skills.
