Musical rhythm discrimination explains individual differences in grammar skills in children

This study considered a relation between rhythm perception skills and individual differences in phonological awareness and grammar abilities, which are two language skills crucial for academic achievement. Twenty‐five typically developing 6‐year‐old children were given standardized assessments of rhythm perception, phonological awareness, morpho‐syntactic competence, and non‐verbal cognitive ability. Rhythm perception accounted for 48% of the variance in morpho‐syntactic competence after controlling for non‐verbal IQ, socioeconomic status, and prior musical activities. Children with higher phonological awareness scores were better able to discriminate complex rhythms than children with lower scores, but not after controlling for IQ. This study is the first to show a relation between rhythm perception skills and morpho‐syntactic production in children with typical language development. These findings extend the literature showing substantial overlap of neurocognitive resources for processing music and language.

Functional principal components analysis of workload capacity functions

Workload capacity, an important concept in many areas of psychology, describes processing efficiency across changes in workload. The capacity coefficient is a function across time that provides a useful measure of this construct. Until now, most analyses of the capacity coefficient have focused on the magnitude of this function, and often only in terms of a qualitative comparison (greater than or less than one). This work explains how a functional extension of principal components analysis can capture the time-extended information of these functional data, using a small number of scalar values chosen to emphasize the variance between participants and conditions. This approach provides many possibilities for a more fine-grained study of differences in workload capacity across tasks and individuals.     

Sovereign Debt

This essay examines the concept of sovereign debt in both political‐economic and theological registers. Elaborating the dynamics of monetary economy, I demonstrate how postures of indebtedness characterize the relationship between sovereign power and the governed. While taxation signals the debt of obedience and fealty owed to sovereignty, the monetary circuit reveals that sovereign power exists in a state of indebtedness to the governed. The morally valenced proximity between debt and guilt helps to perpetuate such relations. Tracing these resonances and resemblances in the theological realm, I consider the centrality of debt as a structuring principle in key soteriological traditions within Christian thought. Not only does God appear to uphold debt logic, but God, I claim, becomes identified with debt and marked as a debtor. The divine sovereign as debtor and as enforcing debt provides cues for earthly sovereigns and legitimates cultures of debt. In light of the theopolitical legacy in the West, the mutual influence between theology and the political realm, refiguring this set of influential theological concepts may prove helpful in decentering debt as a governing principle in modern life.     

Changing categorization of self can change emotions about outgroups

Drawing on Intergroup Emotions Theory [Mackie, D. M., Maitner, A. T., & Smith, E. R. (in press). Intergroup emotions theory. In T.D. Nelson (Ed.), Handbook of Prejudice, Stereotyping, and Discrimination, New York: Erlbaum.], we propose that a perceiver’s emotional reactions toward other social groups can change in response to situationally induced shifts in self-categorization. American students were led to self-categorize as Americans or as students and reported their anger and respect towards Muslims and police. Results indicated that in reaction to Muslims, participants felt more anger and less respect when categorized as Americans than when categorized as students. In reaction to police, participants felt less anger and more respect when categorized as Americans than when categorized as students. These results support and extend IET, and suggest that in addition to prejudice reduction interventions that focus on recategorization of the target, perceiver recategorization of the self is a viable means of changing emotional reactions to social targets.     

Dissociated control as a signature of typological variability in high hypnotic suggestibility

This study tested the prediction that dissociative tendencies modulate the impact of a hypnotic induction on cognitive control in different subtypes of highly suggestible individuals. Low suggestible (LS), low dissociative highly suggestible (LDHS), and high dissociative highly suggestible (HDHS) participants completed the Stroop color-naming task in control and hypnosis conditions. The magnitude of conflict adaptation (faster response times on incongruent trials preceded by an incongruent trial than those preceded by a congruent trial) was used as a measure of cognitive control. LS and LDHS participants displayed marginally superior up-regulation of cognitive control following a hypnotic induction, whereas HDHS participants’ performance declined. These findings indicate that dissociative tendencies modulate the influence of a hypnotic induction on cognitive control in high hypnotic suggestibility and suggest that HS individuals are comprised of distinct subtypes with dissimilar cognitive profiles.     

The Rutgers Arm, a rehabilitation system in virtual reality: a pilot study.

Stroke is one of the leading causes of death and disability worldwide. Its prevalence calls for innovative rehabilitation methods. The Rutgers Arm is a novel upper extremity rehabilitation system consisting of a low-friction table, three-dimensional (3D) tracker, custom forearm support, PC workstation, library of Java 3D virtual reality (VR) exercises, clinical database module, and a tele-rehabilitation extension. The system was tested on a chronic stroke subject, under local and tele-rehabilitation conditions, over 5 weeks of training. Results show improvements in arm motor control and shoulder range of motion, corresponding to improved Fugl-Meyer test scores. Exercise duration, level of difficulty, and patient motivation were maintained under tele-rehabilitaion. A 1-week retention trial showed that gains were maintained.

Evaluative Aspects of Creative Thought: Effects of Appraisal and Revision Standards

Recent research has begun to stress the influence of evaluation on creative thought. The authors begin this article by arguing that the evaluation of new ideas is a complex process involving forecasting, appraisal, and revision, where different standards might be applied to different ideas during appraisal and revision. The influence of appraisal and revision standards on creative problem solving was examined by asking 148 undergraduates to appraise and revise highly original, original, and nonoriginal ideas generated for an advertising campaign under conditions in which the standards to be applied stressed the generation of new ideas or under conditions in which the standards to be applied stressed efficiency of current operations. It was found that better plans for these advertising campaigns were obtained when generative, or innovative, criteria were applied to less original ideas and when implementation efficiency, or operating, criteria were applied to more original ideas. It was concluded that evaluation may serve to remediate deficiencies in ideas but that the standards applied must vary with the nature of the idea and the context in which it is to be implemented
