Developmental differences in risk factors for suicide attempts between ninth and eleventh graders

In order to identify differences in risk factors for suicide attempts throughout adolescence, this study utilized a school-based survey of ninth (n = 1,192) and eleventh graders (N = 1,055). Suicide attempts were associated with cigarette and alcohol use, family violence, and depression for ninth graders and with illicit drug use, school violence, and sexual abuse for eleventh graders, while having friends was protective for both groups. Additionally, having more than one risk factor imparted an exponential risk for suicide attempts (ninth > eleventh graders). The differences detected are consistent with developmental changes of adolescence and represent important information for identification of at-risk youth.     

Does each hemisphere monitor the ongoing process in the contralateral one?

The present study was conducted to examine hemispheric division of labor in the initial processing and error monitoring in tasks for which hemispheric specialization exists. We used lexical decision as a left hemisphere task and bargraph judgment as a right hemisphere task, and manipulated cognitive load. Participants had to respond to one of two stimuli presented to both visual fields and were instructed to correct their errors. To achieve enough correctable errors, participants were encouraged to respond quickly by using a bonus system. The results showed the classical asymmetry for initial responses in both tasks and reversed asymmetry for corrections in the bargraph task at both load conditions, and in the lexical decision task at the high load condition. The results suggest that each hemisphere monitors the ongoing process in the contralateral one and that the dissociation of initial process and its monitoring grows with load of task.     

Music Hath Charms … And Can Influence Helpfulness1

Eighty university students, half men and half women, were distributed evenly among 4 conditions in a one-way design. Three of the groups heard a seven-minute-long musical selection, either soothing, stimulating, or aversive in nature, while the remaining subjects were not exposed to any music and sat still. Ratings indicated that the soothing and stimulating music created some- what different positive moods while the aversive music tended to arouse negative feelings. Those who heard the soothing music were most apt to be helpful immediately afterwards, significantly more so than the aversive music or no music subjects, perhaps because of the ideas evoked by this selection.     

Predictors of Placement Outcomes in Treatment Foster Care: Implications for Foster Parent Selection and Service Delivery

Treatment foster care (TFC) is a normalizing environment in which to treat those children whose particular needs are not addressed in traditional foster care and for whom an institutional setting is a restrictive and unnecessary alternative. However, when the foster care placements of these emotionally and behaviorally disturbed children fail, as they often do, the children are shifted from one home to another without the opportunity to experience permanence or emotional attachment, resulting in poor adjustment to foster care. Placement stability, which depends in part upon effective matching of foster children with potential foster families, is critical for achieving positive outcomes in TFC. Yet, there is a dearth of information to guide placement agencies in making decisions about matching foster children with families. Moreover, once a successful match has been made, it is equally vital that service delivery be of high quality so that permanence is maintained. We review research on the predictors of positive outcomes in foster care, focusing on studies involving emotionally or behaviorally disturbed children, and provide recommendations for selecting foster parents and for ensuring high quality foster care services and placement stability.     

Enjoyment of Work and Driven to Work as Motivations of Job Crafting: Evidence from Japan and China

This research contributes to our understanding of job crafting by investigating the role of “enjoyment of work” and “driven to work” as job-crafting motivations. A total of 154 supervisor–employee dyads were surveyed. Enjoyment of work and driven to work were supported as motivators of job crafting. An interaction effect was observed, with low driven to work weakening the relationship between enjoyment of work and job crafting. Job crafting mediated the relationship between the two motivators and job performance. We add to researchers’ understanding of motivations for job crafting while making the first attempt to explore the job-crafting phenomenon in East Asia.

Percepts to recollections: insights from single neuron recordings in the human brain

Transformation of experience into memories that can guide future behavior is a common ability across species. However, only humans can declare their perceptions and memories of experienced events (episodes). The medial temporal lobe (MTL) is central to episodic memory, yet the neuronal code underlying the translation from sensory information to memory remains unclear. Recordings from neurons within the brain in patients who have electrodes implanted for clinical reasons provide an opportunity to bridge physiology with cognitive theories. Recent evidence illustrates several striking response properties of MTL neurons. Responses are selective yet invariant, associated with conscious perception, can be internally generated and modulated, and spontaneously retrieved. Representation of information by these neurons is highly explicit, suggesting abstraction of information for future conscious recall.     

Assessment of cognitive domains during treatment with OROS methylphenidate in adolescents with ADHD

Aim: To psychometrically assess cognitive domains in adolescents with ADHD during long-term open treatment with robust dosing of extended-release methylphenidate (OROS MPH).

Methods: Data were derived from a prospective clinical study of adolescent ADHD, employing the Cambridge Neuropsychological Test Automated Battery (CANTAB), before and after up to one year of treatment with OROS MPH. In the absence of placebo control, a similar age and gender group of youth without ADHD served as comparators.

Results: During the course of treatment with OROS MPH, ADHD youth’s performance significantly improved across multiple CANTAB tasks, including spatial working memory, rapid visual processing, verbal recognition memory, set shifting, and inhibition/vigilance. ADHD subjects’ scores in several CANTAB tasks, including spatial working memory, planning, and set shifting, were significantly more impaired at baseline compared to the non-ADHD comparison group; these significant differences were no longer seen at endpoint.

Conclusions: Statistically significant improvements in multiple cognitive domains were observed in a sample of adolescents with ADHD over the course of 12 months of robust treatment with extended-release methylphenidate. Rigorous, monitored stimulant treatment may be associated with objectively determined cognitive benefits; however, practice effects in this open trial cannot be ruled out. Further study on this important topic is warranted.     

Parity,Intransitivity, And A Context-Sensitive Degree Analysis of Gradability

Larry Temkin challenged what seems to be an analytic truth about comparatives: if A is Φ-er than B and B is Φ-er than C, then, A is Φ-er than C. Ruth Chang denies a related claim: if A is Φ-er than B and C is not Φ-er than B, but is Φ to a certain degree, then A is Φ-er than C. In this paper I advance a context-sensitive semantics of gradability according to which the data uncovered by Temkin and Chang leave both statements intact.
