Absorbed in thought: the effect of mind wandering on the processing of relevant and irrelevant events

This study used event-related potentials to explore whether mind wandering (task-unrelated thought, or TUT) emerges through general problems in distraction, deficits of task-relevant processing (the executive-function view), or a general reduction in attention to external events regardless of their relevance (the decoupling hypothesis). Twenty-five participants performed a visual oddball task, in which they were required to differentiate between a rare target stimulus (to measure task-relevant processes), a rare novel stimulus (to measure distractor processing), and a frequent nontarget stimulus. TUT was measured immediately following task performance using a validated retrospective measure. High levels of TUT were associated with a reduction in cortical processing of task-relevant events and distractor stimuli. These data contradict the suggestion that mind wandering is associated with distraction problems or specific deficits in task-relevant processes. Instead, the data are consistent with the decoupling hypothesis: that TUT dampens the processing of sensory information irrespective of that information's task relevance.     

New Caledonian crows use tools for non-foraging activities

Tool use is of great interest for cognitive research, largely because it can be particularly revealing about the underlying information processing mechanisms. Tool use that is inflexible or requires extensive experience to change, and that is only addressed towards specific targets such as food, is not likely to reflect unusual or particularly complex cognition. On the contrary, if tools are employed flexibly and for a variety of innovative purposes, then conventional combinations of inherited predispositions and associative learning are challenged and interesting questions emerge. Since New Caledonian crows (Corvus moneduloides) are especially adept at using and making tools for food extraction, we decided to examine their ability to generalise this to other contexts. We recorded how five pairs of New Caledonian crows interacted with novel objects that were not associated with food. We observed eight occasions in which the first contact with the novel object was mediated by a tool, suggesting that the function of the tool was for exploration. This is the first report of non-foraging tool use in New Caledonian crows, and it implies that the cognitive operations controlling tool-oriented behaviour in this species are more general than previously thought.     

What is the deficit in phonological processing deficits: auditory sensitivity, masking, or category formation?

Although children with language impairments, including those associated with reading, usually demonstrate deficits in phonological processing, there is minimal agreement as to the source of those deficits. This study examined two problems hypothesized to be possible sources: either poor auditory sensitivity to speech-relevant acoustic properties, mainly formant transitions, or enhanced masking of those properties. Adults and 8-year-olds with and without phonological processing deficits (PPD) participated. Children with PPD demonstrated weaker abilities than children with typical language development (TLD) in reading, sentence recall, and phonological awareness. Dependent measures were word recognition, discrimination of spectral glides, and phonetic judgments based on spectral and temporal cues. All tasks were conducted in quiet and in noise. Children with PPD showed neither poorer auditory sensitivity nor greater masking than adults and children with TLD, but they did demonstrate an unanticipated deficit in category formation for nonspeech sounds. These results suggest that these children may have an underlying deficit in perceptually organizing sensory information to form coherent categories.     

Group‐based evaluations for pupil‐on‐teacher violence: The impact of teacher intervention strategy

Although extreme violence to teachers is rare, the fact remains that in the UK, 29% of teachers report having been physically assaulted by a pupil (ATL, 2008a ). The ways in which responsibility for such assaults are attributed can have legal, educational and managerial implications. In the current study, teachers (N = 66), pupils (N = 68) and parents (N = 64) from a large secondary school in the UK read an incident report form outlining an incident depicting a pupil physically assaulting a teacher. The incident report was manipulated such that, prior to being assaulted, the teacher had either separated the assailant pupil from another pupil using a physical or non‐physical intervention. Results revealed that participating parents' and teachers' evaluations of the assailant's parents and the teacher differed from those of pupils in several ways. The results are discussed in terms of group‐based responsibility for deviant behaviour and implications for teacher behaviour in response to pupil on teacher violence.

Peer-facilitated cognitive dissonance versus healthy weight eating disorders prevention: A randomized comparison

Research supports the efficacy of both cognitive dissonance (CD) and healthy weight (HW) eating disorders prevention, and indicates that CD can be delivered by peer-facilitators, which facilitates dissemination. This study investigated if peer-facilitators can deliver HW when it is modified for their use and extended follow-up of peer-facilitated CD as compared to previous trials. Based on pilot data, we modified HW (MHW) to facilitate peer delivery, elaborate benefits of the healthy-ideal, and place greater emphasis on consuming nutrient dense foods. Female sorority members (N = 106) were randomized to either two 2-h sessions of CD or MHW. Participants completed assessment pre- and post-intervention, and at 8-week, 8-month, and 14-month follow-up. Consistent with hypotheses, CD decreased negative affect, thin-ideal internalization, and bulimic pathology to a greater degree post-intervention. Both CD and MHW reduced negative affect, internalization, body dissatisfaction, dietary restraint, and bulimic pathology at 14 months.     

Burnout predictors among prison officers: The moderating effect of temperamental endurance

The study investigates whether work stressors, coping styles, and work-related social support predict burnout among prison officers (N = 476). It was hypothesized that coping and social support would mediate the effects of work stressors on burnout and that these effects would be moderated by temperamental endurance. Results of structural equation modeling showed that emotion-oriented coping was positively related to emotional exhaustion, and negatively to personal accomplishment. Task-oriented coping was positively related to personal accomplishment. Social support from work was negatively related to emotional exhaustion. The effects of work stressors on burnout were mediated by work-related social support and by emotion-oriented coping. Additionally, some of these mediating effects were moderated by endurance. Work-related social support was negatively related to depersonalization only among participants with strong endurance. High level of work stressors predicted high emotion-oriented coping only among individuals with weak endurance.     

Putting Values into Practice: Public Policy and the Future of Mental Health Consumer-run Organizations

The purpose of the paper is to reflect on value dilemmas in mental health consumer-run organizations and to discuss implications for research, policy, and practice. We review the roots of consumer-run organizations in the self-help movement and the psychiatric survivor liberation movement, focusing on the distinctive values espoused by consumer-run organizations. We also discuss evidence-based and value-based approaches to mental health policy formulation and mental health reform, noting the particular importance of value-based approaches and the role that consumer-run organizations can play in mental health reform. Based on our experiences conducting a participatory action research study of four mental health consumer-run organizations, we identify and examine several value dilemmas, discuss the lessons that we learned about these value dilemmas, and note their implications for future directions in research, policy, and practice.     

A comparative study of adolescent risk assessment instruments: predictive and incremental validity

Promising new adolescent risk assessment tools are being incorporated into clinical practice but currently possess limited evidence of predictive validity regarding their individual and/or combined use in risk assessments. The current study compares three structured adolescent risk instruments, Youth Level of Service/Case Management Inventory (YLS/CMI), Structured Assessment of Violence Risk in Youth (SAVRY), and Psychopathy Checklist: Youth Version (PCL:YV), for both predictive and incremental validity with respect to general and violent recidivism. Receiver operating characteristic and hierarchical logistic regression analyses revealed that the risk tools predicted general and violent recidivism to varying degrees of accuracy, but the SAVRY offered the most in incremental validity. Clinical implications and future directions for youth risk assessment are discussed.     

Why do people with an anxiety disorder utilize more nonmental health care than those without?

OBJECTIVE: It is unclear why nonmental healthcare utilization is greater among those with psychological problems. The authors examined healthcare utilization in HMO patients to determine whether greater utilization in anxiety disorder (AD) patients was explained by anxiety symptoms (increasing sensitivity to physical symptoms) or comorbid illness (causing greater need for services). DESIGN: Patients were randomly selected from the database of a multi-specialty practice and 1,041 completed a survey assessing psychological symptoms, health behaviors, and demographics. Anxiety symptoms were assessed by questionnaire and the presence of an AD was determined from the medical chart. Healthcare encounters and medication use were abstracted from medical charts and HMO claims data. MAIN OUTCOME MEASURES: Healthcare utilization. RESULTS: Both AD and anxiety symptoms predicted utilization, but symptoms were not associated with utilization in a model that also included AD. Comorbid illness was significantly associated with utilization independent of AD and somewhat reduced the strength of the AD-utilization association. The results were replicated in comparison of those with any psychiatric disorder to those without. CONCLUSION: Among those with AD, greater utilization is not explained by anxiety symptoms but is partly explained by greater comorbid illness. Further study is needed to understand excess healthcare utilization among AD patients.
