Division of Labor: Procedural Learning in Teacher-led Small Groups

This article presents an observational study of teacher-student interaction in fourth-grade small group sessions introducing an algorithm for solving remainder divisions. The groups are segregated by arithmetic achievement. Teacher and student input is analyzed with reference to a cognitive analysis of the task. A quantitative analysis compares amounts of teacher and student input at specific, cognitively significant points in procedures across groups. This analysis shows that there are qualitative differences both in solution strategies that evolve in the course of the lesson and in the extent to which the teacher-student interaction focuses on two "critical constraints" that are central to acquisition of this procedure. A subsequent analysis of transcribed protocols from the small group sessions discloses interactional mechanisms that can account for these differences. Much of the teacher's input is characterized as an unpacking of the necessary procedure by calling in subprocedures which take the students' responses as arguments and by specifying subprocedures lower down in the goal hierarchy when students failed to produce adequate responses. The interactive mechanisms combine with students' background knowledge to result in the group differences detected in the quantitative analysis.     

Personality and Cognitive Ability as Predictors of Typical and Maximum Managerial Performance

Despite long-established distinctions between typical and maximum performance variables on both the predictor and criterion side, little previous research has directly addressed the extent to which these distinctions translate into differential predictor-criterion relationships. Using a sample of candidates for managerial positions, we examined relations of predictors conceptually linked to typical (i.e., broad, narrow, and compound personality traits) and maximum (i.e., broad and narrow cognitive abilities) performance with corresponding criterion measures (N = 84–873). Supervisory ratings of managerial performance served as the typical performance criterion, whereas maximum performance was assessed via an assessment center. Confirmatory factor analyses supported the distinction between typical and maximum performance. Results also confirmed our hypothesis that cognitive abilities are more strongly correlated with maximum performance than with typical performance and largely supported the expectation of the opposite pattern with personality traits as predictors.     

Military Influence Tactics: Lessons Learned in Iraq and Afghanistan

When deployed U.S. soldiers attempt to influence the attitudes, beliefs, or behaviors of civilians, success can save lives and failure can be deadly. Survey data from 228 military personnel with deployment experience to Iraq and Afghanistan revealed that in a challenging wartime environment, empathy, respect, prior relationships, and familiarity with influence targets predicted success in cross-cultural influence attempts. Influence techniques involving resources and positive feelings were used more commonly in relatively successful influence attempts; negative tactics were used more commonly in unsuccessful attempts.     

The Perceptions of Terminated Ministers Scale—Revised

The Perceptions of Terminated Ministers Scale—Revised (PTM-R), a 15-item measure of perceptions of termination appropriate to members of clergy, was developed for use among researchers studying how clergypersons perceive the effects of forced termination events. To examine the reliability and validity of the measure, three samples of clergy were assessed using the PTM and PTM-R. The three samples used Barfoot et al.’s (2005) working definition of forced pastoral exits. Their definition does not distinguish between being fired or forced to resign. Each participant was asked to specify whether they were fired or forced to resign. Recently, Tanner et al. (2012) offered a new definition of forced termination: “Forced termination is the result of a process of involuntary removal of paid and non-paid clergy-persons that results from a period of traumatic and demeaning psychological and emotional abuse” (p. 14). Data analysis among all three samples supports the reliability and validity of the scale and commends it for further use among clergy who have experienced forced termination.     

On his brother's blindness

This commentary is slightly different from previous ones in that the clinical work presented took place some 20 years ago. This gave an opportunity, for those commentators who wished to, to take up how they think the work of a child psychotherapist might have changed in the intervening years.     

Processing ordinality and quantity: ERP evidence of separate mechanisms

We report an event-related potential (ERP) experiment of ordinal processing exploring the relationship between ordinal and numerical information.     

Deeper attentional masking by lateral objects in children with autism

Autism spectrum disorder (ASD) is often associated with a detail-oriented perception and overselective attention in visual tasks, such as visual search and crowding. These results were obtained manipulating exclusively the spatial properties of the stimuli: few is known about the spatio-temporal dynamics of visual processing in ASD. In this study we employed an attentional masking (AM) paradigm comparing children with ASD and IQ-matched typically developing (TD) controls. The AM effect refers to an impaired identification of a target followed by a competitive masking object at different proximities in space and time. We found that ASD and TD groups did not differ in the AM effect provoked by the competitive object displayed in the same position of the target. In contrast, children with ASD showed a deeper and prolonged interference than the TD group when the masking object was displayed in the lateral position. These psychophysical results suggest that the inefficient attentional selection in ASD depends on the spatio-temporal interaction between competitive visual objects. These evidence are discussed in the light of the ASD altered neural connectivity hypothesis and the reentrant theory of perception.     

Do behavioural self-blame and stigma predict positive health changes in survivors of lung or head and neck cancers?

Survivors of lung or head and neck cancers often change tobacco and alcohol consumption after diagnosis, but few studies have examined other positive health changes (PHCs) or their determinants in these groups. The present study aims to: (a) document PHCs in survivors of lung (n?=?107) or head and neck cancers (n?=?99) and (b) examine behavioural self-blame and stigma as determinants of PHCs. We hypothesised that: (a) survivors would make a variety of PHCs; (b) behavioural self-blame for the disease would positively predict making PHCs; and (c) stigma would negatively predict making PHCs.

Methods: Respondents self-administered measures of PHC, behavioural self-blame, and stigma. Hierarchical multiple regression analysis tested the hypotheses.

Results: More than 65% of respondents reported making PHCs, the most common being changes in diet (25%), exercise (23%) and tobacco consumption (16.5%). Behavioural self-blame significantly predicted PHCs but stigma did not. However, both behavioural self-blame and stigma significantly predicted changes in tobacco consumption.

Conclusions: Many survivors of lung or head and neck cancers engage in PHCs, but those who do not attribute the disease to their behaviour are less likely to do so. Attention to this problem and additional counselling may help people to adopt PHCs.     

Two sides of the same coin? On the history and phenomenology of chronic fatigue and burnout

Background: Burnout and chronic fatigue syndrome (CFS) are two fatigue syndromes which have developed largely independently from each other, yet whose similarities in symptoms can be a source of confusion. We aim to explore the phenomenology of burnout and CFS in a historical context as this may provide some insight into the links and relationship between these conditions. Method: A narrative review based on literature in the fields of history, social science and medicine. Results: The origins of CFS lie within medicine, whereas burnout developed in a psychological setting. As well as symptoms, burnout and CFS also share similar themes such as an overload process triggering illness onset, the need for restoration of depleted energy, external causal attributions and the characteristics of people suffering from these illnesses. However, these themes are expressed in either psychological or medical terms according to the historical background. Conclusion: Despite their similarities, there have been few direct comparisons of the two concepts. Culture, illness perceptions and accountability are important issues in both conditions and could contribute to their differences. Comparing burnout and CFS within one sample frame, thus looking beyond the psychology/medicine divide, could be a useful first step towards understanding their relationship.     

exploring drug users' illness representations of hiv,hepatitis b and hepatitis c using repertory grids

Abstract

Hepatitis B and C viruses are more prevalent among injecting drug users than HIV. This study explored drug users' illness representations of hepatitis B and C using repertory grid methodology. Initially, nine drug users were presented with six elements including hepatitis B and C, and HIV. Constructs were elicited via the sequential form variation of the method of triads. Elements were rated on elicited constructs using a five-point scale, and analyzed using “Flexigrid”. In a second quantitative research stage, 52 drug users were presented with six elements and supplied constructs. Results of the first stage indicated participants were able to generate constructs relating to Leventhal et al.'s (1980) features of illness representations. Most constructs, however, were causal in nature. Participants perceived hepatitis B, C and HIV similarly along the causal component. This similarity on the causal component was largely replicated in the second research stage. Participants, however, distinguished HIV from hepatitis B and C along serious, cure and timeline features. Participants did not distinguish hepatitis B from hepatitis C. The implications of these results for health promotion are discussed.
