Brain drawings following traumatic brain injury (TBI) and links to illness perceptions and health outcomes – Findings from a population-based study

Objective: Individuals’ illness perceptions predict health behaviours and influence functional outcomes. This study examined associations between a novel assessment of illness perceptions, in the form of adult’s brain drawings after traumatic brain injury (TBI) and questionnaire measures of illness perceptions, quality of life and post-concussive symptoms.

Design: Population-based, prospective longitudinal study examining 245 adults with predominantly mild TBI with high risk of complications.

Main outcome measures: Participants were asked to draw pictures of what they thought their brain looked like before injury and at baseline and one month post-injury. Drawing characteristics (height, width and percentage damage at one month) were examined in relation to each outcome of interest at six months.

Results: Greater damage at one month was associated with more negative illness perceptions (rs = .23), poorer mental health (rs = ?.21), and more total post-concussive symptoms (rs = .27 to r = .35) at six months. The extent of damage depicted reduced over time (p < .001). No associations were found between the amount of damage drawn and injury severity, nor the height or width of drawings and injury severity or illness perceptions.

Conclusion: Drawings post-TBI offer a simple, cost- and time-effective way to begin discussions and improve understanding of peoples’ illness perceptions.     

A connectionist implementation of the theory of planned behavior: association of beliefs with exercise intention.

The theory of planned behavior suggests attitudes are a product of salient beliefs. This study examined whether aggregating salient beliefs was plausible within a more biologically centered information-processing environment. A neural network was used to examine associations among beliefs relating to exercise intention. Data on intentions and behavioral, normative, and control beliefs from 114 respondents were used to train (by error backpropagation) a neural network to associate beliefs with intention. The R-sup-2 between the network's estimated and self-reported intention was.66. The network's representation comprised 6 belief profiles associated with high, moderate, or low behavioral intention. The neural network accommodated complex relationships among beliefs and belief-intention associations and indicated how high-level constructs such as attitudes may be viewed as the best fit (compromise state) between aroused beliefs.     

Dimensions of On-the-Job Learning Styles

The aim of this study is to identify dimensions of on‐the‐job learning styles that can create an awareness among employees and offer them opportunities for the improvement of their on‐the‐job learning. In order to be able to select relevant dimensions, we propose four criteria: dimensions should: (a) concern activities and behaviour; (b) be changeable by learners; (c) be applicable to the workplace context; and (d) be uni‐dimensional. After reviewing the literature in light of these criteria, we conclude that employees need to be aware of four core dimensions of on‐the‐job learning styles: (a) whether they are reproductive or developmental learners; (b) whether they tend to learn alone, from others, or with others; (c) whether they are holistic or analytical learners; and (d) how they engage in reflection (e.g. the depth of reflection). Le but de cette étude est d’identifier les dimensions composant des styles d’apprentissage sur le tas et plus particulièrement la création d’une conscience parmi les salariés et l’opportunité d’accroître les possibilités d’apprentissage sur le tas. Afin de sélectionner des dimensions appropriées, nous proposons 4 critères: les dimensions doivent a) concerner des activités et le comportement, b) être variables selon les apprenants, c) être applicable dans un contexte de travail et d) être uni‐dimensionnel. Une revue de la littérature à la lumière de ces critères montre que les salariés ont besoin d’être conscients de 4 dimensions fondamentales des styles d’apprentissage sur le tas: a) Sont‐ils des apprenants “passifs” ou “actifs” ? b) Tendent‐ils à apprendre seul, avec d’autres ou d’autres personnes ? c) Sont‐ils des apprenants holistiques ou analytiques ? et d) Quelle est la façon dont ils s’engagent dans une réflexion (e.g. la profondeur de la réflexion)?     

Adaptation in conflict: are conflict-triggered control adjustments protected in the presence of motivational distractors?

Solving a conflict between two response options in an interference task has been found to increase control in a subsequent conflict situation. The present research examined whether such conflict adaptation persists in the presence of distractors that have motivational relevance and are therefore competing for attentional resources (i.e. they signal opportunities for monetary gains or losses contingent on overall task performance). In an adjusted flanker task, motivational (versus neutral versus no) distractors were presented together with the current trial while the previous trial never included any distractor. Accumulated evidence across three studies showed that motivational distractors reduced the conflict adaptation effect. This was found irrespective of the location at which the distractor occurred (Study 1), and independent of its valence (i.e. reward or loss, Study 2). Study 3 and a merged data analysis ruled out low-level alternative explanations. In line with a dual competition account (Pessoa, L. (2009). How do emotion and motivation direct executive control? Trends in Cognitive Sciences, 13(4), 160–166. doi:10.1016/j.tics.2009.01.006), our results show that conflict adaptation is not fully protected in the presence of motivational distractors. We discuss whether this should be interpreted as a limitation, or as reflecting the flexibility of the control system in dealing with motivationally relevant information.     

Teachers as informants: countering extremism and promoting violence

ABSTRACT

This article is a response to Muslim students reporting that they had been silenced by fear of the PREVENT Counter-Terrorism Strategy. By adopting a Critical Realist stance, real generative mechanisms of this actual phenomenon are investigated and theorised. Recognition of changing definitions of both ‘radicalisation’ and ‘extremism’ in different versions of PREVENT results in the discursive aspect of these real generative mechanisms being investigated using critical discourse analysis (CDA). This analysis identifies the emergence of a violent discourse of ‘radicalisation’ and ‘extremism’ (RadEx) that it is theorised has the capacity to promote rather than prevent violence. Finally, a process by which this production of violence in the classroom might have been avoided is explored and this indicates that critique of government efforts to counter ‘radicalisation’ and ‘extremism’ is a vital aspect of pedagogy in the context of PREVENT and the War on Terror.     

Real-life revenge may not effectively deter norm violations

ABSTRACT

The current article examined the characteristics of real-life revenge acts. A demographically diverse sample of avengers described autobiographical revenge acts and the preceding offense. They rated the severity of both acts, the time before taking revenge, and motives for the timing. Independent raters also rated the severity of both acts and coded the domains. Results revealed that real-life revenge is (1) by and large equally common as revealed by lab-based studies on revenge, but (2) is usually a delayed response, and (3) although similar to offenses in severity (according to independent parties), it is dissimilar in the domain. These characteristics contradict manifestations of revenge as studied in lab research (e.g., as a response that must take place immediately and in the same domain). These discrepancies suggest that not all real-life instances of revenge are optimally suited to serve a deterrence function and that other motives may underlie more destructive revenge acts.
