Ergonomie cognitive d’un conseil génétique pour le test présymptomatique de maladie de Huntington

We would like to propose the analysis of a multidisciplinary genetic counselling activity. More precisely, we study an interaction that took place in the consultation between an asymptomatic patient who requests for a predictive genetic testing of Huntington’s disease and two doctors successively. We describe the failure of the multidisciplinary team’s attempt to influence the conviction, or the personal rationality, of the patient for the genetic risk perception. More generally, this study illustrates the communication practices which are engendered by modern medicine can be very delicate. Therefore, this information is carried by the act of informing. This action is made of processes which are relatively independent.     

Hume and the enactive approach to mind

An important part of David Hume’s work is his attempt to put the natural sciences on a firmer foundation by introducing the scientific method into the study of human nature. This investigation resulted in a novel understanding of the mind, which in turn informed Hume’s critical evaluation of the scope and limits of the scientific method as such. However, while these latter reflections continue to influence today’s philosophy of science, his theory of mind is nowadays mainly of interest in terms of philosophical scholarship. This paper aims to show that, even though Hume’s recognition in the cognitive sciences has so far been limited, there is an opportunity to reevaluate his work in the context of more recent scientific developments. In particular, it is argued that we can gain a better understanding of his overall philosophy by tracing the ongoing establishment of the enactive approach. In return, this novel interpretation of Hume’s ‘science of man’ is used as the basis for a consideration of the current and future status of the cognitive sciences.

Core self-evaluations interact with cognitive ability to predict academic achievement

Extant research suggests that core self-evaluations (CSE) is associated with various work-related criteria, but such research often focuses on main effects when predicting subjective outcomes. Drawing upon psychological theories involving self-concept and motivation, we investigated both the main and interactive effects of CSE and cognitive ability when predicting an objective outcome. Specifically, results indicated that high CSE strengthened the positive relation between cognitive ability and academic achievement. Study contributions and limitations are discussed.     

Psychotherapeutic practitioners’ views of the efficacy of mindfulness for the treatment of obsessive compulsive disorder: A qualitative key informant analysis

Objectives: A substantial proportion of individuals affected by obsessive compulsive disorder (OCD) are not experiencing adequate therapeutic outcomes from current standard psychotherapeutic treatments. Mindfulness has had a positive therapeutic impact on many symptoms associated with OCD. This study investigated the views of experienced psychotherapeutic practitioners concerning the potential efficacy of mindfulness as a therapeutic intervention for individuals with OCD.

Method: Six psychotherapeutic professionals experienced in using mindfulness with individuals affected by OCD were interviewed. Data were subjected to thematic analysis.

Results: Participants reported that engaging in mindfulness enabled people with OCD to experience an altered relationship with their symptoms and self. This new attitude, in conjunction with cognitive behavioural therapy, was perceived as helping individuals manage their OCD in an effective and healthy way. However, participants were unsure whether an exclusively mindfulness-based treatment would be effective.

Conclusion: This study indicates the potential for mindfulness practice to constitute a valuable therapeutic resource in helping people manage their OCD experience. Implications for future research and practice are considered.     

Interruption of phonological coding in conduction aphasia

A case study of conduction aphasia, investigating single word repetition, phonological coding, and short-term memory, is reported. Evidence from intact adults suggests that repetition can occur through either a lexical route or a direct auditory-articulatory link. For this conduction aphasic, E.A., the direct link was impaired, although the lexical route could be used to produce accurate single word repetition. Several experiments demonstrated a significant impairment in the generation and maintenance of an abstract phonological code. The consequences of a disruption of phonological coding on speech perception and on verbal short-term memory are discussed.     

Fake feedback on pain tolerance impacts proactive versus reactive control strategies

It is well-known that beliefs about one’s own ability to execute a task influence task performance. Here, we tested the hypothesis that beliefs about a specific self-control capacity, namely pain tolerance, modulate basic cognitive control processes. Participants received fake comparative social feedback that their ability to tolerate painful stimulations was either very poor or outstanding after which they performed an unrelated go/no-go task. Participants receiving low-tolerance feedback, relative to high-tolerance feedback, were less successful at inhibiting their responses and more influenced by previous trial conditions, as indicated by an increased slowdown following errors and more failed inhibitions following go-trials. These observations demonstrate a shift from a more proactive to a more reactive control mode. This study shows that providing feedback about one’s own capacity to control impulsive reactions to painful stimulations directly influences low-level cognitive control dynamics.     

Children and Politics: An Empirical Reassessment of Early Political Socialization

Demands for the inclusion of children, the youngest citizens, in democratic decision making are increasing. Although there is an abundance of empirical research on the political orientations of adolescents, there is a paucity of research on younger children's orientations. Our panel study of more than 700 children in their first year of primary school shows that these young children already exhibit consistent, structured political orientations. We examine the distribution and development of political knowledge, issue orientations, and notions of good citizenship. We find achievement differences between subgroups at the beginning of the school year, and these differences do not disappear. Children from ethnic minorities and lower socioeconomic residence areas show relatively less developed political orientations, and they do not improve as much over the school year as other children. Furthermore, normative political orientations and cognitive orientations differ in their development.     

Individual differences in spatial relation processing: effects of strategy, ability, and gender

Numerous studies have focused on the distinction between categorical and coordinate spatial relations. Categorical relations are propositional and abstract, and often related to a left hemisphere advantage. Coordinate relations specify the metric information of the relative locations of objects, and can be linked to right hemisphere processing. Yet, not all studies have reported such a clear double dissociation; in particular the categorical left hemisphere advantage is not always reported. In the current study we investigated whether verbal and spatial strategies, verbal and spatial cognitive abilities, and gender could account for the discrepancies observed in hemispheric lateralization of spatial relations. Seventy-five participants performed two visual half field, match-to-sample tasks (Van der Ham, van Wezel, Oleksiak, & Postma, 2007; Van der Ham, Raemaekers, van Wezel, Oleksiak, and Postma, 2009) to study the lateralization of categorical and coordinate relation processing. For each participant we determined the strategy they used in each of the two tasks. Consistent with previous findings, we found an overall categorical left hemisphere advantage and coordinate right hemisphere advantage. The lateralization pattern was affected selectively by the degree to which participants used a spatial strategy and by none of the other variables (i.e., verbal strategy, cognitive abilities, and gender). Critically, the categorical left hemisphere advantage was observed only for participants that relied strongly on a spatial strategy. This result is another piece of evidence that categorical spatial relation processing relies on spatial and not verbal processes.     

Is anxiety about health associated with desire to exercise, physical activity, and exercise dependence?

There are significant gaps in the literature regarding the behavioural consequences of health anxiety. Although past research indicates that health anxiety is associated with distinctive maladaptive behaviours, such as reassurance seeking, the relationship between health anxiety and wellness-related behaviours, such as physical activity, has not been adequately examined. Given that health anxiety is associated with excessive attempts to ensure health and avoid illness, health anxiety could be potentially related to extreme physical activity, known as exercise dependence. Using the cognitive behavioural model of health anxiety as a framework, this exploratory study investigated the relationships between health anxiety, exercise desire, physical activity, and exercise dependence.Undergraduate university students (n = 144) completed a battery of online measures. Results indicated that only the perceptual component of health anxiety, namely hypervigilance to somatic symptoms, was related to exercise desire and components of exercise dependence. Implications of the findings are discussed and future research avenues are explored.     

Age effects on different components of theory of mind

The effects of aging on the cognitive and affective dimensions of theory of mind (ToM), and on the latter’s links with other cognitive processes, such as information processing speed, executive functions and episodic memory, are still unclear. We therefore investigated these effects in young (n = 25), middle-aged (n = 20) and older adults (n = 25), using separate subjective and objective assessment tasks. Furthermore, a novel composite task probed participants’ abilities to infer both cognitive and affective mental states in an interpersonal context. Although age affected the objective ToM tests, results revealed a direct aging effect on the second-order ToM, but an indirect one on the first-order cognitive ToM, mediated mainly by age-related declines in executive functions. This study supports the notion of an age-related distinction between subjective and objective assessments of ToM, and confirms that ToM is a complex mental ability with several characteristics reliant to some extent on executive processes.
