Motor imagery ability and internal representation of movement in children with probable developmental coordination disorder

It has been hypothesised that deficits in the functioning of the mirror neuron system (MNS) and internal modelling may contribute to the motor impairments associated with DCD. These processes can be explored behaviourally through motor imagery paradigms. Motor imagery proficiency of children with and without probable DCD (pDCD) was examined using a complex hand rotation task to explore whether motor imagery strategies could be used during more complex tasks. Forty-four boys aged 7–13 years participated, 22 with pDCD (mean = 9.90 years ± 1.57) and 22 controls (mean = 9.68 years ± 1.53). Participants completed the task twice: with and without motor imagery instructions. Stimuli were presented in two rotational axes – palm/back, and eight 45° rotational steps. Both groups showed evidence of following the biomechanical and postural constraints of actual movements. Responses of children with pDCD were slower and less accurate than controls, with group differences increasing alongside task complexity. A greater impact of biomechanical constraints for accuracy was observed in the DCD group. The response characteristics of children with pDCD likely reflects a reduced capacity to mentally manipulate a body schema and reduced visuo-motor processing capabilities. Behaviourally, these processes are linked to MNS and internal modelling function, suggesting deficits in these systems may contribute to the movement difficulties characteristic of DCD.     

Augmenting Visual Search Performance With Transcranial Direct Current Stimulation (tDCS)

Military personnel endure rigorous and demanding man-hours designated to monitoring and locating targets in tasks such as cyber defense and Unmanned Aerial Vehicle (UAV) operators. These tasks are monotonous and repetitive, which can result in vigilance decrement. The objective of the study was to implement a form of noninvasive brain stimulation known as transcranial DC stimulation (tDCS) over the left frontal eye field (LFEF) region of the scalp to improve cognitive performance. The participants received anodal and cathodal stimulation of 2 mA for 30 min as well as placebo stimulation on 3 separate days while performing the task. The findings suggest that anodal and cathodal stimulation significantly improves detection accuracy. Also, a correlation was detected between percent of eye closure (PERCLOS) and blinking frequency in relation to stimulation condition. Our data suggest that tDCS over the LFEF would be a beneficial countermeasure to mitigate the vigilance decrement and improve visual search performance.     

The triumph of American psychiatry: How it created the modern therapeutic state

Over the past 170 years, American psychiatry has progressively asserted its authority over a larger segment of the American population. From the mid-1800s to the end of World War II, psychiatry had authority over the asylum population, which markedly increased in the first half of the twentieth century due to the influence of eugenics, an ideology that argued the ‘mentally ill’ had to be segregated from society. After the war, American psychiatry adopted Freudian conceptions of mental disorders, which enabled it to begin treating people in the community who were ‘neurotic’ in some way, which dramatically expanded its influence in society. Then, in the 1970s, when many in American society were questioning psychiatry’s legitimacy as a branch of medicine, the American Psychiatric Association (APA) responded by adopting a disease model for diagnosing mental disorders, which it set forth in the third edition of its Diagnostic and Statistical Manual. There were no scientific discoveries that led to this new model, but soon the APA was informing the American public that mental disorders were diseases of the brain, and that psychiatric drugs helped fix those diseases, ‘like insulin for diabetes.’ The APA, in concert with pharmaceutical companies, has successfully exported this belief system to much of the developed world. In order to break free of this ‘therapeutic state,’ the public needs to understand the history of how it came to be, and see the social injury it has caused.     

Teaching religious education as a second choice. The case of three male student teachers in Finland

This article explores the professional reflection of three male religious education (RE) student teachers during their one-year pedagogical training. The participants (n = 3) interviewed in this article were chosen on the basis of their self-report in the questionnaire in which they claimed no previous teaching experience. The participants were interviewed three times: at the beginning, in the middle and at the end of their one-year teacher education. The interviews were analysed with qualitative content analysis. The study showed some patterns in the student teachers reflections concerning developmental aims, professionalism, and convictions during the year. The article concludes that in RE teacher education developing pedagogical thinking should be accompanied with becoming aware of the role of personal life history and contextual situation play in the process of becoming a sound professional in RE.     

Temporality and the torments of time

Immersion in time gives birth to consciousness, as well as conflict and torment. When human beings developed a sense of future, they also gained the ability to anticipate threats from nature or their fellow beings. They thereby created cultures that are bastions of survival, as well as places of poetry, art and religion where they could band together and reflect upon their common plight. The practice of psychoanalysis is in many ways a temporal process, a process of remembering, for owning and elaborating a past that gives us substance, thereby providing a basis for reflective consciousness. Stimulated by Freud's early writings, Lacan, Laplanche and their successors in particular have focussed extensively on time and psychoanalysis, and their views are a central point of this discussion. A substantial case study is offered that provides concrete examples of these perspectives. A multi‐faceted view of temporality emerges, one that is more syncopated than linear or teleological. In conclusion, I will briefly discuss recent findings in the neuroscience of memory and ‘time travel’ that underpin contemporary psychoanalytic ideas in surprising ways. It is important to remember that acceptance of the contradictory nature of temporal experience can open space for increased freedom and playfulness.     

Exercise can improve physical self perceptions in adolescents with low motor competence

Adolescents with low motor competence have diminished perceptions of their physical self and tend to avoid physical activities. This study examined the outcomes of an exercise intervention that focused on improving aerobic fitness, strength, and self-perceptions in the physical domain in adolescents with poor motor coordination. The sample included 35 adolescents with low motor competence, comprising boys (n = 25) and girls (n = 10) ranging in age from 13 to 17 years, who attended two sessions per week in the 13 week exercise intervention study (AMP it up). Physical self-perceptions were measured before and after the intervention using the Physical Self Perception Profile and Perceived Importance Profile. Significant improvements in perceived Physical Condition, Attractive Body and Physical Strength sub domain scores were identified between pre and post-test. Adjusting for age, gender, BMI and attendance, regression analyses revealed that Attractive Body was the strongest predictor of Physical Self Worth at pre-test, joined by Physical Condition at post-test. This exercise intervention had a positive impact on adolescent physical self-perceptions, in particular males, with improvements in those sub domains specifically related to the exercise program. Changes in specific aspects of Physical Self Worth can be facilitated by exercise interventions, after a relatively short period of time, in adolescents with poor motor coordination.     

Naturalistic outcome of case formulation-driven cognitive-behavior therapy for anxious depressed outpatients

This article describes a case formulation-driven approach to the treatment of anxious depressed outpatients and presents naturalistic outcome data evaluating its effectiveness. Fifty-eight patients who received case formulation-driven cognitive-behavior therapy (CBT) in a private practice setting were studied. All received individual CBT guided by a case formulation and weekly outcome monitoring; in addition, 40 patients received adjunct therapies, including pharmacotherapy, which were added as indicated by the case formulation and the results of weekly outcome monitoring. Patients treated with case formulation-driven CBT showed statistically and clinically significant changes in anxiety and depression that were generally comparable to those reported in published randomized controlled trials of empirically supported therapies (ESTs) for single mood and anxiety disorders. Findings support the proposal that anxious depressed patients who have multiple comorbidities and require multiple therapies can benefit from empirically supported treatments guided by a case formulation and weekly outcome monitoring.     

Agreement and movement: a syntactic analysis of attraction

This paper links experimental psycholinguistics and theoretical syntax in the study of subject-verb agreement. Three experiments of elicited spoken production making use of specific characteristics of Italian and French are presented. They manipulate and examine its impact on the occurrence of 'attraction' errors (i.e. incorrect agreement with a word that is not the subject of the sentence). Experiment 1 (in Italian) shows that subject modifiers do not trigger attraction errors in free inverted VS (Verb Subject) structures, although attraction was found in VS interrogatives in English (Vigliocco, G., & Nicol, J. (1998). Separating hierarchical relations and word order in language production. Is proximity concord syntactic or linear? Cognition, 13-29) In Experiment 2 (in French), we report stronger attraction with preverbal clitic object pronouns than with subject modifiers. Experiment 3 (in French) shows that displaced direct objects in the cleft construction trigger attraction effects, in spite of the fact that the object does not intervene between the subject and the verb in the surface word order (OSV). Moreover, attraction is stronger in structures with subject-verb inversion (...). These observations are shown to be naturally interpretable through the tools of formal syntax, as elaborated within the Principles and Parameters/Minimalist tradition. Three important constructs are discussed: (1) the hierarchical representation of the sentence during syntactic construction, and the role of intermediate positions by which words transit when they move; (2) the role of specific hierarchical (c-command) but also linear (precedence) relations; and (3) the possibility that agreement involves two functionally distinct components. A gradient of computational complexity in agreement is presented which relates empirical evidence to these theoretical constructs.
