Social competence following mild head injury and moderate traumatic brain injury: Investigating the neuropsychological relationships between arousal, social decision-making and depression

Client-directed long-term rehabilitative goals and life satisfaction following head injury emphasize the importance of social inclusion, rather than cognitive or physical, outcomes. However, very little research has explored the socio-emotional factors that pose as barriers to social reintegration following injury. This study investigates social barriers following head injury (i.e., decision-making - Iowa Gambling Task [IGT] and mood – depression) and possible amelioration of those challenges (through treatment) in both highly functioning university students with and without mild head injury (MHI) and in individuals with moderate traumatic brain injury (TBI). An arousal manipulation using emotionally evocative stimuli was introduced to manipulate the subject’s physiological arousal state. Seventy-five university students (37.6% reporting a MHI) and 11 patients with documented moderate TBI were recruited to participate in this quasi-experimental study. Those with head injury were found to be physiologically underaroused (on measures of electrodermal activation [EDA] and pulse) and were less sensitive to the negative effects of punishment (i.e., losses) in the gambling task than those without head injury, with greater impairment being observed for the moderate TBI group. The arousal manipulation, while effective, was not able to maintain a higher state of arousal in the injury groups across trials (i.e., their arousal state returned to pre-manipulation levels more quickly than their non-injured cohort), and, subsequently, a performance improvement was not observed on the IGT. Lastly, head injury was found to contribute to the relationship between IGT performance and depressive symptom acknowledgment and mood status in persons with head injury. This study indicates the possible important role of physiological arousal on socio- emotional behaviours (decision-making, mood) in persons with even mild, non-complicated head injuries and across the injury severity continuum.

The Mediating Role of Perceived Scholastic Competence in the Relationship Between Motor Coordination and Academic Performance

Children with developmental coordination disorder (DCD) are often referred to as clumsy because of their compromised motor coordination. Clumsiness and slow movement performances while scripting in children with DCD often result in poor academic performance and a diminished sense of scholastic competence. This study purported to examine the mediating role of perceived scholastic competence in the relationship between motor coordination and academic performance in children in grade six. Children receive a great deal of comparative information on their academic performances, which influence a student's sense of scholastic competence and self-efficacy. The amount of perceived academic self-efficacy has significant impact on academic performance, their willingness to complete academic tasks, and their self-motivation to improve where necessary. Independent t-tests reveal a significant difference (p < .001) between DCD and non-DCD groups when compared against their overall grade six average with the DCD group performing significantly lower. Independent t-tests found no significant difference between DCD and non-DCD groups for perceived scholastic competence. However, multiple linear regression analysis revealed a significant mediating role of 15% by perceived scholastic competence when examining the relationship between motor coordination and academic performance. While children with probable DCD may not rate their perceived scholastic competence as less than their healthy peers, there is a significant mediating effect on their academic performance.

The role of the nuclear receptor Nr5a2 in ovulation in mice

Le récepteur nucléaire Nr5a2 est exprimé dans l’ovaire, plus spécifiquement dans les cellules de granulosa et lutéales. Une déplétion conditionnelle de Nr5a2 dans les cellules de granulosa au stade de follicule primaire par croisement de souris Nr5a2-flox et Amhr2-Cre (Nr5a2f/fAmhr2Cre/+) génère des problèmes au niveau de l’expansion du cumulus, de l’ovulation et de la lutéinisation. Ainsi, nous estimons que Nr5a2 régule les connexions intercellulaires dans le follicule ovarien via la connexine 43 (Cx43), une protéine de jonction impliquée dans l’expansion du cumulus. Le premier objectif de l’étude était de déterminer si l’absence d’expansion du cumulus chez les souris Amhr2Cre-cKO est liée à l’absence de communication intercellulaire adéquate entre les cellules de granulosa et de cumulus dans les follicules préovulatoires. À cette fin, des ovaires de souris immatures Amhr2Cre-cKO et non transgéniques ont été prélevés (n=3) après un traitement de superstimulation utilisant les gonadotropines eCG suivie de hCG afin d’induire l’ovulation. Nous avons ainsi démontré, par RT-PCR, une sous-expression de Cx43 avant et au moment du stimulus ovulatoire (0 h et 2 h) chez le groupe Amhr2Cre-cKO (P<0.01), ce qui pourrait mener à un problème dans l’acquisition de la compétence développementale de l’oocyte. D’un autre côté, au moment de l’ovulation (12 h), l’ARNm de Cx43 est surexprimé dans le groupe Amhr2Cre-cKO, ce qui pourrait prévenir les cellules du cumulus de se détacher l’une de l’autre. Nous avons ainsi conclu que Cx43 est un gène sous le contrôle de Nr5a2 et qu’une régulation erronée de ce gène est une cause possible du problème d’expansion du cumulus chez les souris Amhr2Cre-cKO. Afin d’examiner le rôle de Nr5a2 dans l’ovulation et la lutéinisation à différents stades de la maturation folliculaire, nous suggérons que Nr5a2 module la séquence temporelle des événements menant à l’ovulation. En croisant des souris Nr5a2-flox et Cyp19-Cre (Nr5a2f/fCyp19Cre/+), l’expression de Nr5a2 a été interrompue dans les cellules de granulosa des follicules antraux et préovulatoires. Aucune portée n’a été obtenue de ces souris (n=4) durant un essai d’accouplement de 6 mois. Chez les souris Cyp19Cre-cKO on remarque la présence de structures s’apparentant à des cellules de type lutéales et les femelles âgées d’un an présentent des kystes folliculaires hémorragiques et une hypertrophie de l’épithélium en surface de l’ovaire. Les deux modèles transgéniques démontrent donc une absence de l’expansion du cumulus et de l’ovulation. En conclusion, Nr5a2 semble réguler différemment la folliculogenèse et l’ovulation dans les cellules de granulosa des follicules primaires et antraux.

Student self-assessment a feedback seeking strategy through competence evaluation

There is a body of literature that suggests that student self-assessment is a main goal in higher education (Boud et al., 1995; Tan, 2008); moreover new forms of work organization require a high level of skills and competences. The efforts to deal with competence gaps could be developed at many levels, such as employers, educational institutions, individuals and public agents. Employers could put into practice competence development programs to moderate these gaps. Educational institutions can restructure the curriculum to support students in attaining the competences that are essential in the labour market. Individuals themselves may deploy their resources (time and money) in general or specific competence training. Further, government agencies could fund competence promotion programs. Such challenges for education drive change in learning curricula and method, to properly include the competences required for developing global workers who can move beyond basic competence, to enhanced flexibility and adaptability. In performance assessment methods, there is a shift from the traditional exam-based assessments to more innovative task assessment, which considers performance in multiple different tasks carry out by students. ICTs make it technologically feasible to carry out a complete and complex selfassessment of competences, which provides immediate results to students or other recipients. In the case of students, the evaluation of competences is relevant as developing competences is part - if not all - of the objectives of education. Therefore, it is an important element of the quality of educational organizations (e.g., universities), and of their organizational success. Further, educational organizations may put special emphasis on some differentiating competences, which can be a means of positioning and differentiation from competitors. Competence assessment is an instrument to make students conscious of their strengths and weaknesses, leading to higher motivation to develop their own learning career

Nongenetic inheritance, linguistic competence, prenatal experience and behavior manipulation: recent contributions from behavioral neurobiology and neuropsychology to the explanation of behavior

This article gives an overview of presuppositions and explanations posed by behaviorist psychology (particularly its radical branch), cognitive–nativist sciences (i.e. psycholinguistics and a branch of cognitive psychology) and other disciplines regarding important psychological events such as anxiety, stress, fear, mood states and language. In relation to the discussion of environment versus genetics, contributions from behavioral neurobiology and neuropsychology are added, showing evidence of traits that can be multigenerationally inherited in a non-genetic way, which have an impact thought the life of organisms and on their way of interacting with the environment; ways in which behavior can be altered by recently unsuspected environmental agents or events, and the overlooked role of prenatal experiences in the explanation of behavior. The evidence calls into question presuppositions made by the academic disciplines listed above, and suggests alternative behavior reinterpretations and explanations
