Somatosensory processing in neurodevelopmental disorders

The purpose of this article is to review the role of somatosensory perception in typical development, its aberration in a range of neurodevelopmental disorders, and the potential relations between tactile processing abnormalities and central features of each disorder such as motor, communication, and social development. Neurodevelopmental disorders that represent a range of symptoms and etiologies, and for which multiple peer-reviewed articles on somatosensory differences have been published, were chosen to include in the review. Relevant studies in animal models, as well as conditions of early sensory deprivation, are also included. Somatosensory processing plays an important, yet often overlooked, role in typical development and is aberrant in various neurodevelopmental disorders. This is demonstrated in studies of behavior, sensory thresholds, neuroanatomy, and neurophysiology in samples of children with Fragile X syndrome, autism spectrum disorders (ASD), attention deficit hyperactivity disorder (ADHD), and cerebral palsy (CP). Impaired somatosensory processing is found in a range of neurodevelopmental disorders and is associated with deficits in communication, motor ability, and social skills in these disorders. Given the central role of touch in early development, both experimental and clinical approaches should take into consideration the role of somatosensory processing in the etiology and treatment of neurodevelopmental disorders

Virtual environments as memory training devices in navigational tasks for older adults.

Cognitive training approaches using virtual environments (VEs) might counter age-related visuospatial memory decline and associated difficulties in wayfinding. However, the effects of the visual design of a VE in route learning are not fully understood. Therefore, we created a custom-designed VE optimized for route learning, with adjusted levels of realism and highlighted landmark locations (MixedVE). Herein we tested participants' route recall performance in identifying direction of turn at the intersection with this MixedVE against two baseline alternatives (AbstractVE, RealisticVE). An older vs. a younger group solved the tasks in two stages (immediate vs. delayed recall by one week). Our results demonstrate that the MixedVE facilitates better recall accuracy than the other two VEs for both age groups. Importantly, this pattern persists a week later. Additionally, our older participants were mostly overconfident in their route recall performance, but the MixedVE moderated this potentially detrimental overconfidence. Before the experiment, participants clearly preferred the RealisticVE, whereas after the experiment, most of the younger, and many of the older participants, preferred the MixedVE. Taken together, our findings provide insights into the importance of tailoring visualization design in route learning with VEs. Furthermore, we demonstrate the great potential of the MixedVE and by extension, of similar VEs as memory training devices for route learning, especially for older participants

Situational awareness within objective structured clinical examination stations in undergraduate medical training - a literature search

Background: Medical students may not be able to identify the essential elements of situational awareness (SA) necessary for clinical reasoning. Recent studies suggest that students have little insight into cognitive processing and SA in clinical scenarios. Objective Structured Clinical Examinations (OSCEs) could be used to assess certain elements of situational awareness. The purpose of this paper is to review the literature with a view to identifying whether levels of SA based on Endsley's model can be assessed utilising OSCEs during undergraduate medical training. Methods: A systematic search was performed pertaining to SA and OSCEs, to identify studies published between January 1975 (first paper describing an OSCE) and February 2017, in peer reviewed international journals published in English. PUBMED, EMBASE, PsycINFO Ovid and SCOPUS were searched for papers that described the assessment of SA using OSCEs among undergraduate medical students. Key search terms included "objective structured clinical examination", "objective structured clinical assessment" or "OSCE" and "non-technical skills", "sense-making", "clinical reasoning", "perception", "comprehension", "projection", "situation awareness", "situational awareness" and "situation assessment". Boolean operators (AND, OR) were used as conjunctions to narrow the search strategy, resulting in the limitation of papers relevant to the research interest. Areas of interest were elements of SA that can be assessed by these examinations. Results: The initial search of the literature retrieved 1127 publications. Upon removal of duplicates and papers relating to nursing, paramedical disciplines, pharmacy and veterinary education by title, abstract or full text, 11 articles were eligible for inclusion as related to the assessment of elements of SA in undergraduate medical students. Discussion: Review of the literature suggests that whole-task OSCEs enable the evaluation of SA associated with clinical reasoning skills. If they address the levels of SA, these OSCEs can provide supportive feedback and strengthen educational measures associated with higher diagnostic accuracy and reasoning abilities. Conclusion: Based on the findings, the early exposure of medical students to SA is recommended, utilising OSCEs to evaluate and facilitate SA in dynamic environment

Developmental outcomes at preschool age after fetal exposure to valproic acid and lamotrigine: Cognitive, motor, sensory and behavioral function

This prospective, observational study assessed the development of preschool children aged 3–6 years, 11 months (n = 124) after in-utero anti-epileptic drug (AED) monotherapy exposure to valproic acid (VPA) (n = 30, mean age 52.00[±15.22] months) and lamotrigine (LT) (n = 42, mean age 50.12[±12.77] months), compared to non-exposed control children (n = 52, mean age 59.96[±14.51] months). As a combined group, AED-exposed children showed reduced non-verbal IQ scores, and lower scores on motor measures, sensory measures, and parent-report executive function, behavioral and attentional measures. When the VPA- and LT-exposed groups were analyzed separately, no cognitive differences were found, but control-VPA and control-LT differences emerged for most motor and sensory measures as well as control-VPA parent-report behavioral and attentional differences. No differences were noted between the VPA and LT groups. These findings suggest that VPA- and LT-exposed children should be monitored on a wider range of developmental measures than currently used, and at differing developmental stages

Training teams in managing projects in a matrix structure

Projects are performed in different kinds of organizations: functional structure, project-based structure or matrix structure, The matrix organization is a combination of the functional organization and the "pure" project organization. In a matrix organization, there are usually two chains of command. The chain dealing with issues related to the functional division and the chain dealing with issues related to the project. Due to the split authority between project managers and functional managers, management becomes much more complicated. The cooperation between the project managers is vital for the matrix organization to perform well. Therefore, training teams of project managers in the matrix structure environment is required. A new method for training teams of project managers is presented. The proposed method is based on a real-time simulation called the Project Team Builder (PTB). PTB simulates a dynamic, stochastic multi-project management environment. A project management course for graduate students in systems engineering utilized PTB. The students used the simulator in a multi-user multi-project mode. A class of undergraduate engineering students participated in the same experiment as a control group. The 132 participants were divided into teams of three students (44 teams) which performed repetitive simulation-runs. Three factors were investigated: 1. Previous experience 2. History recording mechanism, and 3. Team debriefing process. The findings indicate that for the initial learning phase, and for the transfer to different scenario phase, these three independent factors affect the performances. Furthermore, the interactions between the experience and history factors; between the experience and debriefing factors; and between the history and debriefing factors were all significant. Based on these findings a new paradigm for simulation-based team- learning model in a matrix organization structure is presented. The new model includes integration of history mechanism and debriefing procedure in the KoIbs Team Learning Experience model. Copyrigh
