Filter by:Executive function play a key role in boosting human behavioural performance. Based on scientific literature, it is still controversial whether electroencephalography-based neurofeedback (EEG-NFB) represents an effective technique for enhancing healthy adults' executive function. This study evaluates generalized effects of 3-week EEG-NFB training, using self-regulation of the theta to beta wave ratio (TBR), on executive function in healthy adults. The subjects are an uniform group of healthy young right-handed males divided into two equal groups. The trained group (TR) performs 3-week EEG-NFB training (three sessions per week) focused on a cognitive self-regulation of TBR (to achieve the lower TBR values as beneficial cognitive effect), while the control group (CO) does not participate in the EEG-NFB training. Cognitive function are rated before and after 3-week EEG-NFB training by psychological tests: Trail Making Test (TMT, parts A and B) and the Stroop Test (ST, parts I and II). This project is important for the future development of effective EEG-NFB protocols to be used by healthy people to improve their behavioural performance.
Background: Early childhood is the most critical and rapid period of complete and healthy physical and cognitive development in human life. Executive function appears in early childhood and develops rapidly through complex coaction between environment and developmental processes. The preschool period is also characterized by a rapid growth in fundamental movement skills, physical activity and physical fitness. The scientific research on the relationship between fundamental movement skills, physical activity, physical fitness and executive function in preschoolers remains to be explored. Objective: The purpose of this study was to examine the cross-sectional relationship between fundamental movement skills, physical activity, physical fitness and executive function in preschool children while controlling for potential confounding variables, examine the prospective influence (independent and interactive role) of preschooler's fundamental movement skills, physical activity and physical fitness on executive function, observe the preschoolers' fundamental movement skills, physical activity, physical fitness and executive function changes with age, and investigate gender and age differences in preschoolers' fundamental movement skills, physical activity, physical fitness and executive function. Method: The proposed study consists of two phases, phase 1 is a cross-sectional study. Five hundred and five children aged 3-5 years will be recruited. The Test of Gross Motor Development Third Edition (TGMD-3) was used to assess children's fundamental movement skills. Preschool children's physical activity was monitored by accelerometer ActiGraph GT3X-BT. Physical fitness was tested using handgrip, 4*10m shuttle run, 20m shuttle run, 30s sit-ups, sit and reach, and balance beam. Executive function was tested by computer-based tasks including animal stroop, safari training and stop signal task. Phase 2 is a 12-month follow-up study. In the phase 2, all children enrolled in the baseline study will be followed up, the measurements and contents of the follow-up are the same as the baseline instrument.
The purpose of this study is to determine the long term effects of early intervention (placement into foster care) on physical, cognitive, social and brain development and psychiatric symptomatology in previously institutionalized children.
