Filter by:The aim of this study is to investigate the effects of different domains of executive function (EF) during dual task walking condition on brain activation and gait performance in healthy adults. There are two experiments will be conducted in this study. Experiment 1 is a pilot study to determine the same level of difficulty in 3 EF domains, including inhibition, working memory and cognitive flexibility. Experiment 2 is carried out to investigate the effects of 3 different domains of EF which difficulties are controlled on gait performance and brain activation in dual task condition. 10 subjects will perform Stroop test (2s/3s/4s to change question), backward digit spans (3/4/5 digits) and naming test in Experiment 1. In Experiment 1, the primary outcome is the correct response speed (CRS) while secondary outcome will be the brain activity. In Experiment 2, 30 subjects will perform the single cognitive task A (SCTA, Stroop test), single cognitive task B (SCTB, backward digit spans), single cognitive task C (SCTC, naming test), single walking task (SWT), dual task A (DTA, walking while performing cognitive task A), dual task B (DTB, walking while performing cognitive task B) and dual task C (DTC, walking while performing cognitive task C). The CRS, gait performance, brain activity and the dual task costs (DTC) will be recorded in the Experiment 2. Brain activities in prefrontal cortex (PFC), premotor cortex (PMC) and supplementary motor area (SMAs) will be measured by functional near-infrared spectroscopy (fNIRS) during this study. One-way ANOVA with Tukey post-hoc test will be performed to establish the effect of different type of executive task on CRS or the brain activity. The differences of gait parameters and brain activity in different condition in the Experiment 2 will be examined by one-way ANOVA with repeated measured. Furthermore, the Pearson correlation coefficient will be used to examine the correlation of brain activation and executive function performance or gait parameters.
Objective: To determine the efficacy of computer-assisted cognitive remediation (CACR) in patients with chronic schizophrenia in the community settings. Study Design: Single-blinded prospective, pre-test/post-test randomized controlled trial (RCT) will be conducted in 2 groups of participants that receiving training in community settings. Treatment groups will attend individualized CACR programme using CogniPlus® while control group will continue attend conventional treatment as usual (TAU). Assessment on the means difference in assessing functions will be done after the study. Samples: 80 patients with stable and chronic schizophrenia will be recruited from the community, using a sampling frame of selected diagnosis and homogeneity. Expected Findings: Find out the training effects of selected CACR on EF and daily functioning in patients with schizophrenia.
The aim of this study is to examine the effectiveness of a play-based intervention designed to support the development of executive functioning in 3-5-year-old children. The intervention is implemented in the day care setting as a part of early childhood education in collaboration with parents and local healthcare and social welfare workers. The study hypothesizes that the intervention as an add-on to normal early childhood education brings added benefits to the development of children's executive functioning in comparison to early childhood education without the add-on.
The main purpose of vHAPPY is to pilot test a new type of virtual family-based healthy lifestyle program for children aged 8-14 with obesity and their caregivers. vHAPPY aims to (1) Transition a previously developed acceptance-based behavioral treatment to web-based platform, utilizing qualitative and quantitative program evaluation data from past participants. (2) Determine the feasibility, acceptability, and preliminary outcomes of the adapted web-based treatment. (3) Evaluate whether the adapted web-based treatment (self-guided treatment + brief coaching) is similar to the traditional treatment (interventionist-guided treatment) in terms of feasibility, acceptability, and preliminary outcomes utilizing a non-randomized sequential arm design.
The aim of this study was to develop an Indonesian computer-based game prototype that targets the clinical symptoms of ADHD as well as executive function and to investigate effectiveness through fMRI BOLD examination. This was a mix-method study design; the first step was an exploratory qualitative study using focused group discussion. The second step was 'the one group pre- and post-test design study' without any control. Ten primary school children who were drug-naïve and had a diagnosis of ADHD with no other mental or physical disorders participated in the study. Clinical improvement was measured by the CATPRS, BRIEF, and fMRI BOLD examination that focused on DLPFC-Hippocampus functional connectivity before and after 20 sessions of the Indonesian computer-based game prototype training. Data were analyzed using the paired t test and Pearson's correlation in SPSS for Mac version 21, and fMRI BOLD functional analysis was performed using SPM software version 12 and CONN Toolbox version 17. The hypothesis was: the Indonesian computer-based game prototype had an effect towards ADHD clinical symptoms and executive function that correlated with DLPFC-Hippocampus functional connectivity.
Developing theoretical, quantitative models of the basic cognitive mechanisms underlying human social decision-making, and understanding the influence of neuromodulators such as dopamine on these mechanisms, has important ramifications for both healthy and patient populations. In this proposal the investigators combine quantitative social measures, computational models, neuroimaging, and a pharmacological intervention to define the mechanisms of social decision-making.
In Portugal, 17.3% of children under 10 years old are overweight and 7.7% are obese. Research has shown the implementation of healthy lifestyle promotion programs and obesity prevention, however "best practices" are far from being defined. Also, the first five years of life are important for the executive functions development, namely memory, inhibition (including self-regulation) and flexibility, which includes creative thinking, thinking "outside of the box", important in problem solving. The importance of social and emotional dimensions, as well as physical health for the development of cognitive health is consensual, as sleep deprivation, low physical activity, unhealthy food may inhibit the proper development of executive functions. This project aims to evaluate the effectiveness of a healthy lifestyle promotion program on emotional, social and cognitive development and eating habits, sleep and physical activity in children between 12 and 42 months of age. A cluster randomised trial will be developed and 300 children, from 16 childcare centres will be invited to participate. Half of the childcare centres will be allocated to the control group and the other half to the intervention group. Data collection will occur before randomisation (at baseline) and after intervention. A feasibility study will be undertaken prior to the experimental study, in accordance with internationally accepted procedures. The investigators intend to implement the concept that the development of executive functions requires the combination of healthy eating, physical activity and sleep. The project will contribute with evidence-based to the cognitive, social and emotional development in children.
Purpose: In this study, the investigators will provide causal evidence for the role of alpha and theta oscillations in cognitive control. Participants: Participants must be healthy, between the ages of 18 and 35, right handed, able to provide informed consent, willing to comply with all study procedures, and be available for the duration of the study, speak and understand English. Procedures: Alpha and theta brain oscillations will be measured and then entrained using frequency specific rhythmic TMS during a retrospective cued cognitive control task.
This study evaluates the implementation of the BOKS program in three schools (K-8) in Revere, MA, and its effect on participating students with regard to BMI, cognitive, and quality of life outcomes. BOKS (Build Our Kids' Success) is a before-school physical activity program that has been implemented in over 2,000 elementary and middle schools. Two sessions will be held (Spring 2018 and Winter 2018. This is a cohort study evaluating the impact of program participation on child BMI, quality of life, and executive function.
