An Investigation of Attentional and Inhibitory Processes During Active Visual Search in Humans

The goal of this study is to investigate the finding that there are large individual differences in how participants move their eyes during active visual search. For example, some individuals tend to fixate, that is point their eyes steadily at a single location, for longer than other individuals before moving to another location. This experiment will use behavioral tasks to measure an individual's attentional and inhibitory functioning, and then see how each of these contributes to between-participant variability in eye movement behavior during visual search.

The Bucharest Early Intervention Project

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.

E-Emotio Project A Gamified Preventive School-based Paradigm Using Virtual Reality Technologies for Improving Emotional Regulation in Children and Adolescents.

Introduction and Significance: Preventive interventions have been shown to reduce the risk of developing anxiety and depression, making them a critical focus area in mental health promotion for children and adolescents. Enhancing emotion regulation (ER) skills in young people is one approach to preventing anxiety and depression, as ER involves cognitive processes of modifying thoughts and behaviors to manage emotional responses in different contexts. Executive functions (EF), such as cognitive flexibility, working memory, and inhibition, play a crucial role in ER development and regulation in children and adolescents. Recently, immersive virtual reality (IVR) has emerged as a novel tool for improving cognitive training interventions' accessibility and effectiveness. IVR allows users to experience immersive, three-dimensional environments, where they can interact with objects and events in a highly engaging and realistic way. Considering these developments, this study aims to explore the potential benefits of Enhance VR, a gamified IVR program designed to improve ER skills and reduce anxiety and depressive symptoms among children and adolescents. Methodology: The study will be a longitudinal, parallel, single-blind, randomized controlled pilot trial involving 80 Spanish - or English-speaking participants aged 10 to 16 years old. Participants will be excluded if they have severe psychiatric or neurodevelopmental disorders, physical, motor, or sensory impairments, or a risk of experiencing high cybersickness symptomatology during the VR experience. Participants will be randomly allocated into two groups: an experimental group receiving E-Emotio VR and a control group receiving a placebo-based VR relaxation experience. Both VR interventions will last five weeks, two times a week, for 30 minutes. The experimental group will engage in six games targeting cognitive flexibility, planning, reappraisal strategies, working memory, divided and sustained attention, and processing speed. The control group will be immersed in ten different nature-based VR environments and perform relaxation exercises. Baseline and post-intervention assessments will be conducted using age-adapted validated measures of depressive and anxiety symptoms, ER, executive function (working memory, cognitive flexibility, inhibition, and planning), and attention. Following the intervention, the assessment battery will be re-administered by a blinded assessor, and statistical analyses will be conducted for all the primary and secondary measures assessed before and after the intervention in both groups. Conclusion: In summary, this study aims to contribute to the development of effective preventive interventions for emotion regulation and mental health symptoms in children and adolescents by promoting ER through gamified VR cognitive training. The study's findings could have significant implications for mental health research, educational and clinical practice. By exploring the potential benefits of VR cognitive training, this research has the potential to inform future studies and clinical interventions aimed at improving young people's mental health and well-being. The gamification of cognitive training interventions could be a powerful tool for increasing engagement and motivation among young people, making them more likely to participate in such interventions.

Cognitive Control & the Functional Organization of the Frontal Cortex

The goal of this basic experimental clinical trial is to understand the effect of multitasking practice on the structure of neural representations of tasks in the human lateral prefrontal cortex and control brain regions. The main question it aims to answer is: What changes in neural representational structure predict improvements in multitasking behavior due to multitasking practice? Healthy human participants will learn two independent tasks, each mapping a set of stimuli to motor responses based on different rules. Participants will be randomized to one of two interventions. Participants assigned to the multitask practice intervention (MPI) will practice multitasking the two tasks over multiple days. Those assigned to the single-task practice intervention (SPI) will instead practice each task separately while controlling for the total number of practice opportunities associated with each task across the interventions. Both before and after the practice, the ability of all participants to perform both tasks simultaneously will be behaviorally measured using a well-established psychological refractory period (PRP) paradigm, and their neural representations will be measured using functional MRI while they perform the two tasks. Researchers will then compare improvements in multitasking behavior across the two groups, as well as changes in neural representational geometry of the tasks in the lateral prefrontal cortex and control brain regions, and test whether multitasking training is associated with specific changes in neural representations in the lateral prefrontal cortex.

MOVI-OLE! [Open Learning Environments]

This study will evaluate the effectiveness of MOVI-OLE! (Open Learning Environment), a school-based intervention designed to reduce sedentary time and enhance multiple aspects of child development, including cognitive function, physical fitness, body composition, psychological well-being, and student engagement. The intervention combines dynamic classroom furniture with student-centered teaching practices. Additionally, a qualitative component will explore how students, teachers, and families perceive the feasibility and acceptability of implementing MOVI-OLE! in real-world school settings.

SCREENS: Sleep, Circadian Rhythms, and Electronics in the EveNing Study

The proposed project aims to disentangle the impact of evening light exposure emitted from tablet devices from the impact of arousing media content on children's sleep regulation, circadian physiology and next-day emotion regulation and executive functioning.

Comparison Between Plyometrics and Calisthenics on Executive Function in School Going Children

The goal of this clinical trial is to compare the effects of calisthenics and plyometric exercises on executive functions in school-going children. The main questions it aims to answer are: * Will calisthenics exercises have a better effect on executive functions compared to plyometric exercises in school-going children? * How do these exercise interventions impact selective attention, working memory, inhibitory control, and cognitive flexibility in children? Researchers will compare a calisthenics exercise group, a plyometric exercise group, and a control group (no intervention) to see if there are differences in executive function outcomes. Participants will: * Be male school-going children aged 8-12 years * Be randomly assigned to one of three groups: calisthenics, plyometric, or control * Complete baseline assessments of executive function * Participate in their assigned exercise program 3 times per week for 8 weeks (exercise groups only) * Complete follow-up assessments of executive function at 4 weeks and 8 weeks * Perform tests measuring selective attention, working memory, inhibitory control, and cognitive flexibility

Executive Function and Parenting in Childhood

Deficits in executive functioning (EF) disproportionately impact children living in poverty and increase risk for psychopathology, particularly disruptive behavior disorders. This randomized clinical trial seeks to determine whether childhood EF, assessed across neural and behavioral units of analysis, is an experimental therapeutic target that can be directly modified through caregiver participation in the Chicago Parent Program (CPP), if increases in EF predict reduced disruptive behavior trajectories in low-income children over a short-term follow-up period, and identify which CPP-driven parenting skill improvements are the most influential in modifying EF. This work will contribute new knowledge as to whether a cost-efficient parenting intervention, developed for and with low-income families raising young children in poverty, can modify EF, a neural behavioral mechanism implicated in risk for childhood disruptive behavior problems.
