Cognitive Evaluation of Patients With Eating Disorders

The goal of this cross - sectional observational study is to improve understanding of the psychological and cognitive characteristics of Feeding and Eating Disorders (FEDs), a group of conditions that represent a growing public health concern due to their significant impact on physical health, emotional well-being, and everyday functioning. Within this broader diagnostic category, particular attention is given to Avoidant/Restrictive Food Intake Disorder (ARFID), a diagnosis introduced in the DSM-5 and still relatively underexplored compared to other feeding and eating disorders. Despite its clinical relevance, ARFID remains less well understood in terms of its underlying cognitive and psychological mechanisms. Individuals with ARFID often experience severe food avoidance or restriction that is not driven by weight or shape concerns, but rather by sensory sensitivities, fear of negative consequences of eating, or a lack of interest in food. For this reason, investigating ARFID can offer important insights into the diversity of mechanisms involved in feeding and eating disorders as a whole. The study has two main objectives. The first objective is to examine the cognitive profile of individuals with ARFID, with a specific focus on autistic traits and cognitive flexibility, as previous research suggests potential overlaps between ARFID and neurodevelopmental conditions such as Autism Spectrum Disorders. Cognitive flexibility refers to the ability to adapt thoughts and behaviors in response to changing situations, and reduced flexibility may contribute to rigid eating patterns and food avoidance. The second objective is to explore the role of body representation (how individuals perceive and mentally represent their own body) and inhibitory control (the ability to regulate or suppress automatic responses) in shaping the cognitive and behavioral features of ARFID and other feeding and eating disorders. These processes may help distinguish ARFID from other diagnoses and clarify shared and disorder-specific mechanisms across the FED spectrum. The study involves adult participants of all genders, including individuals diagnosed with ARFID, anorexia nervosa, and bulimia nervosa, as well as healthy control participants without a history of feeding or eating disorders. This design allows meaningful comparisons between different diagnostic groups and with the general population. The main questions the study aims to answer are: Do individuals with ARFID show a distinct cognitive profile, particularly in terms of autistic traits and cognitive flexibility, compared to individuals with other feeding and eating disorders and healthy controls? How do body representation and inhibitory control contribute to differences in eating-related behaviors across feeding and eating disorders? Are there differences in brain activity associated with implicit, automatic attitudes toward food in individuals with feeding and eating disorders compared to healthy individuals? Where comparison groups are included, researchers will compare participants with ARFID, anorexia nervosa, bulimia nervosa, and healthy controls to examine differences in cognitive functioning, psychological characteristics, and neural responses related to food processing. Participants will be asked to take part in a series of non-invasive and well-established research activities, designed to be accessible and safe. These include: Completing self-report questionnaires assessing autistic traits, body image perception, and general psychological well-being; Performing computer-based tasks that assess cognitive flexibility and decision-making; Completing behavioral tasks designed to measure inhibitory control and automatic associations with food-related stimuli;

Adaptive Music Therapy for Psychosocial and Cognitive Functions of Older Adults

The proposed study is a pilot study that aims to understand if the Pi Electronics adaptive music intervention (AM) is effective to promote positive psychosocial and cognitive outcomes, over and above a traditional music intervention (TM) among healthy older adults. This study will contribute to the ongoing literature on the benefits of music interventions and provide insight on how emerging technology can enhance the therapeutic effects of music as a viable intervention for older adults. The study will adopt a three-arm randomized controlled trial (RCT). Eligible participants will be randomized into one of three groups: traditional music therapy group (TM), Pi Electronic's adaptive music program (AM), and a waitlist control group (CG). Informed consent will be collected from all participants. All three groups will complete outcome measures at three sessions: pretest, posttest, and at a three-month follow-up, but only the TM and AM group will receive music between the pretest and posttest sessions, spanning for 4 weeks, with 4 music therapy sessions per week, and each session lasting 30 minutes. Data will be analyzed for each outcome variables to understand the group differences in the performance on the psychosocial and cognitive outcome measures. The study will also validate the Pi Electronics EEG headset with the BioSemi, 64-channel EEG system.

Effects of Transcutaneous Auricular Vagus Nerve Stimulation on Cognitive Performance and Sex Differences

This study investigates the effects of transcutaneous auricular vagus nerve stimulation (taVNS) on cognitive performance in healthy adults. The study uses a sham-controlled, cross-over design in which each participant receives both active taVNS and sham stimulation in separate sessions. Each participant completes both conditions (active and sham) in a randomized order using a crossover design. Cognitive performance will be assessed before and after each session using standardized tests. The study also explores whether males and females respond differently to taVNS, in order to identify potential sex-related differences in cognitive outcomes.

Can Training Balance, or Enjoying Music, Improve Attention, Problem-solving and/or Behavior Control Abilities?

This randomized controlled trial will investigate the hypothesis that since balance and executive functions (EFs) require a similar neural circuit and EFs are recruited when trying to maintain balance, that training balance might improve EFs as well as balance. There will be an active control condition (watching music videos) and a no-treatment condition. Children (18-12 years old) will be randomly assigned to one of these conditions for 12 weeks (36 per condition). The balance and music conditions will involve 15-min sessions 3x/week and a weekly check-in session with an investigator. Participants will be assessed pre-intervention, immediately post and 3-months post.

Orchestra in Class, a Novel Booster for Executive Functions and Brain Development in Young Primary School Children

How to optimally stimulate the developing brain is still unclear. Executive functions (EF) exhibited substantially stronger far transfer effects in children who learned to play a musical instrument than in children who acquired other arts. What is crucially lacking is a large-scale, long-term genuine randomized controlled trial (RCT) in cognitive neuroscience, comparing musical instrumental training (MIP) to another art form and a control group. Collected data of this proposal will allow, using machine learning, to build a data-driven multivariate model of children's interconnected brain and EF development over the first 2 years of their academic curriculum (6-8 years), with or without music or other art training.
