Analysis Of The Effect Of A Fine Manual Skills Intervention In A Specific Context On The Linguistic Processing of Healthy Young Adults

This is a randomized, single-blind clinical trial that will include healthy individuals between the ages of 19 and 24. Participants with previously diagnosed neurological and/or psychiatric disorders, a history of traumatic brain injury, use of psychoactive substances or medications that may affect cognition, and pregnant women or women suspected of being pregnant will be excluded. The sample will be a convenience sample, with participants randomly allocated to intervention and control groups (1:1), and the sample size calculation will be based on a pilot study. Participants will be assessed at two different time points, before and after the intervention, for fine manual dexterity and syntactic language processing. The intervention group will undergo fine manual dexterity training in a specific context, while the control group will undergo an intervention with a less complex task and without a specific context. Both protocols will consist of 20-minute sessions, held five times a week over two weeks, in a synchronous online format, via the Google Meet videoconferencing platform.
