New paper in press: an fMRI investigation of the conflict between goal-directed and habitual control

“Conflicted between goal-directed and habitual control – an fMRI investigation” by Poppy Watson, Guido van Wingen, and Sanne de Wit will soon appear in eNeuro.

In this functional MRI study we investigated the neural basis of performance on the slips-of-action paradigm -a task that has been used in previous studies to assess the balance between goal-directed and habitual control.

New publication on individual differences in habitual performance in experimental and real-life settings

The authors investigated whether people differ in their propensity to form habits, by relating individual differences on a computer task measuring habitual behavior to habit formation tendencies in real life. Habit formation in real life was measured by covering the key to the participant’s home with a new cover. This cover was later switched to a different key and changes in the key-selection process were measured. Participants that performed better on the computer task also seemed to require less attention to adjust to the switching key situation.

New article on impaired goal-directed control in adolescent OCD

In this article, Julia Gottwald, Sanne de Wit, and colleagues investigated performance of teenagers with obsessive-compulsive disorder (OCD) on critical cognitive domains for daily functioning and academic success, including goal-directed behavioral control, cognitive flexibility, learning, and memory. Patients demonstrated a significant learning and memory impairment compared to healthy control subjects, as well as impairments in goal-directed goal and cognitive plasticity. These results add to our understanding of  juvenile OCD.
