Task switching after cerebellar damage Academic Article uri icon


  • The authors of this study investigated task switching following cerebellar damage. The study groupconsisted of 7 children and adolescents ( M age 13.8 years) who underwent surgical removal of abenign posterior fossa tumor. They were tested at a suf´Čücient interval after surgery ( M lag 6.13 years)for restoration of normal cognitive skills and intelligence. Although all showed normal learning of thetask compared with control participants, when rapid behavioral changes were required (short preparationtime), they exhibited behavioral rigidity manifested by enhanced switching cost. These results are in linewith another study on serial reaction time with the same patients (A. Berger et al., in press). They haveimportant implications for our understanding of the cognitive sequelae of early cerebellar damage as wellas the involvement of the cerebellum in task switching.Keywords: task switching, executive control, cerebellum, posterior fossa tumor
