Frontal lobe dysfunction and everyday problem-solving: social and non-social contributions.

Everyday problem-solving involves both non-social executive processes, social and emotional processes, and draws upon social and practical knowledge. A series of studies including both adult-acquired lesions and neurodevelopmental disorders is reviewed examining problem-solving on a real-life-type task that involves generating a range of solutions to brief problem scenarios and selecting preferred solutions to solve the problems. Impairments in problem-solving are described in groups of participants with left anterior frontal lobe lesions, Tourette's syndrome and Asperger's syndrome. By contrast, healthy older people did not show problem-solving deficits on the same task. The possible contributions of non-social executive skills, social and emotional skills, and knowledge acquired from experience are each considered in relation to everyday performance. Multiple cognitive/emotional routes to the development of everyday life difficulties pose a complex challenge both in understanding the nature of the relevant processes and in developing adequate methods for management and rehabilitation.
