摘要: A quantitative investigation of the ability to carry out a variety cognitive tasks was performed in 3 patients who had sustained traumatic injuries which involved prefrontal structures.

Explanations for their difficulty multiple subgoal terms memory or motivational problems could be excluded. It is argued that problem arose from an inability reactivate after delay previously-generated intentions when they are not directly signalled by stimulus situation.
