. . . . . entries for 25.9.09 . . . . . "A professor sits at a computer, attempting to write a paper. The phone rings, he answers. It’s an administrator, demanding a completed ‘module review form’. The professor sighs, thinks for a moment, scans the desk for the form, locates it, picks it up and walks down the hall to the administrator’s office, exchanging greetings with a colleague on the way. Each cognitive task in this quotidian sequence – sentence-composing, phone-answering, conversation, episodic retrieval, visual search, reaching and grasping, navigation, social exchange – requires an appropriate configuration of mental resources, a procedural ‘schema’ [1] or ‘task-set’ [2]. The task performed at each point is triggered partly by external stimuli (the phone’s ring and the located form). But each stimulus affords alternative tasks: the form could also be thrown in the bin or made into a paper plane.We exercise intentional ‘executive’ control to select and implement the task-set, or the combination of task-sets, that are appropriate to our dominant goals [3], resisting temptations to satisfy other goals." I really think I am likely to enjoy working memory lab. :P
