Document Summary

Different tasks compete with each other for some mental resource. Resources serve as an energy supply, drawn on by all tasks. The greater the load, the greater the interference with other tasks. Higher perceptual load increased inattentional blindness. The mental resources and processes that are used to set goals, choose task priorities and avoid conflict among competing habits and responses. Executive control allows you to shift plans or change strategy. Executive control can only handle one task at a time. Puts limits on your ability to multitask divide your attention. Damage to the prefrontal cortex (pfc) crucial for executive control. Patients have enormous difficulty in shifting tasks. Perseveration error a tendency to produce the same response over and over even when it"s plain that the task requires a change in the response. A pattern of goal neglect failing to organize their behavior in a way that moves them toward their goals.
