Document Summary
The door study- simons and levin (1998): inattention blindness and change blindness. Attention- focalization and limitation of information processing resources. Can manipulate limited capacity resources by giving an attentional demanding task- don"t have attentional space left over to detect changes in environment. Believed that attention can be limited at each of the 3 stages of information processing (stimulus identification, response selection, response programming. **study: fmri study looked at functional neuron correlates associated with lapses in attention or action slips. Lapses of attention- unexpected outcome associated with daily activities of living (ex. coffee in cereal) Theory: lapses in attention are reduced activity of frontal monitoring regions just before you"re about to perform a task. Hypothesis 1: lapses of attention originate from momentary reduction in activity of frontal regions just before a behaviourally relevant stimulus. Perform a global local task: global component is the s- local component is small s making up a h.
