Document Summary
Subject not allowed to move gaze from central cue: when arrow pointing to left: block on left (valid cue) was detected faster than block on right (invalid cue). Participant has to repeat message from a specific ear. Participants have little to no idea about what is being said in unattended ear: filter theory of attention: out in the world there may be multiple sensory input channels impinging on sensory receptors. Inattentional blindness: stimulus presented briefly and then masked with a jumbled pattern, task is a difficult discrimination which is longer, horizontal or vertical segment. Task 1 is to name the green letter, task 2 is to determine whether there is a red x . One group of subjects does both tasks, other group just does task 2: results show that task 2 is easy for group 2, but not for group 1.
