Document Summary
Selective attention: conscious process of selecting or focusing on one or more stimuli. Overt attention: occurs when the focus coincides with the sensory orientation: directing our senses (eyes/ears) and attention in the same direction. Covert attention: focus independent of sensory orientation: focused on one thing visually, and another attentionally, ex: teacher with eyes in the back of their head. Shadowing: subjects must focus on just one of two or more simultaneous stimuli: typically tested through dichotic presentation: simultaneous delivery of stimuli to left and right ear asked to report stimuli from one ear. Can report very little from the other just simple characteristics like sex of speaker. Inattention blindness is a failure to perceive non-attended visual stimuli. Divided-attention tasks: subjects are asked to process two or more simultaneous stimuli: show attention is limited. Very dif cult to attend to more than one thing at a time.
