PSYB57H3 Chapter Notes - Chapter 4: Occipital Lobe, Hemispatial Neglect, Frontal Lobe
Document Summary
Participants were instructed to pay attention to one of these inputs- the attended channel and the other is the unattended channel. To make sure participants were paying attention, they were usually given a task called shadowing. The attended channel contained a recording of someone speaking and participants listened to this speech and had to repeat it back. Unattended speech could only be detected by a few participants. Cocktail party effect where things with personal importance are noticed, even though rest of the unattended channel is perceived only as an undifferentiated blur. Desired information (attended channel) is not filtered out and so goes on to receive further processing. Filtering is rather specific and is done on a distractor by distractor basis- as if entry lacked the broad ability to separate desirable guests in general from undesirable ones. Sentry seems to have assignment of blocking specific, already identified gate crashers. We block processing of distractors and promote processing of desired stimuli.
