PSYC 2400H Lecture Notes - Lecture 4: Stroop Effect
Document Summary
Participants are presented with two verbal messages simultaneously, typically one to each other ear, and are asked to focus on (ie attend to) only one of them. They are then asked to respond to a series of questions about what they heard, most often about the message played to the unattended ear. Attending to relevant information and ignoring irrelevant information. The ability to attend to one conversation when many other conversations are going on around you. A task in which the subject is exposed to two messages simultaneously and must repeat one of them. A hypothetical mechanism that would admit certain messages and block others. Occurs when we are exposed to two events simultaneously, but attend to only one of them. The hypothesis that attention prevents early perceptual processing of distractors. The hypothesis that we perceive both relevant and irrelevant stimuli, and therefore must actively ignore the irrelevant stimuli in order to focus on the relevant ones.
