PSY 108 Lecture Notes - Lecture 5: Inattentional Blindness, Stroop Effect, Boogaloo
Document Summary
If attention operates early in the processing stream, what is important may not be clear yet. If you are made to do a hard task, you need all your weight on that, and are less aware of everything else but strong inputs might still come through. Applying cognitive psychology: stage magic (example of inattentional blindness) Visual search (treisman: without attention, we cannot bind features together. Implication - illusory conjunctions; searches that require binding should not operate over the whole visual field at once (attention should be required) Searches for a single feature are very fast: focusing your attention involves a trade-off. If you focus your attention broadly, you can take in many inputs at once (faster) Since you"re taking in multiple inputs simultaneously, you may not know which feature belongs with which. If you focus your attention narrowly, you"ll be slower in search but with information coming from just one input, you"ll know how to features are combined.
