Document Summary

Lecture 25 the cost / benefits of priming. Different patterns of performance based on 2 different conditions. Low validity condition: good benffits, very low costs to being misled. Repetition priming: warming up one detector that doesn"t have any effect on another detector, priming helps you, misleading doesn"t hurt any worse than neutral. Expectation-based priming: also produces a benefit when you get what you expect, but, also a cost if you don"t get what you expect, expecting one thing hurts you in perceiving another (this is your attention budget) Attention deals with preparing for upcoming info, and is a limited capacity system. Mental tasks have a cost": can do multiple things at once if it is within your mental budget, if you go over your budget, performance suffers. Our representation of the visual world is not as detailed / veridical / seamless as we think. We often overlook important details of our visual world, especially when attention is preoccupied.
