• filter attenuation theory early filter does not completely block out unwanted info but only attenuates or reduces strength of unattended stimuli attenuated information does not reach consciousness
• attentional spotlight attention as spotlight can be moved across different regions of space. items within range of spotligt receive processing
• overt orienting change in positioning of senses with goal of improving perception
• covert orienting attention directed to a location other than the focus of eyes
• exogenous orienting driven by stimuli
• endogenous orienting orienting of eyes on basis of intention. attention not automatically captured by stimulus but is INTENTIONALLY allocated to stimulus
• inhibition of return responses to target at a location where an uninformative cue occured are SLOWER than responses to targets at other locations   period between presentation of cue and target longer  than 300 ms!
• feature search target which differs from all distractors on basis of single feature
• conjunctive search target defined by a conjunction of features characterized by relatively inefficient search such that search time increases with number of items in display
• feature integration theory theory of visual search in which attention must be allocated to stimulus locations in order to integrate features of stimulus presented at that location features receive preferential processing and registered in early early automatically and in parallel across visual field

• theory of visual attention (TVA) selected simulatneously: 1. perceptual item 2. categorization for the item selection seen as choice among categorizations of perceptual inputs early+late selection theory
