PSYC 1 Lecture Notes - Lecture 5: Sensory Memory, Rafflesia, Attentional Blink
Document Summary
Attention: the tendency to respond to and remember some stimuli more than others: preattentive processing: sensory information that stands out immediately (bottom-up or stimulus-driven processing) Movement among still items: attentive processing: procedures that consider only one part of the sensory field at a time (top-down), stroop effect: Reading words we encounter is an automatic and preattentive process. The stroop effect exemplifies how preattentive and attentive processes differ. Refraining from reading and naming the color ink of the typeface makes large attention demands: questions: Noticing a snake on the trail while out hiking. Hearing someone say your name at a party. Attention bottleneck: attending to more than one stimulus at once taxes attentional resources. Items compete for our attention and information may be missed. Multi-tasking: even the conversations of passengers (halfalogues) are greatly distracting- they require more attention than hearing both sides of a conversation. Professor wants to predict which students will do better on the exam.
