Document Summary

Target held in memory, using attention to hold it in your memory and find it: filter through distractions to selectively process just the target. Spatial configuration repeats and can map onto each other: although typically unaware of this repeating, we learn it and use it to speed our reaction time and speech response. Implications of contextual cueing: visual search is classic measure of attention and perception, memory can guide search, ca(cid:374)"t de(cid:448)elop a (cid:272)o(cid:373)plete u(cid:374)dersta(cid:374)di(cid:374)g of atte(cid:374)tio(cid:374) (cid:449)ithout a(cid:272)(cid:272)ou(cid:374)ti(cid:374)g for how it is guided by memory. Bottom up attention properties of visual stimuli guiding our attention. What is in our memory can influence what is considered salient in our environment. Top down attention using internal goals held in memory to guide our attention. Medial temporal lobe: mtl = hippocampus + parahippocampal cortex, perirhinal cortex + entorhinal cortex, strongly implicated in declarative long-term memory, adjacent to most anterior regions of ventral visual cortex (involved in perception of complex visual objects)
