Document Summary

Interactions between attention and perception: perceptions are competing for attention, the spatial configuration can map onto each other. Although typically unaware of repeated contexts, but people nevertheless learn them unconsciously, and use this to speed search: people are faster when there is a repetition of configuration. Study: old: 12 randomly generated configurations that repeated throughout the experiment, new: target always in one of 12 locations; otherwise configuration was generated randomly on each trial, results. Still increase in performance with new (non-repeated configurations: practice benefit. Implications of contextual cuing: can use old information to increase performance.

Interaction between memory and perception: medial temporal lobe = hippocampus + parahippocampal cortex, perirhinal cortex + entorhinal cortex. Strongly implicated in declarative long term memory: mtl is adjacent to most anterior regions of ventral visual cortex (perception of complex visual objects)
