Wasserman, Edward A.; Castro, Leyre; Freeman, John H. – Learning & Memory, 2012
Same-different categorization is a fundamental feat of human cognition. Although birds and nonhuman primates readily learn same-different discriminations and successfully transfer them to novel stimuli, no such demonstration exists for rats. Using a spatial discrimination learning task, we show that rats can both learn to discriminate arrays of…

Norrholm, Seth D.; Jovanovic, Tanja; Vervliet, Bram; Myers, Karyn M.; Davis, Michael; Rothbaum, Barbara O.; Duncan, Erica J. – Learning & Memory, 2006
The purpose of this study was to analyze fear extinction and reinstatement in humans using fear-potentiated startle. Participants were fear conditioned using a simple discrimination procedure with colored lights as the conditioned stimuli (CSs) and an airblast to the throat as the unconditioned stimulus (US). Participants were extinguished 24 h…

Lavenex, Pierre; Lavenex, Pamela Banta – Learning & Memory, 2006
This experiment assesses spatial and nonspatial relational memory in freely moving 9-mo-old and adult (11-13-yr-old) macaque monkeys ("Macaca mulatta"). We tested the use of proximal landmarks, two different objects placed at the center of an open-field arena, as conditional cues allowing monkeys to predict the location of food rewards hidden in…
