The ability of normal cats to perform delayed matching- and nonmatching-to-sample with trial-unique stimuli was investigated both in a modified Wisconsin General Testing Apparatus requiring manipulatory responses and in a Nencki-type testing room requiring locomotor responses. Cats trained in the WGTA learned the two tasks at about the same rate, on(More)
The current study tested spatial memory in 8 adult domestic cats using a spatial delayed response ("DR") memory task. Two existing different variants of that task were used by us in 8 adult domestic cats. One group of 4 cats was tested in the direct variant ("DDR"), while other group of 4 cats was trained to perform indirect variant ("IDDR"). DDR was based(More)
The role of the posterior parahippocampal area of the brain in spatial types of memory in conditions of one-trial visual perception of the positions of objects was studied by training eight cats to remember the spatial positions of either two different objects covering two of three feeders placed on a test tray (tests for the "object-place" association) or(More)
Memory for visual recognition in primates is at least partially mediated by the peripheral and entorhinal (i.e., rhinal) areas of the cerebral cortex. The roles of these structures in visual recognition in cats was studied by producing electrolytic combined lesions of the rhinal (perirhinal + entorhinal) areas in a group of cats trained in a modified(More)
