Description
Four experiments examined whether food-storing scrub jays remember when and where they cached different foods. The scrub jays cached and recovered perishable and nonperishable foods in visuospatially distinct and trial-unique cache sites. They rapidly learned to avoid searching for foods that had perished by the time of recovery, while continuing to search for the same foods after shorter retention intervals when the foods were still fresh. The temporal control of searching at recovery was also observed when the familiarity of cache sites did not provide any information about the time of caching and when the same food was cached in distinct sites at different times. The authors argue that the jays formed an integrated memory for the location and time of caching of particular foods.(PsycINFO Database Record (c) 2016 APA, all rights reserved)
