Abstract

From Day 2 to Day 4 of life, chicks were fed daily in a large enclosure with 2 identical food caches, each filled with a different type of seed. On Day 5, binocular and monocular chicks were fed in their home cages 1 type ofseed exclusively for 30 min. At test, soon after this devaluation phase, both binocular and right-eyed chicks chose the food caches containing the seeds that had not been devalued; in contrast, left-eyed chicks did not show a clear choice. Experiments revealed that the asymmetry was not due to lackof motivation, worse spatial memory, or inability to remember the consequences of devaluation by left-eyed chicks. Results suggest that young chicks can form declarative-like memories of the content of food caches. However, chicks using their left eye (which provides a supply mainly to the right hemisphere) failed to integrate memory of the content of food caches with memory of the consequences of devaluation.
