Ontogenetic differences in variability on simple measures of learning: theoretical and practical implications.

abstract：:Three experiments with C57BL/10J mice examined the possible roles of cage size and simple motor practice as factors responsible for producing improved performance of animals reared in enriched environments. Neither factor was found sufficient to improve subsequent performance in a food-seeking task. Mice reared in fla...
