Behavioral Analysis of Social Effects on the Problem‐Solving Ability in the House Mouse

Abstract

AbstractThe effects of the social context on the problem‐solving ability in the house mouse was evaluated by means of a puzzle box containing food, which could be opened by rotating a revolving door. The aim of the study was to clarify which mechanisms of social learning promote the acquisition of this complex motor skill. Young mice were exposed to the puzzle box in the presence of (i) demonstrators opening of the puzzle box; (ii) adults unable to open the puzzle box; and (iii) adults confined in one part of the cage and not manipulating the puzzle box. Results of the detailed analysis of the sequence of behaviors showed that (i) young mice successful in opening the puzzle box did not copy the sequence of actions performed by demonstrators; and (ii) the presence of adult conspecifics in proximity of the problem apparatus increased the rate of success of young mice. Results suggest that trial‐and‐error learning, social exposure and stimulus enhancement all play a role in the acquisition of the opening ability.
