Recently, we reported that practice facilitates the expression of the behavioral asymmetry in rats at individual and population levels. In the present study we investigated the side preference in the performance of four different tasks during 10 successive days. The practice increased individual laterality and internal consistency in all tasks. In addition, practice facilitated the expression of marked population laterality in two tasks (78.1% and 63.3% for right bias). The influence of… CONTINUE READING
