Acquisition and reversal in the procedural T-maze.

<p>In the procedural T-maze mice are trained to reach a platform on one side of the maze. After they perform correctly 6 out of 8 trials in two consecutive days, the platform position is reversed and mice are trained under the new rule. A: The proportion of mice that reached criteria during the acquisition (maximum 8 days) shows that there were no deficits in the 16p11.2 df/+ mice but Cntnap2 -/- mice learned the task faster; B: during reversal (6 days maximum) there were no deficits either. Note the reversal data for Cntnap2 WT mice are identical to that of the Cntnap2 -/- mice. Data shown are proportions of mice that started the task (Genotype Factor, Survival Analysis, Chi Square: **p < .01).
