Table 4. Effects of Isolation Rearing on Non-Target Win-Stay and Lose-Shift Ratios in the Within-Session Probabilistic Learning Task.

During the initial learning phase, there was a significant main effect of Day on non-target win-stay ratio and a trend (p = 0.091) towards a main effect of Rearing on non-target lose-shift ratio, but no clear patterns explaining these findings could be identified. No other effects on non-target win-stay and lose-shift ratios were seen during the initial learning phase. Likewise, no effects of Day or Rearing on non-target win-stay and lose-shift ratios and no interactions were found during the reversal-learning phase
