Table 4: Behavioral data of all observation periods of experiment 2 taken together, presented as means � S.E.M. a,bWithin a row and variable, means without a common superscript differ (P < 0.05). Only significant P-values are shown. Means and S.E.M. are from the non-transformed data. Significant differences were obtained after analysis of the dichotomized data.
