Influence of winning/losing experience on winning probability for individuals with lower/higher hormone levels. The decay of the effect of experience on the probability of winning for focal individuals with lower (< median) and higher (≥ median) levels of (A) pre-contest T and (B) pre-contest KT. This analysis was not carried out for individuals with lower and higher levels of pre-contest F as F had no significant influence on winning probability (Table 2). Pearson’s χ² tests were used to determine the significance of overall experience effects for each time-decay treatment/hormone-level group. For the treatments with significant overall experience effects, Fisher’s exact tests (2-tailed) were then used to test the significance of loser and winner effects separately by comparing the probabilities for the EL and the EW fish, respectively, to that for the EN fish (shown on tops of EL and EW bars, respectively). The sample size for each bar is presented on the bottom of the bar. ns P > 0.05; * P ≤ 0.05; ** P ≤ 0.01.
