Proportion of correct following responses for each dolphin during the same-clothing condition. Left panel change in performance across eight-trial blocks (the second block did not consist of eight trials; therefore, the correct following responses/total trials ratio is presented near to the 1 data points). Right panel proportion of correct responses averaged across sessions. Numbers at the bottom of each bar indicate the ratio between correct following responses/total trials. E Eagle, Q Quick, T Tino.
