Figure 4

Results of Experiment 3 (training over first five daily sessions). The graph shows the frequency of choice (means with SEM), in terms of number of attempts in correspondence of the corridors at the geometrically correct diagonal (C1 + C2) vs. the incorrect one (X1 + X2), during five consecutive daily sessions under a reference memory procedure, in a non-visual rewarded exit task, with unlimited exploration times. Black lines are referred to first choices for all fishes together, while green lines to total choices for all fishes (there was not difference among species). The improvement of performance in the rewarded exit task began to become apparent from the first days of training with extra-visual experience (i.e., through the lateral line and the sense of touch) of the environmental shape.
