Résumé

Backward adaptation Control 1 st Phase 3 rd Phase 1st Phase 3rd Phase Gain 0.99 ±0.05 0.80 ±0.05 0.97 ±0.05 0.99 ±0.05 Latency 235 ±97 205 ±40 259 ±74 218 ±44 Phase 1 similar to Phase 3 for control group Saccadic parameters and difficulty of the task are stable in the control group. Overall, PSE slightly increases when saccadic amplitude decreases. An increase in PSE indicated that the size of the comparison disk in the third phase has to be larger to become perceptually equal to the standard, compared to the first phase. Psychometric functions for #21 from Backward adaptation group (left) and for #48 from Control group (right). Error bars represents confidence interval at 95%. We observed a shift of the PSE to the right for #21 and an overlap of the PSEs for #48 Paired t-test : * p<.05, ** p<.005, *** p<.001 ns p>0.5
