Figure 3. Improvement in behavioural thresholds as a result of learning for participants trained on in-phase dots (A) and counter-phase dots (B).

Each training session consisted of 400 trials. If 75% correct or better was achieved during a training session, the angular deviation was decreased by 1° for the subsequent training session. For two participants trained on counter-phase dots, the angular deviation was increased for two sessions mid-training in an attempt to facilitate additional learning. Each line represents an individual participant.
