Figure 2. Effects of Intensive Mental Training on the Attentional Blink.

(A) T2 accuracy at time 1 (black bars) and the improvement (red bars) or deterioration (blue bars) in T2 accuracy at time 2, for each participant, separately for the short and long T1–T2 interval.

(B) Average T2 accuracy (plus standard error) for each session, T1–T2 interval, and group (at-chance participants excluded). Note that both groups showed an attentional blink at time 1: lower T2 accuracy at short- compared to long-interval trials. Note further that, as predicted, the practitioner group (Pract) showed a significantly larger reduction in attentional-blink size over time than the novice group (Nov).
