Detection sensitivity for target flanked by collinear flankers, before (pre) and after (post) training.

<p>Mean d-primes as a function of the target-to-flanker distances (λ) for the target flanked by collinear flankers. Data refer to Gabors with a spatial frequency of 4 cpd. Filled circles refer to pre-training measurements, and open circles refer to post-training measurements. Error bars ±1 s.e.m.
