Behavioural tuning curve of latent inhibition.

<p>A. Mean performance (% visits without nose-pokes) on the first day of conditioning across pre-exposure frequencies for the conditioned visits (dark grey) and safe visits (mid grey). Small light grey dots represent the performance on the safe visits on the last day of the pre-exposure phase, for comparison. B. The same as in A for the conditioned visits only, in blocks of 6 hours (color coded) for the first 18 hours after the start of conditioning. C. Mean percentage visit without nose-pokes for conditioned (left) and safe (right) visits, in blocks of 6 hours for mice pre-exposed to 3335, 11218 or 13340 Hz. The lines with numbers are the number of conditioned (left) and safe (right) visits per time block for each of the three groups (color-coded as for dots) D. The same as in C, but removing from the analysis visits that were 1 second or less in duration. E. Mean d' values (left) and C (right) calculated using the same conditions as in C. F. As E but removing visits that were 1 second or less in duration.
