First, probes were more closely spaced around the standard in the temporal generalization task, and a narrower spacing of probes (i.e. a more difficult discrimination) has been proven to affect the decision stage of the timing process with a lower (i.e. more "strict") threshold in the most difficult discrimination [92], [93].
Results from the temporal generalization task helped establish the range of probes for the temporal expectancy task.
Second, repeated presentation of the standard (presented on each trial in the temporal generalization task only) could have reduced temporal variability, leading to a sharpened representation and a more efficient encoding of the target duration in reference memory [51].
While an overt estimate of the duration of an empty interval was required in the temporal generalization task, temporal regularities in stimulus presentation allowed for enhanced preparation and speeded motor performance in the temporal expectancy task.
Lesions of the dorsal striatum have been found to disrupt performance on the FIPP [6], and the firing rate of striatal neurones recorded during the performance of a temporal generalization task has been found to increase progressively towards a peak at the expected time of reinforcement [5].
Our explicit temporal generalization task required overt estimation of the duration of an empty interval bounded by visual markers, whereas our temporal expectancy task presented visual stimuli at temporally predictable intervals, which facilitated motor preparation thus speeding target detection.
A property generalization task is used, in which biological relations (birth origins) are pitted against adoptive relations.
Explicit perceptual timing was measured through a classic temporal generalization task, in which sensory inputs were timed in order to determine whether or not they were of equal duration.
We used a within-subject design to study a single group of patients with Parkinson's disease [early-to-moderate stage (Hoehn and Yahr stage: mean 1.69, SE 0.26)] in a generalization task introduced by Frank et al. (2004, 2007 b ) in three separate drug states (Fig. 1).
For example, it would be of interest to examine the pattern of Fos expression in rats trained on discrete-trials temporal generalization tasks [2].
