The researchers found that the length of the line affected the pigeons' discrimination of line duration, and the duration of the line affected the pigeons' discrimination of line length. Discrimination of two auditory durations by pigeons experiment 1 the development and for examining duration discrimination in. Pigeons rapidly acquired a discrimination between 40 pictures containing is especially clear in experiments in which duration of each presentation was 30 sec . Pigeons were trained to discriminate the duration of a stimulus one response in a psychophysical choice situation was reinforced, given the immediately prior presentation of a stimulus duration in one class of durations called short durations, and the other response was reinforced given the immediately prior presentation of a stimulus duration .
Temporal discrimination in pigeons duration discrimination may have less ecological validity in a slot machine analog than categorical discrimination, but we do not view this as a critical .

Pigeon short-term memory: the effects of temporal discrimination theory 38 effects of illumination and intertrial duration 55 main experiment method 61 . Characteristics of the discrimination of brief visual stimuli were examined in three pigeons by a psychophysical procedure in a two-choice discrimination task, the difference between the duration to be compared and the standard duration, which yielded 75% correct choice responses, was determined as .
Pecking of the lighted key was reinforced only after the shortest or, in a second experiment, the longest interval that the key was dark the pigeons were able to discriminate the duration of the dark interval. The researchers found that the length of the line affected the pigeons’ discrimination of line duration, and the duration of the line affected the pigeons’ discrimination of line length this interplay of space and time paralleled research done with humans and monkeys and revealed the common neural coding of these two physical dimensions. The pigeon as art critic the pigeons in this experiment were taught that pecking at the “good” set of pictures would yield a grain reward, whereas pecking at the “bad” set of pictures .

Temporal discrimination in pigeons in a second experiment, the longest interval that the key was dark duration discrimination may have less ecological validity in a slot machine analog .
Mean proportion of responses to the long key color during control (top row) and morphine sessions (lower rows) as a function of sample duration for each pigeon during the temporal-discrimination component. It is possible that infants might discriminate among launching events by using stimulus features like those that controlled our pigeons' behavior: the overall duration of the interaction, the rate of object motion, or the initial or ending positions of the interacting objects (also see oakes & cohen, 1990) discrimination tests similar to those .
