Successive visual reversal learning in rats as a function of amount of training per reversal and reduced spatial cues

An experiment is reported which examined the effects of varying amounts of training per reversal over successive brightness discrimination reversals in rats, in a situation which reduced visual cues to spatial position. The results were similar to those of studies showing that amount of training affects successive reversal improvement on spatial problems but no differences were observed as a result of varying the cues for spatial position. The latter finding failed to confirm the result of a recent experiment in which a learning criterion was employed rather than a fixed-trials procedure.
