Effect Experiment

Research on perceptual learning shows that the way stimuli are presented leads to different outcomes. The intermixed/blocked (I/B) effect is one of these outcomes, and different mechanisms have been proposed to explain it. In human research, it seems that comparison between stimuli is important, and the placement of a distractor between the pre-exposed stimuli interferes with the effect. Results from animal research are usually interpreted in different terms because the type of procedure normally used in animal perceptual learning does not favour comparison. In our experiments, we explore the possibility that a distractor placed between the to-be-discriminated stimuli may interfere with the perceptual learning process in rats. In Experiment 1, two flavoured solutions are presented in an I/B fashion, with a short time lapse between them to favour comparison, showing the typical I/B effect. In Experiment 2, we introduced a distractor in between the solutions, abolishing this effect. Experiment 3 further replicates this by comparing two intermixed groups with or without distractor. The results replicate the findings from human research, suggesting that comparison also plays an important role in animal perceptual learning.

Kinesthetic Feedback

Hooded rats were pre-exposed to circles and triangles in an otherwise visually sparse environment where opportunity to manipulate the forms was varied for the early experience groups. Although early experience with these stimuli enhanced their later discriminability over that shown by control animals who received no early experience, opportunity to manipulate the forms produced no additional gain in perceptual learning relative to Ss not allowed to manipulate the pre-exposed shapes. The findings restrict the generality of the tactual-kinesthetic feedback hypothesis.
