Behavioural Studies of the Discrimination of Visual Orientation and Motion by the Goldfish
The discovery and investigation of stimulus analysing mechanisms at the cellular level in a variety of species has led quite naturally to a search for systematic relations between the responses of these analysers and the behaviour of the animals in whose brains they reside. In an early approach, Sutherland hoped to correlate variations in behaviour with variations in the proportion of different types of receptive fields present in the brains of different species (1963, p. 122). For example, animals with retinal, tectal, or cortical receptive fields which respond predominantly to stimuli oriented in the horizontal or vertical, as opposed to oblique, directions, should show corresponding asymmetries in behavioural discriminations of visual tilt, termed the oblique effect (Appelle, 1972). Or, animals in which cells predominate which respond maximally to stimuli which move across their receptive fields in a particular direction (Jacob-son and Gaze, 1964; Cronly-Dillon, 1964) should show behaviourally the effects of this organisation (Ingle, 1968).
