A computer touch-screen apparatus for training visual discrimination in rats

Article Abstract:

An operant conditioning apparatus that employes computerized touch-screen technology has finally been developed for the controlled testing of rats in different behavioral models. In the first test of the equipment's utility, an experiment showed how Sprague-Dawley rats learned to activate the touch screen only after the touch-screen panel was made slightly movable. The rats learned to visually discriminate after the food magazine and pellet dispenser were placed at the back of the chamber across the stimulus display and response window.

Evolution, behavior principles, and developmental systems: a review of Gottlieb's synthesising nature-nurture: prenatal roots of instinctive behavior

Article Abstract:

Gottleib's development psychobiology reexamines the importance of experimental analysis of behaviour in the life sciences. His experimental program demonstrates the critical function of the environment in the development of a species-typical behaviour, acceptance of probabilistic epigenesis and interaction of developmental genome-environment system.

Transitive responding in hooded crows requires linearly ordered stimuli

Article Abstract:

The description of the manner in which eight crows were taught to discriminate overlapping pairs of visual stimuli is presented. It is mentioned that the orderability of the postchoice feedback stimuli is important for crows' transitive responding.
