This study automated a visual discrimination system using a modified Sutherland jumping-stand box and an Apple IIe PC. Rats (n=8) were successfully trained, demonstrating the effectiveness of this automated behavioral apparatus.

Area of Science:

Behavioral neuroscience
Animal learning and behavior
Experimental psychology

Background:

Traditional visual discrimination systems can be labor-intensive.
Automation offers potential for increased efficiency and data precision.
The Sutherland jumping-stand box is a common apparatus for such studies.

Purpose of the Study:

To develop and validate an automated simultaneous visual discrimination system.
To assess the efficacy of a modified Sutherland jumping-stand box for automated training.
To evaluate the learning performance of rats in the automated system.

Main Methods:

Modification of a Sutherland jumping-stand box with lateral alleys and a digital interface.
Connection of the modified apparatus to an Apple IIe personal computer (PC) for automation.
