Abstract

Video images of screensavers attract domestic chicks. This study identified their attractive attributes. One focal chick in groups of three was observed for 5 min daily on 10 consecutive days from 2 days of age. Chicks spent little time in the end zones of the home box in the absence of video stimulation (Experiment 1). Videos differing in one attribute were then presented simultaneously at opposite ends of the cage. Chicks spent longer near moving than still videos (Experiment 2), bright than dull videos (Experiment 3), coloured than black-and-white videos (Experiment 4), a complex “Fish” screensaver than a simple “Square” screensaver (Experiment 5), and a more complex cartoon than the Fish screensaver (Experiment 6). Repeated exposure increased approach and preferences were strongest for complex stimuli.
