“…It is apparent that the stimulus effects operate both between Ss with novelty controlled and within Ss. There is close agreement between the results of Experiment 3 and those obtained by Dutch (1969) with chicks in a similar situation. CONCLUSION The resul ts of these three experiments support the hypothesis that the effects of increasing the complexity of visual stimuli produces behavior which conforms to an inverted U-shaped function, demonstrating an optimum level of stimulus complexity in the approach behavior of rats.…”

“…For example, rhesus monkeys worked harder to view complex rather than simple projected images (Humphrey, 1972). More specifically, chicks approached cards with complex patterns more than plain or simply patterned ones (Berryman, Fullerton, & Sluckin, 1971;Dutch, 1969). Similarly, televised images of screensavers were more attractive to chicks than blank, illuminated monitors (Jones et al, 1996.…”

“…We examined chicks' responses to simultaneously presented video images of simple (S, bouncing green square) and more complex (F, fish) screensavers. Dutch (1969) defined complexity as "the number of elements constituting each stimulus". This definition was applied here; the screensavers used differed in the variety of colours and moving objects as well as in the size and the number of images on screen.…”

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.

Factors affecting the development of filial preferences in chicks were investigated. Four groups of chicks were hatched and maintained in darkness. When the chicks were 20-hr old, three of these groups were exposed to an overhead light ("primed") for .5 h. When 24-hr old, all groups were placed in running wheels for 2 hr. While in the wheels one group was exposed to a visually complex pattern, one group to diffuse overhead light, and the remaining two groups (one primed and one not primed) were in darkness. All chicks were then returned to a dark incubator until their preference for a red box or a stuffed jungle fowl was measured in a simultaneous choice test either 2 hr (Test I) or 24 hr (Test II) later. At Test I the chicks which had been exposed to the complex visual pattern showed a significant preference for the fowl. Chicks in the other groups showed no preference. At Test II all groups showed a significant preference for the fowl. The results of a second experiment suggested that the later emerging preference was related to the chicks experience in the running wheel. It was concluded that the preference for the fowl will develop in entirely dark-reared chicks that are allowed a period of time in a running wheel, but that this preference will appear earlier in chicks which have had experience of a complex visual pattern.
