Abstract
Investigated the responses of rodents to monochromatic light. Two experiments were carried out with a color apparatus using the color discrimination method. The first was conducted on two animals - a white rat and a grey Belgian hare. Red and green lights were the two stimuli used. Food was given with red but not with green. Training experiments were conducted until they reached a high rate of accuracy in discrimination, after which a habit was formed. To test the problem of differential sensitivity, the second experiment was conducted. Results from three rats were analyzed. When the animals gave automatic responses to the first stimulus, the second stimulus was introduced. Concluded that long wave lengths stimulate the visual receptors of the rodents very slightly. Exp 2 showed that rats responded only to differences in intensity of monochromatic light. (PsycINFO Database Record (c) 2006 APA, all rights reserved)
