Discriminative Training on Two Different Luminance of Key Lights Not a few experiments on the discriminative training with pigeons were done over past several decades, and many researchers found that various factors relate to the results of discriminative training with pigeons. In a classical study by Heinemann and Rudolph (1963), they suggested that the geometric size of the stimulus influences on the efficiency of the learning by pigeons. There are several other factors pertaining to that efficiency of the learning. According to Sargisson and White (2001), the training delay is one of those factors. They found that the longer the training delay, the more sessions were required for all birds to reach the same level of response accuracy (Sargisson & White, 2001). In this discriminative training, therefore, the ring doves were trained with several different conditions in order to obtain some suggestions for to understand how they learn and what factors relates to the efficiency of their learning. What the doves learned in this operant conditioning was the discrimination of two different luminance of key-lights. Because many researches found that the doves had the reliable ability for discrimination of the intensity of lights, the results of learning depends on the long term memory of the subjects. Summarily, the purpose of this training was to know whether the doves can discriminate the differences of luminance of lights, and the factors which influences on their learning. Method Subjects Seven hungry ring doves (Streptopelia risoria) were tested. Six of them had previous experience on training to discriminate between the two red lights which had different luminosity. Before that, all of the doves were autoshaped to ... ... middle of paper ... ... an aspect of remembering. It might have been the reason why most birds had pretty high discrimination ratio. Therefore, it can be said that the results was reliable but the validity of this experiment might have been questionable. This training clearly showed the changes of the dove*s behavior but did not give clear factors for how they learned. That is to say, the possibility of that they just remembered what they had learned previously could not be rejected from this experiment. Bibliography: Heinemann, E. G., & Rudolph, R. L., (1963).
