Abstract
Investigated the accuracy with which white rats localized sounds, and the extent to which absolute and relative intensity determined the accuracy of responses. Seven rats were made to form an association between the localization of a sound and food. In the control period, to determine factors responsible for accuracy of response, visual, olfactory, kinesthetic-tactual, and auditory controls were used. Tests on retention were also carried out. The results show that: (1) the rats were able to localize a noise (2) the association between such an accuracy of localization and food was established in 40 to 136 trials (3) responses were due to the auditory cues (4) the relative intensity of the sound to the 2 ears determined the accuracy of localization, and (5) there was evidence to show that if a rat was trained on an interrupted noise, it was disturbed in its accuracy of response by the substitution of a continuous noise.
