Abstract
Two pigeons were trained to peck at a transilluminated disk. The training procedure caused the rate of pecking to increase as a function of the luminance of the disk. The results suggest that the relation between apparent magnitude of light and physical intensity is a power function.Keywords: PSYCHOLOGY, EXPERIMENTAL; VISUAL PERCEPTION
