In a go/no-go discrimination procedure, four pigeons were trained to discriminate dynamic images of four human faces which were rotating around the y-axis from +67°to -67°. After completion of the training, transfer to static images at nine depth orientations (0°, ±23°, ±45°, ±67°, and ±90°) was tested in extinction. The pigeons showed excellent transfer to the static stimuli, but responses to the positive faces significantly decreased for novel views outside the range spanned by the dynamic stimuli. The findings suggest that the responses of the pigeons were based on two-dimensional properties of the faces seen in the training images rather than the three-dimensional properties of the human faces.
