Abstract:

Under conditions in which visual cues were virtually eliminated, the box turtle Terrapene c. carolina responded to angular acceleration with a deviation of the head graded according to the intensity and duration of the stimulus. The head-turning continued throughout an acceleration and a subsequent deceleration served to return the head toward its normal central position. Habituation did not occur, nor could a vestibular ocular nystagmus be recorded. A similarity was found between the turtle head turning response and the slow phase of ocular nystagmus of cat and of man. Author
