The orienting response of hand and mother‐reared kittens who had been given daily doses of propylthiouracil during the first 50 days of life was tested at 60 days of age. Heart rate, respiration rate, and eye fixation on a visual stimulus were the measures used. A momentary light‐buzzer combination and a 30‐sec presentation of a rotating disc were the stimuli. There were no rearing or drug effects. Heart rate response was greater to the offset of the 30‐sec stimulus than to its onset. Respiration, the most sensitive measure, was speeded in the presence of a stimulus. Eye fixation, heart rate, and respiration rate curves during the 30‐sec stimulus were not parallel.
