Two white Carneaux pigeons were trained to peck for mixed grain according to a multiple fixed-ratio 50, variable-interval 30-sec schedule of reinforcement. After the rate of responding stabilized, the pigeons were given weekly doses of diphenylhydant

To determine the effect of a negative discriminative stimulus on the response producing it, two pigeons were each studied in a three-key conditioning chamber. During alternating periods of unpredictable duration, pecking the center (food) key either

A case report of a retarded person teaching another retarded person in a residential setting is presented. The person teaching was trained to use graduated physical and verbal prompts to teach the printing and spelling of the alphabet and certain wor

Three pigeons were used to investigate the effects of a stimulus associated with the lower of two reinforcement frequencies on the response producing it. In a three-key chamber, pecking the center key produced grain on alternating variable-interval s

Using an observing procedure similar to Wyckoff's (1969) , two normal and two mentally retarded children were studied. The children were initially trained to earn pennies by pressing a rectangular key according to a multiple variable-interval extinct

Twelve rats were trained to produce food by barpressing according to a variable-interval schedule of reinforcement. When their rates of responding had stabilized, a conditioned suppression paradigm was implemented. After asymptotic suppression was ob
Pigeons were provided with three keys. Pecking the center key produced grain on a schedule that alternated at unpredictable times between a variable-interval component and extinction. On concurrent variable-interval schedules, pecking either side key

Summary.-The effect of stroboscopic photostimulation upon an institutionalized, mentally retarded, photoepileptic male was studied. Evidence of epileptiform activity was carefully monitored on a 16-channel electroencephalograph as a stroboscope was s

This study examined the effects of moderate, acute doses of diphenylhydantoin on the spontaneous motor activity of 30 rats. A dose of 30 mg/kg of the anticonvulsant drug produced an immediate, although short-lived (about 40 min.), suppression of this

The number of seizures for 50 chronically hospitalized patients during each of the four basic phases of the moon were recorded over a 5-yr.-period. The results indicated that phase of the moon was not related to the occurrence of seizures for years,
