A REVIEW OF POSITIVE CONDITIONED REINFORCEMENT1

RT Kelleher, LR Gollub - Journal of the Experimental Analysis …, 1962 - Wiley Online Library
This review critically analyzes experimental data relevant to the concept of conditioned
reinforcement. The review has five sections. Section I is a discussion of the relationship between …

CONDITIONED REINFORCEMENT IN SECOND‐ORDER SCHEDULES1

RT Kelleher - Journal of the Experimental Analysis of Behavior, 1966 - Wiley Online Library
Pigeons responded under a schedule in which food was presented only after a fixed number
of fixed‐interval components were completed. Two such second‐order schedules were …

Fixed-ratio schedules of conditioned reinforcement with chimpanzees

RT Kelleher - Journal of the Experimental Analysis of Behavior, 1958 - ncbi.nlm.nih.gov
RESULTS The individual rates of responding were bi-valued; that is, S was either not
responding (pausing) or responding at a high, stable rate (the running rate). Figure 1 shows …

Arterial hypertension in the squirrel monkey during behavioral experiments

JA Herd, WH Morse, RT Kelleher… - American Journal of …, 1969 - journals.physiology.org
METHODS Twenty-one male squirrel monkeys (600-1,000 g) were used to obtain normative
data, and six of them later were trained under two operant-conditioning schedules. The …

Behavioral induction of arterial hypertension and its reversal

…, JA Herd, WH Morse, RT Kelleher - American Journal of …, 1969 - journals.physiology.org
METHODS Two hundred seventy-three experiments were performed in three squirrel
monkeys (600 to 900 g). The techniques for measuring arterial blood pressure and training the …

Discrimination learning as a function of reversal and nonreversal shifts.

RT Kelleher - Journal of experimental psychology, 1956 - psycnet.apa.org
The first experiment reported is a comparison of reversal and nonreversal shifts: the second
eliminates the partial reinforcement following a nonreversal shift. In Exp. I found that the …

Observing responses in pigeons

RT Kelleher, WC Riddle, L Cook - Journal of the Experimental …, 1962 - Wiley Online Library
Pigeons were trained on an observing‐response procedure in which periods of VR 100 and
EXT alternated unpredictably during a white light (mixed stimulus). During VR 100, …

Stimulus functions in chained fixed‐interval schedules

RT Kelleher, WT Fry - Journal of the experimental Analysis of …, 1962 - Wiley Online Library
Pigeons were required to complete three successive fixed‐interval components to obtain
food. When the same exteroceptive stimulus was correlated with the three components, …

Schedules of conditioned reinforcement during experimental extinction

RT Kelleher - Journal of the Experimental Analysis of Behavior, 1961 - ncbi.nlm.nih.gov
RESULTS Figure 1 presents the results with one bird during the first two experimental extinction
sessions. In the first session (Frame A), the magazine sound initially occurred on a DRP …
