The paper presents guidelines for training staff to implement positive reductive procedures to decrease undesirable behaviors of their retarded students and clients. Considerations relevant to all reductive procedures are briefly discussed in the first portion of the paper, while guidelines indigenous to positive reductive procedures are discussed…

Assesses the long-term retention of conditioned operant footkicks by three-month-old infants. Views a conditioning analysis as a logical means by which to bridge the gap between animal and adult human models of memory. (Author/RH)

Discusses the work of S. H. White, W. F. Overton and D. M. Baer. (MS)

Reviews the use of memory measures in the literature. Suggests problems with assumptions underlying Bogartz's proposed new measure. Responds to specific criticisms by claiming that Bogartz is critical of two measures that are not even used, unfamiliar with traditional conditioning theory, wrong in an assertion about traditional measures, and…

Responds to the general criticisms of Rovee-Collier, explaining a proposed new measure of infant memory in terms of four fundamental ideas earlier enumerated by Rovee-Collier and Shyi. Seeks to refute three of four specific criticisms made by Rovee-Collier, and admits a mistake related to the fourth criticism. (BC)

Proposes a minimal set of principles based on short-term and long-term memory mechanisms that can explain the major static and dynamic properties of operant behavior in both single-choice and multiresponse situations. The model predicts the major qualitative features of operant phenomena and suggests an experimental test of theoretical predictions…

Pigeons pecked left versus right keys contingent upon the color presented at 1 of those locations. Spatial-response latencies were shorter when the color appeared at the same location as the required response than at the opposite location. This Simon effect occurred when the stimulus on the alternative key was constant, varied from trial to trial,…

The ability of a reinforcer to maintain behavior decreases as a hyperbolic function of its delay. This discounted value can help explain impulsivity defined as the choice of an immediate, small reinforcer over a delayed, large reinforcer. Human operant studies using consumable reinforcers such as videos have found impulsivity with delays under 1…

To examine the effects on concurrent performance of independent manipulations of response-unit duration and number, 6 hens were exposed to concurrent second- order schedules of reinforcement. Each first-order operant unit required completion of a fixed-ratio schedule within the time specified by a fixed- interval schedule, with one further…

Contingencies of reinforcement specify how reinforcers are earned and how they are obtained. Ratio contingencies specify the number of responses that earn a reinforcer, and the response satisfying the ratio requirement obtains the earned reinforcer. Simple interval schedules specify that a certain time earns a reinforcer, which is obtained by the…

Describing the state of the science of ABA, this comprehensive handbook provides detailed information about theory, research, and intervention. The contributors are leading ABA authorities who present current best practices in behavioral assessment and demonstrate evidence-based strategies for supporting positive behaviors and reducing problem…

THE STUDY INVESTIGATED SOME OF THE RELATIONSHIPS BETWEEN A CHILD'S VERBAL BEHAVIOR AND ENVIRONMENTAL EVENTS NECESSARY IN ACQUIRING LANGUAGE. TWO TRAINABLE RETARDATES (FROM A GROUP OF SIX, AGED 3-6 TO 5) WITH A FUNCTIONAL VOCABULARY OF NO MORE THAN TWO OR THREE WORDS WERE SEEN INDIVIDUALLY IN 20- TO 30-MINUTE SESSIONS TWICE A WEEK DURING A 4-MONTH…

Psychologists, social workers, and school counselors are increasingly adding neurofeedback (NFT), a controversial alternative or complementary therapy to their treatment plans for patients with Attention Deficit Hyperactivity Disorder. NFT involves training the patient in self-regulation of brain wave patterns, employing a standard diagnostic…

As researchers continue to study creativity, a behavior analytic perspective may provide new vistas by offering an additional perspective. Contemporary behavior analysis began with B. F. Skinner and offers a selectionist approach to the scientific investigation of creativity. Behavior analysis contributes to the study of creativity by…

The study investigated the effect of object preference on the learning of signs by 12 severely and profoundly retarded children (4-7 years old). Signs were chosen that were two-handed, symmetrical, and abstract. Training of each sign consisted of 10 individual training sessions using operant techniques. Results revealed no differences in the…
