Psychology students frequently have misconceptions of basic concepts in operant conditioning. Prior classroom observations revealed that most students defined positive reinforcement as reward and equated negative reinforcement and punishment. Students also labeled positive reinforcement as rewarding good behavior and negative reinforcement as…

Michael (1975) reviewed efforts to classify reinforcing events in terms of whether stimuli are added (positive reinforcement) or removed (negative reinforcement). He concluded that distinctions in these terms are confusing and ambiguous. Of necessity, adding a stimulus requires its previous absence and removing a stimulus its previous presence.…

Memories can have different strengths, largely dependent on the intensity of reinforcers encountered. The relationship between reinforcement and memory strength is evident in asymptotic memory curves, with the level of the asymptote related to the intensity of the reinforcer. Although this is likely a fundamental property of memory formation,…

Four treatment procedures were evaluated for effectiveness in reducing self injurious behavior (SIB) of 22 severely handicapped students. Treatment procedures included contingent restraint, reinforcement withdrawal, differential reinforcement of incompatible behavior, and ommission training (rewarding the S for not emitting the SIB response).…

The effectiveness of positive and negative evaluative comments for children's learning was assessed in a two-choice discrimination task. Results indicate that negative comments after incorrect responses greatly facilitated learning while positive comments after correct responses had little effect. To explain the findings, a naturalistic analysis…

A series of five experiments revealed a striking point-for-point correspondence between the effects of a reinforcer in escape conditioning and the effects of competition cessation in competitive performance. (Author/MP)

Results of an experiment with 6-month-old infants showed that response-independent auditory-visual reinforcement can elicit learned responses and that action-consequence learning in infants may consist of a combination of elicitation and conditioning. (Author/JMB)

A total of 30 infants with an average age of 83.4 days were trained for one l8-minute, two nine-minute, or three six-minute sessions separated by 24-hour intervals in order to investigate long-term retention of operant foot kicking acquired in the mobile conjugative reinforcement paradigm. (Author/CI)

A base rate of deviant behavior was obtained for the eight most disruptive children in a third grade adjustment class. In a token reinforcement program, the children received teacher's ratings, which were exchangeable for reinforcers such as candy and trinkets. With the introduction of the token reinforcement program, an abrupt reduction in…

The purpose of this study was to investigate the efficacy of a behavior modification method for remediation of reading skills with ten primary grade students enrolled in a sixteen week program. Ten elementary school teachers enrolled in a graduate diagnostic and remedial reading course received eight hours of instruction, including the collection…

The use of operant techniques in the classroom, especially with slow learners, was investigated, and several types of reinforcement were compared. Subjects were 129 fourth graders enrolled in a middle school in a disadvantaged rural Florida community. The subjects were stratified by race, sex, and homeroom and were randomly assigned to one of five…

One hundred twenty-eight preschool boys were subjects in a 4x2x2 factorial design to investigate the change in reinforcer efficacy as a function of prior stimulus exposure. The factors were: (1) amount of repetition, 5, 25, 45, or 65; (2) reinforcer, good or bell; and (3) satiator, good or bell. Two additional groups were run as control groups to…

The primary goal of this study was to assess the effectiveness of two distinctly different techniques, restatement and interpretation, on a criterion variable of counseling. The study objectives were: 1) to operationally define these two classes of counselor response and train two counselors to produce them upon cue in a counseling session, using…
