Interaction of set and awareness as determinants of response to verbal conditioning.

The utility of an operant conditioning model to psychotherapy was evaluated by studying the definition of the situation given S and S's focus on E's behavior. Instructions induced either a positive or negative set, identifying a story telling task as a test of empathy or personal problems. Awareness was induced in ? of the Ss by calling attention to E's reinforcement "mm-hmm." 12 undergradate students served as Ss in each of the 4 experimental groups. Positive set-Aware Ss increased use of emotional words, while Negative set-Aware Ss decreased use of emotional words. The results were interpreted as evidence that awareness can either facilitate or inhibit conditioning, depending upon S's set. (26 ref.)

Conditioning of verbal behavior as a function of awareness, need for social approval, and motivation to receive reinforcement.

This investigation evaluated the effects of awareness, need for social approval, and motivation to receive reinforcement on verbal conditioning. 61 male college students were reinforced with "good" for constructing sentences beginning with "I" or "we." Awareness and reinforcement motivation were assessed by an intensive postconditioning interview; need for social approval was measured by the Marlowe-Crowne Social Desirability scale. Ss aware of a correct response-reinforcement contingency gave more "I" and "we" sentences than Unaware Ss, who showed no evidence of learning. Aware Ss motivated to receive reinforcement gave more "I" and "we" sentences than unmotivated Aware Ss. Contrary to expectation, need for approval was not related to Ss' reinforcement motivation or performance. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Effects of operant level, interview with experimenter, and awareness upon verbal conditioning of chronic schizophrenics.

The present research attempted to (a) cross-validate N. D. Vestre's (1961, 1965) findings that medium-operant-level pronouns can be conditioned by "good" in a chronic schizophrenic population, (b) test whether or not high-operant-level pronouns can be conditioned by "good" in a chronic schizophrenic population, and (c) compare the conditionability of high-operant-level with that of medium-operant-level pronouns. It was hypothesized that schizophrenics would be more conditionable following a brief, friendly, personal interview than in the absence of any preconditioning interview. It was expected that awareness of the response-reinforcement contingency would favor conditioning. Both the operant level and interview with experimenter variables were investigated to see whether or not either differentially affected (a) the number of aware Ss and (b) the performance of aware Ss. "Good" functioned as a reinforcer for about 1/4 of the Ss in this study. The most important factor contributing to performance was awareness of the response-reinforcement contingency. Also, reinforcement tended to be more effective when Ss had no (instead of a S-min) preexperimental interview with E. Medium-operant-level pronouns were conditionable, and results of conditionability comparisons between high- and medium-preference pronouns depended upon how performance was measured. The negligible conditionability of high-preference pronouns was discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Commitment to social deprivation and verbal conditioning.

Control Ss who experienced high prior deprivation of a reinforcing stimulus (approval) responded more with a reinforced response in a verbal conditioning situation than Ss less deprived. Other Ss committed themselves to undergoing postexperimental deprivation of social reinforcement after the same high prior social deprivation. A model suggested by dissonance theory predicted that such Ss who committed themselves for lower rewards would experience greater dissonance; the greater the dissonance, the more could Ss justify their decisions and reduce dissonance by reducing their motive for social reinforcement, consequently behaving in the conditioning situation as Ss who had low motivation for social reinforcement. As expected, experimental Ss in the High Dissonance condition who committed themselves for low reward ($1.00) responded less to social reinforcement, i.e., they showed a smaller increase in response strength of emission of verbal behavior than Control Ss or Low Dissonance Ss who committed themselves for high reward ($5.00).

Verbal conditioning as a function of experimenter characteristics.

An investigation was conducted to test the hypothesis that differences in the characteristics of experimenters can lead to differential learning effects when the experimental session involves verbal conditioning without awareness. "Two experimenters of different sex and markedly different height, weight, age, appearance, and personality ran separate groups of Ss." Results indicated that "the response 'Good' was reinforcing for the class of behavior consisting of the use of hostile words in sentences. In addition, it was found that the rates of learning for the Ss of the two experimenters differed significantly, with a steeper slope for the female experimenter's group."

Hypotheses and habits in verbal "operant conditioning.'

The traditional explanation of experiments related to conditioning of verbal behavior in terms of operant conditioning, i.e., learning without awareness, was questioned. It was hypothesized that such conditioning to cues given by E might be based on S's awareness of the cue and assumed meaning of such a stimulus. 2 experiments were performed, 1 where plural nouns were reinforced, and a 2nd to test the generalization of this acquired pattern on a word association test. The usual findings re: conditioning of plural nouns was replicated and there seemed to be a carry-over of the set to the word association test. However, some Ss seemed to be aware of the meaning of such a reinforcer as "um-hm." Moreover, response set was also seen to affect conditionability.

Studies of the conditioning of verbal behavior.

"Thirty-one articles reporting studies of the conditioning of verbal behavior were reviewed in terms of setting, verbal responses, reinforcement stimuli, populations, controls, length of sessions, relationships to personality variables, results, and awareness. The majority of the studies report positive results with the use of generalized conditioned reinforcers such as good and mmm-hmmm. The studies reviewed demonstrate that general principles of learning can be fruitfully applied to the experimental analysis of verbal behavior." 108-item bibliography.

Effects on avoidance performance of vagal stimulation during previous fear conditioning in rats.

Attempted to determine, from experiments on 5 groups of 10 male albino rats each, whether parasympathetic stimulation given coincidentally with electric shock in a fear-conditioning situation would alter later performance on an avoidance conditioning task. 10 Ss were implanted with a small chronic electrode around the cervical vagus. During preconditioning, consisting of 8 trials of tone followed by inescapable shock, 1 group of Ss received stimulation of the vagus at the time foot shock was delivered. During subsequent avoidance conditioning, these Ss performed the avoidance task significantly better than Ss that received the same preconditioning without vagal stimulation and as well as Ss that had received no preconditioning shock trials.

A laboratory adaptation of the conversational procedure for the conditioning of verbal operants.

In an attempt to adapt the conversational procedure initiated by Verplanck to the conditioning of verbal operants under laboratory conditions, an experiment was performed with each of 49 Ss who were unaware of the true nature of the experiment. While supposedly merely waiting with another S, who was in reality the investigator's assistant, their responses during their conversations with the assistant were subjected to a variety of reinforcing and deterring stimuli. The attempt was made to condition opinion, information, and question operants, with positive results being achieved for the opinion and information responses, while negative results were obtained for question operants. Under extinction conditions there was a decrease of all these operants. The results are interpreted as supporting the hypothesis that verbal operants can be conditioned in conversations which are contrived in laboratory settings.

Personality and verbal conditioning effects.

In line with the studies on the conditioning of verbal behavior and their reference to psychotherapy, the present study investigates the effects of Autonomy (as measured by the EPPS) upon verbal conditioning. The hypothesis was made that Autonomy would interfere with susceptibility to verbal conditioning. Ss were interviewed, being asked to talk about themselves; E reinforced (said "um-hmm" and nodded head) under 3 conditions, viz., when S made positive self-statements, negative self-statements, or reinforced randomly throughout the interview. The results indicate that by responding selectively, an interviewer can influence the verbalization of S; in this instance, reinforcement was effective in producing a significant effect on positive self-statements, but not negative ones. Meaning of results are discussed with relation to other research and an attempted formulation. From Psyc Abstracts 36:01:3CJ41B. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The effect of negative verbal cues upon verbal behavior.

Research which investigated the capacity to modify behavior, starting from the framework of Skinner's operant conditioning paradigm and utilizing verbal behavior, was found to have primarily explored the effect of positive secondary reinforcement. The present investigation explored the effect of a negative verbal cue presented under different schedules of reinforcement upon verbal behavior. Ss (male VA psychiatric patients) responded to projective techniques. The E varied the frequency of negative verbal reinforcement defined as "unh unh." The hypothesis that such a negative reinforcement would depress verbal behavior was substantiated, with a periodic schedule of reinforcement being more effective.

Expressive movements, warmth, and verbal reinforcement.

"In order to determine the effects of the experimenter's warmth and coldness upon verbal conditioning in a free association task, 69 subjects were randomly assigned to four experimental groups in a factorial design. Warmth and coldness were defined in terms of expressive movements of posture, glance, facial expression, and finger activity. Analysis of the results showed that the total number of words was significantly affected by the expressive movements and verbal reinforcement, but was not significantly influenced by verbal reinforcement alone."

The effect of the schedule of reinforcement on operant conditioning of a verbal response in the autokinetic situation.

The autokinetic effect was employed to compare the effect of 2 different schedules of reinforcement on verbal behavior. One group of Ss was given 20 reinforcements of "Right" under a regular reinforcement schedule for emitting verbally the estimate designated as the response. A second group was given similar reinforcement under a variable interval schedule. The regular reinforcement group reached the criterion of extinction in 10 to 35 verbal emissions while no S in the variable interval group extinguished within 10 to 80 verbal emissions. 15 references.

Verbal conditioning of two response classes: Some methodological considerations.

The capacity to condition verbalizations of an interviewee was seen to be related to S's awareness of what was going on but independent of such variables as the age, sex, vocabulary level, (Taylor) anxiety level, and word rate of Ss. Specific content could be successfully conditioned, particularly those words which related to people; such words as plural nouns were unaffected by the reinforcement procedures.

GSR reactivity as a function of anxiety, instructions, and sex.

"GSR conditioning and extinction measures were obtained on 120 college Ss in a factorial experimental design in which 12 treatment groups were divided into 2 sex groups, 3 instruction groups, and high- and low-anxiety groups. The 3 instruction groups were given 3 different kinds of instruction designed to be: (a) apprehension arousing; (b) neutral; and (c) reassuring." Male Ss showed less conditioning when given reassuring instructions; female Ss showed the least conditioning with the apprehension-arousing instructions. Females showed greater GSR reactivity than males in all phases of the experiment. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Effects of a positive social reward upon a verbal avoidance response.

In investigating the effect of reward upon the acquisition and extinction of avoidance response, a word association task was presented to 90 Ss for 8 conditioning and 12 extinction trials. During conditioning, associations to preselected words were punished on Trial 1 and whenever S repeated them. There were 3 acquisition groups: 1 received the above training, the 2nd also received reward for substitute associations, and the 3rd obtained reward during the 2nd ? of acquisition only. Each acquisiton group was divided into 2 extinction subgroups: 1 received neither reward nor punishment while the 2nd was rewarded for avoiding. Results indicated that reward hastened acquisition and delayed extinction of avoidance responses, thus confirming hypotheses regarding the concept of secondary gain.

Interrelationships among individual difference variables, behavior in psychotherapy, and verbal conditioning.

3 variables studied were S's score on personality inventory scales, therapists' rating of S's behavior in the psychotherapy situation, and Ss performance in a verbal conditioning situation. The Ss were 60 neurotic and psychotic patients, 58 of whom were men; the Autobiographical Survey was the Personality inventory. With regard to the Autobiographical Survey, high scores on the Test Anxiety and Lack of Protection scales were associated with higher levels of verbal conditioning; high Defensiveness scores with poor verbal conditioning. Patients rated by their psychotherapists as being very compliant were found to perform in the verbal conditioning at a higher level than patients rated as being relatively noncompliant.

Need for approval and the conditioning of verbal hostility in asthmatic children.

A verbal operant conditioning paradigm was employed to test the hypothesis that the differential conditionability of hostile and neutral verbalizations is related to the need for social approval. Approval-motivated Ss were generally more effectively conditioned than relatively nonapproval-oriented children. Contrary to predictions, approval-motivated children were more effectively conditioned to hostile than to neutrally toned verbalizations. Nonapproval Ss viewed hostile responses as having minimal reinforcement value. These results were closely related to degree of awareness of the reinforcement contingencies. (22 ref.)

Studies in efficiency: Verbal conditioning as a function of degree of task centering. A replication.

The present study is an approximate replication of an experiment by Letchworth and Wishner (1962). Its substantive purpose was to test the effects on verbal conditioning of self- and other centered (SC and OC) instructions in interaction with 2 types of task orienting instructions. From the concept of efficiency it was predicted that there would be a significant interaction of the following form: SC Ss would have a relatively higher rate of conditioning than OC Ss under relaxed instructions, while the reverse would be true under problem instructions. Procedural changes from the previous study were incorporated in order to increase experimental control. A significant interaction supported the experimental hypothesis and duplicated the results of the previous study. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
