THE USE OF PROMPTS TO ENHANCE VICARIOUS EFFECTS OF NONVERBAL APPROVAL

The effect of nonverbal teacher approval (physical contact in the form of patting approvingly) delivered to target subjects on the attentive behavior of adjacent peers was examined in a special-education classroom. In a reversal design, two pairs of moderately retarded children were exposed to nonverbal approval, with only one subject in each pair receiving approval. In different phases, nonverbal approval was delivered alone or in conjunction with a verbal prompt directed to the adjacent peer or to the class as a whole. The prompt was designed to make salient the target subject's attentive behavior and the nonverbal reinforcing consequences that followed. Providing contingent nonverbal approval alone consistently altered attentive behavior of the target subjects but did not alter the attentive behavior of adjacent peers. However, accompanying nonverbal approval with a verbal prompt did increase attentive behavior of nonreinforced peers.     

THE IMPACT OF APPLIED BEHAVIOR ANALYSIS ON DIVERSE AREAS OF RESEARCH1

The impact of applied behavior analysis on various disciplines and areas of research was assessed through two major analyses. First, the relationship of applied behavior analysis to the general area of “behavior modification” was evaluated by examining the citation characteristics of journal articles in JABA and three other behavior-modification journals. Second, the penetration of applied behavior analysis into diverse areas and disciplines, including behavior modification, psychiatry, clinical psychology, education, special education, retardation, speech and hearing, counselling, and law enforcement and correction was assessed. Twenty-five journals representing diverse research areas were evaluated from 1968 to 1974 to assess the extent to which operant techniques were applied for therapeutic, rehabilitative, and educative purposes and the degree to which methodological desiderata of applied behavior analysis were met. The analyses revealed diverse publication outlets for applied behavior analysis in various disciplines.     

Psychological dynamics and self-perceptions of vasectomy candidates.

Growing concern with population control has focused attention on various methods of contraception including vasectomy. Psychological research on this topic is scant, however. In this study, 9 vasectomy candidates who were undergoing the operation were compared to 9 husbands whose wives were about to have a tubal ligation. Their responses on the Marlowe-Crowne Social Desirability Scale and the Adjective Check List were compared. Most of the data showed no significant differences except on one scale of Counseling Readiness. The results, and others, indicate that vasectomy candidates may have a tendency to deny the anxiety connected with the operation due to its irreversible nature.     

Psychopathology scale of the Hutt adaptation of the Bender-Gestalt Test: reliability.

The test-retest reliability of the Hutt Adaptation of the Bender-Gestalt test was explored with a population of 40 process schizophrenics over a two-week interval. The total Psychopathology Scale Score was found to have high retest reliability for both male and female patients (rho = .87 for males and .83 for females). Moreover the three major components for the Scale were found to have high reliability, and fairly high reliabilities were obtained for patients scoring high as well as low on the Scale. Interjudge reliability was also found to be very high (rho = .895), confirming previous studies in this respect. On these grounds, the Scale offers promise both for clinical and research purposes.     

Attribution versus persuasion as a means for modifying behavior.

The present research compared the relative effectiveness of an attribution strategy with a persuasion strategy in changing behavior. Study 1 attempted to teach fifth graders not to litter and to clean up after others. An attribution group was repeatedly told that they were neat and tidy people, a persuasion group was repeatedly told that they should be neat and tidy, and a control group received no treatment. Attribution proved considerably more effective in modifying behavior. Study 2 tried to discover whether similar effects would hold for a more central aspect of school performance, math achievement and self-esteem, and whether an attribution of ability would be as effective as an attribution of motivation. Repeatedly attributing to second graders either the ability or the motivation to do well in math proved more effective than comparable persuasion or no-treatment control groups, although a group receiving straight reinforcement for math problem-solving behavior also did well. It is suggested that persuasion often suffers because it involves a negative attribution (a person should be what he is not), while attribution generally gains because it disguises persuasive intent.     

Trigeminal nerve and eating in the pigeon (Columba livia): neurosensory control of the consummatory responses.

Electrophysiological, neurobehavioral, and cinematographic techniques were used to study the role of the trigeminal nerve in the neurosensory control of eating. Analaysis of single-unit data recorded in the pigeon's trigeminal ganglion indicates that the trigeminal nerve provides somatosensory inputs from the oral region that signal the location and movement of food and monitor the extent of mouth opening. Trigeminal deafferentation, although it does not affect pecking or swallowing, severly impairs the efficiency of eating. Cinematographic analysis shows that the impairment is due to disruption of the neurosensory control of mandibulation-the process by which grain is grasped at the beak tip and moved to the back of the mouth.     

Separate factor analyses of the McCarthy Scales for groups of black and white children

Factor analyses of the McCarthy Scales of Children's Abilities (MSCA) were performed on separate groups of black (N = 124) and white (N = 688) children, aged 3.0 to 7.6 years, to assess the comparability of the underlying structures and to evaluate the construct validity of the MSCA for each racial group. Little Jiffy I (principal components) solutions produced four factors for the blacks and three for the whites. Each “white” factor had a coefficient of congruence of .85–.93 with one “black” factor, indicating the close similarity of the solutions. In addition, the factors which emerged for the blacks and whites corresponded to several of the scales constituting the MSCA, offering evidence of the instrument's construct validity for each racial group. The results of the study should enhance the use of the McCarthy Scales for assessing young children of all races.     

Recall of logical and pragmatic implications in sentences with dichotomous and continuous antonyms

Thirty-six subjects recalled sentences containing dichotomous or continuous antonyms in affirmative or negative form. The subjects made a considerable number of meaning-preserving recall errors for both dichotomous antonyms (not alive recalled asdead) and continuous antonyms (not hot recalled ascold). The negation of a dichotomous antonym logically implies its antonym, whereas the negation of a continuous antonym only pragmatically implies its antonym. Thus, the results suggest that subjects hearing sentences containing a logical or pragmatic implication tend to make the logical or pragmatic inference involved. Then, in recall, they do not remember that this was an inference and make the error of recalling the logical or pragmatic implication in place of the presented sentence.
