Reversible operations in the balance scale task

The development of two types of reversible operations was examined in three tasks involving a two-armed balance scale. The first type of reversible operation, compensation between dimensions, was shown to undergo considerable development between eighth grade and college. Even eighth graders were inconsistent in applying compensation to those versions of the balance scale task that required it. Some subjects, primarily preschoolers, used the given information in a way that was the opposite of that required for correct answers, a result that has been reported for other tasks requiring compensation. A second type of reversible operation, termed “correspondence of patterns”, was also tested and it was tentatively concluded that the responses of the modal college student are not fully reversible in this sense. This finding is also similar to results obtained in judgments of time, speed, and distance and in social judgment studies with college students.     

Development of phonetic memory in disabled and normal readers

The development of phonetic codes in memory of 141 pairs of normal and disabled readers from 7.8 to 16.8 years of age was tested with a task adapted from L. S. Mark, D. Shankweiler, I. Y. Liberman, and C. A. Fowler (Memory & Cognition, 1977, 5, 623–629) that measured false-positive errors in recognition memory for foil words which rhymed with words in the memory list versus foil words that did not rhyme. Our younger subjects replicated Mark et al., showing a larger difference between rhyming and nonrhyming false-positive errors for the normal readers. The older disabled readers' phonetic effect was comparable to that of the younger normal readers, suggesting a developmental lag in their use of phonetic coding in memory. Surprisingly, the normal readers' phonetic effect declined with age in the recognition task, but they maintained a significant advantage across age in the auditory WISC-R digit span recall test, and a test of phonological nonword decoding. The normals' decline with age in rhyming confusion may be due to an increase in the precision of their phonetic codes.     

Social skills training and systematic desensitization in reducing dating anxiety.

Cooper et al. (1969) have criticized the types of target behavior chosen for therapy analogue studies for being irrelevant to clinical practice. A potential target behavior which appears to be pervasive, complex and directly relevant to clinical practice is interpersonal anxiety. Of special concern to college students is the interpersonal anxiety elicited by members of the opposite sex. especially in dating situations (Martinson and Zerface, 1970).An individual may experience interpersonal anxiety because of a deficit in social skills (reactive anxiety) or because of prior conditioning (conditioned anxiety) or because of some combination of both reactive and conditioned components. While it is possible that a treatment program aimed at a reduction of either of these anxiety components may be instrumental in ameliorating the other component, it would appear that a comprehensive treatment program would attempt to teach social skills as well as reduce conditioned anxiety.Desensitization procedures have demonstrated success in alleviating conditioned anxiety for a wide variety of clinical problems (Paul, 1969a. 1969b) and appears to be a logical choice for the conditioned component of dating anxiety. A number of outcome studies have reported some success in the use of in vivo desensitization (Rehm and Marston, 1968; Martinson and Zerface, 1970) and systematic desensitization (Stark, 1970) in reducing anxiety in date anxious subjects.The literature on treatment programs aimed at social skills training for date anxious subjects is meager. Melnick (1973) reported success in improving the appropriateness of the social behavior of subjects who had experienced a minimal dating history by the use of modeling, behavioral rehearsal and self-observation techniques.The present study was designed to test the relative effectiveness of two different types of treatment programs in alleviating interpersonal dating anxiety. The two experimental groups consisted of a systematic densensitization program which focused on the condition anxiety component and a social skills training program which focused on the reactive anxiety component.     

On the inconclusiveness of “crucial” cognitive tests of dissonance versus self-perception theories

Several recent experiments are claimed to have tested conflicting predictions of cognitive dissonance and self-perception theories. It is argued that these claims fail to take into account the capacity of each formulation to account adequately for results “predicted” by the other. This argument is then continued, at a metatheoretical level, to reach the conclusion that the two theories are not capable of producing unequivocally contradictory predictions of cognitive consequences of experimental procedures.     

Autocorrelation of choice-reaction times.

A choice-reaction (CR) task requires that the subject estimate, raking the warning signal or his response on the preceding trial as a reference point, the time when the reaction stimulus is due, so that he can begin deciding on his response at an appropriate time. This paper presents a model for the reproduction of temporal intervals, with particular emphasis on the sequential statistics of a series of such reproductions. When this model is concatenated with the sequential probability ratio test model for 2CRT, it provides a quantitative account of the pattern of autocorrelation found in a series of RTs. There is no corresponding autocorrelation in the incidence of errors, however, because after an error the subject systematically adjusts the epoch at which he begins sampling as a precaution against a further error. These post-error adjustments can readily be incorporated into the model. The ideas presented enable several different CR phenomena to be related, and they have implications for the relation between speed and accuracy, for the form of empirical distributions of RTs, and for the effects of temporal uncertainty.     

A critical comparison of two random-walk models for two-choice reaction time

Two random-walk models for two-choice reaction time, being the sequential probability ratio test model initially suggested by Stone and the relative judgment theory recently proposed by Link, are here compared. The comparison shows the precise mathematical relation between the models, the predictions they have in common, and two points at which they differ. Three experiments concerned with the effect of stimulus probability on two-choice reaction time are examined with respect to three predictions from the models. In this three-way comparison the two models are more like each other than either is to the data; a greater variety of phenomena is revealed than either model can at present accommodate.     

Behavioral treatment of obsessive-compulsive neurosis

Three chronic and severe obsessive-compulsive neurotics were treated with behavioral intervention strategies and psychotropic medication. The effects of treatment were evaluated in three separate experiments with single case experimental designs. The results suggest that response prevention was effective in reducing ritualistic behavior while the effects of flooding and antidepressant medication added little to outcome. The results also suggest that strategies aimed only at reducing compulsive behavior per se are insufficient in eliminating other associated difficulties (e.g., depressive symptoms, interpersonal problems) and that a comprehensive approach to treatment is needed.     

Required relaxation: a method of inhibiting agitative-disruptive behavior of retardates

Institutionalized retardates frequently exhibit agitative-disruptive behavior. Recent experiments have shown that overcorrective training in specific types of behavior can inhibit inappropriate behavior. A procedure was developed in which overcorrective practice in relaxation was given to each of eight adult retardates for their disruptions. The agitated resident was required to spend a fixed period of time in relaxation in his own bed upon each occurrence of agitation. This overcorrective relaxation resulted in a rapid, enduring and almost complete reduction in such behavior as self-injury, threats, physical aggression, screaming, crying, cursing and tantrums. Ward attendants strongly preferred the required relaxation procedure to the time-out technique and other inhibition procedures they had used. The procedure appears to be about as effective as alternative techniques and to have the advantages of ease of implementation and acceptability by ward staff and retardates as a ‘reasonable’ reaction to agitation.
