A review of outcome studies of rational-emotive therapy from 1982–1989

In 1977, DiGiuseppe and Miller provided a review of the literature assessing the effectiveness of Rational-Emotive Therapy (RET). In 1984, McGovern and Silverman completed a similar review for outcome studies conducted from 1977 through mid-1981. This present study is meant as a continuation of those reviews. The 89 studies reviewed are divided into three sections: outcome studies that do not compare Rational-Emotive Therapy with other types of treatment; a review of outcome studies that do compare RET with other types of psychotherapy; and a review of Rational-Emotive outcome studies that either combine RET with other therapies or are not appropriate for the first two sections. There does appear to be some increased sophistication in the research conducted since 1982. Increases were noted in the number of control groups used in the current research as well as in the number of follow-up studies. There also appears to be an improvement in the comparison of RET with other forms of therapy, and the number of problem areas in which RET has been tested has increased. A decrease in post-test only studies and an increased variety of subjects have also improved the current research. Issues such as socioeconomic status and I.Q. of subjects, duration of treatment, and lack of longitudinal studies remain unaddressed. It is suggested that future researchers concentrate on these specific problems to improve the credibility of RET. This review coincides with the previous findings that RET is a valuable, effective therapy that warrants increased research to broaden its application.Manuel S.

Illegitimacy, child abuse and neglect, and cognitive development

This study explored the relationship between illegitimate birth and cognitive development among 513 boys on probation. Prior research has shown that being part of a single-parent household leads to diminished verbal capacities and often puts a child in greater danger of abuse and neglect. Frequent abuse is thought to lead to the enhancement of visual and spatial skills relative to verbal skills through a process of "frozen watchfulness". I hypothesized that illegitimate boys from one-parent homes would have greater verbal-performance discrepancy scores than would boys from other combinations of birth status and family structure. These boys had the lowest verbal IQ and highest performance IQ scores and, hence, the largest discrepancy. These boys also suffered the highest degree of abuse and neglect of all four birth status/family structure combinations studied.     

A method for examining short-term retention of haptic cues in monkeys

Tasks used to examine short-term memory (STM) in animals have almost exclusively required retention of visual cues. To determine if haptic information can be retained, three rhesus monkeys were trained to perform, using only haptic cues, a simultaneous (SMS) and a delayed matching-to-sample (DMS) task. On each trial, the monkeys felt and responded to a sample stimulus on a centrally located manipulandum. They were then presented two comparison stimuli located on both sides of the central manipulandum. A response matching the comparison stimulus with the sample stimulus was reinforced. In SMS a mean of 2,725 trials was required to reach a criterion of 90% correct. As in DMS performance for visual cues, in haptic DMS the monkeys were capable of above-chance responding at retention intervals of greater than 1 min. This haptic DMS task should be useful for testing STM models, for examining the physiological basis of STM, and for examining drug effects.     

Effects of public and private deviancy on compliance with a request

A confederate requester asked subjects to write letters for an educational campaign after they had completed a battery of tests and received either deviant or nondeviant feedback. Half of the subjects were led to believe that the requester had knowledge of their test performance; the remaining half believed that the confederate did not know their test scores. Within these conditions, some subjects believed that complying with the request would involve future meetings with the requester while others were not led to anticipate any future interaction. As expected, deviants complied more than nondeviants replicating Freedman and Doob's (1968) results; however, neither the secret/known nor the future interaction variations produced effects. Contrary to the prediction that deviants are compliant because they wish to avoid mistreatment, secret deviants complied slightly more than known deviants. Compliance was discussed as instrumental in improving self-image.     

Formant transition duration and amplitude rise time as cues to the stop/glide distinction.

There is some disagreement in the literature about the relative contribution of formant transition duration and amplitude rise time in signalling the contrast between stops and glides. In this study, listeners identified sets of /ba/ and /wa/ stimuli in which transition duration and rise time varied orthogonally. Both variables affected labelling performance in the expected direction (i.e. the proportion of /b/ responses increased with shorter transition durations and shorter rise times). However, transition duration served as the primary cue to the stop/glide distinction, whereas rise time played a secondary, contrast-enhancing role. A qualitatively similar pattern of results was obtained when listeners made abrupt-onset/gradual-onset judgements of single sine-wave stimuli that modelled the rise times, frequency trajectories, and durations of the first formant in the /ba/-/wa/ stimuli. The similarities between the speech and non-speech conditions suggest that significant auditory commonalities underlie performance in the two cases.
