The relationship between speed of information processing and cognitive ability

Speed of information processing as measured by various reaction time and inspection tasks has been shown to correlate with psychometric intelligence, and it has been suggested that general intelligence (g) is determined to some degree by the speed that information is processed. If this is so, then various measures of speed of information processing should correlate substantially with each other, and each should also correlate with a wide range of psychometric tests that load on g. Alternatively, intelligence may be considered to be a multi-faceted complex of partially related abilities with specific abilities being dependent upon specific cognitive processes. If this is the case, it should be possible to discover independent cognitive processes, some of which correlate with one facet or broad ability and some with another. This paper presents three experiments in which the relationship between intellectual ability and four speed of information processing measures was examined. These were rate of memory scanning, rate of retrieval of information from long term memory, speed of stimulus-response mapping and inspection time (IT). Results showed that correlations between IT and most reaction time measures of speed of information processing were low, and that correlations between different versions of IT were negligible. In addition, some cognitive tasks with verbal material (memory scanning rate for digits and Posner letter matching IT) correlated most substantially with Verbal Reasoning whereas non-verbal (two-line) IT consistently correlated with tests loading on g. It was thus suggested that while non-verbal IT may be a measure of a perceptual speed attribute that contributes to mental functioning, other “speed of information processing” parameters may be more specific to a subset of abilities.     

Rational cognitive therapy with public offenders

In addressing the issue of how offenders may help themselves face the world in prison and outside, this article outlines how the principles of rational emotive therapy as outlined by Ellis and Maultsby can be simplified for use with this population in order to provide them a method for understanding and alleviating unhelpful emotional reactions. An example is provided to illustrate how a rational self-analysis model can be taught as written homework in individual or group sessions. Using the RSA model, offenders are taught to review and better understand the meanings of irrational words and how they upset themselves. Overall, our experience has been that offenders of many persuasions can be taught to be more rational and logical—an essential foundation for successful rehabilitation.

Blending qualitative and behavior analytic research methods to evaluate outcomes in inclusive schools

Following Haring's (1992) recommendation, we have utilized qualitative research techniques to assist us in designing a program of research on inclusive education which is responsive to the outcome values and priorities identified by teachers and parents. Using interviews, observations, and document analysis to follow 35 children in full inclusion classrooms over a period of two years, we have described outcomes for these children in three major domains. These outcome domains, and subthemes within them, have been evaluated and revised based on interviews and social validation ratings by parents and teachers. Dependent measures based on our qualitative research findings are currently being used in a series of behavior analytic studies designed to evaluate the effects of specific interventions on outcomes of inclusion for children with and without disabilities.     

Retention and treatment failure in Classwide Peer Tutoring: Implications for further research

Knowledge of basic arithmetic facts aids in the acquisition and speed of performance of arithmetic operations. A peer mediated instructional procedure, Classwide Peer Tutoring (CWPT), has been shown to increase the rates and accuracy of students responses to academic tasks and to improve student performance on a variety of academic tasks. The present investigation evaluated the retention of 100 subtraction items by primary grade-age children with mild disabilities using CWPT for 10 weeks. Short- and long-term retention of items, and rate of correct responding were assessed. Results indicated that the students' average pretest score was 58.0% correct, and their average weekly posttest score was 87.12 correct, a 27% improvement in accuracy. Short- and longer-term retention measured on posttests was 88.7 % and 85.0% correct, respectively. Improvement in students rate of accurate responding to subtraction items practiced during CWPT was obtained. Student failure to learn particular items was not attributable to fewer opportunities to practice these items, less accurate practice, or item difficulty. Students reported positive evaluation of CWPT and perceived positive social and self esteem outcomes. Directions for future research focusing on retention and analysis of treatment failure are suggested.     

Discrimination of picture requests for missing items among young children with developmental disabilities

Two experiments were conducted to assess discrimination of picture requests for missing items among young children with developmental disabilities. In Experiment 1, three children were first taught to request one object when it was missing from a set of two related leisure items. In Experiment 2, two children were taught to request one object belonging to a set of three leisure items. In both studies the requesting response consisted of pointing to a photograph of the missing item. After acquisition of the initial request, discrimination of picture requests was assessed when the second item (Experiment 1) and second or third item (Experiment 2) was missing. Requests for the untrained items emerged in the presence of natural maintaining contingencies and in the absence of instructional prompts for all but the third child in Experiment 1. This child required continued intervention on the initial request. The results suggest that for some children a sequence of intervention and the programming of natural maintaining contingencies may prove effective in promoting the discrimination of picture requests for missing items among young children with developmental disabilities.     

Suicidal behavior among youth with severe emotional disturbance

The purpose of this study was to replicate an investigation of risk behaviors associated with suicidal behavior in public high school students, in a population of high school age youth with severe emotional disturbance (SED). Subjects for the study were clients of the South Carolina Continuum of Care (COC) (N=83). Information on suicidal thoughts and acts, aggressive behaviors, substance use and physical recklessness was gathered using a modified version of the self-report National Youth Risk Behavior Survey. Four percent of the youth reported seriously considering suicide, 8% reported planning how they would attempt suicide, 10% reported actually attempting suicide at least once, and 6% reported attempts requiring medical treatment Of the 13 youth who reported attempting suicide, four (31%) did not report planning an attempt. All suicidal behaviors except thoughts occurred more in girls than boys with SED. Alcohol and illicit drug use were associated with suicidal behavior, with larger odds ratios for attempts than for thoughts/plans. Youth with SED who use alcohol and illicit substances are particularly at risk of suicidal behavior. A high index of suspicion is appropriate when evaluating suicidal risk in girls with SED, especially in the presence of known alcohol or substance use.Continuum of Care for Emotionally Disturbed Children Division, S.

Four dialogue systems

The paper describes four dialogue systems, developed in the tradition of Charles Hamblin. The first system provides an answer for Achilles in Lewis Carroll's parable, the second an analysis of the fallacy of begging the question, the third a non-psychologistic account of conversational implicature, and the fourth an analysis of equivocation and of objections to it. Each avoids combinatorial explosions, and is intended for real-time operation.     

Extraversion and happiness

The relationship between extraversion and happiness or subjective well-being (SWB) is one of the most consistently replicated and robust findings in the SWB literature. The present study was conducted in order to examine three key aspects of the relationship: (1) Whether it is primarily substantive in nature, or a product of self-report response artifacts, such as social desirability; (2) What the underlying systems or mechanisms involved in the relationship are; and (3) Whether Eysenck's two dimensions of extraversion and neuroticism combine additively or interactively in their influence upon an individual's level of SWB. The results are supportive of the substantive nature of the relationship, and suggest that both situational and personality factors combine to produce the positive correlation between extraversion and SWB. In terms of the interaction of extraversion and neuroticism, the results are mixed in supporting both an additive and interactive relationship.     

Research note: Peak velocity timing invariance

Summary Subjects used arm movements to move a dot on a visual display into a predefined target area. Measures of the peak velocity values and the timing of the peaks were taken for the initial (preplanned) and the immediately subsequent (corrective) phases of movement. In both phases the value of the maximum velocity depended on task parameters such as amplitude. However, the time of the peak of each phase relative to its onset was invariant. Some implications of these observations for the nature of motor programs are discussed.     

The narcissistic personality in group psychotherapy

The author presents an interesting version of the Narcissus myth which she combines with the legend of Peter Pan for a better understanding of the narcissistic personality in group therapy. A lively case is presented of a young man named Jeffrey, whose narcissistic defenses were dismantled during a three-year group participation. A particular encounter between Jeffrey and another client and a powerful intervention by the therapist is described. The therapeutic importance of the group therapist as a firm but protective parent for these clients is emphasized. Definitions of narcissistic are given and some generalizations about these personalities in group therapy are explored.She has completed a book entitledChange in the Context of Group Therapy to be published by Brunner/Mazel in 1984.
