On-line Apple II for the recording and analysis of complex motor movements

The system described here was prompted by the need for a method of separately recording various components of a complex motor act. The task involved vertical, horizontal, and turn components. Our particular interest was the relation between integration of components and level of skill demonstrated. The peripheral equipment provides a separate analogue output for each component and plugs directly into the Apple’s game-paddle input. Trial data are stored directly on disk and can be retrieved for subsequent graphical plotting and analysis. The Apple II accommodates up to four inputs and returns results for movements as fast as .05 sec. The programming system can be used, without modification, for a wide variety of motor tasks. No additional interface or clock is required.     

Some simple Apple II software for the collection and analysis of observational data

Two general-purpose software packages for collecting and analyzing observational data from a variety of settings are discussed. One package is designed for coding mutually exclusive behavioral states using the Apple’s keyboard as an input device. The other is designed to monitor temporally overlapping behaviors, and it makes use of the Apple II’s built-in game-control button inputs to indicate up to three behavioral states that may occur simultaneously.     

The analysis of multiphasic signals with the Apple II/FIRST microprocessor system

An Apple II/FIRST system has been developed to control classical conditioning experiments, collect analog data, and extract dependent variable measures of conditioning from uniphasic response signals (Scandrett & Gormezano, 1980). The present paper covers an expansion in the capabilities of the system by the development of a multiphasic signal analysis algorithm written in FIRST, an interactive, high-level, dictionary-based language. The program provides unprecedented efficiency, sensitivity, and flexibility in the analysis of multiphasic analog response signals in classical conditioning experiments. Moreover, the program has the potential to analyze even more complex signal patterns.     

Response-restriction analysis: II. Alteration of activity preferences

We used response-restriction (RR) assessments to identify the preferences of 7 individuals with mental retardation for a variety of vocational and leisure activities. We subsequently increased their engagement in nonpreferred activities using several procedures: response restriction per se versus a Premack-type contingency (Study 1), supplemental reinforcement for engagement in target activities (Study 2), and noncontingent pairing of reinforcers with nonpreferred activities (Study 3). Results indicated that preferences are not immutable and can be altered through a variety of relatively benign interventions and that the results of RR assessments may be helpful in determining which types of procedures may be most effective on an individual basis.     

Participation by women in behavior analysis. II: 1992

Participation by women and men in (a) the editorial process and publication of three behavior analysis journals, (b) leadership in the Association for Behavior Analysis (ABA) and the Society for the Experimental Analysis of Behavior, and (c) participation in the 1982 and 1991 conventions of the Association for Behavior Analysis are described. The data indicate that the relative involvement of women in all three areas is lower than the percentage of ABA members who are women (31%) and is considerably lower than the percentage of women in society at large (51%). This underrepresentation of women in editorial and leadership roles in behavior analysis mirrors the reported phenomenon of a glass ceiling for women in leadership roles in business and industry. The men who control our institutions are asked to share power and responsibility by increasing the involvement of women in behavior analysis.     

Ruler vs. the Apple II/FIRST system analysis of analog signals in classical conditioning

In our judgment, the Apple II/FIRST system (Scandrett & Gormezano, 1980) is an efficient and versatile system for experimental control and data acquisition in classical conditioning experiments. However, these attributes would be of limited value if the system did not extract measures from our analog signals with a high degree of correspondence with our ruler measurement procedures. Accordingly, we determined the system’s validity in extracting measures of CR occurrence and CR latency in three conditioning experiments. Pearson productmoment correlation coefficients indicated a very satisfactory degree of agreement on measurements made by the Apple II/FIRST system and ruler. Moreover, intraclass correlations and analysis of variance procedures applied to percent CRs and CR latency revealed several small, but divergent, differences between ruler and computer measurement of CR latency across the three experiments. However, subsequent analyses of variance revealed that the number and pattern of significant sources of variation for ruler or computer measurements were virtually identical. Accordingly, we have concluded that our system can successfully replace our traditional method of ruler measurement.     

Refining the experimental analysis of academic skills deficits: part II. Use of brief experimental analysis to evaluate reading fluency treatments

The technology of brief experimental analysis is just beginning to be used for identification of effective treatments for individual students who experience difficulty with oral reading fluency. In this study, the effect of a reading fluency treatment package was examined on easy and hard passages, and generalization was assessed on passages with high content overlap. The results suggest that the treatment package increased reading fluency for all 3 students. Effects were moderated by difficulty level for all 3 students. Results are discussed in terms of future refinements to the procedures, validation of the methods, and potential applications in clinical and school settings.     

On transferred permissive or approving superego functions: the analysis of the ego's superego activities, Part II

The author explores another major anxiety-relieving resistance, namely, the re-externalized and transferred fantasy of authority figures offering affectionate approval, with implicit permission for openness and disclosure. The conditions the patient experiences as safe for exposure of conflictual material are based on fantasy, not on a realistic sense of permission from analysis of resistance. Wider-scope therapeutic attention appears to create natural obstacles to an interest in the analysis of the ego's superego activities from which less vulnerable patients could benefit. The author presents clinical examples of the analysis of this second type of transference of defense and discusses the implications for unifying diverse theories.     

Childhood depression and conduct disorder: II. An analysis of family interaction patterns in the home.

Few researchers have assessed family interaction patterns associated with childhood depression, especially using observations in natural settings. We directly sampled the interaction patterns of families with depressed, conduct-disordered, mixed depressed-conduct-disordered, and comparison children ages 7-14 years in their homes during the evening meal. Observational measures were taken of positive and aversive behaviors and affect expression for both parents, the referred children, and their siblings. Results replicated previous research showing that conduct-disordered children express high levels of aversive behavior and anger and are part of a family system marked by conflict and aggression. The depressed children were exposed to maternal aversiveness but did not show any evidence of elevated levels of anger or aversiveness in their own behavior. Surprisingly, this was also true for the mixed-disorder children. High levels of depression in both groups of depressed children were associated with low levels of conflict and anger in family members. Overall, siblings showed very similar patterns of behavior, and were exposed to similar patterns of parental behavior, as the referred children. Results are discussed in terms of family models that emphasize the function of aggression and depression in the maintenance of child psychopathology.     

Enriching the Fieldwork II Experience

The shortage of occupational therapists working in mental health is of serious concern to the profession. This article will briefly describe the current issues related to manpower, recruitment and level II fieldwork education. It will then discuss the development, utilization and impact of one educational program designed to increase student interest in mental health by supplementation of the level II fieldwork experience. In conclusion, this paper will give suggestions for future strategies that may lead to both improved level II education and increased student interest in mental health as a career choice.     

Countering perfectionism in research on clinical practice II: Retrospective analysis of treatment progress

A simple correlational study is described which has methodological advantages, when compared with an equivalent manipulative (i.e., quasiexperimental) research design, for examining exploratory questions about treatment outcome. These advantages stem from the fact that retrospective designs, when compared with prospective ones, are much less likely to involve ethical problems due to offering relatively ineffective or unnecessary treatment, and less likely to involve confounds from newly hypothesized differential expectations about treatment. Based on Millon Clinical Multiaxial Inventory (MCMI) scale scores, clients with high levels of histrionic or narcissistic (and possibly also those with antisocial, compulsive and paranoid) personality traits seemed to profit more from RET than those without such traits. Clients with high levels of schizoid, avoidant, and schizotypal traits (and probably also clients with strong passive-aggressive traits, and possibly also clients with strong dependent and borderline traits) seemed to profit less from RET than those without such marked traits. We have previously shown that the relatively healthy personality traits and disorders are associated with global self-upping and the relatively sick ones with global self-downing, as well as contrasting patterns of positive and negative reactions to stressful events. Our findings here support the concept that clients who consistently handle life situations well will tend to progress most rapidly in therapy, and those who generally handle life situations badly will tend to progress slowly. Personality traits may be especially significant markers for therapeutic attention to problems stemming from global self-rating. Expectations based on the severity of global self-upping and/or self-downing may be good predictors of therapeutic progress. In contrast, expectations about RET outcomes based on severity of distress or neediness will probably be less accurate.Dr. Russell C. Leaf is Associate Professor of Psychology at Rutgers.

Idea and reality of training analysis. A plea for reforms (II)

Thom? pleads for a form of psychoanalytic training in which the critical appropriation of psychoanalytic and humanistic knowledge as well as therapeutic competence are the focus and in which the personal analysis (super-therapy) is no longer overvalued. It seems possible to limit the length of training analyses. Qualification for professional practice should be worked out exclusively within the training institute and in close collaboration with instructors.     

The analysis of proximities: Multidimensional scaling with an unknown distance function. II

The first in the present series of two papers described a computer program for multidimensional scaling on the basis of essentially nonmetric data. This second paper reports the results of two kinds of test applications of that program. The first application is to artificial data generated by monotonically transforming the interpoint distances in a known spatial configuration. The purpose is to show that the recovery of the original metric configuration does not depend upon the particular transformation used. The second application is to measures of interstimulus similarity and confusability obtained from some actual psychological experiments.     

Behavioral economics of drug self-administration. II. A unit-price analysis of cigarette smoking.

In behavioral economics, the ratio of response requirement to reinforcer magnitude is referred to as unit price. Previous research with nonhuman subjects has demonstrated that (a) comparable amounts of food are consumed at the same unit price even though different response requirements and reinforcer magnitudes comprise that unit price and (b) increases in unit price decrease food consumption in a positively decelerating fashion. The present study assessed the generality of these findings to the cigarette smoking of 5 human volunteers. During approximately 18 3-hr sessions, various combinations of response requirement (fixed-ratio 200, 400, and 1,600) and reinforcer magnitude (1, 2, and 4 puffs per bout) were arranged. Consumption (i.e., the number of puffs) generally was comparable at the same unit price independent of the response requirement and reinforcer magnitude comprising that unit price. In addition, increasing unit price generally decreased consumption in a positively decelerating fashion. These results extend the generality of the unit-price analysis to human cigarette smoking. Moreover, these results further support the position that reinforcer magnitude and response requirement are functionally equivalent and interact to determine consumption. The concept of unit price, by integrating and summarizing the effects of those two operations, provides a more parsimonious explanation of the results than do separate evaluations of the effects of response requirement and reinforcer magnitude.
