A discrete-trials/fixed-interval method of discrimination training

An efficient new method of discrimination training is described which has several advantages over older free-operant and discrete-trials procedures. Illustrative data on reversal learning in pigeons and goldfish are presented.     

Theory and method for research on aptitude processes

The theoretical and methodological concepts available to, and needed by, research on aptitudes as cognitive processes are discussed. Contemporary views of cognitive processes are examined in relation to individual difference constructs and methods used to examine their reliability and validity. Individual difference constructs are discussed in relation to cognitive process models and research thereon. Studies of short-term memory processes are reviewed to demonstrate the complementary strengths and weaknesses of experimental and correlational methods and concepts. A coordinated approach to the study of aptitude as information processing is suggested.     

A rapid method of toilet training the institutionalized retarded

Incontinence is a major unsolved problem in the institutional care of the profoundly retarded. A reinforcement and social analysis of incontinence was used to develop a procedure that would rapidly toilet train retardates and motivate them to remain continent during the day in their ward setting. Nine profoundly retarded adults were given intensive training (median of four days per patient), the distinctive features of which were artificially increasing the frequency of urinations, positive reinforcement of correct toileting but a delay for "accidents", use of new automatic apparatus for signalling elimination, shaping of independent toileting, cleanliness training, and staff reinforcement procedures. Incontinence was reduced immediately by about 90% and eventually decreased to near-zero. These results indicate the present procedure is an effective, rapid, enduring, and administratively feasible solution to the problem of incontinence of the institutionalized retarded.     

Dry pants: A rapid method of toilet training children

Toilet training sometimes requires considerable time. An intensive learning procedure was devised for shortening this training time and tested with 34 children who were experiencing toilet training problems. The procedure had the following major characteristics: (1) a distraction-free environment, (2) an increased frequency of urination by increased fluid intake, (3) continuous practice and reinforcement of the necessary dressing skills, (4) continuous practice and reinforcement in approaching the toilet, (5) detailed and continuing instruction for each act required in toileting, (6) gradual elimination of the need for reminders to toilet, (7) immediate detection of accidents, (8) a period of required practice in toilet-approach after accidents as well as (9) negative reinforcement for the accident, (10) immediate detection of correct toileting, (11) immediacy of reinforcement for correct toiletings, (12) a multiple reinforcement system including imagined social benefits as well as actual praise, hugging and sweets, (13) continuing reinforcement for having dry pants, (14) learning by imitation, (15) gradual reduction of the need for immediate reinforcement and (16) post-training attention to cleanliness. All 34 children were trained and in an average of 4 hr; children over 26 months old required an average of 2 hr of training. After training, accidents decreased to a near-zero level and remained near zero during 4 months of follow-up. The results suggest that virtually all healthy children who have reached 20 months of age can be toilet trained and within a few hours.     

Dimensional salience as a function of educational attainment and method of discrimination training

The effects of three methods of selective-attention training with 4-sided forms on the salience of an invagination physical dimension in discrimination judgments with a stimulus domain of 12-sided forms were examined for 6-year-old Ss of low and high educational attainment. The results demonstrated that training procedures involving perceptual demonstration or manipulation increase the invagination dimension salience in the 12-sided stimulus domain more than a verbal training procedure for low educational attainment Ss. Implications for the psychophysical study of relatedness of stimulus domains are discussed.     

The use of co-working (co-therapy) as a training method

This paper formed the basis of a Workshop at the A.F.T. Conference 1981, although the bulk of the theoretical material was not presented in the Workshop. The primary aim of the Workshop itself was to enable participants to think about how they themselves would use the co-working method as a way of training and to test these thoughts out to some extent in role-play.
The experimental part of the Workshop fell into two sections. In the first the aim was for participants to consider in pairs what they might wish to teach by this method and how; and in the second it was intended that they test out in pairs an attempt to teach a specific aspect of family therapy.
In practice members found in the first part some of the difficulties that this method presents, as shown in my research, and thus for the second part they felt it essential to focus on the issue of developing a contract between the two potential co-workers in order to clarify and confirm the nature of the training relationship. This was no doubt as it should be, since there is evidence that to press ahead with trying to teach a method in this close working relationship when there are substantial problems in, or uncertainty about the relationship can be disruptive. Hence the workshop as a whole was much concerned with the nature of the training experience rather than the actual transmission of family therapy skills.     

Independence training as a method of enhancing self-help skills acquisition of the mentally retarded

This study examined the effectiveness of independence training which involved using social reinforcement, information feedback, modeling and evaluation of self and others in teaching showering behavior to institutionalized mentally retarded adults. A treatment and a non-treatment group of 36 subjects each were used to assess training and maintenance of the target behavior. Analysis of results showed that treatment and no-treatment groups did not differ on baseline scores. However, residents in the treatment group performed significantly better than no-treatment subjects on post-test and three-month follow-up. Staff were of the opinion at post-test that treatment was perceived to be acceptable and nonpunitive.     

A general tableau method for propositional interval temporal logics: Theory and implementation

In this paper, we focus our attention on tableau methods for propositional interval temporal logics. These logics provide a natural framework for representing and reasoning about temporal properties in several areas of computer science. However, while various tableau methods have been developed for linear and branching time point-based temporal logics, not much work has been done on tableau methods for interval-based ones. We develop a general tableau method for Venema's CDT logic interpreted over partial orders (BCDT⁺ for short). It combines features of the classical tableau method for first-order logic with those of explicit tableau methods for modal logics with constraint label management, and it can be easily tailored to most propositional interval temporal logics proposed in the literature. We prove its soundness and completeness, and we show how it has been implemented.

Toward science‐informed supervision of clinical case formulation: A training model and supervision method

Case formulation is a core competency in the practice of clinical psychology and although many component skills can be taught in lectures, supervised clinical practice is a key step in moving from knowledge about case formulation to knowledge of formulation. The present paper outlines a model of science‐informed clinical practice and the ways in which clinical supervision may play a role. In addition, a methodology for assessing and benchmarking skills in case formulation is described to assist clinical psychology training programs to provide supervisees with normative feedback about their skills in case formulation. In so doing, the supervision of case formulation can become more informed by science and responsive to evaluation.     

3-D localization of virtual sound sources: Effects of visual environment, pointing method, and training

The ability to localize sound sources in three-dimensional space was tested in humans. In Experiment 1, naive subjects listened to noises filtered with subject-specific head-related transfer functions. The tested conditions included the pointing method (head or manual pointing) and the visual environment (VE; darkness or virtual VE). The localization performance was not significantly different between the pointing methods. The virtual VE significantly improved the horizontal precision and reduced the number of front-back confusions. These results show the benefit of using a virtual VE in sound localization tasks. In Experiment 2, subjects were provided with sound localization training. Over the course of training, the performance improved for all subjects, with the largest improvements occurring during the first 400 trials. The improvements beyond the first 400 trials were smaller. After the training, there was still no significant effect of pointing method, showing that the choice of either head- or manual-pointing method plays a minor role in sound localization performance. The results of Experiment 2 reinforce the importance of perceptual training for at least 400 trials in sound localization studies.
