BEHAVIORAL ASSESSMENT FOR PEDIATRIC INTENSIVE CARE UNITS1

Two studies were conducted to analyze behaviors of staff and patients on a Pediatric Intensive Care Unit (PICU). In the first study, behavioral observation procedures were employed to assess patient state, physical position, affect, verbal behaviors, visual attention and activity engagement, and staff verbal behavior. On the average, one-third of the patients were judged to be conscious and alert but markedly nonengaged with their environment. In the second study, a member of the hospital staff provided alert patients with individual activities to determine whether a simple environmental manipulation could positively affect behavior of children in intensive care. Employing a reversal design, the activity intervention was found to increase attention and engagement and positive affect, and to decrease inappropriate behavior. Both studies demonstrate that behavioral assessment procedures can provide an empirical basis for designing PICU routines affecting children's psychosocial status, and, thus, complement current procedures designed to provide quality medical care.     

Learning family therapy: The dilemmas of an individual therapist

Individual therapists who begin doing family therapy often encounter some special difficulties directly related to their prior training and experience. Some therapeutic techniques of individual therapy, such as understanding and explaining the patient's problems on the basis of faulty parenting, must be relinquished and alternative means of alleviating guilt must be adopted. In doing family therapy individual therapists must adapt to the fact that they are less important than they are used to being and have less control over content and emotional tone of sessions. They must change their conceptions about the importance of privacy and secrecy. This article discusses some of the problems encountered when one is not thoroughly committed to a family therapy approach to treatment. Countertransference difficulties, problems stemming from wanting change, and the differing nature of the gratifications in the two therapeutic modalities are other topics discussed.     

FI SCHEDULES AND PERSISTENCE AT GAMBLING IN THE U.K. BETTING OFFICE

This study reports on the direct observations of customers in two U.K. betting offices gambling on horse and dog races. These observations revealed that bets were more frequently placed in the last minutes just prior to the start (the OFF), and that this was caused by high-frequency gamblers (customers who had eight or more bets in a session) consistently placing their bets in the last two minutes prior to the OFF. Low-frequency gamblers (three or fewer bets/session) avoided this time period placing their bets earlier, or after the OFF, i.e., on a later race. It was argued that the betting behavior of the “gamblers” could not be explained either in terms of “skillful betting” or solely in terms of variable ratio schedules but was more adequately accounted for in terms of an interval schedule. It was further suggested that time-based schedules might be of heuristic value in generally understanding persistence at gambling while losing.     

Direct Open Supervision: A Team Approach

Created in the absence of one-way mirror facilities, Direct Open Supervision combines elements of live supervision with team participation in training family therapists. The theory and application of this approach to direct supervision are described.     

Preservation of global order equivalence

Psychological data frequently can only be gives rank-order significance. This paper investigates and characterizes those cluster methods suitable for use in such a situation. The work is carried out in an abstract order theoretic setting but a relation is shown to earlier models due to Jardine and Sibson as well as Matula. It deals with that portion of the clustering process that starts with a dissimilarity measure defined on a set P and produces a nested sequence of reflexive symmetric relations on P.     

Focus of attention, chronic expectancy, and responses to a feared stimulus.

An attentional model of fear-based behavior is proposed and a study that tested the model is reported. It was predicted that among subjects with moderate fear of snakes, heightened self-attention during an approach attempt would cause increased awareness of existing anxiety, followed by one of two courses of events: Subjects who believed that they could do the behavior in spite of their fear were expected to redirect their attention to the behavior--goal comparison and exhibit no behavioral deficit. Subjects who doubted their ability to do the behavior were expected to divert their attention from the behavior--goal comparison and to withdraw behaviorally from the approach attempt. The results of the study support this reasoning. Discussion centers on relationships between the proposed model and previous theory.     

Temporal control of behavior and the power law

The performance of rats and pigeons under fixed-interval schedules was studied in two experiments. The duration of postreinforcement pause was a declining proportion of fixed-interval duration. For pigeons this was true both when the duration of the reinforcer was fixed and when it was increased in direct proportion to increases in fixed-interval duration; the longer reinforcer durations did, however, lengthen the postreinforcement pause at higher schedule values. A quantitative analysis of data from Experiments 1 and 2 and from other studies showed that fractional exponent power functions described the relationship between postreinforcement pause and fixed-interval value; similar functions have previously been observed in studies of temporal differentiation. It was concluded that power functions reflect a direct causal, rather than artifactual, relationship between performance and the temporal requirements of reinforcement schedules.     

Response preference within the Rotter I-E Scale: perceived locus of control of self, average, and ideal others

The Rotter I-E scale was administered to college juniors in education under five different instructional sets. Subjects were asked to complete it (a) as they would ordinarily (self-perception), (b) as they believed an average person of the same sex would, (c) as an average person of the opposite sex would, (d) as an ideal person of the same sex would, and (e) as an ideal person of the opposite sex would. As hypothesized, subjects saw the ideal person of both sexes as significantly more internal than themselves, while they saw the average person of both sexes as more external than themselves. These results suggest the general desirability of being perceived as internally oriented.
