The role of physiological attention-focusing in the relaxation treatment of sleep disturbance,general tension,and specific stress reaction

Three experiments comparing the effects of muscle tension-release relaxation with vs without physiological attention-focusing and no-treatment on (a) sleep disturbance, (b) general tension, and (c) a variety of time estimation, heart rate perception, and stress reaction measures, are reported. The two relaxation conditions produced equivalent reductions in latency to sleep onset reports, suggesting the importance of tension-release in the relaxation treatment of sleep disturbance. Relaxation without physiological attention-focusing was unexpectedly superior to the other relaxation condition in reducing reported daily tension, supporting Denny's (1976) hypothesis that pervasive anxiety may be a function of anxiety conditioned to relaxation-produced cues. Sleep disturbed subjects over-estimated elapsed time, and relaxation training improved accuracy of time estimation. Several additional differences between sleep and tension subjects and among the three treatment conditions on physiological activity during stress are reported and discussed.     

Counsellors as teachers

An examination of the arguments for and against the role combination of teaching and counselling leads to a view of counselling as being, in some senses, an ingression into the traditional practices of teaching and, in other senses, an egression from them. The traditional practices of teaching are, therefore, analysed in such a way as to generate items for an inventory to measure 'teacher identification'. The inventory also includes items which invite respondents to reject the ingression of non-teaching principles and practices. En route to the development of the inventory, some observations are made concerning the kinds of role combination with teaching which counsellors tend most to resist.     

Algebraic models for integration of painful and nonpainful electric shocks

Subjects rated the average intensity of two sequentially presented electric shocks, which were either painful (intensity range from 1 to 4 mA, Experiment 1) or nonpainful (intensity range from .6 to .9 mA). In both experiments, stimuli were presented in a 4 by 4 factorial design to allow tests of algebraic models of the integration process under analysis of variance (Anderson, 1970, 1974). Both sets of data were fit by the equation R_{i j}=w₁s₁+w₂+s₂, (w₁+w₂=1), where R_{i j}is the rating scale response, s₁ and s₂ the scale values for the first and second stimuli, respectively, and w₁ and w₂ associated weights. When stimuli were painful, w₁=w₂, and when stimuli were nonpainful, w₁< w₂. Subjective scale values as a function of stimulus intensity appear to increase nonlinearly for painful stimuli and linearly for nonpainful stimuli. Some implications of the results for pain research are discussed.     

Simultaneous vs sequential discriminations of Markov-generated stimuli

This experiment required Ss to make same-different classifications of Markov-generated histoforms that were distortions of three different prototypes. Task memory requirements were varied by presenting stimuli either simultaneously or sequentially for comparison, and the effects of shifts in memory requirements were also assessed. Classification performance in all cases was found to be superior under the simultaneous condition. Postshift performance was strictly a function of the mode of stimulus presentation following the shift, rather than the memory requirements present in the initial trials. These results, coupled with the observed relationships between performance and a measure of individual stimulus variability under the two memory conditions, strongly suggest that prototype encoding has limited relevance to performance in the same-different classification task used here.     

Discussion: Reflections from the clinical trenches

This paper involves a series of personal reflections on the deleterious impact of excessive bureaucracy and other institutional forces on the psychosocial treatment of the chronically mentally ill. The writer appeals to three groups of mental-health practitioners—behavior analysts, practicing clinicians, and academic clinicians—to promote cultural change by advocating a restructuring of large-scale bureaucracies with the concurrent establishment of multiple community-based associations.     

Evaluation of unconstrained sorting data

Two statistics are offered for evaluating unconstrained sorting performance in a specific task when categories are E-defined. One statistic is based upon empirically estimated sampling distributions and can be used for determining sorting performance significantly deviant from chance for any number of S-defined categories; the second statistic can be used to evaluate consistencies between S- and E-defined categories, regardless of the number of categories used by S. The present procedure provides a statistical basis for evaluation of performance where no adequate evaluation procedures are now available.     

Empowering people with physical disabilities through advocacy skills training

Members of an advocacy organization for people with physical disabilities were trained to identify and report issues at group meetings. In addition, two consecutive chairpersons were trained to conduct action-oriented meetings. Measures of group members' activities outside meetings and related outcomes on identified issues were also collected. Results indicated increases in the number of disability-related issues reported by trained members and consistent improvements in chairperson performance following training. Retrospective interviews and permanent records showed that advocacy activities, as well as the outcomes of members' actions, increased after training. These findings and their implications for the empowerment of people with disabilities are discussed.     

Evaluation of a shaping procedure with the changing-criterion design

This study used the changing-criterion design to document the effectiveness of a behavioral training package to alter the topography of a complex behavior. In this case, bed-making was established for a severely debilitated adult mental patient who was chronically institutionalized. Experimental control was demonstrated by a step-wise progression in performance to the final target behavior. The changing-criterion design provides an effective record of the shaping process and is sufficiently flexible for other single-subject design elements to be included.     

The importance of conduct problems and depressive symptoms in predicting adolescent substance use

The current study assessed the relative importance of conduct problems and depressive symptoms, measured at two ages (11 and 15), for predicting substance use at age 15 in an unselected birth cohort of New Zealand adolescents. Among males, when the relative predictive utility of both conduct problems and depressive symptoms was assessed, only pre-adolescent depressive symptoms were found to predict multiple drug use 4 years later. No predictive relation was found between early symptomatology and later substance use among females. The strongest association between predictors and substance use emerged between age 15 multiple drug use and concurrent conduct problems for both males and females. Finally, both conduct problems and depressive symptoms at age 15 were also found to be associated with concurrent self-medication among females.This work was supported by USPHS grants MH-43746 and MH-45070 from the Antisocial and Violent Behavior Branch of the National Institute of Mental Health to Terrie Moffitt.
