Biofeedback and Control of Skin Cell Proliferation in Psoriasis (open access)

Biofeedback and Control of Skin Cell Proliferation in Psoriasis

The present study was designed to determine the effect of skin-temperature-biofeedback training on cellular proliferation in three psoriasis patients. It was hypothesized that (a) psoriasis patients would be able to consciously decrease skin temperature of psoriatic tissue, and (b) there would be a positive correlation between rate of cellular proliferation and temperature change. Results obtained indicated biofeedback training to be effective in decreasing the surface temperature of psoriatic tissue. A 2 X 7 analysis of variance for two repeated measures indicated the change in skin temperatures as a function of sample period to be significant, F (6,26) = 3.29, p < .02. Generalization of temperature-training effects from the biofeedback to the no-feedback condition were observed. Rate of proliferation decreased from pretraining to posttraining biopsies.

EMG Biofeedback Training: Effect on Behavior of Children with Activity-Level Problems (open access)

EMG Biofeedback Training: Effect on Behavior of Children with Activity-Level Problems

The relationships between muscle-tension level, motoric-activity level, and academic performance in the laboratory setting are investigated. Three participants were reinforced for reducing and increasing their tension levels, alternately, while engaged in a simulated academic task, and the effects of each on the rate of activity and academic performance were measured. Measures were also obtained on the rate of activity and occurrence of problem behavior in the subject's homes. Significant treatment differences were found which support a direct relationship between tension and activity level so that a decrease in EMG level was associated with a decrease in motoric activity, and an increase in EMG level was associated with an increase in motoric activity. The efficacy of using EMG biofeedback to train relaxation in children with activity-level problems to control their symptoms is supported, especially where such a technique can be used in a specific task-oriented situation.

Insomnia: Effects of Electromyographic Biofeedback, Relaxation Training, and Stimulus Control (open access)

Insomnia: Effects of Electromyographic Biofeedback, Relaxation Training, and Stimulus Control

Traditional treatment for insomnia has been chemotherapy-- despite short-term value and side effects. Need for an alternative has led to research on behavioral treatment methods for insomnia. Relaxation training has consistently produced effective results, but the limited research on biofeedback and stimulus control suggests that they too may be viable alternate treatment methods. The present research investigated electromyogram (EMG) biofeedback, pseudo-EMG biofeedback, relaxation, training, and stimulus control as methods of treating sleep-onset insomnia. Volunteers consisting of 12 males and 24 females were recruited through newspaper advertisements. Subjects had no known physical cause for insomnia and were either free of sleeping medication or kept their dosage constant during the study. Subjects were matched for age and sex, randomly assigned to one of the four treatment groups, then randomly assigned to one of three therapists. Results indicated that pretreatment EMG scores for the four groups were high but not significantly different-- while post treatment EMG scores were not significantly reduced. Pretreatment sleep-latency measures were high, but not significantly different from each other. Post treatment latency measures were significantly reduced, but not significantly different from each other. Correlation between EMG-change scores and sleep-latency-change measures was non-significant. Pretreatment nightly awakenings for the four groups …

Free Association as a Mnemonic Device for Retention in Younger/Older People (open access)

Free Association as a Mnemonic Device for Retention in Younger/Older People

The purpose of this study was to determine whether and to what extent free association following exposure to written material would affect the memory of that material, and whether the effect upon memory would vary with age of the subject. A test of learning (immediate retention) resulted in a significant difference in performance between young and old women--the older learning less. Free association was not found to be significant as a mnemonic aid to either age group, and was compared with characteristics of other more common mnemonics. Suggestions for additional research are discussed.

Anxiety-Relief Conditioning: An Empirical Investigation (open access)

Anxiety-Relief Conditioning: An Empirical Investigation

The current study investigated the efficacy of Wolpe's original (1954) paradigm of anxiety-relief conditioning. The procedure consisted of administering a mildly aversive electric shock to a subject for several seconds until the subject said the word "Relax," and the shock was terminated. Repeated pairings were claimed by Wolpe to condition physiological relief to the cue word, "Relax," which could then be employed in order to reduce anxiety in various anxiety provoking situations. Since there does not appear to be a generally accepted theoretical rationale to account for the reported efficacy of anxiety-relief conditioning, several theoretical rationales were discussed. In addition, a distinction was made between the anxiety-relief paradigm described by Wolpe (1954) and the aversion-relief paradigm employed by subsequent investigators (Gaupp, Stern, & Galbraith, 1972; Solyom, McClure, Heseltine, Ledwidge, & Solyom, 1972; Thorpe, Schmidt, Brown, & Castell, 1964). It was suggested that this distinction might be used to account for the failure of the current investigation to support the efficacy of anxiety-relief conditioning, as a review of the major study supporting its efficacy (Turnage & Wenrich, 1974) indicated that aversion-relief, rather than anxiety-relief, may have been employed. In the absence of strong supportive evidence for the efficacy of Wolpe's anxiety-relief …

Learned Helplessness, Attribution, and Clinical Depression (open access)

Learned Helplessness, Attribution, and Clinical Depression

To test predictions of learned helplessness theory and attribution theory, depressed and nondepressed subjects were exposed to a word-association task in a skill, chance, or no-instructional-set condition. Subjects were asked to make attributions of success and failure to four factors--ability, effort, task difficulty, and luck--and rate expectancy of success. The predictions of both theories were only partially confirmed. Difficulties relating to the experimental design may account for the failure of nondepressed/skill subjects to show greater expectancy change. As predicted, all subjects in the chance condition displayed similar expectancy changes. Also as predicted, nondepressed subjects did not rate effort as being the least influential factor. Depressed subjects, however, rated all factors equivalently, instead of rating effort least influential.

Imaginal Response Events in Systematic Desensitization (open access)

Imaginal Response Events in Systematic Desensitization

The present research was undertaken to investigate the effects of two independent variables considered potentially important to the reduction of fear through systematic desensitization. The first independent variable investigated was the importance of making covert motor responses when instructions were given to imagine motor behavior. Electromyographic measures were obtained on subjects' covert muscular activity as they imagined themselves raising their arms. The subjects were then classified, on the basis of their average electromyographic responsiveness, as high-responders (those showing relatively high levels when imaging movement) and low-responders. A 2 X 2 analysis of covariance showed a significant difference in the posttreatment scores of the high- and low responders on performance measures, the high-responders performing better. The difference between the two instruction groups was not statistically significant. Additional analyses indicate the importance of the instruction variable is mitigated by the extent to which subjects actually follow the particular instructions given. These data imply electromyography may be used in clinical practice as an assessment tool to determine which subjects are likely to respond to systematic desensitization. They also suggest the possibility of using response measures to train self-monitoring of imagery. Concerning the imagery construct, the present study offers an empirical alternative to the …

Cigarette Smoking Behavior: Self-Managed Change (open access)

Cigarette Smoking Behavior: Self-Managed Change

In the present study, three self-managed treatment programs were compared with respect to their ability to effect and maintain change in the cigarette smoking behavior of 27 subject volunteers from the population of employees of a Veterans Administration hospital. Subjects were randomly assigned to a self—imposed delay group, a self-directed relaxation group, and a self-monitoring group. The experimental program lasted 6 weeks with a 20-minute individual meeting each week. Three months following treatment, subjects were contacted by mail and were asked to monitor their smoking behavior for one week, and to return their average daily smoking rate by mail. The results provide support for the effectiveness of the self-management technique of self-imposed delay as a durability—enhancing treatment procedure. The effectiveness of self-management techniques as a general class of treatment strategies was not supported. A task for future research would be to establish the effectiveness of the delay technique implemented earlier in the cigarette smoking chain, as well as to determine whether effectiveness is increased or decreased by a specification of the content of a delay interval.
