Effect of playing a video game on a measure of spatial visualization

70 undergraduate students, without any prior experience of video games playing, were given a pretest and a posttest on the Space Relations Test of the DAT, Forms A and B being, respectively, administered on the two occasions. The experimental group of 38 had eight sessions of playing the Zaxxon video game, each session including five plays. The control group of 32 received no such treatment. A 2 (sex) by 2 (group) analysis of covariance, using pretest scores as the covariate, yielded a significant effect for group which supports the hypothesis that spatial visualization test scores can be improved by video game playing. Moreover, the sex-related difference in visual-spatial skills frequently reported does not appear on the pretest. Finally, no effect for sex and no interaction of group X sex were found, indicating that both male and female subjects gained equally from playing Zaxxon.     

Sleep deprivation and naps

It is important for military commanders to know the likely effects of a small amount of sleep under conditions of sustained operations. To this end, two laboratory-based experiments on naps were carried out. The first examined the effect of 2 h of sleep following 90 h of wakefulness. Ten infantrymen subjects were not told the scheduled length of their vigil, or that they would be allowed a nap at some stage, until a few hours before the 2-h nap. After 3 nights without sleep, the subjects’ average cognitive performance was 55% of the control values. During a test session immediately before the 2-h nap, performance improved by 30%, to 85% of control values, indicating the considerable effect that the incentive of knowing that a nap is imminent can have on even severely sleep-deprived subjects. In the second experiment, two groups, each of six infantrymen, took part in a 5-day trial; for one group, 4 h of uninterrupted sleep was scheduled and for the other, four l-h naps in each 24-h period. There were no significant differences in cognitive test scores or mood between the two groups. On the last experimental day, cognitive test and mood scores were not significantly different from baseline values for either group, indicating the utility of 4 h of sleep, either in one uninterrupted block or in four scheduled 1-h naps per 24 h.

Independence training vs modeling procedures for teaching phone conversation skills to the mentally retarded

Forty-five mildly mentally retarded adults were assessed for deficits in telephone conversational skills. They were ranked on the basis of their pretest scores and matched into triplets on skill level. One member from each of these groups was then randomly assigned to either a no-treatment control group, a modeling condition or independence training—a treatment that incorporated social reinforcement, instructions, performance feedback, modeling, shaping by successive approximations and self-monitoring and evaluation. For the two latter conditions, treatment was provided three times weekly for 2 months in group sessions (N = 5) of 1 hr duration. The dependent variable, conversational skills of subjects was assessed at pretest, posttest and at a 3-month follow-up based on verbal responses that subjects made to nine questions asked by an experimenter and related social responses during a phone call. Independence training proved to be significantly more effective than the other two experimental conditions at posttest and follow-up. In addition, modeling proved to be significantly more effective than the no-treatment controls at both of these assessment points.     

Effect of manipulating positive and negative feedback on goal orientations, perceived motivational climate, satisfaction, task choice, perception of ability, and attitude toward physical education lessons

This study examined the effect of different types of feedback on goal orientation, perception of motivational climate, satisfaction, and boredom in physical education (PE) classes, pupils' preferences for challenging versus easy tasks, pupils' attitudes towards PE lessons, and perception of gymnastic ability. 95 subjects in three treatment conditions (positive feedback, negative feedback, and both feedback types) participated in 14 lessons and completed pre- and postintervention measures. Results showed that subjects in the positive feedback group had significantly higher scores on learning-oriented motivational climate and enjoyment than the subjects of the negative feedback group. The negative feedback group reported higher scores on performance-oriented motivational climate than the positive feedback group. Results also showed that subjects in the group receiving both types of feedback had lower scores on learning-oriented motivational climate, higher scores on enjoyment than the negative feedback group, and lower scores on boredom than the positive feedback group. The effects of feedback on physical education students' motivation are discussed.     

Programming generalization and maintenance of treatment effects across time and across settings

Effects of three experimental and one control strategy were investigated in facilitating generalization and maintenance of treatment effects after two months in a token-economy classroom. At the conclusion of treatment, subjects were randomly assigned to one of three maintenance strategies or a control group and returned to their regular classrooms. The maintenance strategies were peer reprogramming, equating stimulus conditions between the experimental and regular classrooms, and teacher training in behavior management techniques. The maintenance strategies were implemented in the regular classroom for a two-month period and then terminated. Results indicated a powerful treatment effect produced by the token economy. Behavior maintenance effects following treatment were also obtained. The mean per cent appropriate behavior for the peer reprogramming and equating stimulus conditions strategies was significantly greater than the mean for the control subjects. The teacher training and control group means were not significantly different.     

Task-related and person-related variables influence the effect of low back pain on anticipatory postural adjustments

BackgroundPeople with low back pain exhibit altered postural coordination that has been suggested as a target for treatment, but heterogeneous presentation has rendered it difficult to identify appropriate candidates and protocols for such treatments. This study evaluated the associations of task-related and person-related factors with the effect of low back pain on anticipatory postural adjustments.MethodsThirteen subjects with and 13 without low back pain performed seated, rapid arm flexion in self-initiated and cued conditions. Mixed-model ANOVA were used to evaluate group and condition effects on APA onset latencies of trunk muscles, arm-raise velocity, and pre-movement cortical potentials. These measures were evaluated for correlation with pain ratings, Fear Avoidance Beliefs Questionnaire scores, and Modified Oswestry Questionnaire scores.FindingsDelayed postural adjustments of subjects with low back pain were greater in the cued condition than in the self-initiated condition. The group with low back pain exhibited larger-amplitude cortical potentials than the group without pain, but also significantly slower arm-raise velocities. With arm-raise velocity as a covariate, the effect of low back pain remained significant for the latencies of postural adjustments but not for cortical potentials. Latencies of the postural adjustments significantly correlated with Oswestry and Fear Avoidance Beliefs scores.InterpretationDelayed postural adjustments with low back pain appear to be influenced by cueing of movement, pain-related disability and fear of activity. These results highlight the importance of subject characteristics, task condition, and task performance when comparing across studies or when developing treatment of people with low back pain.     

Individualized Behavior Therapy for Alcoholics – Republished Article

A behavior therapy for alcoholism was designed based on the rationale that alcoholic drinking is a discriminated, operant response. Treatment emphasized determining setting events for each subject’s drinking and training equally effective alternative responses to those situations. Seventy male, hospitalized, Gamma alcoholics were assigned to a treatment goal of either nondrinking (N = 30) or controlled drinking (N = 40). Subjects of each group were then randomly assigned to either an experimental group receiving 17 behavioral treatment sessions or a control group receiving only conventional treatment. Treatment of experimental groups differed only in drinking behaviors allowed during sessions and electric shock avoidance schedules. Nondrinker experimental subjects shaped to abstinence, while controlled drinker experimental subjects practiced appropriate drinking behaviors with little shaping, a result attributed to instructions. Follow-up measuring drinking and other behaviors found that experimental subjects functioned significantly better after discharge than control subjects, regardless of treatment goal. Successful experimental subjects could apply treatment principles to setting events not considered during treatment, suggesting the occurrence of rule learning. Results are discussed as evidence that some “alcoholics” can acquire and maintain controlled drinking behaviors. Traditional treatment of alcoholics may be handicapped by unvalidated beliefs concerning the nature of the disorder.     

Effects of short-term counseling on Career Maturity of tenth-grade students

The effectiveness of short-term counseling on Career Maturity of tenth-grade students as measured by the Career Maturity Inventory was studied. The Career Maturity Attitude Scale and the Self Appraisal subscale of the Competence Test were administered to a random sample (87 subjects) of tenth-grade students. The subjects whose scores fell below the mean were assigned randomly to experimental and control groups. The experimental group (17 subjects) received special counseling during a short term of 6 wk. Using repeated measures of analysis of variance, a statistically significant interaction was found with both the Self Appraisal subscale scores and the Total scale scores. Results indicate that career maturity as a developmental process can be measured and facilitated through counseling.     

Psychometric detection of schizotypy: perceptual aberration and physical anhedonia in relatives of schizophrenics.

We administered scales of Perceptual Aberration (PERAB) and Physical Anhedonia (PHYSAN), traits that may be related to risk for schizophrenia, to 54 schizophrenics, 146 of their first-degree relatives (evaluated for schizophrenia-related disorders), and 178 normal subjects (screened for psychotic disorders in them or their relatives). For both scales, there was a significant effect of group membership. For the PERAB scale, the schizophrenics had higher scores than the normal subjects, who had higher scores than the relatives. For the PHYSAN scale, schizophrenics had higher scores than their relatives, who had higher scores than the normal subjects. Patterns of familial correlations also suggested that physical anhedonia, but not perceptual aberration, may be familial among schizophrenics and their relatives. The PHYSAN scale, but not the PERAB one, may be a useful indicator of liability for schizophrenia among the relatives of affected probands.     

Symptoms,blood-pressure information and mood effects on symptom recall

Abstract

After completion of an illness symptom checklist (PILL) covering the previous three months, 97 nor-motensives were allocated to either experimental (false pressor feedback, n=42), or information control (accurate pressor feedback, n = 55), groups. The median reported symptom score divided high from low symptom subjects. All were given standard cuff blood pressure (BP) assessment and were normotensive. However, experimental subjects were misinformed that their BP was raised while information control subjects were told their BP was normal. Subsequently, subjects completed the state anxiety form of the State-Trait Personality Inventory, the PILL, and were asked about their belief of the ascribed BP label (normo/hypertensive) and then any perceived causal relationship between their BP and symptoms. Experimental subjects had significantly higher anxiety scores but no change in symptom recall after pressor feedback, whereas control subjects showed lower anxiety scores and decreases in symptom recall.

A post hoc treatment control (no pressor information) group (n = 20) excluded effects of BP labeling on post-BP scores, and a post hoc symptom control group (n = 55) ensured that symptom levels were representative of the normal population. The majority of subjects in both groups rejected any association between BP labels and symptoms. Data are discussed in the light of Leventhal's models of illness representation.     

The effect of specific hypnotic suggestions on blood pressure in normotensive subjects

Twenty normotensive subjects participated on a voluntary basis in an experiment designed to study the effects of specific suggestions on blood pressure (BP). After an induction procedure, the experimental group received suggestions presumed to be relatively nonactivating, although capable of lowering or raising BP. A control group was used to record the BP changes over time. All subjects met for one session. Eight subjects from the experimental group met for a second session. Both adaptation and induction resulted in significant BP decreases. A specific suggestion to increase BP gave a significant result when compared to the induction point. There was no significant change from induction to the BP decrease suggestion. Both systolic and diastolic BP behaved in the same way. A second experimental session resulted in no significant change compared with the first session. Also, no significant difference was found in suggestibility scores from the first to the second session. The results are in line with previously published studies.     

Effects of test-wiseness training on test anxiety,locus of control and reading achievement in elementary school children

Abstract

Fifth and sixth grade children were randomly assigned to either a control or an experimental condition in a pretest, posttest, delayed posttest design. The experimental group received instruction and practice in test-taking, and the control group received a placebo treatment. Dependent variables were four components of test anxiety, locus of control and achievement. Factor analysis of pretest data supported I. Sarason's four-factor conceptualization of test anxiety (worry, test-irrelevant thinking, tension, and bodily reactions to test taking). Posttest data generally supported the hypothesized treatment effects. As predicted, children in the experimental condition had higher reading scores, greater internality, and less test-irrelevant thinking. The delayed posttest scores indicated a diminished effect on the achievement and internality measures; however, the amount of test-irrelevant thinking remained lower in the experimental condition.     

Ergopsychometry. New methods in experimental psychodiagnosis of pathologic stress reactions

Ergopsychometry--testing under physiological and/or psychological stress--has proved to be increasingly successful in recent years. In particular in sports psychology, in which only physiological stress had been considered, have experimental results been successfully implemented into practice. The fact that some subjects appear unchanged or even yield better results under stress than under stress-free conditions applies not only to physiological stress, but also holds true for psychological stress. These results have consequences for the experimental psychodiagnoses of pathological stress reactions, e.g., with alcoholics or psychosomatic patients. Proceeding from the above hypothesis we investigated 20 gamma-alcoholics (so-called relieve drinkers) and 20 psychosomatic inpatients under stress-free as well as under stress conditions, according to the ergopsychometric approach. The control group consisted of 23 subjects matched with respect to age, sex, and profession. We used a test battery to assess concentration, memory, and choice-reaction as well as the subjective state of activation, stress-coping-mechanisms, and self-concepts. Essentially, the validity of ergopsychometric designs was confirmed by our results. In accordance with our expectations, 27.5% of the experimental group showed increasing efficiency scores, compared to 56.5% in the control group. Possible explanations for the findings can be derived from the assessment of subjective activity, but not from of the personality questionnaires.     

Selective imitation of the passive construction through modeling

Six 4- to 5-yr-old subjects were exposed to five sessions in which an adult model used passive sentences to describe a set of modeling stimuli. Probe stimuli, which the subjects were asked to describe without benefit of modeling and without selective reinforcement were interspersed among modeling stimuli. A matched group of control subjects received probletrials but no modeling trials. Both groups of subjects were subsequently tested on their ability to comprehend active and passive sentence forms. Every subject in the experimental group produced passive sentences on probe trials even though there was considerable variability in the number of passives produced. No control subject produced passives. The modeling procedure increased the comprehension scores of the experimental group above those of the control group though the scores of both groups were above chance. The results were contrasted with earlier studies in which modeling was ineffective in producing passive usage and in which comprehension of the passive was not demonstrated by even older children.     

Cognitive restructuring treatment: A controlled trial with anxious patients

Cognitive restructuring, modified systematic desensitization and a combined treatment (cognitive behaviour modification) were compared with a no-treatment control group, using a simple randomized design. Twenty seven general anxiety out-patients selected from the hospital waiting list were used as subjects. Assessments were made at the beginning and end of treatment, and at follow-up 1 month later. The assessments included two subjective anxiety measures, the Zung self-rating anxiety scale and fear thermometer scores, a behavioural anxiety measure, a measure of cognitive anxiety as estimated by a diary recording of thinking time, fear survey schedule scores and I/E scores.Cognitive behaviour modification was found to be a superior form of treatment, relative to the no-treatment control and the other active treatment groups as assessed by FSS intensity score. The cognitive behaviour modification group showed greater improvement than the cognitive restructuring group on the diary anxiety scores. The results also demonstrated a relationship between outcome and initial severity of condition. The higher the subjects' initial scores on neurotic symptoms and subjective anxiety level, the greater the degree of positive change after treatment. Moreover, subjects with high levels of internal control prior to treatment responded most to therapy.     

Bulimia nervosa: group behavior therapy with exposure plus response prevention

Exposure plus response prevention has been demonstrated to be effective in the treatment of bulimia nervosa. However, when done individually, it is labor intensive and cost-ineffective. In the present study exposure plus response prevention was used in the context of a 6-wk., 12-session behavioral group. In addition to the exposure plus response-prevention component, other techniques included self-monitoring, cognitive restructuring, eating-habit stabilization and problem-solving. Eight bulimic women, vomiting a minimum of five times per week for at least a year, participated in the group. At the end of treatment significant reductions in bingeing and vomiting behaviors were reported by all but one subject, substantiated by significantly lower depression scores (Beck Depression Inventory) and binge-eating scores (Binge Eating Scale). At 6 mo. and 1 yr. posttreatment, 6 of 8 subjects reported averaging less than one binge-purge episode per week, one subject continued unchanged, and one subject had relapsed. A group of wait-list control subjects reported essentially no change in binge-purge frequency over the treatment period. Exposure plus response prevention conducted in a behavioral group context appears to be a cost-effective alternative to individual treatment.     

Individualized behavior therapy for alcoholics: a third year independent double-blind follow-up.

An independently conducted double-blind study providing third year follow-up data for 53 of 70 male alcoholics who served as subjects in an experiment evaluating “Individualized Behavior Therapy (IBT)” techniques is reported. In the original study, subjects were initially assigned to either a controlled drinking or non-drinking (abstinence) treatment goal, and were then randomly assigned to either an experimental group receiving IBT or a control group receiving conventional state hospital treatment oriented towards abstinence. Previously reported results showed that IBT subjects functioned significantly better than control subjects throughout the first year of follow-up. Second year follow-up results found that IBT subjects treated with a controlled drinking goal functioned significantly better than their respective control subjects on a variety of measures, including drinking behavior. Differences between IBT subjects treated with a non-drinking goal and their control subjects did not retain statistical significance during the second year of follow-up. The independently determined follow-up data showed that during the third post-treatment year, subjects in the experimental groups generally functioned better than their respective control subjects. Comparison of the controlled drinking experimental group with its control group showed the significantly better functioning of subjects in the experimental condition on a number of drinking and other life functioning measures. Comparison of the non-drinking groups indicated only one possible difference on the drinking related measures involving a trend for subjects in the experimental condition to abstain more than those in the non-drinker control group. On other life functioning measures, however, subjects in the non-drinking experimental condition showed consistent improvement over their respective control subjects. Both of the controlled drinking groups reported more controlled drinking days than the non-drinking groups throughout the third year follow-up period.
