Cognitive consequences of playing brain-training games in immersive virtual reality

The goal of the present study was to examine the effects of playing an immersive virtual reality game that included a collection of gamified cognitive tasks, Cerevrum, on specific components of cognition, including perceptual attention, mental rotation, working memory, visualization, visual field of view, and visual processing speed. Participants completed a pretest of cognitive assessments, played one of the two mini-games within Cerevrum (Stardust or Heroes) for 1.5 hr over three 30-min sessions and then completed a posttest of cognitive assessments and a questionnaire about interest and engagement during the game. An inactive control group completed only the pretest and posttest. Results showed no significant differences among the Heroes group, Stardust group, and control group on the posttest scores, even when controlled for pretest scores. These findings do not support the claim that playing brain-training games for a short period results in transfer of cognitive training to nongame venues.     

Instructor Feedback for College Writing Assignments in Introductory Classes

We compared three instructor feedback protocols to determine whether minimal instructor feedback could improve undergraduate students' writing skills in large introductory classes. The three feedback conditions were specific feedback, nonspecific feedback, and grade only. Sixty community college students participated in the study. Sections of an Introduction to Human Services course were randomly assigned to the three feedback conditions. Students wrote 9 timed essays during the semester. Pretest data were collected from the first essay at the beginning of the semester. Posttest data were taken from the final essay. Data for each student's essays consisted of the number of words written, the number of spelling errors, and the number of syntax grammar errors. Between the pretest and the posttest, students wrote 7 timed essays during class periods. Students in the specific feedback condition received a tally of spelling and grammar errors on grade criteria sheets and the location of the errors marked on their essays. In the nonspecific feedback condition, students received a tally of the errors on their grade criteria sheets but the locations of the errors were not marked on the essays. In the grade only condition, students received feedback on the number of points they had earned for each essay. Significant differences were found for pretest–posttest difference (gain) scores for the proportion of errors to the number of words written between the specific feedback condition and the grade only condition. Specific feedback decreased the proportion of errors to words written. The grade only condition maintained the same proportion of errors to words written from pretest to posttest. Significant differences were also found between difference (gain) scores for total errors between the specific feedback condition and the grade only condition and between the nonspecific feedback condition and the grade only condition.     

Outcomes of Parent Education Programs Based on Reevaluation Counseling

We report two studies in which a parent education program based on Reevaluation Counseling was field-tested on mothers randomly assigned to treatment groups or equivalent, no-treatment comparison groups. The goal was to evaluate the program's viability, whether there were measurable effects, whether those effects were sustained over time, and whether the program was effective among diverse populations. The first study involved middle income, married mothers (n = 25) with at least one child younger than age five. Eleven members of the no-treatment group participated in the program three months later. Pretest, posttest, and follow-up measures included a parental attitude survey and a parenting stress index. The second study involved 18 black mothers with children enrolled in Head Start. Six members of the no-treatment group participated in the program two months later. Added to the pretest, posttest, and follow-up measures were a parent attitude research instrument and a parenting practices questionnaire. Results were replicated within and across studies. Significant effects suggest that the program can reduce parenting-related stress, improve parental attitudes, and encourage authoritative parenting practices, although some effects tend to diminish somewhat over time. The program appears viable with mothers of various social status groups.     

Reading Comprehension: Effects of Individualized,Integrated Language Arts as a Reading Approach with Struggling Readers

This study examined the effects of individualized, integrated language arts as a reading approach on struggling readers' comprehension scores obtained from oral narrative, silent narrative, and silent expository passages at three levels: below-grade, on-grade, and above-grade levels. Students (N = 93) in grades four through eight, who were reading below grade level, participated in the study. Treatment group students (n = 51) received individualized, integrated language arts as a reading approach once a week in place of basal reading instruction. Comparison group students (n = 42) received basal reading instruction for the duration of the study. Multivariate analysis of covariance was used to analyze posttest Analytical Reading Inventory (ARI) comprehension scores. Several statistically significant (p < .001) differences in comprehension performance were found for on-grade-level scores and for above-grade-level scores, but few differences were found between treatment and comparison groups on below-grade-level scores. All statistically significant differences favored students in the treatment group. The findings of the study strongly suggest that the use of individualized, integrated language arts as a method for teaching reading is an effective approach for improving the reading comprehension performance of struggling readers.     

The Effects of Weight Loss Attempts, Exercise Initiation, and Dietary Practices on Health Related Quality of Life

This study (N = 98) randomly placed participants in either a higher protein or American Heart Association diet group with each group initiating an aerobic exercise program. Body composition (BC) was measured using four different methodologies (DEXA, BIA, skinfold, BMI) along with height and weight, while Health-Related Quality of Life (HRQOL) changes were measured using the Medical Outcomes Short Form 36 (SF-36). There were no significant time/diet interactions in HRQOL scores, body fat measures, and weight with the exception of Role-Physical scores (p = .006) with posttest scores higher in participants in Diet 1. Role-Physical scores changed significantly in participants in Diet 1 (p = .0001) and Diet 2 (p = .026) with higher posttest scores in each group. Social functioning had a significant main effect for time in both groups with pretest scores in both diet groups lower than their respective posttest scores (p = .015). HRQOL pretest scores were not significantly different between groups at baseline (p = .56). ANOVA revealed no significant differences in average calories between groups (p = .88). Analysis revealed no differences in exercise in minutes (p = .66) nor statistically significant changes in BC or weight (p = .65). Conclusions: Improvements in HRQOL were demonstrated in two subscales related to physiological and psychological functioning. These novel findings add to literature suggesting that HRQOL, at least concerning social functioning, work and other daily activities (Role-Physical) may improve by initiating an exercise and dietary program even when weight loss or BC improvements have been unsuccessful.     

Rock Stars in Anti‐Drug‐Abuse Commercials: An Experimental Study of Adolescents' Reactions1

Two studies examined adolescents' perceptions and effectiveness of rock stars in antidrug‐abuse public‐service announcements (PSAs). In the pilot study (N= 24 teenagers), adolescents expected rock musicians, and in particular heavy metal musicians, to be drug users. In our experimental study (N= 78 high school students aged 15 to 16 years), one group was shown 4 PSAs produced by Rock Against Drugs, using rock stars Jon Bon Jovi, Aimee Mann, Gene Simmons, and Belinda Carlysle as spokespersons. The comparison group was shown 4 equivalent PSAs that were created using unknown actors selected for their similarity to the rock stars in terms of age, ethnicity, and gender, but without any reference to rock music. PSA ratings were taken on 4 scales: attractiveness, expertness, trustworthiness, and overall PSA rating. Pretest and posttest measures of drug attitudes supported our hypotheses that countermessages from rock stars denormalize the connection between rock music and drugs, and that adolescents respond more positively to PSAs with rock stars than to PSAs without rock stars.     

Building Solutions in Youth: Evaluation of the Human–Animal Resilience Therapy Intervention

The effectiveness of the human-animal resilience therapy (HART) intervention was examined using a randomized comparison group design with youth ages 10–18 (n = 29). Paired samples t-test analyses revealed statistically significant differences between pretest and posttest scores for anxiety, depression, and disruptive behavior inventories for participants in both the treatment and comparison groups. No significant differences were found for the self-concept or anger inventories. An analysis of variance on gain scores of the treatment and comparison groups revealed no between group differences. The implications of the findings are discussed.     

THE RIGORS OF TRAINING EVALUATION: A DISCUSSION AND FIELD DEMONSTRATION1

Training evaluation is one of the most under-researched and neglected areas of industrial/organizational psychology. This article discusses the need for, and feasibility of, utilizing extended-control-group pretest designs in evaluation research; and reports a field application of such a design (the Solomon 4-Group) in an organizational training context. The effectiveness of a basic electricity training program for telephone installer-repairmen was measured, and the potential contaminating effects of pretesting were monitored. The results indicated that the training was potentially effective, but that pretest contaminations were present. To identify the pretest effects it was necessary to go beyond the Solomon model and consider complex interactions involving numerical aptitude level, pretesting and training. Pretest exposure depressed the posttest performance of trained subjects of medium and low numerical aptitude, while facilitating that of medium level untrained subjects. Pretest exposure had no effect on subjects scoring high in numerical aptitude in either the trained or untrained condition. Possible explanations for the moderating role of numerical aptitude are offered, and implications of the findings are discussed relative to applied organizational evaluation efforts and future research.     

Psychotherapeutic Interventions for Symptom Reduction in Veterans With PTSD: An Observational Study in a Residential Clinical Setting

Cognitive processing therapy (CPT) and eye movement desensitization and reprocessing (EMDR) therapy were compared for veterans in a posttraumatic stress disorder (PTSD) residential program (N = 51) who received individual EMDR and group CPT, individual CPT and group CPT, or trauma group exposure (TGE) therapy. Analyses revealed an overall significant difference on posttest measures of the PTSD Checklist for individual EMDR/group CPT and individual CPT/group CPT when compared to TGE, with no significant difference found between EMDR and CPT. Depression scores were significantly decreased between pre- and posttest for patients who received individual EMDR/group CPT. Results support EMDR and CPT as clinically effective and complementary treatments in residential PTSD treatment programs.     

A group treatment program for bulimia nervosa

Seventeen female patients diagnosed as exhibiting bulimia nervosa participated in a shortterm group treatment program. A combination of exposure with response prevention, life skills training, and psychodynamic group interaction was provided. Results in pretest vs. posttest scores on a battery of tests demonstrated improved control over eating behavior and lowered anxiety and depression.     

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.     

A consciousness-sampling analysis of test anxiety and performance

In order to evaluate cognitive-interference, reassertion, and reaction-to-performance models of test anxiety, 82 students completed the Test Anxiety Scale, provided state measures of anxiety just before and after a course examination, described their preparation for the test, and reported thought content and state anxiety up to six times during the test. Test Anxiety Scale scores were predictive of pre- and posttest state anxiety but not performance or problem-solving thought frequency during the test. Thought content was significantly but weakly correlated with performance, which was well correlated with posttest state anxiety but not with pretest anxiety. Pretest state anxiety was virtually uncorrelated with posttest state anxiety, with the correlations gradually declining during the test. Question-answering thought content correlated inversely with anxiety during the test. There was no group for whom anxiety appeared to facilitate performance. Preparation correlated only with performance. The pattern of results appears inconsistent with a cognitive-interference interpretation of test anxiety and suggests that in the naturalistic setting used, anxiety is more clearly an effect than a cause of poor performance.     

The effect of counselling programmes involving expressive activities with semi‐structured groups on self‐concealment levels of adolescents

The aim of this study was to investigate the effects of counselling programmes based on expressive activities with semi‐structured groups, on the self‐concealment levels of adolescents. The research was carried out using a pretest–posttest control group design. The dependent variable of the present research, is the psychological counselling programme conducted with a semi‐structured group based on expressive activities. The research was carried out with 18 6th and 7th grade secondary school students (10 female and 8 male). The Self‐Concealment Scale was used as data collection tool. In this research, the use of nonparametric tests was preferred, as the sample was smaller than 30. Therefore, it was determined whether there is a statistically significant difference between the arithmetic means of the experimental and control groups’ pretest, posttest and trail test scores by use of Wilcoxon signed‐rank test, to determine the effects of a psychological counselling programme with semi‐structured group based on expressive activities. Also, it was determined whether there was a statistically significant relationship between the pretest, posttest and trail intervention scores received by the intervention and control group students from the Self‐Concealment Scale, using Mann–Whitney U test. The research results revealed that the “psychological counselling programme based on expressive activities with semi‐structured groups” was significantly effective in alleviation of self‐concealment levels, and this effect was also maintained in follow‐up evaluations. The obtained results are discussed in the light of related literature findings and recommendations are proposed accordingly.     

Locus of control and perceived alcohol ingestion in performance of a fine motor skill

To investigate the influence of locus of control on a fine motor corrdination task where subjects had ingested or believed that they had ingested alcohol, 60 men who were enrolled in introductory psychology and scored in the upper or lower thirds of the population on Rotter's I-E Scale (30 external and 30 internal scorers) were randomly assigned to one of three treatment conditions: a control group (no alcohol expected/no alcohol received), an alcohol group (alcohol expected/alcohol received), and a placebo group (alcohol expected/no alcohol received). Pretest and posttest measures of performance on the Purdue Pegboard Test were obtained from all subjects. Subjects in the control groups were given three 6-oz. (177.4-ml) glasses of fruit punch over a 35-min. waiting period between pretest and posttest on the Purdue Pegboard. The alcohol groups drank a sufficient number of similar glasses (usually three) to produce a 0.1% measure on a breathalyzer before completing the posttest on the Purdue. Pegboard. The placebo groups were told that they were drinking an alcohol-based drink but were served three glasses of a nonalcoholic, rum-flavored fruit drink. These groups were also told that they measured 0.1% on a breathalyzer. Control groups, both internal and external scorers, showed essentially no change from pre- to posttest on the Purdue Pegboard. The alcohol groups, on the other hand, both internal and external scorers, showed a significant decrement in performance. The internal-placebo group did not differ from the two control groups and showed no decrement in performance.(ABSTRACT TRUNCATED AT 250 WORDS)     

Mood state changes of women as a function of regular aerobic exercise

The present study examined mood states of aerobic exercisers before and after completing a 15-wk. program. The subjects (ages 18 to 36 yr.) were 86 women enrolled in activity classes at a large state school in the southeast. Subjects were initially classified according to previous exercise habits. Analysis indicated both groups of frequent and infrequent exercisers were similar in mood states. Participation in regular exercise did not significantly change or enhance the mood states from pretreatment measures. Pretest measures of mood states provided poor prediction of posttest measures, indicating extreme variability in subjects' scores.     

A Rational-Emotive Treatment program with conduct disorder and attention-deficit hyperactivity disorder adolescents

This study investigated the effects of a 12-week treatment program, based on Rational-Emotive Therapy, with conduct disorder (CD) and attention-deficit hyperactivity disorder (ADHD) adolescents. Two independent homogeneous CD (N=12) and ADHD (N=12) groups were selected on the basis of the DSM-111-R and use of methylphenidate. The dependent variables were irrational thinking, depression, and anger. Lecture, discussion, and theYou Can Do It!Motivational Program video were used in the treatment intervention. Discriminant function analysis of pretest scores revealed that 96% of the students were correctly classified (CD=100%, ADHD=92%). Multivariate analysis of pre-posttest scores revealed that the CD group significantly changed on all dependent variables, while no significant differences were found with the ADHD group. A comparison of posttest scores on the measure of irrational thinking revealed that the CD group accepted responsibility for their upsetness and were more willing to change than the ADHD group. The results of the study are interpreted in terms of the distinguishing characteristics of each group.G. Barry Morris Ph.D., is Director of the Canadian Institute for Rational-Emotive Therapy. He is a Fellow and training supervisor in Rational-Emotive Therapy, a professor at the University of Saskatchewan, a licensed psychologist, and is engaged in private practice.     

Adjustment for the Total Number of Responses in Calculating the Rorschach Apperception Type

In order to adjust for total responses (R) on the Rorschach, apperception (location) scores arc expressed as percentages of R. An alternative procedure is recommended in which adjustments are the differences between obtained scores and those predicted from the regression of the scores on R. Standardization Ss were 200 male and female normals, ages 20 to 40. Percentages of these Ss falling within certain ranges of adjusted scores are given. Caution is recommended in making inferences about apperception types obtained by extrapolating beyond the range of R in the standardization group. Preliminary results obtained by applying these adjustments to disturbed adult and children's groups suggest that the distributions of adjusted scores tend to approximate the score distribution of the standardization group.     

Reducing reactive aggression in schoolchildren through child,parent, and conjoint parent‐child group interventions: An efficacy study of longitudinal outcomes

This study was the first to evaluate the effectiveness of three different group interventions to reduce children's reactive aggression based on the social information processing (SIP) model. In the first stage of screening, 3,734 children of Grades 4–6 completed the Reactive–Proactive Aggression Questionnaire (RPQ) to assess their reactive and proactive aggression. Respondents with a total score of z ≥ 1 on the RPQ were shortlisted for the second stage of screening by qualitative interview. Interviews with 475 children were conducted to select those who showed reactive aggression featuring a hostile attributional bias. Finally, 126 children (97 males and 29 females) aged 8 to 14 (M = 9.71, SD = 1.23) were selected and randomly assigned to one of the three groups: a child group, a parent group, and a parent–child group. A significant Time × Intervention effect was found for general and reactive aggression. The parent–child group and child group showed a significant drop in general aggression and reactive aggression from posttest to 6‐month follow‐up, after controlling for baseline scores, sex, and age. However, the parent group showed no treatment effect: reactive aggression scores were significantly higher than those in the child group at 6‐month follow‐up. This study has provided strong evidence that children with reactive aggression need direct and specific treatment to reconstruct the steps of the SIP involving the selection and interpretation of cues. The intervention could help to prevent severe violent crimes at the later stage of a reactive aggressor.
