Group differences and first principal-component loadings in the Hawaii family study of cognition: a test of the generality of ‘Spearman's hypothesis’

The generality of Spearman's hypothesis that varying differences between whites and blacks on various tests of mental ability are correlated with their g-loadings was tested by analyzing group data from the Hawaii Family Study of Cognition. Data from the three largest ethnic groups tested in the Hawaii Study (Americans of Japanese, Chinese or European ancestry; total N = 5333) were subjected to a principal-component analysis and the first principal component was used as a measure of g. Ethnic group and generation (parent-offspring) differences on 15 tests of specific cognitive abilities were then correlated with their first principal-component loadings. In general, correlations between ethnic group differences and g-loadings are smaller than those recently reported for white-black differences by Jensen (1983); however, those between generation differences and g-loadings are larger. Ethnic group differences on first principal-component scores in the Hawaii Study are less than parent-offspring differences; thus, the correlation between group differences on tests of mental ability and their g-loadings may be a function of the magnitude of the group difference for general mental ability. Because a group difference on g requires group differences on tests which load on g, an observed group difference in general mental ability may necessarily result in a correlation between group differences on individual tests and their g-loadings.     

Cardiac response as an index of the effect of aversion therapy

Recent research shows that aversion conditioning produces conditioned aversions to target stimuli. Conditioned aversions are manifest in the following posttreatment changes in Ss' responses to target stimuli: increased negative evaluations, decreased contact or consumption, and increased phasic heart-rate responses (HRRs). Research on aversion therapy for additive disorders reveals that HRR is a particularly important index of therapeutic change as it is predictive of latency to relapse to drug use. We speculate that aversion conditioning increases Ss' fear and repugnance of target stimuli, that HRRs accurately reflect such defensive responses and that magnitude of defensive response is positively related to latency to relapse. In addition to defensive responding, we believe that HRRs may reflect coping-response or active-avoidance information processing.     

The treatment of nocturnal bruxism using contingent EMG feedback with an arousal task

Nocturnal electromyographic (EMG) recordings of masseter muscle activity were performed before and after treatment on 10 heavy bruxism subjects. Treatment consisted of giving the subjects an auditory feedback signal during sleep which occurred when they clenched with moderate force. Each subject additionally had to perform an arousal task every time the signal occurred. Nine of 10 subjects demonstrated a significantly decreased EMG activity using a contingent auditory feedback signal, combining it with an arousal task.     

Efficacy of self-instructional training for reducing children''s anxiety in an evaluative situation

Fifty-six fourth-grade children were categorized as either high or low in trait anxiety and then assigned to a self-instruction treatment, minimal-treatment, or no-treatment control condition. At both pretest and posttest, the subjects recited a memorized poem while being videotaped with the expectation that they would be judged on their performance. State anxiety measures, a behavior rating of anxiety, a measure of performance accuracy and the time involved in reciting a poem were obtained at both pretest and posttest. Contrary to expectation, the self-instructional training resulted in subjects' exhibiting greater signs of behavioral anxiety, subjects' hurrying through the task (taking less time to recite the poem) and high trait-anxiety subjects' reporting more state anxiety while anticipating reciting the poem. Correlational analyses indicated that trait anxiety was significantly related to the measures of state anxiety and the behavior rating of anxiety but not to performance accuracy.     

Return of fear: The role of rehearsal

The assumption was made that return of fear could be brought about by recalling highly fear-provoking material. Two conditions were contrasted in the design, one of which was high- vs low-intensity treatment and the other rehearsal of phobic material vs distraction following treatment. The experimental conditions yielded no significant results at the end of the rehearsal/distribution period. However, a week later at retest, partial return of subjective fear was observed in the ‘distraction’ groups and elevated heart-rates in the high-intensity groups. It was concluded that rehearsal of fear-provoking material following treatment constituted a prolongation of the latter and was therefore therapeutic. Implications of results with regard to within and between-session habituation are discussed.     

Treatment of adolescent agoraphobics: Effects on parent-adolescent relations

Three adolescent agoraphobics, accompanied by their mothers, were treated in a small group. Treatment consisted of self-initiated exposure, panic management and cognitive restructuring, with the parent acting as co-therapist. Measures of adolescent-parent relationships were administered as well as measures of agoraphobia. As with adult agoraphobics treated with their spouse, results indicated a parallel relationship between phobia and family relations; that is, as phobia improved, the relationship improved. Unlike adult agoraphobics, adolescents were unable to comprehend that agoraphobic fears concerning health or dying were unrealistic. This interfered with motivation and underscored the need of the parent as a co-therapist.     

The development of reflection-impulsivity: further data

The MFF20 was administered to 617 children aged 7–12yr. The resulting development trends for latency and errors suggest errors decrease to about age 10 yr then level off while a corresponding, though less dramatic, increase in latency was observed. These results were obtained without evidence of ceiling or floor effects or any evidence of a decrease in the relationship between latency and errors after age 10 yr, in contrast to those obtained by Salkind and Nelson (1980).     

Behavioral training for myopia: generalization of effects

The present study assessed generalization of training effects using a video computer system (VCS) as a training medium for modifying acuity. Eighteen myopic volunteers were matched according to pre-training acuity and assigned to either fading and feedback training group or a practice only control. Subjects were pre- and post-tested on three measures: the Snellen Letter Chart, a Behavioral Acuity Test and a performance test with the VCS. Compared to controls, trained subjects displayed significant improvements in acuity on the Behavioral Acuity Test. These results suggest that training effects generalize to untrained stimuli. Implications for the clinical implementation of behavioral training procedures for modifying myopia are discussed.     

Antidepressant medication in the treatment of agoraphobia: A critical review

The present article critically examines research on the use of antidepressants in treating agoraphobia. A number of studies have shown certain classes of antidepressant medication, namely tricyclic antidepressants and MAO inhibitors, to have beneficial effects on certain aspects of the agoraphobic syndrome. However, these studies must be interpreted with caution in light of two major methodological shortcomings, i.e. sole reliance on paper and pencil outcome indices and the confounding of the pharmacological effects of the drug with exposure to feared situations. Recent research, aimed at correcting for these methodological problems, seriously question the efficacy of antidepressant pharmacotherapy by itself as a treatment for agoraphobia. Moreover, it is argued that the disadvantages of drug treatments namely agoraphobics' reluctance to take medication, physical side effects and relapse upon withdrawal of the medication, caution against their routine use in clinical practice.     

Strength of the nervous system and augmenting-reducing: Paradox lost

Two conflicting viewpoints were identified regarding the relationship between sensation seeking and subjective response to stimulation: (a) that sensory augmenters are high sensation seekers compared with sensory reducers (the view of Zuckerman and Buchsbaum); and (b) that it is the reducer rather than the augmenter who is the high sensation seeker (the view of Petrie and Vando). Proponents of the first approach measure Augmenting-Reducing through the use of the average cortical-evoked response, while advocates of the second position use Petrie's version of the Kinaesthetic Figural Aftereffects Test or Vando's Reducer-Augmenter Scale. It is argued that the disagreement is semantic and results from the differences in method of measurement. It is further argued that most, if not all, of the research findings may be accommodated within the framework of strength-of-the-nervous-system theory which distinguishes between two dimensions,sensitivity andfunctional endurance. The implications for future research are pointed out.     

Bulimia nervosa: a descriptive and therapeutic study

This study examined a sample of 24 Ss who met strict criteria for a diagnosis of bulimia nervosa. Assessments were made on: (1) demographic characteristics, (2) eating attitudes and behaviour and (3) personality measures. The effectiveness of two types of therapeutic intervention (cognitive-behavioural group therapy vs cognitive-behavioural group therapy plus specific behavioural instruction) was examined in a baseline, therapy intervention, follow-up design.The group was characterized prior to therapy by high N, Depression and Anxiety and low Self-esteem scores compared with control group data. Following therapy, Depression and Anxiety scores were significantly lower and Self-esteem scores higher, whereas N scores remained high. Binge-purging frequencies were significantly reduced in some of the Ss but the reduction could not unequivocally be attributed to the therapeutic interventions. The pattern of results suggested that bulimia nervosa (defined by a binge-purging pattern in association with high neuroticism) should be distinguished from bulimia (defined by a binge pattern not related to purging or high neuroticism) and that DSM-III should be revised to reflect this distinction. A theory is advanced to account for the rapid association of binging and purging in Ss high in neuroticism but not in Ss low in neuroticism.     

Binge eating and outcome of behavioral treatment of obesity: a preliminary report

A survey was carried out of binge-eating behavior in a group of 44 patients who had completed group behavioral treatment for obesity. Obese binge eaters, defined by DSM-III criteria for bulimia, lost significantly less weight immediatedly posttreatment and at 6-month follow-up than non-binge eaters.     

Complementary pairing of handicapped workers with compensatory skills: a strategy to increase independence

Although the right to and the beneficial psychological effects of productive employment by the handicapped are well documented, many potential workers remain unemployable because of the nature of their handicapping conditions. This study is an experimental investigation of the effect on job performance of pairing handicapped persons with complementary skills. Workshop productivity was measured for two pairs of workers, each consisting of a cerebral-palsied person and a mentally-retarded partner. Using a multiple-baseline design with a reversal component, production on a packaging task was assessed during individual work and paired cooperative work. The combination of the cerebral-palsied workers' ability to provide reinforcement and the retarded workers' production skills resulted in a significant increase in productivity. The potential extension of this strategy to individuals with these and other disabilities is discussed.     

The evidence for interactionism in psychology : A critical analysis of the situation-response inventories

A great deal of the evidence for interactionism in personality psychology arose out of the situation-response (S-R) studies of which there are now over 30. This paper examines closely the evidence for traitism, situationism and interactionism that arises from these studies. Nearly all of the published studies are tabulated, reanalysed and detailed criticisms of the more influential papers are offered. Serious problems are apparent in the methodology and analyses of these studies as well as in the conclusions drawn from them. It is argued that these studies have brought as much confusion as clarity to an area of research bedevilled by both conceptual and methodological problems.     

The assessment of depression in children: The internal structure of the child depression inventory (CDI)

In the present report three separate studies of childhood depression were conducted. First, the internal structure of the Child Depression Inventory (CDI), with 216 children representing various ethnic groups with equal numbers of boys and girls, was evaluated through a factor analysis and by various internal-reliability measures (e.g. split-half reliabilities, Pearson correlations of each item to the total score). Four factors were established and internal reliability of the scale proved to be high. The relationship of the factor structure of the CDI to Kendell's Type A and B categorization of depression are discussed. In Study 2 the relationship of demographic variables to the CDI using the same group of children described for Study 1 was employed. Evaluating the characteristics of depression across age, sex and so on in children has not been frequently studied, and was deemed appropriate for the present investigation. Age proved to be a significant factor in depression scores although race and gender did not. With respect to age, older children tended to display more symptomatology. Comparisons of depressed children to nondepressed children also showed that age was a factor in the obtained scores, and range of severity in both groups. Depressed children differed from nondepressed children on all 27 items indicating that all the items on the CDI seem to be measuring a unitary concept. Study 3 compared CDI scores to a measure of social behavior, the Matson Evaluation of Social Skills with Youngster (MESSY). Seventy-six children (36 girls and 40 boys), ages 4–10 yrs $\text{(}\text{X}\text{?}\text{= 7)}$ were evaluated. Appropriate Social Skills was negatively correlated with childhood depression, and Inappropriate Impulsive/Assertiveness was positively correlated with depressive features described under the factor Guilt/Irritability. The implications of these data for further research on assessment, differential diagnosis and evaluation of treatment research are discussed.     

Cognitive-behavioral treatment of agoraphobia: paradoxical intention vs self-statement training

Twenty-six agoraphobics were randomly assigned to either Paradoxical Intention (PI) or Self-Statement Training (SST) which consisted of 12 weekly 90-min group sessions with 4–5 patients per group. Major assessments were carried out at pre-treatment, 6th week and 12th week of treatment, and at 1- and 6-month follow-ups. Measures included clinical ratings of severity of condition, phobia, anxiety and depression. Furthermore, a behavioral test was administered during which changes in subjective units of discomfort and cognitions were assessed. The results indicated statistically-significant improvement over time with both treatments. ANCOVAs performed revealed superior effects on several agoraphobia measures for the PI condition at post-treatment. However, by the 6-month follow-up assessment, the groups were equivalent due to marked improvement during the follow-up phase in the SST condition. Cognitive changes were marked by a decrease in self-defeating statements without concomitant increase in coping statements. These results and recommendations for future research are discussed.     

Two factors of restraint: concern for dieting and weight fluctuation

Factor analysis of the Restraint Scale produced two replicated factors: Concern for Dieting and Weight Fluctuation. Concern for Dieting reflects heightened attention to and emotional association with eating. Weight Fluctuation reflects extent of previously-experienced weight gain and loss. Weight Fluctuation was more highly positively correlated with indices of overweight status than was Concern for Dieting. Concern for Dieting was positively correlated with Public Self-Consciousness and Social Anxiety while Weight Fluctuation was not. Both versions of Restraint were weakly and inversely correlated with Body Image, although this relationship was mediated by degree of overweight status. The findings indicate that the two factors are sufficiently distinct to preclude combination into a single scale. Furthermore. Weight Fluctuation appears to be the more promising subscale for future research.     

The reduction of anxiety in children: a comparison of the effects of 'systematic desensitization in vitro' and 'systematic desensitization in vivo'

Twenty-four children between the ages of 5 and 10. selected on the basis of fear of water, as determined by parents and swimming teachers, were divided into two experimental groups and one control group. One of the experimental groups was treated with four sessions of in vitro desensitization (gradual imaginal exposure to fear evoking stimuli plus relaxation), followed by four sessions of in vivo desensitization (real-life exposure to fear evoking stimuli plus relaxation). The other group received eight sessions of in vivo desensitization. The control group took part only in the tests, which were administered at the commencement of treatment, after four sessions, and at the end of the course of treatments. In testing, a behavior observation record was used to score the subject's behavior in the given situation; in addition, two teacher's records were used, in which swimming teachers recorded their evaluation of the subject's anxiety in each situation.Better results were achieved by desensitization in vivo than by desensitizalion in vitro or by the control procedure. No differences were found between the latter two groups. It could not be demonstrated that desensitization in vitro increased the effectiveness of subsequent desensitization in vivo     

Assertion training: the effectiveness of a comprehensive cognitive--behavioral treatment package with professional nurses

The purpose of the study was to evaluate the effectiveness of a comprehensive cognitive-behavioral treatment package with a professional population of registered nurses using multiple self-report and role-play measures. Twenty-six self-referred registered nurses were randomly assigned to either a Treatment or Control group. The treatment package consisted of five weekly 2-hr sessions of group assertion training using the cognitive-behavioral model of Lange and Jakubowski. The Assertiveness Self-statement Test, the Rathus Assertiveness Schedule, the Adult Self-expression Scale, two Likert scales and role-play were used to evaluate changes over time. The results indicated: (1) the nurses in both groups at Pretreatment were clearly subassertive; (2) by Posttraining the Treatment-group members increased significantly their assertiveness as indicated on the self-report tests; (3) Treatment-group members had successfully maintained their improved assertiveness by the 2-month Follow-up; (4) the role-play ratings paralleled and supported the self-report results, but not at significant levels; (5) there was strong empirical support for the social validity of the treatment package; and (6) there was a high degree of treatment credibility for the cognitive-behavioral Assertion-training group. Overall, the results indicate clear support for the effectiveness of a broad-based cognitive-behavioral treatment package for treating subassertive behavior in a professional population of registered nurses.     

Pain sensitivity and coping strategies among dysmenorrheic women: much ado about nothing

Samples of spasmodic, congestive and combined dysmenorrheic women and non-dysmenorrheic women were subjected to an ischemic pain procedure to measure their pain threshold, pain tolerance and self-reported pain. Cognitive and behavioral strategies that subjects had spontaneously used during the pain procedure were later assessed. A classification system was derived for categorizing subjects' responses to the interview and questionnaire used in this assessment. Contrary to previous claims that dysmenorrheic women may be hypersensitive to pain, no differences in pain sensitivity were discovered among the four groups of subjects. A few differences in cognitive and behavioral strategies did emerge, but these were of insufficient magnitude to contend that dysmenorrheic women are disadvantaged in their strategies for coping with pain.
