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.     

Sequential comparisons of relaxation training and biofeedback in the treatment of three kinds of chronic headache or,the machines may be necessary some time of the time

Two studies are reported in which patients with chronic headache, who did not improve significantly as a result of a 10-session, 8-week relaxation training program, were subsequently treated with biofeedback. For the tension headache sufferers, 36% of the relaxation non-responders showed significant improvement with frontal EMG biofeedback training. For those with vascular headaches, 44% of the relaxation non-responders showed significant improvement with thermal biofeedback. Vascular headache patients with combined migraine and tension symptoms did better than those with only migraine. Psychological test scores significantly differentiated successful vs non-successful biofeedback responders.     

Problems with stimulus/response equivalence and reactivity in the assessment and treatment of obsessive-compulsive neurosis

Self-recording was used as part of a comprehensive package of interventions to treat a case of obsessive-compulsive neurosis. The discrepancy between the self-recording data and other indices of improvement provoked consideration of the value of self-monitoring in light of Rachman's (1976) typology of obsessive-compulsives and the three major theoretical explanations of the reactivity of self-monitoring (Nelson and Hayes, 1981). It is hypothesized that self-monitoring may be countertherapeutic and misleading when there is stimulus/response equivalence or a checker type of obsessive-compulsive client.     

Neuroticism and the recall of positive and negative personality information

Recent investigations have shown that high-N scorers preferentially process negative information about themselves. The present experiment investigated: (1) whether this effect is related to, or independent of, the well-established effects of depressed mood on information processing; (2) whether the effect is specific to self-referent information or extends also to information about others; and (3) the mechanism by which the effect occurs. High-N scorers, compared to low-N scorers, recalled more negative information about themselves but not about others, and this effect was independent of depression. In addition, the positive self-referent, but not other-referent, personality information recalled by high-N scorers was more extremely positive than that recalled by low-N scorers. Detailed examination of the data provided evidence that the idiosyncracy in information processing associated with high neuroticism is one of selective attention. The findings are discussed in relation to cognitive vulnerability to depression, certain cognitive-therapy procedures and the effects that a therapeutically-induced change in neuroticism is likely to have on an individual's memory for past emotional experiences.     

Personality and the perception of TV violence

An experiment was carried out to investigate relationships between individuals' personality characteristics and their perceptions of violent TV portrayals. A panel of 40 viewers rated brief violent episodes from five categories of programming, contemporary British crime-detective series, American police series, westerns, science-fiction series and cartoons on eight scales. These responses were then related to viewers' scores on the N, E and P dimensions of the EPQ. Results showed that violent scores from contemporary settings were rated as more serious than scores from non-contemporary and fantastic settings. In addition, viewers exhibited individual differences in ratings of TV violence which were related to certain of their EPQ scores. In particular, high N scorers tended to perceive violence generally, but especially that from contemporary British drama, as more serious than did low N scorers. This study indicates the need to include personality measures in the analysis of audience reactions to TV violence.     

Exposure and communications training in the treatment of agoraphobia

Twenty-one agoraphobics participated in a 6-month study designed to (a) compare imaginal flooding under high- (no sedation) and low- (sedation used) anxiety conditions: (b) examine the long-term effects of imaginal flooding in the absence of further exposure treatment; and (c) explore the impact of communications training on chronic anxiety and panic attacks. A reevaluation of the effects of sedation is presented in this report.Imaginal flooding without sedation was, on the whole, superior to the attention control placebo and imaginal flooding with sedation on therapists' and clients' ratings of fear and avoidance. However, the superiority of the non-drug flooding group cannot be attributed (as was concluded in an earlier report) to higher levels of anxiety across flooding sessions. Rather the drug (methohexitone sodium) appears to have impeded across-session habituation, perhaps by interfering with long-term memorial processes.The effects of imaginal flooding without sedation were stable over 4 months without further exposure treatment. These clients did receive training in solving important interpersonal problems through self monitoring and increased expressiveness. Contrary to hypotheses, not only was no further improvement obtained on fear and avoidance with this treatment, but also anxious mood and panic attacks remained unaffected. It is surprising to note that in-vivo treatment was no more effective than imaginal flooding on fear and avoidance. These and other findings suggest imaginal flooding well warrants further study.     

Individual response patterns and the effects of different behavioral methods in the treatment of agoraphobia

The importance of individual response patterns in agoraphobic patients was examined in the present study. Forty psychiatric outpatients with agoraphobia were assessed in individually relevant natural phobic situations. During this behavioral test their heart rates were measured continuously, and self-ratings of experienced anxiety were made at fixed intervals. On the basis of their reactions in the test situation, the patients were divided into two groups showing different response patterns—behavioral and physiological reactors. Within each group the patients were randomly assigned to one behaviorally-focused method (exposure in vivo, E) and one physiologically-focused method (applied relaxation, AR). The patients were treated individually for 12 sessions. Both treatments yielded significant improvements on most measures; 60% of the E group and 70% of the AR group patients were clinically improved after treatment. The between-group comparisons showed that both treatments did equally well both for behavioral and physiological reactors. Thus, the differential effects for these methods obtained in previous studies were not seen.     

Mood and the self-reference bias in recall

Hypotheses linking a negative recall bias (or negative self-schema) with vulnerability to depression were tested using an experimental mood-induction task. Extent of bias in student subjects was found to be unstable over a 4-month period, but different measures of memory bias within one session were highly correlated. Marginally significant correlations in the expected direction were found between estimates of recall bias and mood state, whether measured at the same or at different times. Change in mood following induction did not relate to change in bias, suggesting that the observed differences in recall are not a simple function of transient mood state alone. Equally, the initial recall bias did not predict the extent of mood shift following induction, as would be expected if a negative self-schema determined ease of mood shift in a negative direction. However, significant correlations were found between negative recall bias and self-reported frequency and severity of depression, lending equivocal support to the negative self-schema model.     

Science and behavior therapy: A survey of research in the 1970s

A representative sample of a decade of contributors to the journals Behavior Therapy, Behaviour Research and Therapy, Journal of Applied Behavior Analysis and the Journal of Behavior Therapy and Experimental Psychiatry was asked to report on their motivations for conducting studies that had been published in that journal. Results indicated that the primary motivation of behavioral researchers was to build on prior research through gathering and analysis of data to illuminate applied-clinical issues and validate treatment procedures. Few researchers reported consultation arrangements or efforts to replicate as their motivation for research. Most respondents described the training model in which they had received their doctoral education as oriented toward a scientist-practitioner approach rather than one that focused primarily on research, therapy or assessment training. Most respondents noted that their philosophy of behavior therapy at the time of the study in question to be applied behavior analysis or social-learning theory with far less being affiliated with a neobehavioristic mediational S-R model or cognitive behavior modification. These results are discussed within the context of the relevance of clinical research in behavior therapy and professional psychology.     

The good,the bad and the mad: Response bias in self-report measures

This study set out to examine the susceptibility of five extensively used, self-report measures to response set bias. Subjects were requested either to fake good, (give a good impression), fake bad, (give a bad impression), fake mad, (give an impression of mental instability) or respond honestly. Subjects who faked good had significantly higher Extraversion, Lie and Social Desirability scores but lowest Neuroticism, Psychoticism and Social Anxiety scores. Subjects who faked bad had significantly lower Extraversion and higher Psychoticism and Social Anxiety scores. Fake mad subjects scored higher on Self-Monitoring and Locus of Control. Four of the eight scales showed significant differences between subjects faking bad and those faking mad. The results are discussed in terms of questionnaire design and respondent's motivation.     

Intermittent low-calorie regimen and booster sessions in the treatment of obesity

The present study investigated two new weight-control strategies: an intermittent low-calorie regimen and intermittent scheduling of booster sessions. A new approach to predicting patient weight loss, based on a pretreatment assessment with a highly-structured eating regimen, was also studied. Forty-eight obese patients were randomly assigned to either a Standard Behavioral weight-control condition or to an Intermittent Low-calorie Regimen (< 750 cal for 2 days/week) condition and to one of two maintenance schedules: a Spaced schedule in which the six booster sessions were held at monthly intervals, or a Massed schedule, in which four of the six meetings were held during the third month. Neither the intermittent low-calorie regimen nor the intermittent scheduling of booster sessions significantly affected weight loss. However, weight loss at 1 year was related to compliance to self-monitoring and to self-reported change in eating habits and exercise. In addition, weight loss at 1 year was related to weight loss during the initial pretreatment assessment period.     

The influence of introversion-extraversion on activity choice and satisfaction among the elderly

The present study investigated the optimum theory of aging. This theory predicts that individuals with different personality types will react differentially to the aging process. In the present study, 60 nursing-home residents were administered the Eysenck Personality Inventory and then randomly assigned to one of two experimental manipulations. Elderly subjects classified as extraverts showed a high level of satisfaction to an experimental manipulation which was of a high activity, interpersonal type; those classified as introverts evidenced more satisfaction with a low activity, non-interpersonal type manipulation. Inspection of records documenting actual participation in programs within the nursing home indicated that introverts were more often involved in low activity, non-interpersonal events whereas extraverts participated more often in high activity, interpersonal events. Implications of these results are discussed in relation to the optimum theory of aging.     

Effect of varying alarm schedules on acquisition and relapse parameters in the conditioning treatment of enuresis

Acquisition and relapse rates for 178 enuretic children were examined as a function of varying intermittent alarm schedules ranging from the standard (100%) bell-and-pad conditioning alarm treatment to a variable-ratio (VR) alarm schedule of 30–59%. Median follow-up time was 25 months. Children who experienced multiple wetting (MW) events beyond the third treatment week experienced twice as many wettings to reach dryness criterion as non-multiple wetting (NMW) children. Approximately one-third of the sample proved to be MW children. Optimal relapse results for NMW children were achieved with the 70–79% VR alarm schedule (10% relapse rate). MW children treated with the standard experienced a 100% relapse rate. For MW children the lowest relapse rates were attained with a 60–69% VR schedule (42% relapse). Older children experienced higher relapse rates than younger children, but age differences were eliminated with a 70–79%, VR alarm schedule. Collectively, the results demonstrate optimal VR intermittent alarm schedules for differen: categories of enuretic children.     

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.     

Sensation-seeking motivation and social-support moderators of the life stress/illness relationship: some contradictory and confirmatory evidence

The present study examined the relationship between measures of life change and reported physical and psychological symptoms as a function of the person's degree of sensation-seeking motivation (SSM) and of social support. A sample of firefighters was tested and showed that, contrary to previous reports, those relatively high in SSM showed a significantly stronger relationship between life change and illness than did those relatively low in SSM. Social support, however, did act to reduce the relationship between change and illness, in line with the evidence from previous investigations.     

The altruistic personality and the self-report altruism scale

This paper is divided into two parts. In the first, the rank order stability of individual differences in altruism across situations is examined and it is found that substantial consistency occurs when due regard is given to the principle of aggregation. In the second, a self-report altruism scale, on which respondents rate the frequency with which they have engaged in some 20 specific behaviors, is found to predict such criteria as peer-ratings of altruism, completing an organ-donor card, and paper-and-pencil measures of prosocial orientation. These data suggest there is a broad-based trait of altruism.     

Therapist factor in the treatment of insomnia

This quasi-experiment attempted to replicate the finding of Turner and Ascher (1979) in contrasting progressive relaxation, stimulus control and paradoxical intention therapies for the treatment of insomnia using clinicians-in-training as therapists. Progressive relaxation and stimulus control were again shown to be effective, paradoxical intention instructions were not. A significant therapist effect was found which is discrepant with previous findings in the field.     

Factor structure of the Menstrual Symptom Questionnaire: relationship to oral contraceptives, neuroticism and life stress

The Menstrual Symptom Questionnaire was administered to initial and cross-validation samples of college-age women. Factor analyses performed on the data from each sample failed to support Dalton's distinction between spasmodic and congestive forms of primary dysmenorrhea. Instead, a more complicated factor structure evolved, closely resembling Webster's findings, with factors representing menstrual pain, pre-menstrual negative affect, pre-menstrual water retention, pre-menstrual pain, menstrual backache and menstrual gastrointestinal symptoms. Oral contraceptive use was negatively related to menstrual pain and backache. Neuroticism scores were positively related to all six factors, and negative life changes to four of these factors, suggesting a role for psychogenic factors in both pre-menstrual and menstrual symptomatology.     

Factors in the referral of children for behavioral treatment: A comparison of mothers of clinic-referred deviant,clinic-referred non-deviant and non-c

The purpose of this study was to compare a non-clinic sample of mothers and children to two groups of clinic-referred children and their mothers. The two clinic-referred groups differed from one another in that the selection criterion for one group of children (Clinic Deviant) was that they were significantly more deviant and non-compliant than the non-clinic group whereas the selection criterion for the second group of children (Clinic Non-deviant) was that they did not differ significantly from the non-clinic group on deviant and non-compliant behavior. Home observations by independent observers and parent questionnaires examining parental adjustment and parental perceptions of child adjustment were completed. The results indicated that both clinic groups perceived their children as more maladjusted than parents in the non-clinic groups perceived their children. Parents of the children in the Clinic Non-deviant group were significantly more depressed than those in the remaining two groups, whereas parents in the Clinic Deviant group issued more vague, interrupted commands than those in the Clinic Non-deviant group. Implications of the findings are discussed.     

Covert sensitization, stimulus relevance and the equipotentiality premise

Covert sensitization and related cognitive aversive techniques have been widely used and reviewed but, to date, the issue of the quality and relevance of the aversive imagery selected has yet to be investigated. In the present study, Ss were given a target substance to consume and then presented with narratives designed to elicit either nausea, anxiety or relaxation. The nausea and anxiety scenes were rated as equally aversive but there was a significant reduction in consumption only within the taste-nausea imagery group. These results are consistent with those obtained from the study of taste aversion in infra-human Ss where taste has been shown to associate preferentially with nausea. The present results call into question the validity of the ‘equipotentiality premise’ in cognition. The implications of these findings for the clinical application and evaluation of covert sensitization are discussed.
