Type A behaviour and psychophysiological arousal

The "coronary prone" or Type A behaviour pattern, characterized by e.g., hard-driving competitiveness, impatience and aggressiveness, is associated with elevated systolic blood pressure and catecholamine secretion during challenge. In experiments at our laboratory, elevated psychophysiological arousal was found in Type A subjects during understimulation, but not during active performance on a self-paced reaction time task. Results suggest that differences in cardiovascular and behavioural reactivity between Type A and B persons tend to be related to the pace of the environment to which they are exposed. Studies of antecedents of Type A behaviour in children show that "Type A children" respond to challenge with a greater increase in sympathetic arousal than "non-Type As". This suggests the possibility that genetic dispositions and/or conditioned sympathetic reactivity play an important role in the development of the Type A behaviour pattern.     

Reliability of psychophysiological assessment

In order to assess the reliability of psychophysiological recording, 15 subjects were assessed on multiple response measures (forehead EMG and forearm flexor EMG, heart rate, skin resistance level, hand surface temperature and cephalic vasomotor response), under multiple stimulus conditions (baseline, self-control, cognitive and physical Stressors), on multiple occasions (Days 1, 2, 8 and 28). Three forms of reliability coefficients were computed for each response measure: coefficients on absolute scores, coefficients on change scores from baseline to stressful conditions and coefficients on percent change from baseline. Only frontal EMG appeared to have consistently high absolute reliability coefficients, with hand surface temperature having high reliability if sessions are repeated within 1 week. Heart rate was less consistently reliable. Treating the responses as relative measures did not increase their reliability; indeed, hand surface temperature was completely unreliable when examined in this fashion. Implications of this study for behavioral medicine, biofeedback and anxiety-based disorders research, as well as Lang's tripartite response system model of fear and emotion, are discussed.     

Test-retest reliability of psychophysiological assessment

Thirty subjects participated in a study of the test-retest reliability of five psychophysiological assessment procedures: habituation. Quiz Electrocardiogram, anger imagery, aversive slides and startle. The procedures were presented in identical fashion, 2 weeks apart. Skin conductance level and response, heart rate, vasomotor response, skin temperature, frontalis and forearm electromyogram, respiration rate. and systolic and diastolic blood pressure were recorded continuously. The following analyses were performed on Test-Retest data: correlations, baseline changes, profile similarity, and stability of ranked standardized physiological scores. Significant but modest Test-Retest correlations were found for skin conductance level and response, skin temperature, respiration rate, heart rate and systolic blood pressure. Absolute scores were more often stable than change scores. All baselines were stable from Test to Retest. Four baselines and four test procedures had Test-Retest Profile Similarity Index scores indicating reliability. Chi-square analyses of Retest ranks of standardized physiological scores showed that the two most and least responsive measures accounted for Test-Retest stability. Conclusions were: (a) Psychophysiological response patterns are reliable for baselines and procedures, and single psychophysiological measures (especially absolute scores) are moderately stable; (b) Traditional (correlational) estimates of the reliability of single psychophysiological responses are limited by individual-response stereotypy, but multivariate analysis of response pattern provides a better index of reliability.     

The psychophysiological correlates of risk recognition among victims and non-victims of sexual assault

This study examined the psychophysiological correlates of risk recognition in sexual victimization. Victims and non-victims of sexual assault listened to a hypothetical date rape interaction and were asked to indicate the point at which the man had become sexually inappropriate. Subjective and objective (physiology) measures of responding as well as a measure of risk recognition in reaction to the date rape scenario were analyzed to evaluate both between and within-subjects' differences. Results showed that, relative to non-victims, victims of sexual assault displayed significant differences in risk recognition as well as both subjective and objective measures of physiological reactivity. Overall, the results indicate that altered physiological responding to relevant threat cues may be related to individuals' ability to identify and react to threatening sexual situations.     

The modification of sexual fantasies: A combined treatment approach to the reduction of deviant sexual behavior

A consideration of the literature on the behavioral therapy of sexual deviations suggests that the direct modification of fantasies will provide an effective treatment method. A combination of two procedures for modifying the content of sexual fantasies is outlined and the results of treatment with twelve patients using this combined approach are described. The hypothesis that the modification of fantasies would have a direct effect on both deviant behavior and attitudes toward deviant material, was not unequivocally supported. However, the program had eliminated deviant behavior in all subjects by the end of treatment, and this was maintained at follow-up in at least 75 per cent of the patients.     

Relationships between musical structure and psychophysiological measures of emotion

Psychophysiological studies with music have not examined what exactly in the music might be responsible for the observed physiological phenomena. The authors explored the relationships between 11 structural features of 16 musical excerpts and both self-reports of felt pleasantness and arousal and different physiological measures (respiration, skin conductance, heart rate). Overall, the relationships between musical features and experienced emotions corresponded well with those known between musical structure and perceived emotions. This suggests that the internal structure of the music played a primary role in the induction of the emotions in comparison to extramusical factors. Mode, harmonic complexity, and rhythmic articulation best differentiated between negative and positive valence, whereas tempo, accentuation, and rhythmic articulation best discriminated high arousal from low arousal. Tempo, accentuation, and rhythmic articulation were the features that most strongly correlated with physiological measures. Music that induced faster breathing and higher minute ventilation, skin conductance, and heart rate was fast, accentuated, and staccato. This finding corroborates the contention that rhythmic aspects are the major determinants of physiological responses to music.     

The development of attention to simple and complex visual stimuli in infants: Behavioral and psychophysiological measures

The study of visual attention in infants has used presentation of single simple stimuli, multi-dimensional stimuli, and complex dynamic video presentations. There are both continuities and discontinuities in the findings on attention and attentiveness to stimulus complexity. A continuity is a pattern of looking that is found in the early part of infancy that remains throughout adulthood. A discontinuity is an emerging sensitivity to the content of the information in the stimulus presentations and alterations in patterns of attention based upon stimulus comprehensibility. The current paper reviews some of these findings with particular application to complex video presentations.     

Buddhism and behaviour modification

There has been in recent years a growing interest in the similarities between Buddhism and the principles and practice of behaviour modification. Mikulas, for example, has pointed out many similarities and argued for greater integration. The present paper examines the literature of Early Buddhism with a view to assessing how far its approach is similar to that of behaviour modification and to examine some specific behaviour-change techniques used in Early Buddhism in relation to similar techniques developed and used by modern behaviour therapists. The implications of these findings are discussed in relation to theory and clinical practice.     

Attitudes to sex, sexual behaviour and enjoyment of humour

Freudian (1905 Wien; Der Witz und seine Beziehung zum Unbewuβten. Deuticke) and Salience (Goldstein, Suls and Anthony, 1972; The Psychology of Humor. Academic Press, New York) theory make opposite predictions about the effects of attitudes to sex and sexual behaviour on appreciation of sex humour. Male and female students (N=115) answered a questionnaire of attitudes toward sex, a sexual behaviour inventory (Eysenck, 1976; Sex and Personality. Open Books, London) and a humour test. The results generally supported a positive correlation between appreciation of sex humour and the sex scales (sexual libido, satisfaction, experience and pleasure), although the resulting pattern was very complex. Separation of sex humour according to the jokes structure yielded different predictor patterns. Funniness of humour based on nonsense correlated most frequently and most highly with the sex scales libido, experiences and pleasure. Low sexual satisfaction, low permissiveness, and prudishness were correlated with aversiveness of all types of humour. Furthermore, it was hypothesized that these variables are better predictors of enjoyment of sexual humour than the more general factors of conservatism and toughmindedness (T) which turned out to be potent predictors in a recent study (Ruch and Hehl, 1986; Person. individ. Diff. 7, 861–874). It turned out that the predictive sex scales were located on the toughmindedness axis and were thus as predictive of sex humour as T itself. A refinement of the salience hypothesis was undertaken.     

The psychotherapy adaptation and modification framework: application to Asian Americans

Although effective treatments for many mental disorders have been developed, little research has been conducted to determine whether these interventions are effective in treating those from diverse backgrounds. Recent reports have suggested that ethnic minorities are less likely to receive quality health services and that they evidence worse treatment outcomes when compared with other groups. To improve care for those from diverse backgrounds, Western-developed psychotherapies may need to be culturally modified or adapted to become more effective in treating ethnic minorities. This article addresses the need for adapting psychotherapy and provides a conceptual framework for making such modifications. The psychotherapy adaptation and modification framework model is applied to recent Asian American immigrants as an illustrative example. However, it may also serve as a point of departure to adapt therapies for other ethnocultural groups.     

Culture-fair cognitive ability assessment: information processing and psychophysiological approaches

Valid assessment with diverse populations requires tools that are not influenced by cultural elements. This study investigated the relationships between culture, information processing efficiency, and general cognitive capacities in samples of Caucasian and Mexican American college students. Consistent with the neural efficiency hypothesis, pupillary responses (indexing mental effort) and detection accuracy scores on a visual backward-masking task were both significantly related to the Wechsler Adult Intelligence Scale-Revised (WAIS-R) Full Scale scores. These measures of information processing efficiency were similar in the two groups. However, they were related only to Caucasian American, but not to a comparable sample of Mexican American, students' WAIS-R scores. Therefore, the differential validity in prediction suggests that the WAIS-R test may contain cultural influences that reduce the validity of the WAIS-R as a measure of cognitive ability for Mexican American students. Information processing and psychophysiological approaches may be helpful in developing culture-fair cognitive ability measures.     

Self-reports, spouse ratings, and psychophysiological assessment in a behavioral medicine program: an application of the five-factor model.

This article describes the integration of the five-factor model into assessment procedures used with 109 patients in an outpatient behavioral medicine program. The population, program, assessment techniques, and general findings are explored. A case history involving a psychophysiological disorder is utilized to demonstrate the utility of a taxonomy of personality traits. The NEO-PI, a five-factor instrument, is integrated with other assessment techniques to assist in diagnosis, rapport building with the patient, tailoring treatment techniques and goals to the individual's intrapersonal and interpersonal dynamics, and predicting relative success and compliance with noninvasive self-regulation procedures and psychotherapy.     

Comparing measures of cognitive bias relating to eating behaviour

Consumption of and/or abstinence from substances with a high reward value (e.g. heroin, marijuana, alcohol, nicotine, certain foods) are associated with cognitive biases for information related to the substance. Such cognitive biases are important since they may contribute to difficulties in controlling intake of the substance. We examine cognitive biases for stimuli related to food. For the first time, we concurrently employ and compare five conceptually distinct measures of cognitive bias (dot probe, emotional Stroop, recognition, EAST, explicit attitudes). Contrary to expectations from current theory, the relation between the cognitive measures was weak and evident only in certain subsets of the population sample, as defined by gender and emotional‐, restrained‐ and external‐eating characteristics of our participants. We discuss some methodological implications of our findings. Copyright © 2008 John Wiley & Sons, Ltd.     

Child-focused behavioral assessment and modification

Argues that behavioral principles have been translated into practice with children too literally and that a more integrative framework is required to guide assessment and treatment. The framework advocated is Staats's (1996) psychological behaviorism. This is a consistently behavioristic, positivist paradigm, using multilevel theory to emphasize the integration of social learning, developmental, and personality principles. Psychological behaviorism thus allows for a much more expansive approach than has typically been the case within child behavior therapy. Given the complexity of this perspective, I selected four broad tenets of the theory and suggested their implications for clinical contexts. The further translation from clinical models to specific clinical practices is quite difficult but may yield more flexible and substitutable practices than do unidimensional treatment outcome studies. Of special importance, the principles demonstrate how children themselves can retain the central focus of child behavioral assessment and modification. Specific practices still need to be constructed according to an understanding of the multiple sources of influence on children as well as the culture of childhood itself.
