What motivates stunt men?

If confrontation with danger is related to fear, and fear is considered to be the motivation for avoidance behavior, the question remains why certain people seek confrontations with danger. The present study, part of a larger one, is concerned with confrontation with actual danger, as in dangerous sports or voluntarily chosen dangerous professions. It reports the results of interviews with six stunt men. These results partly support the hypothesis of Zuckerman on sensation-seeking personality features: The subjects appear to be eager for varied experience and relatively unconcerned with negative consequences of their actions. The ability to stand the strains and to concentrate under riskful conditions shows up as a further important characteristic of stunt men. The major reward that constitutes the motivation for engaging in the stunting profession appears to consist of being able to meet the challenges involved, with increased self-esteem, receiving acclaim, and monetary profit as secondary rewards. Ability and motivation thus are inextricably intertwined.With acknowledgment to Prof. Nico Frijda, without whose support this article would not have been written and would not have acquired its present form.     

Representational guidance of action production in observational learning: a causal analysis

This experiment tested the hypothesis that the number of model presentations and verbal coding of modeled actions affect reproduction accuracy through their effect on cognitive representation. Subjects viewed a complex action pattern either two or eight times with or without verbal coding to highlight the dynamic structure of the component actions and their temporal sequencing. They then received, in order, a recognition test and a pictorial-arrangement test to assess the accuracy of their cognitive representations of the modeled actions. Subsequently, all subjects were tested for their ability to reproduce the action pattern from memory. Results showed that increased exposure to modeled actions enhanced the accuracy of both the cognitive representation and the behavioral reproduction. Verbal coding also increased cognitive and reproduction accuracy, but only when combined with multiple opportunities to observe the modeled actions. A causal analysis confirmed that the effects of multiple exposures and verbal coding were entirely mediated by changes produced in the accuracy of cognitive representation.     

Inflated responsibility in obsessive-compulsive disorder: Psychometric studies of a semiidiographic measure

An excessive sense of responsibility has been attributed a key role in recent models of obsessive-compulsive disorder (OCD). This study presents the development and initial validation of the Responsibility Questionnaire. Three hundred ninety-seven volunteer adults participated in the study. The Responsibility Questionnaire demonstrated adequate stability over a 6-week interval. Correlation analysis showed that responsibility was significantly related to obsessive-compulsive symptoms, thought suppression, irrational beliefs, and obsessional thoughts. Results are discussed in terms of current models of OCD and the implications for future research.This study was conducted by the first author under the supervision of the second author in partial fulfillment of the requirements of the Maîtrise de Psychologie degree at Université Laval.

The Impact of Breast Cancer and Its Treatment on Marital Functioning

This article reviews the research that has examined the impact of breast cancer and its treatment on the patient's marital relationship. Breast cancer and its treatment affect not only the patient, but also her intimate partner and their relationship, including their communication, sexual relationship, and role identities. Both positive and negative effects of the experience have been identified. Predictors of marital adjustment following breast cancer are also reviewed, including demographic factors, illness factors, and characteristics of the couple. The strongest predictor of the impact of the cancer experience appears to be the premorbid quality of the relationship. A methodological critique identifies limitations of past research, and suggestions for future research are addressed. Finally, two theoretical paradigms that may account for the impact of breast cancer on relationships are discussed.

A psychiatrist's reflections on the workers' compensation system

In the ‘looking-glass land’ of workers' compensation psychiatry, symptoms are not always what they seem, treatments may have little or no positive effect, and workers' claims of continued disability may puzzle and perplex. Disability is in part a social role, and a simple medical model cannot explain the complex interactions of sociology, psychology, anthropology, medicine, economics, and law characteristic of the workers' compensation system. Psychiatrists functioning within and reciprocally shaped by this semi-adversarial system will rarely encounter an ‘ideal’ patient. Factors in all areas of workers' lives, including those integral to the workers' compensation system, influence their movement along a health-illness, ableddisabled axis. This paper identifies a number of interacting factors that may prolong, or even subvert, the recovery process following a work-incurred injury or illness.     

Simple software for impedance cardiography

Simple software techniques for the digital analysis of impedance cardiography data are described. The software digitizes simultaneous impedance and ECG signals, averages these signals over time on a beat-by-beat basis, processes the averaged signals to locate relevant features, and computes heart rate, stroke volume, and cardiac output for the averaged period. The source and executable code, written in Pascal for a PDP-11 with standard peripheral addressing and a VT125 graphics terminal, is available from the authors.     

Sex-role expectations of socially desirable first names

This study was an attempt to investigate the relationship between child-naming practices and the perpetuation of traditional sex-role expectations of masculine and feminine behaviors. It was hypothesized that desirable male and female first names would be rated as more sex-typed the more frequently they occurred in the culture. No relationship on a cross-sex-typed effect was predicted for undesirable first names. Psychology undergraduates (N=149) nominated desirable and undesirable male and female first names. The frequency of nomination was correlated with ratings of masculinity or femininity of the names, and the results supported the hypotheses. A significant correlation was found between frequency and degree of stereotypy of first names rated as desirable, but no effect was found for undesirable first names. These results were discussed in terms of role-conflict theory. Secondary issues raised were the use of androgynous first names and the effects of first names on affirmative action procedures.     

Heart rate and self-report changes accompanying different types of relaxing imagery

Two groups of 10 subjects were instructed, following appropriate training, to evoke different types of relaxing imagery for a total of five 30 s trials. For one group the instruction stressed response elements in the image, for the other stimulus elements. A third, control group of 10 were invited to relax by any means they considered appropriate. No specific imagery instructions were given here. Heart rate was recorded throughout and ratings of sleepiness were made by subjects at the end of each trial. Analogue mood scales were completed pre- and post-experimentally. While the self-report measures intimated an increase in feelings of relaxation and sleepiness over the course of the experiment, no group differences were observed. For heart rate, however, group differences were apparent. Overall, heart rate change during trials took the form of cardiac acceleration. However, while the two imagery groups demonstrated more or less sustained acceleration throughout trial periods, the acceleration observed initially in the control group showed a pronounced linear decline with a net deceleration being recorded toward the end of each trial. The imagining of response or stimulus elements did not differentially affect heart rate. These data imply that the process of imagining constitutes a more important influence on heart rate in these circumstances than image type or affective content.     

Learning on a response continuum: Comparison of a linear change and a functional learning model

Two reinforcement schedules were used to compare the predictive validity of a linear change model with a functional learning model. In one schedule, termed “convergent,” the linear change model predicts convergence to the optimum response, while in the other, termed “divergent,” this model predicts that a subject's response will not converge. The functional learning model predicts convergence in both cases. Another factor that was varied was presence or absence of random error or “noise” in the relationship between response and outcome. In the “noiseless” condition, in which no noise is added, a subject could discover the optimum response by chance, so that some subjects could appear to have converged fortuitously. In the “noisy” conditions such chance apparent convergence could not occur.The results did not unequivocally favor either model. While the linear change model's prediction of nonconvergence in the divergent conditions (particularly the “noisy” divergent condition) was not sustained, there was a clear difference in speed of convergence, counter to the prediction inferred from the functional learning model. Evidence that at least some subjects were utilizing a functional learning strategy was adduced from the fact that subjects were able to “map out” the relation between response and outcome quite accurately in a follow-up task. Almost all subjects in the “noisy” conditions had evidently “learned” a strong linear relation, with slope closely matching the veridical one.The data were consistent with a hybrid model assuming a “hierarchy of cognitive strategies” in which more complex strategies (e.g., functional learning) are utilized only when the simpler ones (e.g., a linear change strategy) fail to solve the problem.
