An on-line program to calculate respiratory sinus arrhythmia amplitude

A variety of evidence shows that the amplitude of respiratory sinus arrhythmia (RSA)—the peak-to-peak variations in heart rate caused by respiration—is a valid and reliable index of para-sympathetic cardiac control. An on-line program to calculate RSA amplitude on a breath-by-breath basis is described. The validity of the RSA amplitude values obtained through the computer pro-gram were tested in two studies. From the first one, the correlations between RSA amplitude and a set of cardiorespiratory variables, under both rest and auditory stimulation conditions, are reported. In the second study, the effect of atropine administration on the RSA amplitude, under both rest and mental load conditions, was examined. The results of both studies are con-gruent with predictions and suggest the usefulness of the software.     

The Case(s) of Gordon Allport

ABSTRACT Gordon Allport has frequently been criticized for advocating the use of idiographic studies but undertaking only one such study himself. This article describes Allport's work on the case of Marion Taylor, an unpublished study that clearly contributed to his later work on the case method. The unfinished Taylor case materials suggest that Ada Allport was an important collaborator in Allport's work with individual cases. The case of Taylor is compared with the later case of Jenny Masterson using Allport's rules for the preparation of case studies in order to shed light on Allport's ambivalence regarding case studies.     

The value of possessions in compulsive hoarding: Patterns of use and attachment

Hoarding behavior, patterns of use of possessions, and emotional attachment to possessions were examined among a sample of female undergraduates and a sample of community volunteers. Hoarding behavior was associated with a decreased frequency of use of possessions and excessive concern about maintaining control over possessions. Furthermore, high scores on the hoarding scale were associated with higher levels of perceived responsibility for: (1) being prepared; and (2) the well-being of the possession. Hoarding was also associated with greater emotional attachment to possessions and to the reliance on possessions for emotional comfort. The implications of these findings for the definition of hoarding are discussed.     

Human Resource Management Group,University of Nottingham,UK

In a new series of regular reports, research groups active in personnel psychology from a number of countries will present a briefing on work-in-progress. In the first in this series, the HRM Group at the Department of Psychology, University of Nottingham, describe their ongoing work into organization change and training validation, employee socialization, computer-based testing, and personality test construction and assessment centre validation.     

Indirect modes of aggression among women of Buenos Aires,Argentina

This study utilizes the construct indirect aggression to investigate aggressive behavior among middle class Argentine women and men by administering an attitude and self-report survey to 95 inhabitants of Buenos Aires and by analyzing ethnographic interviews and observations conducted over a nine month period in 1992. An examination of sex roles in Argentina, including machismo and marianismo, provide a cultural context for interpreting aggression. Factor analyses revealed the presence of indirect aggression (e.g., social manipulation, gossip, exclusion) in addition to verbal and physical aggression. Survey and ethnographic findings converge in suggesting that women employ more indirect aggression than men, while men utilize more physical aggression. While competition and aggression are salient elements of social life for both sexes, women and men tend to favor different approaches. The findings are compared with the literature on female aggression from other cultural settings. We conclude that cultural and evolutionary perspectives elucidate aspects of female aggression.We would like to thank the Ford Foundation for providing the financial support to make this research possible. We would also like to thank Patricia de Gyldenfeldt and Debbie Bandura for their endless contributions with translations, ideas, and help in general. Finally, we would like to thank Eckerd College, la Universidad del Salvador, and Michael Hobson for their base of support, all those in Argentina, especially Agueda, Andrea, Carmen, Cecilia, Claudio, Daniela, Heidi, Ingrid, Javier, Julio, María, Mariela, Roberto, and Victor, who offered their enthusiastic assistance and ideas, and Victoria Burbank, Ayala Gabriel, and the anonymous reviewer for their helpful suggestions.     

MENSTRUAL JOY The Construct and Its Consequences

Fifty female college students participated in a study of women's health. In a counterbalanced design, half of the participants completed the Menstrual Joy Questionnaire (MJQ) and the Menstrual Attitude Questionnaire (MAQ) in the first testing session. A week later they completed the Menstrual Distress Questionnaire (MDQ) and the Menstrual Attitude Questionnaire. The other participants completed the MDQ and MAQ in the first session and the MJQ and MAQ in the second. A multivariate analysis of variance revealed that those who received the MJQ first reported more positive cyclic changes on the MDQ and more positive attitudes on the MAQ. A follow-up study of 40 college students examined their responses to the MJQ. Participants reported that they were surprised or incredulous; most had not previously considered positive aspects of the menstrual cycle. Thirty percent reported that the MJQ had caused them to look at menstruation in a different way.     

Coping with peer stressors and associated dysphoria: Acculturation differences among Chinese-American children

The purpose of this study was to explore the role of acculturation in coping with stress among 264 Chinese-American children. The results confirmed that the subjects used a variety of coping strategies including diversion, suppression, problem solving, minimization, and retaliation and that certain coping strategies influenced the dysphoria experienced as a result of peer stress. High acculturated children used retaliation significantly more often than their low acculturated counterparts and retaliation was found to be associated with less dysphoria for the high acculturated group. In contrast, low acculturated children who utilized suppression tended to report less dysphoria. Contrary to the hypothesis that general self worth would reduce the relationship between peer stressors and dysphoria, it had no bearing on the association for either acculturated group. The hypothesis that greater perceived social competence would lessen the association between peer stressors and dysphoria also failed to be supported by the data. In fact, for the high acculturation group higher social competence was actually associated with more reported dysphoria. In general, the results suggested that the adaptiveness of particular coping strategies may be influenced by acculturation level and that social competence plays a complicated role in the stress and coping process. Implications for counsellors are discussed.     

A program to assess baroreceptor cardiac reflex function

This paper describes a computer program for the noninvasive evaluation in the time domain of the part of the baroreceptor reflex that relates blood pressure to interbeat interval from spontaneous hemodynamic patterns in which the reflex is operating. The program obtains the sensitivity of the baroreceptor reflex (slope of the regression line between the interbeat interval and systolic blood pressure in msec/mmHg) and an index of the baroreceptor power to regulate cardiac activity. These statistics are obtained differentially both when the systolic blood pressure is increasing and when it is decreasing. The results obtained by using this software during a mental load task were compared with those obtained through spectral analysis.
