The role of hyperventilation in panic disorder: a response to Ley (1991)

Ley (Behaviour Research and Therapy, 29, 301–304, 1991) provided a reinterpretation of experimental findings on the efficacy of breathing retraining plus cognitive restructuring in reducing the symptomatology of patients with panic disorder with agoraphobia which were presented in a 1989 article in this journal. On the basis of his reinterpretation, they concluded that our findings supported the central role of hyperventilation in panic attacks. Ley's arguments are discussed and we conclude that his reinterpretation provides new arguments against a hyperventilation theory of panic. Furthermore, recent evidence from empirical studies does not support a central role for hyperventilation in panic attacks.     

The validity of the Crites model of career maturity

To test the validity of the Crites model of career maturity, career maturity and noncareer maturity measures were administered to 312 ninth graders and to 200 technical college students. Scores on all measures were intercorrelated and factor analyzed. The results show that, as predicted, most of the Career Choice Competencies have more in common with each other than they have with Career Choice Attitudes; Career Choice Competencies are fairly highly positively related to each other; Career Choice Attitudes and Career Choice Competencies have more in common with each other in grade 9 than they do in the post-secondary grades; and there is a relationship between career maturity and sex and race of ninth graders and technical college students. The results do not support the hypothesized multidimensional structure of the Crites model or the hypothesis that variables in the Crites model have more in common with each other than they have with noncareer maturity variables. Discussion includes several possible explanations for failure to support the Crites model, and suggestions for further research.     

A comparison of two sex-role androgyny measures in a study of sex-role identity for incarcerated delinquent and nondelinquent females

A sample of 100 incarcerated delinquent females and 100 nondelinquent female matched for age and socioeconomic status were compared on three aspects of sex-role identity. The Bem Sex-Role Inventory and the PRF ANDRO scale were used to assess sex-role androgyny; the Traditional Family Ideology scale was used to assess sex-role attitudes; and several questions concerning heterosexual relationships were asked. Correspondence between the two androgyny measures was moderate at the interval level of measurement and poor at the nominal level. Repeat offenders were significantly higher than first-time offenders and nondelinquents on the BSRI masculine scale; a significantly higher percentage of repeat offenders were classified as androgynous by the BSRI. No differences were observed using the PRF ANDRO scales. Heterosexual relationships were more important in the lives of delinquent females on both friendship and helping dimensions.     

Complex analyses of variance: General problems

Problems in applying the analysis of variance are discussed. Emphasis is placed on using the technique to understand the data. The scale of the dependent variable is important for the analysis. Crossed and nested categories must be recognized. The error terms in the analysis depend on whether the classes of each independent variable are (1) all out of a few or (2) a few out of many. To simplify the analysis, mean squares should be aggregated with their error term when they are less than twice its size. An illustrative example is discussed in detail.Prepared in connection with research sponsored in part by the Office of Naval Research, in part by the Educational Testing Service, and in part by Lincoln Laboratory, a center for research operated by Massachusetts Institute of Technology with the joint support of the U. S. Army, Navy, and Air Force.     

Social Support. Physiological Processes, and Health

Social relationships serve important functions in people's everyday lives. Epidemiological research indicates that supportive relationships may also significantly protect individuals from various causes of mortality, including cardiovascular disease. An important issue is how social support influences such long-term health outcomes. In this article, we review evidence indicating that social support may influence mortality via changes in the cardiovascular, endocrine, and immune systems. These data suggest that it may be worthwhile to incorporate social-support interventions in the prevention and treatment of physical health problems.     

Responding to allegations of scientific misconduct

Institutions in France are not yet well prepared to respond to allegations of scientific misconduct. Following a serious allegation in late 1997. INSERM,* the primary organization for medical and health-related research in France, began to reflect on this subject, aided by scientists and jurists. The conclusions have resulted in establishing a procedure to be followed in cases of alleged misconduct, and also in reinforcing the application of good laboratory practices within each laboratory. Guidelines for authorship practices and scientific assessment must also be considered. Even though each institution must remain responsible for responding to allegations of scientific misconduct within its doors, INSERM would like to see national, European, and international co-ordination about the methods of such response. Institut National de la Santé et de la Recherche Médicale (eng. French National Medical Research Institute) is known as INSERM. An earlier version of this paper was presented at a symposium, Scientific Misconduct: An International Perspective, organised by The Medical University of Warsaw, 16 November, 1998.     

An automatic micropipette fluid dispenser

An automatic device for repeated dispensation of a precisely controlled amount of fluid is described. The device employs a repeating micropipette powered by an electric motor geared to a rack-and-pinion drive. In our particular application, thirsty rats work for 0.2-ml shots of water delivered to a metal spout connected to a drinkometer circuit. This arrangement permits the recording of both volumetric intake and the number of licks directed at the spout.     

Inclusiveness of identification among farmers in The Netherlands and Galicia (Spain)

In this paper we discuss inclusiveness of identification among farmers in Galicia (Spain) and The Netherlands. Identification with three nested categories—farmers in the local community, farmers in the country, and farmers in Europe was assessed among 167 Dutch and 248 Galician farmers at three points in time: winter of 1993/94, winter 1995 and fall 1995. Our findings suggest that inclusiveness reduces the level of identification. However, the observed patterns of identification were more complex than inclusiveness per se can account for. Borrowing from the common ingroup‐identity model, functional and socialization models of identity formation, and a model of politicized collective identity we formulated hypotheses about patterns of identification that were to be expected. On the whole our findings supported our theoretical reasoning. Galician farmers appear to identify much less with farmers in their country and Europe than Dutch farmers do. Inclusiveness of identification appears to be linked to experience with national and supranational political institutions. More political knowledge and involvement appear to generate more inclusive patterns of identification. Among Galician farmers evaluation of the agricultural policy of the European Union is negatively related to identification with farmers in Europe, among Dutch farmers the two are positively related. Finally, more inclusive identities seem to be more politicized. Copyright © 2004 John Wiley & Sons, Ltd.     

Discounting and the role of the relation between causes

This research investigates how the relation between two causes (i.e. whether they co‐occur or not) affects the likelihood to discount one of them. In two experiments, two causes were either systematically paired together (positive relation), were paired with many other causes (independent relation), or were never paired together (negative relation). The results indicate that discounting of one of the causes (target cause) depends on the relation with the other cause (alternative cause) and the order in which the alternative cause was presented and produced the outcome alone. If information on the independent outcome of the alternative cause came prior to the joint outcome of the alternative and target cause (forward order), then discounting of the target cause occurred regardless of the relation between the two causes. If, however, information on the independent outcome of the alternative cause came after the joint outcome of the alternative and target cause (backward order), then discounting of the target cause occurred mainly when there was a positive or negative relation between the causes, but not when there was an independent relation. The degree of backward discounting given a positive or negative relation was largely identical. These results are consistent with the retrospective revaluation hypothesis of Dickinson and Burke ( 1996 ) and shed new light on the role of the relation between causes on discounting.
