The treatment of tension headache—II. EMG ‘normality’ and relaxation

A selected group of patients complaining of severe and chronic tension headache (without muscular abnormality) were given a short 3-week course of relaxation treatment. Half of the subjects received progressive relaxation instructions, while the other half received relaxation plus calming imagery. Both groups showed substantial improvements in pain behaviour and in pain experience. The improvements were synchronous and still present at the 6–8 week follow-up assessment. Although no significant differences were found between the groups, the addition of imagery appeared to produce larger improvements on a number of measures. These results were compared with those reported obtained in a previous biofeedback study and the implications of both the studies were discussed with respect to tension headache and its treatment.     

Validation of the Differential Emotions Scale in 613 mothers

Mothers (N=613) with infants who took the Differential Emotions Scale (DES) were compared in a cross-validation study by factor analysis to 957 high school and college students. Despite differences in factor-analytic technique, similarities in factor structure suggested that the DES discriminates the majority of fundamental emotions as posited by Izard.Robert Emde is supported by Research Scientists Award No. 5 KO5 MH 36808 and NIMH Project Grant No. 2 RO1 MH 22803.

The Barnum effect in a group setting

The present study expands the typical Barnum effect paradigm by investigating reactions to feedback in a group setting. People initially participated in a group experience (8 per group), and then were given bogus positive or negative feedback (the favorability manipulation) purportedly prepared by either the group leader or another group member (the source status manipulation). The answerability manipulation led participants to believe that they either would or would not have to share their reactions to the feedback with the person who prepared it. Positive feedback was rated as more accurate and accepted more highly than the negative feedback, though no differences in recall of either the positive or negative feedback emerged. Additionally, a pattern of results revealed that the feedback from the group leader generated greater perceived accuracy, acceptance, and recall than did feedback from another group member. Implications for the impact of feedback given by a high status person in group settings are discussed.     

The fakability of the personal orientation dimensions: evidence for a lie profile

The resistance of the Personal Orientation Dimensions (POD) to deliberate attempts at creating a favorable impression was investigated. Two groups of college students were used: (a) 21 students completed the POD under standard instructions, then received information about actualization, and completed the POD again under instructions to Create a very good impression; (b) 21 students completed the POD under standard instructions, then received information not related to actualization, and completed the POD again under instructions to create a very good impression. An analyses indicated that providing students with information about actualization did not facilitate their ability to create a favorable impression on the POD. The POD profiles produced by both groups changed significantly, and in a similar direction from pretest to posttest. Evidence is presented suggesting the existence of a "lie profile" which distinguishes deliberate attempts to create a favorable impression on the POD. These findings provide support for the resistance of the POD to deliberate attempts at creating a favorable impression.     

Piaget's data and spearman's theory—An empirical reconciliation and its implications for academic achievement

A hierarchical simple structure factor solution was obtained for item scores from a psychometrized battery of Piagetian-type tasks individually administered to 660 kindergarten children. At the first level of factors were the Piagetian theoretical entities of seriation, classification, conservation of number, and temporal and spatial reasoning, with numeration loading on seriation and classification as indicated by the theory. At the second level were two factors identified as Piaget's logicomathematical and infralogical operations. A third-level factor was identified as a g factor. The association of the Piagetian-type tasks with kindergarden and first grade academic achievement was through the third-level g factor. The second-level factors appeared to be similar to Vernon's k:m and v:ed but, like the first level factors, made no important contribution to predicted achievement above that contributed by the g factor. A socioeconomic factor made no unique contribution to predicted first grade achievement. It was concluded that the Piagetian concrete operations variables have no unique role in the prediction of kindergarten or first grade academic achievement.     

The Use of Multitrait–Multimethod Data for Detecting Nonlinear Relationships: The Case of Psychological Climate and Job Satisfaction

Previous monomethod research has found mixed support for nonlinear effects between certain job characteristics (e.g., job autonomy, job complexity) and outcome variables (e.g., job performance). We hypothesized that these weak nonlinear findings may be due to the prevalence of monomethod research that can lead to a lack of complete measurement and/or introduce common methods variance, either of which may mask the true shape of relationships. Using hierarchical regression analyses and a multitrait–multimethod (MTMM) research design, we found strikingly different results between monomethod and MTMM data when considering the relationships between three psychological climate variables and job satisfaction. While the monomethod results mirrored earlier inconclusive findings, the MTMM data indicated that nonlinear equations explained significantly more of the relationship between all three climate dimensions and job satisfaction. These results suggest that the use of MTMM data allows one to more effectively test for nonlinear effects. Furthermore, these nonlinear results suggest that the format of employee questionnaires should probably change from asking how much an employee has of certain constructs to asking does the employee want more or less of these constructs.     

The Miraculous Choice Argument for Realism

The miracle argument for scientific realism can be cast in two forms: according to the miraculous theory argument, realism is the only position which does not make the empirical successes of particular theories miraculous. According to the miraculous choice argument, realism is the only position which does not render the fact that empirically successful theories have been chosen a miracle. A vast literature discusses the miraculous theory argument, but the miraculous choice argument has been unjustifiably neglected. I raise two objections to Richard Boyd's defense of the latter: (1) we have no miracle free account of the emergence of take-off theories and (2) the anti-realist can account for the non-miraculous choice of empirically successful theories by attributing mere empirical adequacy to background theory. I argue that the availability of extra-empirical criteria that are arguably truth conductive but not theory-laden suffices to answer (1), and the unavailability of extra-empirical criteria that are conductive to empirical adequacy but not necessarily to truth (and are also not theory-laden) constitutes to reply to (2). The prospects for a realist victory are at least somewhat promising, on a controversial assumption about the rate at which empirically successful theories emerge.
