GROUP HOMOGENEITY, RANGE RESTRICTION, AND RANGE ENHANCEMENT EFFECTS ON CORRELATIONS

Recently, the issue of range enhancement effects on correlations has been raised as a potential criticism of correction for range restriction in validity generalization. While adding to or deleting from a sample can affect both the variance and correlation in the sample, increases or decreases in individual differences in an intact sample resulting from such factors as history, maturation, training, and experience will not necessarily affect correlations. If such changes in individual differences do occur in concurrent validation studies, the most likely result will be an underestimate of the unrestricted validity.     

Eating Disorders on Campus: A Procedure for Community Intervention

Concern for students with eating disorders and concern for the environment served as the catalyst for the development of a procedure for responding to eating disorders. The procedure, which relies heavily on residence hall staff, is presented here, with emphasis on training, prevention, and issues in implementation.     

The Instability of Philosophical Intuitions: Running Hot and Cold on Truetemp

A growing body of empirical literature challenges philosophers' reliance on intuitions as evidence based on the fact that intuitions vary according to factors such as cultural and educational background, and socio-economic status. Our research extends this challenge, investigating Lehrer's appeal to the Truetemp Case as evidence against reliabilism. We found that intuitions in response to this case vary according to whether, and which, other thought-experiments are considered first. Our results show that compared to subjects who receive the Truetemp Case first, subjects first presented with a clear case of knowledge are less willing to attribute knowledge in the Truetemp Case, and subjects first presented with a clear case of non-knowledge are more willing to attribute knowledge in the Truetemp Case. We contend that this instability undermines the supposed evidential status of these intuitions, such that philosophers who deal in intuitions can no longer rest comfortably in their armchairs.     

Attachment style and coping resources as predictors of coping strategies in the transition to parenthood

The relations among adult attachment style, coping resources, appraised strain, and coping strategies were examined in a prospective study of married couples having their first child (N= 92). Attachment and coping resources were measured during the second trimester of pregnancy, and parenting strain and coping strategies were assessed when the babies were about 6 weeks old. Results supported a theoretical model proposing that attachment is predictive of coping resources and appraised strain, and that attachment, resources, and strain are predictive of coping strategies. Results also highlighted the complexity of associations among attachment, stress, and coping: Gender differences in mean scores and predictive associations were obtained, and some interactions were found between resources and strain in predicting coping strategies. The findings support the utility of integrating theories of attachment and coping in explaining couples’adjustment to important developmental transitions.     

Psychological characteristics of Russians

Concerning national characteristics, previous work (Peabody, 1985) had generally shown agreement between student judgements and other information. The Russians were a dramatic exception. New evidence comes from ingroup judgements, where Russians were judged impulse-expressive. This disagrees with earlier outgroup judgements, but agrees with other evidence about Russian national character.     

Justified Judging

Traditional approaches to epistemology have sought, unsuccessfully, to define knowledge in terms of justification. I follow Timothy Williamson in arguing that this is misconceived and that we should take knowledge as our fundamental epistemological notion. We can then characterise justification as a certain sort of approximation to knowledge. A judgement is justified if and only if the reason (if there is one) for a failure to know is to be found outside the subject's mental states; that is, justified judging is possible knowing (where one world accessible from another if and only if they are identical with regard to a subject's antecedent mental states and judgement forming processes). This view is explained and defended.
