Previous evaluations of the Circumplex Model's curvilinear hypothesis using FACES instruments have yielded conflicting results. A review of the different research procedures and samples used in those investigations revealed that none of the studies had samples large and/or heterogenous enough to test the curvilinear hypothesis adequately. The present study(More)
In this article, the hypothesis that some individuals confronted with an intellectual evaluation use a lack of preparation as a "self-handicapping" strategy (Jones & Berglas, 1978) was studied. Sex and both level and certainty of self-esteem were examined in regard to the self-handicapping strategy of lack of effort. Subjects were 54 men and 54 women,(More)

Levels of test anxiety, Type A and Type B coronary-prone behavior, fear of failure, and covert self-esteem were studied as predictors of self-handicapping performance attributions for college women who were placed in either a high- (N = 49) or low- (N = 49) evaluative test or task situation. We hypothesized that test anxiety. Type A or Type B level, and(More)
On a pediatric bone marrow transplant unit, hematologist-oncologists, nurses, social workers, psychiatrists, psychologists, and others on the team deal with children and adolescents whose cancers are either treatable by marrow transplantation or are ultimately fatal. Contrary to original assumptions, many children and families cope well, especially in(More)

The roles of density-dependent larval survival and cannibalism of larvae as potential mechanisms of population regulation in the newt (Notophthalmus viridescens dorsalis) were evaluated in laboratory and field experiments. In laboratory containers, adults cannibalized larvae and large larvae cannibalized smaller larvae. In artificial ponds, larval survival(More)
