Speed analyses of stimulus equivalence.

The functional substitutability of stimuli in equivalence classes was examined through analyses of the speed of college students'' accurate responding. After training subjects to respond to 18 conditional relations, subjects'' accuracy and speed of accurate responding were compared across trial types (baseline, symmetry, transitivity, and combined transitivity and symmetry) and nodal distance (one- through five-node transitive and combined transitive and symmetric relations). Differences in accuracy across nodal distance and trial type were significant only on the first tests of equivalence, whereas differences in speed were significant even after extended testing. Response speed was inversely related to the number of nodes on which the tested relations were based. Significant differences in response speed were also found across trial types, except between transitivity and combined trials. To determine the generality of these comparisons, three groups of subjects were included: An instructed group was given an instruction that specified the interchangeability of stimuli related through training; a queried group was queried about the basis for test-trial responding: and a standard group was neither instructed nor queried. There were no significant differences among groups. These results suggest the use of response speed and response accuracy to measure the strength of matching relations.     

Academic Careers of Gifted Women

As part of a larger study concerning academically gifted college women, gifted freshman women who graduated (723) were compared with those who did not graduate (526) on certain academic variables. Graduates took an average of 12.6 quarters to complete their degrees. Average length of attendance before departure for Nongraduates was 5.8 quarters. Graduation with honors was achieved by 51.9 per cent of the Graduates. Graduates and Nongraduates differed significantly in GPA (3.06 to 2.50), contact with the Counseling Bureau (43.6 to 30.9 per cent), and in major fields of study. More Graduates had Liberal Arts (CLA) “social science,” CLA “interdepartmental and double,” Education, and Home Economics majors. More Nongraduates had CLA “English, linguistics, and languages,” CLA “natural science and mathematics,” and Business Administration majors. These results are discussed in relation to findings of the larger study concerning personality characteristics and vocational interests of gifted women, and a follow-up study of the Nongraduates.     

Exercise as psychotherapy

The use of exercise as a psychotherapeutic agent is reviewed. The benefits of exercise are considered to impact both physiological processes and psychological factors such as self-esteem and more efficacious self-talk. The possibility of the use of exercise as an adjunct to both pharmacotherapy and psychotherapy is suggested.     

How do Relationship Stability and Quality Affect Wellbeing?: Romantic Relationship Trajectories,Depressive Symptoms,and Life Satisfaction across 30 Years

Lifecourse theory scholars focus on how individuals traverse social roles, such as marriage, parenthood, and employment, in similar and different ways across their lives. This study examined one specific role trajectory: romantic relationships. This study examined men’s and women’s (N?=?3617) relationship status and quality across approximately 30 years. Using second-order latent class analysis, results showed four predominant relationship role trajectories: (a) Multiple Transitions, (b) Stable Marriage with High Conflict, (c) Stable Marriage with High Satisfaction, and (d) Marriage to Divorce/cohabitation. These relationship role trajectories differed on two aspects of quality of life: life satisfaction and depressive symptoms. Individuals in the Multiple Transitions trajectory consistently reported poorest quality of life; however, those in the Multiple Transitions and Stable Marriage with High Conflict trajectories were the only that reported decreases in depressive symptoms over 30 years. Relationship satisfaction poorly differentiated the trajectories compared to relationship conflict and stability.
