Standardized Effect Sizes For Moderated Conditional Fixed Effects With Continuous Moderator Variables, Todd Bodner

Psychology Faculty Publications and Presentations

Wilkinson and Task Force on Statistical Inference (1999) recommended that researchers include information on the practical magnitude of effects (e.g., using standardized effect sizes) to distinguish between the statistical and practical significance of research results. To date, however, researchers have not widely incorporated this recommendation into the interpretation and communication of the conditional effects and differences in conditional effects underlying statistical interactions involving a continuous moderator variable where at least one of the involved variables has an arbitrary metric. This article presents a descriptive approach to investigate two-way statistical interactions involving continuous moderator variables where the conditional effects underlying these …

Workshop Synthesis: Measuring Attitudes And Perceptions In Quantitative Surveys, Kelly Clifton, Juan Antonio Carrasco

Civil and Environmental Engineering Faculty Publications and Presentations

This workshop engaged participants in discussion about issues in incorporating qualitative information, namely attitudes, perceptions, and other psychological-social factors into transport research and analysis. There are many challenges to collecting this information from respondents. This synthesis summarizes the workshop presentations and discussion where participants identified the various types of information desired, reviewed the current challenges in conducting this type of data collection, made recommendations for practice, and outlined an agenda for future research.

Reactions To Disability: An Empirical Investigation Of Their Nature And Structure, Hanoch Livneh, Richard F. Antonak

Counselor Education Faculty Publications and Presentations

This paper describes the initial steps toward the construction of an experimental, multidimensional inventory to measure reactions to physical disability. The Relations to Impairment and Disability Inventory (RIDI) was developed to provide information on eight patterns of psychosocial reactions to disability, namely: shock, anxiety, denial, depression, internalized anger, externalized hostility, acknowledgement and adjustment. Data are presented on initial psychometric analyses of the inventory. Analyses of the eight scales supported their homogeneity and relative independence, and the inventory's construct validity was partially documented. A moderately high degree of relationship was found between the Acknowledgement and Adjustment scales and the Acceptance of …

Interpolated Activity Effects In Distributed Practice, Ramond King Stout

Dissertations and Theses

The purposes of this study were to evaluate the effect of different rest interval activities in distributed practice (DP) upon the rate of learning a PA task, to evaluate the effectiveness of different rest interval activities in controlling rehearsal, and to investigate the role of rehearsal in DP performance.

Three experiments compared three different pairs of rest interval activities. One pair of activities, color naming (CN) and sequential addition (SA), was machine paced (MFA). A second pair, cartoon reading (CR) and symbol cancellation (SC), was self-paced (SPA). The third pair required no formal activity (NFA), Ss were instructed to rehearse …
