The Versatility of SpAM: A Fast, Efficient, Spatial Method of Data Collection for Multidimensional Scaling
Peer reviewed Peer reviewed
Direct linkDirect link
Hout, Michael C.; Goldinger, Stephen D.; Ferguson, Ryan W. – Journal of Experimental Psychology: General, 2013
Although traditional methods to collect similarity data (for multidimensional scaling [MDS]) are robust, they share a key shortcoming. Specifically, the possible pairwise comparisons in any set of objects grow rapidly as a function of set size. This leads to lengthy experimental protocols, or procedures that involve scaling stimulus subsets. We…

A Multidimensional Scaling Analysis of Own- and Cross-Race Face Spaces
Peer reviewed Peer reviewed
Direct linkDirect link
Papesh, Megan H.; Goldinger, Stephen D. – Cognition, 2010
We examined predictions derived from Valentine's (1991) Multidimensional Space (MDS) framework for own- and other-race face processing. A set of 20 computerized faces was generated from a single prototype. Each face was saved as Black and White, changing only skin tone, such that structurally identical faces were represented in both race…

Forster, Natalie; Souvignier, Elmar – Learning Disabilities: A Contemporary Journal, 2011
The purpose of this study was to examine the technical adequacy of a computer-based assessment instrument which is based on hierarchical models of text comprehension for monitoring student reading progress following the Curriculum-Based Measurement (CBM) approach. At intervals of two weeks, 120 third-grade students finished eight CBM tests. To…

Factorial Validity and Invariance Testing of the Exercise Dependence Scale-Revised in Swedish and Portuguese Exercisers
Peer reviewed Peer reviewed
Direct linkDirect link
Lindwall, Magnus; Palmeira, Antonio – Measurement in Physical Education and Exercise Science, 2009
The present study investigated the factorial validity and factorial invariance of the 21-item Exercise Dependence Scale-Revised using 162 Swedish and 269 Portuguese exercisers. In addition, the prevalence of exercise dependence symptoms and links to exercise behavior, gender, and age in the two samples was also studied. Confirmatory factor…

Performance Modeling That Integrates Latent Trait and Class Theory.
Peer reviewed Peer reviewed
Gitomer, Drew H.; Yamamoto, Kentaro – Journal of Educational Measurement, 1991
A model integrating latent trait and latent class theories in characterizing individual performance on the basis of qualitative understanding is presented. This HYBRID model is illustrated through experiments with 119 Air Force technicians taking a paper-and-pencil test and 136 Air Force technicians taking a computerized test. (SLD)

Multidimensional Equating.
Peer reviewed Peer reviewed
Hirsch, Thomas M. – Journal of Educational Measurement, 1989
Equatings were performed on both simulated and real data sets using common-examinee design and two abilities for each examinee. Results indicate that effective equating, as measured by comparability of true scores, is possible with the techniques used in this study. However, the stability of the ability estimates proved unsatisfactory. (TJH)
