The Structure of Working Memory: A Review and New View of Psychometric Models
… the 1970s, a great deal of research in cognitive psychology, developmental psychology, psychometrics, and cognitive neuroscience has investigated the structure and function of working memory (WM), defined as the ability to actively maintain and manipulate information in the service of complex …

An Empirical Investigation of Several Critical Psychometrical Issues in Neuropsychological Testing of Mild Traumatic Brain Injuries
Concussions can cause very serious injuries and with repetitive injuries increase the likelihood of serious consequences. There is an increased awareness of concussions, which has evolved into developing better measurement tools to study the effects including neuropsychological components. …

Development and Validation of an Instrument to Measure Student Attitude Toward Physical Education: A Mixed-Method Approach
The purpose of this study was to develop an instrument to assess middle school students' attitude toward physical education, to provide psychometric evidence of validity and reliability of the instrument, and to demonstrate further evidence of construct validity of the attitude instrument employing …

Properties of a Resampling Validation Technique for Empirically Scoring Psychological Assessments
"Four studies were conducted to examine the psychometric properties of a new, resampling-based validity estimator which does not require a crossvalidation sample in order to produce unbiased estimates of validity. The first and second experiments were Monte Carlo simulations while the third and …

SHARE: A Stochastic, Hierarchical Architecture for Reading Eye -Movement
The SHARE architecture is shown to be flexible enough to characterize both beginning and fluent reading, which is particularly attractive for the study of reading development. Its ability to capture eye-movement patterns also opens a wide range of possibilities for real-world applications of the …

A Comparison of Methods for Seriation and Unidimensional Scaling of Asymmetric Proximity Data
… and seriation of objects have a long history in psychology, anthropology, and statistics. Data in the form of asymmetric proximity matrices occur when we have observations from paired comparisons, round-robin tournaments, and networks. Skew-symmetric matrices are obtained by taking the …

Improving the Accuracy of Item Response Theory Parameter Estimates Through Simultaneous Estimation and Incorporation of Ancillary Variables
Finally, several practical considerations are also discussed. The most notable is the appropriateness of including ancillary information in reporting ability estimates. To address sufficiently the concerns and reservations surrounding this issue, theoretical underpinnings should be further …

Local Optima in K-Means Clustering
"The study of the properties of local optimality in K-means clustering is pursued. In doing so, it is shown that several of the commercial software packages prove to be inadequate in their treatment of the K-means algorithm, resulting in the proposal of an alternative method based on several …

Ordered Category Attribute Coding Framework for Cognitive Assessments
Cognitive Diagnostic Assessment models define skills as binary. Examinees are described as either 'skill masters' or 'non-masters' and items as either requiring the skill or not. I propose an Ordered Category Attribute Coding (OCAC) framework, designed to enhance the diagnostic information provided …

Generalized Linear Mixed Proficiency Models for Cognitive Diagnosis
Models for cognitive diagnosis combine discrete latent trait models with constrained latent class analysis, allowing the user to diagnosis the set of abilities an examinee may possess. Following a review of relevant cognitive diagnosis models and commonly used methods of estimation, implementation …

The Structural Representation of Three -Way Proximity Data
Scaling and clustering techniques are well-established statistical methods for generating continuous and discrete structural representations of the relationships between the row and column objects of proximity matrices. Most commonly, the representational structure is fit to the observed data …

Regression Models for Paired Comparisons
… the most widely used experimental methods in psychology and related fields. First employed in the middle of the 19th Century, many models have been developed over the years to analyze data from such experiments, for instance the Thurstone and Bradley-Terry-Luce models. This dissertation …

Computerized Adaptive Testing---New Developments and Applications
Computerized adaptive testing (CAT) has become a very important testing mode since it was introduced into the testing field in the early 1970's. It has clear advantages over the traditional paper-pencil testing in many aspects including shorter tests and more efficient score reporting. However, it …

An Item Response Unfolding Model for Graphic Rating Scales
… scale, a measurement tool used in many areas of psychology, usually takes a form of a fixed-length line segment, with both ends bounded and labeled as extreme responses. The raters mark somewhere on the line, and the length of the line segment from one endpoint to the mark is taken as the …

Identifying Untraited Individuals Using Model-Based Measurement
Results are used to motivate further research into the development and fine-tuning of models of untraited item responding. Implications of untraitedness are also discussed in the context of personality testing in organizational settings.

"An Investigation of Decomposed and Holistic Judgments in Multiattribute Decision Making: Generalizing the ""Divide and Conquer"" Principle"
Data is reported that compared the convergent validity (e.g. the agreement between decomposed and holistic strategies), the temporal stability and the external validity (the agreement between a decision strategy and an objective criterion) for decomposed and holistic judgments from two popular …

The Measurement of Valuing Diversity: Construction and Use of a New Scale for Work Groups
"The present research was conducted to build a new scale measuring the behavioral constructs of ""valuing diversity"" and to examine the antecedents and resulting outcomes of these behaviors in a team context by testing a conceptual model of work group diversity. The new scale, called Teamwork: …
