This self-report study investigated 274 pre-service teachers' attitudes toward students with learning and behavioural difficulties (LBD) and the factors that predict their attitudes. Using four scenarios describing students with LBD, we investigated the degree to which pre-service teachers' open-minded thinking dispositions, readiness to learn…

This study aims to extensively examine the psychometric properties of adapted version of the Satisfaction with Life Scale (SWLS) in different Turkish samples. In order to test the psychometric properties of the SWLS three separate and independent samples are utilized in this study, namely university students (n = 547), correctional officers (n =…

Age-normed tests of listening comprehension, oral expression, reading comprehension, and written expression were administered in Grades 1 (n = 128), 3, and 5, or 3 (n = 113), 5, and 7. Confirmatory factor analyses compared 1- and 4-factor models at each grade level and supported a 4-factor model of language by ear, mouth, eye, and hand. Multiple…

The responses of 472 educators were used to develop the Pre-Referral Intervention Team Inventory (PRITI), a 24-item Likert scale. Principal axis analyses resulted in a one-dimensional structure with high internal consistency that explained 57% of the total variance. Acceptability of team procedures was strongly and positively correlated with a…

The Rasch model of latent trait test theory is extended to multiple choice questionnaires. The statistical development and logic of the extension is presented and implications of the extension are discussed. (JKS)

It is shown that, under very general conditions, uniqueness estimates proposed independently by Guttman (1957) and by Harris (1963) provide tighter upper bounds on the unknown uniqueness values of factor analysis than do existing estimates. (Editor)

This paper made an important distinction between determinacy of common-factors and determinacy of unique-factors and examined the implications of two results previously obtained by Guttman. (Author/RK)

Recent attempts have been made to find a robust method for comparing the variances of "J" dependent random variables. However, these procedures can give unsatisfactory results. Several new procedures that are derived heuristically are examined. The most effective method is based on the statistic derived by D. Quade. (TJH)

Discusses the dynamic assessment of information-processing ability by detailing development, standardization, and preliminary validation of Cognitive Processing Test (S-CPT). Presents information pertaining to development and standardization of psychometric properties. Discusses problems and advantages of measures. (Author/JDM)

Describes the life and work of Gustav Fechner, whose drive to model the world left a heritage of measurement used daily. His efforts to link body and mind, or stimulus and sensation, led to his proposal that a geometric series in the intensity of a stimulus might correspond to an arithmetic series in the sensation. (SLD)

Discusses the career of Louis Thurstone, who parented modern psychometrics. His scaling methods conceptualized mental forces as abstract linear continua, objectively measured on numerical scales with their interrelations expressed as mathematical formulations. (SLD)

Presents three lines of evidence that fail to support R. Sternberg's theory of general intelligence ("g"): (1) animal problem solving studies; (2) studies of children with attention-deficit hyperactivity disorder; and (3) studies of patients with frontal lobe damage. Discusses differences between psychometric "g" and practical…
