The hierarchical model of van der Linden is the most popular model for responses and response times in tests. It is composed of two separate submodels--one for the responses and one for the response times--that are joined at a higher level. The submodel for the response times is based on the lognormal distribution. The lognormal distribution is a…

This study examined the association between female sexual offending behavioral patterns, as delineated by Sandler and Freeman's (2007) typologies, and executive functioning. The sample included all referrals for sexual offender assessments within a women's maximum/medium security prison between January 2009 and October 2009. Each subject was…

The intercorrelation matrix of the ITPA subtests drawn from a population of disadvantaged children as presented by Cicirelli, et al. was analyzed by the Guttman-Lingoes SSA-I Program. The results supported two dimensions in the theoretical model suggested by the ITPA developers, the communication channel and the process level. (Author)

This is one of a series of reports on the National Longitudinal Study of Mathematical Abilities (NLSMA). This report describes the processes used for deciding what should be measured, when, and how. Work of the SMSG Panel on Tests for collecting tests items, conceptualizing scales, pilot testing, and analyzing pilot test data is reviewed. The…

This is one of a series of reports on the National Longitudinal Study of Mathematical Abilities (NLSMA). This report examines measures of attitude, self-concept, and anxiety as outcomes of mathematics instruction for students in grades 4-12. (NLSMA Reports Nos. 1-7 and 9 provide background information on the measures and the population.) Specific…
