Recent studies have revealed a relation between the given response and the response latency for personality questionnaire items in the form of an inverted-U effect, which has been interpreted in light of schema-driven behavior. In general, more probable responses are given faster. In the present study, the relationship between the probability of the given response and the response latency was i...

Item response theory (IRT) models are factor for dichotomous or polytomous variables (i.e., item responses). The symmetric logistic probit link functions most frequently utilized modeling items. In this article, we propose an IRT model and items using the asymmetric generalistic function that covers a lot of functions. Compared to based on function, generalized additionally estimates two parame...

Melodic discrimination tests have been used for many years to assess individual differences in musical abilities. These tests are usually analysed using classical test theory. However, classical test theory is not well-suited for optimising test efficiency or for investigating construct validity. This paper addresses this problem by applying modern item response modelling techniques to three me...

The purpose of the study was to determine comparability of an online version to the original paper-pencil version of Defining Issues Test 2 (DIT2). This study employed methods from both Classical Test Theory (CTT) and Item Response Theory (IRT). Findings from CTT analyses supported the reliability and discriminant validity of both versions. Findings from IRT analyses confirmed that both version...

IRT-based models with a general ability and several specific ability dimensions are useful. Studies have looked at item response models where the general and specific ability dimensions form a hierarchical structure. It is also possible that the general and specific abilities directly underlie all test items. A multidimensional IRT model with such an additive structure is proposed under the Bay...
