Recently, nonparametric methods have been proposed that provide a dimensionally based description of test structure for tests with dichotomous items. Because such methods are based on different notions of dimensionality than are assumed when using a psychometric model, it remains unclear whether these procedures might lead to a different…

This study indicated that the dimensions of the configuration provided by INDSCAL multidimensional scaling are psychologically relevant to learning the concept of artistic style and that sensitivity to these dimensions, as measured by INDSCAL subject weights, can predict important individual differences in responses to another group of stimuli.…
