Multidimensional scaling models of stimulus domains are widely used as a representational basis for cognitive modeling. These representations associate stimuli with points in a coordinate space that has some predetermined number of dimensions. Although the choice of dimensionality can significantly

β¦ Synopsis
Based on evidence presented for the Need for Cognition Scale in its original and abbreviated versions, users of the instrument assume its unidimensionality. In three exploratory studies, maximum-likelihood factor analysis reveals the presence of multiple dimensions in both forms of the scale. Four dimensions-enjoyment of cognitive stimulation, preference for complexity, commitment of cognitive effort, and desire for understanding-emerged with some consistency across samples and were found to be fairly resistant to changes in the polarity of scale items and to explain differentially consumer response to advertisements.
