    "title": "Effect of a colour-based descriptor and stimuli presentation mode in unsupervisedcategorization",
    "subtitle": null,
    "abstract": "In unsupervised categorization, studies have shown that fewer stimuli dimensions are used for categorization with serialpresentation compared to concurrent presentation of stimuli. In this study, we investigate how a colour-based multidimen-sional descriptor might affect the number of dimensions used in categorization. Our results show that a fewer numberof dimensions are used when stimuli are presented serially irrespective of the presence of a colour-based descriptor. Wefound main effects for both the stimuli presentation mode and the colour-based descriptor. The stimuli has the same logicalstructure across all the conditions. Our results show that the notion of a natural and intuitive grouping of items is affectedby meta-level feature descriptors, that are not part of a feature-based representation of stimuli. We discuss the implica-tions of our findings for computational models of categorization, which make predictions based solely on feature-basedrepresentation of stimuli.",
