title: Whenis category learning holistic?
abstract: Ward and Scott (1987) recently provided evidence consistent with the idea that category learning can occur analytically whether that learning takes place under intentional or incidental conditions and whether the learner is an adult or a young child. Kemler Nelson (1988) raised concerns about Ward and Scott's conclusions as well as about the logic of some of their arguments. Kemler Nelson also attempted to strengthen the argument that incidental learning conditions induce a less strategic approach to tasks, which necessarily results in a holistic mode of processing. The present paper answers Kemler Nelson's concerns. It also presents arguments in favor of the idea that incidental learning is neither necessarily holistic nor necessarily analytic. It is argued that tasks, whether intentional or incidental, encourage the participant to process particular types of information. If the task encourages or demands the processing of separate features, then that type of information will be stored whether or not the participant was explicitly asked to learn the category membership of presented items. There are varieties of both intentional and incidental category learning, and what the learner does with the presented material is more important than his/her intent to learn. Furthermore, it is argued that the apparently discrepant results discussed by Kemler Nelson and Ward and Scott are all interpretable as specific cases within a more general episodic trace model of processing.
