Eyetracking and selective attention in category learning.
An eyetracking version of the classic Shepard, Hovland, and Jenkins (1961) experiment was conducted. Forty years of research has assumed that category learning often involves learning to selectively attend to only those stimulus dimensions useful for classification. We confirmed that participants learned to allocate their attention optimally. We also found that learners tend to fixate all stimu...

An eyetracking version of the classic Shepard, Hovland and Jenkins (1961) experiment was conducted. Forty years of research has assumed that category learning includes learning how to selectively attend to only those stimulus dimensions useful for classification. We confirmed that participants learned to allocate their attention optimally. We also found that learners tend to fixate all stimulus...
متن کاملRunning Head: Knowledge and Attention in Category Learning How Prior Knowledge Affects Selective Attention During Category Learning: An Eyetracking Study
Research has shown that category learning is affected by (a) attention, which selects which aspects of stimuli are available for further processing, and (b) the existing semantic knowledge that learners bring to the task. However, little is known about how knowledge affects what is attended. Using eyetracking, we found that (a) knowledge indeed changes what features are attended, with knowledge...
متن کاملKnowledge Effect and Selective Attention in Category Learning: An Eyetracking Study
Two experiments tested the effect of prior knowledge on attention allocation in category learning. Using eyetracking, we found that (a) knowledge affects dimensional attention allocation, with knowledge-relevant features being fixated more often than irrelevant ones, (b) this effect was not due to initial attention bias to the relevant dimensions but rather gradually emerged in response to obse...
متن کاملThirty-something categorization results explained: selective attention, eyetracking, and models of category learning.
An eyetracking study testing D. L. Medin and M. M. Schaffer's (1978) 5-4 category structure was conducted. Over 30 studies have shown that the exemplar-based generalized context model (GCM) usually provides a better quantitative account of 5-4 learning data as compared with the prototype model. However, J. D. Smith and J. P. Minda (2000) argued that the GCM is a psychologically implausible acco...
