Altering object representations through category learning

Altering object representations through category learning.

Previous research has shown that objects that are grouped together in the same category become more similar to each other and that objects that are grouped in different categories become increasingly dissimilar, as measured by similarity ratings and psychophysical discriminations. These findings are consistent with two theories of the influence of concept learning on similarity. By a Strategic ...

We discuss several models of learning object representations...

Category Learning Through Active Sampling

Laboratory studies of human category learning tend to emphasize passive learning by limiting participants’ control over the information they experience on every trial. In contrast, we explore the impact that active data selection has on category learning. In our experiment, participants attempted to learn categories under either entirely passive conditions, or by actively selecting and querying...

How category learning affects object representations: not all morphspaces stretch alike.

How does learning to categorize objects affect how people visually perceive them? Behavioral, neurophysiological, and neuroimaging studies have tested the degree to which category learning influences object representations, with conflicting results. Some studies have found that objects become more visually discriminable along dimensions relevant to previously learned categories, while others ha...
