Symposium Overview
Some object characteristics can be perceived through both vision and touch. However, this does not imply that visual and tactual information is equivalent. In some cases, the information perceived by the two senses may conflict.

This symposium brings together a number of researchers that present behavioral studies of how people perceive and evaluate objects through vision and touch. Some studies focus on the comparison of visual and tactual sensory input, whereas others focus on the integration of these inputs.

Questions addressed include: How do people react to visual-tactual incongruities? How do people resolve the incongruities, to form a coherent percept? To what extent does the current percept depend on information presented previously and how is it updated?

The various, complimentary approaches presented in this symposium provide us with a rich understanding of how vision and touch work together in gathering information about the objects that surround people.
