Visual Object Representations
Description
Contains two similarity matrices related to an experiment on visual object represenations.
similarities (correlations) of 54 OCP (see O'Reilly, Chatman, and Caldwell, 1991) items. The last three columns contain the facet assigned by Bilsky and Jehn (2002) as well as the external variables for regional restrictions.
Usage
data(VaziriXu)Format
List of two similarity matrices from two experimental conditions: artificial and real object categories.
V1-V4: early visual areas
LO: lateral occipital regions
VOT: ventral occipitotemporal regions
V3A, V3B, IPS0-IPS4: topographic regions along the intraparietal sulcus
Inferior IPS: inferior intraparietal sulcus
Superior IPS: superior intraparietal sulcus
