Abstract
Selectively attention to perceptual dimensions and switching between dimensions have been studied in two separate literatures. The present experiment examined both of these abilities.
Participants classified objects according to shape and brightness in single-task conditions and switched between these tasks in mixed tasks conditions, including trials in which the classification rule switched (switch) or repeated (repeat). Saturation, was either constant (base) or varied orthogonally (filtering). Filtering (vs. base) influenced brightness classification (showing Garner Interference, GI) but not shape classification. This GI was largest in single-task conditions and smallest in switch conditions. Thus, challenging filtering/switching ability did not compromise the other ability. Systems Factorial
Technology analyses of the brightness task show that, in most of the participants, switching cost (switch vs. repeat) and GI were related to serial exhaustive processes while mixing cost (repeat vs. single task) and GI were related to parallel exhaustive processes.
