Abstract
Five experiments are reported from which it is concluded
that attending on the basis of a stimulus feature (e.g., red) does
not directly affect the sensory quality of stimuli that possess that
feature. Feature-based attention was manipulated in a visual search
task by providing information about the probability that the target
would possess a given feature (e.g., "The target has a 1.0
probability of being red when present."). Feature-based attention
failed to aid performance under "data-limited" conditions (i.e., those under which performance was primarily affected by the quality
of the stimulus) but did affect performance under conditions that
were not data limited (Experiments 1-3). If attending to a
feature had affected the sensory quality of stimuli, performance
should have been aided under all conditions. Experiments 4 and 5
provided converging support for this conclusion.
