Labeling experimental effects as "due to attention" merely
categorizes, it does not explain. Many cueing experiments demonstrating
attentional effects share the characteristic that cues change the
conditional probability of target locations or features. I will present
data showing that probability itself is an effective cue for
conjunctions of target position and features, a conjunction not easily
accounted for by models of spatial and feature attention. Along with
improving the speed and accuracy of performance, probability cues alter
the shape of error distributions so as to increase kurtosis (both the
peak and tails of the distributions increase). Changes in distribution
shapes may suggest a mechanism for how different stimulus frequencies
directly effect behavioral performance and yield "attentional effects"
without the need for special attentional mechanism.
