Individual differences in attention influence perceptual decision making

Sequential sampling decision-making models have been successful in accounting for reaction time (RT) and accuracy data in two-alternative forced choice tasks. These models have been used to describe the behavior of populations of participants, and explanatory structures have been proposed to account for between individual variability in model parameters. In this study we show that individual di...

Perceptual decision making from correlated samples

The optimal perceptual decision making strategy for weighting serially presented information depends on the degree of sample dependence. Uniform weighting produces optimal estimates from independent samples, but increases in autocorrelation should be matched by increasing and symmetric overweighting of early and late samples in order to maintain optimal performance. In the current experiment, p...

Perceptual expectation evokes category-selective cortical activity.

Selective visual attention directed to a location (even in the absence of a stimulus) increases activity in the corresponding regions of visual cortex and enhances the speed and accuracy of target perception. We further explored top-down influences on perceptual representations by manipulating observers' expectations about the category of an upcoming target. Observers viewed a display in which ...

Selective Attention Increases Choice Certainty in Human Decision Making

Choice certainty is a probabilistic estimate of past performance and expected outcome. In perceptual decisions the degree of confidence correlates closely with choice accuracy and reaction times, suggesting an intimate relationship to objective performance. Here we show that spatial and feature-based attention increase human subjects' certainty more than accuracy in visual motion discrimination...

Dissociating sensory from decision processes in human perceptual decision making

A key question within systems neuroscience is how the brain translates physical stimulation into a behavioral response: perceptual decision making. To answer this question, it is important to dissociate the neural activity underlying the encoding of sensory information from the activity underlying the subsequent temporal integration into a decision variable. Here, we adopted a decoding approach...
