Data from: Pupil-linked arousal determines variability in perceptual decision making
Decision making between several alternatives is thought to involve the gradual accumulation of evidence in favor of each available choice. This process is profoundly variable even for nominally identical stimuli, yet the neuro-cognitive substrates that determine the magnitude of this variability are poorly understood. Here, we demonstrate that arousal state is a powerful determinant of variability in perceptual decision making. We measured pupil size, a highly sensitive index of arousal, while human subjects performed a motion-discrimination task, and decomposed task behavior into latent decision making parameters using an established computational model of the decision process. In direct contrast to previous theoretical accounts specifying a role for arousal in several discrete aspects of decision making, we found that pupil diameter was uniquely related to a model parameter representing variability in the rate of decision evidence accumulation: Periods of increased pupil size, reflecting heightened arousal, were characterized by greater variability in accumulation rate. Pupil diameter also correlated trial-by-trial with specific patterns of behavior that collectively are diagnostic of changing accumulation rate variability, and explained substantial individual differences in this computational quantity. These findings provide a uniquely clear account of how arousal state impacts decision making, and may point to a relationship between pupil-linked neuromodulation and behavioral variability. They also pave the way for future studies aimed at augmenting the precision with which people make decisions.
Research data supporting: Decreasing alertness modulates perceptual decision-making
<p>The zip file contains research data supporting the paper: Decreasing alertness modulates perceptual decision-making<br> The files are arranged in the following manner:</p> <ol> <li>The raw data is present for 32 subjects used in the analysis.<br> Each subject has a directory, for e.g. s_02 <br> a) Inside this directory, there are two directories:<br> awake: s_02_awake<br> drowsy: s_02_drowsy<br> b) The awake file has 124 trials, and the drowsy has 740 trials<br> c) The files are .mff format (egi) and the coding is as follows:<br> 'tone' - stimulus, 'RESP' - response. <br> Each 'tone' is followed by a 'DIN2' marker, that marks when the stimulus was actually presented.</li> <li> 'summary_Righthanders.csv' contains the other details for all subjects, with subject id and whether the data was<br> actually used for the analysis or not.</li> </ol>

Data from: Evidence accumulation and choice maintenance are dissociated in human perceptual decision making
Perceptual decision making in monkeys relies on decision neurons, which accumulate evidence and maintain choices until a response is given. In humans, several brain regions have been proposed to accumulate evidence, but it is unknown if these regions also maintain choices. To test if accumulator regions in humans also maintain decisions we compared delayed and self-paced responses during a face/house discrimination decision making task. Computational modeling and fMRI results revealed dissociated processes of evidence accumulation and decision maintenance, with potential accumulator activations found in the dorsomedial prefrontal cortex, right inferior frontal gyrus and bilateral insula. Potential maintenance activation spanned the frontal pole, temporal gyri, precuneus and the lateral occipital and frontal orbital cortices. Results of a quantitative reverse inference meta-analysis performed to differentiate the functions associated with the identified regions did not narrow down potential accumulation regions, but suggested that response-maintenance might rely on a verbalization of the response.
