| Abstract: | According to mathematical models, neural noise operating on a within-trial timescale has a major impact on the timing and accuracy of our perceptual choices. However, the models themselves do not provide a means of estimating the noise levels of individual observers. Through a combination of psychophysics and neurophysiological recordings, the present study aims to identify reliable signatures of within-trial noise in EEG. This work can contribute to the development of novel ‘neurally-informed’ decision models that would be particularly beneficial in studies of individual differences or group comparisons. | ||
