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...
متن کاملMemory Processes in Perceptual Decision Making
In a decision making task repeated encounters of a visual stimulus attribute to improved performance in identification and classification of that stimulus. This process is termed as repetition priming. Recent studies have proposed that response learning (RL), where previous decision gets associated with that item, accounts for a significant portion of performance gains observed in repetition pr...

متن کاملPerceptual 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...
متن کاملInfluence of Rationality and Perceptual Processes on Managerial Decision-Making
Managerial decision-making and rationality are impacted and influenced by perceptual processes. This essay seeks to critically analyse and discuss perceptual processes as pivotal in any decision-making endeavour. Its importance is briefly discussed with particular emphasis placed on ways in which certain differences or biases in perception may have on individuals’ understanding of reality as we...
