Document Summary
Most trials will have activity in the middle of the axis of the ndc called. Tone was sometimes given and sometimes not. Participants asked to report if they heard the tone. Monitoring the activation of auditory system to make a decision. There is a dimension of activity in the auditory system beta. Result is d prime: an objective measurement of the distance between the two distributions of the stimulus. Small d prime: not strong enough stimulus to detect. Large d prime: very strong stimulus detection. D prime is not going to change regardless of where you put beta. Hypothetical representations of the signal and noise probabilities distributed within a decision-maker. (a) response matrix of all signal-response combinations that can be made in a binary decision task. Green indicates correct decision, red indicates incorrect decision. (b) Proportions of hits and misses represented under the signal distribution.
