Perception Study

Uses tiny electrodes (wires) to measure the electrical activity of individual neurons. Single-cell recording
A method of determining a threshold in which the participant adjusts the stimulus for themselves to determine the point at which the threshold is crossed Method of adjustment
A method of determining a threshold in which a predetermined set of stimulus values are presented for many trials in random order. Method of constant stimuli
An error in threshold experiments in which the person tends to provide a different response (present or absent) from the one they gave on the last few trials. Errors of anticipation
Combining VEP's over many trials as a way to clarify the neural response to a specific stimulus by eliminating the random noise present on individual trials. Signal averaging
An approach to studying an observer's actual sensitivity to a stimulus independently of the factors that determine their response criterion. Signal detection theory
Using chemicals or electricity to temporarily increase the activity of specific brain areas to investigate the functioning of those areas. Microstimulation
Describes a situation in which an observer correctly responds "yes" when a stimulus is present. hit
