Perception Study
Question | Answer |
---|---|
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 |
