Sensation Practice Test

Background noise is reduced, making the signal easier to distinguish from noise, increasing hits while decreasing false alarms due to higher sensitivity.

A participant expects the signal and guesses “yes” more often, increasing false alarms because expectations change perception into sensation.

A participant becomes paid for “yes” responses and reports more signals, increasing both hits and false alarms due to a liberal criterion shift.

A participant learns Weber’s law and then detects smaller proportional changes, causing a lower absolute threshold by definition.
