Document Summary
Present a stimulus half the time and not half the time. Looking at diference between the correct-incorrect responses to tell signal sensitivity: conservative inclined to say no, liberal inclined to say yes, or neutral - give reward for both correct and incorrect responses. If you set your rule low (perceived intensity 10) you"ll be over sensitive and. Perceived intensity 20 (and above) above 20 will be hits, anything below the rule (below 20) will be misses. Diiculty distinguishing noise vs. signal+noise there"s more overlap lots of misses, lots of false alarms (bc they"re similar to each other sound of the house and sound of the burglar) Little diiculty distinguishing little overlap, not as many false alarms or misses (bc they"re not as similar) Sensitivity is distinguished between noise alone and signal+noise: distance b/w two peaks large = more sensitivity, distance b/w two peaks small = less sensitivity.
