Exam 1: Foundations

In a signal detection experiment,participants are asked to respond when they detect a very low in- tensity tone.Fred responds to the tone on 80% of its presentations and Miguel responds to it 50% of the time.How could you determine whether Fred is more sensitive to the tone than is Miguel?

Question 1

Correct Answer:

Verified

At first glance,Fred may seem more sensitive,but he may also have a higher percentage of false-positive responses,suggesting a liberal decision-making bias,rather than greater sensitiv- ity.To make a comparison of their levels of sensitivity,one could plot each observer's rate of hits and false positives on an ROC plot;the more sensitive observer would be plotted closer to the upper left of the graph (indicating a higher d`. )
