Suppose you are participating in an experiment to see if people can detect very subtle emotional expressions on other people's faces.However, sometimes the image the experimenter shows you is blurry, and it is hard to distinguish whether or not you see an emotional expression.You decide that you will respond by indicating you have detected an emotion in a person's face, even when you are unsure.According to signal detection theory, which of the following two outcomes are you most likely to have?
A)hits and misses
B)misses and correct rejections
C)hits and false alarms
D)false alarms and correct rejections

Signal detection theory proposes that when making judgments in ambiguous situations, such as trying to detect emotional expressions from blurry images, people have a threshold for making a decision. When presented with an ambiguous image, a person can either detect the correct emotion (a hit), fail to detect the emotional expression (a miss), incorrectly report detecting an emotion when there is none (a false alarm), or correctly report not detecting an emotion (a correct rejection).

In the given scenario, the person has decided to respond by indicating they have detected an emotion in a person's face even when they are unsure. This means they are willing to make more false alarms (reporting emotions when there are none) than necessary. Therefore, the person is most likely to have hits and false alarms as their outcome.
