Question 12

According to signal-detection theory, an observer's response in a detection task involves a sensory response and a decision response. Fill in the names of the responses that are possible in the table:
 $$\begin{array} { | l | l | l | } 
\hline & \text { Stimulus is present } & \text { Stimulus is absent } \
\hline \begin{array} { l } 
\text { Person responds by saying the } \
\text { stimulus is present }
\end{array} & & \
\hline \text { Person responds by saying the } & & \

Question 13

The centre of the retina contains a mixture of about 75% rods and 25% cones.

Accepted Answer

A) True 
 B)False

Question 14

Ordinarily we need to know not only what something is, but also where it is. Since vision doesn't give us this information directly, we must infer it. Explain how we perform this feat, giving examples of two visual cues that require the use of both eyes. The textbook notes that there are many visual cues that do not depend on having two eyes. Choose and describe five of the seven cues that depend upon one eye.
