What are the criteria proposed by Gibson (1969) for selecting an array of features for uppercase letters?

The features should change under different lighting conditions

The features should yield a unique pattern for each letter (correct)

The features should be randomly chosen to provide diversity

The features should not be critical

According to Hubel and Wiesel (1962, 1963), what kind of stimuli do cells respond to?

Stimuli that change frequently

Random stimuli with no specific patterns

Only certain kinds of stimuli, such as lines of a certain width and orientation (correct)

All kinds of stimuli equally

What is perceptual confusion in pattern recognition?

The frequency with which two patterns are mistakenly identified as each other (correct)

The difficulty in identifying familiar patterns

The ability to distinguish between similar patterns
