AP Psychology Unit 3: Sensation and Perception Quiz

What is the primary difference between sensation and perception?

• Sensation involves interpretation, while perception is raw data.

• Sensation is raw data from senses, while perception involves interpretation.

• Sensation and perception are the same processes.

• Perception is the process of receiving stimuli, while sensation interprets them.

Which type of processing requires prior knowledge and past experiences?

• Bottom-up processing

• Top-down processing

• Parallel processing

• Lateral processing

Which Gestalt principle involves perceiving objects in their simplest form?

• Symmetry

• Similarity

• Closure

• Figure and Ground

What does the Gestalt principle of closure refer to?

• Perceiving objects as a single unit

• Filling in missing information to complete an image

• Grouping similar objects together

• Following lines and curves instinctively

How do binocular cues contribute to depth perception?

• By using both eyes to perceive depth

• By relying on the size of objects

• By using one eye to perceive distance

• By focusing on the color of objects

What is the role of retinal disparity in depth perception?

• It enhances the brightness of objects.

• It provides depth by comparing different images from each eye.

• It allows for the perception of motion.

• It helps in perceiving color differences.

What is the absolute threshold in sensory processing?

• The average amount of stimulation needed to detect a stimulus

• The minimum amount of stimulation needed to detect a stimulus

• The maximum amount of stimulation needed to detect a stimulus

• The threshold at which all stimuli are detected

What does sensory adaptation refer to?

• Decreased sensitivity to a changing stimulus

• Decreased sensitivity to a constant stimulus

• Increased sensitivity to a changing stimulus

• Increased sensitivity to a constant stimulus

According to Weber-Fechner's Law, how must two stimuli differ for a difference to be noticed?

• By a variable amount

• By a constant amount

• By a constant percent

• By a variable percent

What is the difference threshold?

• The minimum change needed to detect a difference between two stimuli

• The average change needed to detect a difference between two stimuli

• The threshold at which no difference is detected

• The maximum change needed to detect a difference between two stimuli
