What condition does Oliver Sacks suffer from?

• Prosopagnosia

• Anosognosia

• Aphasia

• Agraphia

What is the primary difference between sensation and perception?

• Sensation involves external stimuli, while perception involves the brain's interpretation.

• Perception is only related to vision, while sensation involves all senses.

• Sensation can be controlled voluntarily, perception cannot.

• Perception occurs before sensation in the process of recognizing stimuli.

What does the Absolute Threshold of Sensation refer to?

• The maximum intensity of a stimulus one can perceive

• The minimum intensity of a stimulus required for detection 50% of the time

• The average intensity of stimuli detected during a given period

• The intensity of stimulus required for 100% detection rate

According to Signal Detection Theory, what can influence the detection of a weak stimulus?

• The stimulus' duration and frequency

• The stimulus' color and shape

• The person's psychological state and expectations

• The number of stimuli presented simultaneously

What is sensory adaptation?

• The improvement of sensory abilities over time

• The decrease in sensitivity to an unchanging stimulus

• The adaptation of sensory organs to different environments

• The brain's adaptation to sensory impairments

What does Weber's Law state about perception?

• Perception does not change with the stimulus' intensity

• Differences are perceived on a logarithmic scale

• Differences are perceived based on the stimulus' intensity

• Differences are perceived on a linear scale

How are light waves transformed into neural messages?

• By the cornea reflecting light directly to the optic nerve

• By the sclera absorbing light and converting it

• Through the lens focusing light onto the retina

• Through the pupil adjusting the intensity of light

What role do rods and cones play in vision?

• Rods detect color, while cones detect light intensity

• Rods and cones both detect fine detail and color

• Rods detect grayscale and peripheral vision, while cones detect detail and color

• Cones detect motion, while rods detect static images

What does the trichromatic theory of color vision propose?

• Color vision is an illusion created by the brain

• Humans can only see three colors: blue, green, and red

• Color vision depends solely on the intensity of light

• Color vision is based on three types of cones sensitive to blue, green, and red

What is parallel processing in the context of visual perception?

• The brain's method of processing colors one at a time

• The linear processing of visual information from the retina to the brain

• The brain's ability to process multiple stimuli in sequence

• The simultaneous processing of different aspects of a visual scene
