#1
Which sensory receptor is responsible for detecting light?
Photoreceptor
ExplanationPhotoreceptors detect and respond to light stimuli.
#2
Which of the following is NOT one of the five basic tastes?
Sweetness
ExplanationSweetness is not one of the five basic tastes, which include salty, sour, bitter, umami, and sometimes fatty.
#3
Which of the following is NOT a type of somatosensory receptor?
Olfactory receptor
ExplanationOlfactory receptors are not somatosensory receptors; they detect odors, while somatosensory receptors detect touch, temperature, and pain.
#4
The ability to perceive depth and distance accurately is known as:
Depth perception
ExplanationDepth perception is the ability to perceive the relative distance of objects accurately.
#5
Which part of the eye is responsible for regulating the amount of light that enters?
Pupil
ExplanationThe pupil, a hole in the center of the iris, regulates the amount of light that enters the eye.
#6
Which of the following is NOT considered a primary taste sensation?
Umami
ExplanationUmami, also known as savory, is considered one of the five primary taste sensations, along with salty, sour, bitter, and sweet.
#7
Which theory suggests that perception is the result of a bottom-up process where sensory information is analyzed and combined to form a percept?
Feature detection theory
ExplanationFeature detection theory proposes that sensory receptors respond to specific features or elements of a stimulus.
#8
Who proposed the opponent-process theory to explain color vision?
Ewald Hering
ExplanationEwald Hering proposed the opponent-process theory, which suggests that color vision is based on opposing pairs of color receptors.
#9
Which theory proposes that perception is influenced by both top-down processing and bottom-up processing?
Constructivist theory
ExplanationConstructivist theory suggests that perception is influenced by both top-down processing (expectations and prior experiences) and bottom-up processing (sensory information).
#10
What term refers to the smallest change in stimulation that can be detected 50% of the time?
Difference threshold
ExplanationDifference threshold, also known as just noticeable difference (JND), is the smallest change in stimulation that can be detected 50% of the time.
#11
The theory that suggests that sensory receptors respond to specific features or elements of a stimulus is known as:
Feature detection theory
ExplanationFeature detection theory suggests that sensory receptors respond to specific features or elements of a stimulus.
#12
Which part of the brain is primarily responsible for processing olfactory information?
Olfactory bulb
ExplanationThe olfactory bulb, located in the forebrain, is primarily responsible for processing olfactory information.
#13
The vestibular system contributes to which sensory perception?
Balance and spatial orientation
ExplanationThe vestibular system contributes to maintaining balance and spatial orientation.
#14
Who proposed the theory of pain modulation involving the 'gate control' mechanism?
Ronald Melzack and Patrick Wall
ExplanationRonald Melzack and Patrick Wall proposed the 'gate control' theory of pain modulation, which suggests that the spinal cord contains a neurological 'gate' that controls pain signals.
