Free General Psychology MCQs with Answers

• A. prosopagnia
• B. achromatospia
• C. dyslexia
• D. glaucoma

Explanation: Glaucoma develops when increased fluid pressure inside the eye damages the optic nerve and may progressively impair vision.

• A. lens
• B. iris
• C. pupil
• D. cornea

Explanation: The iris is the pigmented, colored ring surrounding the pupil and controls how much light enters the eye.

• A. photons
• B. waves
• C. intensity
• D. photoreception

Explanation: Light can be described in terms of photons, waves, and intensity. Photoreception is the process of detecting light with receptor cells…

• A. stimulus thresholds
• B. sensory transduction
• C. the tricolor theory
• D. reinforcement rate matching

Explanation: Weber’s law states that the just-noticeable difference is a constant proportion of the original stimulus, making it a law about sensory…

• A. rods
• B. bipolar cells
• C. cones
• D. ganglion cells

Explanation: Cones are retinal receptor cells specialized for color vision and detailed vision in relatively bright light.

• A. shape constancy
• B. size constancy
• C. motion parallax
• D. interposition

Explanation: The Ames room creates a misleading perspective in which equal-sized people appear different in size, testing how visual context can…

• A. auditory
• B. kinesthetic
• C. olfactory
• D. vestibular

Explanation: The semicircular canals detect rotational movements of the head and contribute to balance, making them part of the vestibular sense.

• A. closure
• B. figure and ground
• C. proximity
• D. distance

Explanation: Figure-ground organization separates an object of focus, the figure, from its surrounding background, the ground.

• A. anvil
• B. ear canal
• C. basilar membrane
• D. ear drum

Explanation: The basilar membrane is a key structure inside the cochlea: its movement stimulates hair cells that convert sound vibrations into neural…

• A. the duplicity theory
• B. Wever's volley principle
• C. Hering's opponent process theory
• D. Helmholtz's trichromatic theory

Explanation: A red stimulus producing a green afterimage reflects opponent color processes, in which red and green operate as opposing pairs.

• A. vestibular system
• B. pinna
• C. round window
• D. cochlea

Explanation: The cochlea contains the basilar membrane and hair cells that convert sound vibrations transmitted through the inner ear into nerve…

• A. texture-density gradient
• B. retinal disparity
• C. reciprocal innervations
• D. retinal polarity

Explanation: A texture-density gradient is a monocular cue: surfaces appear denser and finer with increasing distance.

• A. provide a sense of balance
• B. provide the ability to taste
• C. provide a sense of touch
• D. provide an ability to feel an emotion

Explanation: The vestibular organs detect head movement and orientation relative to gravity, providing information needed for balance and bodily…

• A. texture
• B. light and shadow
• C. convergence
• D. linear perspective

Explanation: Convergence is a physiological, binocular cue because the eyes turn inward for nearby objects.

• A. cochlea
• B. ossicles
• C. round window
• D. Organ of Corti

Explanation: The middle ear occupies the space between the eardrum and oval window and contains the three ossicles: malleus, incus, and stapes.

• A. outer ear
• B. oval window
• C. cochlea
• D. ossicles

Explanation: The pinna, or auricle, is the visible flap that collects sound and directs it into the ear canal, so it belongs to the outer ear.

• A. formation of neural impulse
• B. sound-wave amplification
• C. sound collection
• D. transmission to the brain

Explanation: The middle ear, especially the ossicles, amplifies and mechanically transfers vibrations from the eardrum to the inner ear.

• A. apparent motion
• B. induced motion
• C. the autokinetic effect
• D. binocular disparity

Explanation: The autokinetic effect is the illusory movement of a stationary light seen in an otherwise dark environment.

• A. deoxyribonucleic acid
• B. genes
• C. atoms
• D. myelin

Explanation: Chromosomes are made mainly of DNA wound around protein molecules; DNA stores the genetic instructions.

• A. a disease of the blood cells
• B. hyperventilation
• C. interruption of the oxygen supply to brain
• D. an oversupply of oxygen to the brain

Explanation: Anoxia means a severe interruption or absence of oxygen supply, especially to the brain, and it can cause serious neurological damage.
