• A. Pitch
• B. Timbre
• C. Amplitude
• D. Frequency

Explanation: Amplitude is the height or intensity of a sound wave, so it determines perceived loudness or strength.

• A. Look at the moon during a lunar eclipse
• B. Think you see the moon when in fact it is not there
• C. Perceive the moon to be the same size when viewed on the horizon and overhead
• D. Perceive the moon to be larger on the horizon than overhead

Explanation: The moon illusion is the tendency to perceive the full moon as larger near the horizon than when it is high overhead.

• A. Constancy
• B. Similarity
• C. Closure
• D. Proximity

Explanation: The principle of similarity groups objects that share features such as colour, so Babar sees the green-jacketed spectators as one group.

• A. Selective attention and lightness constancy
• B. Perceived distance and perceived size
• C. Proximity and closure
• D. Atmospheric air pressure and diffusion of light waves

Explanation: The moon seems larger on the horizon because surrounding distance cues make it appear farther away, and the brain compensates by…

• A. Visual capture
• B. Relative motion
• C. Retinal disparity
• D. The phi phenomenon

Explanation: The phi phenomenon is the apparent movement produced when stationary lights flash in sequence, as in moving or pulsating signs.

• A. An environmental depth cue in which closer objects overlap objects farther away
• B. The relationship between bipolar and ganglion cells
• C. The depth cue that uses the angle of the light to determine distance
• D. The lens ability to change shape and focus light directly on the retina

Explanation: Interposition, or occlusion, is a monocular depth cue in which a nearer object blocks part of a farther object.

• A. Context effects
• B. Relative clarity
• C. Perceptual adaptation
• D. Visual capture

Explanation: Removing distance cues with a narrow tube changes the surrounding visual context and reduces the horizon moon illusion.

• A. Texture gradient
• B. Convergence
• C. Light and shadow
• D. Interposition

Explanation: Texture gradient refers to the gradual change from clearly visible, coarse texture nearby to finer, less distinct texture farther away.

• A. Retinal disparity
• B. The phi phenomenon
• C. Visual capture
• D. Location constancy

Explanation: Visual capture occurs when strong visual motion dominates other sensory information, making a stationary observer feel as if they are…

• A. Smell
• B. Hearing
• C. Kinesthesis
• D. Vision

Explanation: Vision usually dominates when sensory information conflicts, an effect called visual capture.

• A. Linear perspective
• B. Relative size
• C. Interposition
• D. Accommodation

Explanation: Relative size is a monocular depth cue: when two familiar objects are known to be equal in size, the one forming the smaller retinal image…

• A. Clouds in the sky
• B. Fish in the sea
• C. Rungs in ladder
• D. Words in a sentence

Explanation: The principle of connectedness makes elements joined by a continuous visual connection seem to form one unit.

• A. Motion parallax
• B. Texture gradient
• C. Height in plane
• D. Linear perspective

Explanation: Linear perspective creates depth because parallel lines appear to converge as they extend into the distance.

• A. Stroboscopic movement
• B. Visual capture
• C. The Ponzo illusion
• D. Perceptual adaptation

Explanation: Stroboscopic movement is the apparent motion produced when still images are shown rapidly in sequence, as in a film.

• A. Gestalt
• B. Perceptual constancy
• C. Schema
• D. Perceptual adaptation

Explanation: A schema is an organized knowledge framework that helps interpret incomplete or ambiguous sensory input.

• A. Sensory interaction
• B. Retinal interaction
• C. Perceptual constancy
• D. Depth perception

Explanation: Depth perception is the process of converting two-dimensional retinal images into an experience of a three-dimensional world.

• A. The phi phenomenon
• B. Perceptual constancy
• C. Interposition
• D. Selective attention

Explanation: Selective attention allows a person to focus on a chosen stimulus while filtering out competing sounds.

• A. Perceptual schemas
• B. Relative clarity
• C. Shape constancy
• D. Stroboscopic movement

Explanation: Perceptual schemas are mental templates that guide interpretation of unclear patterns, causing people to detect familiar forms such as…

• A. Perceptual adaptation
• B. Relative clarity
• C. Change blindness
• D. The cocktail party effect

Explanation: The cocktail party effect is the ability to attend selectively to one auditory source while filtering competing sounds. Mrs.

• A. Grouping of stimuli into smooth, uninterrupted patterns
• B. Perception of an object as unchanging in shape regardless of our own viewing angle
• C. Tendency for novel or unfamiliar stimuli to capture our attention
• D. Perceptual adjustment to an artificially displaced visual field

Explanation: Perceptual adaptation is the adjustment of perception to altered sensory input, such as a visual field shifted by special glasses or…
