  • A. The cocktail party effect
  • B. Perceptual set
  • C. Relative clarity
  • D. The Ponzo illusion

Explanation: A perceptual set is a readiness to interpret sensory information in line with expectations or beliefs, so the rumors led Alyosha to…

Correct answer: Perceptual set
  • A. Context effects
  • B. Perceptual adaptation
  • C. Proximity
  • D. Visual capture

Explanation: Context effects occur when the surrounding setting influences recognition, so seeing the professor outside the familiar classroom context…

Correct answer: Context effects
  • A. Linear perspective
  • B. Convergence
  • C. Interposition
  • D. Retinal disparity

Explanation: A 3D film presents slightly different images to the two eyes, reproducing retinal disparity, the binocular depth cue produced by the brain…

Correct answer: Retinal disparity
  • A. Retinal disparity
  • B. Visual capture
  • C. Perceptual constancy
  • D. Top-down processing

Explanation: Knowing that an image can reverse directs attention and expectations, allowing prior knowledge to influence interpretation through…

Correct answer: Top-down processing
  • A. 20
  • B. 2
  • C. 10
  • D. 100

Explanation: A 20-decibel increase represents a 100-fold increase in sound intensity because each 10-decibel increase multiplies intensity by 10.

Correct answer: 100
  • A. Constancy
  • B. Simultaneous contrasts
  • C. Perceptual inference
  • D. Reversible figures

Explanation: These figures can be seen in two stable ways, such as a rat or professor, and a young or old woman, so they are reversible figures.

Correct answer: Reversible figures
  • A. Illuminate the entire retina
  • B. Facilitate the process of accommodation
  • C. Increase the input of light into the eye
  • D. Minimize sensory adaptation

Explanation: Tiny, continual eye movements shift the image across fresh retinal receptors, preventing the visual system from adapting completely to an…

Correct answer: Minimize sensory adaptation
  • A. Tinnitus
  • B. Accommodation
  • C. Blindsight
  • D. Priming

Explanation: A briefly presented and masked stimulus can influence responses without reaching conscious awareness, which is studied as masked priming.

Correct answer: Priming
  • A. Synesthesia
  • B. Signal detection
  • C. Sensation
  • D. Accommodation

Explanation: Sensation is the detection and initial encoding of physical stimulus energy by sensory receptors and the nervous system.

Correct answer: Sensation
  • A. Synesthesia
  • B. Blindsight
  • C. Subliminal perception
  • D. The McGurk effect

Explanation: Blindsight occurs when a person lacks conscious visual awareness yet can correctly respond to or identify visual information, usually…

Correct answer: Blindsight
  • A. Intensity
  • B. Color
  • C. Purity
  • D. Brightness

Explanation: Wavelength is the main physical property associated with hue, or perceived color, whereas intensity is related mainly to brightness.

Correct answer: Color
  • A. Under low levels of illumination
  • B. From very short distances
  • C. With one eye covered
  • D. In relation to surrounding objects

Explanation: Color constancy is strongest when an object is judged alongside surrounding objects, because the visual system uses the surrounding…

Correct answer: In relation to surrounding objects
  • A. Proximity
  • B. Relative clarity
  • C. Similarity
  • D. Connectedness

Explanation: The Gestalt principle of similarity groups items that share visual features, such as the red cardinals and brown cardinals being perceived…

Correct answer: Similarity
  • A. Shape constancy
  • B. The principle of continuity
  • C. Retinal disparity
  • D. The misperception of distance

Explanation: The Ames room illusion makes people appear to shrink or enlarge because the viewer incorrectly assumes the room has normal rectangular…

Correct answer: The misperception of distance
  • A. People tend to gravitate toward a common interaction distance
  • B. Objects nearer to each other appear closer to the person observing
  • C. Perception occurs in discrete time frames
  • D. Objects nearer to each other are seen as forming a unit

Explanation: Proximity means that elements close to one another are naturally perceived as belonging together, so nearby objects form a visual unit.

Correct answer: Objects nearer to each other are seen as forming a unit
  • A. Figure-ground
  • B. Symmetry
  • C. Similarity
  • D. Closure

Explanation: Closure leads the visual system to fill in missing portions and perceive an incomplete series of dots as a continuous line or whole…

Correct answer: Closure
  • A. What parts of the brain are used in speech production
  • B. The relationship between the wavelength of light and the experience of color
  • C. The effect of neurotransmitters on depression
  • D. Our psychological reactions to physical stress

Explanation: Psychophysics examines how measurable physical properties of stimuli relate to subjective experience, such as how light wavelength is…

Correct answer: The relationship between the wavelength of light and the experience of color
  • A. Prime theory
  • B. Opponent process theory
  • C. Signal detection theory
  • D. Frequency theory

Explanation: Signal detection theory explains how alertness, expectations, fatigue, and other psychological factors affect the detection of weak…

Correct answer: Signal detection theory
  • A. 1250 to be noticed
  • B. 1200 to be noticed
  • C. 1010 to be noticed
  • D. 1100 to be noticed

Explanation: Weber’s law predicts a roughly constant proportional difference threshold: a 10% increase from 100 to 110 Hz was needed, so 1000 Hz would…

Correct answer: 1100 to be noticed
  • A. Diminishing sensitivity to an unchanging stimulus
  • B. Adjustment in the opening of the eye
  • C. The process by which stimulus energies are changed into neural impulses
  • D. Changes in the shape of the lens as it focuses on objectsEnroll In Courses

Explanation: Sensory adaptation is the reduced responsiveness that develops when an unchanging stimulus remains present, such as becoming less aware of…

Correct answer: Diminishing sensitivity to an unchanging stimulus
