Question 1 of 16

All Questions (16)

A person assembling a puzzle for the first time with no picture to guide them relies on the shapes and colors of the individual pieces to build the image. This approach is an example of:

A) Top-down processing

B) Bottom-up processing

C) Selective attention

D) Perceptual constancy

Correct Answer: B

Bottom-up processing involves building perceptions directly from sensory information. In this case, the perception of the final image is constructed piece by piece from the raw sensory data (shape, color) without any guiding prior expectations.

After watching a scary movie, a person is more likely to interpret a creaking floorboard as an intruder rather than the house settling. This is best explained by the influence of:

A) A perceptual set

B) Retinal disparity

C) The cocktail party effect

D) The principle of closure

Correct Answer: A

A perceptual set is an internal factor, a mental predisposition to perceive one thing and not another. The scary movie created an expectation (a set) for threatening stimuli, which filtered the perception of the ambiguous sound.

When viewing a crowd, we tend to perceive individuals standing close to each other as being part of a group. Which Gestalt principle best explains this phenomenon?

A) Closure

B) Similarity

C) Figure-ground

D) Proximity

Correct Answer: D

The Gestalt principle of proximity states that we group nearby figures together. Because the individuals are physically close to one another, we perceptually organize them into a single unit or group.

At a noisy party, you are able to focus on a conversation with a friend while filtering out all the other conversations and music around you. This ability is a classic example of:

A) Change blindness

B) The cocktail party effect

C) Perceptual constancy

D) Convergence

Correct Answer: B

The cocktail party effect is a prime example of selective attention, which is the ability to focus on a particular stimulus while filtering out others in a complex environment.

Which of the following is a depth cue that requires the use of both eyes to process?

A) Linear perspective

B) Relative size

C) Convergence

D) Apparent movement

Correct Answer: C

Convergence is a binocular depth cue. It refers to the inward turn of the eyes that occurs when they focus on a nearby object; the brain notes the angle of convergence to gauge distance. Linear perspective and relative size are monocular cues.

A researcher asks a participant for directions. During the conversation, two people carrying a large board walk between them, and the researcher is replaced by a different person. The participant often fails to notice the change. This phenomenon is called:

A) Selective attention

B) A perceptual set

C) Change blindness

D) Retinal disparity

Correct Answer: C

Change blindness is a form of inattention where an individual fails to notice a significant change in their visual environment because their attention is focused on another task (in this case, giving directions).

An artist creates the illusion of depth on a flat canvas by painting parallel lines, such as a road or railroad tracks, as if they meet in the distance. Which monocular depth cue is being used?

A) Relative size

B) Proximity

C) Linear perspective

D) Closure

Correct Answer: C

Linear perspective is a monocular cue where parallel lines appear to converge in the distance. This visual trick is used to give the illusion of depth on a 2D surface.

According to the provided content, which of the following is an example of an internal factor that filters perception?

A) Schemas

B) Context

C) Culture

D) Experiences

Correct Answer: A

The content explicitly lists schemas and perceptual sets as internal factors that filter perceptions. Context, culture, and experiences are listed as external factors.

As a car drives away from you, the image it casts on your retina gets smaller, yet you do not perceive the car as shrinking. This is due to:

A) Retinal disparity

B) Perceptual constancy

C) Apparent movement

D) Change blindness

Correct Answer: B

Perceptual constancies (in this case, size constancy) are top-down processes that allow us to perceive objects as unchanging in size, shape, and color, despite changes in the sensory information reaching our eyes.

When you look at a page of a book, you perceive the words as distinct from the white paper they are printed on. This organization of your perception is best described by the Gestalt principle of:

A) Figure-ground

B) Proximity

C) Similarity

D) Closure

Correct Answer: A

The figure-ground principle explains our perceptual tendency to organize stimuli into a central object (the figure, which is the text) that stands out from its surroundings (the ground, which is the white page).

If you see a series of dashes arranged in the shape of a circle, you are likely to perceive it as a complete circle rather than a set of disconnected lines. This is due to the Gestalt principle of:

A) Proximity

B) Similarity

C) Closure

D) Figure-ground

Correct Answer: C

The Gestalt principle of closure states that our minds tend to fill in gaps in visual information to perceive objects as complete rather than as a series of separate parts.

Retinal disparity and convergence are both binocular cues for depth. Retinal disparity refers to the ____, while convergence refers to the ____.

A) inward turn of the eyes; difference between the images in each eye

B) perception of movement; illusion of depth on a 2D surface

C) difference between the images in each eye; inward turn of the eyes

D) reliance on prior expectations; reliance on sensory information

Correct Answer: C

Retinal disparity is the binocular cue resulting from the slightly different images projected onto each retina because of their different positions. Convergence is the cue based on the extent to which the eyes turn inward when looking at an object.

A series of still images, such as lights on a theater marquee flashing in sequence, can create the illusion of motion. This phenomenon is known as:

A) Perceptual constancy

B) Change blindness

C) Apparent movement

D) Linear perspective

Correct Answer: C

Apparent movement is the perception of movement in objects that are, in fact, stationary. This illusion is created by presenting a rapid succession of still images, which the brain interprets as continuous motion.

Reading a sentence with several misspelled words is often easy because our brain uses existing knowledge of language and words to interpret the text correctly. This process is a clear example of:

A) Bottom-up processing relying solely on sensory data

B) Top-down processing guided by schemas

C) The Gestalt principle of proximity

D) A binocular depth cue

Correct Answer: B

Top-down processing uses prior expectations, knowledge, and context (our schemas for language) to interpret incoming sensory information. This allows us to overlook spelling errors and understand the intended meaning.

A person sees a long, thin object in the grass. If they are in their backyard, they might perceive it as a garden hose. If they are hiking in the woods, they might perceive it as a snake. This difference in perception, based on the setting, highlights the influence of which external factor?

A) Retinal disparity

B) Context

C) Closure

D) Perceptual constancy

Correct Answer: B

The context, an external factor, creates an expectation that influences how an ambiguous visual stimulus is interpreted. The setting (backyard vs. woods) primes the brain for different possibilities, demonstrating top-down influence on perception.

A person from a culture that does not frequently use rectangular architecture may be less susceptible to the Müller-Lyer illusion. This demonstrates how perception can be influenced by:

A) Binocular depth cues

B) The cocktail party effect

C) Culturally-based experiences and schemas

D) The Gestalt principle of closure

Correct Answer: C

This is a classic example of how external factors, such as one's culture and daily experiences, shape the internal schemas used for top-down processing. This leads to different interpretations of the same visual stimulus and can produce incorrect interpretations (illusions).
