FOPAC EXAM - PERCEPTION + MEMORY AND COGNITION FINAL
EXAM
Question 1
The process by which physical energy (such as light waves or sound waves) is converted
into an electrochemical neural signal by sensory receptors is known as:
A) Perception
B) Transduction
C) Accommodation
D) Adaptation
E) Lateral Inhibition
Correct Answer: B) Transduction
Rationale: Transduction is the fundamental process in sensation where environmental
stimuli (light, sound, pressure) are converted into neural impulses that the brain can
interpret. Perception is the later process of organizing and interpreting those signals.
Question 2
You are looking at a star in the night sky. To see a dim star best, you should look slightly to
the side of it rather than directly at it. Why?
A) The fovea contains only cones, which are not sensitive in low light.
B) The fovea contains a blind spot where the optic nerve exits.
C) The periphery of the retina contains a higher density of cones.
D) Rods are concentrated in the fovea and are best for color vision.
E) The lens focuses light better on the periphery.
Correct Answer: A) The fovea contains only cones, which are not sensitive in low light.
Rationale: The fovea (center of the retina) is packed with cones, which require bright light
to function and provide color/detail. Rods, which are sensitive to dim light (scotopic vision),
are located primarily in the periphery of the retina. Looking to the side utilizes the rods.
Question 3
Which theory of color vision proposes that the retina contains three types of cones that are
maximally sensitive to red, green, and blue wavelengths?
A) Opponent-Process Theory
B) Frequency Theory
C) Place Theory
D) Young-Helmholtz Trichromatic Theory
E) Gate Control Theory
Correct Answer: D) Young-Helmholtz Trichromatic Theory
Rationale: The Trichromatic Theory states that color vision depends on the activity of three
,[Type here]
receptor types (S-cones, M-cones, L-cones) sensitive to short (blue), medium (green), and
long (red) wavelengths. Opponent-Process theory explains color vision at the level of the
ganglion cells and thalamus (afterimages).
Question 4
When you read a messy handwritten note, you are able to decipher the words because of
the context of the sentences, even if individual letters are ambiguous. This relies primarily
on:
A) Bottom-Up Processing
B) Top-Down Processing
C) Parallel Distributed Processing
D) Feature Detection
E) Transduction
Correct Answer: B) Top-Down Processing
Rationale: Top-down processing involves using pre-existing knowledge, context, and
expectations to interpret sensory information. Bottom-up processing would rely solely on
the raw data (the curves and lines of the letters) without context.
Question 5
The Gestalt principle of "Closure" refers to the tendency to:
A) Group objects that are close to one another.
B) Group objects that move in the same direction.
C) Fill in gaps in a visual image to perceive a complete, whole object.
D) Perceive objects as remaining constant in size despite changes in retinal image.
E) Distinguish a figure from its background.
Correct Answer: C) Fill in gaps in a visual image to perceive a complete, whole object.
Rationale: The Gestalt law of Closure describes the brain's tendency to "close the gaps" in
an incomplete figure (like a circle with a segment missing) to perceive it as a whole object.
Question 6
In the "Visual Cliff" experiment by Gibson and Walk, infants refused to crawl across the
glass surface that appeared to drop off. This experiment demonstrated that:
A) Depth perception is entirely learned through language.
B) Infants lack binocular disparity.
C) Depth perception has an innate or very early biological basis.
,[Type here]
D) Infants have poor visual acuity until age 2.
E) Fear of heights is a result of classical conditioning.
Correct Answer: C) Depth perception has an innate or very early biological basis.
Rationale: Because infants as young as 6 months (crawling age) refused to cross the "cliff,"
the study suggested that the ability to perceive depth is present very early in development,
likely having an innate biological component, though experience plays a role.
Question 7
Which of the following is a "Binocular" depth cue?
A) Linear Perspective
B) Retinal Disparity
C) Texture Gradient
D) Motion Parallax
E) Interposition
Correct Answer: B) Retinal Disparity
Rationale: Retinal disparity (or binocular disparity) relies on the fact that our two eyes are
separated by a few inches, providing two slightly different images to the brain. The brain
uses the difference to calculate depth. The other options are monocular cues.
Question 8
A patient suffers damage to the Fusiform Face Area (FFA) in the temporal lobe. They can
see objects clearly but cannot recognize the faces of their family members. This condition is
called:
A) Hemispatial Neglect
B) Prosopagnosia
C) Akinetopsia
D) Visual Agnosia (General)
E) Anterograde Amnesia
Correct Answer: B) Prosopagnosia
Rationale: Prosopagnosia (face blindness) is a specific type of visual agnosia where the
ability to recognize faces is impaired, often due to damage to the fusiform gyrus. The
patient typically recognizes people by voice or clothing.
Question 9
In Signal Detection Theory, if a signal is present (e.g., a tumor on an X-ray) and the doctor
correctly identifies it, this is called a:
, [Type here]
A) False Alarm
B) Correct Rejection
C) Miss
D) Hit
E) False Negative
Correct Answer: D) Hit
**Rationale: In Signal Detection Theory:
• Signal Present + Response Yes = Hit
• Signal Present + Response No = Miss
• Signal Absent + Response Yes = False Alarm
• Signal Absent + Response No = Correct Rejection**
Question 10
The "Cocktail Party Effect" demonstrates the human ability to:
A) Drink alcohol without losing cognitive function.
B) Focus auditory attention on one stimulus while filtering out other background noise.
C) Remember names of people introduced at a party.
D) Hear all conversations in a room simultaneously.
E) Use visual cues to aid hearing.
Correct Answer: B) Focus auditory attention on one stimulus while filtering out other
background noise.
Rationale: The Cocktail Party Effect describes the phenomenon of selective attention,
where one can attend to a single conversation in a noisy room, effectively "tuning out"
others, until a salient stimulus (like one's name) captures attention.
Question 11
Which component of Baddeley’s Working Memory Model is responsible for the temporary
storage and rehearsal of verbal/auditory information?
A) Visuospatial Sketchpad
B) Central Executive
C) Phonological Loop
D) Episodic Buffer
E) Sensory Register
Correct Answer: C) Phonological Loop
Rationale: The Phonological Loop handles auditory and verbal information (the "inner
