What is habituation in infant perception studies?
A. The tendency to look longer at new stimuli.
B. The process of losing interest in repeated stimuli.
C. The ability to differentiate between two objects.
D. The reaction to unexpected events.
B. The process of losing interest in repeated stimuli.
Explanation: Habituation occurs when an infant looks less at a stimulus after repeated exposure, indicating they recognize and remember it
What does dishabituation signify in an infant perception study?
A. A failure to recognize a new stimulus.
B. A return of interest when a new stimulus is introduced.
C. A consistent gaze duration for all stimuli.
D. A refusal to engage with the experiment.
B. A return of interest when a new stimulus is introduced.
Explanation: Dishabituation indicates that the infant notices a change in the stimulus, suggesting they can distinguish between the original and new stimuli.
In violation of expectation experiments, how do researchers infer surprise?
A. By measuring vocal responses.
B. By tracking the length of the infant’s gaze.
C. By observing changes in motor behavior.
D. By testing verbal understanding.
B. By tracking the length of the infant’s gaze.
Explanation: Researchers use the duration of gaze as a measure of surprise, as longer looking times indicate unexpected or novel events.
What principle can 8-month-old infants understand, as shown in violation of expectation experiments?
A. Object permanence
B. Conservation of mass
C. Abstract reasoning
D. Complex problem-solving
A. Object permanence
Explanation: By 8 months, infants understand object permanence—the concept that objects continue to exist even when out of sight.
How do preference studies reveal infant perception?
A. By observing which image an infant consistently avoids.
B. By tracking the longer gaze duration on a preferred stimulus.
C. By recording the infant’s verbal preference.
D. By measuring how often the infant cries.
B. By tracking the longer gaze duration on a preferred stimulus.
Explanation: Preference studies show which stimulus an infant prefers based on the length of time they look at it.
What does the visual cliff experiment test?
A. Depth perception and cautious behavior.
B. Recognition of objects and colors.
C. Ability to differentiate between sounds.
D. Memory retention over time.
A. Depth perception and cautious behavior.
Explanation: The visual cliff experiment assesses whether infants can perceive depth and whether locomotion experience influences their cautious behavior.
( also social referencing)
In the visual cliff experiment, why might infants refuse to cross the glass platform?
A. They are scared of the glass surface.
B. They lack physical ability to crawl.
C. They perceive the drop and act cautiously based on experience.
D. They cannot recognize differences in surfaces.
C. They perceive the drop and act cautiously based on experience.
Explanation: Infants use their locomotion experience to understand their physical abilities and the environmental risks, leading to cautious decisions.
How does high amplitude sucking help detect infant preferences?
A. By observing how quickly infants stop sucking.
B. By tracking the increase in sucking rate when exposed to preferred stimuli.
C. By comparing the intensity of cries during sucking.
D. By measuring the duration of sleep following suckin
B. By tracking the increase in sucking rate when exposed to preferred stimuli.
Explanation: High amplitude sucking measures infants’ preferences by observing increased sucking in response to rewarding stimuli, such as pleasant sound
What does it mean if an infant speeds up their sucking during a high amplitude sucking experiment?
A. They are hungry.
B. They are uninterested in the presented stimulus.
C. They prefer the stimulus being presented.
D. They are experiencing discomfor
C. They prefer the stimulus being presented.
Explanation: Increased sucking indicates that the infant finds the stimulus rewarding or interesting.
What does it mean when an infant gazes longer at a novel image in preference studies?
A. They are experiencing discomfort.
B. They recognize the novelty and find it interesting.
C. They are unable to differentiate between the images.
D. They prefer familiar stimuli over new ones
B. They recognize the novelty and find it interesting.
Explanation: Longer gaze duration at a new image reflects an infant’s ability to detect and show interest in novelty
How does habituation help researchers study infant memory?
A. By showing infants are unable to retain information.
B. By demonstrating that infants recognize and remember familiar stimuli.
C. By testing how infants respond to punishment.
D. By focusing only on physical abilities.
B. By demonstrating that infants recognize and remember familiar stimuli.
Explanation: Habituation indicates memory, as infants look less at stimuli they recognize and remember.
In violation of expectation studies, what might surprise an infant?
A. A predictable sequence of events.
B. An object falling according to gravity.
C. An impossible event, such as an object passing through another solid object.
D. A repetitive sound patter
C. An impossible event, such as an object passing through another solid object.
Explanation: Infants are surprised by events that violate their understanding of physical laws, like solidity or gravity.
Why is the sucking paradigm effective for studying infant preferences?
A. Infants’ sucking rate is involuntary and linked to stimuli they find rewarding.
B. Infants naturally suck faster when they dislike something.
C. Sucking rate does not correlate with preference.
D. Sucking is unrelated to cognitive abilitie
A. Infants’ sucking rate is involuntary and linked to stimuli they find rewarding.
Explanation: The sucking paradigm leverages the natural sucking reflex to assess preferences and interests in stimuli
Why might introducing salty foods before 4 months of age be ineffective for taste training?
a) Newborns cannot differentiate salty tastes until 4 months
b) Salt is harmful to newborns’ health
c) Salty foods taste the same as sweet to newborns
d) Salt reduces a newborn’s appetite
a) Newborns cannot differentiate salty tastes until 4 months
Why might a newborn fail to respond to a quiet sound that an adult can hear?
a) Newborns have underdeveloped hearing
b) Newborns are uninterested in quiet sounds
c) Newborns only respond to loud noises
d) Newborns are not yet capable of hearing at birth
) Newborns have underdeveloped hearing
Although they can hear from the third trimester, newborns’ auditory systems are not as sensitive as adults’.
A baby turns toward a familiar perfume scent but away from a bitter smell. What does this behavior indicate about sensory development?
a) Newborns are highly adaptable to all smells
b) Newborns prefer familiar and pleasant smells
c) Newborns cannot differentiate between smells
d) Newborns dislike all strong scent
b) Newborns prefer familiar and pleasant smell
If a newborn’s exposure to touch is limited, how might this affect their sensory and cognitive development?
a) They may have difficulty recognizing objects later
b) They may develop stronger auditory senses instead
c) Their sensory development is unaffected by touch
d) They will only rely on taste and smell for exploration
a) They may have difficulty recognizing objects later
Explanation: Touch is essential for learning and exploration in newborns , and limited exposure can hinder cognitive development
If a newborn is unable to hear quiet sounds but responds to louder ones, what does this indicate about their auditory threshold?
a) They have hearing impairment
b) Their auditory threshold is higher than adults
c) They cannot hear sounds at all
d) They can only hear sounds with high pitches
b) Their auditory threshold is higher than adults
Explanation: The quietest sound a newborn responds to is about four times louder than the quietest sound an adult can hear, reflecting a higher auditory threshold.
Auditory threshold refers to the quietest sound that can be reliably heard.
For newborns, their auditory threshold is higher, meaning they require louder sounds to perceive them compared to adults, whose auditory threshold is lower
Why might an infant respond more to human speech than to other sounds?
a) They are familiar with speech from the womb
b) Their hearing is naturally tuned to the pitch of human speech
c) They dislike non-human sounds
d) Their auditory development only recognizes the familiar voice
b) Their hearing is naturally tuned to the pitch of human speech
At what age can a child hear as well as an adult?
a) At birth
b) Around 3 years old
c) At 10 years old
d) By 6 months
c) At 10 years old
If a newborn is unable to see objects clearly farther than 4 inches, what should a caregiver do to maximize visual interaction?
a) Place objects far away to encourage focus
b) Keep their face within 4–30 inches from the infant
c) Avoid visual interaction until vision improves
d) Rely on auditory interaction instead
b) Keep their face within 4–30 inches from the infant
Why do newborns initially focus on the hairline or outer edges of a face?
a) They cannot process detailed facial features
b) They are drawn to high-contrast areas
c) They lack interest in faces
d) Their vision is fully developed only by 1 year
b) They are drawn to high-contrast areas
Explanation: Newborns focus on the edges of faces, such as the hairline, due to their sensitivity to contrast.
What visual acuity does a newborn have compared to adults?
a) 20/20 vision like adults
b) 20/25 vision by birth
c) 20/400 to 20/800 vision, passing the threshold for legal blindness in adults
d) Perfect acuity but blurry due to immaturity
c) 20/400 to 20/800 vision, passing the threshold for legal blindness in adults
Explanation: Newborns have significantly lower visual acuity at birth, but this develops to 20/25 by 6 months and adult levels by 1 year
