Why is social cognition considered more complex than physical cognition?
Social partners are self-propelled and unpredictable
Behaviour driven by hidden mental states (goals, beliefs, desires)
Requires inference about others’ minds
Must manage multiple individuals and competing motives
Why are early social skills important for later life outcomes?
Predict:
Number & quality of relationships
Academic & work success
Likelihood of criminal behaviour
Linked to:
Empathy
Perspective-taking
Cooperation & communication
What is the evolutionary problem human infants face?
Born extremely physically helpless
Cannot move, cling, or survive independently
Depend entirely on caregivers for survival
What evolutionary solution helps infants survive?
Develop mechanisms to promote bonding with caregivers
Ensure attention, protection, and care
What is “baby schema” and who proposed it?
Proposed by Konrad Lorenz
Features:
Big eyes, round face, chubby cheeks
Function:
Triggers caregiving behaviour in adults
What is bonding in humans?
First major social relationship (infant–caregiver)
Develops over time, not instantly
Is there a critical period for bonding in humans?
❌ No
Early belief based on flawed study
Bonds can form even after separation (e.g., adoption)
What is imprinting?
Rapid attachment to first moving object
Occurs in some animals (especially birds)
Happens in a critical period
Key features of imprinting?
Timing = fixed (hours/days after birth)
Target = flexible (mother, human, object)
Classic imprinting experiment?
Konrad Lorenz
Geese followed:
Mother (if hatched naturally)
Lorenz (if first seen)
Behaviour was irreversible
Why must human infants be especially social learners?
Need to learn:
Language
Cultural practices
Values & norms
Not just survival skills → culture-specific knowledge
When do foetuses start responding to sound?
Third trimester
What do foetuses hear most?
Mother’s voice (plus internal sounds)
Do newborns prefer their mother’s voice?
✅ Yes (within 2–3 days)
How was this tested?
Operant sucking paradigm
Babies suck differently to hear:
Mother vs stranger voice
What does this show?
Infants learn and prefer mother’s voice
Why is prenatal learning likely?
No preference for father’s voice early on
Suggests learning occurred in the womb
Evidence foetuses distinguish voices?
Different heart rate responses to:
Mother vs stranger voice
Study by Anthony DeCasper & William Fifer found what?
Newborns prefer mother’s voice
Will “work” to hear it
What did Anthony DeCasper & Melanie Spence show?
Foetuses learn specific stories (rhythm patterns)
Prefer them after birth (even read by stranger)
What did William James claim about infants?
Experience is a “blooming, buzzing confusion”
What did later research show instead?
Infants are competent and active learners
What method did Robert Fantz develop?
Preferential looking paradigm
Q: What did Fantz find?
Infants (2 days old) prefer:
Faces over non-face stimuli
What did Mark Johnson show?
Even 43-minute-old infants track face-like patterns more
Do infants recognise their mother’s face?
✅ Yes (1–3 days old)
Q: How quickly do infants learn their mother’s face?
After ~5.5 hours of exposure
What face features do infants prefer?
Direct gaze
Happy expressions
Q: Why is eye contact important?
Signals engagement and communication
Q: What visual limitation do infants have?
Nearsighted
Best vision: 7–10 inches (perfect for caregiver face)
What is neonatal imitation?
Infants copy facial actions:
Tongue protrusion
Mouth opening
Q: Key researchers?
Andrew Meltzoff & M. Keith Moore
Q: Why is imitation considered impressive?
Infants:
Have never seen their own face
Must match seen actions → felt movements
Called Active Intermodal Mapping
Q: What does imitation suggest (according to Meltzoff)?
Early understanding of self–other equivalence
Foundation for theory of mind
Q: Is neonatal imitation universally accepted?
❌ No (controversial)
Q: Problems with imitation findings?
Only ~50% of infants show it
Difficult to replicate
May be due to arousal, not imitation
Alternative explanation (Anna Field)?
Tongue protrusion = response to interesting stimuli, not imitation
Q: Evidence supporting arousal explanation?
Babies stick out tongues to:
Lights
Music (e.g., Barber of Seville)
Q: Is neonatal imitation linked to later imitation ability?
❌ No clear link
At what age do chimpanzees show face preferences?
Around 1 month old
What are infants biologically prepared to do socially?
Detect:
Faces
Voices
Eye contact
Emotions
Q: What can infants do from very early on?
Learn & remember social information
Prefer caregivers
Engage with social world
Q: What is the overall function of early social abilities?
Promote:
Bonding
Caregiver attention
Learning from others
When do infants begin true imitation? - what is imitation
A: Around 9 months (especially actions on objects)
Q: What type of imitation do infants show at 9 months?
A: Imitating actions on objects (e.g. pulling apart a toy)
Q: What is significant about infant imitation at 9 months?
A: They can remember and reproduce actions later (deferred imitation)
Q: Do apes imitate like humans?
A: Debate exists, but generally:
Humans → imitate
Apes → emulate
What is imitation?
A: Copying both:
Means (how)
End (goal)
What is emulation?
A: Reproducing the goal only, using own method
What is mimicry?
A: Copying actions only without understanding the goal
Key difference between human children and apes in learning?
A:
Humans → Imitation (means + goal)
Apes → Emulation (goal only)

A: Copying irrelevant/unnecessary actions
Q: At what age does overimitation occur?
A: Around 3–5 years
Q: Do children copy irrelevant actions even when they know they are unnecessary?
A: Yes
Q: Do chimpanzees overimitate?
A: No — they ignore irrelevant steps
Q: What does overimitation suggest about human cognition?
A: Strong tendency to faithfully copy others (possibly cultural learning)
What is cooperation in development?
A: Working together to achieve a shared goal
Q: When does cooperation emerge?
A: Around 14–18 months
Q: What is shared intentionality?
A: Sharing goals and intentions with another person
Q: What happens when an adult stops cooperating in experiments?
A: Children:
Try to re-engage the adult
Use communicative signals
Q: What motivates children to cooperate?
A: Intrinsic enjoyment (not just rewards)
Q: Evidence children enjoy cooperation?
A:
Put reward back to play again
Prefer cooperation even when they can do task alone
Q: How do chimpanzees perform in cooperation tasks?
A:
Less coordination
Little communication
Not interested in social games
Q: Is chimp cooperation debated?
A: Yes — some argue they cooperate in the wild (e.g. hunting)
What type of interaction is secondary intersubjectivity?
A: Triadic (person–person–object)
Q: What does secondary intersubjectivity involve?
A:
Sharing attention
Sharing emotions

A:
Joint attention
Gaze & point following
Social referencing
Intentional communication
Imitation
Cooperation
Q: Are these abilities unique to humans?
A:
Some (e.g. gaze following) → seen in animals
Others → debated or more advanced in humans
Q: What characterises the 9-month revolution overall?
A:
A shift to shared minds with others about the world
→ Infants begin:
Understanding others
Sharing attention & goals
Participating in social interactions actively
attachment and its signs
Attachment
Newborn infants show a preference for their mother’s face and voice
There is no specific attachment bond yet at birth
Attachment develops later in infancy
Attachment = strong emotional bond between infant and primary caregiver
Begins to develop around 7–9 months (just before the “9-month revolution”)
Signs of Attachment
Attempts to stay close to the caregiver
Separation anxiety (distress when caregiver leaves)
Starts around 8 months
Happiness when reunited with caregiver
theories of attachment
Theories of Attachment
Sigmund Freud – Drive Reduction Theory
Infants attach to caregivers because they satisfy biological needs (e.g., hunger, thirst)
Satisfaction of needs → pleasure → attachment
Behaviourist View
Caregivers become associated with reinforcement
Attachment forms because they reduce discomfort
John Bowlby – Ethological Theory
Caregivers are more than food sources
Provide a secure base for exploration
Attachment has an evolutionary function (survival + learning)
harry harlow monkey studies
Harry Harlow – Monkey Studies
Separated 8 infant monkeys from biological mothers shortly after birth
Each monkey placed in a cage with:
Wire mother (provided milk)
Cloth mother (soft, no food)
Findings:
Monkeys spent more time with cloth mother
Only went to wire mother briefly for feeding
When scared → ran to cloth mother
Cloth mother used as a secure base
Conclusion:
Attachment is based on comfort and security, not just food
Supports Bowlby’s theory
mary ainsworth - strange situation test
Mary Ainsworth – Strange Situation Test
Measures attachment style in human infants
Procedure includes:
Infant + caregiver play
Stranger enters
Caregiver leaves
Caregiver returns
attachment styles
Attachment Types
Secure Attachment
Uses caregiver as secure base
Explores environment confidently
Distressed when caregiver leaves
Happy when caregiver returns
Insecure Attachment
Avoidant
Little interest in caregiver
Minimal distress when they leave
Avoids contact when they return
Resistant / Ambivalent
Seeks contact but not comforted
Mixed emotional responses
Disorganised
No clear pattern of behaviour
Consequences of Disrupted Attachment
Consequences of Disrupted Attachment
Harlow’s monkeys → abnormal social development
Children raised in orphanages:
Impaired social, emotional, and cognitive development
Especially if adopted after 6 months
Early attachment affects future relationships
prosocial behaviour
Prosocial Behaviour
Voluntary behaviour intended to benefit others
Helping
Sharing
Comforting
Key Findings
Felix Warneken & Michael Tomasello
18-month-olds help others with tasks (instrumental helping)
Even 14-month-olds show some helping
Helping is:
Spontaneous
Done without being asked
Done without rewards
Can decrease if rewarded (extrinsic rewards reduce motivation)
Costly (children will make effort to help)
Humans may be naturally altruistic
Helping in Younger Infants
Liszkowski
12-month-olds help by providing information (e.g., pointing)
Antisocial Behaviour
Also common in children:
Aggression
Stealing
Teasing
Lying
Cheating
Theory of Mind (ToM) — Core Idea
Theory of Mind = ability to attribute mental states (beliefs, desires, intentions, emotions, knowledge) to:
Other people
Yourself
👉 These mental states are invisible, so we infer them to:
Explain behavior
Predict what someone will do next
Two Key Components of ToM
People have mental states (beliefs, desires, etc.)
Mental states can differ
From your own (you like broccoli, I don’t)
From reality (false beliefs)
Development Timeline (VERY IMPORTANT)
Focus on age ranges, not exact numbers:
Early abilities (≈ 6–12 months)
Understand:
Perception (what others see)
Attention (what others focus on)
Around 9 months (“9-month revolution”):
Joint attention; Shared focus between two individuals on an object, showing awareness of others’ attention.
Social referencing: Using others’ emotional reactions to guide your own behavior.
Goal understanding begins
Perception:
Knowing that others can see, hear, or perceive things.
Knowing that others selectively focus on certain aspects of their environment.
By ~12 months, infants understand that others attend selectively and use this to interpret ambiguous requests.
Goals vs Intentions (IMPORTANT distinction)
Goal = desired outcome
→ e.g., opening a box
Intention = plan to reach goal
→ e.g., using scissors vs hands
👉 Infants often understand goals first
Classic Study: Andrew Meltzoff
18-month-olds
See adult:
succeed OR
fail to open toy
👉 Infants imitate the goal, not the action
→ They open it even if adult failed
✔ Shows: understanding of intentions/goals
Understanding Intentions (Younger infants)
9-month-olds:
Distinguish:
Unwilling vs unable
wont give toy vs cant give toy
Show more frustration when:
Adult won’t give toy vs can’t - unwilling
✔ Also seen in chimpanzees
Emotions & Empathy Development:
Newborns: emotional contagion (not real empathy) - Automatic copying of others’ emotions (e.g., newborn crying when others cry)
~9 months: concern for others - true empathy begins
by 18 months - infants comfort others, infer emotions from context not just facial expressions
Can infer emotions even without facial cues
Desires (Classic Study) Betty Repacholi & Alison Gopnik
Broccoli vs crackers experiment
infants prefer crackers, experimenter prefers brocoli
Results:
18-month-olds → give experimenter what she likes
14-month-olds → give what they like
✔ Shows: Understanding that others’ desires ≠ own desires
👉 Chimpanzees:
Understand preferences somewhat
❌ Fail when desires differ from their own
False Belief - What is it?
belief that does nto match reality - strongest test of theory of mind
Understanding that:
Someone can believe something wrong
Classic Test: Sally-Anne
Sally puts object somewhere
It gets moved while she’s away
👉 Question: Where will Sally look?
Results:
❌ 3-year-olds fail (say real location)
✅ 4+ year-olds pass
Smarties Test (unexpected contents)
Box looks like candy but contains pencil
Results:
❌ Young children say:
others will say “pencil”
✅ Older children say:
others will say “candy”
Big Discovery: Implicit vs Explicit ToM Explicit ToM
Verbal answers required
Develops ~4 years
Implicit ToM
Measured via:
Looking
Helping behavior
Present as early as:
15–16 months
👉 Infants
Look where agent believes object is
Help based on false belief
Chimpanzees & ToM
Understand:
Goals
Intentions
Perception
Knowledge/ignorance
❌ Fail:
Explicit false belief tests
✅ Pass:
Implicit false belief tests
👉 Similar to human infants
What is the difference between intentional and unintentional communication in infants?
Newborns produce sounds like crying, which caregivers interpret (e.g., hunger, pain), but these are not intentional
Infants are not yet trying to communicate or influence others deliberately
Intentional communication requires:
The infant to direct signals toward a recipient (adult)
Not just toward a goal (e.g., reaching a cookie)
True intentional communication develops later, around 9–10 months, though earlier signs may exist
What are early indicators that an infant is communicating intentionally?
Gaze alternation between an object and an adult
Eye contact, especially “sensitive eye contact” (raised eyebrows, attention-seeking expression)
Use of facial expressions (e.g., frustration, smiling)
Vocalisations directed at the adult
Presence of an adult changes behaviour (vs. just reaching alone)
What are dyadic gestures and how do they differ from triadic gestures?
Dyadic gestures:
Involve only infant and caregiver
No reference to external objects
Examples:
“Pick me up” gesture
Waving “bye-bye”
May be ritualised or learned, not clearly intentional
Triadic gestures:
Involve infant, adult, and object/event
Clearly referential and intentional
Include:
Pointing
Showing
Giving
Often involve joint attention and gaze alternation
What are imperative and declarative gestures?
Imperative gestures (requests):
Used to get something
Examples:
Reaching for a cookie
Pointing to request an object
Function: “Give me that”
Declarative gestures (sharing attention):
Used to share interest or attention
Examples:
Pointing at something interesting
Showing an object to a caregiver
Function: “Look at that!”
What additional functions of gestures have been identified beyond imperative and declarative?
Informative gestures:
Help others by providing information (e.g., pointing to a lost object)
Questioning gestures:
Used to request information (e.g., “What is this?”)
Show that infant communication is more complex than originally thought
What are baby signs and what is their significance?
Gestures taught to infants (around 9–10 months) to communicate before speech
Can be:
Standard (e.g., “eat”, “all done”)
Invented by caregivers
Benefits:
Enable early communication
Allow infants to express needs and thoughts
Research findings are mixed:
Some studies suggest better vocabulary later
Others find no long-term advantage
Still considered useful and rewarding
What are iconic (pantomiming) gestures and when do they emerge?
Gestures that represent actions or objects visually
Example: flapping arms for a bird
Often emerge around 2–3 years
Can be:
Learned from caregivers
Invented by children themselves
Demonstrate symbolic and representational thinking
How do children demonstrate the ability to invent new gestures?
In experiments:
Children observed how a toy worked
Then had to teach a puppet without physical interaction
They used novel pantomime gestures to communicate
Shows:
Ability to create new communicative symbols
Understanding of others’ needs
How does chimpanzee gestural communication compare to humans?
Similarities:
Intentional and referential
Sensitive to attention and knowledge of others
Flexible use of gestures
Differences:
Mostly imperative (requesting), rarely declarative
Rarely share attention just for social purposes
Less frequent iconic gestures
What is a key difference between human and chimpanzee communication?
Humans:
Frequently use declarative gestures (sharing interest)
Chimpanzees:
Mostly use imperative gestures (requests)
Declarative communication is very rare
This difference is considered fundamental in human communication development
What are vervet monkey alarm calls and why are they important?
Vervet monkeys have distinct calls for different predators:
Eagle → look up, hide in middle of tree
Leopard → climb high into trees
Python → stand up, scan ground
Each call triggers a specific adaptive response
What did playback experiments reveal about vervet monkey calls?
Researchers played recorded calls without real predators
Monkeys responded appropriately to each call
Suggests calls are:
Functionally referential
Not just general fear or arousal signals
Unclear if monkeys intend meaning, but signals act like “words”
How does language development begin in infants?
Starts with comprehension before production
Early stage:
Discrimination of speech sounds
Infants initially:
Can distinguish all phonetic contrasts
Over time:
Lose sensitivity to non-native sounds
Why are infants better than adults at distinguishing speech sounds?
Infants:
Sensitive to all possible speech sounds
Adults:
Specialised for native language only
Example:
Japanese adults struggle with R vs L
Japanese infants can distinguish them early on
When do infants begin to understand words?
Around 8–12 months
Begin linking sounds to meanings
Marks transition from pure perception to language comprehension
What are the stages of language production in early development?
Crying:
Present from birth
Not intentional communication
Cooing and early sounds:
Gurgles, squeaks
No linguistic meaning
Babbling (around 6 months):
Repetitive sounds (e.g., “bababa”)
Practice of speech sounds
No meaning yet
What is babbling and why is it important?
Repetitive vocal play with speech-like sounds
Examples:
“mamama”, “bababa”
Functions:
Practice for speech production
Exploration of vocal abilities
Not yet intentional communication
When do infants produce their first words and what are they like?
Around 12 months (range: 9–17 months)
Characteristics:
Single-word utterances
Represent whole ideas
Example: “up” = “pick me up”
Usually refer to:
Familiar people
Objects
Basic needs
What is telegraphic speech?
Early multi-word speech with missing grammatical elements
Focus on key content words
Example:
“where ball” instead of “where is the ball”
Shows emerging syntax without full grammar
What is the vocabulary spurt?
Rapid increase in number of words learned
Occurs after first words (timing varies widely)
Some children:
Show early rapid growth
Others:
Develop gradually
Both patterns are normal
How large can children’s vocabularies become by age five?
Up to ~10,000 words
Demonstrates rapid and efficient word learning ability
What are individual differences in language development?
Large variability is normal
Examples:
First word: 9–17 months
Vocabulary spurt timing varies widely
No need for concern unless delays are extreme
How do children learn grammatical rules?
Develop abstract rules, not just memorisation
Apply rules to new (novel) words
Demonstrates understanding beyond imitation
What is the Wug Test and what does it show?
Children are shown a novel object (“wug”)
Asked to produce plural form
Correct response: “wugs”
Shows:
Knowledge of plural rule (add -s)
Ability to generalise rules
What is overgeneralisation (overregularisation) in language development?
Applying rules too broadly
Examples:
“foots” instead of feet
“mouses” instead of mice
“goed” instead of went
Indicates:
Active use of learned grammatical rules
Not just imitation
What is notable about infants' language development in the first year?
Many infants produce their first words before their first birthday.
At this stage, they are still very young: barely walking, still in nappies, and learning basic routines.
Language production starts early, laying the foundation for combining words into sentences.
How advanced is language by age five?
Children may know up to 10,000 words.
They can combine words to form an infinite number of novel sentences using grammar.
Grammar is complex and often learned naturally, unlike the effort required when learning a second language.
How do behaviourists explain language acquisition?
Language is a behaviour learned like any other.
Acquired through:
Classical conditioning: associating sounds with objects (e.g., “shoe” = object).
Operant conditioning: selective reinforcement of correct or close vocalisations by caregivers.
Imitation: children reproduce sounds and words they hear.
Problems:
Parents rarely reinforce grammatical correctness; focus is on meaning or truth.
Children often over-regularize (e.g., “mouses”) or create novel sentences adults haven’t modeled.
What are the key limitations of the behaviourist theory?
Positive reinforcement often targets meaning rather than grammar.
Corrections by adults have limited immediate impact.
Children produce novel grammatical structures, which cannot be learned solely through imitation.
What is the nativist theory of language acquisition (Noam Chomsky)?
Language is an innate human ability; unique to humans.
Children learn complex grammar quickly and effortlessly between ages 1–2.
Key ideas:
Poverty of the stimulus: children learn from incomplete, messy language input.
Language Acquisition Device (LAD): innate brain structure pre-programmed with universal grammar rules.
Children select rules from universal grammar relevant to their native language.
Problems:
LAD has never been located in the brain.
Children often receive simplified, clear “child-directed speech” (Motherese), contradicting the poverty of stimulus claim.
What is child-directed speech (Motherese)?
Slow, high-pitched, clearly enunciated speech with exaggerated intonation.
Uses simple words and well-formed utterances.
Captures infant attention, supporting language learning.
How do parents provide indirect feedback to support language development?
Recasts: repeating the child’s utterance with correct grammar or elaboration.
Example: Child says “ball fall,” adult says “Yes, the ball fell.”
Clarification requests: adults ask for clarification without explicitly correcting grammar.
Provides subtle guidance without negative reinforcement.
What is the social interactionist (pragmatic) theory of language acquisition?
Language is learned in naturally occurring social interactions.
Children learn by:
Understanding adults’ intentions and goals.
Engaging in joint attention and imitating speech.
Adults scaffold learning by:
Naming objects in routines.
Following the child’s focus of attention.
Jerome Bruner called this the Language Acquisition Support System (LASS).
How do children figure out the meaning of novel words?
Social-pragmatic approach: children use context, routines, gaze-following, and adult intentions.
Nativist approach: innate constraints on word learning:
Whole-object bias: novel words refer to entire objects rather than parts.
Mutual exclusivity: objects have only one label; new words refer to unfamiliar objects or aspects.
Experiments show 18–24 month olds use social cues to identify new words and actions.
How can adults facilitate language acquisition in young children?
Use child-directed speech (Motherese).
Adjust speech to the child’s level (Vygotsky’s Zone of Proximal Development).
Use routines and scaffolding during everyday interactions (bathing, eating, etc.).
Follow the child’s focus of attention when introducing new words.
Read and talk to children frequently to enhance vocabulary growth.
Early exposure is crucial for second language acquisition; younger learners achieve native-level fluency more easily.
What happens when children are deprived of language input early?
Feral or neglected children may fail to develop normal language competence, especially grammar.
Deaf children not exposed to sign language early struggle with full language development.
How do social cues help with verb learning?
Children can infer the meaning of a novel verb from intentional actions of adults.
Example: adult performs intentional action while naming it; children map the word to that action.
What is moral development and how is it defined in developmental psychology?
The developmental process by which individuals understand what their culture or society considers right and wrong, or good and bad.
Includes both reasoning about actions and the internalization of social norms.
Starts in infancy but continues through childhood and adolescence.
How did Piaget describe moral development in children?
Morality develops in stages, linked to cognitive development.
Pre-moral (up to ~4 years): Children have no moral principles.
Heteronomous morality (4–10 years): Focus on consequences, not intentions; naughtiness judged by outcomes.
Autonomous morality (~10+ years): Children consider intentions rather than just consequences.
Used story vignettes (e.g., boys breaking cups) to test moral reasoning.
Younger children judged severity by outcome (15 cups vs. 1 cup), older children considered intentions.
Problems:
Stages often proposed too late in age.
Young children actually consider intentions in real-world contexts.
Relies on verbal stories, which may not reflect real behavior.
How did Kohlberg expand on moral development?
Built on Piaget but created a stage theory with three main levels:
Pre-conventional (up to ~9–10 years): Morality based on avoiding punishment or seeking reward.
Conventional (~10–12 years): Morality based on obeying rules and social approval.
Post-conventional (~12+ years): Morality based on abstract principles, possibly overriding rules if necessary.
Famous test: Heinz dilemma (stealing drug to save a wife).
Problems with Kohlberg:
Stages not always clear-cut.
Difficult to score responses reliably.
Assumes universality across cultures, which is not supported.
Verbal hypotheticals may not match real behavior.
What evidence shows infants have a basic sense of morality?
Six- to ten-month-old infants prefer “helpers” over “hinderers.”
One-year-olds expect fair resource distribution and prefer fair actors.
Children show anger or protest when moral or conventional norms are violated (strong indicator of understanding).
How do young children demonstrate understanding of conventional norms?
Example: Daxing study (children correct puppets doing a task incorrectly).
Children as young as 2–3 years protest or show strong reactions when social norms are violated.
Indicates early understanding of “how things should be done,” separate from abstract moral reasoning.
When do children start showing preferences for in-group members?
Very young infants (6 months) prefer people who speak their native language.
10-month-olds preferentially accept toys from native language speakers.
14 months: selectively imitate actions of in-group members.
3–5 years: prefer minimal, arbitrarily assigned in-group members (colors, teams).
How do children demonstrate in-group favoritism in minimal group paradigms?
Assigned to a group based on arbitrary criteria (e.g., color).
Show more helping, sharing, trust, and liking towards in-group members.
Preference appears within minutes of assignment.
Measured via puppets, toys, or drawing tasks.
How does race and familiarity affect in-group preferences?
3-month-olds: preferentially look at same-race faces.
10-month-olds: take toys equally from same and other races.
2.5-year-olds: distribute toys equally across races.
~5 years: show preferential treatment for same-race individuals.
Early racial preferences may be influenced by familiarity or parental cues rather than innate bias.
