Infant development (Cognitive and Social)

Remember Piaget?

Sensorimotor (0-2 yrs)

Preoperational (2-7 yrs)

Concrete Operational (7-11 yrs)

Formal Operational (Adolescence – Adulthood)

Remember Piaget?

Sensorimotor (0-2 yrs)

Preoperational (2-7 yrs)

Concrete Operational (7-11 yrs)

Formal Operational (Adolescence – Adulthood)

Primary = Body focused (thumb sucking)

Secondary= Object focused (shaking rattle)

Just tryin’ stuff out

Mental Representation

Develops during Beginnings of Thought substage

Ability to develop internal images or past events or hypotheticals

Demonstrated by deferred imitation- child imitates a person who is not there

How might a behaviorist explain these abilities?

Critiques of Piaget

Me: Behaviorism provides other explanations

Lack of object permanence could be lack of motor skills, could be poor memory, not lack of mental imagery

Baillargeon violation-of-expectation studies- 3.5 months

Babies respond when they see impossible things

Information Processing

Asks how we take in, use, and store information

Measures quantitative changes in infant’ abilities to organize and manipulate information

So faster, more sophisticated, and more capacity = more developed

Encoding

Initial recording, what we take in

Selective- Example

Memory

Recording, storing, and retrieval is Memory

Memory is hard to measure in infants, but gets stronger over time

Hints help infants remember better (no duh)

Remember very little before age 3 – infantile amnesia

There is evidence of memories in infants, but it fades without language and becomes less detailed

Types of Memory

Explicit- intentional recall (George Washington’s birthday)

New Brain- Hippocampus and various parts of cortex

6months+

Implicit- unconscious memory (How to throw/catch)

Deep brain- cerebellum and brain stem

Earliest memories

intelligence

Can’t ask them questions

Motor, language, adaptive behavior, social behavior

Sensation, perception, memory, learning, problem solving

Views on intelligence

Info Processing: Efficient processing signals intelligence

How quickly infants:

Solve a problem

Attend to new or old stimuli

Multimodal Approach to Perception

Recognize objects using once sense, when they were only perceived with another

Language

Phonemes- single sounds (a, e, i, o, u)

Morphemes- smallest sounds with meaning (-ing, -s, -ed)

Semantics- Rules for langauge

Comprehension

Comprehension comes before production

22 new words per month comprehended

9 new words spoken per month when speech begins

Prelinguistic Communication

Weird baby sounds that don’t mean anything that we respond to

Different noises for different objects

Repetition develops ability to produce variety of noises for speech

Babbling- even deaf children babble with sign language

Begins to sound like language at 6 months

First 50 words

First words are around 10-14 months

Nominal words – 60%

Verbs – 20%

Modifiers – 10%

Social words – 10%

At 18 -24 months- learn up to 400 words

Holophrases- one word says it all

First Sentences

Typically observations, typically subject-verb

“Ball bounce” for “the ball bounced”

Telegraphic speech- basically broken English

Underextension- words not generalized appropriately

Blankie only used for a particular blanket

Overextension- words used too broadly

Everything with 4 wheels is a car

Language Styles

Referential- descriptions and labeling

Expressive- wants, desires, feelings

Cultural differences account for differences in style

Language Development- Behaviorism

Speech = stimulus, elicits a response, that response is a stimulus for another response.

If child is understood, response is reinforced

If child is misunderstood, response is not reinforced

Parents still understand their children when they use wrong syntax, so aren’t mistakes also reinforced?

Yes, but less frequently, and we correct speech

Correct speech gets us what we want faster, different schedule of reinforcement

Language Development- Nativist

Noam Chomsky argues we have innate language abilities

Universal Grammar- all language shares a structure

Language Acquisition Device- neural system allowing that facilitates language learning

Genetics backs this up

Language Development- Interactionist

Genetics + environment leads to language development

Innate ability fostered by social environment

Social needs drive motivation to acquire language

Infant-Directed speech

aka Motherese

Short, high pitched sentences, repetition

We know infants are more sensitive to higher and lower ranges, so this might actually be easier to understand

This tends to fade after 1st year

Sexism in our language

Boys and girls are taught different words, more diminutive words for girls (doggie, kitty, birdie)

Boys are told no, girls are given suggestions

More referential speech is used with girls

Social and Personality Development

Infant Emotions

Facial expressions are universal signs of emotional states

Interest, distress, disgust – at birth

Social smile, anger, surprise, sadness – 4 months

Fear, shame, shyness – 5-6 months

Contempt, guilt – 2 years

The feely Part of the emotions

Biological arousal

Cognitive

Behavioral

Fear?

Sadness?

Happiness?

Anxiety

Stranger anxiety- Strange Situation

Separation anxiety

Recognizing emotions

At 8 weeks, infants cant really see facial expressions

Social referencing- infants check in with others to make sense of an event

Awareness and Mind

Infants are self aware by around 12 months

2-year-olds have a sense of their abilities prior to trying a task

Infants develop a sense that other people think over time

18 month olds realize people will do stuff if you ask

They also realize only certain moving things are alive

1 year olds understand helping

2 year olds have empathy, will also begin to lie

Attachment

Avoidant

Secure

Ambivalent

Disorganized-disoriented

Role of Mothers

Certain behaviors are universal across cultures

Exaggerated facial expressions

Peek-a-boo

Mutual Regulation

Parents and children learn to express emotions and respond to each other

Fathers

They are important too

Substance use and depression are more highly correlated with father-child relationship than mother-child

Some infants primarily attach to fathers

Mothers tend to do more feeding/nurturing

Fathers tend to do more playing

Found across cultures

Infants and their peers

Infants recognize other infants, will interact with them

Familiar = more interactions

9-12 months: mutual sharing begins

14 months: peer-imitation

Personality and Temperament

Remember Erikson?

Erikson and Infants

Trust vs Mistrust

Needs met? Basic sense of trust develops

Autonomy vs. Shame and Doubt

Exploring boundaries- encouraged or restricted

Temperament

Long-lasting patterns of arousal and emotionality

Easy

Difficult

Slow-to-Warm

Easy Temperament

40% of babies

Positive, good bodily cycle, adaptable, curious

Difficult Temperament

10% of babies

Slow to adapt, withdraw in unfamiliar situations, highly reactive

Slow-To-Warm Temperament

15% of infants

Negative moods, slow adapters, calm but slow to interact with others and new situations

Gender Roles

Gender is our sense of being male or female

Different than sex- which is biological

Infants distinguish gender by 1st year

Develop preference for gendered toys

Boys are more stereotyped than girls

Girls are “protected” more during first steps, boys are encouraged to explore
