Behavioral Science: Development 1 & 2 Flashcards
Definitions of premature birth, very premature birth
premature =
APGAR score
A- appearance (color) P- pulse G- grimace A- activity (muscle tone) R- respiration
Used to predict likelihood of immediate survival
US birth outcomes
High rate of premature births, so high infant mortality rate compared to other developed countries
Low income –> premature births + infant mortality
Baby blues
exaggerated emotionality and tearfulness for a few days after birth
post-partum depression
Major Depression that occurs in up to 10% of new mothers within 1 month of childbirth, can persist for up to 1 year
What direction do babies develop?
Cephalad to caudad, central to peripheral
- self to others, understanding to expressing
What happens from infancy to 18 mos?
- Humans need and seek the presence of others
- Attachment
- Social smile at 12 weeks
- Stranger anxiety at 9 months
- Separation anxiety late in first year, object permanence comes first
Importance of attachment
- psychoimmunology
- resulted in the concept of foster families
Infant reflexes
Rooting: touch cheek, turns toward nip
Palmar Grasp: grips any object put in palm
Moro: limbs extend when startles
Babinski: dorsiflexion of toes when sole of foot stroked (until 1 yr)
Milestones from 18 months to age 5
Rapprochment: moves away but quickly returns for comfort
Age 2: “NO”
Age 3: can spend a few hours away from mom, gender identity
Age 4: Bowel function
Age 5: bladder function
Preschool child (ages 3-6)
Sibling rivalry, regression.
- Between 2-4 vocabulary increases a shit ton

6 year old milestones
- development of conscience (superego)
- morality, empathy, right vs. wrong, finality of death
Autism Spectrum Disorders
- don’t acquire verbal and social skills at expected age
- seen before age 3
- no finger pointing (theory of mind)
- 50% have intellectual impairment
- more common in boys
- larger head circumference
- genetic component (associated w/ tuberous sclerosis and Fragile X)
Rett’s Disorder
4 years of normal functioning –>
hand wringing, breathing problems, intellectual impairment, ataxia, motor and social decline
- X linked
Childhood Disintegrative Disorder age
2-10 years of normal development
School age (7-11) and adolescence
- psychosexual issues dormant
- industry vs inferiority
- lifelong sense of competence
- concrete operations
- learning problems identified
School age (7-11) peer relationships
- relationships with adults other than primary caregiver

- not fitting in
- sexual latency, identifying with same sex parent
- morality, rule conscious (by 12 more flexible)
- more complex tasks (team sports)
- better at dealing with illness and hospitalization
- acting out as defense mechanism
- age 9: universality of death
Changes to brain during adolescence (11-20)
- myelination
- frontal and parietal lobes
- pruning of up to 50% of synaptic connections, decline in glucose and oxygen metabolism
Puberty milestones
- 5 in girls, 11.5 in boys
- first menstruation 11-14
- first ejaculation 12-15
- complete by 13.5 in girls, 15 in males
Factors the predispose to teen pregnancy
- depression
- poor school achievement
- divorced parents
Down syndrome
- single palmar transverse crease, protruding tongue, flat facies, hypotonia, epicanthal folds, small ears, thick neck, premature aging and Alzheimer’s disease
Fragile X Syndrome
Affects males more severely
- delayed cognitive function, hyperactive, hand flapping, hyperextensible joints, large ears, elongated face, postpubertal enlargement of testes
Phonological disorders
Leaves out or misplaces speech sounds, ie “ca” for cat, “top” for stop
Articulation disorders
Unable to make necessary motor movements for accurate speech production, ie lisping
