human development Flashcards
Nature and nurture influence human growth in which three domains
Physical, socio-emotional and cognitive.
What are the 3 periods of physical growth in the prenatal period?
The germinal period (when sperm unites with the egg from the female) (2 weeks) if pb-> miscarriage ;
- The embryonic period (6weeks) Most important time of physical dvlpmt of spinal cord, brain, all internal organs.
- Fetal period
What is spina bifida
a birth defect occurring during the embryonic period when spinal cord and brain don’t develop properly.
What are the substances that can cause birth defect
Teratogens:
Legal drugs: Alcohol (facial malformations), nicotine (miscarriage, still birth, low birth weight, metal retardation, learning difficulties), caffeine;
Recreational drugs:cocaine (seizures), marijuana; Infections: German measles Rubella (deafness), Syphilis;
Env: radiation X-rays, mercury.
What disorder results in abnormality such as small head, malformation of the face and limbs, heart defect, and abnormal brain development?
Fetal alcohol syndrome (FAS)
What are the time range for infancy and childhood?
Infancy (birth to 18-24 months)
Childhood (2 to 11-14 years old)
What happens when infants’ brain are not stimulated enough?
Very few synaptic connections are made. Less capacity to process complex info, solve problem, develop advanced language skills.
What are the inborn reflexes?
rooting reflex
sucking reflex
grasping reflex
How is called the process of developing motor skills as a sequence of steps that usually occur within a predictable range of ages
maturation
What is the dynamic systems theory of development?
children often achieve developmental milestones at different paces, depending on the culture in which they are raised.
What are the senses already operational for the infant’s survival just after birth?
taste (sweet) to make them want to drink nutritious milk;
smell (especially for scents associated with feeding.
Hearing (at 6 months babies hear nearly as well as adults)
What senses are poor in infants?
Vision (see only 8-12 inches from their head and cannot make difference bw colors, prefer high contrast patterns) (like adults at about a year)
Describe Harlow’s finding about attachment
infant rhesus monkey experiment showed that the mother-as-food theory was wrong. comforting touch is critical in the socio-emotional dvlpmt of infants
What is separation anxiety
when an infant are separated from their attachment figures at about 8 months of age. this increases dramatically as the infants approach their first year of life.
What did reveal the Ainsworth’s strange situation test?
3 attachment styles: Secure attachment (get upset when caregiver leaves and seek the caregiver's comfort when he returns; Avoidant attachment (do not cry when caregiver leaves and do not seek comfort when he returns) ; ambivalent attachement : cry a great deal when caregiver leaves but when he returns there is both seek and reject caring contact.
