Unit Four (Psychological Development) Flashcards
Interaction
Both nature and nurture work together
Prenatal Period
Nine months between conception and birth
Zygotes
The fertilized egg – experiences rapid cell division in the first 2 weeks
Zygote-Fetus
Zygote-first 10 days
Embryo: from 10 days after fertilization through 2nd month
Fetus: 9 weeks after fertilization till birth
Teratogens
Harmful chemicals/viruses that can harm the unborn child (smoking, alcohol, other drugs)
Fetal Alcohol Syndrome
Mental/physical problems due to a pregnant woman’s heavy drinking
Rooting
(Sucking reflex) an instinctive feeding reflex
Moro
When startled, the baby will throw its arms and legs out, and retract them making itself as small as possible
Babinski
When a baby’s foot is stroked its toes will spread out
Myelinate
A part of motor development when your neurons begin to connect and develop their myelin coating
Synaptic Pruning
Unused neural connections are destroyed but the neurons are left for later use
Synchronicity
Babies and mothers smile, vocalize, touch together-not a disjointed action
Imprinting
Forming a rigid attachment based on instincts
Secure Attachment
Most common, feel close to their mothers, more willing to explore and tolerate new situations
Insecure Attachment
Do not like to explore new experiences-feel stressed out or avoid the experience
Anxious Ambivalent Attachment
Extreme stress when parents leave, but hard to console even when parents return
Avoidant Attachment
Resist being held when new experiences are presented, do not return to parent after an absence
Contact Comfort
Stimulation and reassurance derived from physical touch
Psychosocial Dwarfism
A growth disorder caused by emotional neglect, abuse, or stress, leads to stunted growth and cognition
Responsive Parenting
Sensitive parents lead to a more secure attachment
Maturation
Internally programmed growth of a child
Mat. Readiness
When a child is ready to be pushed to learn (walking)
Infantile Amnesia
Memory is not fully developed-before three years of age, we remember very little
Schemas
Mental structures or programs that guide a child’s thought processes
