Developmental Psychology
Schemas are: mental frameworks to organize and interpret information
Assimilation is: using pre-existing information to interpret new information
Accommodation is: adapting existing schemas to incorporate new information
Stages of cognitive development
Sensorimotor stage (0-2)
Preoperational stage (2-7)
Concrete operational stage (7-12)
Formal operational stage (12+)
The sensorimotor stage is characterized by:
Object permanence: things exist even when not perceived
A not B error: looking for an object where they last found it even if they saw it moved
The preoperational stage is characterized by:
Egocentrism: an ability to view the world only through one POV
Conservation: objects retain their properties despite changes in form
Theory of mind: ability to take another’s perspective
The concrete operational stage is characterized by:
Inductive reasoning: making broad generalizations about specific observations
The formal operational stage includes:
Deductive reasoning: putting together general observations to make specific conclusions
If then thinking: if A occurs then B will happen
Physical development order:
Genome
Zygote
Embryo
Fetus
Tetratogens: harmful chemicals and viruses that can reach the fetus during development
Tetratogens are mostly screened out by the: placenta
Newborn reflexes:
Rooting reflex
Sucking reflex
Moro reflex
Grasp reflex
Stepping reflex
Tonic neck reflex
Rooting reflex is: check stimulus, head orientation, latch
Moro reflex is: startled, arms extended, arms come back in
Stepping reflex is: if held upright, will mimic walking
Tonic neck reflex is: fencing
Habituation: decreased response to familiar stimuli
Visual cliff illusion: depth perception and understanding social emotions
Infantile amnesia: forgetting everything that occurred before 4 years of age
Attachment styles
Secure
Anxious avoidant
Avoidant
Disorganized
Secure attachment is: using the caregiver as a secure base, can explore and come back
Anxious avoidants are: reluctance to explore due to fear of abandonment
Avoidants are: disinterested in the environment and those around them
Disorganized are: wanting love and support but also fear and distrust others, leading to inconsistent behavior
Critical periods are: optimal periods early in life for learning (a time when a person's behavior is especially sensitive to environmental influences)
Delay of gratification (being able to wait for a bigger prize): children able to do this have higher academic success, social success, and lower risk of delinquency
Parenting styles:
Authoritarian
Authoritative
Rejecting-Neglecting
Permissive
Authoritarian parents: are demanding, and unresponsive, use punishment and threats, and give children little autonomy
Authoritative parents: are demanding but warm, responsive, set limits, but give some autonomy
Rejecting Neglecting parents: are disorganized, unresponsive, have no limits, and no consideration for the child’s needs
Permissive parents: are lenient, and responsive, have no limits, and let children act inappropriately
Primary sex characteristics: related to reproductive organs
Secondary sex characteristics: biological consequences of primary sex characteristics
Telomeres: small caps at the ends of DNA that protect them from degradation, they shorten as we age so we slowly lose genetic information
Terminal Decline: we are driven to learn less and spend time fostering connections over time
