Developmental Psych Flashcards
What is the synchrony effect?
May & Hasher: The benefit of matching tasks with preferred time of day. Varies with age. Young children & older adults work best in the morning. Age 12 through young adults work best in the evening. Attentional regulation is most impacted by time of day
Erikson’s Psychosocial Stages of Developments (8)
Trust vs. Mistrust (birth to 18 months)
Autonomy vs. Shame (Early childhood- up to 3 years)
Initiative vs. Guilt (Preschool- 3 to 5 years)
Industry vs. Inferiority (School age- 5 to 12)
Ego Identity vs. Role Confusion (Adol- 12 to 18)
Intimacy vs. Isolation (Young adult 18 to 40)
Generativity vs. Stagnation (40 to 65)
Ego Integrity vs. Despair (65+)
2 Kinds of Developmental Change
Qualitative
Quantitative
Qualitative Change
Development is discontinuous, where periods of little change alternate with periods of abrupt, rapid change.
Stage theories assert that difference between developmental stages are characterized by qualitative shifts in thinking rather than simply knowing more
Name 3 Stage Theorists who believe in qualitative developmental change
Piaget
Kohlberg
Erikson
Quantitative Change
Development is continuous, with new abilities & knowledge developing continually over time
Theorist Assoc w/quantitative change
Robbie Case
True of False: Environment affects outcomes more significantly in early years compared to later adulthood.
True
Bronfenbrenner Ecological Approach
5 levels of environmental influence: Microsystem Mesosystem Exosystem Macrosystem Chronosystem
Microsystem
Everyday environment of person (home, school, work, neighborhood)
Mesosystem
Interaction between microsystems
Ex- parent teacher conference; works friends at fall party
Exosystem
Exosystem- Relationship between 2 or more settings, one of which does not directly contain the person
Ex- Elise doesn’t come to work with me, but is work may influence how I parent
Macrosystem
Influence of culture, religion, economy, politics
Chronosystem
Addresses passage of time in a person’s life. Includes expansion of family, moving, changes to larger environment like war
Critical period vs. Sensitive Period
Critical- specific time when something must form or occur, or it will not occur at all; most sensitive to environment or stimulation. Ex: formation of organs during embryonic stage
Sensitive-Stimulation & learning has more of an impact than at other times, but can still develop later at a less optimal time
Klinefelter’s Syndrome
Only in men, extra X chrom- XXY; taller, less intelligent, partial breast dev, small testicles, higher voice, unable to have children
Turner’s Syndrome
Only in women, missing X chrom- XO; normal intellect, no menstruation or ovulation
Down’s Syndrome
Trisomy 21, 3 chrom on chromosome 21; mental retardation, broad skull, slanted eyes, reduced activity
PKU
Autosomal recessive d/o caused by defective gene impacting metabolism-phenylalanine not metabolized properly, can result in severe mental deficiency
Hemophilia
most often in males, sex linked recessive disorder, excessive bleeding, reduced clotting
3 stages of the prenatal period
Germinal
Embryonic
Fetal
Germinal period
Conception to 2 weeks
Zygote rapidly divides and implants onto uterus wall
Embryonic Period
2 weeks to 12 weeks
Dev of major organ systems & structures, incl nervous, respiratory, circulatory, & digestive systems, eyes, ears, limbs,
Most vulnerable to teratogens
Fetal period
8/12 weeks to birth
rapid growth, more complexity to organ systems
nails, lashes develop
charac by cephalocaudal dev
Cephalocaudal Development
Growth proceeds from top of body down
Organizational/activational hypothesis of sex differences
proposes hormones influence sex diffs in 2 phases
1- Early life, males & females exposed to diff levels of hormones that organize nervous system
2- Puberty- males & fem expose to diff levels of sex steroids
Reflexes at birth
Hint: MR Babinski Grasps
Moro
Rooting
Babinski
Grasp
Moro reflex
Startle response, extend legs, arms, fingers, arch back
Rooting
turns head, opens mouth, sucking mvmts in response to touching cheek
Babinski
Spreading toes, twists foot when foot stroked
Infant can perceive color by about ___ months of age
4
Infants achieve 20/20 visual acuity between __ to ___ of age
6 months to 2 years
Binocular vision, for depth percep, develops at ___ of age
4 or 5 months
By __ an infant can distinguish mother’s face from others
1 month
What is cross modal fluency and when does it develop?
Ability to imitate facial expressions; 2 -3 weeks of age
When does a social smile typically emerge?
Around 2 months
Major Motor Milestones & Avg Age
Lifting head- 6 weeks Rolling over- 4 months Sitting alone- 7 months Crawling- 9 months Standing w/support- 9 months Standing alone- 12 months 1st steps- 12 to 15 months Walking up steps- 16 months
5 Stages of Brain Development
- Proliferation (Embryo 2-3 weeks old)
- Migration (Embryo 8 weeks old)
- Differentiation
- Myelination- postnatal
- Synaptogenesis-postnatal
Proliferation
New cells develop in the neural tube
Migration
Immature neurons migrate to specific brain locations, join other neurons to develop brain structures
Differentiation
Neurons take on distinct look, axons & dendrites
Myelination
myelin sheath developed; continues into the 20s, enhancing processing speed, attention span, and frontal lobe fxing
Synaptogenesis
Synapses are formed
True or False: Neurons develop prenatally & postnatally
False: Babies have most of the neurons it will ever have at birth. Neurons grow in size and increase their connections with age & experience
Children can recover language fx up to ___ years of age due to plasticity
7 or 8 years
Brain has lateralized fx, such that handedness are estab by age ___
7 or 8
Hippocampal development is complete by ___, leading to capacity for declarative memory in addition to procedural memory
Middle Childhood
Primary vs. Secondary Aging
Primary- natural upper limit of human lifespan, genetically controlled, daily stressors wear out body’s cells
Secondary-results from disease, disuse, neglect of body
Health Belief Model
perceptions of vulnerability & beliefs about illness influence health bx; health bx result of psychosoc factors, perceived susceptibility to disease, perceived benefits of preventative action vs perceived barriers
What is the most significant, preventable health risk
Smoking
