Cards

Term
Developmental Psychologists
Definition
Study the sequence of physical & psychological changes that humans undergo as we grow older
Term
Three Perspectives
Definition
1. Stability vs. Change
2. Continuity versus discontinuity
3. Nature versus nurture
Term
What is: 1. Stability versus change
Definition
Simply put, we can ask whether development is best characterized by stability (for example, does a behaviour or trait such as shyness stay stable in its expression over time?) or change (could a person's degree of shyness fluctuate across the life span?).
Term
What is: 2. Continuity versus discontinuity
Definition
In a continuous process development is conceived of as a process of gradual accumulation of a behaviour, skill, or knowledge where discontinuity suggest that behaviours or skills often change qualitatively across time, and that new organizations of behaviours, skills, or knowledge emerge in a rather abrupt or discrete fashion.
Term
What is: 3. Nature vs. Nurture
Definition
Nature suggests that genetic factors determine our outcome where nurture states that environment is primarily responsible for development.
Term
Methods for studying development
Definition
1. Cross-sectional
2. Longitudinal
3. Sequential
Term
Method 1: Cross Sectional
Definition
A cross-sectional study is a research method where data are collected at the SAME TIME from people in different age categories.
Term
Method 2: Longitudinal
Definition
Where the same group of subjects is studied OVER TIME.
Term
method 3: Sequential
Definition
Combination of both longitudinal and cross sectional studies. The idea of it is to shorten the length of the research and decrease the number of developmental suppositions.
Term
Stages of Prenatal Development
Definition
1. Germinal
2. Embryonic
3. Fetal
Term
Prenatal Stage 1: Germinal
Definition
Stage that begins at conception and lasts through the second week. During this time, the fertilized egg (now called a zygote, and consists of a single cell) makes it way down the fallopian tube, and begins to have cell reproduction.
Term
Prenatal Stage 2: Embryonic Stage
Definition
The embryonic stage begins after implantation and lasts until eight weeks after conception.Soon after implantation, the cells continue to rapidly divide and clusters of cells begin to take on different functions (called differentiation).
Term
Prenatal Stage 3: Fetal Stage
Definition
From 8 weeks to 38 weeks. Although all of the organ systems were formed during embryonic development, they continue to develop and grow during the fetal stage until it becomes full term.
Term
Birth Defects
Definition
Recessive gene disorders:
Tay-Sachs disease, cystic fibrosis, phenylketonuria (PKU)
Chromosomal Abnormalities:
Downs syndrome, Patau’s syndrome, and Edward’s syndrome
Term
Tay-Sachs disease
Definition
an inherited disease of infancy characterized by profound mental retardation and early death; it is caused by a recessive gene mutation.
Term
cystic fibrosis
Definition
the most common congenital disease; the child's lungs and intestines and pancreas become clogged with thick mucus; caused by defect in a single gene; no cure is known
Term
phenylketonuria (PKU)
Definition
a genetic disorder of metabolism; lack of the enzyme needed to turn phenylalanine into tyrosine results in an accumulation of phenylalanine in the body fluids which causes various degrees of mental deficiency
Term
Downs syndrome
Definition
a congenital disorder caused by having an extra 21st chromosome; results in a flat face and short stature and mental retardation
Term
Patau’s syndrome
Definition
The extra chromosome 13 disrupts the normal course of development, causing heart and kidney defects.
Term
Edward’s syndrome
Definition
Caused by the presence of three – as opposed to two – copies of chromosome 18 in a fetus or infant's cells. The incidence of the syndrome is estimated as one in 3,000 live births. The incidence increases as the mother's age increases. The syndrome has a very low rate of survival, resulting from heart abnormalities, kidney malformations, and other internal organ disorders.
Term
Teratogens
Definition
any agent that interferes with normal embryonic development. (Alchohol, narcotics, nicotine, cocain, lead)
Term
Maternal Health
Definition
Health of the mother resulting from AIDS, Malnutrition, Stress, Low Birth Weight
Term
Gestational Length
Definition
Full-Term infant - 37-39 weeks
Pre-term Infant -Before 37-39 Weeks
Post-term Infant - after 42 weeks
Term
Newborn Sensations
Definition
Vision, Hearing, Taste, Smell, Pain
Term
Rooting reflex
Definition
consisting of head-turning and sucking movements elicited in a normal infant by gently stroking the side of the mouth or cheek
Term
Other Reflexes
Definition
Sucking - Natural ability to suck
Grasping - Ability to grip your finger
Term
Moro Reflex
Definition
a normal reflex of young infants; a sudden loud noise causes the child to stretch out the arms and flex the legs
Term
Babinksi Reflex
Definition
Extension upward of the toes when the sole of the foot is stroked firmly on the outer side from the heel to the front
Term
Maturity
Definition
Any relatively permanent change in thought or behavior that occurs as a result of internal aging, without experience, and no influence
Term
Gender Differences: Middle childhood
Definition
Girls more physically mature & superior in skills requiring flexibility, agility, & balance
Boys superior in physical skills
Requiring strength & gross motor abilities
Term
Gender differences: Early Adolescence
Definition
Boys excel on most measures of motor ability
Term
Adolescence:
Definition
Girls: 11-12
Boys: 13-14
Term
Jean Piaget (1896-1980) - Schema
Definition
Altering of perceptual experiences by taking in new information and adding it to our understanding.
Term
Assimilation
Definition
The process of taking in new information into our previously existing schema’s is known as assimilation.
Term
Accomodation
Definition
adaptation involves changing or altering our existing schemas in light of new information, a process known as accommodation
Term
Piagets stages of cognitive development
Definition
Sensorimotor stage (birth - 2 yrs)
Preoperational stage (2yrs - 7 yrs)
Concrete-Operational Stage (7-12yrs)
Formal-Operational Stage (12-Adulthood)
Term
Sensorimotor Stage
Definition
Development of Object Permanence
1mos - Learn to work body
1-4mos - Start Following objects
4-10mos - Reach for objects in sight
10-12mos - Reach for hidden items
12-18mos - Find hidden items
18-24mos - Discovery of new means
Term
Preoperational stage
Definition
Language & Symbolic Representation
Egocentric
Judgments based on appearance not logic
Concept of Conservation
Beyond their grasp
Term
Preoperational stage
Definition
Language & Symbolic Representation
- Cannot control logical language
Egocentric
- Cannot see others point of view
Judgments based on appearance not logic
Concept of Conservation
- Can't differentiate amounts (fluid experiment)
Term
Formal-Operational Stage
Definition
During this time, people develop the ability to think about abstract concepts.
Term
Concrete-Operational
Definition
During this time, children gain a better understanding of mental operations. Children begin thinking logically about concrete events, but have difficulty understanding abstract or hypothetical concepts.
Term
Cognitive disequilibrium
Definition
Disturbance in what they know and what they just learned.
Term
Critique of Piaget
Definition
Research methods - small sample
Other factors like environment
Underestimates childrens abilities
