Final Exam Flashcards
Nature-Nurture Issue
The debate over the relative importance of biological predispositions (nature) and environmental influences (nurture) as determinants of human development.
Activity-Passivity Issue
The issue in develop- mental theory centering on whether humans are active contributors to their own development or are passively shaped by forces beyond their control.
Continuity-Discontinuty Issue
The debate among theorists about whether human development is best characterized as gradual and continuous or abrupt and stagelike.
Universality-Context-Speficity Issue
The de-bate over the extent to which developmental changes are common to everyone (universal, as in most stage theories) or different from person to person (particularistic).
Assumptions on the Lifespan Perspective
- lifelong
- multidirectional
- highly plastic (flexible in response to outside influence)
- involves gains and losses
- influenced by biological, historical, and cultural forces
Correlational Method
A research technique that involves determining whether two or more variables are related. It cannot indicate that one thing caused another, but it can suggest that a causal relationship exists or allow us to predict one characteristic from our knowledge of another.
Experimental Design
The holding of all other factors besides the independent variable in an experiment constant so that any changes in the dependent variable can be said to be caused by the manipulation of the independent variable
Cross-Sectional Design
A developmental research design in which different age groups are studied at the same point and compared.
Sequential Design
A developmental research design that combines the cross-sectional approach and the longitudinal approach in a single study to compensate for the weaknesses of each.
Longitudinal Design
A developmental research design in which one group of subjects is studied repeatedly over months or years.
Id
A psychoanalytic term for the inborn component of the personality that is driven by the instincts or selfish urges.
Ego
Psychoanalytic term for the rational component of the personality.
Superego
The psychoanalytic term for the component of the personality that consists of the individual’s internalized moral standards.
Neutral Stimulus
A stimulus that does not naturally elicit response of interest before conditioning.
Unconditioned Stimulus
A stimulus that elicits a particular response without prior learning.
Unconditioned Response
The unlearned response elicited by an unconditioned stimulus.
Conditioned Stimulus
An initially neutral stimulus that elicits a particular response after it is paired with an unconditioned stimulus that always elicits the response.
Conditioned Response
A learned response to a stimulus that was not originally capable of producing the response.
Reinforcement
Pleasant consequence that decreases the probability of a behavior.
Operant Conditioning
Also called instrumental
conditioning, a form of learning in which freely
emitted acts (or operants) become more or less
probable depending on the consequences they
produce.
Positive Reinforcement
The process in operant
conditioning whereby a response is strengthened
when its consequence is a pleasant event.
Negative Reinforcement
The process in operant
conditioning in which a response is strengthened
or made more probable when its consequence
is the removal of an un pleasant stimulus
from the situation.
Punishment
Unpleasant consequence that decreases the probability of a behavior
Positive Punishment
The process in operant
conditioning whereby a response is weakened
when its consequence is an unpleasant event.
Negative Punishment
The process in operant
conditioning in which a response is weakened
or made less probable when its consequence is
the removal of a pleasant stimulus from the
situation.
Constructivism
The position taken by Piaget and others that humans actively create their own understandings of the world from their experiences, as opposed to being born with innate ideas or being programmed by the environment.
Epigenetic Psychbiological Systems Perspective
Gilbert Gottlieb’s view that development is the product of interacting biological and environmental forces that form a larger, dynamic system, both over the course of evolution and during the individual’s life.
Psychoanalytic Theory
The theoretical perspective associated with Freud and his followers that emphasizes unconscious motivations for behavior, conflicts within the personality, and stages of psychosexual development.
Genes
A functional unit of heredity made up of DNA and transmitted from generation to generation.
How do genes affect physical and psychological development?
Contribute directly to physical traits, but only indirectly to psychological traits.
Dominant Genes
A relatively powerful gene that is expressed phenotypically and masks the effect of a less powerful recessive gene.
Recessive Genes
A less powerful gene that is not expressed phenotypically when paired with a dominant gene.
How do you do a Punnett Square?
A a -------------------- A | AA | Aa | |---------------| a | Aa | aa | ---------------------
Heritability
The amount of variability in a population on some trait dimension that is attributable to genetic differences among those individuals.
Effects of shared and non-shared environment on trait expression:
Shared: common experiences = increased similarity
Non-Shared: unique experiences = increased differences
Passive Gene-Environment Correlation
Type of environment provided by parents.
Evocative Gene-Environment Correlation
Types of reactions a person’s behavior triggers in others.
Active Gene-Environment Correlation
Types of environments we actively seek out.
Germinal Period
First phase of prenatal development, lasting about 2 weeks from conception
until the developing organism becomes
attached to the wall of the uterus.
Embryonic Period
Second phase of prenatal
development, lasting from the third through the
eighth prenatal week, during which the major
organs and anatomical structures begin to
develop.
Fetal Period
The third phase of prenatal development, lasting from the ninth prenatal week
until birth; during this period, the major organ
systems begin to function effectively and the fetus grows rapidly.
1st Trimester
External genitals form. Reflexive breathing.
2nd Trimester
Myelin production, refined movements, sensory organs.
3rd Trimester
Rapid weight gain, distinguishes tone and rhythm.
Teratogens
Any disease, drug, or other environmental agent that can harm a developing fetus.
What factors influence the severity of teratogen effects?
- Critical Period: most harm during rapid organ development
- Dosage/Duration: larger doses = longer exposure = more harmful
- Heredity: some are better able to withstand harmful environments
Fetal Alcohol Syndrome
A group of
symptoms commonly observed in the offspring
of mothers who use alcohol heavily during pregnancy,
including a small head, widely spaced
eyes, and mental retardation.
Consequences of illegal drugs during pregnancy:
prematurity, low birth weight, physical defects, drug addiction, neonatal death, decreased availability of oxygen to fetus
Secular Trends
A trend in industrialized society toward earlier maturation and greater body size.
Brain Laterality
The specialization of the two hemispheres of the cerebral cortex of the brain.
Cephalocaudal Development
The principle that growth proceeds from the head (cephalic region) to the tail (caudal region).
Osteoarthritis
A joint problem among older adults resulting from a gradual deterioration of the cartilage that cushions the bones and keeps them from rubbing together.
Reserve Capacity
The ability of many organ systems to respond to demands for extraordinary output, such as when the heart and lungs work at maximal capacity.
Physical Fitness in childhood:
- 60 minutes moderate activity
- promotes physical, cognitive, social well-being
Physical Fitness in adolescence:
approaching peak of fitness and health
Physical Fitness in old age:
- activity throughout lifespan = lifelong benefits
- improved cardio
- slows bone loss
- strengthens muscles
- less depression
- delays disability
Sensation
The process by which information is detected by the sensory receptors and transmit- ted to the brain; the starting point in perception.
Perception
The interpretation of sensory input. Influenced by past experiences.
Nativism
Perception is a product of innate capabilities (nature).
Constructivism
Perception is the result of interpretation & learning (nurture).
Depth Perception
Ability to judge the distance of objects from one another and ourselves. Important for guiding motor activity.
Visual Cliff Research
An elevated glass platform that creates an illusion of depth and is used to test the depth perception of infants.
Depth is perceived ~2 months of age, but not feared. Feared crawlers will not cross. Increased heart rate.
- Most babies cross shallow side (but not deep) to get to mom.
- Fear of drop-off related to crawling
Phonemes
Basic speech sounds
Speech Perception in 1st week of life:
Can distinguish vowel sounds and common vs. uncommon sounds.
Speech Perception 2-3 months old:
Can distinguish similar consonant sounds.
Speech Perception in 1 year olds:
Largely insensitive to sounds not part of their native language.
Changes in smell across lifespan:
- well developed at birth
- increased thresholds over age 70
Changes in touch across lifespan:
- present before birth
- decreased sensitivity in old age
Changes in taste across lifespan:
- new acquired tastes in adolescence
- increased thresholds over age 70
Changes in vision across lifespan:
- 90% of adults wear corrective lenses by age 70
