Test 1 Flashcards
Human Development
the multidisciplinary study of how people change and how they remain the same over time
recurring issues in human development
nature vs nurture, continuity vs discontinuity, universal vs context specific development, biopsychosocial framework, neuroscience
nature vs nurture
the degree to which genetic or hereditary influences (nature) and experimental or environmental influences (nurture) determine the kind of person you are
continuity vs discontinutiy
whether a particular developmental phenomenon represents a smooth progression throughout the lifespan (continuity) or a series of abrupt shifts (discontinuity)
universal vs context specific development
whether there is just one path of development or several paths
biopsychosocial framework
a useful way to organize the biological, psychological, or sociocultural forces of human development
different parts of biopsychosocial framework
biological, psychological, sociocultural, and life cycle forces
biological forces
genetic and health related factors
psychological forces
all internal cognitive, emotional, perceptual, and personality factors
sociocultural forces
interpersonal, societal, cultural, and ethnic factors
life cycle forces
differences in how the same event effects different people
neuroscience
the study of the brain and nervous system, especially in terms of brain-behavior relationships
theory
an organized set of ideas that is designed to explain development
Psychodynamic theories
theories by proposing that development is largely determined by how well people resolve conflicts they face at different ages
psychosocial theory
Erikson’s proposal that personality development is determined by the interaction of an internal maturational plan and external societal demands
epigenetic theory
in Erikson’s theory, the idea that each psychosocial strength has its own period of particular importance
behaviorsm
BF Skinner. Do consequences of behavior determine if behavior is repeated in the future?
reinforcement
a consequence that increases the future likelihood of the behavior that it follows
punishment
a consequence that decreases the likelihood of the behavior it follows
Imitation or observational learning:
learning that occurs by watching how others behave
Self efficacy:
peoples beliefs about their own abilities and talents
Cognitive Developmental theory:
the thought process and construction of knowledge
Piaget’s theory
- sensorimotor stage
- preoperational
- concrete operational
- formal operational
sensorimotor
birth to 2 years. Knowledge based on senses and motor skills
preoperational
2 – 6 years. Symbols as language, only through their perspective
concrete operational
7 years to early adolescence. Understands and applies logical operations to experiences provided they are focused on here and now
formal operational
adolescence +. Thinks abstractly, deals with hypothetical situations, speculates about what may be possible.
information processing theory
proposes human cognition consists of mental hardware and mental software
Vygotsky’s theory:
must consider child’s development against background or environment
Ecological theory:
based on the idea that human development is inseparable from the environmental contexts in which a person develops
Bronfenbrenner’s theory
- microsystem
- mesosystem
- exosystem
- macrosystem
microsystem
the people and objects in an individual’s immediate environment
mesosystem
provides connections across microsystem
exosystem
the social settings a person may not experience first hand but that still influence development
macrosystem
the cultures and subcultures in which the microsystem, mesosystem, and exosystem are embedded
competence
a person’s abilities
enviromental press
the demands put on an individual by the environment
lifespan perspective
human development is multiply determined and cannot be understood within the scope of a single framework
selective optimization with compensation model
the model in which three processes (selection, optimization, and compensation) form a system of behavioral action that generates and regulates development and aging
life course perspective
the ways in which various generations experience the biological, psychological, and sociocultural forces of development in their respective historical contexts
systematic observation
watching people and carefully recording what they do or say
naturalistic observation
people are observed as they behave spontaneously in some real-life situation
structured obseravtions
the researcher creates a setting that is likely to elicit the behavior of interest
self reports
people’s answers to questions about the topic of interest
reliability
the extent to which a measure provides a consistent index of a characteristic
validity
the extent to which a measure actually assess what you think it assess
populations
broad groups od people that are of interest to researchers
sample
a subset of the population
correlational study
an investigation that looks at relations between variables as they exist naturally in the world
correlational coefficient
an expression of the strength and direction of a relation between two variables
experiment
a systemic way of manipulating the key factor or factors that the investigator thinks causes a particular behavior
independent variable
the variable being manipulated
dependent variable
the variable being observed
qualitative research
a method that involves gaining in-depth understanding of human behavior and what governs it
longitudinal study
a research design in which the same individuals are observed or tested repeatedly at different points in their lives
cross sectional study
a study in which developmental differences are identified by testing people of different ages
cohort effects
problems with cross sectional designs in which differences between age groups (cohorts) may result as easily from environmental events as from developmental processes
sequential design
a developmental research design based on cross-sectional and longitudinal designs
chromosomes
threadlike structures in the nuclei of cells that contain genetic material
autosomes
the first 22 pairs of chromosomes
sex chromosomes
the 23rd pair of chromosomes, which determines the sex of the child
DNA
deoxyribonucleic acid, the molecule that composes one chromosome, making it the biochemical basis of heredity
genes
a group of compounds that provides a specific set of biochemical instructions
genotype
the complete set of genes that make up a person’s heredity
phenotype
physical, behavioral, and psychological features that result from the interactions between an individual’s genes and their environment
alleles
variations of genes
homozygous
alleles in a pair of chromosomes that are the same
heterozygous
alleles in a pair of chromosomes that are different
dominant
the allele who’s chemical instructions are followed
recessive
the allele who’s chemical instructions are ignored in the presence of a dominant allele
polygenetic inheritence
phenotypes are the result of the combined activity of many separate genes
monozygotic twins
the result of a single fertilized egg splitting to form two new individuals; also called identical twins
dizygotic twins
the result of two separate eggs fertilized by two sperm; also called fraternal twins
niche picking
the process of deliberately seeking environments that are compatible with one’s genetic makeup
non-shared environmental influences
forces within a family that make siblings different from one another
prenatal development
the many changes that turn a fertilized egg into a newborn human
zygote
a fertilized egg
germ disk
small cluster of cells near the center of the zygote that will eventually develop to form a baby
placenta
a structure thought which nutrients and wastes are exchanged between the pregnant woman and developing child
implantation
the zygote burrows into the uterine wall and establishes connections with a woman’s blood vessels
embryo
the term given to zygote after it is completely implanted into the uterine wall
amnion
the inner sac in which the developing child rests
amnionic fluid
the fluid surrounding the fetus
