Human Development Exam 1 Flashcards
Sensitive Period
susceptible to environmental experiences
Critical Period
When an event has greatest consequence. Must happen in a window of time.
Plasticity
Degree to which development can be influenced by environment
Performationism
children are like minature adults
Tabula Rasa
- John Locke
- Children, clean slate.
- innately good
Continuous
- gradual process. Builds on itselv
- Quantitative
Discontinuous
- Abrupt.
- Does not build
- Qualitative
Testable prediction about 2 or more variables
Hypothesis
Observation & Experimentation that produces reliable results
- Scientific Method
- Question
- Hypothesis
- Testing
- Collect Data
- Draw conclusion
Systemic People watching
-
Naturalistic Observation
- can’t establish ause an effect because no control
Detailed examination of the life of one person
Case Study
Statistical relationship between 2 variables. Knowing one makes possible to predict the other
Correlational study
An experimental group and a control group
Experiment
Variable is different for the experimental group than for the control Group
Independent Variable
outcome can be measured to calculate the results of the experiment by comparing the ex group with the control group
Dependent Variable
Collecting data of a variety of ages on a single occasion
Cross Sectional Research
Same persons are followed over time and data collected on 2 or more occasions
Longitudinal Research
An explanation of historical experience rather than maturation.
Cohort Effect ex. 911 or Katrina
Unconscious biological focus. Freud
Psychoanalytic
Theory that behavior results from our experiences and what receive from external environment
Behaviorism
Looking to the caregiver for cues
Social Referencing
For all age groups a process that exists for cognitive functioning
Information Processing
Cognitive Development
how cognition changes with Age. Piaget.
Social and cultural factors
sociocultural
Ecological Systems
- shaped by 5 interrelated systems in the social environment.
- Too broad
Pros for longitudinal Research
can follow one age group over time and get a consistant study
Cons for Longitudinal Research x6
- Cost
- Time
- Attrition
- Practice
- Measurement change
- Less of an impact over time
Pros for Cross sectional research
- Fast, easy cheap
Cons for Cross Sectional Research
- Measures developmental differences not developmental change.
- Cohort differences
Cons with Correlational Research
- statistical relationships can be interpreted in terms of changes in one variable causing changes in the other
- Directionality Problem
- what if third variable effects both
Cons with Lab testing
- Ethical Dilemma
- Artifical context
Problems with Clinical Interview
relies on verbal expression. Difficult to compare between other individuals.
Problems with Psycho-biological
- Information you cannot observe
- expensive
- invasive
Problems with case study
Can’t generalize. Tend to make assumption about everyone
Problems with Naturalistic Observation
difficult to be objective. Observer can affect situation they are observing
Problems with Self Report
Selective Memory, inaccurate
Normal cell division, exact mutation always happens
mitosis
Contain Gametes. 23 from Mom 23 from Dad.
Meiosis
When the union of sperm and ovum and new cell occurs
zygote
Fraternal twins
dizygotic
100% genetic material. Identical Twins
Monozygotic
double stranded make up of chromosomes
DNA
Store and transport genetic information. In nucleus of cells contains genes.
Chromosomes
Contain Instructions, Proteins, Segment DNA
GENE
X & Y Chromosomes. X is longer with more genetic material
Sex Chromosomes
Unique Genetic Inheritance
Genotype
Actual characteristics derived from genotype
phenotype
2 Dominant 2 Recessive
homozygous
1 dominant 1 recessive
Heterozygous
When the dominant gene gets expressed
Dominant Inheritance
When recessive gene is influential
Recessive Inheritance
Many genes determine a characteristic
Polygenic Inheritance
Gene Therapy
Method of treating genetic disorders by replacing affected genes
