Importance of studying child development
Early experience shape later experiences
Domains of Development
Physical, Cognitive, and Social-Emotional
Physical domain of development
Biological changes, integration of sensory and motor information
Cognitive domain of development
Thinking, understanding, reasoning
Social-Emotional domain of development
Connections/Emotions
Nature v. Nurture-what is nature
Genetic make-up, biological
Nature v. Nurture-what is nurture
Environment
David Reimer
His circumcision was botched, parents decided to cut off his penis and raise him as a girl. He always felt different and ended up killing himself. Genetic make-up had a bigger influence than his environment.
Developmental Psychopathology
Distortions of normal development result in a disorder. Needs to be an understanding of what is "normal development."
Equifinality
Multiple pathways leading to one outcome.
Multifinality
One pathway with multiple outcomes.
Research aims to...
Generalize findings
Individuals are defined by their....
risk and protective factors
Risk Factors
Increase likelihood of outcome
Protective Factors
Decrease likelihood of outcome
Active niche picking child's role
Seeking compatible and stimulating environments.
Types of Research
Basic and Applied
Basic Research
Adds to understanding of development, refines theories
Applied Research
Makes immediate changes to life
Hypothesis
Prediction based of theoretical ideas or observations
Scientific Method
Process of forming and testing a hypothesis
Operationalization
Ability to measure a concept
Interrater reliability
Reliability between experimenters.
Internal Consistency
Reliability between separate test items.
Validity
A test measures what it ought to
Face Validity
Appearing to measure what it ought to
External Validity
To what degree can findings be generalized
Internal Valididty
Cause and effect determined
Generalizability
The ability to expand the results to a population
Population
Everyone in the category being studied
Sample
Reflects the population
Norm
The average/typical performance of an age group
Performance Tests
Requires child to do something
Achievement Standardized Test
Academic skills
Ability Standardized Test
Intellect
Personality Standardized Test
Evaluates thoughts, emotions etc...
Projective Standardized Test
Interpretation of ambiguous stimuli (Ink blot tests)
Neuropsychosocial Standardized Test
Asses functioning to identify problems or disorders
EEG
Electroensephalogram measures electrical activity
ERP
Event-related potential electrical response to stimuli
MRI
Picture of brain structures
fMRI
Functional MRI tracks blood flow in brain
Archival Records
Data collected by others
Case Studies
Comprehensive review of a single case
Experimental Group
Receives the IV
Control Group
Baseline
Random Assignment
Ensures generalizability/reliability
Independent Variable
What is changed
Dependent Variable
What is measured
Quasi Experiment
Natural occurring phenomenon, control everything but group assignment. Ex. spanking
Correlation
Relationship, does not mean causation
Longitudinal Research
Follows one group over time
Attrition
Loss of participants
Sample Bias
Less representative
Cross-Sectional Research
Multiple age groups, one measurement at a time
Cohort Effect
Differences between groups
Cross-Sequential
Longitudinal and Cross sectional, multiple age groups, measure over time
Meta-Analysis
Combines data from different sides
Folk Wisdom
Widely accepted facts without scientific support
Intervention
Treatment of an identified problem
Theory
Basic principles, organize observations, help us understand and predict
Developmental Theories
How change happens (qualitative/quantitative), why change happens/or stays constant
Psychoanalytic Theory
Freud, conscious v. unconscious mind
Id
Basic Drives
Ego
Real world
Superego
Conscience
Oral Psychoanalytic Theory Stage
Birth-18 months, mouth
Anal Psychoanalytic Theory Stage
18 months-3 years, anus
Phallic Psychoanalytic Theory Stage
3-6 years, Oedipus Complex, Electra Complex
Latency Psychoanalytic Theory Stage
6-12 years, sex drive disappears
Genital Psychoanalytic Theory Stage
12+ years, genitals, sexual interest in peers emerges
Erik Erikson
Focused on the ego (identity), psychosocial stages
Behaviorism
Focus on observable behavior, response to external stimuli, environment shapes personality
Tabula Rasa
Kids are a blank slate
Classical Conditioning
Pairing together two stimuli to provoke a response
Operant Conditioning
Positive Response reinforce our behavior
Scheduled Reinforcement
Determinant of when a reinforcement was given
Interval Schedule
Reinforcement is given after a period of time
Ratio
Reinforcement given after a number of behaviors
Fixed Interval
Reinforcement given after fixed periods of time
Variable
Reinforcement given after different periods of time
