Chapter 2: Theories and Methods of Human Development Flashcards
Theory
an organized set of ideas that helps scientists think about what they observe
Biological perspective
psychological and behavioral development begins with roots in our brain, our genes, and innate instincts
Biological perspective theories
- evolution
- ethological
- epigenetic
Evolutionary theory
all life, and some behaviors, develop and change to adapt to the environment over generations through natural selection
Ethological theory
human behaviors are universal, innate, and gene-based
Epigenetic theory
physical, inborn, genetic characteristics are changed by our environments
Maslow
suggested most people struggle to balance and satisfy needs throughout life; developed a list of what motivates humans
Maslow’s Biological List of Needs from the bottom of the pyramid to the top
- physiological needs
- safety needs
- belongingness and love needs
- esteem needs
- self-actualization
Psychosexual Theory (Freud)
development progresses through five psychosexual stages as unconscious physical urges are mastered
Psychosocial Theory (Erikson)
early experiences and social interaction play a crucial role as people move through eight stages of psychosocial development across the lifespan
Attachment theory (Bowlby; Ainsworth)
close emotional bonds between infants and their caregivers are essential to development
Bowlby
humans have a biological need to be attached and nurtured in early life
Ainsworth
developed and elaborated on the attachment theory
Watson
all babies are born equally capable; children learn everything they know; classical conditioning
Skinner
behavior is more likely to happen with rewards and less likely to occur with punishment; operant conditioning
Social Learning Theory
learning involves thinking and reasoning; the most important part of learning is often other people; social relationships
Bandura
people model behavior and can learn new behaviors through observation and imitation
Cognitive Development Theory (Piaget)
cognitive growth is the result of active world exploration; children’s thinking matures in distinct stages as they actively construct and build what they know
Information processing theory
focuses on the development of thinking and understanding by describing how a person pays attention, remembers, and reacts to the world, similar to how a computer processes information
The cultural perspective (Vygotsky; Rogoff and others)
child learning is based on interactions with other people in a cultural context
Cross-cultural research
focuses on comparing human maturation around the world
Cultural research
identifies variations within communities
Theories of Social Justice
evaluate how social inequality and discrimination affect us and how cultural identity aids in thriving
Scientific Method
multistep process in which scientists evaluate their ideas and find out if they are accurate through collecting and analyzing data
Steps of the scientific method
1- make an observation
2- form a hypothesis
3- collect the data
4- analyze the data
5- share it
Experimental Research
experiment tests the hypothesis that one factor is caused by another
Factors are known as
variables
