final exam cumulative Flashcards
Independent variable
the constant variable that determines the outcome of the dependant variable
dependent variable
the variable that relies on the independent variable for the outcome
control
does not receive any treatment to provide a baseline for the rest of the experiment
random assignment
people must be chosen at random to receive valid results for the experiments
informed consent
people must give written consent for an experiment after being informed of all that it consists of. they can withdraw their consent at any time. deception is only allowed in certain situations
correlation studies
only provide proof of a relationship and tell how strong of a relationship. not cause and effect
strong vs weak correlation
a strong correlation is close to 1 or -1 and means there is a relationship
a weak correlation is close to 0 and means little to no relationship
positive vs negative correlation
positive means the variables move in the same direction together
negative means the variables move in opposite directions
has nothing to do with the strength of the relationship
experimental studies
find cause and effect between variables
frued’s theory
psychodynamic theory- the unconscious mind strongly effects the conscious thought process
id, ego, superego
id- raw unconscious drives
ego- mediates the two
superego- rule following conscious
Piaget’s theory
children develop shortcuts to mental processes called schemata. at they grow, their schemata adjusts by accommodation and assimilation. this is where they connect a new experience to what they already know and develop knew schemata based on this connection.
Piaget’s stages
sensorimotor, preoperational, concrete operational, formal operational
sensorimotor stage
age 0-1, experiencing the world through senses and actions
preoperational stage
age 2-6, experiencing the world through words and images but lacking logical reasoning and thought
concrete operational stage
age 7-11, concrete mental processes, analogies, and logic as well as arithmetic sequences
formal operational stage
age 12, understanding higher-level thinking and reasoning
classical conditioning
conditioning a natural reflex to be triggered by an unnatural stimulus through simultaneous stimulation from the natural stimulus and the conditioned stimulus
operant conditioning
using reinforcement and punishment to achieve desired behavior
positive and negative reinforcement
positive- adding something good to increase behavior
negative- taking away something bad to increase behavior
positive and negative punishment
positive- adding something bad to decrease a behavior
negative- taking away something good to decrease a behavior
reinforcement schedule types
fixed ratio, variable ratio, fixed interval, variable interval
fixed ratio
after a certain number of responses reinforcement is given
variable ratio
after an unpredictable number of responses reinforcement is given
