different types of influence
heuristic influence, systematic influence
Heuristic influence
When the research generates interest, disbelief (attention)
Systematic influence
When research or theories provide testable predictions
Types of research
Basic, applied, translational
Basic research
No immediate concerns for practical goals
Applied research
Seeking current solutions to practical problems
Translational Research
Mix between applied and basic ( produces results that can be the basis to applied research)
Variable
Something that can have different values
Variables defined by their characteristics
Behavioral, stimulus, and organismic
Behavioral variables
Any observable response of an organism
Stimulus variables
environmental factors that have an effect on organism response
Organismic variables
variable that shows characteristics in an organism
there is 2 types
Observed organismic variables: characteristics we can observe directly (gender)
response-inferred organismic variables: cant observe directly but can observe the existence of it by observable behavior (anxiety)
Variables defined by their use in science
Independent, dependent, extraneous, constant
Independent variables
two types
manipulated
the variables the experimenter can manipulate
non manipulated the characteristics that cant change (iq,age,race)
dependent variables
the response variables from the participants
Extraneous variables
unplanned and uncontrollable variables
Constant
Any event that is prevented from varying (not a variable)
