Module 1 - Research Methods Flashcards
define empiricism
belief that to be deemed true and reliable, knowledge must come from systematic observations that are recorded as data. want to be able to prove that the data is correct
define operational definition
exactly what is meant by each variable in the context of the study, turning abstract ideas into something measurable
define experiment
where all is constant except the variable of interest (independent), which will strategically varies across conditions. dependent variable is what you are measuring from the outcome
define correlational designs
how variables are related to or associated with one another (genre, personality, socioeconomic status). can not determine causality
define experimental designs
can infer causation, all kept constant except variable of interest. rely on random assignment
define reliability
consistency of a measure
test-retest: measurements should be stable across time
interrater: how different experimenters score similar results
define validity
accuracy of measure
internal: is the results from the manipulations, 3rd variables
external: can the results generalize to other groups of people
define structured interview
asking predetermined questions, responses are analyzed and coded
define questionnaires
efficient way to get many response, can use scales and such for responses
define clincical interview
questions can branch off from predetermined questions to follow up on the answers (ex. determining disorders). will give lower internal validity
define naturalistic observations
examining people in their natural environments, researcher has no control of behaviour
define structured observation
people are placed in the same controlled situation while behaviour is recorded, can be used to determine specific factors influencing behaviour
define cross-sectional designs
using different people across different age groups, used for developmental trends, each person is only tested once, no insight into patterns of change within people
define longitudinal designs
look at the changes within the same children over a significant period of development, very rewarding but can be extremely difficult to succeed in completing
define microgenetic designs
track small scale developments in children’s cognitive/behavioural process, multiple observations of same child over a short period of time, detailed look at how specific processes develop
