Research Strategies Flashcards
It refers to the use of objective and replicable methods to gather data for the purpose of testing a theory or hypothesis.
The Scientific Method
Means that everyone who examines the data will come to the same
conclusions, that is, it is not a subjective opinion
Objective
Means that every time the method is used, it results in the same data and
conclusions.
Replicable
Is a set of concepts and propositions intended to describe and explain some aspects of
experience.
Theory
When a measure yields consistent information over time and across
observers.
Reliability
When the instrument measures what it is supposed to measure.
Validity
These include interviews, questionnaires (including
psychological tests), and the clinical method. These instruments differ in the extent to which
the investigator treats individual participants alike.
Interview and Questionnaire ,
Diary method,
Clinical Method
Self report methodologies
It is a method in which the scientist tests hypotheses by
observing people as they engage in everyday activities in their unnatural habitats. In some
cases
Naturalistic Observation
Each participant is exposed to a setting that might cue the behavior in question and is then observed (via hidden camera or one-way mirror) to see
if he or she performs the behavior.
Structured Observations
This is a research method in which the investigator gathers extensive
information about the life of an individual and then tests developmental hypotheses by analyzing the events of the person’s life history. It may also be used to describe groups – group case study.
Case Studies
This is a method in which the research seeks to understand the unique values,
traditions, and social processes of a culture or subculture by living with its members and making
extensive observations and notes.
Ethnography
These are the techniques that measure the relationship
between physiological response and behavior
Psychophysiological Methods
The investigator gathers information to determine whether two or
more variables of interest are meaningfully related.
The Correlational Design
It determines the presence or absence of a relationship
between variables can be determined by examining the data with a statistical
procedure.
Correlational Coeffiecient
It permits a precise assessment of the cause-and-effect relationship
that may exist between two variables. It requires an independent (the predictor) and a dependent
variable (the outcome).
The Experimental Design
