◉ What is the scientific method and how is it applied to
psychological research? Answer: The scientific method is the set of
assumptions, rules, and procedures scientists use to conduct
research. In addition to requiring that science is verifiable, the
scientific method demands that procedures are free of personal bias.
◉ What is the definition of a hypothesis? Answer: A specific and
falsifiable prediction about the relationship between two or more
variables.
◉ What is an operational definition? Provide an example. Answer:
An operational definition refers to a precise statement of how a
conceptual variable ( abstract idea that form the basis of research
hypotheses ) which is turned into a measured variable ( varialbes
consisting of numbers that represent the conceptual variables )
(Conceptual Variable) Depression - (operational definition) Number
of negative words used in a creative story; number of appointments
made with a psychotherapist
,◉ Why are ethical guidelines needed within psychological research?
Answer: These are needed with psychological research is the
prevent physical and/or emotional harm to the participants.
◉ What are the various research methods in the field of psychology?
Answer: Descriptive Research
Correlational Research
Experimental Research
◉ What is descriptive research? Answer: research designed to
provide a snapshot of the current state of affairs.
◉ What is Correlational Research Answer: research designed to
discover relationships among variables and to allow the prediction
of future events from present knowledge.
◉ What is Experimental Research Answer: research in which there
is a random assignment of research participants into two groups.
This is followed by a manipulation of a given experience for one
group while the other is not manipulated. One group is the
experimental group that receives the manipulation. The other group
is the control group that does not. The two groups are then
compared to determine the influence of the manipulation.
,◉ What is the relationship between a population and a sample?
Answer: The people chosen to participate in the research, called a
sample, are selected to be representative of all the people that the
researcher wishes to know about, called the population. "Sampling
is the process of selecting a representative group from the
population under study. The target population is the total group of
individuals from which the sample might be drawn. A sample is the
group of people who take part in the investigation. The people who
take part are referred to as "participants"."
◉ Independent Variable Answer: The variable in an experiment that
is manipulated or compared
◉ Dependent Variable Answer: The variable in an experiment that is
measured; the outcome of an experiment
◉ Control Group Answer: The group of subjects in an experiment
that does not receive the independent variable
◉ Experimental Group Answer: EXPERIMENTAL GROUP is the group
receiving the independent variable
◉ What does a correlational research design examine? Provide an
example. Answer: research designed to discover relationships
among variables and to allow the prediction of future events from
present knowledge.
, ◉ Describe examples of a positive and a negative correlation.
Answer: Correlational-To assess the relationships between and
among two or more variables.
Postiive - As children age they get better at math
Negative - Age of a child and the number of diapers they use
"Negative correlation, the variables move in inverse, or opposite,
directions. As one variable increases, the other variable decreases.
For example, there is a negative correlation between self-esteem and
depression. Positive correlation is when there is an increase in one
variable it is associated with an increase in another variable. For
example: with height and weight, taller people tend to be heavier."
◉ What are the differences in interpretations of correlational and
experimental designs? Answer: In correlational studies a researcher
looks for associations among naturally occurring variables, whereas
in experimental studies the researcher introduces a change and then
monitors its effects.
"An experiment isolates and manipulates the independent variable
to observe its effect on the dependent variable, and controls the
environment in order that extraneous variables may be eliminated.
Experiments establish cause and effect. A correlation identifies
variables and looks for a relationship between them."
◉ What are the four parts of a neuron and its role in neural
communication? Answer: Cell Body (Soma), Dendrites, Axon, Myelin
Sheath
