2Scientific Methods
- Scientific methods unify the discipline of
psychology - A basic goal in science is _____________________
- An approach to information that involves
- challenging assumptions
- __________________________
- a reliance on _________________
- a careful scrutiny of the methods used to derive
evidence
3The Science of Psychology The Scientific Method
4Main Goals in Research
- ______________a phenomenon.
- Make _________________ about the phenomenon.
- ________________ the phenomenon to ask specific
questions about it. - _________________the phenomenon.
5The Research Process
- The first step is to develop a _________________.
- An organized set of principles that describes,
predicts, and explains some phenomenon. - The second step is to form a __________________.
- A specific testable prediction, often derived
from a theory that provides ______________________
________. - An operational definition defines a research
variable in terms of the procedures needed to
control and measure it.
6 The Research Process
7The Science of Psychology Research Methods
- Four key research methods
- ____________________
- Correlational
- ___________________
- Biological
8Research Settings
- _______________________
- Regulated environment
- Participants can be carefully observed.
- _____________________
- Conducted in real-world locations.
9The Science of Psychology Research
MethodsDescriptive Research
- 1. _____________
- Research observes and records behavior without
producing causal explanations
10The Science of Psychology Research
MethodsDescriptive Research
-
- Three types of descriptive research
- Naturalistic Observation
- __________________
- Case Study
Art of Prediction
11Naturalistic ObservationWatching Behavior
- Features
- Observe behavior in the environment in which it
typically occurs - Strengths
- Provides uncontaminated (?) descriptive data
about behavior - Pitfalls
- __________________________
- ____________________________
12Case Studies Taking a Closer Look
- Features
- Intensive examination of a specific person or
situation - Strengths
- Provides detailed descriptive analysis of new,
complex, or rare phenomena - Pitfalls
- May not provide ____________________ picture of
phenomena
13Psychological Measurements
- ______________________
- Method of observation
- Asks people to describe thoughts, feelings,
behavior - ______________________
- Firsthand observation of participants behaviors
- _______________________
- Based on past records
14The Science of Psychology Research
MethodsCorrelational Research
- 2. Correlational Research scientific study in
which the researcher observes or measures
(without directly manipulating) two or more
variables to find _________________ between them
Art of Prediction
15Research Designs
- _______________________
- A statistical measure of how closely two
variables are associated/related. - A correlation can range from -1.0 to 1.0.
- 1.0 (or -1.0) is a __________________________
16Correlational Studies Looking For Relationships
- Features
- __________________________________
- Strengths
- Test predictions, evaluate theories, suggest new
hypotheses - Pitfalls
- Cannot confirm causal relationships
17The Science of Psychology Research
MethodsCorrelational Research
- _______________Correlation two variables move
(or vary) in the same directioneither up or down
18The Science of Psychology Research
MethodsCorrelational Research
- ______________Correlation two variables move
(or vary) in the opposite directioneither up or
down
19The Science of Psychology Research
MethodsCorrelational Research
- _________________ no relationship between two
variables (when one variable increases, the other
can increase, decrease, or stay the same)

21The Science of Psychology Research
MethodsCorrelational Research
- Can you see why correlation can never show cause
and effect?
22The Science of Psychology Four MajorResearch
Methods (Continued)
- 3. _______________________ carefully controlled
scientific procedure that manipulates variables
to determine cause and effect
23Experiments
- A research method in which the investigator
varies some factors, keeps others constant, and
measures the effects on __________________________
_____.
24Experiments Exploring Cause and Effect
- Features
- Manipulation of an ________________ to see its
effects on a ____________________. - Strengths
- Can establish a cause-effect relationship
- Pitfalls
- _______________________
25Experiments
- ______________________
- Any variable that the researcher manipulates in
an experiment. - The proposed _____________________ in the
dependent variable. - ________________________
- A variable that is being measured in an
experiment. - Proposed to be affected by the independent
variable.

27The Science of Psychology Research
MethodsBiological Research
- 4. Biological Research scientific study of the
brain and other parts of the nervous system
28The Science of Psychology Four Key Research
Methods
29Selecting Human Participants for Research
- To whom can the results be generalized?
- Importance of sampling
- How can one select a representative sample?
- Random vs. biased samples
- Convenience samples
30Ethical Guidelines for Psychologists
- Do psychologists deceive people when they do
research?
31Ethical Guidelines for Psychologists
- All research guided by ethical standards
- Applies to both human and animal research
- Role of the Institutional Review Board
(____________) - APAs Ethical Principles of Psychologists and
Code of Conduct.
32The Science of Psychology Ethical Guidelines
- Human research participants need
- _____________________
- Voluntary participation
- Restricted use of deception
- __________________
- ______________________
- Alternative activities
33Ethics
- Informed Consent
- The ethical requirement that prospective
participants receive enough information to decide
freely whether to participate in a study - ________________________________, and one must be
free to withdraw at any time.
34Ethics Considerations in Human Research
- ______________________
- A research procedure used to mislead participants
about the true purpose of the study - If deception is used, debriefing is necessary.
35The Science of Psychology Ethical Guidelines
(Continued)
- Advocates believe nonhuman research offers
significant scientific benefits. Opponents
question these benefits and suggest nonhuman
animals cannot give _________________________ - Psychologists must maintain high standards for
both human and nonhuman animal research.
36Ethics Considerations in Animal Research
- Animal Welfare
- ______________________________ and humane
treatment are universally supported. - Allegations of mistreatment in laboratories are
rarely supported by facts. - Animal Rights
- There is _________________ over whether animals
have similar rights as humans.
