Definition of Psychology: the scientific study of the behavior of individuals and
their mental processes
-We often directly observe behavior and inter-mental processes
Scientific Knowledge vs. Ordinary Knowledge:
o Scientific Knowledge:
Approach: empirical
Observation: systematic, controlled
Concepts: operational specificity
Hypothesis: specific and testable
Measurement: reliable and valid
Attitude: critical and skeptical
Ordinary knowledge:
Approach: intuitive
Observation: casual, uncontrolled
Concepts: ambiguous
Hypothesis: less specific and testable
Measurement: not reliable/ valid
Attitude: accepting
Physical Sciences VS Social Sciences
6 Steps of a research project
1. Ask a question – stems from theory
Theory: attempts to understand precisely why certain events or
processes occur as they do
2. Develop a hypothesis
o Hypothesis: a specific and testable proposition that describes a
relationship between two or more variables (prediction)
3. Select a method and design the study
3. Collecting data – bigger sample = more power = more likely to support
hypothesis
3. Analyze data – draw conclusions – do I have support of hypothesis?
Need to conduct statistical analysis before we draw conclusions;
cant just look at raw numbers – how many people did you talk to, etc?
6. Report findings
Anatomy of a Research Article
o Abstract: summarize what you did in 140 words or less – easiest to write
last
o Introduction: hypothesis is clearly stated at end
Review of research to support hypothesis
, Method: 3 subheadings/sections
Participants: how many, where did they come from, how were they
assigned to conditions, average age, race, gender – only need info that
is relevant to hypothesis
Materials: things used: questionnaires, room set up
Procedure: what did participants do from the time they arrived to
the time they left – don’t go on tangents
Explain questionnaires, etc. in materials section
Results: what were results
Discussion: starts off narrow and then broadens
Were the hypothesis supported or not
Give summary of study – what did you do
Any types of problems or limitations to study
Future research?
Write in past tense
References: APA format
Ethics: discipline dealing with good and evil moral duty
Through research we want to seek information that could be used
for the greater good
However, “evil” can occur → the effect it can have on participants:
psychological harm, physical harm, invasion of privacy
Need to find the balance between the benefits/ good and the harm
Time period and culture changes the standards of ethics
-Milgram:
o Four prompts: the experiment requires that you continue, please continue,
you have no choice, you must go on
Kept going unless the participant refuses after all four
Shows the power of authority
2/3rds of participants gave maximum shock
-Animals in research: up for debate – personal opinion
o About 20 million animals are used in research each year
o 95% of psychological studies using animals use rats, mice, rabbits or birds
o Of all the cats and dogs euthanized each year by researchers and animals
shelters, only 2% of those are euthanized by researchers
-Protecting Participants – minimize harm to participants by:
o IRB: institutional review board – made up of community members and
university members
Have to submit forms with all research plans, forms, scripts, etc.
Board members must approve research as ethically acceptable
before study can be administered
Must consider:
Importance of research vs. potential harm to participants
