Lecture #2: Research Methods & The Study of Sex
Four Ways of Knowing the World:
1. Intuition
Gut feeling, no evidence
2. Logic
Reasoning
3. Authority
Who the information is coming from
4. Observation
Collecting data
Key for scientists
Science is not a “what” to be studied, it is how it is studied. It is necessary for
a scientist to formulate a hypothesis and have a purpose.
Four Canons of Science:
1. Determinism: The universe is orderly; all events have meaningful,
systematic causes
o Theories Causal relationship between variables and their
relationship
o Variables
2. Empiricism: Collecting data or making observations to test hypotheses
3. Parsimony: Explaining observations in the simplest ways possible; in
competing theories, the simpler with the least amount of assumptions is
better
o Also known as Occam’s razor
4. Testability: theories should be testable
o Operational definitions: variables that are well-defined and easily
measured (like time, height and temperature)
Often, variables are not so easy
Some variable are not well defined and can’t be directly observed.
Constructs: Attributes or characteristics that cannot be directly observed
but are useful for explaining behaviour (e.g. intelligence).
o Every measurement can have three types: physiological measures,
behavioural measures and self-reported measures.
The Scientific Method:
TheoryHypothesisResearch Support/Refute
A single study on its own does not tell much, it needs to be replicated:
HOMER
Hypothesize
Operationalize
Measure
Evaluate
Replicate/revise/report
Types of Research:
The types of research vary on the level of control of the variables:
1. Descriptive/Observational:
Involved observing and classifying behaviour
- Marian Keech & “The Seekers”: The Seekers are cult the
believed in aliens called The Guardians, that would save their
group from the apocalypse. The scientists wanted to see their
reactions when The Guardians didn’t show up, and if it would
affect their beliefs. He joined the cult to observe the behaviour
(the group knew he was a scientist). The leader of the cult said
she received a message from The Guardians saying the belief of
the group saved humanity.
Often the first line of research; form the hypothesis after observations
Observational Research:
- Masters & Johnson:
Foundations of sex research
Dispelled misconceptions about sex
Direct observation of sexual activities performed in the
labs
The initial participants of these studies were
prostitutes, but they realized there was a sampling
problem with this
o Later turned to community samples
Based on observations, described a four-stage model of
sexual arousal
o Four-Stage Model of Sexual Arousal:
1. Excitement Phase
2. Plateau Phase
3. Orgasm
4. Resolution Phase
Published a book on homosexuality converted
homosexuals into heterosexuals
o Didn’t say it was a mandatory procedure, yet it
could be done
Huge influence, but much criticism

OneClass has been such a huge help in my studies at UofT especially since I am a transfer student. OneClass is the study buddy I never had before and definitely gives me the extra push to get from a B to an A!

Balancing social life With academics can be difficult, that is why I'm so glad that OneClass is out there where I can find the top notes for all of my classes. Now I can be the all-star student I want to be.

As a college student living on a college budget, I love how easy it is to earn gift cards just by submitting my notes.
