History of Psychology
Wilhelm Wundt is given the honour of formally founding experimental psychology.
There is a tiny delay in the perception of the thought meter (can’t listen and look at the pendulum
where it struck the bell at the same time)
Edward Titchener was a student of Wundt’s who also believed psychologists should study consciousness
by describing it.
Darwin’s Theory of Psychology- led into the development of functionalism and behaviourism
Functionalists- wanted to understand the function of the mind, both mental processes and behaviour
are worth to study.
Science depends on HOW one studies a subject, not on the subject itself.
1. Determinism: The universe is orderly- all events have meaningful, systematic causes
Theories: statements about the casual relation between two or more variables.
2. Empiricism : The best way of figuring out these orderly principles is by collecting data or
3. Parsimony : When facing two competing theories…
4. Testability : scientific theories should be testable (confirmable or falsifiable) using currently
available research techniques
- Operational definitions Hypothesize
Research designs and data collection techniques in psychology
Naturalistic Observation: Passive observation. Observers do not change or alter ongoing
Correlational studies tell us about relationships between variables
Why correlational studies do NOT tell us whether one variable causes change in another variable?
-Directionality problem (is variable A causing change in variable B, or is variable B causing change in
-Third-variable problem (is variable C, unknown variable in the study, causing changes in both variables
A and B?)
Therefore, we can’t make causal claim in correlational study.
-Sometimes researchers have no choice but to rely on correlational studies (e.g. when it is unethical, or
impossible to manipulate variables in an experiment)
-Independent variable: variable being manip
