about those data.

empirical research.

• Values: are personal statements
o “Abortion should not be permitted in this country,”
o “I will go to heaven when I die”
o “It is important to study psychology”
• Facts: are objective statements determined to be accurate though empirical study, such as

Challenges of studying psychology
1. people vary and respond different in different situations
2. almost all behaviour is multiply determined (processed by many factors).
a. These multiple causes are not independent of one another
b. They are associated such that when one cause is present, other causes tend to be present as
well.
3. Human behaviour is caused by factors that are outside our conscious awareness.
a. Making it impossible for us, as individuals, to really understand them
i. Genetically
ii. Family history
iii. Almost impossible to know cause and of concern
Section 2: the evolution of psychology: history, approaches, and questions
Structuralism

experience.
o Goal was to create a periodic table of the elements of sensations
§ Big map on what’s going on in the brain
o Structuralists used the method of introspection
§ Asking research participants to describe exactly what they experience as they work on
mental tasks) to attempt to create a map of the elements of consciousness
Functionalist
• Influenced by Charles Darwin theory of natural selection.
o Must have adapted to serve a particular function in human experience
