Theoretical perspectives that help researchers decide what questions to ask & sets of tools with which to answer the questions
Ideas that have been passed down & modified throughout history

8. What is psychology? The science of behavior and mental processes Also…
Explanation

Scientific investigation
What is psychology?

9. The Goal of Psychology
Psychologists engage in the study of psychology in order to understand, explain and predict and control behavior.
Psychologists use evidence and create theories to explain these things.

10. Psychology’s Early Roots
We have ALWAYS been concerned with who we are and why we do things, but only in the last 100 years has psychology become a science.
Certain people took a role in the formation of psychology as a science
Socrates
Plato
Aristotle

11. Plato and Socrates (427-347 B.C.)
Socrates & Plato Believed we are born with complete knowledge within our soul.
Knowledge continues when the body dies
Learning – a process of inner reflection to discover the knowledge within us.
Mind and body are different

12. Aristotle Aristole – (384-322 B.C.) Student of Plato
Knowledge acquired through experience, not automatically in-born.
Argued that careful observation, not just logic alone, was essential to explain things in the world.

13. Philosophical Developments
Rene Descartes ( )
Dualism: human body contains 2 distinct entities:
Material body
Mind/soul
What separates man from animals is thought (which requires having a soul)
Soul and mind are used interchangeably, here.
Religion = strong hold on academics at this time
Soul & physical body communicate with each other via threadlike stuctures

14. Problems with Descartes
How can a non-material entity (soul/mind) have a material effect on the body?
How can the body follow natural laws, yet be moved by a mind that does not?
Precludes a scientific investigation of the mind.

15. Hobbes: Materialism
Basic axiom: everything (behavior, thought, etc.) can be understood in terms of the body’s physical processes, especially the brain.
Sort of the anti-Descartes
Paved the way for empiricism
Founder of materialism
Not the type of materialism that we think of today.
Empiricism- the idea that knowledge comes from sensory experiences
Materialism – everything that happens is as a result of interactions with matter

16. Francis Bacon ( )
Proposed that knowledge can only be drawn from our experience and that observations must be used.
Early advocate for empiricism (knowledge comes from what we experience)

17. John Locke ( )
Proposed the idea that humans are born totally blank of knowledge.
He coined the term “tabula rasa” (blank slate) to describe his point.
