This document provides an introduction to physiological psychology. It defines physiological psychology as the branch of biological psychology that deals with the workings of the mind and body and how the brain relates to behavior. It explains that physiological psychology studies how bodily functions are directly linked to the brain and how small changes in the brain can affect behavior. The document then discusses some important figures in the history of the field, including Hippocrates' idea that emotions originate in the brain, Galen's theories about brain functions and personalities, Descartes' view of the body as a machine responding to stimuli, and Muller's ideas about nerve fibers relaying messages between the brain and body.

1. INTRODUCTION TO
PHYSIOLOGICAL
PSYCHOLOGY

2. WHAT IT IS?
• Physiology
– from the Greek word “Physis” meaning nature

5. WHY IS IT IMPORTANT IN
PSYCHOLOGY?
• Psychology studies the behavior of an individual.
• The behavior of an individual is govern by the changes in the
body.
• The changes in the body is profoundly affected by the main
provider of information throughout the body which is the brain.
• The subject is important to be able to understand how small
changes in the brain relates to the differences in the actions of
an individual more precisely in the person’s behavior.

6. HOW DID IT BEGUN?
• Hippocrates (400-370 B.C.)
- Ancient Greek physician who is also highly regarded as the
father of medicine.

journey to say that thoughts and emotions are generally done in
the brain.

7. • Aristotle (384 – 322 B.C.)
- Father of proto-psychology.

everything is constructed by it; the essential entity
of life.

8. • Galen (A.D. 130-200)
- Was well known for his contribution to the study of
anatomy but also made a theory about personalities.
- He disagreed & believed that brain to be a separate
construct from the hearts as nature place it.
- He understood the workings of the mind into fluids that
define a person’s personality.

9. • Rene Descartes (17th century)
- Known as the father of Modern Philosophy.
- He constructed the idea that the human body is like a
mechanical object, that the environment is the stimuli that
dictates actions.
- He conceptualized that human beings require an outside
stimuli that exhibit actions (reflex).
HOW DID IT BEGUN?

10. • Johannes Muller(19th century)
- German physiologist and comparative anatomist, one of
the great natural philosophers of the 19th century.
- Constructed the idea that there are nerve fibers that relay
messages to the parts of the body specifically the organs.
- His idea lay view the idea of the doctrinal of specific
nerve energies which relay the format of the electrical relay
of information from the brain to the different parts of the
body.
