10. Important People in the

Aristotle (384 –322 BC) – He made assumptions
out of observation regarding human behavior. He
believed that all beings, humans included, have
souls, which animate them. Humans, however,
compared to other animal, have rational souls.
Thus, humans are not only, physical, but also
rational. He also theorized about learning,
memory, motivation, emotion, perception and
personality.

11. Important People in the
Dev’t. of Psychology
Rene Descartes
(1596 – 1650) - supported the
view that humans enter the
world with an inborn store of
knowledge. He argued that
some ideas (such as God, the
self, perfection and infinity) are
innate. He is also notable for
his conception of the body as
a machine that can be studied.

12. Important People in the
Dev’t. of Psychology
John Locke
(1632–1704) - Believed
that at birth the human
mind is a “tabula rasa”
or a blank slate, on
which experience
“writes” knowledge.

13. Important People in the
Dev’t. of Psychology
Charles Darwin
(1809 – 1882) - He is the
author of the Law of
Natural Selection or
Theory of Evolution;
inspired the Psychological
school of thought,

Wilhelm Wundt – Considered as the “Father of
Modern Psychology.” He established the first
experimental laboratory for the study of Psychology,
in Leipzig, Germany, 1879. He created a machine
that measured the time lag between people’s
hearing a ball hit the platform and their pressing a

“atoms of the mind” – the fastest and simplest
mental processes.

primitive biological instincts. It
considered all humans
