sciences

The Origins of Psychology
1500 and 1600s

not the center of the universe, the sun was.
Galileo Galilei- used a telescope to confirm the
predictions of Copernicus
Descartes- proposed a link between the body
and mind

Marmaduke Sampson
Studied “why crime occurs”
Believed behavior was the result of the shape of the head
Phrenology- the practice of examining bumps on a person’s skull to determine that person’s intellect and character traits
Inspired scientists to consider the brain instead of the heart as responsible for human behavior

Wilhelm Wundt’s
Structuralism
identified structures of the mind
introspection
systematic, detailed self-reports

Williams James’
Functionalism
identified the functions and purposes
of the mind
stream of consciousness
human interactions with outside world
why is human thought adaptive?

Inheritable Traits
Sir Francis Galton
Wanted to understand how heredity influences a
person’s abilities, character, and behavior.
His study focused on genius being a hereditary
trait
Did not consider that distinguished families
may also have exceptional environments and
socioeconomic advantages

Inheritable Traits
Scientists recognized flaws in Galton’s
research
They came up with the theory that “a
person’s heredity and environment interact
to influence intelligence”

Gestalt Psychology
German Psychologists
Max Wertheimer
Wolfgang Kohler
Kurt Koffka
