How the body and brain create emotions, memories, and sensory experiences.
Sample Issues
• How do evolution and heredity influence
behavior?
• How are messages transmitted within the body
& brain?
• How is blood chemistry linked with moods and
motives?
• What emotional and mental traits are we born
with?
• To what degree are mental disorders
determined by
heredity?
Francis Galton
The collection of data for his first important book, Hereditary
Genius, marks the beginning of his psychological work. The thesis of the book is that "genius" or "talent" is
genetically rather than
environmentally determined (Forrest, 1995).
Biological Perspective
Pierre Paul Broca
Gustav Theodor Fechner
Fechner’s greatest achievement
was in his study of
exact relationships in psychology and aesthetics.
He formulated Fechner's law,
which says that, within limits, the intensity of a sensation increases as the logarithm of the stimulus.
William James
Mind Body Duality
Studied intelligence and the role of the frontal lobes of the brain. He espoused the theory of cortical specialization for both senses and motor operations and challenged the idea of localization in the brain. He studied memory and learning by looking at the affects of brain damage in lab animals. Lashley brought
to light the controversy between
localization and those proposing
holistic brain function.
