| B.F. Skinner
B. F. Skinner was born March 20, 1904
He died August 18, 1990
Early Years:
B.F. Skinner
described his Pennsylvania childhood as "warm and stable." As a boy,
he enjoyed building and inventing things; a skill he would later use in his own
psychological experiments. He received a B.A. in English literature in 1926
from Hamilton College, and spent some time as a struggling writer before
discovering the writings of Watson and Pavlov. Inspired by these works, Skinner
decided to abandon his career as a novelist and entered the psychology graduate
program at Harvard University.
Skinner married
Yvonne Blue in 1936, and the couple went on to have two daughters, Julie and
Deborah.
Career:
In 1945, Skinner moved to Bloomington, Indiana and became Psychology
Department Chair and the University of Indiana. In 1948, he joined the
psychology department at Harvard University where he remained for the rest of
his life. He became one of the leaders ofbehaviorism and his work contributed
immensely to experimental psychology. He also invented the 'Skinner box,' in
which a rat learns to obtain food by pressing a lever.
Awards:
1966 Edward Lee Thorndike Award, American Psychological Association
1968 - National Medal of Science from President Lyndon B. Johnson
1971 - Gold Medal of the American Psychological Foundation
1972 - Human of the Year Award
1990 - Citation for Outstanding Lifetime Contribution to Psychology
Research:
Operant Conditioning
B.F. Skinner is famous for his research on operant conditioning and negative reinforcement. He developed a device called the "cumulative recorder," which showed rates of responding as a sloped line. Using this device, he found that behavior did not depend on the preceding stimulus as Watson and Pavlov maintained. Instead, Skinner found that behaviors were dependent upon what happens afterthe response. Skinner called this operant behavior.
Schedules of Reinforcement
In his research on operant conditioning, Skinner also discovered and described schedules of reinforcement:
The Baby Tender
B.F. Skinner also invented the "baby tender." It is important to note that the baby tender is not the same as the "Skinner box," which was used in Skinner's experimental research. He created the enclosed heated crib with a plexiglass window in response to his wife's request for a safer alternative to traditional cribs. Ladies Home Journal printed an article on the crib with the title "Baby in a Box," contributing in part to the misunderstanding of the crib's intended use.

Contributions of
Psychology
Skinner was a
prolific author, publishing nearly 200 articles and more than 20 books. In a
2002 survey of psychologists, he was identified as the most influential
20th-century psychologist. While behaviorism is no longer a dominant school of
thought, he work in operant conditioning remains vital today. Mental health professionals
often utilize operant techniques when working with clients, teachers frequently
use reinforcement and punishment to shape behavior in the classroom, and animal
trainers rely heavily on these techniques to train dogs and other animals.
