he slept

Richard Atkinson & Richard Shiffrin
proposed the classic three-stage processing model of memory (sensory memory
to short-term memory to long-term memory)

Diana Baumrine

Walter Cannon & Philip Bard
Cannon-Bard theory of emotion; the idea that the body’s response and the feeling of
emotion are experienced SIMULTANEOUSLY

Dorthea Dix
an advocate of mental hospitals and humane treatment for the mentally ill

Francis Galton
in his book, English Men of Science, stated “Nature is all that a man brings with him into the world;
nurture is every influence that affects him after his birth.”

John Garcia
challenged the idea that any association can be learned equally well; did research with lab rats and
radiation…his findings violated the notion that for conditioning to occur, the US must immediately follow the CS (the rats, when given radiation hours after tasting a particular flavor, avoided that flavor in the future); also tested other senses (sight and sound) and found the rats did not develop aversions to the other senses, only taste…this contradicted the behaviorists’ idea that any perceivable stimulus could serve as a CS

Howard Gardner
argued that we don’t have an intelligence, but eight multiple intelligences

Michael Gazzaniga
had experimented on cutting the brains of cats and monkeys with no serious ill effects to the
animals; his experiments revealed the significant purpose of the corpus callosum; did the HE●ART experiment with split-brain patients

Nobel prize winners that demonstrated that the visual cortex has feature detector neurons that receive information and respond to a scene’s specific features—to particular edges, lines, angles, and movements

isolated what he felt were 10 basic emotions, most of which are present in infancy; others have argued
that there are more, but he believes those other emotions are a combination of the 10 he’s identified

a pioneer in American psychology and a prominent functionalist; encouraged explorations of down-to-
earth emotions, memories, will power, habits, and moment-to-moment streams of consciousness;

Nature side of intelligence debate; argued that intelligence is approximately 80% due to heredity; he felt that difference in mean intelligence scores for different races, nationalities, and social classes was due more to heredity than to environment

Mary Cover Jones
an associate of behaviorist John B. Watson; used an exposure therapy to rid “Peter” of his fear of
rabbits; doing the opposite of what Watson had done with Little Albert, she sought to replace his fear of rabbits with a CR that is incompatible with fear

discovered a part of the hypothalamus that provides a pleasurable reward; accidentally discovered when trying to test the reticular formations of rats by placing electrodes on this region

Allan Paivio
his dual code theory suggests that information is better remembered when it is represented in both
semantic and visual codes because this allows for storage of both the word and image

Lloyd & Margaret Peterson
studied short-term memory; tested individuals by having them remember 3-consonant
groups and prevent rehearsal by having them count backwards from 100 in groups of 3; their findings were that without active rehearsal, short term memories have a short and limited life

a reformer on the brutal treatment of mental patients; insisted madness was not a demon possession but a
sickness of the mind caused by severe stress and inhumane conditions

(generalized to depression with humans)

Sir Charles Sherrington
British physiologist that inferred there must be a brief interruption in the transmission of neural
impulses, thus discovering synapses

B.F. Skinner
known for his work with operant conditioning; developed the operant chamber, also known as the Skinner box

Charles Spearman
studied intelligence; believed that there was a general intelligence or g factor; he believed that those
who scored high in one factor of intelligence would tend to score high on other factors

partial report procedure; believed more information enters our sensory memory than what enters our
short-term memory

Roger Sperry
first to propose “split-brain” surgery to help epileptic patients… but did so on animals, not humans

two neurosurgeons; first to cut a corpus callosum of a human patient in order to reduce/eliminate epileptic seizures; the outcome… it worked!

degree); wrote an influential book called The Animal Mind; second female president of the APA

noted that regardless of their magnitude, two stimuli must differ by a constant proportion (not amount) for
their difference to be perceptible; difference threshold or Weber’s law

noticed that we unconsciously shape auditory patterns (ie. tick-tock sound of a clock)

Thomas Young & Hermann von Helmholtz
Young-Helmholtz tri-chromatic theory; they knew that any color could be created by combining the light waves of three primary colors—red, green, & blue—so they inferred that the eye must have three types of color receptors, one for each primary color of light
