SCIENTIST CAPTIVATED BY CHILDLIKE
JENNY
Jenny, 2 year-old orangutan displayed at the London
Zoo (1838)
Wore a girl’s dress
Sat at a table
Used a spoon to eat from a plate
Drank from a cup
Understood her keeper’s directions
Recognized what she wasn’t allowed to do

THE FUNCTIONALIST PROTEST
Charles Darwin changes psychology:
No longer concerned with the structure of consciousness but its
function
Functionalism: concerned with how the mind functions and how it is
used by organisms to adapt to the environment
Focus on practical, real-world consequences
Protest against Wundt and Titchener’s systems
Asks: What does the mind do? How does it do it?
THE EVOLUTION REVOLUTION:
CHARLES DARWIN (1809-1882)
Evolution: suggestion that living things change
with time
Idea does not begin with Darwin:
Erasmus Darwin: wrote that all warm-blooded
animals evolved from a single living filament
Jean-Baptiste Lamarck: theory of evolution that
emphasized modifications to bodily form in
order to adapt
Theory of inheritance of acquired characteristic
Charles Lyell: suggests earth had passed
through various stages of development
Jean-Baptiste Lamarck
THE EVOLUTION REVOLUTION (CONT’D.)
Zeitgeist of the time:
Scientists learning more about the species that inhabit earth (biology)
Centuries of accepting biblical explanations leaves questions: How
could Noah fit so many species into the arc?
Examples like Jenny show that animals can be similar to human beings
Discovery of fossils that didn’t match living species
DARWIN’S LIFE
Grandfathers were two of the most famous men in England
Did poorly in school
Interest in natural history
Was a naturalist on the HMS Beagle
1831-1836
Explored South America and Tahiti
Gather data on animal and plant life
Darwin began to formulate his theory of evolution
Charles Darwin (1809-1882)
THE JOURNEY OF THE BEAGLE

DARWIN’S LIFE (CONT’D.)
Three years later: developed neurotic
symptoms: trembling, depression, vomiting, etc.
Worry caused by fear of his theory being
condemned
Works on his book for 22 years before presenting
it to the public
Motivated by another theorist (Wallace) on the
verge of a similar idea
WHY DARWIN PUBLISHED HIS THEORY
June 1858, received a letter from Alfred Russel
Wallace
Wallace wrote a theory of evolution similar to
Darwin
Asked questions, “Why do some die and some live?”
This was addressed at the Linnaean Society
In 1859, Darwin published “Origin of Species”
Immediately sold out
ON THE ORIGIN OF SPECIES BY MEANS OF
NATURAL SELECTION
Fundamental points
Natural selection of traits best suited for the
environment
Survival of the fittest: elimination of those
not fit for the environment
Variation is a law of heredity
The finches’ beaks: evolution at work
In just one generation, whether conditions
cause changes in beak size
Evidence that evolution can be rapid

DARWIN’S INFLUENCE ON PSYCHOLOGY
The Expression of Emotions in Man and Animals,
Darwin’s most directly related work to
psychology.
Focus on animal psychology
Emphasis on the functions rather than the
structure of consciousness
Acceptance of methodology and data from
many fields
Focus on the description and measurement of
individual differences
INDIVIDUAL DIFFERENCES: FRANCIS GALTON
(1822-1911)
Worked on mental inheritance and individual
differences in human capacities
Similar research by Juan Huarte (1530-1592)
Book entitled: The Examination of Talented
Individuals
Example of the influence of Zeitgeist
GALTON’S LIFE
Born in 1822
Estimated IQ of 200
Began medical training at age 16
After the death of his father, he pursued his own interests
Darwin’s Cousin
Became interested in studying the inheritance of
human abilities and individual differences.
Many interesting achievements
Invented the weather map
Was the first to suggest using fingerprints for
identification.
STATISTICAL METHODS
Galton was impressed with Quetelet’s “average
man”.
Developed his own statistical methods in order
to quantify and analyze data
Applied the normal curve to mental
characteristics
Proposed that the mean and standard deviation
were the most useful for describing data
Used correlation as a tool and graphed the
correlation coefficient
The correlation coefficient is denoted as : r
MENTAL INHERITANCE
Looks at examples of genius in history
Shows that genius is inherited and a specific form of
genius
Proposes eugenics to foster the improvement of
inherited qualities in humans
Proposed the development of intelligence tests
Financial incentives for those who score high
MENTAL TESTS
Galton assumed intelligence can be measured with
sensory capacity
Established the Anthropometric Laboratory, 1884.
Mental tests: tests of motor skill and sensory
capacities (unlike intelligence tests)
Invented instruments to measure motor capacity
Collected data from more than 9,000 people
Each person took a total of 17 tests
A century later this data was analyzed and found to
have high test retest correlation
Galton established his Anthropometric
Laboratory to collect data on human
psychometric capacities.

INDIVIDUAL DIFFERENCES:
FRANCIS GALTON (1822-1911) (CONT’D.)
Galton’s work in other areas:
The association of ideas: Galton researched the
diversity of associations and the reaction time
Created a list of 75 words
After one week, measured reaction time for word
associations
40 percent associations come from childhood
Developed the word association test
Mental imagery: Galton used survey methods to
determine that mental imagery also fits a normal
curve
Arithmetic by smell and other topics: Galton’s
attempt to count by odors instead of numbers
ANIMAL PSYCHOLOGY AND THE
DEVELOPMENT OF FUNCTIONALISM
Darwin’s theory of evolution leads to a focus on animal psychology
Idea that no sharp distinction exists between humans and animals
Increased interest in how animals function
May reveal knowledge of how humans function
GEORGE JOHN ROMANES (1848-1894)
Wrote the first book on comparative psychology: Animal Intelligence
Developed the “mental ladder” on which he ordered animals in terms of mental
functioning
Method of anecdotal observations, termed introspection through analogy
C. Lloyd Morgan (1852-1936)
Recognized the weaknesses in anecdotal and introspection-by-analogy methods
Law of parsimony: the notion that animal behavior must not be attributed to a higher
mental process when it can be explained in terms of a lower mental process
Believed animal behavior should not be overestimated to higher mental processes
