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
