FUNCTIONALISM: ANTECEDENT INFLUENCES Chapter 6 Lecture Prepared by: Dr. M. Sawhney TOPICS 1. Scientist Captivated by Childlike Jenny 2. The Functionalist Protest 3. The Evolution Revolution: Charles Darwin (1809-1882) 4. Individual Differences: Francis Galton (1822-1911) 5. Animal Psychology and the Development of Functionalism 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  https://www.youtube.com/watch?v=9V2N4nQAr5I 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 http://www.biography.com/people/charles-darwin-9266433 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  https://www.youtube.com/watch?v=mcM23M -CCog 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. Archives of the History of American Psychology/University of Akron 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
