PSYA02 Lecture 10: Measuring Intelligence
− Galto’s Athropoetri Approah
o Believed ppl learn about world through their senses
▪ Ppl with superior sensory abilities would be able to learn more about it
▪ Thus argued that sesory ailities should e idiator of a perso’s
intelligence
o Created set of 17 sensory tests and began testing ppl in his anthropometric lab
o Anthropometrics: methods of measuring physical and mental variation in
humans
o One of his colleagues took test to USA ad deteried ppl’s ailities o differet
sensory tests not correlated with each other
▪ Could have good eyesight and bad hearing eg.
▪ If to easures do’t orrelate ell ith eah other, at oth idiate
same thing
▪ Also found sores o sesory tests did’t predit grades
▪ Led to aadoig of Galto’s theory
− Stanford-Binet Intelligence and Thinking Test
o Alfred Binet argued intelligence should be indicated by more complex thinking
processes: eg memory, attention
▪ View has influenced most intelligence researchers to this day
▪ Intelligence: ability to think, understand, reason and adapt to or
overcome obstacles
• From this perspective, intelligence reflects how well ppl able to
reason and solve problems
o Binet and Simon tasked with developing test for French children to identify the
mentally handicapped ones who would benefit from special education
▪ Developed first IQ test via trial and error and gave it to samples of kids
from different age groups to establish avg. score for each age
▪ Biet argued that kid’s sore easured for her etal age
• Mental Age: avg. intellectual ability score for kids of specific age
o 7 year old kid with test score same as avg for 7 year olds
means she has mental age of 7
o 7 year old with same avg scores as 10 year olds means she
has mental age of 10
o Stanford-Binet test: test intended to measure innate levels of intelligence
▪ Differed from Binet who believed his test was measure of kids current
abilities, not innate capacity
• Binet believed test scores were changeable, this test believed
they were more fixed

Document Summary
Stanford-binet intelligence and thinking test: alfred binet argued intelligence should be indicated by more complex thinking processes: eg memory, attention, view has influenced most intelligence researchers to this day. Wais: most common intelligence scale used for adults and adolescents. Included in full scale iq category bc greater working memory capacity and processing speed allows more cognitive resources to be devoted to reasoning and solving problems. Raven"s progressive matrices: intelligence test based on pictures, not words which makes in less affected by language or cultural background. Key issue with many intelligence tests like wais is that questions favor ppl from test developer culture or who primarily speak same language as he/she: puts ppl from different cultures or languages at disadvantage. Rpm test has tasks measuring extent to which test takers can see patterns in shapes and colours within a matrix and then determine which shape or color would complete the pattern.
