INTELLIGENCE
I. INTELLIGENCE INTRO
1. No clear definition of intelligence
a. We no longer think of intelligence as one thing but that there may be
kinds of intelligences that people possess to different degrees
2. Jensen’s Controversy
a. Racial differences in IQ
3. Mismeasure of Man by Stephan Jay Gould
a. In studies lots of scientific bias because of bad research methodology
b. One of first attempts to rank intelligence of the world was by looking at
the size of the brain (skull size)
II. IMPORTANT MILESTONES
A. Sir Francis Galton
1. First important modern figure to consider regarding the study of
intelligence
2. Father of Eugenics
3. Several Important contributions
a) Observed psychological traits within a population of
individuals tend to fall along the bell-shaped curve
b) First to use correlation method to study how 2 traits vary
with each other
c) Helped give us logic of twin/adoption studies to see
contributions of nature vs nurture
d) Used anthropometric measurement to study intelligence
(1) Gave people sensory discrimination tasks to
measure perceptual abilities- functions of the brain not
simply structural aspects of the brain
(2) Was looking for difference in way that peoples
brain performed
BUT his measurement did not work SO shifted the debate
from brain anatomy to functions of the brain
B. Alfred Binet

Document Summary
In studies lots of scientific bias because of bad research methodology: one of first attempts to rank intelligence of the world was by looking at the size of the brain (skull size) First important modern figure to consider regarding the study of intelligence. Observed psychological traits within a population of individuals tend to fall along the bell-shaped curve. First to use correlation method to study how 2 traits vary with each other. Helped give us logic of twin/adoption studies to see contributions of nature vs nurture. Gave people sensory discrimination tasks to (1) measure perceptual abilities- functions of the brain not simply structural aspects of the brain (2) was looking for difference in way that peoples brain performed. But his measurement did not work so shifted the debate from brain anatomy to functions of the brain. Chronological age refers to age at which child reasons.
