those considered mentally deficient).

attributed to genetic factors.

heritable, but environment plays a crucial role in
maximizing potential.

S
alcoholic during pregnancy”

mixture of environmental factors (nurture) and genetic
factors (nature)
■ G
enes provide a range of possible outcomes (i.e.,
one’s IQ could be 40 – 160). This genetic makeup
interacts with the environment one is raised in.
● Poor-quality upbringing -> possible IQ of 40
● High-quality upbringing -> possible IQ of 160
● C
ultural Test Bias:Traditional IQ tests measure cultural
knowledge (ex. “Who wrote Huckleberry Finn?”), which may
disadvantage those from different backgrounds. Culture-fair
tests, like Raven’s Progressive Matrices, were developed to
address this.
