According to Flynn, which of the following are correct? Select all that apply.a) Using current norms‚ the average IQ for those three generations back is 70.b) Using early norms (from three prior generations)‚ the current average IQ is 130.c) Using current norms‚ an IQ of 70 is considered the cutoff for intellectual disability.d) Using current norms‚ an IQ of 130 is considered the cutoff for giftedness.e) Three generations ago‚ the majority of people were intellectually disabled.
a) b) c) d)
According to Flynn, the correct options are:
a) Using current norms, the average IQ for those three generations back is 70.
c) Using current norms, an IQ of 70 is considered the cutoff for intellectual disability.
d) Using current norms, an IQ of 130 is considered the cutoff for giftedness.
Option b is incorrect because using early norms (from three prior generations) may not accurately reflect the current average IQ.
Option e is also incorrect because it is not a generalization that can be made about an entire generation. Intellectual disability is defined by IQ scores below 70, but it does not mean that the majority of people in a generation are intellectually disabled.
