Abstract: Over a century of research on between-person differences has resulted in the consensus
that human cognitive abilities are hierarchically organized, with a general factor, termed
general intelligence or ''g,'' uppermost. Surprisingly, it is unknown whether this body of
evidence is informative about how cognition isstructured within individuals. Using data
from 101 young adults performing nine cognitive tasks on 100 occasions distributed
oversix months, we find that thestructures of individuals' cognitive abilities vary among
each other, and deviate greatly from the modal between-person structure. Working
memory contributes the largestshare of common variance to both between- and withinperson structures, but the g factor is much less prominent within than between persons.
We conclude that between-person structures of cognitive abilities cannot serve as a
surrogate for within-person structures. To reveal the development and organization of
human intelligence, individuals need to be studied over time.
