We investigated the relations of the Big Five personality factor of Intelle
ct or Openness to Experience with the crystallized and fluid aspects of mea
sured intelligence. Approximately 500 participants completed the Personalit
y Research Form (PRF) and the Multidimensional Aptitude Battery (MAB). An O
penness/Intellect scale, defined as the sum of four PRF scales known to be
markers of the Openness/ Intellect factor (Understanding, Sentience, Change
, and Autonomy), was substantially correlated with MAB subtests that assess
crystallized knowledge (the Verbal Scale subtests except Arithmetic), but
only weakly correlated with MAB subtests that assess fluid ability (the Per
formance Scale subtests and Arithmetic). Among the fluid ability subtests,
those containing pictures or meaningful visual stimuli were somewhat correl
ated with Openness/Intellect, whereas those containing numbers or abstract
shapes were virtually uncorrelated with Openness/Intellect. (C) 2000 Academ
