One of the major
findings of the article was the detection of positive correlations between NC
and a broad array of characteristics. People with higher levels of NC had
higher levels of the personality trait of Openness to Experience, Emotion
Stability, Agreeableness, Conscientiousness and Extraversion. There were also
positive correlations of NC with self-reported engagement in cognitive
activities, and self ratings of memory and thinking abilities. These relations
were all constant with the notion that NC may be a broad construct that could
reflect motivation to seek out intellectual challenge and to participate in
cognitively complex activities. The study also found that the results on both
internal structure and external correlates were consistent with previous
reports. It suggests that the NC scale is unidimensional and that multidimensionality
previously found may be a consequence of wording effects. Results on external
correlates showed that higher NC are related to higher levels of cognition,
openness to experience, engagement in activities, education, emotional
stability and conscientiousness, and with lower levels of negative affect. The
research article found that the meaning of NC was similar across ages. There
was no evidence of age differences in the reliability of the scale, the
factorial structure of the scale, or the test-retest stability of NC scores.

Adults had very similar relations between NC and several other measures of
cognitive functioning, activity engagement, personality, self-related
cognition, ad negative affect regardless of age. Furthermore, the results of
the study indicate that the different age trends of cognitive abilities vs NC
cannot be explained by age differences in the meaning of NC and it explains why
there are different age trends for NC and for cognitive abilities.
