What the Nose Knows: Olfaction and Cognitive Abilities.
Peer reviewed Peer reviewed
Danthiir, Vanessa; Roberts, Richard D.; Pallier, Gerry; Stankov, Lazar – Intelligence, 2001
Studied the role of olfactory processes within the theory of fluid and crystallized intelligence by testing 107 Australian college students with a battery of psychometric and olfactory tests. Results indicate the likely existence of an olfactory memory ability that is structurally independent of established higher-order abilities and not related…

Performance on a Coincidence Timing Task Correlates with Intelligence.
Peer reviewed Peer reviewed
Smith, Glen A.; McPhee, K. A. – Intelligence, 1987
Timed performance measures from a coincidence timing task taking about 10 minutes are shown to have significant correlations with psychometric general intelligence in a group of 56 children. The mean absolute error across three conditions correlated -.294 with Raven's Standard Progressive Matrices scores but was sex-biased, with girls being less…

Complexity as a Reflection of the Dimensionality of a Task.
Peer reviewed Peer reviewed
Spilsbury, Georgina – Intelligence, 1992
The hypothesis that a task that increases in complexity (increasing its correlation with a central measure of intelligence) does so by increasing its dimensionality by tapping individual differences or another variable was supported by findings from 46 adults aged 20-70 years performing a mental counting task.
