It may be suggested that tests of intelligence may not be able to truly reflect levels of fluid intelligence.
22.
Stress during early childhood may also affect the child's development and have negative consequences on neural systems underlying fluid intelligence.
23.
Working memory capacity is closely related to fluid intelligence, and has been proposed to account for individual differences in Gf.
24.
Fluid intelligence involves both the dorsolateral prefrontal cortex, the anterior cingulate cortex, and other systems related to attention and short-term memory.
25.
Vocabulary performance ( considered as crystallized intelligence ) has smaller cohort effects than reasoning performance ( considered as fluid intelligence ).
26.
Research has suggested that cognitive flexibility is related to other cognitive abilities, such as fluid intelligence, reading fluency, and reading comprehension.
27.
Fluid intelligence ( Gf ) is in several ways more fundamental and is particularly evident in tests requiring responses to novel situations.
28.
Recent research has explored the idea that training on working memory tasks can transfer to improvements in fluid intelligence ( Jaeggi, 2015 ).
29.
Research on the effectiveness of interventions, and the degree to which fluid intelligence can be increased, especially after age 16, is somewhat controversial.
30.
For example, the Wechsler Adult Intelligence Scale ( WAIS ) measures fluid intelligence on the performance scale and crystallized intelligence on the verbal scale.
