ABSTRACT
BACKGROUND:
Fluid intelligence (Gf) is a critical cognitive ability that is predictive of real-world outcomes, and it has been a persistent aim to characterize its neural architecture. PROCEDURE We advance our prior research by applying latent class analysis to evaluate individual differences in the neural and cognitive foundations of Gf over the course of a 16-week randomized, multi-modal intervention trial in neurologically healthy, younger adults (Nâ¯=â¯424).RESULTS:
Controlling for pre-intervention ability, three latent classes described individual performance at post-intervention and one group (nâ¯=â¯71) showed greater gains in visuospatial reasoning and high performance at post-intervention. The high performance group was predicted by larger anterior cingulate cortex, caudate and hippocampus volumes, and smaller middle frontal, insula and parahippocampal cortex volumes.CONCLUSION:
Regions that support cognitive control, working memory, and relational processes differentiated individuals who had higher Gf ability at pre-intervention and demonstrated a cumulative better response to the intervention.Palavras-chave
