Relatively little is known about the neural bases of the Big Five personality trait Openness/Intellect. This trait is composed of 2 related but separable aspects, Openness to Experience and Intellect. On the basis of previous behavioral research (C.

To investigate the potential role of working memory (WM) processes, we assessed delay discounting, intelligence (g), WM (span tasks, 3-back task), and WM-related neural activity (using functional magnetic resonance imaging) in 103 healthy adults. Delay discounting was negatively correlated with g and WM.

- - The study explored how different types of intelligence (fluid and crystallized) are linked to various brain regions, using brain scans of 225 young adults to analyze these connections.
- - It found that crystallized intelligence is more connected to brain structure (like cortical thickness), while fluid intelligence is more tied to brain function (like blood flow during reasoning tasks).
- - The researchers created a model that accurately predicted IQ based on brain data, showing that intelligence is influenced by multiple brain areas with different roles, supporting theories of distributed brain function.
When assessed with performance measures, Emotional Intelligence (EI) correlates positively with the quality of social relationships. However, the bases of such correlations are not understood in terms of cognitive and neural information processing mechanisms. We investigated whether a performance measure of EI is related to reasoning about social situations (specifically social exchange reasoning) using versions of the Wason Card Selection Task.

Activation elicited by an analogical reasoning task that required both complex working memory and integration of abstractly similar relations was compared to activation elicited by a non-analogical task that required complex working memory in the absence of abstract relational integration. A left-sided region of the frontal pole of the brain (BA 9/10) was selectively active for the abstract relational integration component of analogical reasoning.
