NeuroImage: Counterintuitive decision-making behavior in complex value decisions is associated with fronto-parietal executive control function

In real life, humans make decisions by considering multiple independent factors such as latency and probability
.

Cognitive psychology believes that cognitive control mechanisms play a key role in the face of such complex task conditions

Published in the journal NeuroImage, KojiJimura et al.
used a multifactor gambling task in which participants considered both probability and delay to study decision-making behavior and underlying neural mechanisms
.

In complex conditions, the research team studied decision-making behavior and neural activity in complex conditions
.

To separate the effects of simple and complex task conditions, they devised a gambling task with probabilistic uncertainty and delayed outcomes, and controlled for probabilistic uncertainty or delayed control tasks on outcomes (D-task, P-task )

conditions are matched so that the effects of multiple factors can be isolated and presented simultaneously
.

During the task, functional magnetic resonance imaging (fMRI) was used to record brain activity to investigate the cognitive processes specifically used in multifactorial decision-making

Furthermore, in a group of conditions that recruited fronto-parietal activation, reaction times were paradoxically prolonged despite lower probabilistic uncertainty
.

Notably, this reaction time prolongation did not occur in control tasks involving a single factor

Reaction times were paradoxically prolonged in a group of conditions that recruited fronto-parietal activation, despite lower probability uncertainty , the reaction time is paradoxically extended

A meta-analysis of brain activity suggests an explanation that paradoxical increases in reaction time may be related to strategy switching
.

Consistent with this interpretation, logistic regression analysis of behavioral data suggests the existence of multiple decision-making strategies

The paradoxical increase in reaction time may be related to strategy switching .

Taken together, this study found that a novel and complex value-based decision-making task elicits significant activation in the fronto-parietal cortex
.
Furthermore, the study suggests that these activations are related to the recruitment of cognitive control systems in complex situations
