In real life, humans make decisions by taking into account multiple independent factors, such as delay and probability. Cognitive psychology suggests that cognitive control mechanisms play a key role when facing complex task conditions. However, in value-based decision-making, it still remains unclear to what extent become essential the condition is complex. this study, we investigated decision-making behaviors underlying neural using multifactor gambling where participants simultaneously considered probability delay. Decision-making behavior was modulated both The behavioral effect of stronger than delay, consistent with previous studies. Furthermore, subset conditions recruited fronto-parietal activations, reaction times were paradoxically elongated despite lower probabilistic uncertainty. Notably, time elongation did not occur tasks involving single factors. Meta-analysis brain activations suggested an interpretation paradoxical increase may be associated strategy switching. Consistent interpretation, logistic regression analysis data presence decision strategies. Taken together, found novel cause prominent cortex. propose these can interpreted recruitment system situations.
