The value associated with response alternatives has been observed to impact rapid choices while slower decisions remain relatively unbiased. Here we aim understand how the decision process is redirected towards goal-relevant evidence after initial prioritisation and propose that conflict detection cognitive control serve as underlying mechanism. We recorded electroencephalography (EEG) from participants performing a speeded binary choice task based on price of realistic food stimuli naturally also encompassed subjective preferences. Our findings indicate preferred were consistency selected faster, irrespective amount task-relevant information available in absence any motor or attentional anticipation, suggesting fast automatic integration value-based information.

Consistent our hypothesis, results show incongruent trials, where objective compete, mid-frontal theta (MFT) activity was heightened predicted accuracy, indicating monitoring conflict.

In essence, this study provides foundation for comprehending value-biases are overcame within brain, illustrating need use more ecological paradigms better multifaceted interactions characterising human behaviour real-world scenarios.

To form coherent multisensory perceptual representations, the brain must solve a causal inference problem: to decide if two sensory cues originated from same event and should be combined, or they came different events processed independently. According current models of integration, during this process, integrated (common cause) segregated (different causes) internal are entertained. In present study, we propose that process involves competition between these alternative engages mechanisms conflict processing. test hypothesis, conducted experiments, measuring reaction times (RTs) electroencephalography, using an audiovisual ventriloquist illusion paradigm with varying degrees intersensory disparities. Consistent our hypotheses, incongruent trials led slower RTs higher fronto-medial theta power, both indicative conflict. We also predicted intermediate disparities would yield power when compared congruent stimuli large disparities, owing steeper models. Although prediction was only validated in RT experiments displayed anticipated trend. conclusion, findings suggest potential involvement integration spatial information.

Sensory systems evolved to provide the organism with information about environment guide adaptive behaviour. Neuroscientists and psychologists have traditionally considered each sense independently, a legacy of Aristotle natural consequence their distinct physical anatomical bases. However, from point view organism, perception sensorimotor behaviour are fundamentally multi-modal; after all, modality provides complementary same world. Classic studies revealed much where how sensory signals combined improve performance, but these tended treat multisensory integration as static, passive, bottom-up process. It has become increasingly clear this approach falls short, ignoring interplay between action, temporal dynamics decision process many ways by which brain can exert top-down control integration. The goal issue is highlight recent advances on higher order aspects processing, together constitute mainstay our understanding complex, its neural basis.

During film viewing, humans parse sequences of individual shots into larger narrative structures, often weaving transitions at edit points an apparently seamless and continuous flow. Editing helps filmmakers manipulate visual to induce feelings fluency/disfluency, tension/relief, curiosity, expectation several emotional responses. We propose that the perceptual dynamics induced by editing can be captured a predictive processing (PP) framework. hypothesise discontinuities produce discrepancies between anticipated actual sensory input, leading prediction error. Further, we magnitude error depends on predictability each shot within flow, lay out account based conflict monitoring. test this hypothesis in two empirical studies measuring electroencephalography (EEG) during passive viewing excerpts, as well behavioural responses active detection task. report neural modulations boundaries across three levels depth, showing greater for edits spanning less predictable, deeper transitions. Overall, our contribution lays groundwork understanding from PP perspective. This article is part theme issue 'Art, aesthetics processing: theoretical perspectivess'.
