The effects of reward expectation and task-irrelevant emotional content on performance and event-related potential (ERP) recordings in a cognitive conflict control task were investigated using the face-word Stroop paradigm. A precue indicating additional monetary rewards for fast and accurate responses during the upcoming trial (incentive condition; relative to a cue indicating no additional reward, i.e., nonincentive condition) was followed by the presentation of target Chinese words (male vs. female) superimposed on background emotional faces (happy vs. fearful). The face's gender was congruent or incongruent with the target Chinese words. ERP results revealed that incentive cues elicited larger P1, P3, and CNV responses compared to nonincentive cues. There was a significant three-way interaction of reward expectation, emotional content, and congruency during the target processing stage such that emotionality and congruency interacted to affect the N170 and N2 component responses during the nonincentive condition but not during the incentive condition. These results indicate that reward-induced motivation reduces the interference effect of task-irrelevant emotional information, leading to better conflict resolution.

Impairments in reinforcement learning (RL) might underlie the tendency of individuals with elevated psychopathic traits to behave exploitatively, as they fail to learn from their mistakes. Most studies on the topic have focused on binary choices, while everyday functioning requires us to learn the value of multiple options. In this study, we evaluated the cognitive correlates of naturalistic foraging-type decision-making and their electrophysiological signatures in a community sample (n = 108) with varying degrees of psychopathic traits.

Background: Critical care medicine (CCM) faces challenges in attracting new physicians due to its demanding nature. Understanding medical students' and interns' perceptions of CCM is essential to address physician shortages and improve medical training.
Objective: To evaluate the factors influencing specialty selection and explore perceptions of final-year medical students and interns toward CCM at Jazan University.

Creative problem solving and memory are inherently intertwined: memory accesses existing knowledge while creativity enhances it. Recent studies show that insights often accompanying creative solutions enhance long-term memory. This insight memory advantage (IMA) is explained by the 'insight as prediction error (PE)' hypothesis which states that insights arise from PEs updating predictive solution models and thereby enhancing memory.

Two event-related brain potential (ERP) components, the frontocentral feedback-related negativity (FRN) and the posterior P300, are key in feedback processing. The FRN typically exhibits greater amplitude in response to negative and unexpected outcomes, whereas the P300 is generally more pronounced for positive outcomes. In an influential ERP study, Hajcak et al.

Adaptive behavior in a dynamic environmental context often requires rapid revaluation of stimuli that deviates from well-learned associations. The divergence between stable value-encoding and appropriate behavioral output remains a critical component of theories of dopamine's function in learning, motivation, and motor control. Yet, how dopamine neurons are involved in the revaluation of cues when the world changes, to alter our behavior, remains unclear.
