Perceived control plays a crucial role in risk-taking behavior, but its neural effect on reward dynamics in risky and ambiguous decision making remains unclear. Here, we addressed this issue by measuring participants' (N = 40) EEG activity while they were performing a wheel-of-fortune task. Participants either made choices themselves (a high control condition) or followed the computer's choice (a low control condition) under risky or ambiguous decision contexts. Behavioral and rating data showed a stronger control effect in the risky compared to the ambiguous decision context. In parallel, we found an effect of perceived control on choice evaluation (indexed by the cue-P3) in the risky but not ambiguous context. However, the control effect was more pronounced during feedback anticipation (indexed by the stimulus-preceding negativity) and outcome appraisal (indexed by delta oscillation) in the ambiguous context compared to the risky context. Together, our findings suggest that experiencing control alters reward dynamics in uncertain decision making, with dissociable effects between risk and ambiguity.

Aims: The purpose of this study was to assess the association between mindfulness and depressive symptoms experienced by people diagnosed with schizophrenia, controlling for the impact of their demographics and their perceived public stigma against mental illness.

Background: Tuberculosis (TB) is a global health problem, including in Indonesia, with East Lombok as a high prevalence region. Although control programmes have been implemented, TB cases remain high. Patient behaviours that are less supportive of treatment, such as non-compliance and social stigma, pose a challenge to TB control efforts in this area.

Previous studies have suggested that systemic viral infections may increase risks of dementia. Whether this holds true for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus infections is unknown. Determining this is important for anticipating the potential future incidence of dementia.
