Abstract The integration of multisensory objects containing semantic information involves processing of both low-level co-stimulation and high-order semantic integration. To investigate audiovisual semantic integration, we utilized bimodal stimuli (AV, simultaneous presentation of an auditory sound and a visual picture; An, simultaneous presentation of an auditory sound and a visual noise; Vn, simultaneous presentation of a visual picture and an auditory noise; Fn, simultaneous presentation of a...
Abstract In this study, we investigated the effect of environmental sounds on ERPs during an auditory task, by having participants perform the same dual task in two different outdoor environments. Participants performed an auditory oddball task while cycling outside both in a quiet park and near a noisy roadway. While biking near the roadway, an increased N1 amplitude was observed when evoked by both standard and target tones. This may be due to attentional processes of enhancing sound processin...
Abstract Rinsing the mouth with a carbohydrate solution has been suggested as a means to enhance aspects of both physical and cognitive performance. However, evidence in support of these assertions is relatively weak. The purpose of this study was to investigate the effects of a carbohydrate mouth rinse solution on motor speed, inhibition, and sustained attention as indexed by both behavioral and neuroelectric measures. Using a double-blind, placebo-controlled, within-subjects crossover design, ...

Abstract Performance-monitoring event-related brain potentials (ERPs), such as the error-related negativity (ERN) and reward positivity (RewP), are advocated as biomarkers of depression symptoms and risk. However, a recent meta-analysis indicated effect size heterogeneity in the ERN and RewP literatures. Hence, advocating these ERPs as biomarkers of depression might be premature or possibly misguided due to the selective reporting of significant analyses on the part of researchers (e.g., p-hacki...

Abstract This study aimed at examining how social distance modulates costly prosocial behaviors in the gain (i.e., helping another win a good outcome) and loss contexts (i.e., helping another avoid a bad outcome). To this end, participants were instructed to choose between two lotteries – One of the two lotteries was costly to their payment and always better than the other, which would result in the other person having a greater chance of ending up with more money – to give another person (a fri...

Abstract Individual differences in reward responsiveness can be reliably measured at the neurophysiological level using the reward positivity (RewP) event-related potential (ERP). Alterations in reward responsiveness impact physical and psychological health. In particular, prior research indicates that a reduced RewP prospectively predicts depressive symptoms. However, it remains unclear whether RewP can be modified through intervention or prevention. The present study examined the effects of a ...

Abstract Nogo- N2 and P3 are the two major components in the neural time course of response inhibition (RI) and are both related, albeit differently, to dopamine (DA). However, contradictory results from previous studies imply that there may be an interaction effect between DA and task difficulty on the neural time course of RI. To investigate this, we assessed the correlation between spontaneous eye blink rate (EBR) and N2/P3 elicited by the Go/Nogo tasks across various task difficulties, manip...

Abstract Introduction Recent evidence suggests that biomechanical parameters of the brain, such as Brain Tissue Pulsatility (BTP), could be involved in emotional reactivity. However, no study has investigated the impact of an emotional task on BTP. We used the ultrasound method of Tissue Pulsatility Imaging (TPI) to assess changes in BTP to exciting and relaxing classical music, in a musical perception task, as a validated paradigm to assess emotional reactivity. Methods 25 healthy volunteers we...

Abstract Exposure to stress has a variety of consequences on human behavior and cognition. Although widely investigated, the impact of stress on working memory remains inhomogeneous. Individual differences in neuroendocrine responsiveness, for example, cortisol responses, may be factors that explain previous inconsistent results. This study assessed the role of cortisol responsiveness in the effects of psychosocial stress on working memory. To examine working memory processes, we analyzed both b...
Abstract The error-related negativity (ERN) is one of the most researched event-related potentials in the study of cognitive control, and it is thought to capture preconscious error-monitoring. ERN amplitude is known to be modulated by trait and state differences in affect, yet most ERN studies use ‘cold’ cognitive tasks that do not directly target affective processes involved in cognitive control. For example, speeded response-time tasks that elicit the ERN typically use neutral stimuli (e.g., ...
