Abstract Stress has been defined in many ways and is typically induced as a response to a threat to homeostasis. Stress affects decision-making, and the effects of stress on subcomponents of decision-making can be indirectly measured through EEG. The purpose of this study was to investigate the effects of acute stress on the neural correlates of decision-making. We hypothesized that acute stress would decrease the reward and attentional sensitivity, seen through reduced P300 and reward positivity component activity. The results were that the mean percent change from baseline for heart rate was higher for the stress condition during the TSST. The stress group also had decreased positive affect scores and increased negative affect scores for the STAI questionnaire and decreased positive affect scores for the PANAS questionnaire. Additionally, while not significant, there was a trend towards reduced P300 component activity in the stress condition, potentially indicative of reduced attentional sensitivity. Further research is needed to explore the implications for reward sensitivity, utilizing multiple tasks, and including cortisol measurement. Stress is common to everyday life and has been implicated chronically in numerous health conditions. Understanding how stress affects executive function, particularly decision-making, is therefore crucial in both the short- and long-term.             Keywords: stress; decision-making; ERPs; P300 component; reward positivity component               *This research was supported by a Jamie Cassels Undergraduate Research Award, University of Victoria.

The Impact

ABSTRACTStress and blunted reward processing are risk factors for mood disorders, including Major Depressive Disorder (MDD). The experience of acute stress reduces fMRI correlates of reward-related neural activity; however, few studies have examined how acute stress impacts measures of reward derived from event-related potentials (ERPs). The current study examined the impact of an acute stressor on the Reward Positivity (RewP), an ERP that indexes reward sensitivity, in twenty-seven college students. Participants completed a monetary reward task while they placed their left hand in cold water set at 13 degrees Celsius (i.e., acute stress condition) and again while their hand was placed in room temperature water (i.e., control condition). These conditions were separated by one week and performed in a counter-balanced order across participants. The results revealed that the RewP amplitude was blunted in the acute stress condition compared to the control condition. Moreover, there was a trend toward this effect interacting with self-reported depressive symptoms: the RewP was only reduced among individuals who reported low depressive symptoms. The current study suggests that an acute stressor reduces the RewP, and that this effect might be moderated by current depressive symptoms. Future studies might examine the temporal association between reward processing and stress —and how they interact to predict depressive symptoms.

The influence of acute severe stress or extreme emotion based on a Network-Oriented modeling methodology has been addressed here. Adaptive temporal causal network model is an approach to address the phenomena with complexity which cannot be or hard to be explained in a real-world experiment. In the first phase, the suppression of the existing network connections as a consequence of the acute stress modeled and in the second phase relaxing the suppression by giving some time and starting a new learning of the decision making in accordance to presence of stress starts again.

Neural Correlate Of Consciousness

This essay critically examines the extent to which binocular rivalry can provide important clues about the neural correlates of conscious visual perception. Our ideas are presented within the framework of four questions about the use of rivalry for this purpose: (i) what constitutes an adequate comparison condition for gauging rivalry's impact on awareness, (ii) how can one distinguish abolished awareness from inattention, (iii) when one obtains unequivocal evidence for a causal link between a fluctuating measure of neural activity and fluctuating perceptual states during rivalry, will it generalize to other stimulus conditions and perceptual phenomena and (iv) does such evidence necessarily indicate that this neural activity constitutes a neural correlate of consciousness? While arriving at sceptical answers to these four questions, the essay nonetheless offers some ideas about how a more nuanced utilization of binocular rivalry may still provide fundamental insights about neural dynamics, and glimpses of at least some of the ingredients comprising neural correlates of consciousness, including those involved in perceptual decision-making.

Neutral Affect

We conduct a random-assignment experiment to investigate whether positive affect impacts time preference, where time preference denotes a preference for present over future utility. Our result indicates that, compared to neutral affect, mild positive affect significantly reduces time preference over money. This result is robust to various specification checks, and alternative interpretations of the result are considered. Our result has implications for the effect of happiness on time preference and the role of emotions in economic decision making, in general. Finally, we reconfirm the ubiquity of time preference and start to explore its determinants. (DJEL D12, D83, I31)
