Jinxiao is a graduate student in the Psychology Department. His research interest generally lies in how the "emotion system" and the "cognition system" interplay with each other. Specifically, he is interested in how cognitive control can modulate emotion processes as well as how emotion can affect cognitive processes. He is also interested in how the emotion-cognition interaction relates to psychological health. He uses neuroimaging, physiological, eye-tracking, and behavioral methods to investigate these research questions. In his recent work, he studies how sleep influences emotion regulation and other emotional processes. He is a big fan of interdisciplinary research (psychological, biochemical, and computational) and open science practice.
Sleep Deprivation Undermines the Link Between Identity and Intergroup Bias.
This research seeks to bridge two findings - on the one hand, top-down controlled processes inhibit display of intergroup bias; on the other one hand, sleep deprivation impairs cognitive control processes. Connecting these two proven statements, begs the question: would sleep deprivation also influence intergroup bias? This intriguing link has hardly been explored in extant literature. To fill this gap, we theorize through the lens of social identity. Previous research has shown that individuals who share a common identity with an outgroup are more motivated to inhibit biases toward the outgroup than do their counterparts who do not endorse such common identity. We predicted that this motivated inhibition would be compromised by sleep deprivation. Across two studies, as predicted, we found that only when an individual has adequate sleep did common ingroup identity attenuate the display of intergroup bias, whereas individuals with short habitual sleep (Study 1) or after one-night sleep deprivation (Study 2) displayed equally high levels of intergroup bias regardless of their high or low levels of common ingroup identity. In the global context of incessant intergroup bias and diminishing sleep time, our findings offer new insights for understanding and handling intergroup bias.

Using emotion regulation strategies after sleep deprivation: ERP and behavioral findings.
Cognitive, affective & behavioral neuroscience
Sleep deprivation is suggested to impact emotion regulation, but few studies have directly examined it. This study investigated the influence of sleep deprivation on three commonly used emotion regulation strategies (distraction, reappraisal, suppression) in Gross's (1998) process model of emotion regulation. Young healthy adults were randomly assigned to a sleep deprivation group (SD; n = 26, 13 males, age = 20.0 ± 1.7) or a sleep control group (SC; n = 25, 13 males, age = 20.2 ± 1.7). Following 24-h sleep deprivation or normal nighttime sleep, participants completed an emotion regulation task, in which they naturally viewed or applied a given emotion regulation strategy towards negative pictures, with electroencephalographic (EEG) recordings. A reduction in the centroparietal late positive potential (LPP) amplitudes towards negative pictures from the naturally viewing condition to a regulated condition was calculated as an index of regulatory effects. Comparisons between the two groups indicated that sleep deprivation significantly impaired the regulatory effects of distraction and reappraisal on LPP amplitudes. Suppression did not reduce LPP amplitudes in either group. In addition, habitual sleep quality moderated the effect of sleep deprivation on subjective perception of emotional stimuli, such that sleep deprivation only made good sleepers perceive negative pictures as more unpleasant and more arousing, but it had no significant effect on poor sleepers' perception of negative pictures. Altogether, this study provides the first evidence that sleep deprivation may impair the effectiveness of applying adaptive emotion regulation strategies (distraction and reappraisal), creating potentially undesirable consequences to emotional well-being.
