Research & Publications


My research mainly focuses on perception, memory, and various aspects of cognitive processing. I mostly use EEG and brain stimulation (TMS, tDCS, tACS) techniques to investigate these topics. Recently, I am also venturing into the field of social neuroscience with topics such as deception and moral reasoning.

My newest projects mostly involve the cognitive mechanisms behind successfull (or unsuccessful) lying. This field is qutie interesting and goes far beyond crime-scene investigation scenarios - because it happens all the time in our daily lives: we lie about our own feelings to be polite, or maybe to be politically correct, and sometimes we lie for unselfish reasons such as protecting others (e.g., white lies). Deception is a necessary element in social functioning, and so far a poorly understood one.

My work with Dr. Chi-Hung Juan focuses on the neural mechanisms of visual cognition. We used neuroimaging and stimulation techniques to study topics like visual awareness, visual attention, and visual memory. Specifically, I use transcranial magnetic stimulation (TMS) and transcranial direct current stimulation (tDCS) to modulate neural activities in the parietal cortex to investigate its role in visual working memory. We also combine these neuro-modulation techniques with imaging tools such as fMRI, ERP, and EEG time frequency analysis to uncover the processes behind the behavioral effects of neurostimulation. Recently, we found that anodal tDCS can artificially improve people's performance (at least temporarily) on a visual short-term memory task, but only if these people's natural performance fell below average.

My former advisor Bruce Bridgeman focused on embodied cognition, and we investigated how actions, such as pointing (finger) and grabbing (entire hand), can alter the way we perceive the visual scene by creating a stronger attentional engagement (a phenomenon originally discovered by Catherine Reed, 2006, and Richard Abrams, 2008). Intending to perform an action also works similarly (Tseng et al., 2010 Perception). Interestingly, this attentional engagement helps people encode more information from a scene, but disappears when one's hand(s) can no longer touch the display (Tseng & Bridgeman, 2011 Exp Brain Res). My good friend (and incredible colleague) Chris Davoli and I together have organized a Research Topic for this hand effect in Frontiers in Psychology, which includes 12 articles from 34 researchers who represent 23 institutions worldwide. For more information, or a free download of the e-book, please take a look at the Frontiers webpage: Taking a hands-on approach: Current perspectives on the effect of hand position on vision.
