This study aimed to investigate the mechanisms underlying joke comprehension using event-related potentials (ERPs). Fourteen healthy college students were presented with the context of a story without its joke or nonjoke ending, and then, when the story ending was presented, they were asked to make a funny/unfunny judgment about these endings. The(More)
Event-related brain potentials (ERPs) were used to examine the electrophysiological effect of working memory (WM) load on involuntary attention caused by a task-irrelevant sound in an auditory–visual distraction paradigm. The different WM loads were manipulated by requiring subjects to remember the order of either three digits (low-load condition) or seven(More)
Event-related brain potentials (ERPs) were measured to study the electrophysiological mechanisms of subliminal priming of traumatic episodic memory. Twenty-four Chinese subjects who had experienced the great Sichuan earthquake in 2008 were classified either as normal control or as post-traumatic stress disorder (PTSD) subjects. Results showed that(More)
The effects of the modified Stroop task on ERP were investigated in 20 subjects who had experienced the Sichuan earthquake and a matched control group. ERP data showed that Incongruent stimuli elicited a more negative ERP deflection (N300-450) than did Congruent stimuli between 300 and 450 ms post-stimulus in the earthquake group but not found in the(More)
Event-related potentials (ERPs) were recorded to explore the electrophysiological correlates of self-referencial processing when subjects were asked to judge whether the stimuli (their hands) were their own or not. ERP results showed that: first, own hand elicited a greater positive component (P350-500) than did other hand in the time window of 350-500 ms,(More)
Event-related potentials (ERPs) were recorded to explore the electrophysiological correlates of reward processing in the social comparison context when subjects performed a simple number estimation task that entailed monetary rewards for correct answers. Three social comparison stimulus categories (three relative reward levels/self reward related to the(More)
Event-related potentials were recorded to explore the electrophysiological correlates of self-evaluation processing when participants performed intelligence social judgment tasks (judging who is more intelligent), containing self-judgment tasks (ST) and other judgment tasks (OT). Results showed that ST elicited a greater positivity (P2) than OT in 130-250(More)
The aim of this study was to investigate the temporal cortical activation patterns underlying different stages of humor comprehension (e.g., detection of incongruity stage, resolution of incongruity stage, and affective stage). Event-related potentials (ERPs) were measured when 16 subjects were apprehending cartoon pictures including humorous, non-humorous(More)
Event-related brain potentials (ERPs) were recorded to explore the electrophysiological correlates of breaking mental set when subjects performed the Chinese character-generation task. A new experimental paradigm (learning–testing model) was adopted in order to make subjects find a solution actively by using a fixed way (Rep: repetition) or a new method(More)
The electrophysiological correlates of successful insight and routine problem solving were studied in 12 healthy subjects using high-density event-related potentials (ERPs). Results showed that insight problems elicited a more negative ERP deflection (N300-800) than did routine problems between 300 and 800 ms, and a more negative ERP deflection (N1200-1500)(More)
