  ABSTRACT: How constituent concepts of a compound concept are put together for meaning construction is an important question in cognition. Using English noun-noun compounds with a modifier+noun structure, researchers have observed relation priming between compounds that share the same relation (snowball vs. snowman) compared with those that do not (snowball vs. snowshovel), suggesting explicit use of relation information during comprehension of compound expressions. The present study examined the temporal characteristics of relation priming with event-related potentials. Participants were presented with lists of two-character noun+noun Chinese compound words and judged whether each was semantically meaningful or not. About 260ms following word presentation, the semantic N400 response was significantly reduced if a word was preceded by a prime with the same first character, indicating semantic processing of constituent morphemes. However, N400 was not modulated by manipulation of relation priming until around 340ms. Results confirm the use of relation information in semantic composition, but more critically provide the first piece of evidence that compound word comprehension involves serial processing where constituent morphemes are activated in stage one and bound by their relation in stage two.

  Article: The role of the left prefrontal cortex in sentence-level semantic integration.

  ABSTRACT: Whether left inferior frontal gyrus (LIFG) activation during sentence comprehension reflects semantic integration or domain-general cognitive control remains unclear. To address this issue, 26 participants were presented with sentences word by word during fMRI scanning and were asked to perform two semantic tasks, one explicit (semantic congruency judgment) and one implicit (font size judgment). In the two language tasks, semantic integration load was parametrically manipulated with high cloze, low cloze and semantically violated sentences. Participants also performed a classical Stroop task during scanning. Conjunction analysis of the explicit and implicit tasks revealed two regions in left inferior frontal gyrus associated with semantic integration load: one anterior region (aIFG) and one posterior region (pIFG). However, only the pIFG region was also activated during the Stroop task. These results indicate that different regions in the LIFG play different roles in semantic integration, with aIFG more important for domain-specific processing and pIFG more important for domain-general cognitive control.

• Article: Perceptual conflict-induced late positive complex in a modified Stroop task.

  ABSTRACT: To investigate the functional significance of the late positive complex (LPC) in the Stroop task, the present study recruited 22 participants and had them report the color of words in the classical Stroop task and the rotation state of words in a Rotation judgment task. Color words whose ink color was either congruent (CON) or incongruent (INCON) with the word's meaning were presented in both tasks. Consistent with previous studies, the N450 and LPC were observed in the Stroop task, accompanied by slowed reaction time (RT) in the INCON condition compared with the CON condition. Notably, a larger LPC was observed in the INCON condition than in the CON condition in the Rotation task, while RT and accuracy were comparable between the two conditions. Because the incongruence between ink color and word meaning was independent from the response, and neither influenced accuracy nor RT in the Rotation task, the results suggested that the LPC may have resulted from the perceptual conflict between ink color and word meaning.

  Article: Feedback-related negativity encodes outcome uncertainty in the gain domain but not in the loss domain.

  [show abstract] [hide abstract]
  ABSTRACT: Outcome uncertainty plays an important role in decision making. The present study used event-related potentials (ERP) combined with a simple gambling task to investigate the time course of outcome uncertainty processing in the gain and the loss domains. Behaviorally, participants showed a preference for the uncertain option in the gain domain, whereas they showed no such preference in the loss domain. In ERP analyses, the feedback-related negativity (FRN) amplitudes mirrored the behavioral results: for gains, cue-elicited FRN amplitudes were more negative for uncertain than for certain cues, whereas for losses, cue-elicited FRN amplitudes for certain cues and uncertain cues were not different. In contrast, the P300 amplitude was sensitive to the valence of cues (gains or losses) but not to the uncertainty of the outcome. These results suggest that the outcome uncertainty is rapidly and differentially processed in the gain and loss domains.

• Article: Plausibility effects when reading one- and two-character words in Chinese: Evidence from eye movements.

  ABSTRACT: Eye movements of Chinese readers were monitored as they read sentences containing a critical character that was either a 1-character word or the initial character of a 2-character word. Due to manipulation of the verb prior to the target word, the 1-character target word (or the first character of the 2-character target word) was either plausible or implausible, as an independent word, at the point at which it appeared, whereas the 2-character word was always plausible. The eye movement data showed that the plausibility manipulation did not exert an influence on the reading of the 2-character word or its component characters. However, plausibility significantly influenced reading of the 1-character target word. These results suggest that processes of semantic integration in reading Chinese are performed at a word level, instead of a character level, and that word segmentation must take place very early in the course of processing.
