N400 to lexical ambiguity and semantic incongruity in schizophrenia

N400 to lexical ambiguity and semantic incongruity in schizophrenia.

Our previous work showed a semantic bias in interpreting ambiguous words in schizophrenia, with disproportionate misinterpretation of subordinate meanings (toast at a wedding). We proposed pre-selection in schizophrenia of dominant-meaning networks at points of lexical ambiguity, thereby misleading thought. This selection bias may be due to semantic memory hyper-priming causing strong associate...

N400 and automatic semantic processing abnormalities in patients with schizophrenia.

BACKGROUND One factor hypothesized to underlie thinking disturbance in patients with schizophrenia is abnormal or disinhibited automatic spreading activation of semantic networks, which can be assessed using the N400 event-related potential. N400 is a negative-going component elicited at about 400 milliseconds following semantic stimuli that are not primed by the preceding context. Semantic pri...

Quantifying Humorous Lexical Incongruity

Heuristics for Recovery from Residual Ambiguity and Incongruity in the Semantic Interpretations of Texts

In this paper we present the heuristic algorithms at the core of a text meaning analyzer based on the ontological-semantic approach (e.g., Nirenburg and Raskin 2004). The full analyzer takes as input natural language texts and through many levels of analysis produces text meaning representations (TMRs) formulated in a specially developed ontology-based metalanguage that covers semantic as well ...

a frame semantic approach to the study of translating cultural scripts in salingers franny and zooey

the frame semantic theory is a nascent approach in the area of translation studies which goes beyond the linguistic barriers and helps us to incorporate cognitive and cultural factors to the study of translation. based on rojos analytical model (2002b), which centered in the frames or knowledge structures activated in the text, the present research explores the various translation problems that...
