ABSTRACT In a study of lexical ambiguity processing, responses to homographs were examined in a word association task. The context of repeated exposures of a homograph was manipulated by requiring a response to a word related to a meaning of the homograph on the trial prior to homograph presentation. A change of that relationship reduced the effectiveness of the contextual item as a prime on the second occurrence of the homograph. In response to a third unprimed occurrence of the homograph, associations were consistent with a conclusion that when semantic contexts are opposed, a "primacy effect" is obtained. The overall effects in the studies reported are seen as consistent with the theoretical view of Simpson and Kang (1994) that processing and responding to one meaning of a homograph result in the inhibition of alternative meanings. A mechanism to account for that inhibition is proposed.

    ABSTRACT: This study investigated noun-verb retrieval patterns of 30 adults with chronic undifferentiated schizophrenia and 67 typical adults, to determine if schizophrenia affected nouns (associated with temporal lobe function) differently from verbs (associated with frontal lobe function). Stimuli were homophonic homographic homonyms, balanced according to frequency of occurrence, where N>V, N<V, or N approximately V. Systematicity effects, in which systematic noun and verb meanings are transparently related (e.g., "drain"), and unsystematic noun and verb meanings appear to be unrelated (e.g., "seal"), were also examined. Adults with schizophrenia overselected nouns, in both phrase and sentence tasks. Typical participants strongly preferred verbs in the phrase task, but nouns in the sentence task. Frequency of occurrence yielded statistically significant effects in control, but not in experimental groups. Effects of systematicity were statistically significant in some, but not all tasks and conditions. Age of typical participants was not significant. Learning outcomes: Readers will be introduced to (a) evidence of noun-verb organization in the brain; (b) evidence of ambiguous noun-verb preference to differentiate the language of schizophrenia from the language of typical adults; and (c) evidence of ambiguous noun-verb preference to differentiate the language of schizophrenia from fluent aphasia.

    ABSTRACT: Despite previous findings, Klin, Ralano, and Weingartner (2007) found transfer benefits across unrelated passages. After processing an ambiguous phrase in Story A that was biased toward its sarcastic meaning, readers were more likely to interpret the identical phrase in Story B as sarcastic, even though it contained no disambiguating information. In the present experiments, we found both repetition effects (a benefit for the lexical items) and meaning selection effects (a benefit for the selected meaning of the phrase) with short delays between Stories A and B; with longer delays, only repetition effects were found. Whereas decreasing the elaboration of the phrase eliminated both effects, moving the disambiguating context from before to after the phrase eliminated meaning selection effects only. We conclude that meaning selection effects, which are based on conceptual overlap, are more sensitive to context changes and less robust than repetition effects, which are based on both perceptual and conceptual overlap.
