To examine changes in semantic memory organization and use during aging, we recorded event‐related potentials as younger older adults listened to sentences ending with the expected word, an unexpected word from same category, or a different category. Half of contexts were highly constraining. In both groups, words elicited less negativity 300–500 ms (N400) than ones, smaller N400s when these categorically related. Whereas showed greatest N400 reduction but related high constraint contexts,...
Recent neuropsychological and imaging data have implicated different brain networks in the processing of word classes, nouns being linked primarily to posterior, visual object-processing regions verbs frontal, motor-processing areas. However, as most these studies examined words isolation, consequences such anatomically based representational differences, if any, for items sentences remains unclear. Additionally, some languages many (e.g. `drink') are class-ambiguous, i.e. they can play...
Abstract Effects of normal aging on the use sentence context information during language comprehension were examined by measuring younger and older adults' event‐related potential (ERP) responses to congruent sentence‐final words as a function contextual constraint. Half contexts strongly constraining, rendering target word very predictable, whereas other half weakly constraining. Both age groups elicited smaller N400 in than constrained contexts, but this effect was significantly later for...
Using event-related potentials (ERPs), the authors investigated influences of sentence context, semantic memory organization, and perceptual predictability on picture processing. Participants read pairs highly or weakly constraining sentences that ended with (a) expected item, (b) an unexpected item from category, (c) category. Pictures were unfamiliar in Experiment 1 but preexposed 2. ERPs to pictures reflected both contextual fit as do words same contexts (K. D. Federmeier & M. Kutas,...
Researchers using lateralized stimuli have suggested that the left hemisphere is sensitive to sentence-level context, whereas right (RH) primarily processes word-level meaning. The authors investigated this message-blind RH model by measuring associative priming with event-related brain potentials (ERPs). For word pairs in isolation, associated words elicited more positive ERPs than unassociated similar magnitudes and onset latencies both visual fields. Embedded sentences, these same showed...
Abstract Linking print with meaning tends to be divided into subprocesses, such as recognition of an input's lexical entry and subsequent access semantics. However, recent results suggest that the set semantic features activated by input is broader than implied a view wherein serially follows recognition. EEG was collected from participants who viewed items varying in number frequency both orthographic neighbors associates. Regression analysis single item ERPs replicated past findings,...
The "F" in FN400 denotes a more frontal scalp distribution relative to the morphologically similar N400 component-a distinction consistent with hypothesized distinct roles of familiarity memory versus language. However, no direct comparisons have substantiated these assumed dissimilarities. To this end, we manipulated short-term semantic priming during recognition test. Semantic effects on were indistinguishable from at same latency, and strongly modulated "FN400," despite having influence...
