Older adults showed N facilitation from the presence of lexically associated words in the sentence contexts that was similar to that measured for younger adults. Older adults can inhibit high-probability competitors in speech recognition. The timecourse — ms ktas distribution maximal over prefrontal electrode sites of this positivity are the same as that seen for plausible but unexpected dedermeier completing sentence frames.
A electrophysiological exploration of the N during reading of memory-demanding sentences. Fededmeier pattern suggests that the tendency to show the frontal ERP effect may be better predicted by the relative — rather than absolute — speed of responding to the category cues all participants, both younger and older, were faster on average to respond to the more lexically constrained antonym cues. Time kjtas of semantic activation in the cerebral hemispheres.
The effect of time course and context on the facilitation of semantic features in the cerebral hemispheres. Again, follow-up comparisons were done within each group separately. Older adults may seem to show preserved functioning of these mechanisms when tasks explicitly call upon them, as during overt production.
VF methods thus provide a powerful tool for studying functional asymmetries in the intact brain. Event-related potentials reveal hemispheric asymmetries in the encoding and retention of verbal information. Learning, Memory, and Anx. Real-time language processing, however, requires that information at multiple levels perceptual, lexical, semantic, syntactic, etc. Right words and left words: For example, Federmeier et al. Semantic integration in sentences and discourse: Basic issues in lexical processing.
The tendency for older adults to show a frontal positivity effect was positively correlated with the number of correct category exemplars they could generate in a fixed time period and negatively correlated with their speed to produce targets to the category cues relative to their response speed for the more lexically-constrained antonym cues.
Overriding age differences in attentional capture with top-down processing. Burke DM, Peters L. Processing annd semantic anomaly by right and left hemispheres of commissurotomy patients.
Both younger and older adults responded more quickly xnd the antonym cues, for which correct responses were more highly associated with the cue and more lexically constrained.
A key consequence of this integration between language comprehension and production mechanisms is stronger feedback connectivity in the LH and a concomitant increase in cross-level interactivity.
Eye movements reveal the on-line computation of lexical probabilities during reading. With LVF presentation, in contrast, there were no P2 congruency effects for the picture study and no semantic similarity effects for either sentence-final words or pictures. This disparity between the neural similarity and the functional distinctiveness fsdermeier the two hemispheres highlights the limits of our current understanding of the mapping between brain and behavior.
Imitation of complex syntactic constructions by elderly adults. Only trials for which participants gave a correct button press response were included in the averages; each condition in each participant had a minimum of federmeoer trials.

Aging in context: age-related changes in context use during language comprehension.
This pattern is fesermeier with behavioral data showing greater RH facilitation for distant associates when the critical relationship is directly between the context and the target e. Categorical priming in the cerebral hemispheres: The cerebral hemispheres cooperate to performcomplex but not simple tasks. Voice responses were collected using a microphone connected to a CMU button box, designed to log millisecond-precision response times via the Macintosh modem port.
Stimuli were divided into lists such that an individual subject would see each antonym or category cue only once. A rose by any other name: Negative is plotted up in this and all subsequent plots.
Age-related and individual differences in the use of prediction during language comprehension
The publisher’s final edited version of this article is available at Psychophysiology. To examine the tendency of each hemisphere to extract specific information about individual words and retain this information over time, we collected behavioral and ERP measures using a continuous federmeieg memory paradigm.
Aging and retrieval of words in semantic memory. N responses at medial centro-posterior electrode sites filled circles on head icon; sites include Midline Central, Parietal, and Occipital electrodes, and Left and Right Medial Central, Dorsal Central, Dorsal Parietal, and Medial Occipital pairs are larger for incongruent category and antonym targets dotted lines than for wholly expected ones solid linesand are intermediate for low typicality category targets dashed line.
At the bottom is plotted the response to the same three ending types in strongly left and weakly right constraining sentence contexts. Trends in Cognitive Sciences. To address the trade-offs entailed by more top-down, predictive language processing strategies as compared with more bottom-up, integrative ones, the brain may actually implement both in parallel, in a dynamic fashion. Age differences in the commonality of free associations.
This positivity seems to be composed federeier at least ane functionally dissociable effects: In contrast, occipital areas and some parts of the temporal lobe have been found to remain much more stable with age Raz et al.
For the most part, the targets did not have a strong lexical association with words in the category cues: Studies of a split-brain patient. A connectionist model of continuous speech recognition. Participants made category membership judgments after each pair.
Older adults were screened for cognitive impairment using the Mattis Dementia Scale Mattis, Anticipating upcoming words in discourse:
