Thinking ahead: The role and roots of prediction in language comprehension
Cognitive neuroscience of aging: Stimuli were divided into lists such that an individual subject would see each antonym or category cue only once. Inference deficits in right brain-damaged patients.
Although older adults as a group kutad not elicit the frontal positivity, analyses of individual differences revealed that a subset of older adults did show kkutas young-like pattern associated with predictive processing, with enhanced frontal positivity selective for the low typicality targets. Negative voltage is plotted up in this and all subsequent figures.
Group comparisons N N latency and amplitude were assessed at the 11 medial centro-posterior channels where such responses are characteristically most prominent e. Probabilistic word pre-activation during language comprehension inferred from electrical brain activity. Important for the focus of the present study is the fact that older adults as a group notably failed to elicit the frontal positivity to CAT-LO targets that was observed in the younger participants and that has been associated with processing consequences arising from the use of prediction during comprehension.
Modulation of event-related potentials by word repetition: The availability of top-down information allows the system to rapidly generalize away from the input, and the federmsier higher level activity is then fed back down, resulting in changes at lower levels that prepare the system to process likely upcoming stimuli.
Reviewed are studies using event-related potentials to examine when and how sentence context information is used during language comprehension.
Event-related brain potential measures. Lateral brain function, emotion, and conceptualization. At bottom is shown, for those older adult participants who completed both Experiments 1 and 2, a scatterplot with trendline of the relationship between, on the x-axis, normalized response time differences in the language production task of Experiment 2 average RT to produce correct responses to category cues minus average RT to produce correct responses to an antonym cues, divided by average overall correct RT and, on the y-axis, the size, in microvolts, of their frontal positivity effects from Experiment 1.
Their combined citations are counted only for the first article. This pattern makes sense given that increasing the constraint of a context provides more scaffolding for semantic analysis and integration and also renders words more predictable.
Thus, there was no evidence for age-related decline on the speeded generation task, and some evidence for small but kktas age-related benefits.
Age-related and individual differences in the use of prediction during language comprehension
Form-specific explicit and implicit memory in the right cerebral hemisphere. Some words do, some words don’t sometimes, some places.
This pattern is quite striking, given that an RVF advantage is almost always observed for verbal material. Examination of the psychometric literature.

Sentence processing strategies in healthy seniors with poor comprehension: Hemispheric asymmetries in global and local processing: An event-related brain potential study of semantic integration, gender expectancy, and gender agreement in Spanish sentence reading.
Under-recruitment and nonselective recruitment: Older adults as a group seem either less likely to engage predictive processing mechanisms during comprehension or less effective at doing so. The role of the right hemisphere in the interpretation of figurative aspects of language: These changes were correlated with measures of the availability of working memory resources in the older adults.
Anticipating words and their gender: Semantic processing in the right hemisphere may contribute to drawing inferences from discourse. Electrophysiology reveals semantic memory use in language comprehension M Kutas, KD Federmeier Trends in cognitive sciences 4 12, Indeed, aging is associated with change along many dimensions of cognitive functioning, including attention, memory, and executive control.
The impact feeermeier semantic memory organization and sentence context federmeieg on spoken language processing by younger and older kutqs Indeed, however, the RH seems to encode and retain different aspects of verbal stimuli, affording it advantages in some circumstances. Responses to antonym cues were counted as corrected if they were the expected lexical item from Experiment 1 or a reasonable synonym of it e.
The time course of automatic lexical access and aging.

Influences of context, semantic memory organization, and perceptual predictability on picture processing.
A comparison of the Battig and Montague norms with the responses of adults between the ages of 20 and Journal of memory and Language 41 4, Presentation to either VF resulted in reduced N amplitudes for high typicality compared with incongruent targets, showing that both hemispheres can assess the fit of clear category members and nonmembers.

Comprehension of pronouns in young and older adults. Age differences in recall and recognition. An additional 6 older adult participants 1 man, 5 women were recruited from the same population of San Diego community dwelling older adults.
Participants were given a short break after every 40 trials.
