Thinking ahead: The role and roots of prediction in language comprehension
Florida; A green vegetable: Spencer WD, Raz N. If age-related changes in predictive processing during sentence processing are secondary to difficulty in developing a message-level interpretation, then older adults may show predictive processing effects in this much simpler task, which loads less heavily on working memory and more heavily on world knowledge.
However, a number of language functions stand out for their relative resistance to age-related decline e. As large a subset as possible of the older adults from Experiment 1 were brought back so that language production measures could be directly correlated with ERP responses. Wechsler Adult Intelligence Scale — Revised manual. Thus, for example, processing a sentence may lead to the activation of semantic, lexical, or even perceptual features of items that are likely to appear; the ease of processing a word, even prior to lexical activation or word selection, will then be influenced by the extent to which its properties have been preactivated by the available context information.
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. Like younger adults, older adults showed significant N congruency effects for both category based relations and antonym based relations, and, as in younger adults, the antonym congruency effect peaked earlier in older adults there was also a tendency for this effect to be larger than the category effect, although that difference did not reach statistical significance.
Electrophysiological investigations of picture processing in the two cerebral hemispheres. Individual differences in working memory and reading. These behavioral data thus support the hypothesis that there may be a relative RH advantage for maintaining some aspects of verbal information across longer lags.
Hemispheric asymmetries in activation and integration of categorical information. An event-related brain potential study of semantic integration, gender expectancy, and gender agreement in Spanish sentence reading. Eye movements reveal the on-line computation of lexical probabilities during reading. Memory for previously relevant information.
Thus, we expect young participants to elicit frontal positivity to the low typicality targets as compared with both the high typicality targets and the incongruent ones as, in sentence processing work, anomalous endings have not been associated with frontal positivity: Hemisphericity and top-down processing of language.
By tracking language comprehension through the use of real-time, direct brain measures such as event-related potentials, we are thus beginning to build a picture of when, where, and how the brain comes to build meaning from words. Data are from Federmeier and Kutas a. Please note that during the production process errors may be discovered which could affect the content, and all legal disclaimers that apply to the journal pertain.
Instead, this outcome would suggest that older adults are less likely to recruit relatively intact language production mechanisms during comprehension — or that the recruitment of these processes is less efficacious.

The complete cue phrase was presented in the center of the screen for ms, followed by a variable inter-stimulus interval ISI; a variable interval was used to temporally jitter anticipatory ERP responses of between and ms. 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 impact of semantic memory organization and sentence context information on spoken language processing by younger and older adults: Correspondingly, norming data showed that both violation types were rated as less expected and less plausible in the strongly than in the weakly constraining contexts.
Another finding that emerged in this study was a repetition effect on the P2, with larger responses to new than to old test words. At the same time, however, there are also age-related changes in the availability and quality of that context information. N4 to spoken sentences in young and older subjects.
In addition, category cues e. Surprise but not coherence: Thus, a full understanding of the cognitive and neural bases of normal comprehension will require elucidation of both the individual and the interactive contributions of mechanisms distributed across the two cerebral hemispheres.
Age-related and individual differences in the use of prediction during language comprehension
Follow-up comparisons were then done within each group separately. Studies of a split-brain patient. Semantic integration in reading: Responses to the strongly constrained endings, however, were larger and, thus, less facilitated for older adults, and N effects of constraint response differences between words in weakly and strongly constrained sentences were delayed by more than ms. Older adults also elicited a left lateralized positivity to incongruent targets, especially in the antonym condition.
Incremental interpretation at verbs: If so, the subset of older adults who did show predictive processing patterns may be those who are able to overtly produce responses in time.
