Aging in context: age-related changes in context use during language comprehension.

Projecting sound onto meaning. Expanding upon this, I have developed a theoretical framework that ties together the patterns of asymmetry documented across tasks and language levels. Electrophysiology reveals semantic memory use in language comprehension.

A second hypothesis is that age-related slowing in the mechanisms needed to generate language information on demand may result in predictions not becoming available in time to impact comprehension. Fededmeier hemispheric mechanisms in the retrieval of ambiguous word meanings. Supportive contextual information seems to be able to mitigate the age-related N delays in the andd modality e. Consistent with the pattern observed in the present study, this positivity has been associated with processing wnd when predictions are disconfirmed.

It is possible that such information be-comes more important for memory judgments at long lags, when explicit memory signals are weaker.

Age-related and individual differences in the use of prediction during language comprehension

Stimuli were divided into lists such that an individual subject would see each antonym or category cue only once. The representation of the ipsilateral visual field in human cerebral cortex. Teasing these factors apart is difficult in sentence processing tasks, since the availability of an integrated message-level representation is critical for context-based prediction. Age differences in fluid and crystallized intelligence. However, such a system tends to lose stimulus-specific information, as context and expectations shape and override input features.

An event-related brain potential study of semantic integration, gender expectancy, and gender agreement in Spanish sentence reading. During sentence comprehension, older adults are less likely than younger adults to predict features of likely upcoming words.

Aging in context: age-related changes in context use during language comprehension.

Human brain potentials to frdermeier expectation and agreement in Spanish spoken sentences. Houghton Mifflin Company; The brain is an amazing pattern recognition device, and this is perhaps nowhere more apparent than in the domain of language comprehension. The appearance of the positivity in this design, and its pattern across conditions, extends our understanding in two ways.

A priori arguments against prediction in language comprehension e.

How and why do the two cerebral hemispheres interact? 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 15 trials. Although work has shown age-preservation in the ability to generate knowledge-based information such as category exemplars in off-line tasks see review in Light,much less is known about how older adults respond to these cues under time pressure.

The behavioral results confirm this, as accuracy was near ceiling for both groups, with younger adults averaging Right words and left words: This “Cited by” count includes citations to the following articles in Scholar.

More generally, independent of any particular framework, these kind of data emphasize the importance of examining cerebral asymmetries and considering the possibility of multiple mechanisms when trying to understand the nature, timecourse, and neural bases of language processes.

With RVF presentation, P2 amplitudes were larger for expected than for unexpected endings, suggesting that LH sentence processing provides top-down information that allows enhanced visual feature extraction from expected targets.

2005 adults showed N facilitation aand the presence of lexically associated words in the sentence contexts that was similar to that measured for younger adults. Such asymmetries may arise, in turn, because language comprehension mechanisms are integrated with language production mechanisms only in the left hemisphere the PARLO framework.

Thinking ahead: The role and roots of prediction in language comprehension

The simultaneous use of constraints from multiple levels will tend to strengthen and speed selection e. Electroencephalography and Clinical Neurophysiology. N mean amplitudes were then assessed in a kufas window centered on the effect peak for each group i. 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.

Automatic in the left hemisphere, postlexical in the right hemisphere?
