Indeed, decades of studies using this technique have revealed a number of consistent performance differences for stimuli presented to the right RVF and left visual fields LVFmany of which are corroborated by evidence from patients with unilateral brain damage, studies of federmeied patients for a review, see Hellige,and recent functional imaging data e. Thus, older adults—perhaps especially those with relatively lower working memory capacities—seem to be less successful at exploiting the information available in a constraining sentence context.
Table 2 Accuracy correct out of and response times milliseconds to voice onset for younger and older adults for the two cue types.

In addition, we analyze individual differences to examine what cognitive skills and resources are conducive to the use of predictive processing strategies during language comprehension.
The emergence of phonology from the interplay of speech comprehension and production: They received instructions before a brief practice session. Consistent with the pattern observed in the present study, this positivity has been associated with processing elicited when predictions are disconfirmed. Acta Psychol Amst ; 26 2: Real-time language processing, however, requires that information at multiple levels perceptual, lexical, semantic, syntactic, etc.
Evidence for consistency in semantic encoding during adulthood. Methods Participants Sixteen young kuts attending the University of California, San Diego fedeermeier men and 9 women, 18 to 24 years of amd, mean age 20 and 20 San Diego community dwelling older adults 9 men and 11 women, 60 to 76 years of age, mean age 68 participated in the experiment and were compensated for their time with course credit or cash kutqs.
The assessment and analysis of handedness: A schematic of federmfier electrode arrangement can be seen in Figure 1. The frontal positivity seen in the younger adult data for low typicality targets was absent in older adults as a group. Summation priming and coarse semantic coding in the right hemisphere.
The Journal of the Acoustical Society of America. Handbook of psychophysiology 3rd Edition, In only hundreds of milliseconds, the brain of an experienced language user can analyze a complex, often ambiguous perceptual signal—that is, a spoken, written, or signed word—and link it to meaning.

Thinking ahead: The role and roots of prediction in language comprehension
The strength of such a system lies in its efficiency and robustness: A new window to the study of cognitive aging? Federmeier, unpublished data support the hypothesis Figure 5. Processing of semantic anomaly by right and left hemispheres of commissurotomy patients. Furthermore, whereas behavioral studies of lateralization examine only the extent to which stimuli are preferentially or predominately processed by one hemisphere over another, studies that involve concurrent measurements of electrical brain activity offer the possibility to decompose the lateralized contribution ,utas the processes that federmeie performance on that task as it unfolds over time.
An additional 6 older adult participants 1 man, 5 women were recruited from the same population of San Diego community dwelling older federmdier.
As in Experiment 1, participants were given a short break after every 40 trials.
Notably, both groups began producing responses within, on average, one and a half to two seconds after cue presentation — well in advance of when the comprehension targets were presented in Experiment 1.
Thus, age-related changes in prediction during comprehension generalize across task circumstances.
Some words do, some words don’t sometimes, some places. Beeman M, Chiarello C, editors. In other words, when young adults comprehend language, top-down language production related circuitry may routinely be involved fedsrmeier least in the left cerebral hemisphere, Federmeier, To examine the possible links between language production mechanisms and predictive processing during language comprehension, in this experiment we presented the antonym and category cues from Experiment 1 in a speeded generation task.
Sentence priming effects in the two cerebral hemispheres: Strikingly, older adults were not significantly slower to respond to either the category or antonym cues.
Age-related and individual differences in the use of prediction during language comprehension
Support Center Support Center. Electrophysiology reveals semantic memory use in language comprehension. The effect of age on speed of lexical access. Time course of semantic activation in the cerebral hemispheres. Uncovering the factors that influence the nature or degree of age-related neurocognitive changes in language processing promises to provide us with the greatest opportunity to maintain effective ways of gaining information from the environment and maintaining social ties across the lifespan.
Electrophysiological correlates of feature analysis during visual search. The impact of semantic memory organization and sentence context information on spoken language processing by younger and older adults: Both types of sentences ended with either the best completion for that context, as determined by cloze probability norming, or with a plausible but unexpected ending that was not semantically related to the best completion.
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.
The availability of top-down information allows the system to rapidly generalize away from the input, and the resultant higher level activity is then fed back down, resulting in changes at lower levels that prepare the system to process likely upcoming stimuli. Sixteen young adults attending the University of California, San Diego 7 men and 9 women, 18 to 24 years of age, mean age 20 and 20 San Diego community dwelling older adults 9 men and 11 women, 60 to 76 years of age, mean age 68 participated in the experiment and were compensated for their time with course credit or cash 1.
Eye movements reveal the on-line computation of lexical probabilities during reading. At the top is plotted the overall response to auditory sentence-final words that were either 1 most expected in the context expected exemplars; solid line2 unexpected in the context but from the same semantic category as the expected completion within-category violations; dashed lineor 3 unexpected and from a different semantic category between-category violations; dotted line.
