In simple cases, the patterns seen for everyday, normal i.

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

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. Joel Voss Northwestern University Verified email at northwestern. In addition, federmeer analyze individual differences to examine what cognitive skills and resources are conducive to the use of predictive processing strategies during language comprehension.

Van Nostrand Reinhold; Thus the language comprehension system seems to be able to make detailed, multifaceted predictions about fairly specific aspects of upcoming words. During sentence comprehension, older adults are less likely than younger adults to predict features of likely upcoming words.

Thus, nad was no evidence for age-related decline on the speeded generation task, anx some evidence for small but reliable age-related benefits. Within-category violations were facilitated relative to between-category violations, especially when presented in strongly constrained contexts, despite their lower plausibility in those sentences.

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

Oxford University Press; 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. Stimuli consisted of the phrasal cues antonym cues and category fededmeier from Experiment 1. Standard deviations in parenthesis. Please review our privacy policy.

Open in a separate window.

The fact that it was a test of rapid, cued production that explained the pattern of effects that would be seen in a language comprehension task further supports the contention that the younglike effect pattern reflects covert generation processes in the form of predictions about features of likely upcoming words—perhaps reflecting a link between language comprehension and language production mechanisms an idea that will be explored in more detail in a subsequent section of this review.


Scope of word meaning activation during sentence processing by young and older adults. In the ERP signal, such consequences are observed in the form of a frontally-distributed positivity elicited by unexpected but plausible words when these are encountered in the face of a strong prediction for a different item e. In those cases a different exemplar of as high a rank as possible was used. As discussed, prediction would seem to afford a number of advantages for comprehension, including the potential for increased processing efficiency and reduced susceptibility to noise.

The timecourse — ms and distribution maximal over prefrontal electrode sites of this positivity are the same as that seen for plausible but unexpected words completing sentence frames. Instead, facilitation was a function of both the featural similarity between these items and the words most expected in the contexts and the strength of the prediction for those expected but not presented words.

Free associations of older adults to single words and conceptually related word triads. The cerebral hemispheres cooperate to performcomplex but not simple tasks. Primes were presented centrally and targets were lateralized to the LVF and RVF; participants named the targets after a delayed cue. 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.

New articles related to this author’s research. Results Behavior A delayed congruency judgment task was used to ensure that participants were attending to the stimuli and appreciating the relationship between the cues and targets. Critically, despite equivalent cloze probabilities, within-category violations also elicited smaller Ns than the between-category violations, in line with the prediction-based account of context effects. A growing body of data thus supports the idea that LH processing is more expectancy driven, involving the preactivation of likely upcoming items words, pictures at multiple levels, whereas RH processing seems to integrate new information in a more bottom-up fashion.

Models of visuospatial and verbal memory across the adult life span. In other cases, cooperation between multiple systems may afford processing strategies that neither individual processor is capable of supporting alone.

The top part of Figure 1 shows the pattern of results for auditory presentation; the pattern for kuats presentation was the same. University of Iowa; Peak latency of the N effect — i. Normative data for representatives of categories.


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

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 znd prediction during comprehension.

An event-related potential study of lexical relationships and prediction in context.

This pattern is reminiscent of findings in other domains suggesting that older adults may be less likely to routinely engage top-down mechanisms to, for example, promote memory for verbal material e. Methods, theory, and applications. In turn, this strong connectivity makes it more likely that bottom-up activation of that information will engage frontally-mediated top-down processing mechanisms, like those involved in prediction.

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. Four hypotheses in search of data. My profile My library Metrics Alerts. Older adults also elicited a left lateralized positivity to incongruent targets, especially in the antonym condition.

Evidence that predictive processing becomes less likely or less efficacious with kufas can also be seen in the results of an fedeermeier using the stimuli from Federmeier and Kutas b sentence pairs ending with expected exemplars, within-category violations, and between-category violationsin this case presented to younger and older adults as natural speech Federmeier et al. However, we might then expect to see individual differences, driven by verbal fluency as in Federmeier et al.

Individual differences in working memory federmeker reading. Furthermore, strikingly, even the small degree of facilitation for the within category violations is driven by responses in the low, rather than the high, constraint contexts—consistent with the rated plausibility of these items see the bottom half of Figure 2.

In the second experiment, these same word pairs were then embedded in sentence contexts, wherein the targets formed plausible and implausible completions, as in the following examples:.
