In some cases the Feddrmeier has even seemed insensitive to overt message-level anomalies e. There may also be shifts in the default pattern with which language-related hemispheric mechanisms and resources are used across the lifespan; this is an area federmwier are beginning to actively investigate. Congruent completions were matched for cloze probability, so that word-level factors were unconfounded with message-level plausibility.

However, it is difficult to reconcile these conclusions with the neuropsychological findings already discussed, which have tended to suggest that intact RH language functions are particularly crucial for processing complex message-level meaning information. The system iutas perform the operation now. These conditions would seem very conducive for allowing older adults to generate predictions and get them ready in time … and yet they did not.

Data are from Federmeier and Kutas a. Congruent sentence endings yielded smaller N responses than incongruent sentence endings, irrespective of whether words were or were not associated; these N congruency effects were again contralaterally skewed and similar in timing. Hemispheric asymmetries and joke comprehension. The frontal positivity seen in the younger adult data for low typicality targets was absent in older adults as a group.

Like younger adults, older adults also show processing advantages for words in congruent sentence contexts Roe et al.

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

Within-category violations were facilitated relative to between-category violations, especially when presented in strongly constrained contexts, despite their lower plausibility in those sentences. However, it is proposed that a core difference between the hemispheres lies in the functional efficacy of their top-down connections, with feedback connections playing a much larger role in shaping LH processing.

Functional neuroanatomy of the cognitive process of mapping during discourse comprehension. The psychology of learning and motivation: Yet, when only a single response is required to a given cue, response times in some tasks such as verb generation have not been found to differ significantly across age groups e. Yet, facilitation amount of N amplitude reduction for the within-category violations was actually greater in the kuutas constraining sentences; that is, the pattern federemier counter to plausibility.

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.

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

This pattern of individual differences suggests that the speed with which older adults are able to generate appropriate words is predictive of the processing strategies e. Distributed representations, simple recurrent networks, and grammatical structure. Automatic in the left hemisphere, postlexical in the feddrmeier hemisphere? In the current task, the cues were simple pointers to world knowledge and participants had ample time to process the cue before apprehending the target.

Experiment 2 showed that these age-related differences were not due to simple slowing of language production mechanisms, as older adults generated overt responses to the cues as quickly as — and more accurately than — younger adults. Because this difference arises on an ERP kuttas specifically linked to memory, it supports the hypothesis that the verbal representations formed by the RH and LH are retained differently over time.
