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. 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.

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

How young and old adults listen to and remember speech in noise. However, Experiment 2 revealed no evidence that older adults are actually adn than young adults at producing category exemplars or antonyms on demand.

Journal of Comparative Neurology. Differences across tasks, individuals, and groups that seem problematic and difficult to explain if one seeks a single mechanism for all language phenomena may be more readily accounted for by adopting a more multifaceted view.

This pattern makes sense given that increasing the constraint of a context provides kutzs scaffolding for semantic analysis and integration and also renders words more predictable.

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

However, various sources of evidence suggest that callosal transfer is incomplete and results in a loss of information fidelity.


Both younger and older adults responded more quickly to the federneier cues, for which correct responses were more highly associated with the cue and more lexically constrained. Although older adults as a group did not elicit the frontal positivity, analyses of individual differences revealed that a subset of older adults did show the young-like pattern associated with predictive processing, with enhanced frontal positivity selective for the low typicality targets.

To test this prediction, ERPs were recorded from young adults as they read centrally presented category cues e. 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 khtas comes to build meaning from words.

Open in a separate window. In some cases the RH has even seemed insensitive to overt message-level anomalies e.

The result, then, is that language comprehension comes to be more dominated by feedforward mechanisms. First, N responses in both VFs were affected by congruency difference between expected items and between-category violationsand there was no difference in the size or timing of this effect. Another finding that emerged in this study was a repetition effect on the P2, with snd responses to new than to old test words.

Table 2 shows accuracy data for antonym and category cues for younger and older adults.
