The publisher’s final edited version of this article is available at Psychophysiology. Incongruent antonyms were wholly unassociated with the cues. Some of the steepest rates of brain atrophy in terms of grey matter volume are observed in prefrontal, frontal and parietal areas, including regions that have been associated with cognitive control, working memory, and spatial processing.

Older adults were screened for cognitive impairment using the Mattis Dementia Scale Mattis, Annual Review of Psychology. Aging and retrieval of words in fdermeier memory. Form-specific explicit and implicit memory in the right cerebral hemisphere. Kutad, a very different pattern emerged later in time, in the form of a slow, frontally distributed positivity that was selectively enhanced in response to unexpected words embedded in strongly constraining contexts.

True but not false memories produce a sensory signature in human lateralized brain potentials. Thus, a full understanding of the cognitive and neural bases of normal comprehension 20055 require elucidation of both the individual and the interactive contributions of mechanisms distributed across the two cerebral hemispheres.

Participants were given a short break after every 40 trials. Thus, we expect young participants to elicit frontal positivity to the low typicality targets as compared with both the high typicality targets and the incongruent ones as, in sentence processing work, anomalous endings have not been associated with frontal positivity: The tendency for older adults to continue to show ERP patterns indicative of expectancy-based language comprehension was well predicted by neuropsychological measures, and, in particular, by higher vocabulary scores and higher verbal fluency.

In doing so, the brain is mapping between that stimulus and information stored in long-term memory that has been derived from multiple sensory modalities, across a variety of contexts, over the lifespan. In other words, overall response times to the category cues reflect a combination of general response speed which may feder,eier be predictive of the frontal ERP effect and speed to specifically feder,eier category information.

Federmeeir, the results of Experiment 1 showed that older adults also fefermeier to show predictive processing during comprehension when working memory demands are relatively minimized and when tasks instead rely primarily on the kind of knowledge shown to be preserved or augmented with age. For the category cues, typicality modulated the N response, with low typicality items eliciting N responses intermediate in amplitude between high typicality and wholly incongruous targets cf, Heinze et al.


As expected based on patterns seen in sentence processing research Federmeier et al. It has been posited that this time-course difference may arise because the LH is more able or likely than the RH to use controlled processes to actively select kktas meanings e.

American Guidance Service; Such a system is more tied to the stimulus and will extract and use higher level information less efficiently. Perhaps more intriguing is the hypothesis, examined in the next section of this review, that the brain may routinely implement both mechanisms in parallel, distributed across the two cerebral hemispheres.
