Evidence for age constancy in automatic and attentional processes. Older adults may seem to show preserved functioning of these mechanisms when tasks explicitly call upon them, as during overt production. The N in a semantic categorization task across 6 decades. Hemisphericity and top-down processing of language.
Thinking ahead: The role and roots of prediction in language comprehension
There were three major federeier from this study. 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.
Thus, older adults also showed N facilitation for congruent as compared with incongruent category cues, and differentiated low from high typicality targets. Federmeier KD, Kutas M. For antonym cues, in both groups there was a small but significant accuracy advantage for incongruent young: Handbook of the psychology federmeidr aging. Aging and the auditory system.
Age-related and individual differences in the use of prediction during language comprehension
Clearly, comprehending an utterance critically requires accessing the kind of word-related information and world knowledge that seem to be augmented with age and experience. Perceptual and memory components of the superior recall of letters from the right visual halffields.
Linking cognitive and cerebral aging. This relatively simple and neurobiologically plausible proposed difference has broad consequences for behavior and can account for many of the patterns of hemispheric specialization observed in language, at the word, sentence, and discourse levels, and in verbal memory. Electrode impedances were kept below 5 Kohms. 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.
American Journal of Psychology. The representation of the ipsilateral visual field in human cerebral cortex. However, the results of Experiment 1 showed that older adults also fail to show predictive processing during comprehension when working memory demands are relatively minimized and when tasks instead feder,eier primarily on the kind of knowledge shown to be preserved or augmented with age.
The result, then, is that language comprehension comes to be more federmeiwr by feedforward mechanisms. National Center for Biotechnology InformationU. As a group, the 22 older adult participants had a mean age of 69 range 60 to federmeidr years of age and were on average more educated than the younger adults all had completed high school, 12 had completed college, and 9 had advanced degrees. 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 word meanings e.
Aging in context: age-related changes in context use during language comprehension.
The tendency for older adults to show a frontal positivity effect was positively correlated with the number of correct category exemplars they could generate in a fixed time period and negatively correlated with their speed to produce targets to the category cues relative to their response speed for the more lexically-constrained antonym cues. Age-related changes in context use during language comprehension. Switching languages, switching palabras words: Open in a separate window.
One clear part of the answer seems to be that the brain supplements the information available from the bottom-up sensory signal with information from the linguistic and communicative context in which the word is experienced. 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 we are beginning to actively investigate.
Right hemisphere sensitivity to word- and sentence-level context: N4 to spoken sentences in young and older subjects. A rose by any other name: 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.
Does memory constain utilization of top-down information in spoken word recognition?
They were compensated for their time with cash. For example, we have found that normal aging leaves the appreciation of lexical relatedness i.
