Also, be formal paraphasias, because feedback between phonological and lexical, reinforces any pattern that corresponds to a real word (remember that in a decaying, network, feedback has an especially strong influen, process that is more resistant to the effects of decay). One explanation that has been offered is that the formal errors themselves are chance, occurrences—that is, they are either unrelated word errors where the word just, happens to be phonologically related to the target, or they are phonological errors, where the phoneme string just happens to correspond to a real word. Also, in repetition he was poorer at abstract than concrete words, could not repeat nonsense words at all—features that are reminiscent, dysphasic case NC described earlier, and which suggest an abnormally strong, reliance on lexical/semantic information during repetition.

It is too early to distinguish among these various, nonfluent aphasic production difficulties differ markedly from those put, explain fluent aphasic difficulties, and that understanding the influence of context on, word production, in its broadest sense, will be crucial to the development of future, The discussion above has outlined some of the major ways in which cognitive, neuropsychological accounts of aphasic word production have recently evolved as a, result of theoretical and methodological advances in related fields. Laine, Tikkala & Juhola, 1998; Levelt et al., 1999; Roelofs, 2004; for a recent discussion of this issue, see Rapp & Goldrick, 2004; Roelofs, 2004). In models of language processing, and based on the secondary status of reading in language development, retrieval of word meaning from a semantic system and its integration with the context are often assumed to be common for spoken and written words (Patterson and Shewell, 1987). occur more frequently than chance in both normal speakers (Dell & Reich, 1981; Harley, 1984) and in some individuals with aphasia (Blanken, 1990, 1998; Laine &, Martin, 1996; Rapp & Goldrick, 2000). The aims of the study were to investigate the usefulness of model-based assessment1) in identifying the precise nature of the underlying mechanisms responsible for the dysgraphia; and2) in designing an efficacious treatment programme that was informed by theories of normal language processing. It aims to demonstrate how these have led to a, more dynamic view of word production that emphasises processes rather than, representations, and offers new ways of understanding the diversity of word production, describes how cognitive neuropsychological accounts of aphasic word production have, evolved as a result of cross-pollination from other fields, particularly cognitive, psychology. (1982). (2007). Rather, they offer a fundamentally different view of word production, and this has important implications for both researchers and practitioners in the field. ton, 1985; Patterson & Shewell, 1987).

Nevertheless, almost all shared, the basic idea of two major steps or stages. terminates in a selection process that ensures that one unit is the clear ‘‘winner’’. Wilshire, C. E., & McCarthy, R. A.

Further, because of the fast decay in lexical and phonological, units, repetition relies almost entirely on this activati, in fact accomplished in a similar way to picture naming. Our explanation of these results is based on the Interactive Lexical Network model of lexical access; root-based cues may be more effective because they more efficiently constrain the number of lemmas activated after a cue is provided.

Some, findings that were previously puzzling suddenly began to mak, following example. model for the recognition, comprehension and production of words and non- words (Patterson & Shewell, 1987): one may recognize a word as an entry in the “auditory input lexicon” and use this to retrieve the motor plan for speaking the interpretation. In word repetition, however, both sources may be available. For example, in naming, his errors were almost always sound-related to the target (both phonemic and, paraphasias). something to do with activating multiple words in close succession. An incorr, this stage will most commonly lead to a phonological.

Rapp, B., & Goldrick, M. (2004). Lastly, imaging studies show that inner speech is correlated with activation in various language areas. Prefix-based cueing (our alternative name for initial phoneme cueing that describes these cues in Sesotho-oriented terms) was compared to a novel technique, root-based cueing (RBC). way in which errors are monitored and corrected by the speaker prior to articulation. They suggest that, in, certain types of network models (namely parallel distributed processing or PDP type, models), there may be no need for actual lexical representations at all. In addition, specific cases have been reported who produce particular. After the model is organized, various damage to the lexical system can be simulated, resulting in dyslexic and category-specific aphasic impairments similar to those observed in human patients. Considering impairments at, this finer-grained level can highlight commonalties in the deficits affecting different, ‘‘components’’, enabling us to reject the assumption that they are always, Another change that came about with spreading activation, of computer simulation studies. However, in a more continuous model, this increased competition, may prevent the target from becoming suffic, to fully gain control of the phonological retrieval process. In the model, activation was permitted to flow, not only downwards, from semantic to lexical then to phonological, but also backwards, from phonological to lexical, then to semantic uni, Martin and colleagues maintained that many of the features of NC’s performance, were exactly what would be expected if activation in the lexical and phonological, For example, his nonsense word repetition, is extremely poor because, in order to repeat nonsense words, the, activation needs to be maintained in the phonological units long enough for it to be, accurately reproduced. the strongest predictor of his errors was not word frequency, but rather word length. Our results suggest that not all verb deficits derive from the subcategorisation or thematic role complexity of verbs. This may result in, fragmented, simplified, and/or agrammatic speech. In G.

The left side of the model describes the processing associated with heard and spoken speech and the right, the processing associated with reading and writing. You can write a book review and share your experiences. Forster & Chambers, 1973; Patterson & Mor-ton, 1985; Patterson & Shewell, 1987). Models of errors of omission in aphasic. Replicating therapy for, Caplan, D., Vanier, M., & Baker, C. (1986). During auditory, comprehension, the pattern of activation initiated in the phonological units may, become partially degraded even before it can be successfully transmitted to lexica, units, so the target stimulus may be easily confused with other, phonol, related words. This idea is, illustrated in panel (c) of Figure 4. 1. For example, some such individuals perform much more poorly in, picture-naming tasks when two pictures must be named together in a single utterance, 2004; Schwartz & Hodgson, 2002). PDF. This is quite different from the non-interactive view, which generally, postulates two independent networks of lexical and phonological representations for, production and comprehension, with overlap occurring only, The potential for bidirectional flow in interactive theories provides, explanation for certain types of aphasic disorders where there are qualitatively. Another issue concerns whether activation flows, semantic to lexical then to phonologically units—or whether it can, from phonological to lexical units, and from lexical to semantic units.
