tesi su memoria di lavoro ed autismo.

[@Seboz@]

Ciao a tutti,
sto iniziando a compilare una tesi bibliografica sulla memoria di lavoro nell' autismo, in particolare faccio riferimento al modello di baddeley e hitch e poi a quello di cornoldi e vecchi del 2003.
Se qualcuno ha del materiale e lo vuole condividere io accetto volentieri

Spatial Working Memory Deficits in Autism. By: Steele, Shelly D.; Minshew, Nancy J.; Luna, Beatriz; Sweeney, John. Journal of Autism & Developmental Disorders, Apr2007, Vol. 37 Issue 4, p605-612, 8p, 2 charts, 1 graph Abstract: Previous studies have reported working memory deficits in autism, but this finding has been inconsistent. One possibility is that deficits in this domain may be present only when working memory load exceeds some limited capacity. High-functioning individuals with autism performed the CANTAB computerized test of spatial working memory. Individuals with autism made more errors than a matched group of typically developing controls on this task, and were less likely to consistently use a specific organized search strategy to complete the task. Overall, these results demonstrate reduced spatial working memory abilities in autism, and extend previous findings by demonstrating that these deficits are significant when tasks impose heavier demands on working memory.

Discrepancy of performance among working memory-related tasks in autism spectrum disorders was caused by task characteristics, apart from working memory, which could interfere with task execution.

Psychiatry & Clinical Neurosciences, Jun2006, Vol. 60 Issue 3, p312-318, 7p, 2 charts, 1 graph, 1 bw Abstract: Working memory performance has been inconsistently reported in autism spectrum disorders (ASD). Several studies in ASD have found normal performance in digit span and poor performance in digit symbol task although these are closely related with working memory. It is assumed that poor performance in digit symbol could be explained by confirmatory behavior, which is induced due to the vague memory representation of number–symbol association. Therefore it was hypothesized that the performance of working memory task, in which vagueness did not cause confirmatory behavior, would be normal in ASD. For this purpose, the Advanced Trail Making Test (ATMT) was used. The performance of digit span, digit symbol and ATMT was compared between ASD and normal control. The digit span, digit symbol and ATMT was given to 16 ASD subjects and 28 IQ-, age- and sex-matched control subjects. The scores of these tasks were compared. A significantly lower score for ASD was found only in digit symbol compared with control subjects. There were no significant difference in digit span and working memory estimated by ATMT. Discrepancy of scores among working memory-related tasks was demonstrated in ASD. Poor digit symbol performance, normal digit span and normal working memory in ATMT implied that ASD subjects would be intact in working memory itself, and that superficial working memory dysfunction might be observed due to confirmatory behavior in digit symbol. Therefore, to evaluate working memory in ASD, tasks that could stimulate psychopathology specific to ASD should be avoided. [ABSTRACT FROM AUTHOR] DOI: 10.1111/j.1440-1819.2006.01507.x (AN 20857074)

Verbal and Spatial Working Memory in Autism.
By: Williams, Diane L.; Goldstein, Gerald; Carpenter, Patricia A.; Minshew, Nancy J.. Journal of Autism & Developmental Disorders, Dec2005, Vol. 35 Issue 6, p747-756, 10p, 5 charts Abstract: Verbal and spatial working memory were examined in high-functioning children, adolescents, and adults with autism compared to age and cognitive-matched controls. No deficit was found in verbal working memory in the individuals with autism using an N-back letter task and standardized measures. The distinction between the N-back task and others used previously to infer a working memory deficit in autism is that this task does not involve a complex cognitive demand. Deficits were found in spatial working memory. Understanding the basis for the dissociation between intact verbal working memory and impaired spatial working memory and the breakdown that occurs in verbal working memory as information processing demands are increased will likely provide valuable insights into the neural basis of autism.

Ciao Seboz.

Mandami un tuo indirizzo mail per PM e ti mando un po' di altri articoli dal '95 ad oggi sul tema (tutti in inglese, ovvio, ma credo tu non abbia grossi problemi).

La mi mandi un saluto a Fiorenza...

Buona vita
Guglielmo

Ciao..anche io sto iniziando la tesi sull'autismo.In particolare sui programmi di comunicazione TEACCH e ABA. Vorrei concentrarmi più che sui bimbi, sulle reazioni dei genitori che devono affrontare questa situazione...
Avete materiale????
Grazie mille....
