This study was aimed at investigating the basic mechanisms of the normal repetition priming evoked by text re-reading procedures in Alzheimer's disease (AD) patients (Monti, Gabrieli, Wilson, & Reminger, 1994; Monti et al., 1997). For this purpose, we contrasted the reading facilitation elicited by previous reading or listening to a text in a sample of AD patients and a group of age-matched normal controls. Consistent with previous evidence in normal undergraduates (Levy & Kirsner, 1989), previous listening to a text decreased the successive reading time of the same text (cross-modality priming). However, the reading facilitation elicited by previous reading of the same text (within-modality priming) was significantly larger than the facilitation evoked by previous listening. Compared to normal controls, AD patients showed intact cross-modality and within-modality priming. These data are discussed in the light of alternative hypotheses regarding the basic mechanisms of impaired and spared repetition priming in degenerative demented patients.

Abstract
This study was aimed at investigating the basic mechanisms of the normal repetition priming evoked by text re-reading procedures in Alzheimer's disease (AD) patients (Monti, Gabrieli, Wilson, & Reminger, 1994; Monti et al., 1997). For this purpose, we contrasted the reading facilitation elicited by previous reading or listening to a text in a sample of AD patients and a group of age-matched normal controls. Consistent with previous evidence in normal undergraduates (Levy & Kirsner, 1989), previous listening to a text decreased the successive reading time of the same text (cross-modality priming). However, the reading facilitation elicited by previous reading of the same text (within-modality priming) was significantly larger than the facilitation evoked by previous listening. Compared to normal controls, AD patients showed intact cross-modality and within-modality priming. These data are discussed in the light of alternative hypotheses regarding the basic mechanisms of impaired and spared repetition priming in degenerative demented patients.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
