Abstract:
29 Parkinsonians and 29 controls matched for age and schooling were tested for memory by means of a free recall test (serial position curve) and two spans (verbal and non-verbal). The free recall test yields three measures: primacy (item 1); secondary memory (items 2-7) and recency (items 8-12). The Parkinsonians displayed a selective deficit of primacy, which is taken to be evidence of defective functioning of the Central Executive in the Working Memory model.
