| summary | Cohen and Dehaene (1995) examined number processing in two alexic patiends, G.O.D and S.M.A.
Both patients presented a subtle number naming deficit in which their ability to name a pair of single digits was largely intact in the context of making a quantity comparison (choose the larger) but severely impaired in the context of simple addition (stating their sum).
Cohen and Dehaene suggested that naming of Arabic digits can utilize semantic or asemantic pathways but that number-fact retrieval (2+3=?)
can inhibit the semantic route for digit naming. This leads to predictions about effects of number processing context on speed to name numbers.
A series of experiments with neurologically intact participants provides support for the hypothesis that number processing context does reconfigure the cognitive architecture for naming numbers. |
