This study reports for the first time a selective impairment for simple addition in patient FS.
Moreover, patient VP presented with a selective impairment for simple multiplication and …

The processing of numbers has been shown to induce shifts of spatial attention in simple
probe detection tasks, with small numbers orienting attention to the left and large numbers to …

In several recent articles we have developed a model of the cognitive number-processing
and calculation system. JID Campbell and JM Clark (see record 1988-00038-001) …

Investigations of the cognitive processes involved in adults' mental arithmetic have shown
the importance of phonological rather than visual codes in performance (eg Logie, Gilhooly …
