| Annotation | The performance of adults ranging in age from 20 to 86 on two tasks requiring different types of counting operations was examined. Sub-proportional age effects for incrementing speed and enumeration speed (counting 5 to 8 objects) indicate that some types of counting processes are exempt from the slowing effects of ageing. Increased age was associated with a diminished frequency and slowing of subitizing (counting 4 or more items), as well as with slowing in the speed of initiating the incrementing process, but the course of age-related slowing for these measures is described by different functions. These results indicate that cognitive slowing is not equivalent for different types of processes involved in counting and numbering judgments. |
