Abstract
The current study presents the test-retest reliability data for the ECO (Examen Cognitif par Ordinateur) computerised cognitive battery developed by Ritchie et al. (1993). Repeat testings were conducted using a sample of 36 healthy elderly with normal cognitive functioning. Sixteen of the battery's 23 subtests yielded significant correlation coefficients ranging from .42 to .90 (Pearson's r). A mild practice effect was detected with two of the seven memory tests and two of the seven visuospatial tests (p <.05). Comments about the sources of measurement error and recommendations for further test development are made.
