Introduction: The Memonum test is a computerized test based on the Wechsler test for retention of direct digits. The present study evaluated the infl uence of different intervals of digits presentation and attention interference on the mnemonic performance derived from the Memonum test, in a university population. Method: Twenty-eight students between the ages of 17 and 25 years were tested. All the subjects were tested with the Memonum in two presentations (Black-White without attention interference, and Color with interference), with exhibition intervals of 1, 8 and 16 seconds. After each interval an auto-test format was applied to evaluate the used strategies, and the level of distraction and diffi culty generated by the test. Results: The number of successes obtained by the participants in the Memonum test was similar to that reported with the Wechsler sub-test. In addition, the increase of the exhibition intervals of the digits in the Memonum test, increased the mnemonic performance of the subject. The Color presentation had an interference effect at the attention level detected by the analyses of variability in the time dominion. Conclusion: The Memonum test is a useful tool in the evaluation of working memory as a visual test, that detects disturbances at the attention level, rendering a viable test for evaluation and diagnosis.
