Computerized cognitive assessment in the elderly is receiving increasing interest as it is easily accessible, reliable regarding the collection of data and allows precise evaluation of reaction time (Schatz and Browndyke 2002, Zygouris and Tsolaki 2015). This level of precision is particularly pertinent in the evaluation of executive functions, such as, updating, inhibition, alternating and divided attention (Miyake and Friedman 2012). Divided attention, for example, refers to the ability to perform two tasks simultaneously and is associated with a higher risk of motor vehicle accidents and falls or collisions while walking and talking in older populations (Broman et al. 2004, Chaparro, Wood, and Carberry 2005, Clay et al. 2005; Kramer and Madden 2008; Verghese et al. 2002). This function is challenging to evaluate due to biases through paper and pencil tests (Baddeley and Delia Sala, 1996) and several studies have used computerized tasks to better isolate divided attention (Bherer et al. 2008, Kramer, Larish, and Strayer, 1995, Lussier, Gagnon, and Bherer 2012).
