As was the case of the initial adoption of past technologies for educational purposes in schools and in homes, there is little formalized direction regarding the use of these devices – questions such as which tablet computers are most appropriate for which setting; which applications (software programs running on the tablet computers) best lead to preferred outcomes; or how to teach users to operate tablet computers - remain unanswered. Trial-and-error predominates and users base choices regarding devices and applications from their personal interests in a particular topic, cost (where free applications are especially attractive), word of mouth, or as a result of marketing efforts on- and off-line. Since users and particularly young users are often left to engage with the devices in a non-directed manner, we replicate this practice of non-directed user engagement with tablets in our study design as we investigate the effect of using these devices on cognition. Thus, our study involved not instructing participants on how to interact with the applications during tablet computer use.
