We want to do a study that test if the placement of your mobile phone effects your memory. If it being next to you, decreases your memory by disturbing your attention. So the phone will either be next to you on the table, in your pocket/bag or in another room.
Is it necessary to have multiple complex tasks, such as the operation span test and another one or is that one enough?
As we are quite short on time, studying long term memory is not possible.
Thank you for your answers.
