Mobile phone

Mobile phone is a measure of auditory sequential memory involving digit span, containing two parts. For the first part, the student is given a sequence of digits (a telephone number) to remember, which they then enter onto a mobile phone in the same order. Students must get both practice items (two-digit sequences) correct before moving on to the test items. All students start with two trials of two-digit sequences and if they answer one or both correctly then they move on to two trials of three-digit sequences and so on up to nine digits. If a student fails both trials within a level, then this part of the test is discontinued. For the second part, the student is required to enter the digits in reverse order. Again, they start with two trials of two-digit sequences and if they answer one or both correctly then they move on to two trials of three- digit sequences and so on up to seven digits. If a student fails both trials within a level, then the subtest is discontinued.
