The participants performed four testing sessions (at least one week apart from each other): a) baseline measurement before exposure, b) exposure to GSM, c) exposure to UMTS and d) sham exposure. Cognitive functioning was measured using a digit symbol substitution test (given a table displaying the correspondence between pairs of digits [from 1 to 9] and symbols, subjects have to fill in blank squares with the symbol that is paired with the digit displayed above the square; subjects have to fill in as many squares as possible in 90 sec), a digit span test and mental arithmetic tasks (5 sec to complete addition and subtraction equations; 187 trials).
