Abstract
Objective: This study examined sensory and cognitive processing in adolescents, young adults and older adults, when exposed to 2nd (2G) and 3rd (3G) generation mobile phone signals. Methods: Tests employed were the auditory 3-stimulus oddball and the N-back. Forty-one 13-15. year olds, forty-two 19-40. year olds and twenty 55-70. year olds were tested using a double-blind cross-over design, where each participant received Sham, 2G and 3G exposures, separated by at least 4. days. Results: 3-Stimulus oddball task: Behavioural: accuracy and reaction time of responses to targets were not affected by exposure. Electrophysiological: augmented N1 was found in the 2G condition (independent of age group). N-back task: Behavioural: the combined groups performed less accurately during the 3G exposure (compared to Sham), with post hoc tests finding this effect separately in the adolescents only. Electrophysiological: delayed ERD/ERS responses of the alpha power were found in both 3G and 2G conditions (compared to Sham; independent of age group). Conclusion: Employing tasks tailored to each individual's ability level, this study provides support for an effect of acute 2G and 3G exposure on human cognitive function. Significance: The subtlety of mobile phone effect on cognition in our study suggests that it is important to account for individual differences in future mobile phone research. © 2011 International Federation of Clinical Neurophysiology.
