Cognitive effects of radiation emitted by cellular phones: The influence of exposure side and time.
Auteurs: Luria R, Eliyahu I, Hareuveny R, Margaliot M, Meiran N
Aim of study (according to author)
To examine time dependence effects of exposure to radiofrequency irradiation, emitted by GSM cellular phones, on cognitive functions of humans. The authors aimed to replicate and extend a previous study (publication 12887); especially to examine time-dependency and slowing of the left-hand response as results of the previous study.
Main outcome of study (according to author)
During the first two time blocks, the average reaction time of the right-hand responses matching condition was significantly longer under left-side exposure than under right-side exposure and sham exposure averaged together. This result confirms an effect of exposure on reaction times. Left-hand responses mismatching condition showed the same pattern, but it was non-significant. The participants failed to judge which phone was operating during the experiment.
Although the present results confirmed some findings from the previous study (e.g. time dependency of reaction times), differences between the present results and previous findings may be due to the following factors: exposure duration, responding hand, side of exposure, and differences in the cognitive tasks. These factors may have major influence on the detection of radiofrequency irradiation effects.
