To examine the effect of electromagnetic fields emitted by mobile phones on human attention by investigating the relationship between the duration of irradiation and the effect of electromagnetic field.
Modulation type: pulsed
Exposure duration: continuous for 25 min
|Exposure duration||continuous for 25 min|
No parameters are specified for this exposure.
Subjects in the experimental group appear to become somewhat faster than subjects in the control group in responding to the SART after being exposed to the electromagnetic field. Yet, there were no significant differences in the number of correct responses on the SART, indicating that there was no observable change in the quality of performance of the subjects. The absence of significant difference on the scores on the TMT may suggest that an increased duration of irradiation may have a differential impact on different human attention functions, or it might relate to the possibility that the effect on the performance in the TMT tests might take longer times for it to be noticeable. The data seem to suggest that attention functions may be differentially enhanced with an increased duration of exposure to the electromagnetic field. Furthermore, this transient facilitation effect might be dose dependent.
