The effect of electromagnetic fields from digital mobile phones (DMP) on cognitive functioning is an area receiving increased attention. This study compares the performance of 120 volunteers on 8 neuropsychological tests during real or sham exposure to a DMP set to maximum permissible radiofrequency power output. When results were adjusted for known covariates (gender, age, or education), several alterations at significance levels of p<0.05 were obtained. Of these, simple and choice reaction times (CRT) showed strong evidence of impairment. Further, performance on the Trail Making Task (TMT) improved, supporting the hypothesis that DMP radiofrequency emissions improve the speed of processing of information held in working memory.
数字移动电话（DMP）产生的电磁场对认知功能的影响是一个日益受到关注的领域。本研究比较了120名志愿者在实际暴露或假暴露于设置为最大允许射频功率输出的DMP时，在8项神经心理学测试中的表现。当对已知协变量（性别、年龄或教育程度）进行结果调整后，在p<0.05的显著性水平上获得了一些变化。其中，简单反应时和选择反应时（CRT）显示出明显的受损证据。此外，连线测验（TMT）的表现有所改善，支持了DMP射频辐射可提高工作记忆中信息处理速度的假设。
