Mobile phone radiation showed no cognitive effects in this analysis, but industry-funded studies were biased toward finding no harm.

Plain English Summary

Summary written for general audiences

Italian researchers analyzed 24 studies to determine if mobile phone radiation affects thinking skills and reaction times. Their meta-analysis found no significant cognitive or psychomotor effects from mobile phone-like electromagnetic fields. However, they discovered that studies funded by the wireless industry were more likely to show no effects, while studies with mixed funding sources sometimes found small impacts on working memory tasks.

Study Details

The aim of this study is to investigate systematic review and meta-analysis of psychomotor effects of mobile phone electromagnetic fields.

Only three tasks (2-back, 3-back and simple reaction time (SRT)) displayed significant heterogeneity...

Mobile phone-like EMF do not seem to induce cognitive and psychomotor effects. Nonetheless, the existence of sponsorship and publication biases should encourage WHO intervention to develop official research standards and guidelines. In addition, future research should address critical and neglected issues such as investigation of repeated, intensive and chronic exposures, especially in highly sensitive populations such as children.
