Cognitive effects from cellular phones persisted even when RF radiation was drastically reduced, suggesting non-RF factors may be responsible.

Plain English Summary

Summary written for general audiences

Researchers tested 29 right-handed men with phones on both sides of the head during a spatial working memory task. External antennas were used to prevent RF radiation from the phones' internal antennas. Despite drastically reduced RF exposure, results were similar to earlier studies where phones emitted RF radiation. The authors conclude that some effects previously linked to RF radiation may come from other factors.

Why This Matters

The study aimed to test whether non-radiofrequency factors could explain cognitive effects seen with cellular phones. Earlier work by the same group had found that experiment duration and which side of the head the phone was on influenced whether effects were detected. Other research had reported that cognitive functions may change during exposure to radiofrequency radiation from phones.

Study Details

The aim of this study is to investigate Cognitive effects of cellular phones: a possible role of non-radiofrequency radiation factors.

In this brief follow-up experiment, 29 right-handed male subjects were divided into two groups. Each...

Contrary to our previous studies, in this work external antennas located far away from the subjects ...

These results indicate that some of the effects previously attributed to RFR can be the result of some confounders.

Quick Questions About This Study

Twenty-nine right-handed men had phones on both sides of the head and performed a spatial working memory task with left-hand or right-hand responses.
External antennas far from the subjects were connected to the phones, preventing emission from the internal antennas.
Results were similar to earlier studies despite drastically reduced RF exposure, suggesting non-RF factors may explain some effects.
Experiment duration and which side of the head the phone was on influenced detection of cognitive effects.
To investigate whether non-radiofrequency radiation factors could play a role in cognitive effects of cellular phones.
