Geophysical variables and behavior: V. Human performance in ionized air

E W Farmer, A Bendix

    Perceptual and Motor Skills
    |April 1, 1982
    PubMed
    Summary

    Exposure to high concentrations of negative air ions did not enhance human performance in reasoning, psychomotor, or memory tasks. This study found no clear evidence supporting the claim that negative ions affect cognitive or motor abilities.

    Area of Science:

    • Environmental Psychology
    • Human Performance Studies

    Background:

    • Interest exists in environmental factors influencing human cognitive and psychomotor abilities.
    • Negative air ions are proposed by some to enhance human performance.

    Purpose of the Study:

    • To investigate the claim that artificially high concentrations of negative air ions enhance human performance.
    • To assess the effect of negative air ions on reasoning, psychomotor, and memory-search tasks.

    Main Methods:

    • An experiment involving 16 subjects was conducted.
    • Subjects performed reasoning, psychomotor, and memory-search tasks.
    • Half the subjects were informed of the ion levels, controlling for expectancy effects.

    Main Results:

    • No clear evidence was obtained to support the claim of performance enhancement.
    • Confounding variables were adequately controlled during the experiment.
    • Performance on cognitive and psychomotor tasks was not demonstrably influenced by negative air ion exposure.

    Conclusions:

    • The study did not find evidence that negative air ions enhance human performance.
    • Results suggest that claims of performance enhancement due to negative air ions may not be supported by empirical data.
    • Further research may be needed to explore potential subtle effects or specific conditions.
