[Effects of caffeine on physiological parameters during a learning test]

J M Feierabend, K Bättig

    |October 1, 1982
    PubMed
    Summary

    Caffeine intake (300 mg) increased finger vasoconstriction in men but did not impact conceptual learning. Performance variance decreased in a cancellation task after caffeine consumption.

    Area of Science:

    • Physiology
    • Cognitive Science
    • Pharmacology

    Context:

    • Investigating the physiological and cognitive effects of caffeine.
    • Utilizing a conceptual learning paradigm with 48 male participants.
    • Comparing caffeine's effects against placebo (decaffeinated coffee, warm water, no beverage).

    Purpose:

    • To determine if 300 mg of caffeine affects physiological variables and conceptual learning.
    • To identify specific physiological markers influenced by caffeine administration.
    • To assess caffeine's impact on cognitive task performance variance.

    Summary:

    • Oral administration of 300 mg caffeine in decaffeinated coffee resulted in increased index finger vasoconstriction in men.
    • Physiological variables like R-R interval, respiration, skin conductance, and electromyography did not differentiate caffeine from control groups.
    • Caffeine did not alter conceptual learning but reduced performance variance in a continuous letter cancellation task.

    Impact:

    • Highlights vasoconstriction as a specific physiological response to moderate caffeine doses.
    • Suggests caffeine's primary impact may be on performance consistency rather than learning itself.
    • Provides insights into caffeine's nuanced effects on human physiology and cognitive performance.
