Impulsivity, caffeine, and proofreading: a test of the Easterbrook hypothesis.

K J Anderson, W Revelle

Journal of Experimental Psychology. Human Perception and Performance

|August 1, 1982

Summary

High arousal, induced by caffeine, impaired error detection in less impulsive individuals but improved it in more impulsive subjects. This suggests arousal directly impacts simultaneous information processing capacity.

Area of Science:

Cognitive Psychology
Neuroscience
Human Performance

Background:

The Easterbrook hypothesis posits an inverse relationship between arousal and cue utilization.
This hypothesis is often used to explain the arousal-performance curve but lacks empirical support.
Investigating the direct impact of arousal on information processing is crucial.

Purpose of the Study:

To empirically test the Easterbrook hypothesis regarding arousal and cue utilization.
To examine the effects of caffeine-induced arousal on error detection sensitivity.
To explore the interaction between individual impulsivity levels and arousal on cognitive performance.

Main Methods:

Sixty undergraduates varying in impulsivity were administered caffeine or a placebo.

Related Experiment Videos

Participants proofread passages to assess error detection.

Signal detection techniques were employed to calculate sensitivity estimates.

Main Results:

A significant crossover interaction was observed between impulsivity and drug condition for interword errors.
Caffeine enhanced error detection in more impulsive (less aroused) subjects.
Caffeine reduced error detection in less impulsive (more aroused) subjects.

Conclusions:

The findings support the notion that arousal directly affects simultaneous information processing capacity.
Arousal's impact on information processing appears independent of performance speed.
Individual differences in impulsivity modulate the effects of arousal on cognitive tasks.
