Summary

The Stroop effect is typically measured incorrectly. New analysis reveals a multiplicative process, suggesting ratios, not differences, are the appropriate measure for Stroop facilitation and interference.

Area of Science:

  • Cognitive Psychology
  • Psycholinguistics

Background:

  • The Stroop color-naming task measures facilitation and interference effects.
  • Current measurement relies on differences between naming times (congruent/conflicting vs. neutral).
  • This assumes a linear relationship with a slope of one and a non-zero intercept.

Purpose of the Study:

  • To re-evaluate the measurement of Stroop facilitation and interference effects.
  • To investigate the underlying mathematical process of the Stroop effect.
  • To propose a more accurate method for quantifying Stroop effects.

Main Methods:

  • Analysis of regression functions relating naming times.
  • Comparison of observed regression slopes and intercepts to theoretical assumptions.
  • Examination of the multiplicative nature of cognitive processes.

Main Results:

  • The regression function for Stroop facilitation has a slope less than one and a zero intercept.
  • The regression function for Stroop interference has a slope greater than one and a zero intercept.
  • These findings contradict the linear model assumption.

Conclusions:

  • Stroop facilitation and interference effects result from a multiplicative process.
  • Each naming stage is proportionally adjusted.
  • The ratio of naming times (congruent/conflicting over neutral) is a more appropriate measure.
