An Investigation into the Stroop Effect

By Fiona Taylor

Introduction

Stroop conducted experiments in the 1930s on interference with visual perception. He discovered that participants had difficulties naming colours when they were printed in different coloured inks.

In some lists, colour words were spelled and printed in the same ink colours (congruous).

Example: RED

In other lists the words and colours did not match (incongruous).

Example: GREEN

Participants in Stroop's experiments took longer to name the incongruous words. He called this the 'Stroop effect'.

Aim

To investigate the Stroop effect by conducting an experiment to time how long it takes for participants to say the colours of the words on two different lists (congruent/incongruent). To then produce evidence in the form of graphs and data analysis to support or disprove the following hypothesis.

Hypothesis

The average mean time to complete list two (incongruous) will be greater than the average mean time to complete list one (congruous).

IV - lists of words congruent/incongruent

DV - time taken to name ink colours measured in seconds

Design

As quantitative data (time) is being measured, the experiment should
