PULSE

Colour Recognition & Interference Test

Evaluate selective attention with an interactive Stroop-style conflict task

Test selective attention and Stroop interference by identifying colour stimuli in PULSE's browser-based colour recognition assessment.

Cognitive Conflict and Interference

This task measures selective attention and cognitive control when processing competing information streams.

In Stroop-style conflict paradigms, automated reading processes can interfere with naming font ink colors when word meaning and ink color diverge.

Assessment Structure

The test consists of 15 rounds containing a randomized mix of congruent and incongruent trials.

A prompt indicates whether to match the text meaning or the font color using five shuffled color choice buttons.

  • 15 randomized stimulus rounds
  • Dynamic matching rules (Word meaning vs Font color)
  • Shuffled response options to prevent static spatial memorization

Interference Cost and Accuracy

Scores summarize overall response latency, accuracy rates, and the interference cost representing latency differences between conflicting and congruent rounds.

Display Considerations and Scope

Screen color calibration, ambient lighting, and display contrast influence color perception. This task is an educational cognitive benchmark, not a clinical test for color vision deficiency.

Frequently Asked Questions

Why do button positions shuffle?

Shuffling button positions ensures each response requires active visual identification rather than habitual spatial motor memory.
