Stroop Effect Demonstration: Plan the Conditions and Debrief the Result
Plan a paper color-naming demonstration with condition and order sheets, blank timing and error records, an observer option and a bounded debrief.

Perception & Cognition
Sensation, perception and cognition offer different ways to examine an everyday experience. This guide helps you distinguish incoming sensory information, its interpretation and the processes involved in attention and thinking.
Begin with sensation and perception
Sensation concerns the detection of physical stimuli through sensory systems. Perception concerns how sensory information is organized and interpreted. The distinction matters when describing an illusion: an unusual experience does not by itself show that a sensory organ is malfunctioning. Consider the stimulus, the surrounding context and what the observer was asked to do.
Ask what the task demands
An attention or cognition demonstration can involve several processes at once. For a Stroop-style task, distinguish reading a word from naming a color. Compare instructions and response requirements before interpreting any difference. Use an example to discuss a hypothesis rather than presenting a single person’s timing as a measure of intelligence or ability.
Keep interpretations modest
Perception activities can illustrate a concept without proving that everyone experiences it in the same way. Accessibility, prior knowledge, language and instructions can affect a classroom task. Offer a paper explanation or observer role, and avoid asking students to reveal a diagnosis or explain a sensory difference in public. Record the limits alongside the observation.
