Cognitive Load
CONCEPT
EXPERIENCE DESIGN
Cognitive load describes how much working memory an interface demands; reducing unnecessary load helps users finish tasks faster and with fewer errors.

Neuromarketing
The use of neuroscience or physiological measurement methods to study responses relevant to marketing and consumer behavior.
BUSINESS RELEVANCE
Neuromarketing can reveal attention and emotional responses that people do not report in surveys, which helps compare ad creatives, packaging or interfaces before spending on a full launch.
IMPLEMENTATION EXAMPLE
A brand tests 4 video ad cuts with 40 participants using eye tracking and galvanic skin response, finds that the logo is missed in 2 versions, and moves the brand cue into the first 3 seconds before media buying.
LIMITATIONS
Lab samples are small and settings are artificial, so results may not predict real purchase behavior. Physiological signals are hard to interpret, findings are often overstated, and collecting biometric data raises consent and privacy duties.
TECHNICAL EXPLANATION
Neuromarketing uses methods such as EEG for electrical brain activity, fMRI for blood-flow changes, eye tracking for gaze and fixation, and galvanic skin response or heart rate for arousal. Facial coding and implicit association tests are also used as indirect measures. Signals are recorded while participants view stimuli, synchronized with the content timeline, and compared across variants or against self-reported responses.
