Hi,

There are several articles and sources on measuring customer satisfaction or brand loyalty through neuroimaging, specifically EEG. Here are some suggestions:

• A systematic review of the prediction of consumer preference using EEG measures and machine-learning in neuromarketing research
• Measuring brand association strength with EEG: A single-trial N400 ERP study
• Neuromarketing Tools Used in the Marketing Mix: A Systematic Literature and Future Research Agenda
• Recognition of Consumer Preference by Analysis and Classification EEG Signals
• Is EEG Suitable for Marketing Research? A Systematic Review

These sources provide insights into how EEG measures can be used to measure customer satisfaction or brand loyalty in neuromarketing research.

Hope this helps.

Good afternoon dear Hsin-Yuan Chen
