Use: Natural scenarios like "Choose a product you like" to capture authentic gaze behavior. Overly Complex Tasks Avoid: "Evaluate the ergonomics, color scheme, and brand alignment" – causes cognitive overload. Use: Simple actions: "Find the shipping information on this website." Ignoring Context Avoid: Testing stimuli in isolation (e.g., a single ad on a blank screen). Use: Real-world environments (e.g., a shelf with competitors or a webpage with navigation). Unrealistic Time Frames Avoid: Unlimited viewing time. Use: Time constraints matching real behavior (e.g., "You have 10 seconds to scan this banner"). Order Bias Avoid: All participants viewing stimuli in the same sequence. Use: Randomized presentation to counterbalance fatigue and primacy effects. Artificial Prompts Avoid: "Pay attention to the discount text" – creates demand characteristics. Use: Implicit tasks: "Decide if you would buy this product." Key Principle: Tasks should replicate natural behavior, not test obedience to instructions. The goal is to measure unconscious attention, not guided perception. Neuromarketing Research
