Incidental Findings, Visual Attention
Brief Title: Project 4 Example: Mixed Hybrid Checklist
In "Mixed Hybrid Search", participants look for 3 specific target (e.g. this boot, this cat, this hat) and 3 categorical items (ANY fruit, ANY car, ANY game). In this task, participants tend to miss many categorical items.
