Using eye movements in the dot-probe paradigm to investigate attention bias in illness anxiety disorder

Figure 1 Experimental setup for capturing eye-movement data.

Figure 2 Disease–neutral picture, disease–positive picture, and disease–threat picture presentation examples. A: Disease–neutral (e.g., oral surgery vs rail); B: Disease–positive (e.g., infusion vs scenery); and C: Disease–threat (e.g., operating room vs traffic).
