Attentional bias (AB) for palatable foods has been linked to overeating, yet data on its modulation with body-mass index (BMI) and hunger/satiety are inconsistent. We tested whether hunger, sensory-specific satiety and BMI interact to shape automatic capture of attention by real high-calorie foods. Two emotional-attentional-blink (EAB) experiments presented food distractors either 300 ms (lag-3) or 900 ms (lag-9) before a neutral target.
Experiment 1 (N = 183; whole BMI range) randomly assigned participants to taste (non-satiated), satiated or non-eating conditions; the snacks eaten (or not eaten) subsequently re-appeared as distractors in the EAB task. Experiment 2 (N = 61; 31 overweight/obese, 30 normal-weight) manipulated hunger/satiety states and snack type (consumed vs. novel) orthogonally, in a double session design. Experiment 1—food images presented at lag-3 reduced target detection compared with lag-9 (OR = 0.61, CI 0.50–0.75, p
