PSD of food/control stimuli for tasks A and B. (A) For task A, there was a significantly greater PSD in response to the food images (“F”) in fasting than in satiety (*p < 0.02), while no significant difference was found for the control images (“C”) between fasting and satiety conditions. Additionally, the PSD in fasting was significantly greater for the food images (“F”) than for control images (“C”) (*p < 0.03). (B) For task B, there was a significantly smaller PSD in response to the food images (“F”) in fasting than in satiety (**p < 0.01), while no significant difference was found for the control images (“C”) between fasting and satiety conditions. The PSD in fasting was significantly smaller for the food images (“F”) than for control images (“C”) (**p < 0.01). Error bars represent mean ± sem.
