Awareness of stimulus-specificity of training task
During the funnelled debriefing procedure at the end, the majority of participants (83%) reported noticing that signals were associated with pictures of food. Due to the small number of participants (17%) reporting no awareness of signal-food associations, we did not analyse how this influenced performance or food consumption. The proportion of “aware” participants was similar in both groups (Supplementary Table S1). Importantly, no participants guessed that the aim of the study was to examine the effect of stop-training on reducing subsequent food consumption. When asked directly, the majority of participants (61%) did not think that the task influenced how much they snacked afterwards, whereas 39% thought that the food images in the task made them feel hungrier and may have made them eat more. This distribution of responses did not differ significantly between groups (Supplementary Table S1).
