Earlier research has demonstrated that food-specific inhibition training wherein food cues are repeatedly and consistently mapped onto stop signals decreases food intake and bodyweight. The mechanisms underlying these training effects, however, remain unclear. It has been suggested that consistently pairing stimuli with stop signals induces automatic stop associations with those stimuli, thereby facilitating automatic, bottom-up inhibition. This study examined this hypothesis with respect to food-inhibition training. Participants performed a training that consistently paired chocolate with no go cues (chocolate/no-go) or with go cues (chocolate/go). Following training, we measured automatic associations between chocolate and stop versus go, as well as food intake and desire to eat. As expected, food that was consistently mapped onto stopping was indeed more associated with stopping versus going afterwards. In replication of previous results, participants in the no-go condition also showed less desire to eat and reduced food intake relative to the go condition. Together these findings support the idea that food-specific inhibition training prompts the development of automatic inhibition associations, which subsequently facilitate inhibitory control over unwanted food-related urges.
早期研究表明，食物特定的抑制训练，即食物线索被反复且一致地映射到停止信号上，可以减少食物摄入和体重。然而，这些训练效果的机制仍不清楚。有人认为，将刺激物与停止信号一致配对会导致与这些刺激物自动建立停止关联，从而促进自动、自下而上的抑制。本研究针对食物抑制训练检验了这一假设。参与者进行了一项训练，该训练将巧克力与不能去的线索（巧克力/不能去）或去的线索（巧克力/去）一致地配对。在训练后，我们测量了巧克力与停止与去之间的自动关联，以及食物摄入和想吃的欲望。正如预期的那样，食物与停止而不是去的线索一致地映射后，确实更相关。与之前的结果一致，不能去条件下的参与者也表现出比去条件下更低的食欲和减少的食物摄入。这些发现共同支持了这样一种观点，即食物特定的抑制训练促使自动抑制关联的发展，从而促进对不必要的食物相关冲动的抑制控制。
