Eating under distracted conditions such as viewing television is associated with overeating and weight gain. Following evidence from earlier findings, in this issue Hoffman-Hensel et al. report a study in which they investigated the influence of distraction on intensity perception of low and high caloric food odors and neural responses to these food odors. Their findings suggest that distraction directly leads to decreased neural response in olfactory cortex and decreased intensity, and, indirectly to overeating, through a mechanism that then compensates for the decrease in strength of the olfactory signals. I discuss these results in a broader context of attention to odors.
在分散注意力的情况下进食，例如看电视，与暴饮暴食和体重增加有关。基于早期研究结果，在本期中，Hoffman-Hensel 等人报告了一项研究，该研究调查了分心对低热量和高热量食物气味感知强度的影响，以及这些食物气味的神经反应。他们的研究结果表明，分心会直接导致嗅觉皮层的神经反应减弱，食物气味的感知强度降低，进而通过一种补偿嗅觉信号强度减弱的机制导致暴饮暴食。我在更广泛的注意力与气味的背景下讨论了这些结果。
