我们研究了食物剥夺对食物和非食物物体的口腔和手动触觉大小感知的影响。根据相关理论（需求比例感知、动机感知、挫折性非奖赏、感知防御和感官敏感），至少可以得出四种完全不同的相互竞争的预测。测试这些预测，我们发现在四个实验中，参与者估计的非食物和食物对象的长度在饥饿时比饱腹时更大，这只适用于口头触觉感知，而手动触觉感知不受饥饿状态的影响。主观报告的饥饿与估计的对象大小在口头上，但不是在手动，触觉感知呈正相关。食物剥夺对口腔知觉的影响消失后，口腔刺激，即使是饥饿的人。这些结果有利于感觉敏化帐户保持饥饿本身并不改变口腔知觉，但伴随着缺乏口腔粘膜的感觉刺激。口头和手动触觉感知往往低估实际物体的大小。最后，增强效果的域目标匹配被发现，即食物对象感知较大的口头比手动触觉，而非食物对象感知较大的手动比口头触觉。
We investigated the impact of food deprivation on oral and manual haptic size perception of food and non-food objects. From relevant theories (need-proportional perception, motivated perception, frustrative nonreward, perceptual defence, and sensory sensitisation) at least four completely different competing predictions can be derived. Testing these predictions, we found across four experiments that participants estimated the length of both non-food and food objects to be larger when hungry than when satiated, which was true only for oral haptic perception, while manual haptic perception was not influenced by hunger state. Subjectively reported hunger correlated positively with estimated object size in oral, but not in manual, haptic perception. The impact of food deprivation on oral perception vanished after oral stimulations even for hungry individuals. These results favour a sensory sensitisation account maintaining that hunger itself does not alter oral perception but the accompanying lack of sensory stimulation of the oral mucosa. Both oral and manual haptic perception tended to underestimate actual object size. Finally, an enhancing effect of domain-target matching was found, ie food objects were perceived larger by oral than by manual haptics, while non-food objects were perceived larger by manual than by oral haptics.
