The study compares visual evaluation of an amount of food and an amount of nonedible objects in patients affected by Anorexia Nervosa and control subjects.
59 anorexic subjects were asked to evaluate an amount of candies and plastic bricks shown to them. Their answers were compared to both the real number of objects and the parallel evaluations given by 56 control subjects.
There were no significant differences in stimuli evaluation between patients affected by AN and control subjects. Both groups reported a significantly lower number of both candies and bricks in comparison to their real number.
In an experimental condition not related with food intake there is the same under-evaluation of the amount of presented food and nonedible objects among patients affected by AN and Control Subjects. The clinical finding of overestimation of food intake among patients affected by AN seems not to be due to a perceptive bias.
本研究比较神经性厌食症患者与对照受试者对食物量和非食用物品量的视觉评估。
要求59名厌食症受试者评估向他们展示的糖果和塑料积木的数量。将他们的答案与物品的实际数量以及56名对照受试者的平行评估进行比较。
神经性厌食症患者与对照受试者在刺激评估方面没有显著差异。与实际数量相比，两组报告的糖果和积木数量均显著更低。
在与食物摄入无关的实验条件下，神经性厌食症患者和对照受试者对所呈现食物和非食用物品量的低估程度相同。神经性厌食症患者高估食物摄入量的临床发现似乎并非由于感知偏差。
