There is considerable evidence that body image is an elastic construct, which can be influenced by environmental and internal factors. The present study used a visual subliminal processing paradigm, with the aim of determining the impact of preconscious processing of verbal cues upon body image (percept and concept).
Forty nonclinical women completed measures of body percept and concept before and after being exposed to very rapid presentations (4 ms) of fatness and thinness cues.
The women with relatively unhealthy eating attitudes were influenced by the fatness stimulus, with a worsening of their body percept and concept. In contrast, the women with healthier eating attitudes showed an improvement in their body percept in response to the thinness stimulus.
The findings support the centrality of body image schemata in eating psychopathology, although there is a need for replication and extension in other groups.
有大量证据表明身体意象是一个具有弹性的概念,会受到环境和内在因素的影响。本研究采用视觉阈下加工范式,旨在确定言语线索的前意识加工对身体意象(感知和概念)的影响。
40名非临床女性在暴露于极快速呈现(4毫秒)的胖瘦线索之前和之后,完成了身体感知和概念的测量。
饮食态度相对不健康的女性受到肥胖刺激的影响,其身体感知和概念变差。相比之下,饮食态度更健康的女性在受到瘦的刺激后,身体感知得到改善。
这些发现支持了身体意象图式在饮食心理病理学中的核心地位,尽管需要在其他群体中进行重复和扩展研究。
