DESCRIPTION (provided by applicant): There has been much speculation that individuals who evidence eating pathology have impairments in emotional processing and emotion regulation (e.g., Mountford, 2004; Vervaet et al., 2003). Despite the critical role emotions are thought to play in the etiology and maintenance of eating pathology there has been relatively little empirical work conducted in this area. The purpose of the proposed study is to further understand emotional impairments in women with eating pathology by studying emotional reactivity and regulation in response to affect eliciting pictures (pleasant, unpleasant and neutral) in women with primarily anorexic-type symptoms (restrictors), primarily bulimic symptoms , and controls using psychophysiological and subjective indices of emotional response. It is hypothesized that both restrictor and bulimic participants will show greater physiological reactivity to the pleasant and unpleasant pictures compared to the control participants, and the pattern of heightened reactivity will continue to be displayed among these two groups after picture offset, consistent with emotion dysregulation. In addition, it is expected that restrictor participants will report diminished self-reported emotion relative to the bulimic and control participants.

描述（由申请人提供）：有很多猜测认为，有饮食病理学证据的个体在情绪处理和情绪调节方面存在缺陷（例如，Mountford，2004；Vervaet 等，2003）。尽管情绪被认为在饮食病理学的病因学和维持中发挥着关键作用，但在该领域进行的实证工作相对较少。拟议研究的目的是通过研究主要患有厌食型症状（限制性因素）（主要是暴食症）的女性对影响引发的画面（愉快、不愉快和中性）的情绪反应和调节，进一步了解患有饮食病理学的女性的情绪障碍症状，并使用情绪反应的心理生理学和主观指标进行控制。据推测，与对照组参与者相比，限制者和贪食症参与者都会对愉快和不愉快的图片表现出更大的生理反应，并且在图片偏移后，这两组人将继续表现出增强的反应模式，这与情绪失调一致。此外，预计限制者参与者相对于暴食症和控制参与者来说，自我报告的情绪会减弱。
