Cue reactivity to food- and body-related stimuli in restrained and unrestrained eaters.
In the present study, psychophysiological cue reactivity was monitored in 11 restrained (nonclinical but disinhibitive) and 13 unrestrained (control) subjects. The cues consisted of slides depicting either personally "favourite" binge food items or the subject's own body. The parameters monitored included skin conductance, heart rate, startle eyeblink EMG, and facial (corrugator and zygomatic) EMG. Although for several parameters the expected main effect of slide type was found, no between-group differences in cue reactivity could be demonstrated. Several explanations of the present finding, as well as possible future directions for cue reactivity research, are discussed, with emphasis placed upon the role of classical conditioning in eating disorders.
