Weight differences in emotional responsiveness to proprioceptive and pictorial stimuli.

Two studies were conducted to investigate weight differences in emotional responsiveness to proprioceptive and pictorial stimuli. Contrary to past evidence that overweight persons are more emotional than normals, the emotional state of normal-weight subjects fluctuated with manipulations of their facial expression, whereas that of overweight subjects did not respond to these proprioceptive cues. Furthermore, whereas past research employing affectively loaded pictures had found overweight persons to be more emotionally responsive than normals to these external stimuli, no weight differences were obtained in the present studies, which employed less polarized pictures. Implications of these findings for generalizations about weight differences in emotionality are discussed.
