Appearance‐Related Communication Mediates the Link Between Self‐Objectification and Health and Well‐Being Outcomes

Grounded in objectification theory, the 2 studies presented here predicted that self‐objectification is positively related to appearance‐related communication (i.e., fat talk and old talk), and, in turn, appearance‐related communication is associated with health and well‐being outcomes. Results from Study 1, which investigated only fat talk, revealed that fat talk significantly mediated the relationship between self‐objectification and body dissatisfaction, drive for thinness, bulimia, and self‐esteem. Study 2 sought to replicate the findings from Study 1, as well as extend appearance‐related communication to old talk. Fat talk was found to mediate the relationships between self‐objectification and body dissatisfaction, drive for thinness, bulimia, depression, and diet. Old talk significantly mediated the relationships between body dissatisfaction, drive for thinness, and bulimia.     

Role of the area postrema in three putative measures of motion sickness in the rat

After thermal cauterization of the area postrema in rats the absence of conditioned taste aversion to sucrose paired with lithium chloride (0.15 M, 3.3 ml/kg) was used as a pharmacologic/behavioral index of area postrema damage. In a subsequent experiment the effects of area postrema lesions on three measures proposed as species-relevant measures of motion sickness were studied, using off-vertical rotation at 150 degrees/s for either 30 or 90 min. Lesions of area postrema did not alter postrotational suppression of drinking or amount of defecation during motion. The initial acquisition of conditioned taste aversion to a novel cider vinegar solution paired with motion was not affected by lesioning of the area postrema, but these taste aversions extinguished more slowly in lesioned rats than in sham-operates or intact controls. Results are discussed in terms of proposed humoral factors which may induce motion sickness and in light of recent data on the role of the area postrema in similar measures in species possessing the complete emetic reflex.
