Recent research has indicated that craving for food can be elicited by exposure to food cues, suggesting that exposure to food cues may represent a useful experimental paradigm to investigate mechanisms related to binge eating. The first objective of the present research was to replicate previous reports that exposure to food cues elicits craving for food.(More)
Recent biological conceptualizations of craving and addiction have implicated mesolimbic dopamine activity as a central feature of the process of addiction. Imaging, and pharmacological studies have supported a role for dopaminergic structures in cue-elicited craving for tobacco. If mesolimbic dopamine activity is associated with cue-elicited craving for(More)
OBJECTIVE We examined the etiology of two disordered eating characteristics. METHOD Participants included 1,470 female adolescent and young adult twins and their female nontwin siblings. Phenotypic factor analyses of a seven-item eating pathology screening tool yielded two factors: weight and shape concerns and behaviors (WSCB) and binge eating (BE).(More)

However, most studies have focused on a single polymorphism (5-HTTLPR) in SLC6A4; little research has utilized multiple single nucleotide polymorphisms (SNPs) to(More)
