“…Bodyshape-related stimuli (e.g., referring to thinness vs. fatness) have therefore been used in a wide range of body-image studies focusing on the effects of exposure to societal appearance norms (for a meta-analysis, see Hausenblas et al, 2013), attentional biases (e.g., Gao et al, 2013;Glauert, Rhodes, Fink, & Grammer, 2010), implicitly or explicitly assessed attitudes/ judgments toward body shapes/weights (e.g., Ahern, Bennett, & Hetherington, 2008;Fan, Liu, Wu, & Dai, 2004), body size estimation (e.g., Docteur, Urdapilleta, & Rico Duarte, 2012), Electronic supplementary material The online version of this article (doi:10.3758/s13428-016-0703-7) contains supplementary material, which is available to authorized users. and memory biases (e.g., Gasperini & Rousseau, 2014). However, the variety of stimuli used (e.g., words, pictures downloaded from the Internet, computer-generated pictures, schematic/drawn figures, or pictures of participants) has made the results of studies with similar objectives difficult to compare.…”

The body-shape-related stimuli used in most bodyimage studies have several limitations (e.g., a lack of pilot validation procedures and the use of non-body-shape-related control/neutral stimuli). We therefore developed a database of 61 computer-generated body-only pictures of women, wherein bodies were methodically manipulated in terms of fatness versus thinness. Eighty-two young women assessed the pictures' attractiveness, beauty, harmony (valence ratings), and body shape (assessed on a thinness/fatness axis), providing normative data for valence and body shape ratings. First, stimuli manipulated for fatness versus thinness conveyed comparable emotional intensities regarding the valence and body shape ratings. Second, different subcategories of stimuli were obtained on the basis of variations in body shape and valence judgments. Fat and thin bodies were distributed into several subcategories depending on their valence ratings, and a subcategory containing stimuli that were neutral in terms of valence and body shape was identified. Interestingly, at a descriptive level, the thinness/fatness manipulations of the bodies were in a curvilinear relationship with the valence ratings: Thin bodies were not only judged as positive, but also as negative when their estimated body mass indexes (BMIs) decreased too much. Finally, convergent validity was assessed by exploring the impacts of body-image-related variables (BMI, thin-ideal internalization, and body dissatisfaction) on participants' judgments of the bodies. Valence judgments, but not body shape judgments, were influenced by the participants' levels of thin-ideal internalization and body dissatisfaction. Participants' BMIs did not significantly influence their judgments. Given these findings, this database contains relevant material that can be used in various fields, primarily for studies of body-image disturbance or eating disorders.
