These thought patterns could then lead to behaviours that could lead to the development of BN, like dieting or restricted eating. Which, in turn, could lead to bingeing and purging.<\/span><\/p>\n<blockquote><p><span style=\"font-weight:400\">When analysing cognitive etiologies, it\u2019s imperative that one continually asks the questions, \u2018<\/span><i><span style=\"font-weight:400\">what could be influencing the development of these thought patterns?\u2019 <\/span><\/i><span style=\"font-weight:400\">And<\/span><i><span style=\"font-weight:400\"> \u2018how could these thoughts lead to BN symptoms?\u2019<\/span><\/i><span style=\"font-weight:400\"> That is to say, if an individual has an idealization of thinness, it\u2019s important to consider how this may have developed.

Using body silhouettes (fig. 1), they were asked to identify:<\/span><\/p>\n<ul>\n<li><span style=\"font-weight:400\"> their ideal figure<\/span><\/li>\n<li><span style=\"font-weight:400\"> their current figurse<\/span><\/li>\n<li><span style=\"font-weight:400\"> what they thought the opposite sex thought was the most attractive. <\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight:400\">Body dissatisfaction can be measured by analysing the difference between the \u201cideal\u201d and \u201ccurrent\u201d ratings, as well as between what the opposite sex found attractive and the \u201ccurrent\u201d figure.<\/span><\/p>\n<div id=\"attachment_10799\" style=\"width: 310px\" class=\"wp-caption alignright\"><img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-10799\" class=\"alignnone size-medium wp-image-10799\" src=\"https:\/\/i0.wp.com\/blogs.themantic-education.com\/ibpsych\/wp-content\/uploads\/sites\/3\/2018\/05\/stunkards-visual-figures-scale.png?resize=300%2C184&#038;ssl=1\" alt=\"Stunkards-Visual-Figures-Scale\" width=\"300\" height=\"184\" srcset=\"https:\/\/i0.wp.com\/www.themantic-education.com\/ibpsych\/wp-content\/uploads\/sites\/3\/2018\/05\/stunkards-visual-figures-scale.png?w=850&amp;ssl=1 850w, https:\/\/i0.wp.com\/www.themantic-education.com\/ibpsych\/wp-content\/uploads\/sites\/3\/2018\/05\/stunkards-visual-figures-scale.png?resize=300%2C184&amp;ssl=1 300w, https:\/\/i0.wp.com\/www.themantic-education.com\/ibpsych\/wp-content\/uploads\/sites\/3\/2018\/05\/stunkards-visual-figures-scale.png?resize=768%2C471&amp;ssl=1 768w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><p id=\"caption-attachment-10799\" class=\"wp-caption-text\">Fig 1. This is the type of image researchers use to study perceptions of body shapes and body dissatisfaction.<\/p><\/div>\n<p><span style=\"font-weight:400\">The results of this study showed that males chose similar silhouettes for all three. The females, however, selected \u201ccurrent\u201d body shape silhouettes that were heavier than their ideal and were heavier than what they thought men would want. <\/span><\/p>\n<p><b>Replicated Research (Methods and Results) <\/b><\/p>\n<p><span style=\"font-weight:400\">In a follow-up study, published in 1988, Rozin and Fallon used similar methodology, but this time they included data from their student participants\u2019 parents. Students were recruited from first year university courses.In order for the data to be included, the son\/daughter (college aged participant) had to have both biological parents alive and still living together and had to have spent most of their pre-college years living with both parents.<\/span><\/p>\n<blockquote><p><em><span style=\"font-weight:400\"><strong>Possible details for evaluation:\u00a0<\/strong>97 families participated in the follow-up study; there were 55 daughters, and 42 sons. (94% of the participants were white and 6% were \u201cother\u201d. A majority (60%) of the families were Jewish<\/span><span style=\"font-weight:400\"> and about 35% were Christian.)\u00a0\u00a0<\/span><\/em><\/p><\/blockquote>\n<p><span style=\"font-weight:400\">The participants were given the same silhouettes in a questionnaire as in the previous research (fig. 1). Additional data regarding weight and eating were also collected using the questionnaire. For example, frequency of <\/span><i><span style=\"font-weight:400\">concerns about weight, feeling guilty about eating, holding back at meals <\/span><\/i><span style=\"font-weight:400\">and <\/span><i><span style=\"font-weight:400\">dieting<\/span><\/i><span style=\"font-weight:400\"> were measured by asking participants to select one of the following options: <\/span><\/p>\n<ol>\n<li><span style=\"font-weight:400\">never<\/span><\/li>\n<li><span style=\"font-weight:400\">rarely<\/span><\/li>\n<li><span style=\"font-weight:400\">sometimes<\/span><\/li>\n<li><span style=\"font-weight:400\">often<\/span><\/li>\n<li><span style=\"font-weight:400\">almost always. <\/span><\/li>\n<\/ol>\n<p><span style=\"font-weight:400\">The results from the sons and daughters were very similar to the previous research study (1985) &#8211; in general, women were more dissatisfied than men with their body image. The sons showed almost no difference, on average, between their ideal and their current weight. Fathers, mothers and daughters all showed a notable disparity between their current figure and their ideal figure. <\/span><\/p>\n<p><span style=\"font-weight:400\">The researchers then analysed the responses to how these groups thought about this disapirty between their current figure and their ideal. The results of the questionaires showed that mothers and daugthers often reported concern about their weight, whereas most fathers and sons did not. Fathers also did not \u201chold back\u201d during meals and dieted less. Furthermore, fathers seemed to recognize that they were overweight but did not seem to change their attitudes or behaviours because of this. The researchers concluded that although fathers were dissatisfied with their current body shape, this did not lead to discomfort or concern, whereas it did in the female participants (i.e. mothers and daughters).<\/span><\/p>\n<p><b>Additional Research \u2013 <\/b><i><span style=\"font-weight:400\">What women think women want (<\/span><\/i><span style=\"font-weight:400\">Cohn and Adler, 1992)<\/span><\/p>\n<p><span style=\"font-weight:400\">An interesting replication of this research added an additional question to the silhouette questionnaire. They asked college aged males and females to not only identify the same figures as the previous research (i.e. ideal, current, opposite gender\u2019s ideal), but they also asked to identify what they thought members of their same gender thought was the ideal. For instance, men were asked to identify what they thought other men viewed as the ideal for a male. The results of this research reflect prior studies in that the females believed the male\u2019s ideal was thinner than their current weight. Interestingly, the females selected \u201cPeer Ideals\u201d as less than what they actually believed was their ideal weight. The men on the other hand, selected Peer Ideals as being larger than what they themselves believed to be the ideal. <\/span><\/p>\n<p><b>Critical Thinking Questions <\/b><\/p>\n<p>&nbsp;<\/p>\n<ul>\n<li><b><span style=\"font-weight:400\">How can these research studies be used to support possible cognitive explanations of the development of symptoms of bulimia nervosa?
