Procesos cognitivos y emocionales en trastornos de la conducta alimentaria. Percepción de la Imagen Corporal y Toma de Decisiones en Mujeres Onubenses (PICTODEMO)

Abstract

Cognitive processes such as perceptual construction, to the powers or valences assigned to the extrinsic and intrinsic setting and decision-making, they are of research interest because of the implications they pose to people in their adaptability to the environment, with more or less success. Therefore, this study attempts to explore whether there are differences in factors involved in these processes, among a group of teenage girls with eating disorders (n = 23) and a control group (n = 51) of the same age stratum (15 years) similar socioeconomic level. The results have shown, through the IGT, significant differences between both groups in the evolution of learning the task of decision-making, with clinics who presented a more disadvantaged performance in the last forty trials (b4: F = 8,949, p = .004; b5: F = 4.109, p = 046), they also showed higher levels of perceptual distortion of body image overestimation (x2 = 12.917, p = .001), and these levels of distortion, correlated inversely with the total Gambling Index (Tb = -, 195, p =, 048 ). The control group showed anthropometric indices, body circumferences and general nutritional variables (IN: t = 3.214, p = .002, EN: x2 = 11.810, p = .008) significantly higher than the TCA group, and variables of fat composition correlated with the parameter of the cognitive model PVL: alpha (AGB: r = -, 364, p = .005), consistency (IAM: r = 461, p = .000), and lambda is related with Nutritional Index (r =, 251, p =, 031) directly. These results of the analyzed factors of cognitive and emotional processes, involved in the TCA, suit Somatic Marker Theory, Damasio (1996a).
