Brief Summary

The effect of emotional induction of sadness (vs. joy) on the mental representation of the body image through the virtual reality

Detailed Description

The general objective of this study is to analyze the impact of emotional induction (sadness vs. joy) on the two dimensions (perceptive and affective) of body image with the help of virtual reality. Thus, it is hypothesized that a negative emotional induction may partially explain the change in body image measures.

Conditions

Study Groups

Sadness condition

Group Type: EXPERIMENTAL

Sadness induction

Intervention Type: OTHER

Sadness state will be induced with a Virtual Reality program. Mood induction will be done with an emotional induction procedure in virtual reality (Mood induction parks (Baños et al., 2006)). This technique has proven to be effective in previous studies (e.g., van Strien et al. 2013). Virtual reality software simulates an urban park and includes several methods of sadness induction: Velten's tasks (1968) (sentence formulations with negative content about the self; for example, "I am not valuable", "I see no future"); visualization of a image bank with emotional content from the international system of emotional images (IAPS, Lang et al.,1999); listening to a piece of music and viewing a film scene that demonstrated his effectiveness in inducing positive affect (Donen et al. 1952; Eich and Metcalfe 1989; Gross and Levenson 1995), and an autobiographical memory test.

Happiness induction

Intervention Type: OTHER

Happiness state will be induced with a Virtual Reality program. Mood induction will be done with an emotional induction procedure in virtual reality (Mood induction parks (Baños et al., 2006)). This technique has proven to be effective in previous studies (e.g., van Strien et al. 2013).
