Document Summary
Aroused subjects all reported stronger emotion, but type reported varied with stimuli. So, from its inception, emotional expression is shaped by social interaction. Via perceptual input via thalamus to cortex & activation of the ans (for somatic responses) That is, influence moves both bottom up (visceral to cognitive) and top-down (cognitive to visceral) I. e. our subjective feelings are an interpretation we make of our body"s reaction to stimuli vs. low-power postures (limbs crossed, hold face, etc) Alters hormonal balance (power => raise testosterone, lower cortisol) Including array of structures of limbic system, and the thalamus, the hypothalamus, and the frontal cortex. Here, we will focus on role of amygdala (part of limbic system) and frontal cortex upper eyelids, tighten lower eyelids, stretch lips horizontally) w/o mentioning an emotion. When asked, subjects reported feeling appropriate emotion (e. g. above expression => fear) Expressions also produced changes in heart-rate, skin temp, etc. (e. g. fear: heart up, temp down)
