Disentangling three valence-related dimensions of emotion valuation: The good, the pleasant, and the desirable.

People place value on emotion categories that inform which emotions to cultivate and which to regulate in life. Here, we examined how people's beliefs about emotion categories varied along three valence-related dimensions: evaluation (good, bad), hedonic feeling (pleasure, displeasure), and desirability (want to feel, do not want to feel). In Studies 1A and 1B, we found that evaluative (good/bad) and hedonic (pleasant/unpleasant) ratings were distinct for certain emotions including lust, anger, shame, fear, and guilt.

Fear-related psychophysiological patterns are situation and individual dependent: A Bayesian model comparison approach.

Is there a universal mapping of physiology to emotion, or do these mappings vary substantially by person or situation? Psychologists, philosophers, and neuroscientists have debated this question for decades. Most previous studies have focused on differentiating emotions on the basis of accompanying autonomic responses using analytical approaches that often assume within-category homogeneity. In the present study, we took an alternative approach to this question.

Cortical and subcortical mapping of the allostatic-interoceptive system in the human brain: replication and extension with 7 Tesla fMRI.

The brain continuously anticipates the energetic needs of the body and prepares to meet those needs before they arise, a process called allostasis. In support of allostasis, the brain continually models the internal state of the body, a process called interoception. Using published tract-tracing studies in non-human animals as a guide, we previously identified a large-scale system supporting allostasis and interoception in the human brain with functional magnetic resonance imaging (fMRI) at 3 Tesla.
