Emotions are viewed as having evolved through their adaptive value in dealing with fundamental life-tasks. Each emotion has unique features: signal, physiology, and antecedent events. Each emotion also has characteristics in common with other emotions: rapid onset, short duration, unbidden occurrence, automatic appraisal, and coherence among responses. These shared and unique characteristics are the product of our evolution, and distinguish emotions from other affective phenomena.

We explore the implications of a hierarchical structure, consisting of (a) the higher order dimensions of nonspecific Positive Activation and Negative Activation and (b) multiple specific negative affects (e.g., fear, sadness, and anger) and positive affects (e.g., joviality, self-assurance, and attentiveness) at the lower level. Emotional blends of the same valence (e.g., simultaneously experiencing both fear and sadness) are an essential part of this structure and form the basis of the higher order Negative and Positive Activation dimensions. Mixed cross-valence emotions (...) (e.g., feeling both nervous and alert) are not central to this hierarchical scheme but are compatible with it. We examine the frequency of pure emotional states, same-valence emotional blends, and cross-valence mixed emotions in a large momentary mood sample. (shrink)

After using descriptive experience sampling to study randomly selected moments of inner experience, we make observations about feelings, including blended and multiple feelings. We observe that inner experience usually does not contain feelings. Sometimes, however, feelings are directly present. When feelings are present, most commonly they are unitary. Sometimes people experience separate emotions as a single experience, which we call a blended feeling. Occasionally people have multiple distinct feelings present simultaneously. These distinct multiple feelings can be of opposite valence, with (...) one pleasant and the other unpleasant. We provide examples that inform theories of emotions and discuss the important role observational methodology plays in the effort to understand inner experience including feelings. (shrink)
