Full context:   Lisa Feldman Barrett argues that affect is most likely innate in mammals (and possibly all vertebrates), whereas emotions are constructed mental representations that emerge from the brain's interpretation of interoceptive prediction signals combined with past experience (organized as concepts) and signals from the outside world. In philosophical psychology, particularly in the work of Carl Jung, feeling is considered one of the four primary functions of consciousness, alongside thinking, sensation, and intuition. Unlike emotions, which are often reactive, Jung defined feeling as a rational function that evaluates and assigns value.
