For 10 points, identify these phenomena, examples of which include anger and joy.
Ortony, Clore, and Collins developed a computational model of these phenomena. Rosalind Picard is a leading proponent of programming computers to recognize these phenomena. According to Solomon and Corbit's opponent-process theory, these phenomena disrupt homeostasis and are inversely proportional to their opposites. Robert Plutchik constructed a "wheel" of these entities and argued that they evolved biologically, in contrast to Carroll Izard, who thought they were hardwired into humans and identified ten major ones. Based on his studies of the Fore tribesmen, Paul Ekman argued for six universal ones. According to the Cannon-Bard model, these phenomena precede physiological reactions. They arise from the combination of arousal and cognition according to the two-factor theory developed by Singer and Schachter.
