  • Scientific Method

    • If a theory can accommodate all possible results then it is not a scientific theory.
    • Although strictly speaking, disconfirming an hypothesis deduced from a theory disconfirms the theory, it rarely leads to the abandonment of the theory.
    • If the theory has to be modified over and over to accommodate new findings, the theory generally becomes less and less parsimonious.
    • This can lead to discontent with the theory and the search for a new theory.
    • If a new theory is developed that can explain the same facts in a more parsimonious way, then the new theory will eventually supersede the old theory.

    • While the James–Lange theory proposes that emotions arise from physical arousal the Cannon–Bard theory argues that physiological arousal and emotional experience occur simultaneously, yet independently (Lang, 1994).
    • According to the Cannon–Bard theory, emotional expression results from activation of the subcortical centers of the brain.
  • James–Lange Theory of Emotion

    • According to the James–Lange theory of emotion, emotions arise from physiological arousal.
