Attribution enables the individual to explain his own behaviours and those of others, to interpret what is happening around him and to search for plausible causes that determine an event or action. Attribution Theory must explain the occurrence of certain cognitions using inference, thus reaching a conclusion on the basis of evidence and reasoning, using behaviour as a starting point.
William James, known as the father of American Psychology, developed along with his 19th Century fellow psychologist Carl Lange the James-Lange theory which considers that environmental events lead to the apparition of muscular and visceral responses, and that these responses eventually determine emotions. Instead of feeling an emotion and subsequent physiological (bodily) response, the theory proposes that the physiological change is primary, and emotion is after that experienced, as the brain reacts to the information received via the body’s nervous system.
The emotion follows the behaviour, and does not determine it.
