Upon Further Reflection. Chapter 7: Cognitive Science and Behaviorism. Quote 14

“Kahneman and Tversky have reported that people say they would be less likely to buy a second ticket to the theater if a first had been lost than to buy a ticket after losing the money they had set aside for that purpose. The difference, they say, is due to a difference in categorization. But a difference in relevant contingencies of reinforcement should not be overlooked.” (pp. 104-105)
