12 Assume no change in your income or purchasing power of $100
Intertemporal Choice The study of the relative value people assign to two or more rewards at different time points. $99 now or $100 in a year? Assume no change in your income or purchasing power of $100

13 Intertemporal Choice The study of the relative value people assign to two or more rewards at different time points. $40 now or $100 in a year?

14 Intertemporal Choice The study of the relative value people assign to two or more rewards at different time points. $40 now or $100 in ten years?

15 Temporal Discounting – The devaluation of anticipated outcomes as a function of their anticipated delay $100 in a year worth about $40 today.

What is Addiction? DSM Criteria for substance dependence Tolerance Withdrawal Taking more than intended Unsuccessful efforts to cut down A lot of time devoted to the substance Giving up other things Continued use despite adverse consequences

31 Opponent Process Theory and Addiction
Recall… Hedonic contrast: Experiencing hedonic change when stimulus presented (“A process”), followed by opposite change (“B process”). Hedonic habituation: Over repeated exposure, reduced hedonic change to stimulus. Hedonic withdrawal: Over time, emergence of a long-lasting, high-amplitude after-reaction that is opposite to the original hedonic change.

45 Components of Willpower
Licking marshmallow is clever, but bad idea. Distraction is a better idea. Why?

46 Components of Willpower

52 Component 2: Ability DV: Persistence task
Roy Baumeister Component 2: Ability Condition Time Attempted (min) Radish Cookie Control DV: Persistence task

53 Component 2: Ability DV: Persistence task
Roy Baumeister Component 2: Ability Condition Time Attempted (min) Radish Cookie Control DV: Persistence task

54 Component 2: Ability Can the willpower muscle be strengthened?

58 Combat Temptation Recall… Hot / cold empathy gap – People in a cold state mispredict how they will behave when in a hot state. People tend to overestimate the strength of their own willpower and/or underestimate the influence of the hot state. Sexual decision-making (Ariely & Loewenstein, 2006)

59 Combat Temptation Precommitment – Secure current preferences against future expected temptation by eliminating the future temptation.

60 Combat Temptation Precommitment -- Secure current preferences against future expected temptation by eliminating the future temptation. Don’t buy television Gastric bypass Antabuse Block websites (stayfocusd.com)

61 Increase Motivation -Side contract

63 Increase Motivation Side contract (e.g., www.stickk.com)
Making resolutions in public Better goal setting Set concrete and difficult goals “Do your best” results in not doing your best. Breakup large goals into smaller sub-goals Keep track of accomplished goals

64 Improve Ability Increase mind control Strengthen willpower muscle
Meditation (even short term) Seems to improve mind control. Not entirely sure why. Strengthen willpower muscle In same or different domains of life Just keep practicing
