6. Are You Happy? Flashcards
What are the 2 types of utility that is supposed to determine happiness?
Experience utility and decision utility
What is expected utility theory?
rules of rationality that should govern decision utility. Doesn’t say anything about hedonistic experiences.
What are the 2 versions of ourselves?
The experiencing self
The remembering self
How does the experiencing self measure pain?
Measures pain or pleasure on the spot.
“Does it hurt now?”
How does the remembering self measure pain?
summarises the overall experience
“How was it, on the whole?”
How do we measure pain/pleasure?
Hedonometer
measure pain and pleasure at the moment. Varies as a function of time. Duration weighted, computation is “area under the curve” so it assigns equal weights to all moments.
What are the 2 factors affecting the experience of pain and pleasure?
1) Duration neglect
2) Peak-end rule
What is duration neglect?
the duration of the procedure had no effect whatsoever on the ratings of total pain
Describe the peak-end rule.
the retrospective rating of the event was well predicted by the average between the peak level of pain and at its end of the experiment.
What is the dilemma for medical practitioners?
reduce the amount of pain felt (experiencing) vs memory of pain (remembering)
If objective is to reduce memory of pain, what should the medical practitioner do?
1) Lower peak intensity of pain
2) Gradual relief may also be preferable to abrupt relief. Patients retain a better memory when pain at the end of the procedure is relatively mild.
If objective is to reduce overall pain felt, what should the medical practitioner do?
conduct the procedure swiftly
Describe the coldhand situation.
Participants asked to put their hand in painfully cold water until asked to remove it, and given warm towel. Short episode - 60s at 14degrees.
Long episode - 60s at 14degrees + 30s at 13degrees
(warm water flow into the tub for last 30s, just enough for them to detect a slight drop in pain intensity)
Participants experienced the short and the long episodes, each with a different hand. Participants were given a choice about the third trial. They were told that one of their experience they had with their left hand or right hand.
What was the coldhand experiment designed to do?
The experiment was designed to create a conflict between the interests of the experiencing and the remembering selves, and also between experienced utility and decision utility.
In the coldhand experiment, what was the experiencing and remembering self’s respective verdict of the pain?
Experiencing self – long trial was obviously worse.
Remembering self – peak-end rule predicts a worse memory for the short than long trial. Duration neglect predicts that the difference between 90s and 60s of pain would be ignored. Hence participants would have a more favorable memory of the long trial and choose to repeat it.
