Impatience, Anticipatory Feelings and Uncertainty: A Dynamic Experiment on Time Preferences
2011
Social Science Research Network
Preserved Fulltext
Moreover, choice reversal over time is common even if temptation plays no role. We propose and measure three distinct concepts of choice reversal over time to study time consistency. ...
We study time preferences in a real-effort experiment with a one-month horizon. We report that two thirds of choices suggest negative time preferences. ...
For instance, static choice reversal either comes with dynamic or calendar choice reversal but not with both. ...

However, with two-stimulus reversal, it is difficult to determine whether response errors are due excessive perseveration, deficient learning, or other problems with updating. ...
To address this limitation, we developed a mouse three-choice touchscreen-based visual reversal task, in which the contingencies of two stimuli were switched on reversal but a third, simultaneously presented ...

We hypothesized that if oxycodone impaired behavioral flexibility, then drug-exposed rats should learn reversals more slowly than controls. ...
Reversal learning was tested 36 h after the final drug exposure. ...
Two-way ANOVAs were used to assess if performance during the reversal session (TtC) covaried with performance during the initial learning, retention, and reminder sessions. ...

Through an experiment we compare preference-based vs. uncertainty-based explanations for choice reversal over time by eliciting choices for pre-commitment and flexibility. ...
An agent with dynamically inconsistent preferences may deviate from her plan of action as the future draws near. An exponential discounter may do exactly the same when facing an uncertain future. ...
This measurement of risk did not ultimately correlate with choice reversal, commitment, nor flexibility. ...

Reinforcement contingencies were reversed repeatedly within a session. In well-trained rats, shell inactivation reduced the number of reversals completed and selectively reduced win-stay behavior. ...
Daily sessions consisted of 200 discrete choice trials, with an intertrial interval of 15 s (50 min total). ...

The ideal strategy would be to start each sequence with a choice of S1 (the first correct stimulus) until it was no longer correct, and then to switch to S2 (the second correct stimulus), thus utilizing ...
