| Question | Answer |
| Concurrent reinforcement schedules | two or more schedules simultaneously availble on independent reinforcement schedules (responding on ones does not effect the other) |
| Examples of self-control | Studying, sticking to a diet/exersize plan, giving up smoking, finishing planned projects, Saving money |
| What do self-control situations have in common? | A choice between a smaller but more immediate reinforcer, and a larger but delayed reinforcer |
| Impulsive choice | Choosing the smaller more immediate reinforcer |
| Self controlled choice | Choising the larger more delayed reinforcer |
| Why do we experience self-control experiences? | Because one alternative is more valuable based on amount, the other is more valuable based on delay |
| Experimental analogue of self-control | A left key and a right key presented simultaneously. Left key has a reinforcement delay of 3 seconds then availability of 1 second of food. The right key has a delay of 10 seconds then availability of 3 seconds of food. |
| Experimental analogue for humans? | The money over delay thing |
| How do we investigate the effect of delay experimentally? "How much value does a reinforcer lose if it is delayed by a given amount? | Titrating amount procedures. Present two options which are different and then make the one not chosen more valuable in each trial until the subject choses it. |
| The point in which a subject changes their preference in a titrating amount procedure? | The subject's indifference point. |
| Hyperbolic discounting equation | Value = Amount/1+kDelay k equals the constant. The higher the k the quicker the reinforcer loses value, more likely to select smaller sooner. Low k, reinforcer loses value slower, more likely to choose larger later |
| Amount effect in humans | Larger amounts, $100 < $10,000,000, have smaller k, therefore, lose value slower (are discounted more slowely) |
