The original preregistration files and links to the time-stamped preregistration for each experiment are provided below. [Experiments 1 and 2][1] [Experiment 3][2] [Experiment 4][3] [Experiment 4 - Retest][4] [Experiments 5 and 6, & Retest][5] [Experiment 7][6] Notes on the preregistrations: 1. Experiments 1 and 2 were conducted simultaneously, by assigning participants to one of the two conditions in a counterbalanced order. For the sake of consistency with other experiments reported in the paper, we referred to them as two separate experiments. Furthermore, Experiment 1 (impulsive choice) in the preregistration is presented as Experiment 2 (fast choice) in the paper, and Experiment 2 (deliberative choice) in the preregistration is presented as Experiment 1 (slow choice) in the paper. 2. The preregistration for Experiments 1 and 2 contained some inconsistency. In the introduction of the preregistration, we discussed previous work showing that the training effect is more pronounced for stimuli that are perceived to be more appetitive (in line with the Behavior Stimulus Interaction theory discussed in the paper). In the Hypotheses section, we accordingly predicted an effect on choices for the high value pairs in slow choice condition (i.e., Experiment 1 in the paper), but not for the low value pairs. For the fast choice condition (i.e., Experiment 2 in the paper), we did not have directional hypotheses. However, regarding the effect of training on stimulus value, we predicted a difference between go and no-go items for both Experiment 1 and 2, but failed to mention that this effect was predicted only for items with high initial value. Furthermore, in the Analysis Plan part we did not mention these predictions, and instead described data analyses in an exploratory manner. In the paper, we will present directional hypotheses in line with the ones outlined in the Hypotheses part (plus that the effect on the auction task was only expected for high-value stimuli), to stay close to the Behavior Stimulus Interaction theory that we subscribed to while conducting the first two experiments. Note that these predictions are actually not in line with the results we observed. 3. The preregistration of Experiment 1 and 2 failed to mention that in the choice task with time limit, when participants failed to choose within 1.5 seconds, the food items would be replaced by a prompt saying "Choose Faster!" for 500ms. Note that this prompt was actually used when conducting the experiments. The method part in the paper now correctly mentions the use of this prompt when time limit was implemented in the choice task.
