Mean log indifference delay (ID; ±95% confidence intervals) as a function of bundle size in all participants, including n = 30 who were excluded for failing one or more quality control questions.

The left panel depicts ascending and descending order groups combined and the right panel depicts individual order groups (right panel). Gray and patterned bands represent 95% confidence intervals around model-predicted effects of bundle size, based on participants’ BS1 indifference delay values (control condition). Linear indifference delay values are scaled on the right y axis to aid in interpretation.
