Given that the advertised pay rate differed from the actual pay rate among participants, we first evaluated the relation between actual pay rate for Part 1 and total points earned during the two tasks.

We conducted this analysis across all groups and within individual groups.Next, we used a logistic regression analysis to ascertain the effects of pay (low pay, coded 0; high pay, coded 1) and the presence (coded 1) or absence of additional instructions (coded 0) on task completion (coded 1) or attrition (coded 0). More specifically, the goal of this analysis was to evaluate how pay, additional instructions, and the interaction between those variables influenced the odds of task completion. We performed this analysis in R [
