1) Have any data been collected for this study already? No, no data have been collected for this study yet.
2) What's the main question being asked or hypothesis being tested in this study? We determine in chained choice-based matching tasks in the domain of losses, whether participants (1) consistently exhibit delay aversion (negative implied interest rates) or consistently exhibit delay tolerance (positive implied interest rates), and (2) whether they exhibit subadditivity, additivity, or superadditivity in intervals. We predict that superadditivity of intervals will occur at a higher rate among the delay averse, whereas subadditivity will occur at a higher rate among the delay tolerant.
3) Describe the key dependent variable(s) specifying how they will be measured. Indifference points between single-dated payment over three adjacent one-year intervals, and a single undivided three-year interval.
4) How many and which conditions will participants be assigned to?
5) Specify exactly which analyses you will conduct to examine the main question/hypothesis. We compare the indifference-inducing later payment between the subdivided and the undivided interval, which may be done using ratio- or ordinal-level information. Delay tolerance/delay aversion is that the later payment is larger/smaller than the sooner one. Superadditivity/subadditivity is that the indifference-inducing later payment is larger/smaller over the undivided interval than over the subdivided one.
6) Describe exactly how outliers will be defined and handled, and your precise rule(s) for excluding observations. We will drop participants that violate monotonicity on one or more matching tasks. For instance, when a participant chooses a) over b), but then chooses d) over c)
a) pay 200 today vs b) pay 160 in a year
c) pay 200 today vs d) pay 250 in a year
We also drop participants that make multiple switches on one or more matching tasks.
7) How many observations will be collected or what will determine sample size? No need to justify decision, but be precise about exactly how the number will be determined. 1000
8) Anything else you would like to pre-register? (e.g., secondary analyses, variables collected for exploratory purposes, unusual analyses planned?) Nothing else to pre-register.
