UncertainTime: on the intertemporal uncertainty questions, was the later (l) option uncertain, the now (n) option, or both (b)? 

UncertainType: u = uncertainty (uncertain outcomes), v = variability (uncertain amounts)

UncertaintyFirst: order of presentation of scenarios. 1 = intertemporal choice with uncertainty was first, 0 = intertemporal choice under certainty was first
