  1. Dependent variable in all models: Number of pumps on each balloon that did not burst. Model 1 and Model 2 were fit to the remaining balloons of the long-manipulation conditions, Model 3 and Model 4 were fit to the remaining balloons of the short-manipulation conditions; Model 5 was fit to all balloons of all conditions. For a more detailed description of each model, see main text. With the treatment contrast, the reference level of a given factor was used to estimate the other levels. These were lucky, long, Bin 2 (Model 4), and Bin 3 (Model 2). Significant effects are in bold. SE: standard error; SD: standard deviation.
