Columns 1–3: unit of observation is a whole trial; column 4: unit of observation is a single solution. For columns 2 and 4, the dependent variable is solution distance [measured as log(1+ difference from optimal distance)], so lower numbers correspond to better performance.*P < 0.05; **P < 0.01; ***P < 0.001
