Table 2.

Contingency table between impulsiveness groups and the adaptation of the PBI across blocks as indexed by the model estimates. A positive estimate indicates a global increase in the PBI across blocks, used as an index of adaptation capacities. A negative estimate indicates an absence of evolution or even a decrease in the PBI across blocks and thus, no adaptation to task demands. LI: low impulsiveness, HI: high impulsiveness.
