Early Trials: Activity for learning with behavior equated.

All Trials: Activity for Learning. (Top) Significantly active areas for children from either LSES or HSES families for novel rule > familiar rule contrast (one sample t-test). (Bottom) Significantly active areas for the two sample t-test comparing children from LSES families to children from HSES families for the novel rule > familiar rule contrast. Only areas that were above baseline for one group compared to the other are reported (e.g., no area that was below baseline for children from HSES families, but at baseline for LSES families was reported).
