(a) Mean distance traveled and time spent in perimeter versus center of a novel open‐field environment. All four genotypes traveled similar distances and demonstrated a preference for the perimeter versus the center zones. (b) Mean time spent in stimulus mouse corner versus empty cup corner. The Gtf2i ^+/+ mice did not show a corner preference, but the Gtf2i ^+/− mice and the Gtf2i ^+/dup mice spent significantly more time in the stimulus mouse corner than the empty cup corner. Asterisks indicate significance where p < .05
