TAT and Anxiety: In the open field, there were main effects for age [F(1,35) = 9.14, p < 0.05; Figure 4A, see †] and Tat expression [F(1,35) = 5.29, p < 0.05; Figure 4A, see *], both of which increased anxiety-like behavior and reduced time spent in the center of the open field compared to young adult or Tat(−) counterparts, respectively.
