Developments of emotional and social differences are not inter-dependent. (A) Positions in the light-dark box test indicate that ParObsParPH mice did not develop the chronic stress reactions, ParObsIsoEE mice developed chronic stress reactions which were stronger than that of ParObsIso mice in the early phase, and ParObsIsoFLX developed stress reactions in the late phase (n_xScenIso = 8, n_ParObsParPH = 5, n_ParObsIsoEE = 5, n_ParObsIsoFLX = 5). (B) Nose poking times in the female stranger test indicate that ParObsParPH, but not ParObsIsoEE and ParObsIsoFLX, mice develop the social differences of ParObsIso mice (n_xScenIso = 5, n_ParObsParPH = 5, n_ParObsIsoEE = 5, n_ParObsIsoFLX = 5). *, 0.01 ≤ p < 0.05; ^**, 0.001 ≤ p < 0.01.
