Parents' raw (%) and standardized scores, (mean, SD).

CFMT: Parents N = 33; Mothers N = 19′; Fathers N = 14.Face/shoe matching: Parents N = 32; Mothers N = 18; Fathers N = 14.Scores significantly below zero, **ppScore significantly above zero, ∼p = 0.01.The CFMT raw scores for the controls are taken from Bowles et al [42] (Table 2, raw total scores for early middle age (36–49 years), N = 21). Caution is necessary when interpreting statistical comparisons with raw data because scores are not age adjusted, however one-sample t-tests suggest that both the mothers, t (18) = 2.06, p = 0.05, and fathers, t (13) = 2.69, p = 0.02, scored significantly below average.
