  1. M-security = attachment security with mother; F-security = attachment security with father
  2. #p < .1; *p < .05; **p < .01 (two-tailed)
  3. aChild sex is coded: -1 = girl; 1 = boy
  4. bAge in months
  5. cN = 127 (due to the fact, that the SES questionnaires from 33 participants did not returned, and thus there was some missing data)
