At which age do most infants begin to fear strangers?
a. 2 months
b. 4 months
c. 6 months
d. 12 months
ANS: C
Between ages 6 and 8 months, fear of strangers and stranger anxiety become prominent and are related to infants' ability to discriminate between familiar and unfamiliar people. At 2 months, infants are just beginning to respond differentially to their mothers. The infant at age 4 months is beginning the process of separation-individuation, which involves recognizing the self and mother as separate beings. Twelve months is too late; the infant requires referral for evaluation if he or she does not fear strangers by this age.
