Ninety nine infants were observed at entry into child care and at 3-mo
nth intervals during the first 6 months. We examined changes in relati
ons among indices of adjustment and caregiver behaviors and which entr
y variables predict patterns of 6-month adjustment. Toy play shows no
systematic relation with infant affective behavior at entry, yet 6 mon
ths later it is associated with positive affect and reduced social inv
olvement. Caregiver interaction also changes; after 6 months expressiv
e children receive more and different forms of attention than do nonex
pressive children. Bowlby's (1969) account of institutionalized infant
s was used to identify different patterns of adjustment. Despair-like
infants were distressed, immobilized, and self-soothing at entry. Infa
nts who were detachment-like (i.e., object centered, happy, and social
ly unengaged after 6 months) received less attention from caregivers a
t entry. Some 6-month patterns have their roots in temperament disposi
tions, with differential outcomes determined largely by caregiver resp
onsiveness.
