Forty newborns (M age=27 hr old) of depressed and nondepressed mothers were habituated to a cold or warm temperature tube by hand. Both groups of infants habituated the temperature of the tube, as indicated by a decrease in holding, and dishabituated, as indexed by an increase in holding when the temperature of the tube changed. However, the newborns of depressed mothers (a) required twice as long to habituate; (b) showed a sensitization effect, as indexed by an increase in holding from the second to the third trial of habituation; and (c) passively handled the objects with their hand.
