Maternal Sensitivity and the Learning-Promoting Effects of Depressed and Non-Depressed Mothers' Infant-Directed Speech.

The hypothesis that aspects of current mother-infant interactions predict an infant's response to maternal infant-directed speech (IDS) was tested. Relative to infants of non-depressed mothers, those of depressed mothers acquired weaker voice-face associations in response to their own mothers' IDS in a conditioned-attention paradigm, although this was partially attributable to demographic differences between the two groups. The extent of fundamental frequency modulation (DeltaF(0)) in maternal IDS was smaller for infants of depressed than non-depressed mothers, but did not predict infant learning.

Maternal secure base support and preschoolers' secure base behavior in natural environments.

Bowlby and Ainsworth's theory of attachment poses that concurrent caregiving behavior is a key factor in influencing and maintaining a child's organization of secure-base behavior, and ultimately, security throughout childhood. Empirical demonstrations of the relation between the constructs after infancy are relatively scant and research is needed to examine the relation between the variables across a wide range of contexts, over longer observational periods, and in developmentally appropriate ways. Two studies of preschoolers and their mothers were conducted in naturalistic settings.

Maternal preconceptions about parenting predict child temperament, maternal sensitivity, and children's empathy.

This study examined the influence of maternal preconceptions on child difficult temperament at 6 months and maternal sensitivity at 12-15 months and whether all 3 variables predicted children's empathy at 21-24 months. Within a low-income, ethnically diverse sample of 175 mother-child dyads, path models were tested with 3 empathy indices (prosocial, indifference, inquisitive) as outcomes. Results indicated that maternal preconceptions significantly predicted child difficult temperament, maternal sensitivity, and children's empathy.
