Toddlers may bite as a reaction to being forced to be part of a group. Toddlers communicate in a physical manner but do not always connect the social consequences with their actions. By analyzing the circumstances surrounding a biting incident, teachers can redirect the child's energy and avoid a situation where biting might occur. (PAM)

Observers used two Q-sorts to describe mothers' and infants' behavior at home. Mothers of more difficult children were less sensitive than other mothers. There was a strong relation between maternal sensitivity and infant attachment. Mothers of more secure infants noticed and enjoyed their babies more than mothers of less secure infants. (BC)

Parents completed the Infant Characteristics Questionnaire (ICQ), and their depression and anxiety were measured, during pregnancy and the postpartum period. The ICQ scores formed two components in the mothers' analysis, and one in the fathers'analysis. Predictors of postpartum ICQ scores were the postpartum ICQ components and the anxiety and…

This study evaluated the effects of completing infant development questionnaires on mothers whose ability to provide an appropriate caregiving environment for their infants was suspect. The 18 mothers who completed the questionnaire were found to be more accurate observers of their infants than 18 control mothers who had not completed the…

Describes infant and toddler biting behavior as related to developmental differences in exploring the environment, learning cause-effect relationships, and using power to elicit a response. Discusses ways to deal with biting at each level, how to support parents dealing with the behavior at home, and the importance of taking biting related to…

Three longitudinal studies examined means-ends behavior of 6- to 8-month olds. Found that intentional means-end behavior increased between 6 and 7 months, with 7-month olds' performance influenced by the presence of a toy on the cloth. Performance was the same when cloth was attached to or separate from the toy. By 8 months, infants adjusted…

Compared everyday infant experiences among central Africa's Aka hunter-gatherers and Ngandu farmers. Found that Aka were more likely to be held, fed, and asleep or drowsy. Ngandu were more likely to be alone and to fuss or cry, smile, vocalize, or play. Crying, soothing, feeding, and sleeping declined over time for both; distal social interaction…

Evaluated respiratory sinus arrhythmia (RSA) and heart period in 5-month-olds during interaction challenges. Found that during object-mediated challenge, RSA increases were uniquely related to positive engagement. During person-mediated challenge, subjects showed more complex integration of autonomic and behavioral responses such that only infants…

Two experiments examined development of the ordinality concept in infants. Found that 11-month-olds successfully discriminated, whereas 9-month-olds failed to discriminate sequences that descended in numerical value from sequences increasing in numerical value. Nine-month-olds could discriminate the ordinal direction of sequences that varied in…

Assessed development of infants' sensitivity to two nested amodal temporal relations in audible and visible events. Found that sensitivity to synchrony was present by 4 weeks, remaining stable across age. Sensitivity to composition emerged by 7 weeks, increasing dramatically with age. Noted pattern of increasing specificity in perception…

A longitudinal study examined memory span at 5, 7, and 12 months in full-term and low-birth-weight preterm infants. Findings were similar for both groups: longer spans were more difficult, especially at younger ages, memory capacity increased over first year of life, there was marked recency effect for spans of 3 and 4 at all ages, and modest…

From Aesop to Sun Tzu, the importance of working together has long been acknowledged. Yet as long as cooperation has existed, so have the difficulties associated with it. Pooling two fields might mean twice the power, but this union also brings twice the jargon, twice the competing theories, and twice the head butting. Nonetheless, in this…

Attachment theorists assume that maternal mental representations influence responsivity, which influences infant attachment security. However, primary studies do not support this mediation model. The authors tested mediation using 2 mother-infant samples and found no evidence of mediation. Therefore, the authors explored sensitivity as a…

This study was designed to provide a general picture of infant vocal-motor coordination and test predictions generated by Iverson and Thelen's (1999) model of the development of the gesture-speech system. Forty-seven 6- to 9-month-old infants were videotaped with a primary caregiver during rattle and toy play. Results indicated an age-related…

Reddy and Trevarthen explore what we can learn from emotionally engaging with babies. Theirs is a different approach from 20th-century psychology, in which doubt and detachment play a role in discerning other people's feelings and thoughts. Instead, the authors suggest that emotions are the key to psychological engagement. When interacting with an…
