A longitudinal study addressed the question of stability of individual expressive behaviors and replicated the basic findings of a cross-sectional study. Subjects were 25 infants for whom videotape records were available of four diptheria-pertussis-tetanus (DPT) inocculations scheduled at roughly 2, 4, 6, and 18 months. (Author/RH)

Research on perceptual and cognitive capacities of the newborn has revealed that state variables typically interfere with or override the neonate's attentional and stimulus processing tendencies. This finding argues for the power of early state variables as behavioral determinants and, further, that neonatal state measures might provide good…

Tested the hypothesis that development of secure attachments is predictable from synchronous, and insecure attachments from asynchronous interactions across the first year. Findings from 30 dyads (10 secure, 10 avoidant, 10 resistant) supported the hypothesis at one and three months, with synchronous interaction observed at significantly,…

Early temperament was assessed at ages six, 13, and 24 months via mother ratings on age-appropriate versions of the Infant Characteristics Questionnaire (ICQ). Home observations of mother-toddler interactions at age 24 months were made, and behavior sequence variables were analyzed. The 24-month form of the ICQ was developed in this study.…

Data from four studies answer Carey's (1982, 1983) critical questions about the validity of the original Infant Temperament Questionnaire (ITQ). Discussion illuminates the complexity of establishing the construct validity of psychological assessments used with infants. Data suggest that both the original and revised Carey ITQs fail discriminant…

Scores generated by two optimality and three complication scales used to assess perinatal risk for 103 infants were compared for accuracy in predicting a variety of neonatal and infant outcome measures. Results suggested an advantage in favor of the three complication scales. (Author/RH)

Explores whether transactional/interactional, environmental, or developmental status models best represent growth from infancy to early childhood. Attempts to identify features of the social environment important for specific developmental outcomes. Observations of interactions between 40 mothers and their three-month-old infants were used to…

This study used longitudinal productivity criteria to establish the phonetic skill of 20 children (followed from 9 to 16 months). The number of specific consonants produced consistently across the months predicted referential lexical use at 16 months. Prior use of at least two supraglottal consonants characterized the children achieving…

The MacArthur Communicative Development Inventory (a parent-report measure of vocabulary and syntax) was administered to 103 children (mean age 103 months) who participated in a study of temporal resolution as infants. Children who had performed above the median on the temporal resolution task demonstrated better later language development than…

A study identified the antecedent characteristics of child and family best predicting behavioral/emotional problems at three years of age. Considered were the relationship of the index of attachment security to several mother-child relationship measures and to other child characteristics, such as difficult temperament and sociability. (Author/NH)

Distress in response to brief maternal separations was examined in a sample of 93 predominantly home-reared infants using the Ainsworth strange situation paradigm. At 18 months, the age when separation protests begin to decline, securely attached infants are better able than anxiously attached infants to tolerate maternal separations. (Author/RH)

This study, with 53 Mexican-American infants, found that five predictors accounted for approximately 35 percent of the variance in receptive language at 12 and 22 months with average parental generation from Mexico (acculturation) and infant visual recognition memory accounting for 14 and 15 percent of the variance, respectively. No predictors…

Addresses the utility of a noninvasive measure of cardiac vagal tone in predicting developmental outcome among infants at risk for cognitive disabilities. Results suggest that measurement of cardiac vagal tone may provide an important means for assessing risk in birth-stressed populations. (Author/RH)

Comparison of 72 middle and 72 low socioeconomic status (SES) families of infants with developmental disabilities, on measures of maternal stress and infant development, found that regression analyses predicted 81% of the variance in later developmental level from initial Bayley Mental Age, initial Mental Development Index, SES, initial maternal…

Assessed the relation between behavior problem ratings and family relationship quality among 29 mothers and their 4-year-old children. Findings suggest that the absence of positive parental behaviors is as important as the presence of negative behaviors in behavior problem development. (RH)
