The Early Intervention Research Institute (EIRI) reviewed extensive data reported by early intervention projects. Among surprising findings were that half-day programs produced as many gains as full-day programs, and programs which expected parent involvement were not more effective than those which did not. Current EIRI research efforts are…

The Mutual Regulatory Model is used to describe the infants' dual task of regulating simultaneously his internal emotional state and his engagement with the external environment. (Author/BB)

Describes a study done to determine whether the degree of children's familiarity with component words was related to (1) their ability to produce productive patterns as opposed to associative and grouping patterns, and (2) their ability to use broader scope rather than lexically based patterns. (SED)

Describes two experiments that examined whether the amplitude of the human eyeblink by a mild tap between the eyebrows can be increased if a brief tone is presented simultaneously with the tap and how these effects change from newborn infants to adults. (HOD)

Compares a group of well-educated mothers who preferred to be home caring for their infants with a group who preferred to be employed to determine how employment preference affects the development of maternal separation anxiety. (HOD)

Observation indicates that affect is experienced prior to organized thought. After five months emotional responses are increasingly differentiated and independent of physical state. All childhood learning is propelled by affect. Adults who work with children must recognize their emotions to facilitate their acquisition of skills and knowledge.…

Current research concerning affective development in infants and children is selectively reviewed. The focus of findings and discussion is on three general and related topics: (1) expression of emotion and affective interaction in infancy; (2) socialization and regulation of emotion; (3) comprehension of emotions and empathy with others by…

Compares the separation distress of 26 19-month-old Downs Syndrome infants in the Strange Situation with that of 43 normal infants who were observed at 12 1/2 and 19 1/2 months to assess whether Downs Syndrome infants responded more similarly to cognitively comparable normals than to age-comparable normals. (HOD)

Reviews and critiques research that has assessed the effect of infant temperament on caregiver behaviors and concludes that the relationship between temperament and caregiving behavior has not been adequately tested. Offers conceptual and methodological guidelines for future research. (HOD)

Tests the validity and reliability of a scale (Mental Development Scales: Birth to Three Years) designed to assess developmental levels of children from birth to three years. (HOD)

Based on data collected prenatally and during infants' first 2 years of life, this study attempted to discriminate among three major attachment classifications and to account for qualitative changes in attachment relationships. Data included maternal and infant characteristics, mother-infant interactions, life-stress events, and family living…

Examines possible correlates of difficult temperament by testing 152 adopted and 120 nonadopted infants at 12 and 24 months. Finds no significant relationships between parental reports of difficult temperament and other aspects of infant development, the home environment, or parental personality. Questions the utility of the construct of difficult…

In the four studies reported, facial expressions of emotion are considered to be not merely responses indicative of internal states; they are also stimulus patterns that regulate the behavior of others. Results indicated that one-year-old infants seek out and use maternal facial expressions to monitor behavior. (Author/DST)

Examined home-reared and institutionalized infants in Greece to find sex differences in social-vocal behaviors as assessed by Differential Vocal Responsiveness (DVR) to mother/caretaker versus stranger interactions. Results suggest that early differences in vocal-interactional patterns, and possibly cognitive processing, may be attributable to…

Determines whether early hemispheric differences exist in tactual processing by testing infants and preschoolers on six cross-modal tasks. Results are the first to demonstrate a left-hand superiority for information processing in children as young as two years. (Author/AS)
