A scheme for classifying attachment patterns is proposed that retains important elements of Ainsworth's system, but extends it to allow for the inclusion of more deviant patterns of behavior. The proposed scheme asserts that attachment relationships can be ordered on a continuum of felt security based upon an organizational interpretation of the…

Investigates language-normal one-year-olds' (N=14) and language-impaired two- and three-year-olds' (N=10) acquisition of words referring to three types of action. Findings revealed that, although both groups produced few of the words, the language-normal subjects comprehended the different types of action, whereas the impaired subjects did not.…

The locomotor skills of walking and running were compared in newly running infants at 5.5, 7.5, and 9.5 months of independent walking, and then again at 3 years of age. Collective variables showed transitional forms over the first few months of running, indicating a relatively continuous change across the two gait forms. (MDM)

Two experiments examined toddlers' ability to use cues to infer meaning of novel action words. Toddlers were taught labels for similar or dissimilar pairs of videotaped actions, with behavioral cues or eye gaze related to agents' intentions distinguishing similar events. Results showed that in year 2, children begin to consider…

Three studies examined 2-year-olds' ability to learn novel words when overhearing these words used by others. Found that children ages 2.5 years were equally good at learning novel object labels and action verbs when they were overhearers as when they were directly addressed. For younger 2-year-olds, this was true for object labels, but results…

Purpose: This study evaluated whether developmental reading disability could be predicted in children at the age of 30 months, according to 3 measures of speech production: speaking rate, articulation rate, and the proportion of speaking time allocated to pausing. Method: Speech samples of 18 children at high risk and 10 children at low risk for…

The study examined the effects of conducting observations as part of a broader assessment of families participating in behavior family intervention (BFI). It was designed to investigate whether the observations improve intervention outcomes. Families were randomly assigned to different levels of BFI or a waitlist control condition and subsequently…

The quality of care in infant and toddler classrooms was compared across inclusive (n=64) and noninclusive classrooms (n=400). Quality was measured using the Infant/Toddler Environment Rating Scale-Revised (ITERS-R). An exploratory and confirmatory factor analysis revealed four distinct dimensions of quality within the ITERS-R. Inclusive…

In order to examine the development of social pretend skills in the toddler period, social pretend play was observed in same and mixed age dyads. More complex social pretend play was expected in the mixed age than in the same age condition. A second purpose of the study was to compare 5-year-old children's attempts to communicate pretend meanings…

Compares Down's Syndrome children with normal siblings on various temperament dimensions, using data collected from mothers' completion of the Toddler Temperament Scale and followup questionnaire. (NH)

This study examined the effects of nutritional supplements on the duration and level of spontaneous play of 55 mildly to moderately malnourished toddlers living within the tea plantations of West Java, Indonesia. Infants were randomly assigned by their day care centers to one of three supplement groups: (1) energy and micronutrient supplements;…

This study compared the degree to which young children were placated during a standard medical evaluation by the presence of their mother, blanket, mother plus blanket, or no supportive agent. Participating were 64 three-year-olds who underwent 4 routine medical procedures. Children were rated by their mothers as attached or nonattached to…

Examined event-based memory in three groups of children between ages 14 and 25 months. Found that search task success was general in oldest group while performance was similar on a task in which success "may" have been due to recalling an object-removal event and one in which success could "only" have been due to recall of…

Developed direct observational measure of children's attachment to inanimate objects such as blankets and soft toys among object-attached and non-object-attached 15- to 31-month-olds. Procedure varied arousal levels across situations. Found support for validity of the procedure in, among other factors, its ability to capture the preference of…

Examined the degree of specificity encoded in early lexical representations by presenting 18- to 23-month-olds with object labels either correctly or incorrectly pronounced and analyzing children's eye movement. Found that children recognized the spoken words in both conditions but recognition was poorer when words were mispronounced, with effects…
