Maternal singing is considered vital to infant well-being. This study focuses on vocal emotion expressions in infant-directed singing among mothers in war conditions. It examines the questions: (a) how traumatic war events and mental health problems are associated with the content and valence of vocal emotion expressions and (b) how these emotion…

This paper reports a study which examined the relationships of various facets of sensorimotor performance to abilities measured by a developmental examination of a sample of full-term and pre-term infants nine months after expected term date. This study addressed three questions: (1) Are there differences in the sensorimotor development of term…

Activities that allow infants to investigate their own environments are suggested in this disucssion of science and its relationship to cognitive development. Emphasis is placed on the infant's own manipulation of wet and dry materials such as: bathwater, food, boxes, pockets, magazines and balls, all of which are readily available in most homes.…

Provides evidence indicating a strong connection between a high level of ambient household noise and intellectual deficits at stages of infant development. Observers rated noise level from all household sources (stereos, appliances, etc.). Delays were found in sensorimotor development with high levels of noise. (Author/JN)

A cross-sectional study of language comprehension in relation to cognitive functioning in 48 10-to 21-month-old children, four at each month of age, revealed significant correlations between comprehension and five sensorimotor subscales. (Author/PHR)

The developmental pattern of concurrent synaptogenesis in rhesus monkeys is consistent with a straightforward model of relations between brain and cognitive development. Concurrent synaptogenesis is hypothesized to lay the primary cortical foundation for a series of developmental levels in middle infancy that have been empirically documented in…

Caregiver-infant transactions with 51 premature infants were studied in naturalistic observations in the home when the infants were aged 1, 3, and 8 months. Gesell developmental schedules and a sensorimotor scale were administered at 9 months. (Author/JH)

Examined infants' ability to retrieve an object from atop a slightly larger object. Found that even 5-month-olds could retrieve objects close in size and fully contiguous with their bases when demands on reaching skill were reduced. Proposed that when they fail this task, it is because they lack the skill to reach the top object without…

THE PURPOSE OF THIS STUDY WAS TO FIND OUT WHETHER SOCIAL CLASS DIFFERENCES IN INTELLECTUAL DEVELOPMENT ARE PRESENT IF (1) CHILDREN FROM SOCIALLY DISORGANIZED SLUM FAMILIES ARE COMPARED WITH CHILDREN FROM STABLE, LOW INCOME AND MIDDLE INCOME FAMILIES, (2) THE PIAGET OBJECT SCALE, A NEW MEASURE OF COGNITIVE DEVELOPMENT BASED ON PIAGET'S SENSORIMOTOR…

This discussion centers on language development in young children particularly as it relates to Piaget's work. The author believes guidelines are lacking for describing structurally the outcome of the language acquisition process at different stages and that there should be more collaboration between linguists and psychologists in this area.

Observed 12-month olds, with their mothers and independently, acting on objects from home and objects brought by the experimenter as new exemplars of previous toys. Found that conventional actions were more frequent in joint than in independent activity. In independent activity, conventional actions were more frequent with customary than with…

Three experiments explored 5- and 7-month-olds' intermodal coordination of proprioceptive information produced by leg movements and visual movement information specifying these same motions. Results suggested that coordination of visual and proprioceptive inputs is constrained by infants' information processing of the displays and have…

Learning in infancy is based on activity, beginnings, and curiosity, the so-called ABC's. Earliest behavior consists of mass activity, the period from birth to 24 months of sensory-motor development which provides the foundation for all future learning. Adults must provide space, toys, and affectionate care to help infants proceed through…

This investigation evaluated a group of 20 8-month to 2-year-old culturally disadvantaged children who were given a 1-year structured educational program as a means of environmental intervention. The program involved language training, conceptual training, and sensory-motor training. The study is the first phase of a longitudinal study to…

The purpose of this research is to show that the logical formula for equivalence, (A=A; but is not A'), originates in the early manual actions of the young child. Having two hands that are bilaterally opposed and initially function in bilaterally symmetrical action might serve to structure the form of early sensori-motor experiences and this…
