Reflecting on obsessional play objects of infants, Hodgkin suggests that a proper understanding of these "transitional" or "cognitive" objects could lead to an educational model of a "learner" involving a number of human competencies, all developing synergistically. Contends that such a model may be truer to life than…

Three experiments used a visual fixation technique to examine whether toddlers interpret speech continuously. Found that 24-month-olds had delayed responses when a competing distractor picture's label overlapped phonetically with the target at onset, but not when the pictures' labels rhymed, showing that children monitored speech stream…

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…

Investigated 4-month-olds' responsiveness to others' affective expressions in the context of a peekaboo game. Found differential patterns of visual attention and affective responsiveness to happiness/surprise, anger, fear, and sadness. Findings underscore importance of contextual information for facilitating recognition of emotion expressions and…

When and in what ways do infants recognize humans as intentional actors? An important aspect of this larger question concerns when infants recognize specific human actions (e.g. a reach) as object-directed (i.e. as acting toward goal-objects). In two studies using a visual habituation technique, 12-month-old infants were tested to assess their…

Reports on a portion of a long-term investigation carried out to determine the prognostic significance of newborn behavioral assessments for later development and behavior, in terms of identifying a subpopulation which would be a high risk group. (Author/SDH)

Presented are practical ideas parents can use to prevent and manage excessive crying during their infant's first year. Designed to foster the development of children's physical and emotional independence, the ideas discussed concern (1) the changing functions of crying throughout the infant's first year, (2) causes of crying, (3) the intellectual…

An investigation of Piaget's theory of object concept development through a series of six tasks administered in a combined longitudinal/cross-sectional design (which incorporated a number of methodological controls). Subjects were 36 infants who received the six tasks during each of three testing sessions over a 6-month period. (Author/ED)

Sex differences in the behavior of infants may have the potential for eliciting differential treatment from adults, regardless of whether or not adults consciously intend to encourage sex-differentiated behavior. The role of biologically-based sex differences in partially determining cognitive development is discussed. Availability information is…

The influence of age, sex, representational detail of objects (prototypicality) and adult play suggestions on children's progression of pretend behaviors was studied. A checklist was developed and utilized for coding the responses of 20 children (10 males, 10 females), to objects judged to be high and low prototypical by 12 adults. Children ranged…

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 interim report is part of a longitudinal study of developmental behavior designed to determine whether infants from culturally disadvantaged homes have different developmental patterns than infants from advantaged homes. Twenty six culturally disadvantaged infants were individually evaluated on the Bayley Scale of Infant Mental and Motor…

A study was conducted to measure the degree to which groups of infants could generalize color across objects of different forms and sizes and generalize from across objects of different color and sizes and to see whether color or form would dominate in their generalizations. Ss were 8-13-month-old Caucasian infants. All tests had 16 Ss except the…

Presents a study of decalage between object permanence and person permanence. Decalage was influenced by environmental as well as stimulus factors with infants tested between 6- and 81/4-months/of-age. (BD)
