The author presents an overview of Pascual-Leone's Theory of Constructive Operators, a process-structural theory based upon Piagetian constructs which has evolved to both explain and predict the temporal unfolding of behavior. An application is made of the theory to the demands of a discrete motor task and prediction of (a) the minimal age…

This paper elucidates the implications of life-span developmental psychology for theory and method in the field of child development. Emphasis is given to three theoretical issues: (1) historical-evolutionary versus ontogenetic components of change, (2) the role of chronological age, and (3) continuity versus discontinuity in the description and…

This document presents an analysis of the early attending responses and orienting reactions of infants which can be observed at birth and shortly thereafter. Focus is on one specific orienting reaction, the early direction and maintenance of one's eyes and head toward certain stimuli instead of others. The physical properties of stimuli that…

Resilience is the ability to thrive, mature, and increase competence in the face of adverse circumstances. Recent research has uncovered personal and environmental characteristics that contribute to resilience during infancy and toddlerhood, as well as characteristics that predict resilience in later years. Resilient infants and toddlers are…

The Nurse-Parent Training Project, developed in cooperation with Children's Hospital of Buffalo (New York), was designed to provide developmental supportive care for premature infants, and to reduce stress while optimizing neurobehavioral development. A program was conducted to train nurses working in neonatal intensive care nurseries, to enable…

During an experiment on infant behavior, it was observed that young children shared toys with their mothers; therefore, a series of research studies was designed to investigate this phenomenon. The general purposes of the research were: (1) to define sharing more precisely and develop objective measures of frequency and duration for it, (2) to…

Three studies examined proximity and contact behaviors (behaviors generally thought to be indicative of attachment relationships) in young autistic children. The first study examined the behavior of 32 young autistic children and children with pervasive developmental disorders (PDD) in a "strange situation" paradigm using four…

This paper presents observational and research evidence to refute two widely held beliefs about psychological development: the belief in predetermined development and the belief in the simultaneous development of all behavioral systems. Studies suggesting the plasticity of development through environmental deprivation and intervention are…

This paper discusses issues connected with the reliability of the Neonatal Behavioral Assessment Scale (NBAS) in terms of behavior prediction, neonatal behavioral organization and stability, and consequent implications for study of newborns. Discussion focuses on: (1) reliability, and (2) prediction and neonatal assessment. The NBAS is seen as a…

Human development from about ages 2 to 5 is presented in terms of the history of a child conceptualized in terms of stimulus and response functions and his interactions in current situations which consist of organismic, physical, and social conditions. The concepts describing the changes that occur during this developmental period, such as…

This paper reviews evidence obtained from an analysis of the behavior of 3 to 11 year olds as observed in natural settings in the six culture study and preliminary findings from observing the behavior of mothers and children in a variety of settings in Kenya. The definition of "modern" includes at least three separate indices--the…

An understanding of the stages involved in children's development of sensory motor integration would aid in the creation of instructional strategies in physical education. These strategies would optimize both the child's physical coordination and creative development by increasing the correlation between the demands of a learning environment and…

The paper presents key features of Jean Piaget's theory of moral development, compares Piaget's theory with Lawrence Kohlberg's theory of moral development and Sidney Simon's theory of values clarification, and evaluates the values clarification movement in light of Piaget's theoretical and practical conclusions. The focus is twofold: first, on…

This paper deals with the role of the child developmentalist in improving interdisciplinary assessment and treatment of children with behavioral and learning problems. A specific task of Developmental Services of the Texas Research Institute of Mental Sciences was to optimize the utilization of professional staff in a development assessment…

This study explored the inter-relationships and developmental stability of inhibitory motor control, attentional control, delay of gratification, and resistance to temptation with 32 preschool children, and related these components of self-regulation to children's behavior at home and in the classroom. The children completed the T.O.V.A.…
