Context This lesson is the first of a two-part series aimed at introducing students to the different stages of physical growth and development in human beings from birth to 18 years of age. In these lessons, students become familiar with the four key periods of growth and human development: For each stage of development, they learn about key physical stages or milestones, which are research and science-supported indicators that help to track the progress of a child's physical development at different stages of life. Conversely, they also learn that it is very natural and normal for children to reach these markers at different times.
Size and Shape Constancy: To accurately perceive objects, we must translate changing retinal images into a single representation. Size constancy is the perception that an object's size is the same, despite changes in its retinal image size. Shape constancy is perception that an object's shape is stable, despite changes in the shape projected on the retina.
Both of these perceptual capacities appear to be innate and assist babies in detecting a coherent world of objects. Perception of Objects as Distinct, Bounded Wholes: The movement of objects relative to one another and to their background enables infants to construct a visual world of separate objects.
At first, motion and spatial arrangements help infants identify objects. Intermodal perception combines information from more than one modality, or sensory system. Recent evidence indicates that babies perceive the world in an intermodal method from the beginning.
Key Piagetian Concepts 1. Piaget believed children move through four stages of development between infancy and adolescence.
During the sensorimotor stage, infants and toddlers "think" with their eyes, ears, hands, and other sensorimotor equipment. What Changes With Development: Piaget believed a child's schemes change with age.
Schemes are action-based at first and later will move to a mental level. How Cognitive Change Takes Place: Organization 1 Organization is an internal process of rearranging and linking together schemes to form an interconnected cognitive system. The Sensorimotor Stage 1.
Piaget based the sensorimotor stage on his observations of his own children.
These reactions are first centered on the infant's own body. Reflexive Schemes - a. Piaget regarded newborn reflexes as the building blocks of sensorimotor intelligence.
At first, babies suck, grasp, and look in much the same way, no matter what the circumstances. Infants develop simple motor skills and change their behavior in response to environmental demands.
The first circular reactions are primary in that they are oriented towards the infants' own bodies and motivated by basic needs. Circular reactions of this substage are secondary in that the infants repeat actions that affect the environment. Infants can imitate actions that they have practiced many times.
Coordination of Secondary Circular Reaction - a.
Intentional, or goal directed, behavior is the combination of schemes to solve problems. Piaget regarded mean send action sequences as the first sign that babies appreciate physical causality. Object permanence is the understanding that objects continue to exist when they are out of sight; it is not yet complete in this substage.
AB search errors are committed by infants in this substage. Infants 8- to months-old only look for an object in hiding place A after the object is moved from A to hiding place B.
Experimentation leads to a more advanced understanding of object permanence. Toddlers no longer make the AB search error. Mental representations are internal images of absent objects and past events. The toddler can now solve problems through symbolic means instead of trial-and-error.
Representation allows deferred imitation-the ability to copy the behavior of models who are not immediately present. Functional play is motor activity with or without objects during the first year and a half in which sensorimotor schemes are practiced.
At the end of the second year, representation permits toddlers to engage in make-believe play.Spanish-English English-Spanish Italian-English English-Italian English-French French-English English definition English synonyms Español-Français Español-Português Français-Español Português-Español Español: definición Español: sinónimos Español: gramática Català: definició more.

There are multiple areas of growth and development that occur throughout infancy and early childhood. Cognitive development refers to brain development and the capacity for learning. Psychosocial and emotional development are terms that refer to a person's social and emotional growth. Stages of Human Development.
