Peekaboo is thought by developmental psychologists to demonstrate an infant's inability to understand object permanence. [5] Object permanence is an important stage of cognitive development for infants. In early sensorimotor stages, the infant is completely unable to comprehend object permanence.
Peek-a-boo is a prime example of an object permanence test. [6] In Piaget's formulation, there are six stages of object permanence. [7] These are: 0–1 months: Reflex schema stage – Babies learn how the body can move and work. Vision is blurred and attention spans remain short through infancy.
Moreover, Piaget claimed that cognitive development is at the centre of the human organism, and language is contingent on knowledge and understanding acquired through cognitive development. [6] Piaget's earlier work received the greatest attention. Child-centred classrooms and "open education" are direct applications of Piaget's views. [7]
Since Piaget's contribution to the field, infant cognitive development and methods for its investigation have advanced considerably, with numerous psychologists investigating different areas of cognitive development including memory, language and perception, coming up with various theories [4] —for example Neo-Piagetian theories of cognitive ...
While applying the Bayley Scales of Infant Development (BSID-II), it was found that scales may lead to under-estimates of cognitive abilities in infants with Down syndrome. [7] Researchers excluded a number of items that implicated language, motor , attentional and social functioning from the original measures the modified form was administered ...
The incidence and quality of physical activity education in early childhood education have a strong positive effect on the cognitive, social and physical development of young children. [12] Early childhood is a stage of rapid growth, development and learning and each child makes progress at different speeds and rates. [ 13 ]
The development of the human mind is complex and a debated subject, and may take place in a continuous or discontinuous fashion. [4] Continuous development, like the height of a child, is measurable and quantitative, while discontinuous development is qualitative, like hair or skin color, where those traits fall only under a few specific phenotypes. [5]
Piaget came up with a theory for developmental psychology based on cognitive development. Cognitive development, according to his theory, took place in four stages. [ 1 ] These four stages were classified as the sensorimotor, preoperational, concrete operational and formal operational stages.
