We explain what cognitive development is and what Piaget's Theory consists of. Also, the four stages of cognitive development.
What is cognitive development?
When we speak of cognitive development, we refer to the various stages that consolidate the innate capacity of the human being to think, reason and use your mental tools. Is a process gradual, which has its beginnings in early childhood, and which motivates the desire of the individual to understand their environment and integrate into the society.
The students of this process separate and delimit its progressive stages, in order to understand at what point in life certain are acquired skills mental. In this, of course, the objective conditions (physical, social, emotional) in which the individual develops. This specific growth in capabilities is known ascognitive learning.
In the description From these stages, various scholars such as Jean Piaget, Toldan, Gestalt and Bandura have proposed their approaches to a scientific system that understands them. The best known is perhaps theTheory of cognitive development by the Swiss Piaget, which serves as the basis for various educational approaches focused on the enrichment of the childhood experience or "open education".
Piaget's theories contributed not only in this field, but also in the understanding of human intelligence, learning and the various forms of thought.
Piaget's theory
Piaget proposed his theory on the nature and development of human intelligence in the mid-twentieth century, and revolutionized the understanding of it. According to its postulates, the development cognitive occurs through a series of different and recognizable stages, the beginning of which occurs in childhood and requires perception, adaptation and manipulation of the environment, as the infant actively explores the world.
The four stages of cognitive development proposed by Piaget are:
- Sensory-motor or sensorimotor stage. The initial phase of the process, which begins the birth and culminates the appearance of the language simple articulated (around two years of age). It is an exploratory stage, in which the individual tries to collect as much as possible from his interaction with the environment, either through games, movements not always voluntary, and an egocentric consideration of the universe divided between the "I" of the subject and "the environment." At this stage it is also learned that the objects of the world, even if they are not clearly differentiated, remain even though we are not seeing them.
- Pre-operational stage. This second stage takes place between the ages of two and seven, and is characterized by the learning of fictitious roles, that is, the possibility of putting oneself in someone else's place, of acting and of using objects of a symbolic nature. Abstract thinking remains difficult, as is logical thinking, and instead magical thinking is prevalent.
- Stage of concrete operations. Between the ages of seven and twelve, this is the stage when the logical thinking it begins to lead to valid conclusions, even if the most complex degrees of abstraction may be difficult. A certain tendency to egocentrism in the individual.
- Stage of formal operations. The last of the stages of cognitive development, between twelve years and adulthood, is the period in which the individual acquires the ability to handle abstract thinking, being able to obtain valid conclusions from completely hypothetical situations, not lived, achieving thus to think about thinking, that is, to achieve metaphysical thought and reasoning hypothetical deductive.
We must note that, although they are explained linearly, these stages do not occur separate from each other, nor as perfectly defined steps, but rather that the transit between one and the other is diffuse, varying according to the case.
