For Vygotsky, thought and language are initially separate systems from the beginning of life, merging at around three years of age. At this point speech and thought become interdependent: thought becomes verbal, speech becomes representational. When this happens, children's monologues internalized to become inner speech.
The internalization of language is important as it drives cognitive development. It still remains speech, i. But while in external speech thought is embodied in words, in inner speech words dies as they bring forth thought. Inner speech is to a large extent thinking in pure meanings. Vygotsky was the first psychologist to document the importance of private speech. He considered private speech as the transition point between social and inner speech, the moment in development where language and thought unite to constitute verbal thinking.
Thus private speech, in Vygotsky's view, was the earliest manifestation of inner speech. Indeed, private speech is more similar in its form and function to inner speech than social speech. Private speech is 'typically defined, in contrast to social speech, as speech addressed to the self not to others for the purpose of self-regulation rather than communication.
Unlike inner speech which is covert i. Through private speech, children begin to collaborate with themselves in the same way a more knowledgeable other e. Vygotsky sees "private speech" as a means for children to plan activities and strategies and therefore aid their development.
Private speech is the use of language for self-regulation of behavior. Vygotsky believed that children who engaged in large amounts of private speech are more socially competent than children who do not use it extensively. Children use private speech most often during intermediate difficulty tasks because they are attempting to self-regulate by verbally planning and organizing their thoughts Winsler et al.
The frequency and content of private speech are then correlated with behavior or performance. For example, private speech appears to be functionally related to cognitive performance: It appears at times of difficulty with a task. Berk provided empirical support for the notion of private speech. She found that most private speech exhibited by children serves to describe or guide the child's actions.
Berk also discovered than child engaged in private speech more often when working alone on challenging tasks and also when their teacher was not immediately available to help them. Furthermore, Berk also found that private speech develops similarly in all children regardless of cultural background. This hypothesis is supported by the fact that there exist high positive correlations between rates of social interaction and private speech in children.
Children raised in cognitively and linguistically stimulating environments situations more frequently observed in higher socioeconomic status families start using and internalizing private speech faster than children from less privileged backgrounds.
Indeed, children raised in environments characterized by low verbal and social exchanges exhibit delays in private speech development. This is due to changes in ontogenetic development whereby children are able to internalize language through inner speech in order to self-regulate their behavior Vygotsky, Vygotsky's approach to child development is a form of social constructivism , based on the idea that cognitive functions are the products of social interactions.
Vygotsky emphasized the collaborative nature of learning by the construction of knowledge through social negotiation. He rejected the assumption made by Piaget that it was possible to separate learning from its social context. Vygotsky believed everything is learned on two levels. A contemporary educational application of Vygotsky's theory is "reciprocal teaching," used to improve students' ability to learn from text.
In this method, teachers and students collaborate in learning and practicing four key skills: summarizing, questioning, clarifying, and predicting. The teacher's role in the process is reduced over time. Also, Vygotsky theory of cognitive development on learners is relevant to instructional concepts such as "scaffolding" and "apprenticeship," in which a teacher or more advanced peer helps to structure or arrange a task so that a novice can work on it successfully. Vygotsky's theories also feed into the current interest in collaborative learning, suggesting that group members should have different levels of ability so more advanced peers can help less advanced members operate within their ZPD.
Vygotsky's work has not received the same level of intense scrutiny that Piaget's has, partly due to the time-consuming process of translating Vygotsky's work from Russian. Also, Vygotsky's sociocultural perspective does not provide as many specific hypotheses to test as did Piaget's theory, making refutation difficult, if not impossible.
Perhaps the main criticism of Vygotsky's work concerns the assumption that it is relevant to all cultures. Rogoff dismisses the idea that Vygotsky's ideas are culturally universal and instead states the concept of scaffolding - which is heavily dependent on verbal instruction - may not be equally useful in all cultures for all types of learning. Indeed, in some instances, observation and practice may be more effective ways of learning certain skills.

Initially, this behavior begins as a meaningless grasping motion; however, as people react to the gesture, it becomes a movement that has meaning.
In particular, the pointing gesture represents an interpersonal connection between individuals. Application This is a general theory of cognitive development.
