Vygotsky’s Theory of Cognitive Development
Vygotsky’s Theory of Cognitive Development
Unlike Piaget’s rather individually oriented version of constructivism, some psychologists have focused on the interactions between a learner and more knowledgeable individuals. One early expression of this viewpoint came from Russian Psychologist Lev Vygotsky (1978), whose writing in the 1920s and 1930s focused on how a learner’s thinking is influenced by relationships with others who are more capable, knowledgeable, or expert than the learner. Vygotsky proposed that when a person is learning a new skill or solving a new problem, they can perform better if accompanied and helped by an expert than if performing alone, though still not as well as the expert. Vygotsky’s work was later expanded upon by American psychologist Jerome Bruner (1960), who became convinced that students could usually learn more than had been traditionally expected as long as they were given appropriate guidance and resources. He called such support instructional scaffolding— literally meaning a temporary framework, like one used in constructing a building, that allows a much stronger structure to be built within it. The reason for such a bold assertion was Bruner’s belief in scaffolding—his belief in the importance of providing guidance in the right way and at the right time. When scaffolding is provided, students seem more competent and “intelligent,” and they learn more.
This more social version of constructivism highlights the responsibility of the expert for making learning possible. They must not only have knowledge and skill but also know how to arrange experiences that make it easy and safe for learners to gain knowledge and skill themselves. In addition to knowing what is to be learned, the expert (i.e., the teacher) also has to break the content into manageable parts, offer the parts in a sensible sequence, provide for suitable and successful practice, bring the parts back together again at the end, and somehow relate the entire experience to knowledge and skills already meaningful to the learner.
Modern social learning theories stem from the work of Lev Vygotsky, who produced his ideas as a reaction to existing conflicting approaches in psychology (Kozulin, 1990). Vygotsky’s ideas are most recognized for identifying the role of social interactions and culture in the development of higher-order thinking skills. His theory is especially valuable for the insights it provides about the dynamic “interdependence between individual and social processes in the construction of knowledge” (John-Steiner & Mahn, 1996, p. 192). Vygotsky’s views are often considered primarily as developmental theories, focusing on qualitative changes in behavior over time, that attempt to explain unseen processes of development in thought, language, and higher-order thinking skills. Although Vygotsky’s intent was mainly to understand higher psychological processes in children, his ideas have many practical applications for learners of all ages.
Three themes are often identified with Vygotsky’s ideas of sociocultural learning: (1) human development and learning originate in social, historical, and cultural interactions, (2) the use of psychological tools, particularly language, mediates the development of higher mental functions, and (3) learning occurs within the Zone of Proximal Development. While we discuss these ideas separately, they are closely interrelated.

Sociocultural Theory
Vygotsky’s sociocultural theory emphasizes the importance of culture and social interaction in the development of cognitive abilities. Vygotsky contended that thinking has social origins, social interactions play a critical role especially in the development of higher-order thinking skills, and cognitive development cannot be fully understood without considering the social and historical context within which it is embedded. He explained, “Every function in the child’s cultural development appears twice: first, on the social level, and later, on the individual level; first between people (interpsychological) and then inside the child (intrapsychological)” (Vygotsky, 1978, p. 57). It is through working with others on a variety of tasks that a learner adopts socially shared experiences and associated effects and acquires useful strategies and knowledge (Scott & Palincsar, 2013).
Rogoff (1990) refers to this process as guided participation, where a learner actively acquires new culturally valuable skills and capabilities through a meaningful, collaborative activity with an assisting, more experienced other. It is critical to notice that these culturally mediated functions are viewed as being embedded in sociocultural activities rather than being self-contained. Development is a “transformation of participation in a sociocultural activity” not a transmission of discrete cultural knowledge or skills (Matusov, 2015, p. 315). For example, young children learn problem-solving skills, not by sitting alone at a desk trying to solve arbitrary problems, but by working alongside parents or older siblings as they work on actual culturally-relevant tasks, like preparing a family meal or repairing a fence. Working together, the dyad or group encounter social or physical problems, and discuss their possible solutions before taking action. Through participation in joint problem-solving, young children develop these skills.
The Importance of Interaction: Best Practices Regarding Screen Time
Mobile devices and interactive media have become a part of the everyday lives of children. In fact, we now consider children “digital natives” because they have always been surrounded by mobile and other interactive devices. As a result, parents and professionals who work with children have wondered whether there are any developmental benefits to screen media use by children. Researchers have been exploring this very issue.
Frequent screen use, often defined as more than two hours a day, has been found to have several negative outcomes (Liu et al., 2021). Excessive screen use has been associated with physical, behavioral, and academic problems (Muppalla et al., 2023; Robinson et al., 2017). For example, higher use of screens has been associated with lower cognitive functioning and lower psychological health (Liu et al., 2021). Infants who spend more than fifteen hours per week watching screens are more likely to have delayed vocabulary growth and display attentional problems by the age of six years (Brushe et al., 2024; Duch et al., 2013; Kucker et al., 2024; Sundqvist et al., 2024). Caregivers who indulge in too much screen time are also at risk; parents who ignored infants’ emotional cues to attend to a mobile device were more likely to report that their children had behavioral problems (McDaniel & Radesky, 2018).
One of the essential components of healthy development appears to be human interaction. Research demonstrates that toddlers learn vocabulary better from face-to-face social interactions than from videos (Troseth et al., 2018). When language is presented on a screen, infants learn better in the presence of other infants (Lytle et al., 2018). It is more difficult for infants to fully experience the social cues needed to attract and keep their attention on a screen, and research has shown that screen time is associated with difficulties in learning social skills and reading emotions.
Given these results, what positive outcomes can children experience from screen use? The answer is that it depends in part on how screens are being used. Not surprisingly, the content matters. Potential positive benefits of screen use include opportunities for increased communication and greater access to information and educational opportunities, especially when parents or schools use technology as a learning tool (Panjeti-Madan & Ranganathan, 2023). For example, children can use online encyclopedias and dictionaries to find answers to questions and can maintain social connections with friends who may live far away. Studies have also shown that when screen media is designed to enhance reading and other cognitive skills it may can improve performance (Muppalla et al., 2023).
What does all this tell us about the impact of screen use and interactive media on children? Professionals and caregivers must acknowledge the possible disadvantages of excessive screen use. The American Academy of Pediatrics (AAP, 2021) no longer has strict recommended limits for screen time. Rather, they recommend that parents make an informed decision about how children should use media outside of a school setting, keeping in mind that children need adequate sleep and physical activity. They also advise that media consist of high-quality programming with an educational focus. Parents can manage screen time by setting limits, monitoring content, and encouraging children to use more educational media tools. Finally, caregivers should add alternate activities that allow children to improve their physical, cognitive, linguistic, and socioemotional development in other ways.

Language as a Developmental Tool
In his sociocultural view of development, Vygotsky highlighted the tools that the culture provides to support the development of higher order thought. Chief among them is language. For Vygotsky, children interact with the world through the tool of language. For Piaget, children use schemas that they construct and organize on the mental plane, but for Vygotsky, language, a social medium, was the mechanism through which we build knowledge of the world. He believed that with development, the language we acquire from our environment shapes the ways in which we think and behave. With development, language becomes internalized as thought (i.e., cognition, or reasoning) and children use this internalized language to guide their action.
Scaffolding and the “Zone of Proximal Development”
Vygotsky differed from Piaget in that he believed that a person not only has a set of actual abilities, but also a set of potential abilities that can be realized if given the proper guidance from others. He believed that through guided participation known as scaffolding, with a teacher or capable peer, a child can learn cognitive skills within a certain range known as the zone of proximal development. While both Piaget and Vygotsky highlighted the importance of interactions with the social and physical world as the sources of developmental change, Piaget’s ideas of cognitive development emphasized universal stages progressing toward increasing cognitive complexity. Vygotsky presents a more culturally-embedded view in which situated participatory learning drives development. The idea of learning driving development, rather than being determined by the developmental level of the learner, fundamentally changes our understanding of the learning process and has significant instructional and educational implications.
Have you ever taught a child to perform a task? Maybe it was brushing their teeth or preparing food. Chances are, you spoke to them and described what you were doing while you demonstrated the skill and let them work along with you throughout the process. You gave them assistance when they seemed to need it, but once they knew what to do, you stood back and let them go. This is scaffolding. This approach to teaching has also been adopted by educators. Rather than assessing students on what they are doing, they should be understood in terms of what they are capable of doing with the proper guidance and mentoring.
This difference in assumptions has significant implications for the design and development of learning experiences. If we believe, as Piaget did, that development precedes learning, then we will introduce children to learning activities involving new concepts and problems, but follow their lead, allowing learners to initiate participation when they are ready or interested. On the other hand, if we believe as Vygotsky did that learning drives development and that development occurs as we learn a variety of concepts and principles, recognizing their applicability to new tasks and new situations, then our instructional design will look very different.
Vygotsky and Education
Vygotsky’s theories do not just apply to language development but have been extremely influential for education in general. Although Vygotsky himself never mentioned the term scaffolding, it is often credited to him as a continuation of his ideas pertaining to the way adults or other children can use guidance in order for a child to work within their ZPD. (The term scaffolding was first developed by Jerome Bruner, David Wood, and Gail Ross while applying Vygotsky’s concept of ZPD to various educational contexts.)
Educators often apply these concepts by assigning tasks that students cannot do on their own, but which they can do with assistance; they should provide just enough assistance so that students learn to complete the tasks independently and then provide an environment that enables students to do harder tasks than would otherwise be possible. Teachers can also allow students with more knowledge to assist students who need more guidance. Especially in the context of collaborative learning, group members who have higher levels of understanding can help the less advanced members learn within their zone of proximal development.
