How Do Children Acquire Knowledge: Exploring the Role of Logical Reasoning
Introduction
During childhood, we go through a remarkable process of learning to speak and acquiring knowledge about the world around us. While social interactions and educational environments play crucial roles in this development, recent research suggests that natural logical reasoning also contributes significantly to the learning process. A study conducted by the UPF Brain and Cognition Center sheds light on the presence of logical reasoning in children as young as 19 months old, independent of their language knowledge.
The Question of Logical Reasoning in Preverbal Children
Neuroscientists have long debated whether preverbal babies possess the ability to engage in logical reasoning. The groundbreaking research conducted by the UPF Brain and Cognition Center indicates that infants as young as 19 months show evidence of natural logical reasoning that doesn’t rely on language knowledge. This discovery challenges previous assumptions and highlights the development of logical thinking from an early age.
The Exclusion-by-Elimination Strategy
The researchers found that young children employ a strategy called “exclusion-by-elimination” to make deductions and reach conclusions about unknown realities. When faced with unfamiliar situations, children analyze the options available to them and systematically eliminate the options that are not possible based on their level of knowledge. This logical reasoning process occurs instinctively, even in the absence of language comprehension.
Two Strategies for Resolving Uncertainties
The study delves into the significance of two strategies used by babies to tackle uncertainties: association and exclusion. The association strategy involves mentally linking a new word to both unfamiliar objects and subsequently associating it with the object that best fits the word. On the other hand, the exclusion strategy revolves around deducing the meaning of a new word by eliminating alternatives. By ruling out options based on prior knowledge, young children can infer the correct association.
Experimental Evidence of Natural Logic
In order to explore the natural logic of young children, the research team conducted two experiments involving both monolingual and bilingual infants. The first experiment required participants to associate words with familiar and unfamiliar objects, testing their ability to make logical deductions. The second experiment involved determining which object was hidden from view based on auditory cues, further assessing the children’s grasp of logical reasoning.
Findings and Implications
The results of the study demonstrate that monolingual and bilingual young children exhibit similar levels of logical reasoning, indicating that linguistic experience does not significantly impact this cognitive ability. This finding has important implications for understanding the early development of logical thinking and suggests that it is present from a young age. While the study focused on 19-month-old infants, further research may reveal the presence of natural logical thought at even earlier stages of development.
Expanding Our Understanding
Beyond the research findings, there are several additional insights and perspectives to delve into when exploring how children acquire knowledge and develop logical reasoning abilities:
- The Role of Curiosity: Curiosity plays a vital role in a child’s exploration of the world. By naturally questioning and seeking answers, children engage in logical thinking processes that enhance their understanding of the environment.
- Problem-Solving Skills: Logical reasoning is closely related to problem-solving abilities. As children encounter challenges or puzzles, they apply their logical thinking skills to identify patterns, make connections, and find solutions.
- Cultural and Environmental Influences: While the study presented here emphasizes the universality of logical reasoning among young children, it is essential to acknowledge the influence of cultural and environmental factors. Societal norms, educational practices, and linguistic diversity can shape the development and application of logical thinking.
- Supportive Learning Environments: Creating environments that foster logical reasoning skills can have a profound impact on a child’s cognitive development. Providing opportunities for open-ended play, problem-solving tasks, and critical thinking exercises can nurture and enhance logical thinking abilities.
- Long-Term Implications: Understanding how children acquire knowledge and develop logical reasoning skills can have long-term implications for education and cognitive development. By recognizing the innate capacity for logical thinking, educators can better design learning strategies and interventions to optimize children’s intellectual growth.
Conclusion
The study conducted by the UPF Brain and Cognition Center sheds light on the early emergence of logical reasoning in young children. The ability to make deductions and draw conclusions from limited information is present at least by 19 months of age and does not depend on language knowledge. These findings challenge traditional assumptions about the relationship between language acquisition and logical thinking, highlighting the intrinsic nature of logical reasoning in early cognitive development. Further research in this field can deepen our understanding of how children acquire knowledge and provide valuable insights for educators and parents alike.
Summary
A study led by the UPF Brain and Cognition Center reveals that young children, as young as 19 months old, demonstrate natural logical reasoning abilities that do not rely on language knowledge. The research highlights the existence of a natural logical thought process that operates through the exclusion-by-elimination strategy, where children analyze and eliminate options to reach conclusions about unfamiliar realities. The study found no significant differences in the logical reasoning abilities between monolingual and bilingual children, demonstrating that it is not dependent on linguistic experience. Understanding how children acquire knowledge and develop logical reasoning skills can have profound implications for education and cognitive development.

How do we learn to speak during childhood or how do we acquire knowledge about the world around us? Young children’s social interactions in their social and family environment and in schools help explain this, but they are not the only factors involved. Natural logical thinking, which manifests itself from a very early age and does not depend on knowledge of language, also facilitates the learning process, according to a study led by the UPF Brain and Cognition Center, the results of which were published this Friday. September 1, in the magazine current biology.
The study focuses on a question that is still being debated among neuroscientists: whether babies who have not yet learned to speak (or are developing speech) are capable of logical reasoning. This pioneering research demonstrates that this natural logical reasoning exists from at least 19 months of age, does not depend on language knowledge, and develops primarily through the exclusion-by-elimination strategy. That is, if young children are faced with an unknown reality, they would try to analyze it and reach some conclusion about it, ruling out the options that are not possible, according to their level of knowledge at that moment.
The results of the work are presented in the article entitled The scope and role of deduction in infant cognition, written by Kinga Anna Bohus, Nicolo Cesana-Arlotti, Ana Martín-Salguero and Luca Lorenzo Bonatti. The main researcher, L. Bonatti (ICREA), is the director of the Reasoning and Child Cognition (RICO) research group at the UPF Center for Brain and Cognition (CBC). Kinga Anna Bohus (lead author) is also a member of the group. N. Cesana-Arlotti and Ana Martín-Salguero, previously linked to the CBC of the UPF, are currently researchers at Yale University (USA) and at the École Normale Supérieure in Paris.
Young children tend to resolve uncertainties by discarding impossible options depending on the level of knowledge they have at each moment.
The study analyzes the importance of two strategies for babies to face uncertainties: association and exclusion (or elimination of disjunction). The first strategy would mean that young children, upon hearing a new word that can refer to two unfamiliar objects they can see, mentally associate the term with each of them. Subsequently, they would associate the term with the object with which that name best fits.
The second strategy (exclusion) explains how a young child can learn a new word through logical reasoning by eliminating alternatives. For example, if they see two objects (A and B) and hear an unknown term that they know is not A (because they know the name of A), they will determine that it is the name of B. This is the prevailing strategy. , according to the results of the study.
Two experiments to analyze the natural logic of young children posed with known and unknown objects and terms
The research team conducted two different experiments, the first with 61 monolingual (26) and bilingual (35) 19-month-old children and the second with 33 (19 monolingual and 14 bilingual). The analysis of each group was crucial to determine if the deductive processes depend on the linguistic experience.
In the first experiment, the participants were shown two objects, which they had to associate with one of the words they heard, using different tests. In the first test, they had to look at two familiar objects (eg, a spoon and a cookie) and, upon hearing a term (eg, spoon), associate it with one of the two. In the second trial, infants were shown a familiar object (eg, apple) and an unfamiliar object (eg, carburetor), and heard the word corresponding to the familiar object (apple). ), which they had identify. The third trial was the same as the second, except that the word heard corresponded to the unknown word (for example, carburetor).
In the second experiment, two objects or animated beings were used (for example, an umbrella and the figure of a child), each associated with a sound. Subsequently, the two objects were covered so that the infant could not see them and one of them was placed in a glass. When they were uncovered, the boy could only see one of the two objects and had to guess, by elimination, which one was inside the glass. In a subsequent test (with the two objects covered and without changing their position), the baby listened to the sound associated with one of them and was tested whether she was looking in the direction of the correct object.
In all these tests, their gaze movement patterns were evaluated. For example, when reasoning by exclusion, young children look at object A and, if they rule out that the term they have heard refers to it, then they look at object B. This is known as a double-check strategy.
There are no relevant differences in the logic of monolingual and bilingual young children.
Lead author of the research, Kinga Anna Bohus, summarizes the main results of the study as follows: “We studied the presence of the concept of logical disjunction in 19-month-old infants. In a word reference mapping task, both bilingual and Monolingual infants display a pattern of oculomotor inspection that was previously considered a hallmark of disjunctive reasoning in adults and children.”
In short, the results of the study do not show relevant differences between the logical reasoning of monolingual and bilingual children, which confirms that it does not depend on linguistic knowledge. This natural logical thought could be present before 19 months, although there is still not enough scientific evidence to demonstrate its presence at earlier ages.
