Jean Piaget, one of the most influential researchers in the study of cognitive development, believed that children's thinking changes in important ways as they move from the preschool years into middle childhood. This transition from preoperational thought to concrete operational thought involves the development of what Piaget called mental operations, which are logical principles of reasoning.
Piaget's most well-known task for measuring this transition is the liquid quantity problem. In this task, a child is shown two identical glasses, each with identical amounts of liquid in them. After the child agrees that the amount of liquid in the two glasses is equivalent, the researcher pours the liquid from one of the glasses into a tall, narrow glass. Because the level of the liquid in the tall glass is now higher than the liquid level in the original glass, most young children in the preoperational stage say that the tall glass has "more."
Play the video to view the response of a typical preoperational child.
As you can see, young children fail to conserve the equivalence of the two amounts of liquid. They focus on the change in appearance, and they do not realize that the amount of liquid in the two different shaped glasses remains the same.
As children move into the concrete operational stage of thinking, they begin to realize that the transformation in the appearance of the liquid does not change the amount of liquid. In other words, they demonstrate an understanding of conservation.
What has changed in their thinking? Piaget believed that the child could correctly solve the liquid quantity problem by applying any one of three logical operations to the situation:
1. Identity: Since nothing has been added and nothing has been taken away, the amount must still be the same and identical to the amount in the original glass.
2. Reversibility: Although pouring the liquid into the tall, thin glass changes the appearance of the liquid, the child can imagine the liquid being poured back into the normal glass.
3. Reciprocity: The level of liquid is higher in the tall glass, but the glass is narrower. The increase in height is compensated by a reciprocal decrease in width so the amount must still be the same.
Play the video to observe the response of a concrete operational child. Can you determine which reasoning she is using?
Piaget argued that the failure of a young child to demonstrate conservation could be explained as a problem of centration, the focusing on one dimension of the problem and the ignoring of the other dimensions. In this case, the young child centers or focuses on the height of the water in the glass and fails to consider the width of the glass.
Therefore, an older child who can pass this task and demonstrates an understanding of conservation is moving toward decentration. Piaget believed that decentration is an important part of cognitive development from middle childhood through adolescence as it allows children to gradually develop the mental operations that will enable them to take more and more aspects of the situation into account when solving a problem. Viewed in this way, decentration is good preparation for the complexities of adult life!

The science of human development seeks to understand how and why people (all kinds of people, everywhere) change or remain the same over time. The scientific study of human development, including that of children and adolescents, is based on empirical evidence rather than on theory. Any view of human development is inherently influenced by subjective perceptions because the study of human development is humans studying other humans! Scientific research attempts to parse subjective opinions and empirical findings (Lerner, 2006).
To attempt to deal with the distortions of personal opinions and biases, researchers rely on the scientific method, a technique for answering questions that requires empirical research and data-based conclusions. The scientific method includes four steps:
1. Ask a question.
2. Develop a hypothesis, which is a specific prediction to be tested.
3. Test the hypothesis to provide empirical evidence about the validity or falsehood of the hypothesis.
4. Draw conclusions to support or refute the hypothesis.
Many of the research questions presented by those who study children and adolescents are inspired by or nested within developmental theories. These theories connect facts and observations with patterns and explanations. They guide hypotheses, generate discoveries, and often provide the basis of practice guidance.
At the heart of many developmental theories is the nature versus nurture controversy that focuses on whether heredity (nature) or the environment (nurture) has a greater influence on a particular feature of development. The view has swung back and forth over time regarding the amount of influence that either nature or nurture has on a wide range of developmental traits. Today, it is commonly accepted that most aspects of a child's or adolescent's development are products of the interaction of both nurture and nature. Advocates of each side of this question introduce theories for how either nature or nurture impacts development (Clark, 2003). Consider how these different advocates would explain children's language acquisition, which is the process by which language capacity develops in a child.
As an introduction to the topic of language acquisition, play the two videos on this screen.
A major proponent of the position that language acquisition depends largely on environment (nurture) was the behaviorist B. F. Skinner, who theorized that language is acquired through principles of conditioning, including association, imitation, and reinforcement (Skinner, 1957). According to this view, children learn words by associating sounds with objects, actions, and events as well as by imitating others. In particular, adults play an important role in language acquisition by speaking to children in a slow, grammatical, and repetitive way. In turn, children discern patterns in language and experiment with speech gradually through interaction with their speaking world.
Although nurture may have historically referred primarily to the care given to children by their caregivers, it has been suggested more recently that any non-genetic environmental factor could also be considered as nurture in a contemporary nature versus nurture debate. This broader definition of nurture may include influences from childhood friends, early experiences with media of all types, and even incidents in the womb (Lust & Foley, 2004).
Play the video clip to explore how children learn to communicate and to speak with such fluency and competence.
Noam Chomsky theorizes that parts of the brain have evolved over time specifically for the purpose of producing, organizing, and understanding language. According to this theory, there is an assumption that all languages have a common, essential structural basis and set of rules and that children are born with an innate propensity for language acquisition. This propensity allows children to decipher what is and is not possible in the grammar of their native language and to master that grammar by the age of about three years old. This inborn ability to grasp the rules of language is known as universal grammar. Today, researchers continue to theorize about how language evolves.
Before the 1970s, most deaf children in Nicaragua were homebound and isolated from others who could not hear. In 1981, a vocational school opened in Managua, and deaf children were permitted to attend. Upon exposure to their deaf peers, these previously secluded children began to communicate with one another using a rudimentary set of gestures. With each generation of students, these gestures evolved from crude and pantomime-like movements into a more sophisticated sign language (referred to as Nicaraguan Sign Language or NSL). In spite of its organic evolution in a rather insular community, NSL demonstrates characteristics found in nearly all other spoken and signed languages.
Dr. Ann Senghas and her colleagues (2004) reported that the deaf Nicaraguan children at the Managua school developed distinct signs to signify movement and direction. This distinction is especially significant because this child-created sign language mirrors a distinction that also appears in spoken language. Based on her research, she concluded that these children instinctively broke information into small chunks for signing. This strategy provided great flexibility. The deaf students were able to string these small chunks back together in order to form sentences with a wide range of meaning. This feature of the spontaneously-generated NSL is similar to all spoken and signed languages throughout the world. Her findings suggest that there is an instinctive component to the way in which language is learned.
