    Sensorimotor
  • b)
    Preoperational
  • c)
    Concrete-operational
  • d)

Verified Answer
A group of children tasked with arranging a set of colored blocks from...
Jean Piaget, a Swiss psychologist, has made a systematic study of cognitive development in his theory that is categorized in four stages. 
  • He observed his children and their process of making sense of the world around them and developed a model of how the mind processes new information encountered.
Key Points
  • The children in the described scenario, are in Piaget’s Concrete-operational stage and showing the ability of seriation.
  • It is the ability to order items along a particular dimension such as length or weight. For instance, arranging block from shortest to lightest to the heaviest.
  • Interestingly, children can also seriate mentally, that is, they are capable of transitive inference. If Block A is lighter than Block B, and Block B is lighter than Block C, children can draw the mental inference that Block C is the heaviest.
Hence, the children are in Piaget’s
 
Concrete-operational stage

Understanding Piaget’s Concrete-Operational Stage
The correct answer is option 'C', indicating that the children are in Piaget’s Concrete-Operational stage of cognitive development, typically occurring between ages 7 and 11.

Characteristics of the Concrete-Operational Stage
- Children in this stage can perform logical operations and think systematically about concrete objects and events.
- They gain the ability to classify objects, understand the concept of reversibility, and develop the ability to organize items based on attributes such as weight and color.

Logical Reasoning and Inference
- The children’s task of arranging blocks from lightest to heaviest demonstrates their ability to understand and manipulate concrete properties.
- Their capacity to infer relationships, as seen in the question about Block A, Block B, and Block C, showcases their developing logical reasoning skills.

Comparison with Other Stages
- In contrast, the Preoperational stage (option B) is characterized by egocentrism and difficulty in understanding the perspective of others, lacking the ability to perform logical operations.
- The Sensorimotor stage (option A) involves learning through sensory experiences and motor actions, without the ability to think abstractly.
- The Formal Operations stage (option D) begins around age 12, where abstract thinking and hypothetical reasoning become possible, which is not yet fully developed in the children described.

Conclusion
The children’s ability to sort blocks by weight and engage in logical inference indicates they are firmly in the Concrete-Operational stage, capable of concrete reasoning and logical thought regarding tangible objects.
