Correct Answer: premeditated stage.
jean piaget, a renowned developmental psychologist, formulated a theory of cognitive development that outlines how children's abilities to think and understand grow through various stages as they mature. according to piaget, this development occurs in a series of four key stages:
1. **sensorimotor stage (0-2 years)**: in this initial phase, infants learn about the world through their senses and actions. they develop an understanding of object permanence—the awareness that objects continue to exist even when they are not visible.
2. **preoperational stage (2-7 years)**: during this stage, children begin to think symbolically and use words or pictures to represent objects. however, their thinking is still not logical and they often struggle with understanding other people's perspectives.
3. **concrete operational stage (7-11 years)**: at this point, children start thinking logically about concrete events. they gain a better understanding of the concept of conservation (the idea that quantity does not change even when its shape does), and they can perform logical operations on concrete objects.
4. **formal operational stage (from about 12 years and up)**: in the final stage of cognitive development, adolescents begin to think abstractly and reason about hypothetical problems. they can conceptualize future possibilities and systematically plan.
now, examining the options provided in your question:
- **concrete operational stage** is indeed one of piaget's stages, focusing on the development of logical thought concerning tangible objects and events.
- **preoperational stage** also correctly corresponds to one of piaget’s stages, where children engage in symbolic play and struggle with taking the perspective of others.
- **sensorimotor stage** correctly represents the first of piaget's stages, where infants use their senses and motor abilities to understand the world.
- **premeditated stage**, however, is not recognized as one of piaget's stages of cognitive development. this term does not appear in piaget's theory and is likely either a distractor or a mistaken term not relevant to his described stages of cognitive development.
therefore, the correct answer to the question "which is not one of piaget’s models of how the mind processes?" is **premeditated stage**, as it does not align with any of piaget's recognized stages of cognitive development.
