What is thinking?
Thinking is a mental activity through which people manipulate information, form concepts, draw inferences, solve problems and make decisions. It can use images, words, symbols and actions. Thinking is influenced by prior knowledge and the situation, so two people may approach the same problem differently.
Concepts and categories
A concept groups objects, events or ideas that share features. Categories help organise knowledge and make recognition faster. Typical examples are often easier to identify than unusual members, but category boundaries can be flexible.
Reasoning and problem-solving
Reasoning uses information to reach a conclusion. Deductive reasoning moves from a general rule to a particular conclusion; inductive reasoning builds a broader conclusion from examples and therefore remains open to revision. A problem-solving sequence can include identifying the goal, representing the problem, generating options, evaluating them, acting and reviewing the result.
People may use algorithms, which follow a defined sequence and can be reliable but slow, or heuristics, which are shortcuts that are efficient but can produce errors. Functional fixedness and mental set can constrain solutions when a person sees an object or strategy only in its familiar use.
Decision-making
Decision-making involves choosing among alternatives. People weigh goals, evidence, expected outcomes and constraints, but decisions may also be affected by framing, incomplete information and prior beliefs. A sound answer identifies the options and criteria rather than claiming that people always make perfectly rational choices.
Creative thinking
Creative thinking produces ideas or products that are both original and useful in a context. Divergent thinking generates several possibilities; convergent thinking evaluates and refines them. Practice, subject knowledge, willingness to reconsider assumptions and a supportive environment can all contribute.
Key terms
Concept: a mental category. Reasoning: drawing conclusions from information. Algorithm: a stepwise procedure. Heuristic: a practical shortcut. Functional fixedness: difficulty seeing a familiar object in a new use. Divergent thinking: generating multiple possible ideas.
Practice questions
