Chapter 7: Thinking
Unit VII – Thinking (5 Marks)
7.1 Introduction
Thinking is a higher-order mental process that involves the manipulation of mental representations (images, concepts, propositions) to reason, solve problems, make decisions, and create new ideas.
Thinking goes beyond perception and memory — it allows us to go beyond the information given to us and imagine, plan, create, and evaluate.
7.2 Nature of Thinking
| Feature | Description |
|---|---|
| Cognitive | Involves internal mental processes |
| Symbolic | Uses symbols (words, images, concepts) to represent objects and events |
| Goal-directed | Usually aimed at solving a problem or reaching a decision |
| Constructive | We actively build and manipulate mental representations |
| Beyond perception | Can deal with absent, abstract, or hypothetical objects |
7.2.1 Building Blocks of Thought
Thinking relies on three basic mental building blocks:
| Building Block | Description | Example |
|---|---|---|
| Mental images | Mental pictures or representations of sensory experiences | Imagining the face of a friend |
| Concepts | Mental categories that group objects, events, or ideas that share common properties | “Fruit” groups apples, bananas, etc. |
| Propositions | Statements that relate concepts and express a unit of meaning | “The cat is on the mat” |
Concepts
Concepts are essential for thinking because they help us organise, simplify, and make sense of the vast amount of information we encounter.
| Type | Description | Example |
|---|---|---|
| Natural concepts | Formed through everyday experience; fuzzy boundaries | “Bird” — robins are typical; penguins are atypical |
| Artificial (formal) concepts | Defined by a specific set of rules or features | “Triangle” — must have 3 sides and 3 angles |
| Prototype | The most typical or representative example of a concept | A “robin” is the prototype of “bird” for many people |
7.3 The Processes of Thinking
Thinking involves several interrelated processes:
7.4 Problem Solving
Problem solving occurs when there is a gap between a current state and a desired goal, and the solution path is not immediately obvious.
Steps in Problem Solving
- Identify the problem — Understand what the problem is
- Represent the problem — Create a mental representation
- Plan a solution — Generate possible strategies
- Execute the plan — Carry out the strategy
- Evaluate the result — Assess whether the goal has been achieved
Strategies for Problem Solving
| Strategy | Description |
|---|---|
| Trial and error | Trying different solutions randomly until one works |
| Algorithm | A step-by-step procedure that guarantees a solution (but may be slow) |
| Heuristic | A “rule of thumb” or mental shortcut that may lead to a solution quickly but doesn’t guarantee success |
| Insight | Sudden realisation of the solution (the “aha!” moment) |
| Analogy | Using a solution from a similar, previously solved problem |
Obstacles to Problem Solving
| Obstacle | Description |
|---|---|
| Mental set | Tendency to use a previously successful strategy even when it is no longer effective |
| Functional fixedness | Inability to see an object as having a function other than its usual one (e.g., not thinking to use a coin as a screwdriver) |
| Confirmation bias | Tendency to seek information that confirms existing beliefs and ignore contradictory evidence |
7.5 Reasoning
Reasoning is the process of drawing conclusions from available evidence or premises.
Types of Reasoning
| Type | Direction | Description | Example |
|---|---|---|---|
| Deductive reasoning | General → Specific | Starting from general principles to reach a specific conclusion | All mammals are warm-blooded. A dog is a mammal. Therefore, a dog is warm-blooded. |
| Inductive reasoning | Specific → General | Drawing a general conclusion from specific observations | Every swan I’ve seen is white. Therefore, all swans are white. (May be wrong!) |
Key difference: Deductive conclusions are certain (if premises are true). Inductive conclusions are probable but not certain.
Common Errors in Reasoning
- Availability heuristic — judging probability based on how easily examples come to mind (overestimating plane crash risk after news coverage)
- Representativeness heuristic — judging based on resemblance to a typical case (assuming someone who loves books is a librarian, not a farmer)
- Anchoring — being overly influenced by the first piece of information encountered
7.6 Decision-Making
Decision-making involves choosing between alternatives based on evaluation of available information.
Factors Affecting Decision-Making
| Factor | Effect |
|---|---|
| Available information | More relevant information usually leads to better decisions |
| Framing | How a problem is presented influences the choice (e.g., “90% survival rate” vs. “10% mortality rate”) |
| Emotions | Strong emotions can impair or enhance decision-making |
| Cognitive biases | Mental shortcuts (heuristics) can lead to systematic errors |
| Time pressure | Urgency may lead to reliance on heuristics rather than careful analysis |
7.7 Nature and Process of Creative Thinking
7.7.1 Nature of Creative Thinking
Creativity is the ability to produce ideas or solutions that are both novel (new, original) and useful (appropriate, valuable).
| Feature | Description |
|---|---|
| Originality | The idea is new and unique |
| Flexibility | Ability to see things from different perspectives |
| Fluency | Generating a large number of ideas |
| Elaboration | Developing and refining ideas in detail |
Convergent vs. Divergent Thinking
| Type | Description |
|---|---|
| Convergent thinking | Narrowing down to find the single best answer (e.g., solving a maths problem) |
| Divergent thinking | Generating multiple possible solutions (key to creativity) |
7.7.2 Process and Strategies of Creative Thinking
Wallas’s Four-Stage Model of Creativity:
| Stage | Description |
|---|---|
| Preparation | Gathering information, studying the problem intensively |
| Incubation | Stepping away from the problem; unconscious processing continues |
| Illumination | The “aha!” moment — the creative solution suddenly appears |
| Verification | Testing and refining the solution |
Strategies to enhance creativity:
- Brainstorming — generating as many ideas as possible without judging them
- Lateral thinking (Edward de Bono) — approaching problems from unconventional angles
- Mind mapping — visually organising ideas around a central concept
- Tolerance for ambiguity — being comfortable with uncertainty
7.8 Thought and Language
Thought and language are deeply interconnected:
- Language influences thought (Sapir-Whorf hypothesis / linguistic relativity) — the language we speak shapes how we think and perceive the world
- Thought influences language — we choose words to express our ideas
- Language extends thought — complex ideas can be communicated and refined through language
Sapir-Whorf Hypothesis: The strong version (linguistic determinism) says language determines thought. The weaker version (linguistic relativity) says language influences thought. Most psychologists support the weaker version.
7.9 Development of Language and Language Use
| Stage | Age | Key Features |
|---|---|---|
| Cooing | 2–4 months | Vowel-like sounds |
| Babbling | 6–9 months | Consonant-vowel combinations (“ba-ba”, “da-da”) |
| First words | 10–13 months | Single words (holophrastic speech: one word = a sentence) |
| Two-word stage | 18–24 months | Telegraphic speech (“want milk”, “daddy come”) |
| Sentences | 2–3 years | More complex sentences; rapid vocabulary growth |
| Grammar mastery | 4–6 years | Most grammatical rules learned; still make errors (“goed” instead of “went”) |
Noam Chomsky proposed that humans are born with an innate Language Acquisition Device (LAD) — a biological capacity for learning language.

Practice Questions
Section A – Multiple Choice Questions (1 mark each)
Q1. The inability to see an object as having a function other than its usual one is called:
(a) Mental set (b) Functional fixedness (c) Confirmation bias (d) Anchoring
Answer
(b) Functional fixedness
Functional fixedness is the tendency to think of objects only in terms of their typical functions, which can hinder creative problem solving.
Q2. Divergent thinking is most closely associated with:
(a) Mathematical calculation (b) Convergent thinking (c) Creativity (d) Deductive reasoning
Answer
(c) Creativity
Divergent thinking involves generating multiple possible solutions to a problem and is the key cognitive process underlying creativity.
Q3. “All birds can fly. A penguin is a bird. Therefore, a penguin can fly.” This is an example of:
(a) Inductive reasoning (b) Deductive reasoning (c) Creative thinking (d) Heuristic
Answer
(b) Deductive reasoning
This follows the deductive structure (general premise → specific conclusion). Note: the conclusion is logically valid (it follows from the premises) but factually incorrect because the premise “all birds can fly” is false.
Q4. Wallas’s model of creativity includes all of the following stages EXCEPT:
(a) Preparation (b) Incubation (c) Accommodation (d) Verification
Answer
(c) Accommodation
Wallas’s model includes: Preparation, Incubation, Illumination, and Verification. Accommodation is a concept from Piaget’s cognitive development theory, not from the creativity model.
Section B – Short Answer Questions (2 marks each)
Q5. Differentiate between deductive and inductive reasoning with examples.
Answer
| Feature | Deductive Reasoning | Inductive Reasoning |
|---|---|---|
| Direction | General → Specific | Specific → General |
| Certainty | Conclusions are certain (if premises are true) | Conclusions are probable but not guaranteed |
| Example | All humans are mortal. Socrates is human. ∴ Socrates is mortal. | I’ve seen 100 crows and all are black. ∴ All crows are black. |
Q6. What is the Sapir-Whorf hypothesis? Briefly explain its two versions.
Answer
The Sapir-Whorf hypothesis (also called the linguistic relativity hypothesis) proposes that the language we speak influences or determines how we think and perceive the world.
Two versions:
-
Strong version (Linguistic Determinism): Language determines thought. Without the word for a concept, the concept cannot be thought. (Largely rejected by modern psychology.)
-
Weak version (Linguistic Relativity): Language influences thought and perception without fully determining it. E.g., cultures with many words for snow may perceive subtle differences more easily. (Widely supported.)
Section C – Long Answer Questions (5 marks each)
Q7. Discuss the nature and process of creative thinking. How can creativity be enhanced?
Answer
Creativity is the ability to produce ideas, solutions, or products that are both novel (original) and useful (appropriate, meaningful).
Characteristics of Creative Thinking:
- Originality — produces unique ideas
- Fluency — generates many ideas
- Flexibility — shifts between different approaches
- Elaboration — develops ideas in rich detail
Divergent vs. Convergent Thinking:
- Divergent thinking generates multiple possible solutions — central to creativity
- Convergent thinking narrows options to find the best single answer — central to analytical reasoning
Process of Creative Thinking (Wallas’s Model):
- Preparation: Intensive study and gathering of information about the problem
- Incubation: The problem is set aside; unconscious processing occurs without deliberate effort
- Illumination: A sudden flash of insight — the creative solution appears
- Verification: The solution is tested, refined, and evaluated
Enhancing Creativity:
- Brainstorming — generating ideas freely without criticism
- Encouraging curiosity — exploring diverse interests and perspectives
- Tolerating ambiguity — being comfortable with uncertainty and open-ended problems
- Creating a supportive environment — schools and workplaces that value experimentation and do not punish failure
- Lateral thinking (de Bono) — deliberately approaching problems from unconventional directions
- Exposure to diverse experiences — travel, reading, meeting people from different backgrounds
Section D – Competency-Based Questions (CBSE Pattern)
Q8. (Case Study)
A group of students is given the following problem:
“You have two candles, a box of thumbtacks, and a book of matches. How can you mount a lit candle on a wall so that the wax doesn’t drip on the floor?”
Most students try to melt wax to stick the candle to the wall, or tack the candle directly. Only one student thinks of emptying the thumbtack box, tacking the box to the wall, and placing the candle inside the box.
(i) What obstacle to problem solving did most students experience?
(ii) What type of thinking did the successful student demonstrate?
(iii) Name the specific type of problem-solving approach the successful student used.
(iv) Suggest how teachers can help students overcome this obstacle.
Answer
(i) Most students experienced functional fixedness — they saw the thumbtack box only as a container for thumbtacks, not as a potential shelf or platform for the candle.
(ii) The successful student demonstrated divergent thinking — the ability to see multiple possible uses for the same object and think beyond conventional functions.
(iii) The successful student used insight (the “aha!” moment) — a sudden restructuring of the problem that led to a novel solution.
(iv) Teachers can help students overcome functional fixedness by:
- Encouraging brainstorming without immediate judgment
- Presenting objects in non-traditional contexts (e.g., “How many uses can you think of for a brick?”)
- Teaching lateral thinking techniques that encourage looking at problems from different angles
- Creating a classroom culture where mistakes and unusual ideas are valued, not punished
Q9. (Application-Based)
Consider the following two statements:
Statement 1: “90% of patients survive this surgery.”
Statement 2: “10% of patients die during this surgery.”
Both statements convey the same information, yet people tend to view the surgery more favourably when presented with Statement 1.
(i) What psychological phenomenon does this illustrate?
(ii) How does this phenomenon affect decision-making?
(iii) Give one more everyday example of this phenomenon.
Answer
(i) This illustrates the framing effect — the way information is presented (framed) significantly influences people’s decisions and judgements, even when the underlying facts are identical.
(ii) The framing effect affects decision-making by causing people to make different choices based on whether the same information is presented in a positive frame (emphasising gains — “90% survive”) or a negative frame (emphasising losses — “10% die”). People tend to be:
- Risk-averse when options are framed as gains (they prefer the safe option)
- Risk-seeking when options are framed as losses (they take bigger risks to avoid losses)
(iii) Everyday example: A food product labelled “95% fat-free” is perceived more favourably than the same product labelled “contains 5% fat”, even though both convey identical information. Advertisers deliberately use positive framing to make products seem healthier or more appealing.
