Thinking

Thinking is a higher mental process through which we manipulate and analyze information. Its key features are:

• Internal Process: It happens inside the mind and is inferred from behaviour.
• Symbolic: It involves mental representations (images, concepts, symbols) rather than physical objects.
• Goal-Directed: It is usually directed towards solving a problem or reaching a conclusion.

A Concept is a mental category for grouping objects, events, or ideas that share common characteristics (e.g., the concept of “Fruit” includes apple, banana, mango).
Role in Thinking:

• Organization: They help us organize our knowledge efficiently, reducing cognitive load.
• Prediction: Once we categorize something (e.g., identifying an animal as a “Dog”), we know what to expect (it barks, has 4 legs).
• Speed: Concepts allow for quicker processing of new information without analyzing every detail.

• Mental Set: The tendency to use old solutions that worked in the past, even if they don’t work now (Rigidity).
• Functional Fixedness: The inability to see a new use for an object (e.g., failing to see that a coin can be used as a screwdriver).
• Lack of Motivation: Giving up too easily when faced with difficulty.

Reasoning is realistic thinking that draws conclusions from facts.

• Deductive Reasoning: Going from general principles to specific cases. (e.g., “All birds lay eggs” $\rightarrow$ “Penguin is a bird” $\rightarrow$ “Penguin lays eggs”).
• Inductive Reasoning: Going from specific observations to general truths. (e.g., “This metal expands on heating”, “That metal expands on heating” $\rightarrow$ “All metals expand on heating”).

It helps us evaluate solutions logically rather than guessing.

Yes, they are deeply interrelated.

• Judgment: The process of forming opinions, reaching conclusions, or evaluating events (e.g., “Is this car reliable?”).
• Decision Making: The process of making a choice between alternatives based on judgments (e.g., “I will buy this car”).
• Relation: You cannot make a good decision without first exercising judgment to evaluate the options.

[Image of divergent vs convergent thinking] Divergent Thinking is the ability to generate multiple unique solutions to a single problem. It is the core of creativity because:

• Fluency: It produces many ideas.
• Flexibility: It produces different types of ideas.
• Originality: It produces novel/unusual ideas.
• Unlike Convergent Thinking (which looks for one correct answer), divergent thinking opens up possibilities essential for innovation.

• Brainstorming: Generating ideas freely without criticism (Osborn).
• Avoiding Mental Sets: Consciously trying to look at problems from new angles.
• Visualizing: Using mental imagery to construct new scenarios.
• Feedback: Engaging with others to refine ideas.

This is a debated topic:

• Whorfian Hypothesis (Linguistic Relativity): Argues that language determines thought (e.g., if you don’t have a word for a color, you can’t perceive it).
• Piaget’s View: Thought precedes language. Children form concepts (internal) before they learn words for them.
• Conclusion: Thinking can occur without language (e.g., visual thinking, spatial reasoning), but language greatly refines and expands the complexity of thought.

There are two main theories:

• Behaviorist View (Skinner): Language is learned through conditioning, imitation, and reinforcement (nurture).
• Nativist View (Chomsky): Humans are born with an innate Language Acquisition Device (LAD) and a Universal Grammar that allows them to learn language rapidly (nature).
• Critical Period: Language is best acquired in childhood; it becomes difficult after puberty.

(Guidance for Observation)
Typical Milestones you will record:

• 1 Year Old: Holophrases. Using single words to convey whole sentences (e.g., “Milk” meaning “I want milk”).
• 2 Years Old: Telegraphic Speech. Two-word sentences (e.g., “Daddy go”, “Big dog”). Vocabulary explosion occurs here.
• 3 Years Old: Complex Sentences. Using grammar, plurals, and tenses (e.g., “I played with the ball”).

Note: Language development follows a universal sequence but the rate varies per child.
