Understanding Cognition: Thinking, Reasoning, and Critical Analysis

1. Meaning of Thinking (Cognition)

Thinking, or cognition, is a mental process involving information processing, understanding, organizing ideas, decision-making, and problem-solving. The term originates from the Latin word meaning “to know.”

Definitions

• Ross: Thinking is a mental activity in its cognitive aspect.
• Garrett: Thinking is an implicit behavior using symbols. It encompasses memory, reasoning, decision-making, and problem-solving.

2. Mental Images and Concepts

Mental images are picture-like representations formed in the mind that assist in imagination and planning. Concepts are general ideas representing a class or category, which help reduce mental effort.

Example: The concept “fruit” includes items such as apples, mangoes, and bananas.

3. Types of Thinking

• Perceptual or Concrete Thinking: Based on direct sensory experience, such as seeing or hearing.
• Conceptual or Abstract Thinking: Uses ideas, concepts, and symbols for complex problem-solving.
• Reflective Thinking: Logical and systematic thinking utilizing past experiences.
• Non-directed or Associative Thinking: Goal-less and free-flowing, often observed in daydreaming.
• Creative Thinking: Produces new and original ideas.
• Critical Thinking: Logical and rational thinking that evaluates information.

Important Exam Note: Critical thinking is considered the most essential type of thinking.

4. Critical Thinking

Critical thinking is the ability to think clearly, analyze logically, and make justified decisions.

Characteristics

• Questions assumptions
• Analyzes arguments
• Uses logic and evidence
• Involves self-reflection
• Improves decision-making

Skills

• Understanding relationships
• Evaluating arguments
• Identifying errors
• Logical decision-making

Key Insight: Critical thinking transforms an individual into an active learner.

5. Reasoning and Prediction

Reasoning is the logical process of drawing conclusions from assumptions. Logic studies the structure of arguments rather than their content.

Note: Logic concerns itself specifically with the structure of arguments.

6. Memory and Critical Thinking

Memory is the ability to encode, store, and retrieve information.

Processes of Memory

1. Encoding
2. Storage
3. Retrieval

Types of Memory

• Sensory memory: Lasts a few seconds.
• Short-term memory: Lasts 20–30 seconds.
• Long-term memory: Long duration.

Critical thinking depends primarily on long-term memory, as past experiences inform present decisions. Key Insight: Long-term memory acts as the foundation of experience in critical thinking.

7. Emotion and Critical Thinking

Emotion involves feelings, bodily reactions, and behavior. Paul Ekman identified six basic emotions: happiness, sadness, fear, anger, disgust, and surprise. Emotions significantly influence thinking and decision-making. Emotional intelligence helps manage these feelings, and as Antonio Damasio stated, emotions are central to rational thought.
