Long-Term Memory: Stores knowledge for days, years, or life

How Memories Are Formed

Information enters sensory memory
Attention moves it into short-term memory
Repetition and meaning transfer it into long-term memory

Why We Forget

Lack of attention
Weak encoding
Interference from similar memories
Brain overload

Forgetting is normal—it helps the brain prioritize important information.

3. How the Brain Thinks and Solves Problems

Thinking is the combination of reasoning, decision-making, problem-solving, and creativity. Cognitive psychology reveals that our brains use both automatic and controlled processes.

Automatic Thinking

Fast, instinctive
Requires little effort
Example: Recognizing a familiar face

Controlled Thinking

Slow and deliberate
Used for complex decisions
Example: Planning a project or solving math problems

Common Thinking Patterns

Heuristics: Mental shortcuts that speed up decision-making
Biases: Systematic errors in thinking
Creative Processes: Combining ideas in new and useful ways

These insights explain why we sometimes make irrational choices or find sudden inspiration.

4. The Role of Attention in Cognitive Processing

Attention acts as a filter that determines what enters our conscious mind. Without attention, learning and memory become nearly impossible.

Types of Attention

Selective attention: Focusing on one thing despite distractions
Sustained attention: Concentrating for long periods
