Psychology Full Course –Volume 04: Intelligence
Intelligence
Intelligence has been defined in many ways: the capacity for abstraction, logic, understanding, self-awareness, learning, emotional knowledge, reasoning, planning, creativity, critical thinking, and problem-solving. It can be described as the ability to perceive or infer information and to retain it as knowledge to be applied to adaptive behaviors within an environment or context.
Most psychologists believe that intelligence can be divided into various domains or competencies.
Intelligence has been long-studied in humans, and across numerous disciplines. It has also been observed in the cognition of non-human animals. Some researchers have suggested that plants exhibit forms of intelligence, though this remains controversial.

How to Use this Handbook
This handbook is organised as short chapters, each built around the Videos from the corresponding playlist published on the YouTube Channel @FiveMinuteLearnings. To get the most out of it:
Start with the AT A GLANCE box at the beginning of every chapter — it gives you the key idea, the psychologist behind it, the theory category, and a real-world application in a single glance.
Read the chapter itself — this is the original script from the video, lightly edited for readability, so the voice and examples remain exactly as taught.
Review the KEY TAKEAWAYS at the end of each chapter for quick revision — ideal before an exam or interview.
Scan the QR code (or tap the link) in any chapter to watch the full video lesson on YouTube.
If you are preparing for exams such as UPSC or undergraduate psychology assessments, the AT A GLANCE and KEY TAKEAWAYS sections together work well as a rapid revision guide across all chapters.
