Introduction to Psychology and Research Methods

TL;DR

Psychology is the scientific study of mind and behavior, using systematic methods to understand why we think, feel, and act the way we do. Research methods are crucial for gathering reliable evidence, ensuring our understanding isn't based on assumptions or personal opinions. You'll learn about different research designs and ethical considerations that guide psychological inquiry.

There are several ways psychologists collect data, each with strengths and weaknesses:

• Descriptive Research: Aims to observe and describe behavior without manipulating variables.
  • Naturalistic Observation: Watching behavior in its natural environment (e.g., observing playground interactions).
  • Case Studies: In-depth st
