What is Psychological Science?

Psychological science is the systematic study of behavior and mental processes.

What are the research methods in psychology?

Research is the cornerstone of scientific psychology. This manual explains the main methods used to study behavior: controlled experiments, correlational studies, naturalistic observations, surveys, and case studies. It also addresses the importance of ethics in research, experimental design, sample selection, and data analysis. The reader will learn to interpret statistical results and evaluate the validity of findings, essential skills for any psychology student. Furthermore, common biases and how to avoid them are highlighted, fostering a critical and reflective attitude.

What are the main areas of psychology?
