Educational psychology and psychology are two different disciplines, and their research contents, methods and objectives are somewhat different.

First of all, educational psychology mainly focuses on the learning and teaching process in the educational environment. It studies the influence of students' learning style, learning motivation, learning strategies and teachers' teaching strategies on students' academic performance. The goal of educational psychology is to help educators understand students' psychological characteristics, optimize teaching methods and improve students' learning effect.

On the other hand, psychology is a broader discipline, which studies human psychological processes and behaviors. Psychology includes many branches, such as clinical psychology, social psychology and cognitive psychology. Clinical psychology mainly focuses on the diagnosis and treatment of mental health problems and psychological disorders; Social psychology studies interpersonal relationship, group behavior and social influence. Cognitive psychology studies psychological processes such as thinking, memory, learning and decision-making.

Secondly, educational psychology and psychology have different research methods. Educational psychology usually adopts the methods of experimental research and investigation, verifying hypotheses through designing and implementing teaching experiments, or collecting data through questionnaire survey and observation. Psychology, on the other hand, is more diversified and can be studied through experiments, investigations, observations and case studies.

In addition, educational psychology and psychology also have differences in research objects. Educational psychology mainly studies the psychological characteristics and behaviors of students and teachers in the educational environment, while psychology has a wider scope and can study the psychological processes and behaviors of different ages, groups and situations.

To sum up, educational psychology and psychology are two different disciplines, and there are certain differences in research content, research methods and research objectives. Educational psychology mainly studies the learning and teaching process in the educational environment, while psychology has a wider scope and studies people's psychological process and behavior.
