Introduction to Psychology Notes PDF

What is Psychology? Psychology is the science of mind and behavior. Its immediate goal is to understand behavior and mental processes by researching and establishing both general principles and specific cases.

For many practitioners, one goal of applied psychology is to benefit society. In this field, a professional practitioner or researcher is called a psychologist, and can be classified as a social scientist, behavioral scientist or cognitive scientist. 

Psychologists attempt to understand the role of mental functions in individuals and social behavior, while also exploring the physiological and neuro-biological processes that underlie certain functions and behaviors. 

Psychologists explore such concepts as perception, cognition, attention, emotion, phenomenology, motivation, brain functioning, personality, behavior, and interpersonal relationships.

Some, especially depth psychologists, also consider the unconscious mind; Psychologists employ empirical methods to infer causal and Correlational relationships between psycho-social variables.

In addition, or in opposition, to employing empirical and deductive methods, some especially clinical and counseling psychologists, at times rely upon symbolic interpretation and other inductive techniques.

Psychologists use experiments, surveys, and brain studies to explore human functioning. The term “psychological psychology” may also appear in online searches when users want deeper information about psychological theories or mental health topics. 

Understanding the scientific foundation of psychology helps clarify this confusion and shows that psychology already includes both mental and behavioral research.
