Psychology is the scientific study of mental processes and behavior, using research methods to understand how people think, feel and interact. This foundation opens doors to careers in mental health such as clinical psychologist or counselor; in education as school psychologist or academic advisor; in business as organizational consultant or human resources specialist, and in research roles such as neuroscientist or market researcher, where skills in assessment, experimentation and data analysis inform programs and policies. Ultimately, applying psychological insights fosters personal growth, strengthens relationships and improves quality of life.
