Psychology

Psychology is the academic and scientific study of the mind, its processes, and behaviors. It encompasses a broad range of topics including thought, feeling, and action in both humans and, at times, nonhuman animals. As a discipline, psychology straddles the boundary between biology and social sciences, drawing methods and insights from both areas as well as from fields such as medicine, ethology, computer science, and linguistics.

A professional in this field, known as a psychologist, may specialize as a social, behavioural, or cognitive scientist. Psychologists aim to understand the role of mental functions in individual and social behavior while exploring the physiological and neurobiological processes that underpin cognitive functions and behaviors.

Branches

Psychology is divided into various branches, each focused on different aspects of human thought, behavior, and development:

• Abnormal psychology examines the distinctions between psychological health and illness.
• Clinical psychology is dedicated to understanding, preventing, and relieving psychologically based distress or dysfunction.
• Cognitive psychology explores mental processes such as perception, memory, thought, and problem-solving.
• Cross-cultural psychology investigates how cultural contexts influence human behavior and mental processes.
• Developmental psychology studies the growth and changes that occur throughout a person’s life.
• Educational psychology or school psychology assesses and intervenes in children's learning and socialization.
• Evolutionary psychology considers how evolutionary principles inform human thought and behavior.
• Neuropsychology examines the structure and function of the brain as they relate to specific psychological processes and behaviors.
• The study of Motivation looks at the driving forces behind human actions.
• Perceptual psychology delves into how people perceive their environment and make sense of sensory information.
• Social psychology explores how individuals influence and are influenced by others within a societal context.

Methods

Scientific approaches

Psychology employs scientific methods to formulate and test hypotheses related to mental processes and behavior. This includes controlled laboratory experiments, surveys, longitudinal studies, and case studies, among others. Due to ethical considerations, certain types of experiments may be restricted, leading researchers to employ observational studies or animal models to gain insights.

A hallmark of scientific psychology is the principle of falsifiability—proposing hypotheses that can be empirically tested and potentially disproven. This approach underpins the robust, empirical investigation of psychological phenomena.

Symbolic and subjective approaches

In addition to scientific methods, psychology also encompasses symbolic and subjective approaches such as psychodynamic psychology and depth psychology. These perspectives often focus on uncovering the unconscious motivations behind behaviors and utilize techniques like dream analysis. Humanistic psychology and existential psychology prioritize the understanding of individual experiences and personal meaning over the identification of general laws of behavior.

Psychologists

To practice as a psychologist requires extensive education, typically beginning with a bachelor's degree followed by postgraduate studies. A Master's degree (MSc or MA) may qualify an individual to work in areas such as school psychology, while a doctoral degree (PhD, DPhil, or PsyD) is necessary for clinical practice and academic research. Licensure is a further requirement for clinical practice in many jurisdictions.

While psychologists and psychiatrists both focus on mental health, psychiatrists are medical doctors (MD) who can prescribe medication, often working alongside psychologists in treatment planning.
