Subfields of Psychology


Sub-fields of Psychology

     
If we are going to give a complete introduction to psychology, it will not be easier. There is a reason for it to be difficult. That is the content of psychology is bigger than any subject in the world. So today psychologists have had to define psychology in many various ways because in the today world, people are dealing with psychology in many ways. But in every definition on psychology has a general factor. It is none other than this every definition is directly combined with “the mental process and behavior” of any beings which are human and nonhuman (animal or paranormal).

These various types of definitions on psychology are not accidental because they have originated with needs of people which act in different types of roles. In fact, where is people deal with, there is psychology. That’s why there is a great diversity in psychology. So we can identify a lot of subfields within psychology. A subfield of psychology means an area which having used psychological knowledge people deal with. 


Types of Psychology     


In Greek era, psychology was a study of soul and later it became a study of mind. After psychology was taken out from philosophy, it became an independent science. Today psychology touches a large number of other subjects including Philosophy, Anthropology, Sociology, Biology, Engineering, Technology, Mathematics, Statistics, Legal science, Strategy, Aesthetics, Logic, Literature, Education, Religion and more and more.

So according to the way people deal with this subject today, Psychology can be roughly divided into two major sections. One is research which seeks to increase our knowledge base. Another is practice which our knowledge is applied to solving problems in the real world. The study and practice of psychology encompass a vast range of subfields and specialty areas as a result of development happened during cause of a long time. Because human behavior is so varied, the number of subfields in psychology is constantly growing and evolving. Most of these subfields have been firmly established as areas of interest.


The use of knowing about sub-fields of psychology


 There are several sub-fields of psychology to consider when studying psychology. So knowing this will help you to understand the importance of studying psychology. Most of all, it's important to know where your interests lie in the broad area of psychology. So you can make an informed decision about what you want to study in psychology and how you can employ your skills in psychology. As well as, it will ensure that you'll be on the right path toward a successful psychology career.  

The fields of psychology encompass both research, which we learn fundamental things about human and animal behavior, and practice, which that knowledge is applied to solve problems and support human development. In each of the sub-fields there are psychologists who work primarily as researchers, others who work primarily as practitioners and many of them do both (scientist-practitioners). This will help you to understand the variety of careers also in psychology.  The following are brief descriptions of some of the subfields in psychology.

This will help you to understand the variety of careers also in psychology.  The following are brief descriptions of some of the subfields in psychology.


01.  Abnormal Psychology

    
Abnormal psychology is the study of abnormal behavior of individuals including the factors, situations, and conditions that cause mental disorders and emotional problems and how they may be best treated. This knowledge is applied in clinical psychology to treat patients with psychological disorders.
     
Abnormal psychologists can help people to live better lives. Careers in abnormal psychology encompass a wide range of interests and services. Most treating psychologists, including counselors, psychotherapists, clinical social workers, and clinical psychologists, are specialists in abnormal psychology.


02.  Biological Psychology


Biology is defined as “the study of life” (from the Greek bios meaning life and logos meaning study). A biological perspective is relevant to the study of psychology in three ways. Comparative method: different species of animal can be studied and compared. This can help in the search to understand human behavior. Physiology: how the nervous system and hormones work, how the brain functions, how changes in structure and/or function can affect behavior. Investigation of inheritance: what an animal inherits from its parents, mechanisms of inheritance (genetics).

Biological psychology is the scientific study of the biological side of behavior and mental states. Seeing all behavior as intertwined with the nervous system, biological psychologists feel it is sensible to study how the brain functions in order to understand behavior. This is the approach taken in behavioral neuroscience, cognitive neuroscience, and neuropsychology. 

Bio-psychologists employ in various areas to include cognitive neuroscience, psychopharmacology, neuropsychology, behavioral genetics and comparative psychology.  Each area uses the combination of biology and psychology in different ways.


03.  Child Psychology


Child psychology is one of the branches of psychology focuses on the mind and behavior of children from prenatal development through adolescence. Child psychology deals not only with how children grow physically, but with their mental, emotional and social development as well. Today, psychologists recognize that child psychology is unique and complex.

The different contexts of child psychology are Social Context, Cultural Context and Socioeconomic Context. Some of main subjects of child psychology are Genetics, Environmental Influences, Prenatal Development, Social Growth, Personality Development, Language, Gender Roles, Cognitive Development, Sexual development.    

Child psychologists work in different ways. 

·         Abnormal child psychologist: Works with children suffering from psychological disorders including anxiety, mood and personality disorders. 

·         Adolescent psychologist: Works with adolescent clients between the ages of 12 and 18 who suffer from psychological illness or distress including eating disorders, depression or anxiety. 

·         Developmental psychologist: May study childhood development. 

·         School psychologist: Works within the educational system to help children with emotional, social and academic issues. 

·         Educational psychologist: Involves the study of how people learn, including topics such as student outcomes, 
      the instructional process, individual differences in learning, gifted learners and learning disabilities.


04.  Clinical Psychology


Clinical psychology is the largest specialty area in psychology. This is the branch of psychology paid attention to the treatment of mental illness, abnormal behavior and psychiatric problems. Wilhelm Wundt defined clinical psychology as "the study of individuals, by observation or experimentation, with the intention of promoting change." Today, clinical psychology is one of the most popular subfields within psychology. 


Some of the major theoretical perspectives within clinical psychology include:

·         Psychodynamic Approach: This comes from psychoanalyst Sigmund Freud, who believed that the unconscious mind played an important role in our behavior. Psychologists who utilize this perspective may use techniques such as free association to investigate a client's underlying, unconscious motivations.

·         Cognitive Behavioral Perspective: by using this perspective, Clinical psychologists look at how a client's feelings, behaviors and thoughts interact. Cognitive-behavioral therapy often focuses on changing thoughts and behaviors that contribute to psychological distress.

·         Humanistic Perspective: This perspective looks at the client more holistically and is focused on such things as 
      self-actualization and helping people realize their full potential.

Clinical psychologists assess and treat mental, emotional, and behavioral disorders. Some clinical psychologists treat specific problems exclusively, such as phobias or clinical depression. Others focus on specific populations: youngsters, ethnic minority groups, gays and lesbians, and the elderly, for instance. They also consult with physicians on physical problems that have underlying psychological causes.


05.  Cognitive Psychology

    
Cognitive psychology studies mental processes including how people think, perceive, remember and learn. As part of the larger field of cognitive science, this branch of psychology is related to other disciplines including neuroscience, philosophy and linguistics. This includes: Memory, Problem-Solving, Perception, Language, information Processing. Cognitive psychology is unlike behaviorism, which focuses only on observable behaviors, cognitive psychology is concerned with internal mental states. Cognitive psychology is unlike psychoanalysis, which relies heavily on subjective perceptions; cognitive psychology uses scientific research methods to study mental processes.

Cognitive psychology is investigated in several ways:

·           Experimental cognitive psychology- this is the heart of all cognitive psychology and it uses carefully controlled experiments. Experimental approach is influential on all of psychology like clinical, social, developmental etc.

·         Cognitive neuropsychology- this is investigation of cognitive performance in brain damaged or brain diseased patients.  

·         Computational cognitive science- this involves computer programming to model or mimic some kind of cognitive function. Artificial Intelligence involves computer programming to construct intelligent outcomes, not necessarily resembling human processes.                


·         Cognitive neuroscience- this is the study of mental processes in the functioning brain to understand how the brain works (or functions cognitively). Cognitive neuroscientists often use neuroimaging tools, which can help them to observe which areas of the brain are active during a particular task. 

Cognitive psychologists also study reasoning, judgment, and decision making. Cognitive and perceptual psychologists frequently collaborate with behavioral neuroscientists to understand the biological bases of perception or cognition or with researchers in other areas of psychology to better understand the cognitive biases in the thinking of people with depression.

Cognitive psychologists work in a number of areas. Many cognitive psychologists conduct applied research or basic research on the human thought process. Cognitive psychologists often work at colleges and universities, government agencies, corporate businesses and in private consulting. Common careers titles include university instructor, human factors consultant, industrial-organizational manager and usability specialist.

The comparative method can also be used to compare modern species of animals to ancient species. Major Topics in Comparative Psychology are Evolution, Heredity, Adaptation and learning, Mating and parenting behaviors, Primates.   
 
The study of animal behavior can lead to a deeper and broader understanding of human psychology. Research on animal behavior has led to numerous discoveries about human behavior, such as Ivan Pavlov's research on classical conditioning or Harry Harlow's work with rhesus monkeys. Students of biological sciences and social sciences can benefit from studying comparative psychology.


07.  Community Psychology


  
Community psychology is a special area concerned with how individuals relate to society.  How do people become more active contributors in their communities? How do community issues impact the health and illness of individuals? These are both major topics of community psychology.

Many counseling psychologists provide psychotherapy services, but other career paths are also available. Research, teaching and vocational counseling are just a few of the possible alternatives to psychotherapy.

  9. Excellent post.

    One thing I have noticed about certain sites is that, even though they have tons of content, the site looks great and the headlines are eye catching is that the material is simply filler. It’s downright unreadable. You can forget it 6 seconds after you read it. Not the case with your post though, really enjoyed it reading it and it held my attention all the way through!
