Introduction to Psychology

In a nutshell, we can say that the scientific study of mind and behavior is called the Psychology. The base form of word psychology is basically the combination of two Greek words as follows: –

  • “Psyche” (life)
  • “Logos” (explanation)

Hence, we can simple understand its meaning as the explanation of life, a study or knowledge which deals with the explanation of life is called Psychology. It deals with every area of life i.e. the students, the media, the society itself, even it has become a popular part of everyday life.

On television, we see many psychologists who are continuously providing personal advice to large number of patients suffering from personal and family difficulties. For understanding of impact of psychology, we can see many movies which actually psychological thrillers as case studies.

During prime time, viewers see many action drama or serials related to crime where forensic psychologists are busy in knowing the cause of crime by providing tangible evidences to the investigators. They are trying their best to solve the complexity of crime.

Even viewers are sharing their experiences as they might have visited psychologists or meet school counselor, or consulted family therapists etc. It is a habit of people to show their interest in solution of any domestic problem especially during marriage functions, or religious gatherings.

It is just because we are exposed to the work of psychologist in our daily lives frequently, and we are very sure what is the role of a psychologist and what benefits do people are getting from him. Students are studying psychology as a subject in their BS, Masters and PhD programs enthusiastically.

Mainly they are more interested in social psychology and clinical psychology. Researchers have also introduced many more disciplines of psychology like developmental psychology, environmental psychology, and psychology of religion etc.

Role of Psychologists

After life experiences, we can say that psychologists are playing their role positively in the betterment of patients’ lives. Undoubtedly I can say that their role is exemplary.

No only they provide positive counseling and therapy to people in distress but also they do significant work in forensic laboratories which are very essential for provisioning of evidences. These evidences are then produced to court of law to maintain justice in the society.

Even then we are not sure how many other fields of life where psychologists are working and playing their role, probably we are not aware of it. There are some research laboratories in developed countries, there are research and teaching hospitals and some other departments are there where behaviors of humans and animals are being studied. 

Contemporary Psychology

In contemporary psychology, it can be surprising for you that psychologists are studying and working on very diverse topics like anxiety in children, the possible meanings of un-usual dreams, the effects of drug on thinking capability, how birds of different breed recognize each other while sitting on a same tree.

Researchers are also working on the topic that how people of different communities can negotiate and engage in positive solutions of their problems. Psychologists are also working for the people of terrorist hit countries so that the mental stress of target population can be minimized.

Advancements in Psychology

Day by day advancement in the field of psychology is happening. Psychologists are working in the following areas as well:

  • the impact of alcohol
  • Causes of excessive drug addiction
  • Reasons of memory loss
  • Sudden rise and fall in emotions
  • Acceptance and rejection in love
  • Why do people become aggressive without any apparent reason
  • How can similarities among cultures be noticed etc

As world is now focusing on financial matters a lot, hence the psychologists are working on this aspect of humans.

They use variety of methodologies, observational techniques, conducting interviews of businessman to study the rise or fall of certain business.

Advancements have led to new treatments for mental health disorders, improved understanding of human behavior, and new areas of research and exploration.

Use of Empirical Methods in Psychology

Almost all scientists, whether they are physicists, chemists, biologists, sociologists, or psychologists, use empirical methods to study the topics that interest them. Empirical methods include the processes of collecting and organizing data and drawing conclusions about those data.

The empirical methods used by scientists have developed over many years and provide a basis for collecting, analyzing, and interpreting data within a common framework in which information can be shared. We can label the scientific method as the set of assumptions, rules, and procedures that scientists use to conduct empirical research.

introduction to psychology detail

Although scientific research is an important method of studying human behavior, not all questions can be answered using scientific approaches. Scientists therefore draw a distinction between values and facts.

Values are personal statements such as “Abortion should not be permitted in this country,” “I will go to heaven when I die,” or “It is important to study psychology.”

Facts are objective statements determined to be accurate through empirical study. Statements that cannot be objectively measured or objectively determined to be true or false are not within the domain of scientific inquiry.

The Challenges of Studying Psychology

It is very difficult to restrict psychologist with less experience from false explanation of behavior. There are certain aspects of biological psychology as well. Psychologist cannot focus all the time the conscious experiences of humans.

He may not allow to ask questions related to gender from his patient. The deterioration in health can expand consciousness of patient in negative way. Psychologist may suggest medication, electron-convulsive, shock therapy, and psycho-surgery of patient.

Understanding and attempting to alleviate the costs of psychological disorders such as depression is not easy, because psychological experiences are extremely complex.

A major goal of psychology is to predict behavior by understanding its causes after detailed analysis of the concept nature vs nurture. Making predictions is difficult in part because people vary and respond differently in different situations. Individual differences are the variations among people on physical or psychological dimensions.

For instance, although many people experience at least some symptoms of depression at some times in their lives, the experience varies dramatically among people.

chanllenges of studying psychology

Some people experience major negative events, such as severe physical injuries or the loss of significant others, without experiencing much depression, whereas other people experience severe depression for no apparent reason.

Other important individual differences that has been discussed on other articles available on our website include differences in extraversion, intelligence, self-esteem, anxiety, aggression, and conformity. The predictions made by psychologists (and most other scientists) are only probabilistic.

We can say, for instance, that people who score higher on an intelligence test will, on average, do better than people who score lower on the same test, but we cannot make very accurate predictions about exactly how any one person will perform.

Another difficulty in studying psychology is that much human behavior is caused by factors that are outside our conscious awareness, making it impossible for us, as individuals, to really understand them.

The role of unconscious processes was emphasized in the theorizing of the Austrian neurologist Sigmund Freud, who argued that many psychological disorders were caused by memories that we have repressed and thus remain outside our consciousness. Unconscious processes will be an important part of our study of psychology.

Comparison of Various School of Thoughts in Psychology

Some prominent school of thoughts are appended below. As a reader you should identify the concept and prepare a single line statement regarding each of the school.

School of ThoughtsNomenclature
StructuralismUses the method of introspection to identify the basic elements or “structures” of psychological experience
FunctionalismAttempts to understand why animals and humans have developed the particular psychological aspects that they currently possess
PsychodynamicFocuses on the role of our unconscious thoughts, feelings, and memories and our early childhood experiences in determining behavior
BehaviourismBehaviour also involves evolutionary perspective of psychology. Researches have revealed that psychology is a science of behaviour and deals with the mind and brain of person. The study of behaviour and mental processes is the central core area of focus in psychology. Based on the premise that it is not possible to objectively study the mind, and therefore that psychologists should limit their attention to the study of behavior itself. Psychologists are conducting surveys on behaviourism.
CognitiveCognition is exploring the science of mind. It is mind who accurately isolates cause and effect experiments, and the experimenters should be neutral in their investigations. The study of mental processes, including perception, thinking, memory, and judgments
Social-culturalYou might have attended a lecture by the psychologist who uses all above said terms in his presentation. The study of how the social situations and the cultures in which people find themselves influence thinking and behavior. To accurately infer cause and effect relationship, experimenters should be versed with updated knowledge of socio-cultural domain.

Careers & Disciplines in Psychology

Knowledge of PsychologyDetailed DescriptionCareers & Disciplines
Biopsychology and neuroscienceThis field examines the physiological bases of behavior in animals and humans by studying the functioning of different brain areas and the effects of hormones and neurotransmitters on behavior.Most bio-psychologists work in research settings—for instance, at universities, for the federal government, and in private research labs.
Clinical and counseling psychologyThese are the largest fields of psychology. In present time, psychologists are also therapists. The focus is on the assessment, diagnosis, causes, and treatment of mental disorders.Clinical and counseling psychologists provide therapy to patients with the goal of improving their life experiences. They work in hospitals, schools, social agencies, and in private practice. Because the demand for this career is high, entry to academic programs is highly competitive
Cognitive psychologyThis field uses sophisticated research methods, including reaction time and brain imaging to study memory, language, and thinking of humans.Cognitive psychologists work primarily in research settings, although some (such as those who specialize in human-computer interactions) consult for businesses.
Developmental psychologyCognitive psychologists work primarily in research settings, although some (such as those who specialize in human-computer interactions) consult for businesses.Many work in research settings, although others work in schools and community agencies to help improve and evaluate the effectiveness of intervention programs such as Head Start
Forensic psychologyForensic psychologists apply psychological principles to understand the behavior of judges, attorneys, courtroom juries, and others in the criminal justice system.Forensic psychologists work in the criminal justice system. They may testify in court and may provide information about the reliability of eyewitness testimony and jury selection.
Health psychologyHealth psychologists are concerned with understanding how biology, behavior, and the social situation influence health and illnessHealth psychologists work with medical professionals in clinical settings to promote better health, conduct research, and teach at universities
Industrial-organizational and environmental psychologyIndustrial-organizational psychology applies psychology to the workplace with the goal of improving the performance and well-being of employeesThere are a wide variety of career opportunities in these fields, generally working in businesses. These psychologists help select employees, evaluate employee performance, and examine the effects of different working conditions on behavior.

They may also work to design equipment and environments that improve employee performance and reduce accidents.
Personality psychologyThese psychologists study people and the differences among them. The goal is to develop theories that explain the psychological processes of individuals, and to focus on individual differences.Most work in academic settings, but the skills of personality psychologists are also in demand in business— for instance, in advertising and marketing. PhD programs in personality psychology are often connected with programs in social psychology.
School and educational psychologyThis field studies how people learn in school, the effectiveness of school programs, and the psychology of teachingSchool psychologists work in elementary and secondary schools or school district offices with students, teachers, parents, and administrators.

Sports psychologyThis field studies the psychological aspects of sports behavior. The goal is to understand the psychological factors that influence performance in sports, including the role of exercise and team interactionsSports psychologists work in gyms, schools, professional sports teams, and other areas where sports are practiced

Research on Animals in Psychology

Animals make up an important part of the natural world, and because some research cannot be conducted using humans, animals are also participants in psychological research.

Most psychological research using animals is now conducted with rats, mice, and birds, and the use of other animals in research is declining.

As with ethical decisions involving human participants, a set of basic principles has been developed that helps researchers make informed decisions about such research; a summary is shown below.

Animal research in psychology can provide valuable insights into behavior and mental processes, but must be conducted ethically and with caution when generalizing findings to humans. Alternatives to animal research are also being explored and used in psychology.

APA Guidelines on Humane Care and Use of Animals in Research

The following are some of the most important ethical principles from the American Psychological Association’s guidelines on research with animals.

  • Psychologists acquire, care for, use, and dispose of animals in compliance with current federal, state, and local laws and regulations, and with professional standards.
  • Psychologists trained in research methods and experienced in the care of laboratory animals supervise all procedures involving animals and are responsible for ensuring appropriate consideration of their comfort, health, and humane treatment.
  • Psychologists ensure that all individuals under their supervision who are using animals have received instruction in research methods and in the care, maintenance, and handling of the species being used, to the extent appropriate to their role.
  • Psychologists make reasonable efforts to minimize the discomfort, infection, illness, and pain of animal subjects.
  • Psychologists use a procedure subjecting animals to pain, stress, or privation only when an alternative procedure is unavailable and the goal is justified by its prospective scientific, educational, or applied value.
  • Psychologists perform surgical procedures under appropriate anesthesia and follow techniques to avoid infection and minimize pain during and after surgery. Biological psychology is of utmost importance these days.

When it is appropriate that an animal’s life be terminated, psychologists proceed rapidly, with an effort to minimize pain and in accordance with accepted procedures.

Psychology provides us with a comprehensive understanding of human behavior, which helps us to improve our own behavior and interactions with others.

There are several different types of psychological disorders, including: Anxiety disorders such as generalized anxiety disorder, panic disorder, and phobias. Mood disorders such as depression, bipolar disorder, and seasonal affective disorder. Personality disorders such as borderline personality disorder, narcissistic personality disorder, and antisocial personality disorder.

Moreover, it includes Schizophrenia and other psychotic disorders, Obsessive-compulsive and related disorders, Trauma and stress-related disorders, Eating disorders Substance-related and addictive disorders.

Psychology plays a vital role in mental health treatment, as it provides the knowledge and tools necessary to understand, diagnose, and treat mental health conditions.

There are some ways that psychology contributes to mental health treatment like; Assessment and diagnosis, Treatment planning, Therapy and counseling, Crisis intervention, Research and advocacy.

Overall, psychology plays a critical role in mental health treatment, providing the knowledge, skills, and support necessary to help individuals live healthy, fulfilling lives.

Psychologists use some of the common methods for diagnosis like; Clinical Interviews, Psychological Tests, Diagnostic and Statistical Manual of Mental Disorders (DSM), Behavioral Observation, and Medical Tests.

It’s important to note that genetics and the environment can interact with each other in complex ways. For example, a person may have a genetic predisposition to a certain behavior or condition, but the expression of that gene may be influenced by environmental factors.

Likewise, environmental factors can sometimes trigger changes in a person’s DNA, which can affect their behavior or mental health outcomes. Understanding the interplay between genetics and environment is an important area of research in psychology and other related fields.

Personality refers to a person’s unique set of traits, characteristics, and tendencies that shape their thoughts, emotions, and behaviors. While personality can be a powerful predictor of behavior, it’s important to note that other factors can also influence behavior, such as situational factors and cultural norms.

  • Emotions can motivate us to take action in pursuit of a goal or to avoid a threat. It can also influence our decision-making processes, biasing us towards certain choices or actions.
  • It can also shape the way we interact with others, influencing our social behavior and communication.
  • It can also trigger physiological responses in the body, such as changes in heart rate, breathing, and hormone levels.

Psychology can provide valuable insights and tools for navigating the challenges and opportunities of everyday life. Whether you’re looking to improve your relationships, enhance your performance, or cope with stress, psychology can provide practical strategies for achieving your goals.
