What Is Psychology

One of the most common questions asked by students new to the study of psychology is "What is psychology?" Misperceptions created by popular media as well as the diverse careers paths of those holding psychology degrees have contributed this confusion.

Psychology is both an applied and academic field that studies the human mind and behavior. Research in psychology seeks to understand and explain thought, emotion, and behavior. Applications of psychology include mental health treatment, performance enhancement, self-help, ergonomics, and many other areas affecting health and daily life.
Answer:
Early Psychology
Psychology evolved out of both philosophy and biology. Such discussions of the two subjects date as far back as the early Greek thinkers such as Aristotle and Socrates. The word psychology is derived from the Greek word psyche, meaning 'soul' or 'mind.'
A Separate Science
The field and study of psychology was truly born when Wilhelm Wundt established the first psychology lab in Leipzig, Germany. Wundt's research utilized a school of thought known as structuralism, which involved describing the structures that compose the mind. This perspective relied heavily on the analysis of sensations and feelings through the use of introspection, a highly subjective process. Wundt believed that properly trained individuals would be able to accurately identify the mental processes that accompanied feelings, sensations, and thoughts.
Schools of Thought
Throughout psychology's history, a number of different schools of thought have thought have formed to explain human thought and behavior. These schools of thought often rise to dominance for a period of time. While these schools of thought are sometimes perceived as competing forces, each perspective has contributed to our understanding of psychology. The following are some of the major schools of thought in psychology.
•Structuralism
•Functionalism
•Psychoanalysis
•Behaviorism
•Humanism
•Cognitivism
Psychology Today
Today, psychologists prefer to use more objective scientific methods to understand, explain, and predict human behavior. Psychological studies are highly structured, beginning with a hypothesis that is then empirically tested. Psychology has two major areas of focus: academic psychology and applied psychology. Academic psychology focuses on the study of different sub-topics within psychology including personality psychology, social psychology, and developmental psychology.

These psychologists conduct basic research that seeks to expand our theoretical knowledge, while other researchers conduct applied research that seeks to solve everyday problems. Applied psychology focuses on the use of different psychological principles to solve real world problems. Examples of applied areas of psychology include forensic psychology, ergonomics, and industrial-organizational psychology. Many other psychologists work as therapists, helping people overcome mental, behavioral, and emotional disorders.
Psychology Research Methods
As psychology moved away from its philosophical roots, psychologists began to employ more and more scientific methods to study human behavior. Today, researchers employ a variety of scientific methods, including experiments, correlational studies, longitudinal studies, and others to test, explain, and predict behavior.
Areas of Psychology
Psychology is a broad and diverse field. A number of different subfields and specialty areas have emerged. The following are some of the major areas of research and application

Evaluating Freud’s Psychosexual Stage Theory

The theory is focused almost entirely on male development with little mention of female psychosexual development.
His theories are difficult to test scientifically. Concepts such as the libido are impossible to measure, and therefore cannot be tested. The research that has been conducted tends to discredit Freud's theory.
Future predictions are too vague. How can we know that a current behavior was caused specifically by a childhood experience? The length of time between the cause and the effect is too long to assume that there is a relationship between the two variables.
Freud's theory is based upon case studies and not empirical research. Also, Freud based his theory on the recollections of his adult patients, not on actual observation and study of children.Find more information about Freud's theory of personality:

The Genital Stage

During the final stage of psychosexual development, the individual develops a strong sexual interest in the opposite sex. Where in earlier stages the focus was solely on individual needs, interest in the welfare of others grows during this stage. If the other stages have been completed successfully, the individual should now be well-balanced, warm, and caring. The goal of this stage is to establish a balance between the various life areas.

The Latent Period

During the latent period, the libido interests are suppressed. The development of the ego and superego contribute to this period of calm. The stage begins around the time that children enter into school and become more concerned with peer relationships, hobbies, and other interests. The latent period is a time of exploration in which the sexual energy is still present, but it is directed into other areas such as intellectual pursuits and social interactions. This stage is important in the development of social and communication skills and self-confidence.

The Phallic Stage

During the phallic stage, the primary focus of the libido is on the genitals. Children also discover the differences between males and females. Freud also believed that boys begin to view their fathers as a rival for the mother’s affections. The Oedipus complex describes these feelings of wanting to possess the mother and the desire to replace the father. However, the child also fears that he will be punished by the father for these feelings, a fear Freud termed castration anxiety.

The term Electra complex has been used to described a similar set of feelings experienced by young girls. Freud, however, believed that girls instead experience penis envy.

Eventually, the child realizes begins to identify with the same-sex parent as a means of vicariously possessing the other parent. For girls, however, Freud believed that penis envy was never fully resolved and that all women remain somewhat fixated on this stage. Psychologists such as Karen Horney disputed this theory, calling it both inaccurate and demeaning to women. Instead, Horney proposed that men experience feelings of inferiority because they cannot give birth to children

The Anal Stage

During the anal stage, Freud believed that the primary focus of the libido was on controlling bladder and bowel movements. The major conflict at this stage is toilet training--the child has to learn to control his or her bodily needs. Developing this control leads to a sense of accomplishment and independence.

According to Freud, success at this stage is dependent upon the way in which parents approach toilet training. Parents who utilize praise and rewards for using the toilet at the appropriate time encourage positive outcomes and help children feel capable and productive. Freud believed that positive experiences during this stage served as the basis for people to become competent, productive, and creative adults.

However, not all parents provide the support and encouragement that children need during this stage. Some parents' instead punish, ridicule, or shame a child for accidents. According to Freud, inappropriate parental responses can result in negative outcomes. If parents take an approach that is too lenient, Freud suggested that an anal-expulsive personality could develop in which the individual has a messy, wasteful, or destructive personality. If parents are too strict or begin toilet training too early, Freud believed that an anal-retentive personality develops in which the individual is stringent, orderly, rigid, and obsessive.

The Oral Stage

.During the oral stage, the infant's primary source of interaction occurs through the mouth, so the rooting and sucking reflex is especially important. The mouth is vital for eating, and the infant derives pleasure from oral stimulation through gratifying activities such as tasting and sucking. Because the infant is entirely dependent upon caretakers (who are responsible for feeding the child), the infant also develops a sense of trust and comfort through this oral stimulation.

The primary conflict at this stage is the weaning process--the child must become less dependent upon caretakers. If fixation occurs at this stage, Freud believed the individual would have issues with dependency or aggression. Oral fixation can result in problems with drinking, eating, smoking, or nail biting.

What is Psychosexual Development

According to Sigmund Freud, personality is mostly established by the age of five. Early experiences play a large role in personality development and continue to influence behavior later in life.

Freud's theory of psychosexual development is one of the best known, but also one of the most controversial. Freud believed that personality develops through a series of childhood stages during which the pleasure-seeking energies of the id become focused on certain erogenous areas. This psychosexual energy, or libido, was described as the driving force behind behavior.

If these psychosexual stages are completed successfully, the result is a healthy personality. If certain issues are not resolved at the appropriate stage, fixation can occur. A fixation is a persistent focus on an earlier psychosexual stage. Until this conflict is resolved, the individual will remain "stuck" in this stage. For example, a person who is fixated at the oral stage may be over-dependent on others and may seek oral stimulation through smoking, drinking, or eating.

What is Psychoanalytic Theory?

Psychoanalytic theory originated with the work of Sigmund Freud. Through his clinical work with patients suffering from mental illness, Freud came to believe that childhood experiences and unconscious desires influenced behavior. Based on his observations, he developed a theory that described development in terms of a series of psychosexual stages. According to Freud, conflicts that occur during each of these stages can have a lifelong influence on personality and behavior.Psychoanalytic theory was an enormously influential force during the first half of the twentieth century. Those inspired and influenced by Freud went on to expand upon Freud's ideas and develop theories of their own. Of these neo-Freudians, Erik Erikson's ideas have become perhaps the best known. Erikson's eight-stage theory of psychosocial development describes growth and change throughout the lifespan, focusing on social interaction and conflicts that arise during different stages of development.Your Task: Begin this lesson by exploring the theories proposed by Freud and Erikson.

Psychoanalytic Theories:

Psychoanalytic theories of development began with the work of Sigmund Freud, who believed that early childhood experiences had a lasting effect on the course of development. Freud’s work was enormously influential and inspired other psychologists to expand upon his work and develop theories of their own. One of the most famous theorists influenced by Freud was Erik Erikson, whose eight-stage theory of human development remains one of the best-known psychological theories.

Introduction to Theories of Development

Theories of development provide a framework for thinking about human growth, development, and learning. But why do we study development? What can we learn from psychological theories of development? If you have ever wondered about what motivates human thought and behavior, understanding these theories can provide useful insight into individuals and society
