The study of the emotional development of infants and children is relatively new, having been studied empirically only during the past few decades. Researchers have approached this area from a variety of theoretical perspectives, including those of social constructionism, differential emotion theory, and social learning theory. Each of these approaches explores the way infants and children develop…
Emotional intelligence (EI) is sometimes referred to as emotional quotient or emotional literacy. Individuals with emotional intelligence are able to relate to others with compassion and empathy, have well-developed social skills, and use this emotional awareness to direct their actions and behavior. The term was coined in 1990 by psychologists John Mayer and Peter Salovey. In 1995, psychologist/j…
In contrast to moods, which are generally longer-lasting, emotions are transitory, with relatively well-defined beginnings and endings. They also have valence, meaning that they are either positive or negative. Subjectively, emotions are experienced as passive phenomena. Even though it is possible to exert a measure of control over one's emotions, they are not initiated—they happen t…
While most forms of psychotherapy require some degree of empathy on the part of the counselor or therapist, the client-centered therapy pioneered by Carl Rogers places particular emphasis on this quality as part of the therapeutic experience. Instead of looking at the client from outside (external frame of reference), the client-centered therapist attempts to see things as they actually look to th…
Psychologists prefer to learn about behavior through direct observation or experience. This approach reflects what is called empiricism. Psychologists are well-known for creating experiments, conducting interviews and using surveys, and carrying out case studies. The common feature of these approaches is that psychologists wait until observations are made before they draw any conclusions about the…
Encounter groups are formed, usually under the guidance and leadership of a psychologists or therapist, to provide an environment for intensive interaction. In general, because the therapy takes place in a group setting, one of the goals of the encounter group is to improve the participants' interpersonal skills. A typical encounter group may consist of fewer that ten persons, one of whom i…
The endocrine glands—the pineal, pituitary, thyroid, parathyroids, thymus, adrenals, pancreas and gonads (ovaries or testes)—comprise the endocrine system. The hypothalamus, the gland in the brain which serves as the command center, operates the endocrine system through the pituitary, a pea-sized gland located under it, which directs the work of all the other glands. The thyroid, a g…
The relative importance of heredity and environment in shaping human lives—nature versus nurture— has long been a topic of debate taken up by thinkers as diverse as John Locke, Charles Darwin, and Sigmund Freud, and forms part of current policy debates in areas Cross-section of a human adrenal gland, one of the endocrine glands.

Epilepsy, from the Greek word for seizure, is a recurrent demonstration of a brain malfunction. The outward signs of epilepsy may range from only a slight smacking of the lips or staring into space to a generalized convulsion. It is a condition that can affect anyone of any age, sex, or race. The number of people with epilepsy is not known. Some authorities say that up to 0.5% of the population ar…
The equilibrium sense, generally associated with balance, provides feedback about the positions and movements of our heads and bodies in space. The other system—the kinesthetic sense—tells us about the orientation of different parts of our bodies in relation to each other. While the kinesthetic information needed by the brain comes from joints and muscle fibers throughout the body, t…
Erik Erikson was born in Frankfurt, Germany, to Danish parents. As a youth, he was a student and teacher of art. While teaching at a private school in Vienna, he became acquainted with Anna Freud, the daughter of Sigmund Freud. Erikson underwent psychoanalysis, and the experience made him decide to become an analyst himself. He was trained in psychoanalysis at the Vienna Psychoanalytic Institute a…
Ethics are rules for behavior, based on beliefs about how things should be. Ethical statements involve: 1) assumptions about humans and their capacities; 2) logical rules extending from these assumptions; and 3) notions of what is good and desirable. Ethical systems (sets of rules for acceptable behavior) concern the "shoulds" and "should nots" of life, the principles a…
The adjective ethnic is derived from the Greek noun ethnos, which means race, people, nation, and tribe. Although the modern term has a narrower connotation, denoting primarily people, vestiges of the older, more inclusive meaning still remain, particularly in types of discourse where the concepts of race and nationality are used interchangeably. Matters get even more complicated when the concept …
Ethnocentrism is a general belief that the ethnic group with which an individual is identified is superior to all other ethnic groups. Consequently, the individual persistently uses membership in the ethnic group as a primary criterion in the formation of relationships with others, and in evaluating or making judgments concerning other individuals. The term sociocentrism is sometimes used as a syn…
The pioneering work of Konrad Lorenz and Niko Tinbergen in the 1930s established a theoretical foundation for ethology, which has had an effect on such wide-ranging disciplines as genetics, anthropology, and political science in addition to psychology. Ethologists believe that an animal must be studied on its own terms rather than primarily in relation to human beings, with a focus on its normal b…
Psychological etiology refers to the scientific investigation into the origins of a disorder that cannot be explained biologically. Etiology is complicated by the fact that most disorders have more than one cause. Early etiological theories were the Freudian and post-Freudian psychoanalytic beliefs. Sigmund Freud attributed mental or neurotic disorders to deep-seated or hidden psychic motivations.…
As Charles Darwin's ideas on evolutionary theory gained acceptance in the late 1800s, the public's faith in science as a source for social remedies increased in popularity, and scientists have looked for ways to "improve" humanity. British scientist Francis Galton introduced the ideas that led to a scientific approach to eugenics, including the concept of "positi…
Existential psychology is an approach to psychology and psychotherapy that is based on several premises, including: understanding that a "whole" person is more than the sum of his or her parts; understanding people by examining their interpersonal relationships, understanding that people have many levels of self-awareness that can be neither ignored nor put into an abstract context, …
In simple psychological experiments, one characteristic—the independent variable—is manipulated by the experimenter to enable the study of its effects on another characteristic—the dependent variable. In many experiments, the independent variable is a characteristic that can either be present or absent. In these cases, one group of subjects represent the experiment group, wher…
Psychologists conduct experiments in order to isolate causes and effects. Ultimately, explaining human behavior consists of identifying the factors that have a causal influence on how we think or act. The most effective way to investigate causation is through experimentation. Different aspects of an experiment are best explained by providing an example. Suppose a researcher wants to find out if su…
Experimental psychologists work to understand the underlying causes of behavior by studying humans and animals. Animals are studied within and outside laboratory settings for a variety of reasons. A researcher may wish to learn more about a particular species, to study how different species are interrelated, to investigate the evolutionary significance of certain behaviors, or to learn more about …
In classical/respondent conditioning, the learned response disappears when the association between conditioned and unconditioned stimuli is eliminated. For example, when a conditioned stimulus (a light) is presented with an unconditioned stimulus (meat), a dog may be trained to salivate in response to the conditioned stimulus. If the unconditioned stimulus does not appear at least some of the time…
Extroverts are people who are often leaders, work well in groups, and prefer being with others to being alone. Other personality traits often associated with extroversion include optimism, risk taking, and love of excitement and change. People who are extroverts prefer having company and tend to have many friends. Extroversion is generally defined in comparison to its opposite, introversion, which…
Hans Eysenck's obituary in the New York Times called him "one of the most distinguished, prolific, and maddeningly perverse psychologists of his generation." This accurately sums up a long career that Eysenck claimed he entered almost by accident. As a personality and behavior theorist, he popularized the terms "introvert" and "extrovert," and he cr…
The majority of persons suffering from mental retardation fall into the category of familial retardation rather than that of clinical retardation, which usually has neurological or other organic causes. Persons with familial retardation typically have IQs ranging from 55-69 and show no signs of physical disability. Environmental causes thought to contribute to familial retardation include the qual…
Family size is a significant factor in child development, but must be considered as only one part of a larger picture, however. Other factors, such as the parents' personality traits, and the gender and spacing of the children, contribute significantly to the formation of a child's personality. Children of large families have a greater opportunity to learn cooperation at an early age…
Family therapy is generally initiated because of psychological or emotional problems experienced by a single family member, often a child or adolescent. These problems are treated as symptomatic of dysfunction within the family system as a whole. The therapist focuses on the interaction between family members, analyzing the role played by each member in maintaining the system. Family therapy can b…
Family is broadly defined as any two people who are related to each other through a genetic connection, adoption, marriage, or by mutual agreement. Family members share emotional and economic bonds. The term nuclear family is used to refer to family members who live together and share emotional, economic, and social responsibilities. The nuclear family is often comprised of a married couple who ar…
A fantasy is inspired by imagination characterized by mental images that do not necessarily have any relationship to reality. In psychoanalysis, fantasy is regarded as a defense mechanism. For example, after being reprimanded by a supervisor, a worker may fantasize about taking over the company and firing the supervisor. Similarly, a child may fantasize about running away from home in retaliation …
Fear is one of the primary emotions, together with joy, anger, and grief. Fear generally refers to feelings elicited by tangible, realistic dangers, as opposed to anxiety, which often arises out of proportion to the actual threat or danger involved. Fear may be provoked by exposure to traumatic situations, observations of other people exhibiting fear, or the receipt of frightening information. Rep…
