In a study of the effects of anxiety on self-esteem, anxiety would be the dependent variable.
Within the context of psychology, social psychology is the scientific study of how people's thoughts, feelings, and behaviors are influenced by the actual, imagined, or implied presence of others. By this definition, scientific refers to the empirical method of investigation. The terms thoughts, feelings, and behaviors include all psychological variables that are measurable in a human being. The statement that others' presence may be imagined or implied suggests that we are prone to social influence even when no other people are present, such as when watching television, or following internalized cultural norms. Social psychologists typically explain human behavior as a result of the interaction of mental states and immediate social situations. In general, social psychologists have a preference for laboratory-based, empirical findings. Social psychology theories tend to be specific and focused, rather than global and general.
Social psychologists therefore deal with the factors that lead us to behave in a given way in the presence of others, and look at the conditions under which certain behavior/actions and feelings occur. Social psychology is concerned with the way these feelings, thoughts, beliefs, intentions and goals are constructed and how such psychological factors, in turn, influence our interactions with others.

There are at least two senses in which the term philosophy is used: a formal and an informal sense. In the formal sense, philosophy is an academic study of the fields aesthetics, ethics, epistemology, logic, metaphysics, as well as social and political philosophy. One's "philosophy of life" is philosophy in the informal sense, as a way of life whose focus is resolving the existential questions about the human condition.
Variables used in an experiment or modelling can be divided into three types: "dependent variable", "independent variable", or other. The "dependent variable" represents the output or effect, or is tested to see if it is the effect. The "independent variables" represent the inputs or causes, or are tested to see if they are the cause. Other variables may also be observed for various reasons.
In social psychology, terror management theory (TMT) proposes a basic psychological conflict that results from having a desire to live but realizing that death is inevitable. This conflict produces terror, and is believed to be unique to human beings. Moreover, the solution to the conflict is also generally unique to humans: culture. According to TMT, cultures are symbolic systems that act to provide life with meaning and value. Cultural values therefore serve to manage the terror of death by providing life with meaning. The theory was originally proposed by Jeff Greenberg, Sheldon Solomon, and Tom Pyszczynski.
The simplest examples of cultural values' managing the terror of death are those that purport to offer literal immortality (e.g. belief in afterlife, religion). However, TMT also argues that other cultural values—including those that are seemingly unrelated to death—offer symbolic immortality. For example, value of national identity, posterity, cultural perspectives on sex, and human superiority over animals have all been linked to death concerns in some manner. In many cases these values are thought to offer symbolic immortality by providing the sense that one is part of something greater that will ultimately outlive the individual (e.g. country, lineage, species).
Social anxiety disorder (SAD) (DSM-5 300.23), also known as social phobia, is the most common anxiety disorder. It is characterized by intense fear in one or more social situations, causing considerable distress and impaired ability to function in at least some parts of daily life. These fears can be triggered by perceived or actual scrutiny from others. While the fear of social interaction may be recognized by the person as excessive or unreasonable, overcoming it can be quite difficult. Some people suffering from social anxiety disorder fear a wide range of social situations while others may only show anxiety in performance situations. In the latter case, the specifier "performance only" is added to the diagnosis.
Social anxiety disorder is known to appear at an early age in most cases. 50% of those who develop this disorder have developed it by the age of 11 and 80% have developed it by age 20. This early age of onset may lead to people with social anxiety disorder being particularly vulnerable to depressive illnesses, drug abuse and other psychological conflicts. Physical symptoms often accompanying social anxiety disorder include excessive blushing, sweating (hyperhidrosis), trembling, palpitations and nausea. Stammering may be present, along with rapid speech. Panic attacks can also occur under intense fear and discomfort. An early diagnosis may help minimize the symptoms and the development of additional problems, such as depression. Some sufferers may use alcohol or other drugs to reduce fears and inhibitions at social events. It is common for sufferers of social phobia to self-medicate in this fashion, especially if they are undiagnosed, untreated, or both; this can lead to alcoholism, eating disorders or other kinds of substance abuse. SAD is sometimes referred to as an 'illness of lost opportunities'. Standardized rating scales such as the Social Phobia Inventory, the SPAI-B and Liebowitz Social Anxiety Scale can be used to screen for social anxiety disorder and measure the severity of anxiety.
Science of drugs including their origin, composition, pharmacokinetics,
pharmacodynamics, therapeutic use, and toxicology.
Pharmacology (from Greek φάρμακον, pharmakon, "poison" in classic Greek; "drug" in modern Greek; and -λογία, -logia "study of", "knowledge of") is the branch of medicine and biology concerned with the study of drug action, where a drug can be broadly defined as any man-made, natural, or endogenous (within the body) molecule which exerts a biochemical and/or physiological effect on the cell, tissue, organ, or organism. More specifically, it is the study of the interactions that occur between a living organism and chemicals that affect normal or abnormal biochemical function. If substances have medicinal properties, they are considered pharmaceuticals.
