Social anxiety is an intense feeling of fear, apprehension or worry regarding any or all social situations or public events. It is sometimes known as social phobia and, less commonly, social trauma. In psychiatry, it is diagnosed as social anxiety disorder, a form of anxiety disorder. According to United States epidemiological data, it is currently the third largest mental health care problem in the world. A number of medical and therapeutic treatments are available.
Sufferers are typically more self-conscious and self-attentive than others. As a result, social phobics tend to limit or remove themselves from situations where they maybe subject to evaluation. Sufferers often recognize their fear is excessive or irrational, yet can't seem to break out of the cycle. As such, the diagnosis of social phobia is made only when the fear leads to problems with occupational functioning, social activities, or interpersonal relationships.

Memory is the ability of the brain to store, retain, and subsequently recall information. Although traditional studies of memory began in the realms of philosophy, the late nineteenth and early twentieth century put memory within the paradigms of cognitive psychology. In the recent decades, it has become one of the principal pillars of a new branch of science that represents a marriage between cognitive psychology and neuroscience, called cognitive neuroscience.
There are several ways of classifying memories, based on duration, nature and retrieval of information. From an information processing perspective there are three main stages in the formation and retrieval of memory:
- Encoding (processing and combining of received information)
- Storage (creation of a permanent record of the encoded information)
- Retrieval/Recall (calling back the stored information in response to some cue for use in some process or activity)

Schizophrenia is a psychiatric diagnosis that describes a mental disorder characterized by impairments in the perception or expression of reality and by significant social or occupational dysfunction. A person experiencing untreated schizophrenia is typically characterized as demonstrating disorganized thinking, and as experiencing delusions or auditory hallucinations.
Although the disorder is primarily thought to affect cognition, it can also contribute to chronic problems with behavior and emotion. Due to the many possible combinations of symptoms, heated debate is ongoing about whether the diagnosis necessarily or adequately describes a disorder, or alternatively whether it might represent a number of disorders. For this reason, Eugen Bleuler deliberately called the disease "the schizophrenias" plural, when he coined the present name.

Asperger syndrome—also referred to as Asperger's syndrome, Asperger's, or AS—is one of five neurobiological pervasive developmental disorders (PDD) that is characterized by deficiencies in social and communication skills. It is considered to be part of the autistic spectrum and is differentiated from other PDDs and from high functioning autism (HFA) in that early development is normal and there is no language delay. It is possible for people with AS to have learning disabilities concurrently with Asperger syndrome. In these cases, differential diagnosis is essential to identify subsequent support requirements. Conversely, IQ tests may show normal or superior intelligence, and standard language development compared with classical autism. The diagnosis of AS is complicated by the lack of adoption of a standardized diagnostic screen, and, instead, the use of several different screening instruments and sets of diagnostic criteria. The exact cause of AS is unknown and the prevalence is not firmly established, due partly to the use of differing sets of diagnostic criteria.

The Milgram experiment was a famous scientific experiment of social psychology, intended to measure the willingness of a participant to obey an authority who instructs the participant to do something that may conflict with the participant's personal conscience.
The experiment was first described in 1963 by Stanley Milgram, a psychologist at Yale University, and later discussed in his 1974 book, Obedience to Authority: An Experimental View.
Graphically, the experimenter (V) orders the subject (L) to give what the subject believes are painful electric shocks to another subject (S), who is actually an actor. Many participants continued to give shocks despite pleas for mercy from the actor, as long as the experimenter kept on ordering them to do so.
The experiments began in July 1961, three months after the start of the trial of Adolf Eichmann in Jerusalem. Milgram devised the experiment to answer the question "Could it be that Eichmann and his million accomplices in the Holocaust were just following orders? Could we call them all accomplices?"
