Psychological horror aims to create discomfort by exposing common or universal psychological and emotional vulnerabilities/fears and revealing the darker parts of the human psyche that most people may repress or deny. This idea is referred to in Jungian psychology as the archetypal shadow characteristics: suspicion, distrust, self-doubt and paranoia of others, themselves and the world. Thus, elements of psychological horror focus on mental conflict. These become important as the characters face perverse situations, sometimes involving the supernatural, immorality and conspiracies. While other horror media emphasize fantastical situations such as attacks by monsters, psychological horror tends to keep the monsters hidden and to involve situations more grounded in artistic realism.
Plot twists are an often used device. Characters commonly face internal battles with subconscious desires such as romantic lust and the desire for petty revenge. In contrast, splatter fiction focuses on bizarre, alien evil to which the average viewer cannot easily relate. At times, the psychological horror and splatter subgenres overlap, such as in the French horror film High Tension. 
The novel Silence of the Lambs written by Thomas Harris, Robert Bloch novels such as Psycho and American Gothic, Stephen King novels such as Carrie, Misery, The Girl Who Loved Tom Gordon, The Shining and Koji Suzuki's Ring are some examples of psychological horror.
Psychological horror films differ from the traditional horror film, where the source of the fear is typically something material, such as creatures, monsters or aliens, as well as the splatter film, which derives its effects from gore and graphic violence, in that tension is built through atmosphere, eerie sounds and exploitation of the viewer's and the character's psychological fears.
Roman Polanski directed two films which are considered quintessential psychological horror: Repulsion (1965) and Rosemary's Baby (1968). Stanley Kubrick's 1980 film The Shining is another particularly well-known example of the genre. The Changeling (1980) directed by Peter Medak is another good example of a psychological haunting story. The Silence of the Lambs (1991) directed by Jonathan Demme is another good example of psychological horror, whilst also incorporating elements of the thriller genre.
The subgenre is a staple in Asian countries. Japanese horror films, commonly referred to as "J-horror", have been noted to be generally of a psychological horror nature. Notable examples are Ring (1998) and the Ju-on series. Another influential category is the Korean horror films, commonly referred to as "K-horror". Notable examples are A Tale of Two Sisters (2003), Hansel and Gretel (2007) and Whispering Corridors (1998). A landmark film from the Philippines, Kisapmata (1981), is an example of psychological horror.
