Nostalgic

Nostalgia is a sentimentality for the past, typically for a period or place with happy personal associations. The word ''nostalgia'' is a learned formation of a Greek compound, consisting of (''nóstos''), meaning "homecoming", a Homeric word, and (''álgos''), meaning "sorrow" or "despair", and was coined by a 17th-century medical student to describe the anxieties displayed by Swiss mercenaries fighting away from home. Described as a medical condition—a form of melancholy—in the Early Modern period, it became an important trope in Romanticism.

Nostalgia is associated with a longing for the past, its personalities, possibilities, and events, especially the " good ol' days" or a "warm childhood". There is a predisposition, caused by cognitive biases such as rosy retrospection, for people to view the past more favourably and future more negatively. When applied to one's beliefs about a society or institution, this is called declinism, which has been described as "a trick of the mind" and as "an emotional strategy, something comforting to snuggle up to when the present day seems intolerably bleak."

The scientific literature on nostalgia usually refers to nostalgia regarding one's personal life and has mainly studied the effects of nostalgia as induced during these studies. Emotion is a strong evoker of nostalgia due to the processing of these stimuli first passing through the amygdala, the emotional seat of the brain. These recollections of one's past are usually important events, people one cares about, and places where one has spent time. Cultural phenomena such as music, movies, television shows, and video games, as well as natural phenomena such as weather and environment can also be strong triggers of nostalgia.

Functions

Nostalgia's definition has changed greatly over time. Consistent with its Greek word roots meaning "homecoming" and "pain," nostalgia was for centuries considered a potentially debilitating and sometimes fatal medical condition expressing extreme homesickness. The modern view is that nostalgia is an independent, and even positive, emotion that many people experience often. Nostalgia has been found to have important psychological functions, such as to improve mood, increase social connectedness, enhance positive self-regard, and provide existential meaning. Many nostalgic reflections serve more than one function, and overall seem to benefit those who experience them. Such benefits may lead to a chronic disposition or personality trait of "nostalgia proneness." Nostalgia has also been associated with learning and memory consolidation.

Improve mood

Although nostalgia is often triggered by negative feelings, it results in increasing one's mood and heightening positive emotions, which can stem from feelings of warmth or coping resulting from nostalgic reflections. One way to improve mood is to effectively cope with problems that hinder one's happiness. Batcho (2013) found that nostalgia proneness positively related to successful methods of coping throughout all stages—planning and implementing strategies, and reframing the issue positively. These studies led to the conclusion that the coping strategies that are likely among nostalgia-prone people often lead to benefits during stressful times. Nostalgia can be connected to more focus on coping strategies and implementing them, thus increasing support in challenging times.

Increase social connectedness

Nostalgia also sometimes involves memories of people one was close to, and thus it can increase one's sense of social support and connections. Nostalgia is also triggered specifically by feelings of loneliness, but counteracts such feelings with reflections of close relationships. According to Zhou et al. (2008), lonely people often have lesser perceptions of social support. Loneliness, however, leads to nostalgia, which actually increases perceptions of social support. Thus, Zhou and colleagues (2008) concluded that nostalgia serves a restorative function for individuals regarding their social connectedness.

A desire for more social interaction is often the motivation for historical reenactments, which bring together people with a shared nostalgia for historical periods of past times. These events' hands-on, improvisational natures often facilitate socialization.

Enhance positive self-regard

Nostalgia serves as a coping mechanism and helps people to feel better about themselves. Vess et al. (2012) found that the subjects who thought of nostalgic memories showed greater accessibility of positive characteristics than those who thought of exciting future experiences. Additionally, in a second study conducted, some participants were exposed to nostalgic engagement and reflection while the other group was not. The researchers looked again at self-attributes and found that the participants who were not exposed to nostalgic experiences reflected a pattern of selfish and self-centered attributes. Vess et al. (2012), however, found that this effect had weakened and become less powerful among the participants who engaged in nostalgic reflection.

Provide existential meaning

Nostalgia helps increase one's self-esteem and meaning in life by buffering threats to well-being and also by initiating a desire to deal with problems or stress. Routledge (2011) and colleagues found that nostalgia correlates positively with one's sense of meaning in life. The second study revealed that nostalgia increases one's perceived meaning in life, which was thought to be mediated by a sense of social support or connectedness. Thirdly, the researchers found that threatened meaning can even act as a trigger for nostalgia, thus increasing one's nostalgic reflections. By triggering nostalgia, though, one's defensiveness to such threat is minimized as found in the fourth study. The final two studies found that nostalgia is able to not only create meaning but buffer threats to meaning by breaking the connection between a lack of meaning and one's well-being. Follow-up studies also completed by Routledge in 2012 not only found meaning as a function of nostalgia, but also concluded that nostalgic people have greater perceived meaning, search for meaning less, and can better buffer existential threat.

Promote psychological growth

Nostalgia makes people more willing to engage in growth-oriented behaviors and encourages them to view themselves as growth-oriented people. Baldwin & Landau (2014) found that nostalgia leads people to rate themselves higher on items like "I am the kind of person who embraces unfamiliar people, events, and places." Nostalgia also increased interest in growth-related behavior such as "I would like to explore someplace that I have never been before." In the first study, these effects were statistically mediated by nostalgia-induced positive affect—the extent to which nostalgia made participants feel good. In the second study, nostalgia led to the same growth outcomes but the effects were statistically mediated by nostalgia-induced self-esteem.

As a deception

One recent study critiques the idea of nostalgia, which in some forms can become a defense mechanism by which people avoid the historical facts. This study looked at the different portrayals of apartheid in South Africa and argued that nostalgia appears as two ways,Boym, S. (2001). The future of nostalgia. New York, NY: Basic Books 'restorative nostalgia' a wish to return to that past, and 'reflective nostalgia' which is more critically aware.

As a comfort

Reliving past memories may provide comfort and contribute to mental health. One notable recent medical study has looked at the physiological effects thinking about past 'good' memories can have. They found that thinking about the past 'fondly' actually increased perceptions of physical warmth.

As a political tool

In a 2014 study conducted by Routledge, he and a team observed that the more people reported having major disruptions and uncertainties in their lives, the more they nostalgically longed for the past. Routledge suggests that by invoking the idea of an idealized past, politicians can provoke the social and cultural anxieties and uncertainties that make nostalgia especially attractive—and effective—as a tool of political persuasion.

Trigger factors

Cultural

Books

A person can deliberately trigger feelings of nostalgia by listening to familiar music, looking at old photos, or visiting comforting environments of the past. With this knowledge widely available, many books have been published specifically to evoke the feeling of nostalgia.

Music

Hearing an old song can bring back memories for a person. A song heard once at a specific moment and then not heard again until a far later date will give the listener a sense of nostalgia for the date remembered and events that occurred then. However, if it is heard throughout life, it may lose its association with any specific period or experience.

Movies

Old movies can trigger nostalgia. This is particularly true for generations who grew up as children during specific film eras such as the animation renaissance of the 1990s. Rewatching classic movies can be therapeutic in nature, healing emotional wounds using happy childhood memories.

TV shows

Old television shows can trigger nostalgia. People gravitate towards shows they watched as children, as the memories from one's youth are often the most significant of their lives.

Video games

Old video games can trigger nostalgia. Retrogaming has become a recreational activity among older generations who played them as children.

Environmental

Nature-based factors such as weather and temperature can trigger nostalgia. Scientific studies have shown that cold weather makes people more nostalgic, while nostalgia causes people to feel warmer. In some societies, elements of nature often trigger a nostalgia for past times when nature played a larger role in culture.
Environmental philosopher Glenn Albrecht coined the term 'solastalgia' in his 2003 book ''Solastalgia: a new concept in human health and identity''. The word is formed from the Latin sōlācium (comfort) and the Greek root ἄλγος (pain, suffering) to describe a form of emotional or existential distress caused by environmental destruction. Nostalgia differs from solastalgia because nostalgia is typically generated by spatial separation from important places or persons (one's home, one's family, or loved ones) with which it is often possible, in principle, to reconnect. With solastalgia, in contrast, the grief is typically caused by environmental destruction, so the separation between subject and object is ontological rather than spatial: it is permanent and unbridgeable, and can be experienced while continuing to occupy the same irreversibly degraded place.

Other aspects

As a medical condition

The term was coined in 1688 by Johannes Hofer (1669–1752) in his Basel dissertation. Hofer introduced ''nostalgia'' or ''mal du pays'' "homesickness" for the condition also known as ''mal du Suisse'' "Swiss illness", because of its frequent occurrence in Swiss mercenaries who in the plains of Switzerland were pining for their landscapes. Symptoms were also thought to include fainting, high fever, and death.

English ''homesickness'' is a loan translation of ''nostalgia''. Sir Joseph Banks used the word in his journal during the first voyage of Captain Cook. On 3 September 1770 he stated that the sailors "were now pretty far gone with the longing for home which the Physicians have gone so far as to esteem a disease under the name of Nostalgia", but his journal was not published in his lifetime. Cases resulting in death were known and soldiers were sometimes successfully treated by being discharged and sent home. Receiving a diagnosis was, however, generally regarded as an insult.

In the eighteenth century, scientists were looking for a locus of nostalgia, a nostalgic bone. By the 1850s nostalgia was losing its status as a particular disease and coming to be seen rather as a symptom or stage of a pathological process. It was considered as a form of melancholia and a predisposing condition among suicides. Nostalgia was, however, still diagnosed among soldiers as late as the American Civil War. By the 1870s interest in nostalgia as a medical category had almost completely vanished. Nostalgia was still being recognized in both the First and Second World Wars, especially by the American armed forces. Great lengths were taken to study and understand the condition to stem the tide of troops leaving the front in droves (see the BBC
