Socioemotional Selectivity Theory
Socioemotional selectivity theory (SST; developed by Stanford psychologist Laura L. Carstensen) is a life-span theory of motivation. The theory maintains that as time horizons shrink, as they typically do with age, people become increasingly selective, investing greater resources in emotionally meaningful goals and activities. According to the theory, motivational shifts also influence cognitive processing. Aging is associated with a relative preference for positive over negative information in individuals who have had rewarding relationships.Santrock, J.W. (2008). ''A Topical Approach to Life-Span Development''. New York, NY: McGraw-Hill. This selective narrowing of social interaction maximizes positive emotional experiences and minimizes emotional risks as individuals become older. According to this theory, older adults systematically hone their social networks so that available social partners satisfy their emotional needs. The theory also focuses on the types of goals that indivi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Future Foreshortening
The future is the time after the past and present. Its arrival is considered inevitable due to the existence of time and the laws of physics. Due to the apparent nature of reality and the unavoidability of the future, everything that currently exists and will exist can be categorized as either permanent, meaning that it will exist forever, or temporary, meaning that it will end. In the Occidental view, which uses a linear conception of time, the future is the portion of the projected timeline that is anticipated to occur. In special relativity, the future is considered absolute future, or the future light cone. In the philosophy of time, presentism is the belief that only the present exists and the future and the past are unreal. Religions consider the future when they address issues such as karma, life after death, and eschatologies that study what the end of time and the end of the world will be. Religious figures such as prophets and diviners have claimed to see into ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Opportunity Cost
In microeconomic theory, the opportunity cost of a particular activity is the value or benefit given up by engaging in that activity, relative to engaging in an alternative activity. More effective it means if you chose one activity (for example, an investment) you are giving up the opportunity to do a different option. The optimal activity is the one that, net of its opportunity cost, provides the greater return compared to any other activities, net of their opportunity costs. For example, if you buy a car and use it exclusively to transport yourself, you cannot rent it out, whereas if you rent it out you cannot use it to transport yourself. If your cost of transporting yourself without the car is more than what you get for renting out the car, the optimal choice is to use the car yourself. In basic equation form, opportunity cost can be defined as: "Opportunity Cost = (returns on best Forgone Option) - (returns on Chosen Option)." The opportunity cost of mowing one’s own l ...

Norwegian People
Norwegians ( no, nordmenn) are a North Germanic ethnic group and nation native to Norway, where they form the vast majority of the population. They share a common culture and speak the Norwegian language. Norwegians are descended from the Norse of the Early Middle Ages who formed a unified Kingdom of Norway in the 9th century. During the Viking Age, Norwegians and other Norse peoples conquered, settled and ruled parts of the British Isles, the Faroe Islands, Iceland and Greenland. Norwegians are closely related to other North Germanic peoples and descendants of the Norsemen such as Danes, Swedes, Icelanders and the Faroe Islanders, as well as groups such as the Scots whose nation they significantly settled and left a lasting impact in. The Norwegian language is part of the larger Scandinavian dialect continuum of generally mutually intelligible languages in Scandinavia. Norwegian people and their descendants are found in migrant communities worldwide, notably in the Uni ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Catholic Nun
A nun is a woman who vows to dedicate her life to religious service, typically living under vows of poverty, chastity, and obedience in the enclosure of a monastery or convent.''The Oxford English Dictionary'', vol. X, page 599. The term is often used interchangeably with religious sisters who do take simple vows but live an active vocation of prayer and charitable work. In Christianity, nuns are found in the Roman Catholic, Oriental Orthodox, Eastern Orthodox, Lutheran, and Anglican traditions, as well as other Christian denominations. In the Buddhist tradition, female monastics are known as Bhikkhuni, and take several additional vows compared to male monastics (bhikkhus). Nuns are most common in Mahayana Buddhism, but have more recently become more prevalent in other traditions. Christianity Catholicism In the Catholic tradition, there are many religious institutes of nuns and sisters (the female equivalent of male monks or friars), each with its own charism ...

African-American
African Americans (also referred to as Black Americans and Afro-Americans) are an ethnic group consisting of Americans with partial or total ancestry from sub-Saharan Africa. The term "African American" generally denotes descendants of enslaved Africans who are from the United States. While some Black immigrants or their children may also come to identify as African-American, the majority of first generation immigrants do not, preferring to identify with their nation of origin. African Americans constitute the second largest racial group in the U.S. after White Americans, as well as the third largest ethnic group after Hispanic and Latino Americans. Most African Americans are descendants of enslaved people within the boundaries of the present United States. On average, African Americans are of West/Central African with some European descent; some also have Native American and other ancestry. According to U.S. Census Bureau data, African immigrants generally do not sel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chinese American
Chinese Americans are Americans of Han Chinese ancestry. Chinese Americans constitute a subgroup of East Asian Americans which also constitute a subgroup of Asian Americans. Many Chinese Americans along with their ancestors trace lineage from mainland China, Hong Kong, Macau, Malaysia, Singapore, Taiwan, as well as other regions which are inhabited by large populations of the Chinese diaspora, especially Southeast Asia and some other countries such as Australia, Canada, France, South Africa, New Zealand, and the United Kingdom. Chinese-Americans include Chinese from the Chinese circle and around the world who became naturalized U.S. citizens and their natural-born descendants in the United States. The Chinese American community is the largest overseas Chinese community outside Asia. It is also the third largest community in the Chinese diaspora, behind the Chinese communities in Thailand and Malaysia. The 2016 Community Survey of the US Census estimates a popul ...

European-American
European Americans (also referred to as Euro-Americans) are Americans of European ancestry. This term includes people who are descended from the first European settlers in the United States as well as people who are descended from more recent European arrivals. European Americans have been the largest panethnic group in the United States since about the 17th century. The Spaniards are thought to be the first Europeans to establish a continuous presence in what is now the contiguous United States, with Martín de Argüelles ( 1566) in St. Augustine, then a part of Spanish Florida, and the Russians were the first Europeans to settle in Alaska, establishing Russian America. The first English child born in the Americas was Virginia Dare, born August 18, 1587. She was born in Roanoke Colony, located in present-day North Carolina, which was the first attempt, made by Queen Elizabeth I, to establish a permanent English settlement in North America. In the 2016 American Community ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dot-probe Paradigm
The dot-probe paradigm is a test used by cognitive psychologists to assess selective attention. According to Eysenck, MacLeod & Mathews (1987) and Mathews (2004) the dot-probe task derives directly from research carried out by Christos Halkiopoulos in 1981. Halkiopoulos, later a doctoral student of Eysenck, carried out this research while he was a psychology undergraduate at UCL, under the supervision of professor N.F. Dixon. He introduced an attentional probe paradigm, which he initially used in the auditory modality to assess attentional biases to threatening auditory information, when threatening and non-threatening information was presented simultaneously to both ears in a dichotic listening task (). Halkiopoulos demonstrated attentional biases by measuring reaction times to auditory probes following neutral and emotional words in the attended and the unattended channels. This method was subsequently used in the visual modality by MacLeod, Mathews and Tata (1986) in what came ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Medial Prefrontal Cortex
In mammalian brain anatomy, the prefrontal cortex (PFC) covers the front part of the frontal lobe of the cerebral cortex. The PFC contains the Brodmann areas BA8, BA9, BA10, BA11, BA12, BA13, BA14, BA24, BA25, BA32, BA44, BA45, BA46, and BA47. The basic activity of this brain region is considered to be orchestration of thoughts and actions in accordance with internal goals. Many authors have indicated an integral link between a person's will to live, personality, and the functions of the prefrontal cortex. This brain region has been implicated in executive functions, such as planning, decision making, short-term memory, personality expression, moderating social behavior and controlling certain aspects of speech and language. Executive function relates to abilities to differentiate among conflicting thoughts, determine good and bad, better and best, same and different, future consequences of current activities, working toward a defined goal, prediction of outcomes, ...

Amygdala
The amygdala (; plural: amygdalae or amygdalas; also '; Latin from Greek, , ', 'almond', 'tonsil') is one of two almond-shaped clusters of nuclei located deep and medially within the temporal lobes of the brain's cerebrum in complex vertebrates, including humans. Shown to perform a primary role in the processing of memory, decision making, and emotional responses (including fear, anxiety, and aggression), the amygdalae are considered part of the limbic system. The term "amygdala" was first introduced by Karl Friedrich Burdach in 1822. Structure The regions described as amygdala nuclei encompass several structures of the cerebrum with distinct connectional and functional characteristics in humans and other animals. Among these nuclei are the basolateral complex, the cortical nucleus, the medial nucleus, the central nucleus, and the intercalated cell clusters. The basolateral complex can be further subdivided into the lateral, the basal, and the accessory basal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aging And Memory
Age-related memory loss, sometimes described as "normal aging" (also spelled "ageing" in British English), is qualitatively different from memory loss associated with types of dementia such as Alzheimer's disease, and is believed to have a different brain mechanism. Mild cognitive impairment Mild cognitive impairment (MCI) is a condition in which people face memory problems more often than that of the average person their age. These symptoms, however, do not prevent them from carrying out normal activities and are not as severe as the symptoms for Alzheimer's disease (AD). Symptoms often include misplacing items, forgetting events or appointments, and having trouble finding words. According to recent research, MCI is seen as the transitional state between cognitive changes of normal aging and Alzheimer's disease. Several studies have indicated that individuals with MCI are at an increased risk for developing AD, ranging from one percent to twenty-five percent per year; in one ...
