Sibling Relationship
Siblings play a unique role in one another's lives that simulates the companionship of parents as well as the influence and assistance of friends. Because siblings often grow up in the same household, they have a large amount of exposure to one another, like other members of the immediate family. However, though a sibling relationship can have both hierarchical and reciprocal elements, this relationship tends to be more egalitarian and symmetrical than with family members of other generations. Furthermore, sibling relationships often reflect the overall condition of cohesiveness within a family. Siblings normally spend more time with each other during their childhood than they do with parents or anyone else; they trust and cherish each other, so betrayal by one sibling could cause problems for that person physically as well as mentally and emotionally. Sibling relationships are often the longest-lasting relationship in individuals' lives. Cultural differences The content and co ...

Sibling
A sibling is a relative that shares at least one parent with the subject. A male sibling is a brother and a female sibling is a sister. A person with no siblings is an only child. While some circumstances can cause siblings to be raised separately (such as foster care), most societies have siblings grow up together. This causes the development of strong emotional bonds, with siblinghood considered a unique type of relationship unto itself. The emotional bond between siblings is often complicated and is influenced by factors such as parental treatment, birth order, personality, and personal experiences outside the family. Medically, a full sibling is a first-degree relative and a half sibling is a second-degree relative as they are related by 50% and 25% respectively. Definitions The word ''sibling'' was reintroduced in 1903 in an article in ''Biometrika'', as a translation for the German ''Geschwister'', having not been used since 1425. Siblings or full siblings ( 'full ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Intellectual Giftedness
Intellectual giftedness is an intellectual ability significantly higher than average. It is a characteristic of children, variously defined, that motivates differences in school programming. It is thought to persist as a trait into adult life, with various consequences studied in longitudinal studies of giftedness over the last century. There is no generally agreed definition of giftedness for either children or adults, but most school placement decisions and most longitudinal studies over the course of individual lives have followed people with IQs in the top 2.5 percent of the population—that is, IQs above 130. Definitions of giftedness also vary across cultures. The various definitions of intellectual giftedness include either general high ability or specific abilities. For example, by some definitions, an intellectually gifted person may have a striking talent for mathematics without equally strong language skills. In particular, the relationship between artistic ability ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Westermarck Effect
The Westermarck effect, also known as reverse sexual imprinting, is a psychological hypothesis that people tend not to be attracted to peers with whom they lived like siblings before age six. This hypothesis was first proposed by Finnish anthropologist Edvard Westermarck in his book '' The History of Human Marriage'' (1891) as one explanation for the incest taboo. Research since Westermarck The Westermarck effect has achieved some empirical support.''Inbreeding, Incest, and the Incest Taboo: The State of Knowledge at the Turn of the Century'', Arthur P. Wolf and William H. Durham (Editors), Stanford University Press, 2004, . Introduction Proponents point to evidence from the Israeli kibbutz system, from the Chinese Shim-pua marriage customs, and from closely related families. In the case of the Israeli kibbutzim (collective farms), children were reared somewhat communally in peer groups, based on age, not biological relations.

Incest
Incest ( ) is human sexual activity between family members or close relatives. This typically includes sexual activity between people in consanguinity (blood relations), and sometimes those related by affinity (marriage or stepfamily), adoption, or lineage. It is strictly forbidden and considered immoral in most societies, and can lead to an increased risk of genetic disorders in children. The incest taboo is one of the most widespread of all cultural taboos, both in present and in past societies. Most modern societies have laws regarding incest or social restrictions on closely consanguineous marriages. In societies where it is illegal, consensual adult incest is seen by some as a victimless crime. Some cultures extend the incest taboo to relatives with no consanguinity such as milk-siblings, step-siblings, and adoptive siblings, albeit sometimes with less intensity. Third-degree relatives (such as half-aunt, half-nephew, first cousin) on average have 12.5% common geneti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Avunculate Marriage
An avunculate marriage is a marriage with a parent's sibling or with one's sibling's child—i.e., between an uncle or aunt and their niece or nephew. Such a marriage may occur between biological (consanguine) relatives or between persons related by marriage ( affinity). In some countries, avunculate marriages are prohibited by law, while in others marriages between such biological relatives are both legal and common, though now far less common. If the partners in an avunculate marriage are biologically related, they normally have the same genetic relationship as half-siblings, or a grandparent and grandchild—that is they share approximately 25% of their genetic material. (They are therefore more closely related than partners in a marriage between first cousins, in which on average the members share 12.5% of inherited genetic material, but less than that of a marriage between, for instance, cousin-siblings, in which the partners share 37.5% of their inherited genetic m ...

Cousin Marriage
A cousin marriage is a marriage where the spouses are cousins (i.e. people with common grandparents or people who share other fairly recent ancestors). The practice was common in earlier times, and continues to be common in some societies today, though in some jurisdictions such marriages are prohibited. Worldwide, more than 10% of marriages are between first or second cousins. Cousin marriage is an important topic in anthropology and alliance theory. In some cultures and communities, cousin marriages are considered ideal and are actively encouraged and expected; in others, they are seen as incestuous and are subject to social stigma and taboo. Cousin marriage was historically practiced by indigenous cultures in Indigenous Australians, Australia, Indigenous peoples of the Americas#North America, North America, Indigenous peoples of the Americas#South America, South America, and Polynesians, Polynesia.

Amnon And Tamar By An Unknown Artist, Oil On Canvas, Ca
Amnon ( he, אַמְנוֹן ''’Amnōn'', "faithful") was, in the Hebrew Bible, the oldest son of King David and his second wife, Ahinoam of Jezreel. He was born in Hebron during his father's reign in Judah. He was the heir apparent to the throne of Israel until he was assassinated by his half-brother Absalom to avenge the rape of Absalom's sister Tamar. Biblical account Amnon's background Amnon was born in Hebron to Ahinoam and King David. As the presumptive heir to the throne of Israel, Amnon enjoyed a life of power and privilege. Rape of Tamar Although he was the heir-apparent to David's throne, Amnon is best remembered for the rape of his half-sister Tamar, daughter of David and Maachah. Despite the biblical prohibition on sexual relations between half siblings, Amnon had an overwhelming desire for her. He acted on advice from his cousin, Jonadab son of Shimeah, David's brother, to lure Tamar into his quarters by pretending to be sick and desiring her to cook a speci ...

Sibling Abuse
Sibling abuse includes the physical, psychological, or sexual abuse of one sibling by another. More often than not, the younger sibling is abused by the older sibling, however this is not always the case. Sibling abuse is the most common of family violence in the US, but the least reported. As opposed to sibling rivalry, sibling abuse is characterized by the one-sided treatment of one sibling to another. Sibling abuse has been found to most commonly occur in dysfunctional families where abuse from parents is present. In the US, 40% of children have engaged in physical aggression towards a sibling, and as many as 85% of children have engaged in verbal abuse towards their sibling. Types and prevalence Physical abuse Sibling physical abuse is defined as a sibling deliberately causing violence to another sibling. The abuse can be inflicted with shoving, hitting, slapping, kicking, biting, pinching, scratching, and hair-pulling. Sibling physical abuse is more common than peer bull ...

Alfred Adler
Alfred Adler ( , ; 7 February 1870 – 28 May 1937) was an Austrian medical doctor, psychotherapist, and founder of the school of individual psychology. His emphasis on the importance of feelings of belonging, family constellation and birth order set him apart from Freud and other members of the Vienna Circle. He proposed that contributing to others (Social Interest or ) was how the individual feels a sense of worth and belonging in the family and society. His earlier work focused on inferiority, the inferiority complex, an isolating element which plays a key role in personality development. Alfred Adler considered a human being as an individual whole, and therefore he called his psychology "Individual Psychology" (Orgler 1976). Adler was the first to emphasize the importance of the social element in the re-adjustment process of the individual and to carry psychiatry into the community. A ''Review of General Psychology'' survey, published in 2002, ranked Adler as the 67th most e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parent–offspring Conflict
Parent–offspring conflict (POC) is an expression coined in 1974 by Robert Trivers. It is used to describe the evolutionary conflict arising from differences in optimal parental investment (PI) in an offspring from the standpoint of the parent and the offspring. PI is any investment by the parent in an individual offspring that decreases the parent's ability to invest in other offspring, while the selected offspring's chance of surviving increases. POC occurs in sexually reproducing species and is based on a genetic conflict: Parents are equally related to each of their offspring and are therefore expected to equalize their investment among them. Offspring are only half or less related to their siblings (and fully related to themselves), so they try to get more PI than the parents intended to provide even at their siblings' disadvantage. However, POC is limited by the close genetic relationship between parent and offspring: If an offspring obtains additional PI at the expense of ...

Robert Trivers
Robert Ludlow "Bob" Trivers (; born February 19, 1943) is an American evolutionary biologist and sociobiologist. Trivers proposed the theories of reciprocal altruism (1971), parental investment (1972), facultative sex ratio determination (1973), and parent–offspring conflict (1974). He has also contributed by explaining self-deception as an adaptive evolutionary strategy (first described in 1976) and discussing intragenomic conflict. Education Trivers studied evolutionary theory with Ernst Mayr and William Drury at Harvard from 1968 to 1972, when he earned his PhD in biology. At Harvard he published a series of some of the most influential and highly cited papers in evolutionary biology. His first major paper as a graduate student was "The evolution of reciprocal altruism", published in 1971. In this paper Trivers offers a solution to the longstanding problem of cooperation among unrelated individuals and by doing so overcame a crucial problem for how to police the system by ...
