Sexual Jealousy In Humans
Sexual jealousy is a special form of jealousy in sexual relationships, based on suspected or imminent sexual infidelity. The concept is studied in the field of evolutionary psychology. Basis Evolutionary psychologists have suggested that there is a gender difference in sexual jealousy, driven by men and women's different reproductive biology. The theory proposes that a man perceives a threat to his relationship's future because he could be fooled into raising children that are not his own. In contrast, a woman risks losing to another the relationship and all the benefits that entails. Research has shown that men are impacted more by sexual infidelity, while women are more impacted by emotional infidelity. An alternative explanation is from a ''social-cognitive perspective''. Typically, men place importance on their masculinity and sexual dominance. When the male's partner commits sexual infidelity, these two components of his ego become severely threatened. Women are more emot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Uxoricide
Uxoricide (from Latin ''uxor'' meaning "wife" and -cide, from ''caedere'' meaning "to cut, to kill") is the killing of one's own wife. It can refer to the act itself or the person who carries it out. It can also be used in the context of the killing of one's own girlfriend. The killing of a husband is called mariticide. Rates of uxoricide Though overall rates of spousal violence and homicide in the US have declined since the 1970s, rates of uxoricide are significantly higher than rates of mariticide (the murder of a husband). Of the 2340 deaths at the hands of intimate partners in the US in 2007, female victims made up 70%. FBI data from the mid-1970s to mid-1980s found that for every 100 husbands who killed their wives in the United States, about 75 women killed their husbands. However, wives were more likely to kill their husbands than vice versa in some US cities including Chicago, Detroit, Houston, and St. Louis. Uxoricide rates varied among different demographic subgroup ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fertility
Fertility is the capability to produce offspring through reproduction following the onset of sexual maturity. The fertility rate is the average number of children born by a female during her lifetime and is quantified demographically. Fertility is addressed when there is a difficulty or an inability to reproduce naturally, which is referred to as infertility. Infertility is widespread, with fertility specialists available all over the world to assist mothers and couples who experience difficulties having a baby. Human fertility depends on factors of nutrition, sexual behaviour, consanguinity, culture, instinct, endocrinology, timing, economics, personality, way of life, and emotions. Fertility differs from fecundity, which is defined as the ''potential'' for reproduction (influenced by gamete production, fertilization and carrying a pregnancy to term). Where a woman or the lack of fertility is infertility while a lack of fecundity would be called sterility. Demography I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mate Value
Mate value is derived from Charles Darwin's theory of evolution and sexual selection, as well as the social exchange theory of relationships. Mate value is defined as the sum of traits that are perceived as desirable, representing genetic quality and/or fitness (biology), an indication of a potential mate's reproductive success. Based on mate desirability and mate preference, mate value underpins mate selection and the formation of romantic relationships. Mate value can predict availability of mates, for example, a higher mate value means one is desirable to more individuals and so can afford to be more choosy in mate selection. Thus, one's own mate value can influence trait and mate preferences, it has been shown that an individual will show preference for another who has a similar mate value, to avoid rejection. Specifically, one could infer that one's own mate value has a direct impact upon partner choice through the biological market theory. Here, it is believed that 'high-marke ...

Genetics
Genetics is the study of genes, genetic variation, and heredity in organisms.Hartl D, Jones E (2005) It is an important branch in biology because heredity is vital to organisms' evolution. Gregor Mendel, a Moravian Augustinian friar working in the 19th century in Brno, was the first to study genetics scientifically. Mendel studied "trait inheritance", patterns in the way traits are handed down from parents to offspring over time. He observed that organisms (pea plants) inherit traits by way of discrete "units of inheritance". This term, still used today, is a somewhat ambiguous definition of what is referred to as a gene. Trait inheritance and molecular inheritance mechanisms of genes are still primary principles of genetics in the 21st century, but modern genetics has expanded to study the function and behavior of genes. Gene structure and function, variation, and distribution are studied within the context of the cell, the organism (e.g. dominance), and within the ...

Libido
Libido (; colloquial: sex drive) is a person's overall sexual drive or desire for sexual activity. Libido is influenced by biological, psychological, and social factors. Biologically, the sex hormones and associated neurotransmitters that act upon the nucleus accumbens (primarily testosterone and dopamine, respectively) regulate libido in humans. Social factors, such as work and family, and internal psychological factors, such as personality and stress, can affect libido. Libido can also be affected by medical conditions, medications, lifestyle and relationship issues, and age (e.g., puberty). A person who has extremely frequent sexual urges, or a suddenly increased sex drive may be experiencing hypersexuality, while the opposite condition is hyposexuality. In psychoanalytic theory, libido is psychic drive or energy, particularly associated with sexual instinct, but also present in other instinctive desires and drives. A person may have a desire for sex, but not have the opportu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Attachment Theory
Attachment theory is a psychological, evolutionary and ethological theory concerning relationships between humans. The most important tenet is that young children need to develop a relationship with at least one primary caregiver for normal social and emotional development. The theory was formulated by psychiatrist and psychoanalyst John Bowlby. Within attachment theory, infant behaviour associated with attachment is primarily the seeking of proximity to an attachment figure in stressful situations. Infants become attached to adults who are sensitive and responsive in social interactions with them, and who remain as consistent caregivers for some months during the period from about six months to two years of age. During the latter part of this period, children begin to use attachment figures (familiar people) as a secure base to explore from and return to. Parental responses lead to the development of patterns of attachment; these, in turn, lead to internal working models ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Violence
Violence is the use of physical force so as to injure, abuse, damage, or destroy. Other definitions are also used, such as the World Health Organization's definition of violence as "the intentional use of physical force or Power (social and political), power, threatened or actual, against oneself, another person, or against a group or community, which either results in or has a high likelihood of resulting in injury, death, psychological harm, maldevelopment, or deprivation."Krug et al."World report on violence and health", World Health Organization, 2002. Internationally, violence resulted in deaths of an estimated 1.28 million people in 2013 up from 1.13 million in 1990. However, global population grew by roughly 1.9 billion during those years, showing a dramatic reduction in violence per capita. Of the deaths in 2013, roughly 842,000 were attributed to self-harm (suicide), 405,000 to interpersonal violence, and 31,000 to collective violence (war) and legal intervention. Fo ...

Social Comparison Theory
Social comparison theory, initially proposed by social psychologist Leon Festinger in 1954, centers on the belief that there is a drive within individuals to gain accurate self-evaluations. The theory explains how individuals evaluate their own opinions and abilities by comparing themselves to others in order to reduce uncertainty in these domains, and learn how to define the self. Comparing oneself to others socially is a form of measurement and self assessment to identify where an individual stands according to their own set of standards and emotions about themselves. Following the initial theory, research began to focus on social comparison as a way of self-enhancement, introducing the concepts of downward and upward comparisons and expanding the motivations of social comparisons.Schachter, S. (1959). The psychology of affiliation: Experimental studies of the sources of gregariousness (Vol. 1). Stanford University Press. Social comparison can be traced back to the pivotal paper ...

Depression (mood)
Depression is a mental state of low mood and aversion to activity, which affects more than 280 million people of all ages (about 3.5% of the global population). Classified medically as a mental and behavioral disorder, the experience of depression affects a person's thoughts, behavior, motivation, feelings, and sense of well-being. The core symptom of depression is said to be anhedonia, which refers to loss of interest or a loss of feeling of pleasure in certain activities that usually bring joy to people. Depressed mood is a symptom of some mood disorders such as major depressive disorder and dysthymia; it is a normal temporary reaction to life events, such as the loss of a loved one; and it is also a symptom of some physical diseases and a side effect of some drugs and medical treatments. It may feature sadness, difficulty in thinking and concentration and a significant increase or decrease in appetite and time spent sleeping. People experiencing depression may have ...

Domestic Violence
Domestic violence (also known as domestic abuse or family violence) is violence or other abuse that occurs in a domestic setting, such as in a marriage or cohabitation. ''Domestic violence'' is often used as a synonym for ''intimate partner violence'', which is committed by one of the people in an intimate relationship against the other person, and can take place in relationships or between former spouses or partners. In its broadest sense, domestic violence also involves violence against children, parents, or the elderly. It can assume multiple forms, including physical, verbal, emotional, economic, religious, reproductive, or sexual abuse. It can range from subtle, coercive forms to marital rape and other violent physical abuse, such as choking, beating, female genital mutilation, and acid throwing that may result in disfigurement or death, and includes the use of technology to harass, control, monitor, stalk or hack. Domestic murder includes stoning, bride burning, ho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Disgust
Disgust (Middle French: ''desgouster'', from Latin ''gustus'', "taste") is an emotional response of rejection or revulsion to something potentially contagious or something considered offensive, distasteful, or unpleasant. In ''The Expression of the Emotions in Man and Animals'', Charles Darwin wrote that disgust is a sensation that refers to something revolting. Disgust is experienced primarily in relation to the sense of taste (either perceived or imagined), and secondarily to anything which causes a similar feeling by sense of smell, touch, or vision. Musically sensitive people may even be disgusted by the cacophony of inharmonious sounds. Research has continually proven a relationship between disgust and anxiety disorders such as arachnophobia, blood-injection-injury type phobias, and contamination fear related obsessive–compulsive disorder (also known as OCD). Disgust is one of the basic emotions of Robert Plutchik's theory of emotions, and has been studied extensively ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
