The term preferences is used in a variety of related, but not identical, ways in the scientific literature. This makes it necessary to make explicit the sense in which the term is used in different social sciences.

In psychology, preferences could be conceived of as an individual’s attitude towards a set of objects, typically reflected in an explicit decision-making process (Lichtenstein & Slovic, 2006). Alternatively, one could interpret the term “preference” to mean evaluative judgment in the sense of liking or disliking an object (e.g., Scherer, 2005) which is the most typical definition employed in psychology. However, it does not mean that a preference is necessarily stable over time. Preference can be notably modified by decision-making processes, such as choices (Brehm, 1956; Sharot, De Martino, & Dolan, 2009), even in an unconscious way (see Coppin, Delplanque, Cayeux, Porcherot, & Sander, 2010).

"Preference" may also refer to non-choices, such as genetic and biological explanations for one's preference. Sexual orientation, for example, is no longer considered a sexual preference by most individuals, but is debatable based on philosophical and/or scientific ideas.

Julien Clerc, pronounced: [ʒy.ljɛ̃ klɛʁ], born as Paul Alain Leclerc on 4 October 1947 in Paris, Clerc's parents divorced when he was still young. He grew up listening to classical music in his father's home, while his mother introduced him to the music of such singers as Georges Brassens and Edith Piaf. He began to learn the piano at six, and by 13, started to play by ear everything he heard on the radio.

During his high school and university days, he met Maurice Vallet and Etienne Roda-Gil, two of his main songwriters, and began to compose his first songs. He changed his name to Julien Clerc upon signing a contract with Pathé Marconi, releasing his first album in May 1968.

Clerc's famous vibrato voice and neosymphonic music, coupled with the almost dreamlike lyrics written by Vallet and Roda-Gil, fitted in with that period of change. The album went on to win the Charles Cros Academy Record Award. In 1969, Clerc went on the Olympia stage for the first time to open for Gilbert Becaud's concert. Despite having been in show business for only one year, his performance was a great success. He would later return repeatedly to the Olympia for a series of concerts.

Coco Rocha (born Mikhaila Rocha on September 10, 1988) is a Canadian fashion model.

Rocha was born in Toronto, Ontario, and grew up in Richmond, British Columbia where she attended McRoberts Secondary School. Her family is in the airline industry. Her mother, Juanita, is a flight attendant and her father, Trevor Haines, is a ticket manager. She has one step sister named Lynsey. She is of Irish, Russian, and Welsh descent.

Rocha is one of the few models who has spoken out against the prevalence of eating disorders in the modelling industry. In an open letter to the New York Times, Coco spoke out on her blog about the pressure the fashion industry puts on young models "How can any person justify an aesthetic that reduces a woman or child to an emaciated skeleton? Is it art? Surely fashion’s aesthetic should enhance and beautify the human form, not destroy it." [1] In an email to the Associated Press, she gives an insight into the fashion world, saying: "I'll never forget the piece of advice I got from people in the industry when they saw my new body ... They said, 'You need to lose more weight. The look this year is anorexia. We don't want you to be anorexic but that's what we want you to look like.

Son Ye-jin (born Son Yeon-jin on January 11, 1982) is a South Korean actress.

Son Ye-jin has taken on a variety of roles in her career to date, propelling her to fame both in Korea and in other Asian countries. She first appeared in a supporting role in Park Ki-hyung's film Secret Tears in 2000, and then went on to take the lead in TV dramas such as Delicious Proposal, Sun-hee and Jin-hee, and Daemang: Great Ambition. Her first high-profile role in cinema was in Im Kwon-taek's Chi-hwa-seon, which screened at Cannes and took home a Best Director award in 2002.

The biggest success of her early career was in the subsequent films Lovers' Concerto and The Classic. Both were solid mid-level hits in Korea, and The Classic in particular—being a work of My Sassy Girl director Kwak Jae-yong -- received wide exposure in countries such as Hong Kong and China.

Son further solidified her status as a "hallyu" (Korean wave) star in 2003 by taking the lead in TV drama Summer Scent, a part of the hugely successful series of TV dramas including Autumn Love Story and Winter Sonata (though this drama would not attract the attention of the previous two). Her next two films also proved to be huge hits in Asia: A Moment to Remember, based on a famous Japanese TV series, set box office records in Japan and sold over two million tickets in Korea, while April Snow in which she co-starred with superstar Bae Yong-joon was also a smash hit in Japan and China (though not, incidentally, in Korea).
