HAVELOCK ELLIS English Physician and writer 1859 1939 his works consisted largely of personal accounts of unusual forms of sexual expression he had a fascination of female urination He maintained an extensive correspondence with individuals in numerous countries with the aim of learning about their sexual activities and problems SIGMUND FREUD 18561939 was an Austrian neurologist and the founder of psychoanalysis a school of thought that placed the origin of sexual problems in the operations of the unconscious mind especially during childhood Because psychoanalytic treatment required consultations between patient and analyst that might go on for years Freud created a means by which sexologists could earn a living His theoretical approach contrasted with that of GERMAN PHYSICIAN AND GAY RIGHTS PIONEER MAGNUS HIRSCHFELD who promoted biological ideas about sexuality especially homosexuality best known american sex researcher was ALFRED KINSEY of Indiana University 18941956 he was a trained zoologist and his colleagues undertook large scale sex surveys in the US He published the results of these surveys in two lengthy volumes SEXUAL BEHAVIOR IN THE HUMAN MALE 1948 and SEXUAL BEHAVIOR IN THE HUMAN FEMALE 1953 more than anyone else KINSEY HELPED MAKE SEXUAL BEHAVIOR AN APPROPRIATE TOPIC FOR OBJECTIVE RESEARCH KINSEY was a biologist by profession He made a course of marriage that involved the study of sex he was a professor at the univesity BRONISLAW MALINOWSKI AND MARGARET MEAD were cultural ANTHROPOLOGISTS who investigated non western tribal cultures perspectives on sex BRONISLAW MALINOWSKI spent several years on the Trobriand Islands off the coast of New Guinea and he found that the islanders held a belief that was exactly opposite to that of Aristotle They considered that only the mother contributed to the making of the fetus THIS BELIEF was the foundation of a MATRILINEAL society in which kinship and descent were reckoned only though the female line 0 sexual matters lay at the center of the islanders culture and were freely discussed MARGARET MEAD 19011978 In her 1928 best seller COMING OF THE AGE SAMOA she described how it was a point of pride among teenage Samoan girls to have as many lovers as possible These exploits left them well adjusted and prepared for successful married lives SIGMUND FREUD his conception was unconscious mind was more broadly focused in its sexual desires than was the conscious mind this was particularly true during early childhood which he believed included autoerotic and homosexual phases as well as incestuous desires directed toward one or the other parent FREUD THOUGHT THE quotNORMALquot progression to adult heterosexuality could be derailed in ways such as unconscious emotional processes such as hostile tooOclose orjealous relationships with a parent of sibling These phenomena could lead to what Freud called PERVERSIONS mental states in which adult sexual desires were directed towards atypical targets such as people of the same sex inanimate objects FETISHISM and so on NEUROSES in which the sexual element was supposedly repressed from consciousness altogether and reemerged in the form of nonsexual traits and disorders such as obsessive compulsive behavior depression or quothysteriaquot FREUD TRIED TO UNDERSTAND THE MIND IN TERMS OF PROCESSES THAT THOUGH HIDDEN WERE INHERENTLY MENTALUNCONSCIOUS THOUGHTS and he believed INTERPERSONAL RELATIONSHIPS held the key to sexual orientation and other aspects of adult sexuality MAGNUS HIRSCHFELD proposed the existence of two neural centeral in the brain that were responsible for sexual attraction to men and women respectively He suggested during early fetal life all humans possessed both centers but later one center grew and dominated while the other one regressed Hirschfeld believed that sex hormones channeled development in one direction or another and that people also had a genetic predisposition to same sex or opposite sex attraction FREUD AND HIRSCHFELD represented opposite approaches to understanding the mind and sexuality HIRSCHFELD TRIED TO REDUCE THE MIND TO RELATIVELY SIMPLE NONMENTAL PHENOMENA SUCH AS THE GROWTH AND ACTIVITY OF NERVE CELLS HORMONE SECRETION AND INFO ENCODED IN THE GENES These phenomena controlled sexual development in a manner that was largely independent to family relationships and other aspects of life experience birth control was illegal until the 60s FEMINISTS CAMPAIGNED FOR SEXUAL REFORMS book notes The American gynecologist WILLIAM MASTERS 1915 2001 and his research assistant later wife VIRGINIA JOHNSON 1925 recruited volunteers to engage in sexual behavior in their laboratory during the late 1950s they studied their volunteers39 sexual responses not only by visual observation but also by means of recording instruments they published their observations in a 1966 book HUMAN SEXUAL RESPONSE this book was the rst comprehensive description of how men39s and women39s bodies perform during sexual behavior they also studied men and women who suffered from a variety of sexual problems and they developed techniques for helping such people improve their sex lives this was in their book HUMAN SEXUAL INADEOUACY 1970 FEMINISM the belief that women are entitled to the same social economic and political rights as men MARGARET SANGER 18791966 campaigned tirelessly for women39s right to learn about and use contraceptives she spent a month in jail at one point She and her colleagues opened birth control clinics and helped develop new

conservative stepby step More data more reliability SCIENTIFIC METHOD Observations things we see hear smell taste or touch may lead to question Question Ask a question then scientist will make a hypothesis which is an answer to this question they came up with Hypothesis Not necessarily correct It s the working solution scientists will use for testing Prediction Done for prep for testing If I do x then y will happen It is made by the hypothesis Test Experimental or additional observation 0 Test does not support hypothesis revise hypothesis or pose a new one 0 Test supports make additional predictions and test them Anytime we test a hypothesis in an experiment we will have VARIABLES Independent variables IV the thing we are changing manipulating Dependent variables DV what changes as a result ofthat Sex Research IV THE STIMULUS THAT THE RESEARCHER GAVE DV THE RESPONSE THAT WAS MEASURED Characteristic of a subject or quantity that can change 0 Individual attributes o Magnitude of stimulus provided 0 Nature of individual s response time TYPES OF RESEARCH METHODS Laboratory investigations Longitudinal and crosssectional studies look at how things are diff for people at diff ages Longitudinal will study same woman for a LONG TIME More accurate but is much more expensive Crosssectional if faster Diff people with diff ages are studied at once Surveys questionnaires and interviews Field studies researcher goes out into environment and observe Ex Going to a bar and observing irting habts Correlation Studies looks at relationship between two things MASTERS amp JOHNSON THE PHYSIOLOGY OF SEXUAL RESPONSE 1954 participants engaged in sexual behavior in the laboratory They followed heart rates muscles etc Instruments such as electromyographs were used to take measurements Data collection techniques included practice sessions to get them comfortable so when measurement taken then the actions would be natural LIMITATIONS of the scienti c method in the study of human sexuality Reliability and accuracy of the data inthelab PROBLEM OF REFUSAL OR NONRESPONSE people refuse to participate VOLUNTEER BIAS may occur when the researcher studies people who agree to be in the research More issues RELIABILITY OF SELFREPORTS OF SEXUAL BEHAVIOR PURPOSEFUL DISTORTION intentionally giving self reports that are distortions of reality MEMORY it is difficult to remember facts accurately DIFFICULTIES WITH ESTIMATES it is dif cult to estimate time especially when engaged in sex SELF REPORTS vs DIREC T OBSERVATIONS DIRECT OBSERVATION are accurate no purposeful distortion or inaccurate memory can occur PROBLEMS expensive timeconsuming and sexual behavior in the laboratory might be inhibited There is always going to be some kind of error EXTRANEOUS FACTORS

response FREQUENCY how often a person does something CORRELATIONAL METHODS A CORRELATION is a number that measures the relationship between 2 variables How are these things related Just because they correlate does not mean one caused the other DO NOT indicate cause and effect relationships Explore relationships between two variables RESEARCH HAS HAD A PRACTICAL IMPACT ON PEOPLE S SEX LIVES the discovery of sex hormones led to the development of oral contraceptives and treatment for breast and prostate cancer advances in reproductive physiology led to the development of vitro fertilization
