Question: Who was the first president of the publisher of Families, Systems and Health?

full_context: Document 1: History of science: The end of the 19th century marks the start of psychology as a scientific enterprise. The year 1879 is commonly seen as the start of psychology as an independent field of study. In that year Wilhelm Wundt founded the first laboratory dedicated exclusively to psychological research (in Leipzig). Other important early contributors to the field include Hermann Ebbinghaus (a pioneer in memory studies), Ivan Pavlov (who discovered classical conditioning), William James, and Sigmund Freud. Freud's influence has been enormous, though more as cultural icon than a force in scientific psychology.

Document 3: Health Psychology (journal): Health Psychology is a monthly, peer-reviewed academic journal published by the American Psychological Association. The journal is "devoted to understanding the scientific relations among psychological factors, behavior and physical health and illness." The current editor-in-chief is Kenneth E. Friedland (Washington University in St. Louis).
Document 4: Adolescence: A broad way of defining adolescence is the transition from child-to-adulthood. According to Hogan & Astone (1986), this transition can include markers such as leaving school, starting a full-time job, leaving the home of origin, getting married, and becoming a parent for the first time. However, the time frame of this transition varies drastically by culture. In some countries, such as the United States, adolescence can last nearly a decade, but in others, the transition—often in the form of a ceremony—can last for only a few days.
Document 5: Psychoanalytic theory: Psychoanalytic theory is the theory of personality organization and the dynamics of personality development that guides psychoanalysis, a clinical method for treating psychopathology. First laid out by Sigmund Freud in the late 19th century, psychoanalytic theory has undergone many refinements since his work. Psychoanalytic theory came to full prominence in the last third of the twentieth century as part of the flow of critical discourse regarding psychological treatments after the 1960s, long after Freud's death in 1939, and its validity is now widely disputed or rejected. Freud had ceased his analysis of the brain and his physiological studies and shifted his focus to the study of the mind and the related psychological attributes making up the mind, and on treatment using free association and the phenomena of transference. His study emphasized the recognition of childhood events that could influence the mental functioning of adults. His examination of the genetic and then the developmental aspects gave the psychoanalytic theory its characteristics. Starting with his publication of The Interpretation of Dreams in 1899, his theories began to gain prominence.

Document 8: Adolescence: The formal study of adolescent psychology began with the publication of G. Stanley Hall's "Adolescence in 1904." Hall, who was the first president of the American Psychological Association, viewed adolescence primarily as a time of internal turmoil and upheaval (sturm und drang). This understanding of youth was based on two then new ways of understanding human behavior: Darwin's evolutionary theory and Freud's psychodynamic theory. He believed that adolescence was a representation of our human ancestors' phylogenetic shift from being primitive to being civilized. Hall's assertions stood relatively uncontested until the 1950s when psychologists such as Erik Erikson and Anna Freud started to formulate their theories about adolescence. Freud believed that the psychological disturbances associated with youth were biologically based and culturally universal while Erikson focused on the dichotomy between identity formation and role fulfillment. Even with their different theories, these three psychologists agreed that adolescence was inherently a time of disturbance and psychological confusion. The less turbulent aspects of adolescence, such as peer relations and cultural influence, were left largely ignored until the 1980s. From the '50s until the '80s, the focus of the field was mainly on describing patterns of behavior as opposed to explaining them.
Document 9: Social psychology: The first published study in this area was an experiment in 1898 by Norman Triplett, on the phenomenon of social facilitation. During the 1930s, many Gestalt psychologists, most notably Kurt Lewin, fled to the United States from Nazi Germany. They were instrumental in developing the field as something separate from the behavioral and psychoanalytic schools that were dominant during that time, and social psychology has always maintained the legacy of their interests in perception and cognition. Attitudes and small group phenomena were the most commonly studied topics in this era.
Document 10: Adolescence: Adolescence (from Latin adolescere, meaning "to grow up") is a transitional stage of physical and psychological human development that generally occurs during the period from puberty to legal adulthood (age of majority). The period of adolescence is most closely associated with the teenage years, though its physical, psychological and cultural expressions may begin earlier and end later. For example, although puberty has been historically associated with the onset of adolescent development, it now typically begins prior to the teenage years and there has been a normative shift of it occurring in preadolescence, particularly in females (see precocious puberty). Physical growth, as distinct from puberty (particularly in males), and cognitive development generally seen in adolescence, can also extend into the early twenties. Thus chronological age provides only a rough marker of adolescence, and scholars have found it difficult to agree upon a precise definition of adolescence.
Document 11: Journal of Personality and Social Psychology: The Journal of Personality and Social Psychology is a monthly peer-reviewed scientific journal published by the American Psychological Association that was established in 1965. It covers the fields of social and personality psychology. The editors-in-chief are Shinobu Kitayama (University of Michigan; "Attitudes and Social Cognition Section"), Kerry Kawakami (York University; "Interpersonal Relations and Group Processes Section"), and M. Lynne Cooper (University of Missouri; "Personality Processes and Individual Differences Section").
Document 12: Adolescence: In 1989, Troiden proposed a four-stage model for the development of homosexual sexual identity. The first stage, known as sensitization, usually starts in childhood, and is marked by the child's becoming aware of same-sex attractions. The second stage, identity confusion, tends to occur a few years later. In this stage, the youth is overwhelmed by feelings of inner turmoil regarding their sexual orientation, and begins to engage sexual experiences with same-sex partners. In the third stage of identity assumption, which usually takes place a few years after the adolescent has left home, adolescents begin to come out to their family and close friends, and assumes a self-definition as gay, lesbian, or bisexual. In the final stage, known as commitment, the young adult adopts their sexual identity as a lifestyle. Therefore, this model estimates that the process of coming out begins in childhood, and continues through the early to mid 20s. This model has been contested, and alternate ideas have been explored in recent years.
