Gustav Theodor Fechner (1801–1887)

Psychophysics , study of quantitative relations between psychological events and physical events or, more specifically, between sensations and the stimuli that produce them. Physical science permits, at least for some of the senses , accurate measurement on a physical scale of the magnitude of a stimulus. By determining the stimulus magnitude that is just sufficient to produce a sensation or a response , it is possible to specify the minimum perceptible stimulus, or the absolute stimulus threshold stimulus limen , for the various senses. The central inquiry of psychophysics pertains to the search for a lawful, quantitative relation between stimulus and sensation for the range of stimuli between these limits. Psychophysics was established by German scientist and philosopher Gustav Theodor Fechner. He coined the word, developed the fundamental methods, conducted elaborate psychophysical experiments, and began a line of investigation that still persists in experimental psychology. Trained in physics , Fechner in his later life became interested in metaphysics and searched for a way of relating the spiritual to the physical world.

Ernst Mach February 18, — February 19, made major contributions to physics, philosophy, and physiological psychology. In physics, the speed of sound bears his name, as he was the first to systematically study super-sonic motion. He also made important contributions to understanding the Doppler effect. His critique of Newtonian ideas of absolute space and time were an inspiration to the young Einstein, who credited Mach as being the philosophical forerunner of relativity theory. His systematic skepticism of the old physics was similarly important to a generation of young German physicists.

We are all fascinated by physiognomy, intrigued by the appearance of the people we admire. These perceptual portraits of more than thinkers who have fashioned our understanding of mind and behavior provide an alternative view of the history of psychology that is both pleasing and puzzling. The portraits and motifs have been manipulated in a variety of ways, using graphic and photographic procedures. They are arranged in order of birth date in a format of one page of descriptive text facing a full-page perceptual portrait. The text presents a brief synopsis of the person portrayed, that person's ideas, and the source of both the portrait and the motif.

Sigmund Freud — founder of psychoanalysis. In psychoanalysis, the precept according to which psychological processes and actions are governed by the gratification of needs and the avoidance or discharge of unpleasurable tension. It is the governing principle of the id, in contrast to the reality principle, which is a governing principle of the ego. Freud introduced the concept in his book The Interpretation of Dreams , where he initially called it the unpleasure principle Standard Edition, IV-V, at p. Also called the pleasure-pain principle or awkwardly but closer to Freud's original German the pleasure-unpleasure principle.

Who is considered the father of psychology? This question does not necessarily have a cut-and-dry answer since many individuals have contributed to the inception, rise, and evolution of modern-day psychology. We'll take a closer look at a single individual who is most often cited as well as other individuals who are also considered fathers of various branches of psychology. Wilhelm Wundt is the man most commonly identified as the father of psychology. Other people such as Hermann von Helmholtz, Gustav Fechner, and Ernst Weber were involved in early scientific psychology research , so why are they not credited as the father of psychology?

Wilhelm Wundt Biography

Look at any introductory psychology book that covers psychoanalysis, and you are likely to find an image of an iceberg floating in the sea. The image serves as an illustrative metaphor for Freud's theory of the mind: Only a fragment of our ideas and feelings are conscious or "visible" to us, while the vast bulk of our mental content is unconscious or "invisible" to everyday introspection. A simple Internet search of the terms "Freud iceberg" will bring forth hundreds of examples.

An early pioneer in experimental psychology and founder of psychophysics , he inspired many 20th-century scientists and philosophers. Despite being raised by his religious father, Fechner became an atheist in later life. In he was appointed professor of physics at Leipzig. But in , he contracted an eye disorder while studying the phenomena of color and vision , and, after much suffering, resigned.

Единственное, что он понял из его сбивчивого рассказа, - это что перед смертью Танкадо отдал кольцо. - Танкадо отдал кольцо? - скептически отозвалась Сьюзан. - Да.

 Каковы ваши рекомендации? - требовательно спросил Фонтейн.  - Что вы предлагаете. - Рекомендации? - выпалил Джабба.

У всех терминалов были совершенно одинаковые клавиатуры. Как-то вечером Хейл захватил свою клавиатуру домой и вставил в нее чип, регистрирующий все удары по клавишам. На следующее утро, придя пораньше, он подменил чужую клавиатуру на свою, модифицированную, а в конце дня вновь поменял их местами и просмотрел информацию, записанную чипом. И хотя в обычных обстоятельствах пришлось бы проверять миллионы вариантов, обнаружить личный код оказалось довольно просто: приступая к работе, криптограф первым делом вводил пароль, отпирающий терминал.

Конечно, Джабба прав. Поскольку числовая строка бесконечна, всегда можно заглянуть дальше и найти еще одно простое число. Между 0 и 1 000 000 более 70 000 вариантов.

Через каждые несколько шагов Стратмор останавливался, держа пистолет наготове, и прислушивался. Единственным звуком, достигавшим его ушей, был едва уловимый гул, шедший снизу. Сьюзан хотелось потянуть шефа назад, в безопасность его кабинета.

На него сверху вниз смотрел прыщавый бритоголовый коротышка. Половина головы красная, половина - синяя. Как пасхальное яйцо.

 Договорились, - сказал Беккер и поставил бутылку на стол. Панк наконец позволил себе улыбнуться. - Заметано.
