Lightner Witmer: biography of this clinical psychologist

Lightner Witmer, formerly David L. Witmer Jr., was born on June 28, 1867 in Philadelphia, United States. The son of David Lightner and Katherine Huchel, and the eldest of four children, Witmer earned a doctorate in psychology and soon developed into a fellowship at the University of Pennsylvania. Likewise, he had training in the arts, in finance and economics, and in political science.

Like other scientists and psychologists of the time, Witmer

grew up in the context of the post-American civil war, around an emotional atmosphere strongly charged with concern and at the same time fears and hopes.

In addition, Witmer was born in Philadelphia, which in the same context had been characterized by different events that marked the history of the country, such as the Battle of Gettysburg and the various struggles for the prohibition of slavery. All of the above led Witmer to develop a special concern for using psychology as a tool for social improvement.

Training and academic career

After having graduated in political science, and intending to continue studying law, Witmer he met the experimental psychologist James McKeen Cattell, who was one of the most influential intellectuals of the time.

This last reason Witmer to start his studies in psychology. Witmer soon became interested in this discipline, partly because he had previously worked as a professor of history and English. with children of different ages, and he had noticed that many of them had various difficulties, for example, distinguishing sounds or letters. Far from standing aside, Witmer had worked closely with these children, and his help had been instrumental in increasing their learning.

After meeting Cattell (who had also trained with another of the fathers of psychology, Wilhelm Wundt) and after agreeing to work as his assistant, Witmer and Cattell founded an experimental laboratory where the main objective was to study the differences in reaction times between different individuals.

Cattell soon leaves the university, and the laboratory, and Witmer begins working as Wundt's assistant at the University of Leipzig in Germany. After earning his Ph.D., Witmer returned to the University of Pennsylvania as director of the psychology laboratory, specializing in research and teaching in child psychology.

America's First Psychology Clinic

As part of his work in the psychology laboratory at the University of Pennsylvania, Witmer he founded the first child care psychologist clinic in the United States.

Among other things, he was in charge of working with different children, with the aim of helping them overcome what he called "defects" for learning and socialization. Witmer maintained that these defects were not diseases, nor were they necessarily the result of a defect in the brain, but rather a mental state of the child's development.

In fact, he said that these children should not be considered as "abnormal", since if they deviated from the average, this was because their development was at an earlier stage than the majority. But with adequate clinical support, supplemented by a training school that functioned like a teaching hospital, their difficulties could be offset.

Witmer and the beginnings of clinical psychology

In the debate about hereditary or environmental determination of behavior, which dominated much of the psychology of the moment, Witmer initially positioned himself as one of the defenders of hereditary factors. However, after beginning interventions as a clinical psychologist, Weimer he maintained that the development and capacities of the child were strongly conditioned by environmental elements and by the socioeconomic role.

From there, his clinic focused on expanding the study of educational psychology and what was previously called special education. Furthermore, he is credited with being the father of clinical psychology because he was the first to use the term "Clinical Psychology" in the year 1896, during a work session of the American Psychological Association (APA).

In the same context, Witmer defended the separation of psychology and philosophy, especially advocated splitting the APA from the American Philosophical Association. Since the latter generated various controversies, Witner and Edward Titchener founded an alternative society only for experimental psychologists.

Witmer strongly defended that the investigations carried out in psychology, in laboratories, as well as the theories that developed by the great intellectuals, could have a practical and direct use to improve the quality of life of the people. Likewise, at the base of the development of clinical psychology is the premise that practice and research are inseparable elements for this discipline.
