Key takeaways

  • Harvey A. Carr belongs to astronomy; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Harvey A. Carr to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Harvey A. Carr from memory before moving on to harder problems.

Reference excerpt

Harvey A. Carr (April 30, 1873 – June 21, 1954), a founding father of functionalist psychology, was renowned for a methodical and thorough approach to his science. His work was largely devoted to studies of animal cognition and perception. Carr collaborated with John B. Watson on his most well-known project: the famous Kerplunk experiment. Carr held his post as chairman of the Psychology department at the University of Chicago from 1926 to 1938. He also served as the president of the American Psychological Association in 1926.

Background

Early life Harvey A. Carr was born in Morris, Illinois, on April 30, 1873, to Hamilton Carr and Bell Garden. He decided that psychology was not the route for him and chose to become a science teacher at the University of Harvard instead. Notably, he was not given the middle initial "A" at birth but instead chose it for himself later in life to round out his signature. Carr was a tall, slim man with a quick wit and a reserved, humble presence. His parents were free-thinkers who encouraged their son to make his own decisions about religion, education, and career. Carr states in his autobiography that the local community "firmly believed in the value of book learning—in so far as its acquisition did not interfere with the serious pursuits of life." With a thirst for knowledge even in these early years, Carr supplemented the teachings provided in his high school and taught himself physics, algebra, and chemistry from textbooks. Though college education was not typical or expected in the community, Carr was driven to learn more. At the age of 18, Carr became a student of DePauw University's preparatory department. He was able to complete a three-year course in two years by taking extra classes and performing extra work in a district school. Carr entered college after completing prep school, and chose to remain at DePauw. Though he had not yet developed specific vocational goals, he felt that the opportunity to learn and sample several subjects was a valuable privilege. Carr opted to major in mathematics, which he found stimulating and absorbing. As his later research in psychology is marked by precision and objectivity, it is perhaps unsurprising that he was taken with mathematics in his early college days. Carr himself admits that this passion likely influenced his approach. He continued in this pursuit until he began to study differential equations; the difficulty of the subject made him doubt his mathematical prowess. Carr took up the study of history, which developed into a lifelong interest. He considered both physics and biology while seeking a new major, though both subjects were poorly supported by the university and the latter was considered to be taboo by the "authorities." The nature of biological study and basis in evolutionary theory were frowned upon in the distinctly religious university. Carr felt repressed by DePauw's religious stance against evolution, and became distrustful of those who would oppose scientific study. Still, he made respectable grades in all of his various subjects and had little concern about his future vocation. At this time, he considered a possible future in law, and decided that it would be best to work and save up prior to attending law school. However, in his third year of college, a serious illness and financial pressures forced him to take leave and Carr returned home to recover for the rest of the year. The following year he spent working the farm and building back up his physical strength. Around this time, farmers in the area suffered some hardships, and Carr took up a job teaching in a country school close by in order to afford to return to school. He was familiar to the people of this area, and respected for his college education. The admiration motivated him to take his teaching duties seriously in order to fulfill the community's expectations of him. Carr had no prior education in educating, and quickly learned that the task required serious skill and experimentation in technique. He cited McMurray's Method of the Recitation as one of his main resources in learning this craft, which heavily impacted his later mentorship of his own graduate students. He found he enjoyed this work and taught with charisma and care in order to get the best from his students. When Carr was ready to return to his own scholarship, he decided to opt for a change of scenery and chose to attend the University of Colorado in 1899. With his bachelor's degree completed, he decided to stay and pursued a Master's. The relocation was just what he needed, and the university provided him with fresh ideas and stimulation. At this time, he intended to try once again to major in mathematics. He felt discouraged by the instructor's unfavorable personality, however, and Carr felt compelled to study instead under another professor with whom he had made a connection. This professor taught Psychology and Education, and Carr identified similarities between these subjects and his own background and interests in teaching. Of psychology, Carr admittedly knew little. He decided to take a minor in history, and relished the opportunity to develop scientific skill in this field. In his words, "Perhaps science must be defined in terms of its spirit and method and not on the basis of the subject matter."

Worked examples

Example 1 — a first encounter with Harvey A. Carr

Start with the simplest possible case. Write down what Harvey A. Carr claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Harvey A. Carr before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Harvey A. Carr ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Harvey A. Carr

In research
Harvey A. Carr appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Harvey A. Carr in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Harvey A. Carr is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1873 births, 1954 deaths, Animal cognition writers, so understanding it makes those chapters shorter.
In everyday life
Look for Harvey A. Carr outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
