Psyche Cattell

Psyche Cattell was born to James McKeen Cattell and Josephine Owen Cattell in Garrison, New York on August 2, 1893.[1][7] Her father was a famous psychologist and professor at universities such as University of Pennsylvania and Columbia University.

James Cattell had a large influence on Psyche as he was very involved in his children's education. As a professor, James Cattell had many resources to provide his children with high quality education. Cattell and her siblings were homeschooled by their father and other educators and tutors.[8] Cattell often fell behind her siblings throughout their education, likely due to dyslexia although she was never formally diagnosed. Due to her academic struggles, her father did not support her attending college. As a result, she became a research assistant in order to save up money for college.[3]

Education played a large role in Cattell's life, starting from an early age through her father. When she earned enough tuition money, she attended Barnard College from 1912 to 1914 and Sargent School of Physical Education from 1913 to 1917, and later attended Cornell University.[1] Her and her sister did not receive formal degrees from these institutions due to not have a high school diploma.[1] In 1925, she received a Master of Arts degree from Cornell and a Master of Education degree from Harvard University.[3][9] She went on to receive a Doctor of Education degree from Harvard in 1927.[9] She became the first woman to receive a Doctor of Education from the Harvard Graduate School of Education.

She was a research assistant at Harvard University, starting in 1922, and Stanford University from 1925 to 1926.[3] She remained a research assistant at Harvard until 1936.[3][7] Her time at Harvard is what led her to further research on methods of testing infants' IQs. She went to California to work with Lewis Terman on the Stanford Achievement Test and the development of a masculinity-femininity test.

After her work at Stanford, she returned to Harvard in 1927. While working as a research assistant at Harvard she participated in and assisted with many tests regarding intelligence in children. While a research assistant, she discovered that many of these mental tests could be improved, as they pertained more to school aged children than to infants. By 1932, she was named a research fellow at Harvard and began developing a new testing method, which resulted in the Cattell Infant Intelligence Scale and was published in her book, The Measurement of Intelligence of Infants and Young Children in 1940.[7] She was also an instructor in mental testing for the nursery training school of Boston. Throughout summers she attended many courses at institutions including Woods Hole Marine Biological Laboratory, the Mount Desert Island Biological Laboratory, and the University of Vienna.

Cattell moved to Lancaster, Pennsylvania, where her brother was living, in 1939 to become chief psychologist at the Lancaster Guidance Clinic.[3][1][7] She spent the rest of her life in the area.[1] She was also a psychologist at the Lancaster County Mental Health Clinic from 1939 to 1943.[3] She established a school for young children in her house, known originally as West End Nursery School and West End Nursery School and Kindergarten, in 1941.[7] It became known as The Cattell School, and was formally renamed in 1945.[3][7] She continued to operate it after her 1963 retirement from Lancaster Guidance Clinic until her 80th birthday in 1974.[3][1][7]

She wrote a book, Raising Children with Love and Limits, based on her experiences in 1972.[3][1] She also wrote a column for the local newspaper Lancaster New Era titled "Children Under Eight".[3][1][9]

While working at Harvard, she began performing research for her book, The Measurement of Intelligence of Infants and Young Children, and was led to develop better ways to evaluate brain development in infants. Cattell assisted with many developmental intelligence tests which revolved around the brain development of children and the impact of their environment on it. These tests aimed to examine the ability of children aged from 2–30 months old. She derived this test from the Stanford-Binet scale and the work she did at Harvard.[3] She identified the issue with the available tests at the time, and therefore attempted to implement a new method of testing which worked for younger children. The goal of these tests was to analyze brain development in young children as well as identify the ways in which birth conditions affect the central nervous system.[10] Cattell administered these tests using a variety of toys for each age group tested; each age level had five different items. She created a standardized form of testing early mental ability through these tests, administering 1,346 examinations to 274 children.

The Cattell Infant Intelligence Scale was considered particularly impactful because of its younger age range, short administration time, and easy scoring methods.[10] Cattell implemented significant changes to the test by taking into account the use of objects which may be influenced by home life, and removing them from the test in order to make the test more objective. She published her findings in her book, The Measurement of Intelligence of Infants and Young Children, and sold some kits to perform the scale commercially. The scale is useful because, while it is not able to identify specific problems in a child's development, it may catch that there is a problem early on.

The test primarily assesses motor control and also verbalisation.[11] Later researchers have found that the test is poorly predictive but that "low scores on the scale appear to have greater predictive validity than high scores, particularly when the child has an unfavourable medical history or an impoverished social environment."[12]
