Psyche Cattell (August 2, 1893-April 1989) was an American psychologist who studied cognitive development in children.
She was Chief Psychologist at Lancaster Guidance Clinic in Lancaster, Pennsylvania from 1939-1963.
She published a book on intelligence testing and established a nursery school in her home which operated from 1941 to 1974.
She is best known for the Cattell Infant Intelligence Scale, a downward extension of IQ testing used to assess children's development.
It primarily assesses motor control and also verbalisation.
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." She wrote a book, Raising Children with Love and Limits, based on her experiences in 1972.She began her education at Sargent School of Physical Education, and later attended Cornell University and obtained her master's degree, and later Harvard University for her Master of Education degree and her Doctorate in Education.
Cattell also served as an instructor mental testing for the nursery training school of Boston.
During this time, 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.
She made significant improvements to the Stanford-Binet scale, an intelligence scale for young children, to form the Cattell Infant Intelligence scale, a scale which is still used today.
Cattell never married, however she adopted two children, which at the time, was incredibly rare.
