The introduction of Project Spectrum marked a new approach to assessment. Researchers in cognitive and neural sciences provided fresh support for a diverse perspective on cognition. They proposed that the mind is divided into distinct realms of functioning (Gardner, 1993). Gardner defined intelligence as the ability to solve problems and create products that are valued in various cultural settings. According to his theory on multiple intelligences, he suggested that all normal individuals are capable of at least seven "relatively autonomous forms of intellectual accomplishment," each based on a biological potential. He also stated that individuals exhibit a mix of several intelligences. He emphasized that after early infancy, intelligences become embedded in symbol systems such as spoken language and picturing systems.
These systems are notational, such as maps and musical or mathematical notation, as well as fields of knowledge like journalism and mechanical engineering. Gardner pointed out that education represents the cultivation of intelligences over time in culturally fashioned systems. These intelligences are considered biopsychological constructs as they constitute cognitive resources that allow an individual to forge a meaningful connection to a content area. Once the intelligences have been identified, there is a need to assess them. This is the main focus of Project Spectrum. It is "an innovative attempt to measure the profile of intelligences and working styles of young children." The project, a long-term collaborative research effort by several researchers at Harvard Project Zero and David Feldman at Tufts University, focuses on preschool children and aims to detect early individual differences reliably. The project also addresses the predictive value of early identification.
The information gathered from this project can benefit both parents and teachers by providing insights into a child's cognitive competencies, especially during a time when the young child's brain is especially malleable, and schools are likely to be more flexible in their curricula. Initially, the Spectrum Project sought the early indicators of the seven intelligences, but it became apparent that many more competencies warranted examination. Gardner and his colleagues delved into production and perception in music, invented and descriptive narrative in language, and expressive and athletic movement in the bodily-kinesthetic domain.
They also used the notion of adult end states to focus on skills and abilities relevant to achieving significant and rewarding adult roles in society. Instead of concentrating solely on school-related skills, they examined competencies that utilize scientific inventiveness and the child's ability to tell a story or describe an experience.
