mental "organs" ; in a computational metaphor, these
may be construed as separate information-processing devices . Although
all humans exhibit the range of intelligences, individuals differ--presumably for both hereditary and environmental reasons--in their current profile of intelligences.
Moreover, there is no necessary correlation between any two intelligences, and they may indeed entail quite distinct forms of perception, memory, and other psychological processes. Although few occupations rely entirely on a single intelligence, different roles typify the "end states" of each intelligence. For example, the "linguistic" sensitivity to the sounds and construction of language is exemplified by the poet, whereas the interpersonal ability to discern and respond to the moods and motivations of other people is represented in the therapist. Other occupations more clearly illustrate the
need for a blend of intelligences. For instance, surgeons require both the acuity of spatial intelligence to guide the scalpel and the dexterity of the bodily/kinesthetic intelligence to handle it. Similarly, scientists often have to depend on their linguistic intelligence to describe and explain the discoveries made using their logical-mathematic intelligence, and they must employ interpersonal intelligence in interacting with colleagues and in maintaining a productive and smoothly functioning laboratory. The Education and Assessment of Intelligences Until this point, we have been reviewing the history of intelligence research,
admittedly from the perspective of the Theory of Multiple Intelligences (hereafter MI
Theory). Since the publication of Frames of Mind , they and their
colleagues have been involved in investigating its implications. On the one hand, we seek to determine the scientific adequacy of the theory . On the other hand, in their view, a principal value of the multiple intelligence perspectivebe it a theory or a "mere" frameworklies in its potential
contributions to educational reform. In both cases, progress seems to revolve around assessment.
To demonstrate that the intelligences are relatively independent of
one another and that individuals have distinct profiles of intelligences, assessments of each intelligence have to be developed. To take advantage of students' multiple intelligences, there must be some way to identify their strengths and weaknesses reliably. Yet MI Theory grows out of a conviction that standardized tests, with their almost xclusive stress on linguistic and logical skills, are limited. As a result, the further development of MI Theory requires a fresh approach to assessment, an approach consistent with the view that there are a number of intelligences that are developedand can best be detectedin culturally meaningful activities . In the remainder of the paper, the scholars describe their approach to assessment and broadly survey
their efforts to assess individual intelligences at different age levels. In addition, they report some preliminary findings from one of their projects and their implications for the confirmation (or disconfirmation) of MI Theory. If, as argued, each intelligence displays a characteristic set of psychological processes, it is important that these processes be assessed in an "intelligence-fair" manner. In contrast to traditional paper-and-pencil tests, with their inherent bias toward linguistic and logical skills, intelligence-fair measures seek to respect the different modes of
thinking and performance that distinguish each intelligence. Although spatial problems can be approached to some degree through linguistic media (like verbal directions or word problems), intelligence-fair methods place a premium on the abilities to perceive and manipulate visual-spatial information in a direct manner. For example, the spatial intelligence of children can be assessed through a mechanical
activity in which they are asked to take apart and reassemble a meat grinder. The activity requires them to "puzzle out" the structure of the object and then to discern or remember the spatial information that will allow reassembly of the pieces. Although linguistically inclined children may produce a running report about the actions they
are taking, little verbal skill is necessary (or helpful) for successful performance on such a task. Whereas most standard approaches treat intelligence in isolation from the activities of a particular culture, MI theory takes a sharply contrasting tack. Intelligences are always conceptualized and assessed in terms of their cultural manifestation in specific domains of endeavor and with reference to particular adult "end states." Thus, even at
the preschool level, language capacity is not assessed in terms of vocabulary, definitions, or similarities, but rather as manifest in story telling (the novelist) and reporting (the journalist). Instead of attempting to assess spatial skills in isolation, we observe children as they are drawing (the artist) or taking apart and putting together
objects (the mechanic). Ideally, one might wish.to assess an intelligence in a culture-independent way, but this goal has proved to be elusive and perhaps impossible to achieve. Cross-cultural research and studies of cognition in the course of ordinary activities have demonstrated that performances are inevitably
dependent on a person's familiarity and experience with the materials and demands of the assessments. In our own work, it rapidly became clear that meaningful assessment of an intelligence was not possible if students
