Abstract

The present invention provides a method of doing cognitive diagnosis of mental skills, medical and psychiatric diagnosis of diseases and disorders, and in general the diagnosing of latent properties of a set of objects, usually people, for which multiple pieces of binary (dichotomous) information about the objects are available, for example testing examinees using right/wrong scored test questions. Settings where the present invention can be applied but are not limited to include classrooms at all levels, web-based instruction, corporate in-house training, large scale standardized tests, and medical and psychiatric settings. Uses include but are not limited to individual learner feedback, learner remediation, group level educational assessment, and medical and psychiatric treatment.

Claims

1. A computer-implemented method for assessing behavioral characteristics of an individual, the method comprising:

receiving a response from an individual for each of a plurality of items;

determining an item/preference incidence matrix with a computer;

determining a behavioral value for each preference based on the item responses and the item/preference incidence matrix with the computer; and

providing a behavioral profile to the individual based on the behavioral values.

2. The method of claim 1, further comprising:

providing the individual with an instructional module based on a pattern of behavioral values for the individual.

3. The method of claim 2, wherein user instructions are provided to the individual in a subject pertaining to the preference having a smallest behavioral value.

4. The method of claim 2, wherein user instructions are provided to the individual in each subject pertaining to a preference having a behavioral value below a threshold.

5. The method of claim 2, wherein user instructions are provided to the individual in a subject that is selected based on a pattern of behavioral values across all preferences.

6. The method of claim 1, wherein the item/preference incidence matrix includes a ‘

1’

for each entry corresponding to a preference that is required to respond positively to an item, wherein the item/preference incidence matrix includes a ‘

0’

for each entry corresponding to a preference that is not required to respond positively to an item.

7. A computer-implemented system for assessing behavioral characteristics of an individual, said system comprising:

a computer;

wherein the computer is programmed to perform steps comprising;

receiving a response from an individual for each of a plurality of items;

determining an item/preference incidence matrix using a computer;

determining a behavioral value for each preference based on the item responses and the item/preference incidence matrix using a computer; and

providing a behavioral profile to the individual based on the behavioral values.

8. The system of claim 7, wherein the computer is programmed to place the individual in an instructional module based on a pattern of behavioral values for the individual.

9. The system of claim 8, wherein user instructions are provided to the individual in a subject pertaining to the preference having a smallest behavioral value.

10. The system of claim 8, wherein user instructions are provided to the individual in each subject pertaining to a preference having a behavioral value below a threshold.

11. The system of claim 8, wherein user instructions are provided to the individual in a subject that is selected based on a pattern of behavioral values across all preferences.

12. The system of claim 7, wherein the item/preference incidence matrix includes a ‘

1’

for each entry corresponding to a preference that is required to respond positively to an item, wherein the item/preference incidence matrix includes a ‘

0’

for each entry corresponding to a preference that is not required to respond positively to an item.
