Jerome Kagan, professor of Developmental Psychology, said yesterday that his research on cognitive development among children in Roxbury would be discontinued as demanded by a committee of black scholars set up last summer to evaluate and review research in the ghetto.

Kagan said he notified the committee last week that his original research program would be modified to eliminatetheir objections, but added that he did not yet know precisely what form the future research would take.

The Community Research Review Committee (CRRC), an outgrowth of the Black United Front, originally rejected Kagan's project on Oct. 30 and decided during a Dec. 2 meeting to campaign publicly against the research.

Jane Morrison, coordinator of the committee, said that the project was rejected because of the national implications it might have in determining guidelines for future government-funded educational programs.

Richard Kearsley, pediatrician and psychologist, was working with Kagan on the project.

Kagan said he supports the idea "of a committee elected by the community to take some responsibility for monitoring research in the ghetto."

Kagan said he did not know whether the National Institute of Health, which funded his original plan, would insist on reviewing his modified program before releasing those funds.
