      The Cognitive Interview (CI) is one of the most widely studied and used methods to interview witnesses. However, new component techniques for further increasing correct recall are still crucial. We focused on how a new and simpler interview strategy, Category Clustering Recall (CCR), could increase recall in comparison with witness-compatible questioning and tested if a Revised Cognitive Interview (RCI) with CCR instead of witness-compatible questioning and without the change order and change perspective mnemonics would be effective for this purpose. Participants watched a mock robbery video and were interviewed 48 hours later with either the CI or the RCI. Recalled information was classified as either correct, incorrect or confabulation. Although exclusion of the change order and change perspective mnemonics in the RCI group might have caused a slight decrease in recall during the last interview phases, the RCI group generally produced more correct information than the CI group, with a lower number of confabulations. Further analyses revealed CCR was largely responsible for this increase in correct recall. CCR is a very promising interview technique which allowed the interviewer to obtain more detailed information without additional questions and may have, in certain situations, several practical advantages over a questioning phase.

      Increasing recall is crucial for investigative interviews. The enhanced cognitive interview (ECI) has been widely used for this purpose and found to be generally effective. We focused on further increasing recall with a new interview strategy, category clustering recall (CCR). Participants watched a mock robbery video and were interviewed 48 hours later with either the (i) ECI; (ii) revised enhanced cognitive interview 1 (RECI1) — with CCR instead of the change order mnemonic during the second recall; or (iii) revised enhanced cognitive interview 2 (RECI2) — also with CCR but conjunctly used with ‘eye closure’ and additional open‐ended follow up questions. Participants interviewed with CCR (RECI1 and RECI2) produced more information without compromising accuracy; thus, CCR was effective. Eye closure and additional open‐ended follow up questions did not further influence recall when using CCR. Major implications for real‐life investigations are discussed.
