1 Use of a Hybrid Interview Method to Retrieve Memories Created During Decision Making Dana e. hirn, ronald p. fisher, & rolando n. carolFlorida international university
2 Goals of the Current Research Create a novel interview method to elicit the maximum amount of information for memories of decisionsExamine the effectiveness of this interview method in a variety of ways in a controlled setting
3 Critical Decision Method Gather information from decision makers about their cognitive processes when they assess situations, decide on a course of action, and follow through on their decisions (Crandall, Klein, & Hoffman, 2006).
4 Cognitive InterviewAn interviewing technique that uses concepts of social dynamics, memory, cognition, and communication to assist interviewers in eliciting the maximum amount of accurate, detailed information from witnesses of an event (Fisher & Geiselman, 1992).

13 Study 1 Method Phase I: Ethical scenario Phase II: Decision Phase III: Immediate interview (CDM-CI Hybrid or Free Narrative)
14 Study 1 ResultsAnalyses indicate significantly more information elicited from the hybrid (M=8.88, SD=1.93) compared to the free narrative (M=3.00, SD=1.51),t(30)=-9.61, p<.001.Information Elicited
15 Study 2 Method Phase I: Ethical scenario Phase II: Decision Phase III: Delayed interview – two days (CDM-CI Hybrid or Free Narrative)
16 Study 2 Method Phase I: Ethical scenario Phase II: Decision Phase III: Delayed interview – two days (CDM-CI Hybrid or Free Narrative)
17 Study 2 ResultsAnalyses indicate significantly more information elicited from the hybrid (M=8.81, SD=1.91) compared to the free narrative (M=2.44, SD=1.15),t(30)=-9.84, p<.001.Information Elicited
18 LimitationsDifficult to verify information for memories of decisions elicited in interviews80% of information about decisions provided by participants across studies and conditions was matched with verbal information in the discussionNot yet directly compared with the CDM or CIComparison of CDM-CI Hybid to the CDM and CIAre participants simply recalling their conversations rather than their memories of decisions?Single-participant, silent decision making activities
