Using deception ethically: Practical research guidelines for researchers and reviewers.

This article reviews highlights in the literature on existing recommendations for ethical use of deception in psychological research. We conclude that ethical guidelines and aspirational statements set out by research policies and advisory panels on ethics must eventually be operationalized into concrete terms when introducing deception into a research design. Specific directives for using deception are especially important for new researchers developing projects and also for university/departmental reviewers who are being asked to evaluate the ethical standing of proposed research. We offer a checklist designed to cultivate the understanding of junior researchers and to facilitate the review process by instantiating the relevant general guidelines into a set of Y/N questions about intended research. Finally, the article presents empirical data from researchers and ethics reviewers who provided end-user evaluations of the tool. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

"Don't know" responding to answerable and unanswerable questions during misleading and hypnotic interviews.

"Don't know" (DK) responses to interview questions are conceptually heterogeneous, and may represent uncertainty or clear statements about the contents of memory. A study examined the subjective intent of DK responses in relation to the objective status of information queried, in the context of memory distorting procedures. Participants viewed a video and responded to answerable and unanswerable questions phrased in misleading or nonmisleading formats, while hypnotized or not hypnotized. Subjective meanings of DK responses were queried, and a recognition measure assessed the contents of memory. Lower DK and accuracy rates were consistently associated with unanswerable and misleading questions. One-third of DK responses were statements that the information had no not presented. When these were recoded, accuracy estimates for answerable questions decreased and more so for hypnotized participants. These results demonstrate that DK responses convey different types of information, thus accuracy estimates in studies that permit DK responses may be misestimated. Robust risks associated with asking unanswerable questions and asking questions at all were observed. Implications for working with DK responses during interviews are discussed.

Memory for future gambling wins.

Analogous to false memories for the past, gambling behavior may be influenced by the development of vivid, believed false “memories” for future gambling outcomes. We examined the degree to which believed memory-like representations for future gambling wins and losses were associated with prior substantial win experiences, frequency of gambling, risk for problem gambling, and other types of gambling expectancies. Regular gamblers with and without prior substantial wins rated the strength of a specific outcome expectancy, their belief that substantial gambling wins and losses would occur in the future, and rated the strength of “memory” for future gambling wins and losses. They then described a future win and a future loss and rated memory-like phenomenal characteristics for these events. Prior winners rated future wins as more believable relative to future losses, and rated future gambling outcomes as more memory-like than did gamblers without prior win experiences. Belief and memory for future wins correlated positively with frequency of gambling and positive response expectancies (e.g. relaxation when gambling). Belief and memory for future losses correlated with negative outcome expectancies and endorsement of problem gambling risk. Expecations about future wins and losses are likely influenced by believed memory-like representations for future wins and losses. (PsycINFO Database Record (c) 2011 APA, all rights reserved)
