The Process of Replication Target Selection in Psychology: What to Consider?

Increased execution of replication studies contributes to the effort to restore credibility of empirical research. However, a second generation of problems arises: the number of potential replication targets is at a serious mismatch with available resources. Given limited resources, replication target selection should be well justified, systematic, and transparently communicated. At present the discussion on what to consider when selecting a replication target is limited to theoretical discussion, self-reported justifications, and a few formalized suggestions. In this Registered Report, we proposed a study involving the scientific community to create a list of considerations for consultation when selecting a replication target in psychology. We employed a modified Delphi approach. First, we constructed a preliminary list of considerations. Second, we surveyed psychologists who previously selected a replication target with regards to their considerations. Third, we incorporated the results into the preliminary list of considerations and sent the updated list to a group of individuals knowledgeable about concerns regarding replication target selection. Over the course of several rounds, we established consensus regarding what to consider when selecting a replication target

Exploring the decision dynamics of risky intertemporal choice

Previous research on the effects of probability and delay ondecision-making has focused on examining each dimensionseparately, and hence little is known about when these dimen-sions are combined into a single choice option. Importantly,we know little about the psychological processes underlyingchoice behavior with rewards that are both delayed and proba-bilistic. Using a process-tracing experimental design, we mon-itored information acquisition patterns and processing strate-gies. We found that probability and delay are processed se-quentially and evaluations of risky delayed prospects are de-pendent on the sequence of information acquisition. Amongchoice strategies, directly comparing the values of each dimen-sion (i.e., dimension-wise processing) appears to be most fa-vored by participants. Our results provide insights into the psy-chological plausibility of existing computational models andmake suggestions for the development of a process model forrisky intertemporal choice
