Multi-attribute decisions have mainly been studied with a paradigm in which researchers provide participants with all necessary information. However, many decisions require retrieval of relevant cue information from long term memory. Only a handful of studies examined these memory-based decisions and the information integration strategies used. The results have been mixed: Whereas some found a preponderance of simple lexicographic heuristics that ignore certain information, others found mainly compensatory strategies which take all weighted cue information into account. Within studies, this can be manipulated by varying the representation format of information, but between studies, the reasons for this discrepancy remain elusive. Furthermore, exemplar-based reasoning has been found in a recent replication of a study that did not find exemplar-effects originally. However, all studies used different materials, paradigms, cue formats etc. The project aims to illuminate the role of several cognitive factors that may influence strategy selection. A preliminary framework was extracted from the results in the literature yielding testable hypotheses about potentially important variables that are subjected to ceteris paribus tests in 6 experiments.

多属性决策主要是研究人员提供参与者所有必要的信息的范式。然而，许多决策需要从长期记忆中检索相关线索信息。只有少数研究检查了这些基于记忆的决策和所使用的信息整合策略。结果好坏参半：虽然有些人发现了一个简单的词典编纂的优势，忽略某些信息，其他人发现主要是补偿策略，考虑到所有加权线索信息。在研究中，这可以通过改变信息的表示格式来操纵，但在研究之间，这种差异的原因仍然难以捉摸。此外，基于范例的推理已被发现在最近的一项研究，最初没有发现范例效果复制。然而，所有的研究都使用了不同的材料，范式，提示格式等项目的目的是阐明几个认知因素，可能会影响策略选择的作用。一个初步的框架提取的结果，在文献中产生可检验的假设，潜在的重要变量，在6个实验中进行其他条件相同的测试。
