最近，一些研究者已经开始将创意生成（IG），即有意产生新设计的过程，作为一种主要基于记忆的活动进行概念化。在本文中，我们考虑了心理的、基于记忆的IG模型如何帮助我们理解设计IG。我们介绍了一个这样的模型，并进行了修改，用于概念产品设计的实验。在这个模型中，IG过程分为两个阶段：记忆采样，然后是想法产生。我们利用这个模型来解释设计IG的刺激和固定效应。我们对该模型中与设计IG相关的两个预测进行了实证评估——情境线索对记忆抽样的影响，以及言语刺激对想法产生的影响。这些问题在一项涉及50名工程专业学生的实验中得到了调查。对产生的想法的分析表明，操作影响了想法，尤其是上下文线索，是设计任务的一个有影响力的部分。我们还表明，缺乏上下文信息可以激活上下文默认策略。我们在本文的结论中反思了这些发现对设计实践和教育的影响。
Recently, several investigators have begun to conceptualise idea generation (IG), the process by which new designs are deliberately produced, as a predominantly memory-based activity. In this paper, we consider how psychological, memory-based IG models can help us to understand design IG. We introduce one such model with modifications for experimentation in conceptual product design. In this model, the IG process is divided into two phases: memory sampling succeeded by idea production. We utilise this model to explicate stimulation and fixation effects in design IG. We evaluated empirically two predictions derived from the model that are relevant to design IG - the effect of contextual cueing on memory sampling, and the effect of verbal stimulation on idea production. These questions were investigated in an experiment involving 50 engineering students working individually. The analysis of generated ideas showed that the manipulations affected the ideas, and the contextual cues especially, were an influential part of the design assignments. We also showed that the absence of context information can activate a contextual defaulting strategy. We reflect on the implications of these findings for design practice and education in the conclusions of this paper.
