Abstract

The role of search processes and the knowledge used in the activity of designing has been receiving increasing attention in the areas of artificial intelligence, the study of design, and cognitive psychology. More recently, with the development of expert systems, considerable attention has been focused on the representation and retrieval of expert knowledge. What has not been addressed, however, is whether or not an expert represents, accesses and utilizes all knowledge equivalently. The design-fixation effect, where pictures of design instances presented as part of a design problem result in the reproduction, by student and practising designers, of aspects of the presented instance, indicates that certain types of knowledge are more privileged in the design process than others. The results of a preliminary experiment, which examined the role of pictures of different types of instances, verbal descriptions of those instances, and variations in the familiarity of instances in the fixation effect, are reported. Pictorial information was shown to have no effect if the instance was unfamiliar, and equally familiar pictures were found to produce both design fixation and increased variety in design. Verbal descriptions of two of the pictured designs also produced effects, although these were much reduced in comparison with those of the pictorial material that produced fixation effects. While preliminary, these results indicate a particularly important direction for research, the results of which could be important for artificial intelligence, the study of design, and the psychology of design processes.

Considering cognitive biases in design: an integrated approach
2024, Procedia Computer Science
Design is a dynamic, decision-driven process, often guided by intuition and experience. It can be susceptible to cognitive biases, systematic deviations in information processing and decision making, which have been recognized as influential factors affecting expert judgment in multiple domains. Although some studies in the design field have investigated and proposed methods to address specific biases, such as the confirmation bias, there is currently no comprehensive approach in the literature to make designers aware of the various biases that may manifest during the design process. The main contribution of this article is to provide designers with a broad overview of the biases that may be involved within the three principal areas of design cognition: problem formulation, concept generation and concept evaluation. It also proposes a novel and workable methodology to facilitate designers' recognition and mitigation of biases through metacognition, while favoring the implementation of more specific correction strategies.
Factors influencing bid-winning performance in mixed crowdsourcing: The persuasive effect of credible information sources
2021, Technology in Society
Citation Excerpt :
Among the four types of credibility, surface credibility describes the extent of belief the perceiver has in someone or something based on a simple inspection [59]. Excessive display of previous cases may make the contractee too familiar with the contractor's style, which will reduce the perceived novelty of solutions [60,61] and negatively influence the bid-winning performance. Wadhwa and Kotha [62] investigate the conditions under which corporate venture capital (CVC) investments affect knowledge creation for corporate investors.
Mixed crowdsourcing is increasingly becoming the main organizational model of domestic crowdsourcing platforms. However, research on the interpretation of winning performance fails to focus on the persuasive effect of the credibility of the contractor's information source on the contractee's decision making. Based on source credibility theory (SCT), this study constructs a model of the factors influencing the contractor's bid-winning performance based on three aspects—credibility, professionalism, and attractiveness—and examines the moderating effect of positive contractor evaluations from previous tasks on the bid decision. The results reveal that integrity guarantee and contact authentication (which belong to the credibility dimension), as well as ability level and professional identity (professionalism dimension) positively affect the contractor's bid-winning performance, and that an inverted-U-shaped relationship exists between the number of services displayed by the contractors (attractiveness dimension) and bid-winning performance.
The effects of representation on idea generation and design fixation: A study comparing sketches and function trees
2016, Design Studies
Citation Excerpt :
This is the exact definition of fixation and an undesirable engineering design behavior. Most previous research studies on design fixation use examples represented in only one form, predominantly sketches (Fu et al., 2010; Jansson & Smith, 1991; Purcell & Gero, 1992). Only a few studies specifically explored the influence of different representations on design fixation.
Representations in engineering design can be hand sketches, photographs, CAD, functional models, physical models, or text. Using representations allows engineers to gain a clearer picture of how a design works. We present an experiment that compares the influence of representations on fixation and creativity. This experiment presents designers with an example solution represented as a function tree and a sketch, we compare how these different external representations influence design fixation as they complete a design task. Results show that function trees do not cause fixation to ideas compared to a control group, and that function trees reduce fixation when compared to sketches. Results from this experiment show that function tree representations offer advantages for reducing fixation during idea generation.
