“…Participants who chose at least one opposite term developed more novel concepts. For one of the problems, the increase in novelty was statistically significant (Chiu & Shu, 2008). Since this most recent previous study was a penand-paper experiment where only final results were collected, the follow-up think-aloud experiment reported here will provide more insight into the use of dichotomous stimuli in concept generation.…”

“…The relatively small number of participants in think-aloud studies is generally accepted, provided other methods are used in conjunction (Visser, 2006), which we have and reported elsewhere (Chiu & Shu, 2007b;Chiu & Shu, 2008).…”

“…The challenge is to train the raters without biasing them. In experiments where a large number of concepts are collected, it is possible to have novelty defined based on the number of distinct concepts per concept category, as done in our recent work (Chiu and Shu, 2008). However, in think-aloud experiments where there is typically a smaller sample size, (time and resource limitations prevent the use of a large number of participants), novelty as perceived by independent raters may be the best approach.…”

The relationship between language and reasoning motivates us to study the use of language within engineering design. This paper describes our continued investigation of language as stimuli for concept generation. Specifically we investigate dichotomous lexical stimuli that are related to the problem in either a disagreeing, incongruent manner or in an agreeing, congruent manner. This is a follow-up investigation where we extend previous experiments to include both congruent and incongruent stimuli to enable comparison of differences between designer behavior and concepts. A between-subjects think-aloud experiment was performed where participants were presented with a problem and asked to generate concepts to address the problem. Half the participants were provided with incongruent stimuli and the remaining were provided with congruent stimuli. Participants provided with incongruent stimuli used the stimulus words as verbs more often than the participants provided with congruent stimuli. Verbs possess several properties desirable for use as design stimuli including the increased introduction of new lexicalized concepts to the concept generation process. When two independent raters scored the concepts, there was a positive correlation between the raters that concepts developed with incongruent stimuli were more novel. Understanding the effects of different lexical stimulus types on concept generation contributes to the development of design support tools that exploit the relationship between language and reasoning to increase design novelty.

“…The first experiment was a pen-and-paper experiment involving 42 fourth-year engineering students (Chiu and Shu, 2008a). Stimuli were verbs oppositely and similarly related to the functional keywords of each problem generated using various thesauri (e.g., Oxford, 2003), and to other words in the stimulus set.…”

We have been studying the effects of language stimuli on design concept creativity. We are motivated to study language and design because of the established relationship between language and cognitive processes central to design such as reasoning. As creativity is an important measure of design, many design methods use stimuli with the aim of increasing concept creativity. Language relationships such as the opposition relationship provide a systematic method of generating non-obvious stimuli that may increase concept creativity. In this paper, we summarize and discuss two experiments where participants used oppositely related and similarly related word stimuli in conceptual design. We found that designers using oppositely related word stimuli developed more novel concepts. We also observed that opposite stimuli elicited designer behaviours that may encourage creative concepts. These results suggest that opposite stimuli is a practical method for encouraging creative design.
