根據先前的物聯網介面評估計畫,研究團隊認為現行的使用者經驗研究實務場域尚缺乏一個更有效率的心智模型量測方法,而本研究認為概念圖是其中最適合的選擇。概念圖作為一種將個人認知架構以概念節點和其間關係作為表徵的圖形,同時符合計畫中的觀察結果和實際應用需求。
為了確認此量測方法和經由客觀計算產出之概念圖相似值指數可被應用於滿足實務需求,本研究先以另一經由主觀感知產生的相似度分數作為效標,並計算兩者之間的相關程度作為相似值指數的效標關聯效度,最終兩個變數之間呈現中等程度的相關 (r = 0.513, p < .01)。再者,將兩個變數分別作為應變數 (y),並協同可能影響概念圖相似度的預想影響因子集合產生兩個迴歸模型,用於檢視、比較兩種相似度的可能判斷來源組成。根據迴歸模型,主觀認知相似度主要反映較高層次的圖形特性與作答者背景知識,而相似值指數則涵蓋全部層次的圖形特徵以及作答者認知。
綜上所述,概念圖是一個囊括靈活性、適應性、經濟性、自動化可能和信效度的心智模型測量方法。若評分和執行方法設計得宜,此量測方法可被廣泛應用於各種目的的心智模型測量,亦可橫跨所有產品開發階段。
Based on previous IoT UI evaluation project, the need for a more efficient mental model measurement tool in UX research practices was identified, and concept mapping was considered the ideal candidate. Concept mapping is a kind of cognitive structure presentation that reflects the person’s mind by concept nodes and relationships between, which matches prior observations and meets practical needs.
To validate the method and corresponding objectively-calculated closeness index as the similarity parameter, the subject-perceived similarity was utilized to measure the criterion-related validity, indicating a moderate correlation between the two (r = 0.513, p < .01). Next, the two variables than served as the response (y) in fitted regression models, for further contributory factor inspection and comparison. As a result, subjective similarity reflects mainly the higher-level graphical features and subject’s background knowledge, while the other grasp all aspects and local graphical features.
In conclusion, concept mapping possesses many advantages for it being flexible, adaptable, economical, automatable, and reliable as a mental model measurement and assessment tool. If designed properly, the method is capable of being applied for various purposes as well as across design development stages.
