【正文】 alysis. The inspection of Fig. 4b showed that, for the Website designers, the results are relatively similar to those in the previous analysis, despite the different cluster boundaries. The main clusters contain the greens (80– 160176。 and 260176。 z = .054). Orange appeared to be an intermediate colour, as it was appreciated more than green (z .05) but did not differ significantly from magenta. Lastly, green was not significantly preferred to magenta. 9 The analysis of Website designer data also revealed a main effect of colour, Friedman chi2(4) = , p .001. Grey, blue and orange were preferred to green and magenta (all p .001). The differences between grey, blue and orange, and between green and magenta were not significant. In short, the homepages that obtained the highest scores (or the least low scores), whatever the participants? status, were the ones presented in blue and in orange. Contrary to users, professional designers also gave similar scores to homepages presented in grey. 5 Discussion First, the professional designers appeared to be more critical of the Webpages than the users. However, blue and orange were regarded as the most appealing colours by all participants, whatever their status. Website designers also liked (or at least did not dislike) grey, unlike the users. The choice of these three colours can partly be explained by the reported associations between these colours and emotions[43,47,41,18]. The result for blue, in particular, was in accordance with previous research, insofar as blue is frequently regarded as users? favourite colour, whatever their age and cultural context ., [63– 66]. Findings for orange contrasted with previous results suggesting that cooler colours are viewed more favourably than hotter ones. However, the warm effect conveyed by the orange homepage may have explained its high score. Finally, although grey is a neutral colour, it may also be regarded, to some extent, as an innovative feature by Web designers, allowing such Websites to be perceived as trendy. This relatively discreet colour may also have enhanced the way in which the information was set out on the homepage, thereby generating a semantic effect (accessibility of information structure) rather than an aesthetic one. To take our research one step further, a second, plementary experiment was conducted in order to determine the impact of these three colours (blue, orange and grey) on users? behaviours and cognitive processes. 6 Study 2: impact of colours on users’ behaviours and cognitive processes Hypotheses Our general hypothesis was that Website users would react differently according to the colour of the site they were exploring. For this experiment, three versions of the same site, corresponding to the different colours for which participants in the previous study had expressed a preference, were shown to new participants. In line with results of the first study, we expected that the three selected colours (blue, orange and grey) would have an impact on the users? judgements. Moreover, we hypothesized that these Website colours would also exert an influence on users? 10 behaviours and cognitive processes. More precisely, we expected that these colours would have an impact on both the users? searches for information and the way they memorized it. Therefore, the main originality of this experiment lays in the fact that the impact of the colours was analyzed with regard to both objective and subjective measurements. Three types of data were analyzed: (1) data relating t。 between each colour. In addition,we added a value corresponding to the grey. As the group supplying user data was larger than the group supplying designer data, the precise values of the colours were based on the users? data, as follows: orange (20176。) and oranges (20176。) and the greys (3176。 – analyzing the impact of three separate Website colours (selected on the basis of the findings of the first study) on users? behaviour, judgments and subsequent performance. 3 Study 1: colour appeal for Website users and designers Objectives and hypotheses We first conducted an exploratory study in the context of Websites in order to determine whether the users and designers of Websites judge the same colours to be appealing or unappealing. Colour appeal is defined as the degree to which colours used in Websites are perceived as pleasing, appealing and appropriate [50]. In our study, participants were provided with the homepage of an informational Website. Instead of forming precise hypotheses about the appeal of specific colours, we chose to develop numerous versions of the same homepage in order to expose participants to 23 different colours 6 across a broad spectrum (see 167。 本科生畢業(yè)論文外文翻譯 （ 2020 屆） 課題名稱： 基于行業(yè)區(qū)分的企業(yè)網(wǎng)站色彩設計的研究 學生姓名： 學 號： 202008301105 專業(yè)班級： 電子商務 081 班 指導教師： 姓名 學科 電子商務 職稱 講師 年 月 日 0 The impact of colour on Website appeal and users?cognitive processes Nathalie Bonnardel, Annie PiolatLudovic, Le Bigot Abstract:One of the challenges today in human–puter interaction is to design systems that are not only usable but also appealing to users. In order to contribute to meet this challenge, our general objective in the present study was to enhance current understanding of the perceptual features that favour users? interactions with Websites. This is a particularly important issue, as users? first impressions when they land on a site determine whether or not they stay on it. We conducted two experimental studies, focusing on one specific perceptual feature: Website colour. The first study in
