Dataset for: Influence of colour vision on attention to, and impression of, complex aesthetic images

Humans exhibit colour vision variations due to genetic polymorphisms, with trichromacy being the most common, while some people are classified as dichromats. Whether genetic differences in colour vision affect the way of viewing complex images remains unknown. Here, we investigated how people with different colour vision focused their gaze on aesthetic paintings by eye-tracking while freely viewing digital rendering of paintings and assessed individual impressions through a decomposition analysis of adjective ratings for the images. Gaze concentrated areas among trichromats were more highly correlated than those among dichromats. However, compared to the brief dichromatic experience with the simulated images, there was little effect of innate colour vision differences on impressions. These results indicate that chromatic information is instructive as a cue for guiding attention, whereas the impression of each person is generated according to their own sensory experience and normalised t..., Gaze data Gaze data were acquired using Tobii Pro X2-60 (Tobii Technology AB, Danderyd, Sweden) at a sampling rate of 60 Hz during a 30 s viewing of each painting. Impression data Impression data were obtained as ratings for 23 adjective pairs after viewing each painting. The presentation of the stimulus images, control of the gaze measurement device, and data acquisition were performed using a custom program in Psychtoolbox3, which was run in MATLAB (Mathworks, Natick, MA, USA)., Codes with extension \"m\" require the MATLAB environment. Codes with the extension \"R\" require the R statistical environment. Different versions of MATLAB and R may affect the codes. Octave can be used as an open-source alternative to MATLAB; however, its operation is not guaranteed.人类的色觉因遗传多态性存在个体差异，其中三色视觉（trichromacy）最为常见，部分个体被归类为二色视觉者（dichromats）。色觉的遗传差异是否会影响人们对复杂图像的视觉感知方式，目前尚不明确。本研究借助眼动追踪（eye-tracking）技术，探究了不同色觉人群在自由观赏数字渲染画作时的注视模式，并通过对图像形容词评分的分解分析，评估了个体的主观观感。三色视觉者的注视集中区域相关性高于二色视觉者。然而，相较于对模拟图像的短暂二色视觉体验，先天色觉差异对个体观感的影响微乎其微。本研究结果表明，色彩信息可作为引导注意力的有效线索，而个体观感则由自身的感官体验生成并经标准化处理…… 眼动数据（Gaze data） 眼动数据采用Tobii Pro X2-60眼动仪（Tobii Technology AB，丹德吕德，瑞典）采集，采样率为60 Hz，每名受试者观看每幅画作的时长为30秒。 印象数据（Impression data） 受试者在观赏每幅画作后，需对23组形容词对进行评分，以此获得印象数据。 刺激图像的呈现、眼动测量设备的控制及数据采集流程，均通过运行于MATLAB（MathWorks，内蒂克，马萨诸塞州，美国）环境下的Psychtoolbox3自定义程序完成。 扩展名为".m"的代码需依托MATLAB环境运行；扩展名为".R"的代码需依托R统计环境运行。不同版本的MATLAB与R可能会对代码运行产生影响。Octave可作为MATLAB的开源替代方案，但其运行效果无法得到保障。
