【摘要】：视觉搜索包括点搜索和路径搜索。为了探究颜色对路径搜索的影响,以及这种影响是否会受到主体认知方式的制约,从南京市某高校抽取了 83名大学生参加实验研究,除完成设定的路径搜索任务外,均完成《镶嵌图形测验》。研究中还考察了刺激图形的复杂度和被试性别的影响。实验采用5 (背景色:红、黄、蓝、绿、白)×2 (图形复杂度:简单、复杂)×3 (认知方式:偏场独立型者、中间型者、偏场依存型者)×2 (性别:男、女)的混合设计,其中背景色和图形复杂度为组内设计,认知方式和性别为组间设计,因变量为路径搜索任务的正确率和反应时。结果显示:(1)背景颜色在路径搜索过程中与性别产生交互作用,男生在蓝色和白色背景下的搜索速度显著快于女生;(2)背景颜色在路径搜索任务中与图形复杂度产生交互作用,并且存在显著的性别差异,即简单任务中,男女生在蓝色背景下差异大;复杂任务中,男女生在白色背景下差异大;(3)认知方式在路径搜索任务上的主效应显著,偏场独立型被试的搜索绩效显著快于中间型和偏场依存型;在复杂刺激材料下场独立型被试的反应时间明显少于其他两组被试,差异显著。研究结论:(1)不同背景色下,男女生的搜索速度存在差异,并且在蓝色背景下差异显著;(2)偏场独立型被试在路径搜索任务中的优势显著。(3)在路径搜索中,刺激的颜色特征,复杂程度以及主体性因素相互作用,构成较为复杂的感知-运动信息加工过程。
[Abstract]:Visual search includes point search and path search. In order to explore the influence of color on path search, and whether the influence is restricted by the cognitive mode of the subject, 83 college students were selected from a university in Nanjing to participate in the experimental study, in addition to completing the set path search task. The inlay figure test was completed. The effects of the complexity of the stimulus patterns and the sex of the subjects were also investigated. The experiment used a mixed design of 5 (background: red, yellow, blue, green, white) 脳 2 (graphic complexity: simple, complex) 脳 3 (cognitive style: biased field independent, intermediate, biased field dependent) 脳 2 (sex: male, female). The complexity of background color and graph is intra-group design, cognitive style and gender are inter-group design, and dependent variables are correct rate and response time of path search task. The results showed that: 1) the background color interacted with gender in the path search process, and the search speed of boys in blue and white background was significantly faster than that of female students.) background color interacted with the graph complexity in the path search task. And there are significant gender differences, that is, in simple tasks, male and female students differ greatly in blue background, and in complex tasks, male and female students differ greatly in white background.) the main effect of cognitive style on path search task is significant. The search performance of bias independent subjects was significantly faster than that of intermediate type and bias field dependent type, and the reaction time of the next independent subjects in complex stimulus materials was significantly lower than that of the other two groups, and the difference was significant. The results showed that under different background colors, the search speed of male and female students was different, and the difference was significant under blue background. 2) the advantage of skew field independent subjects in path search task was significant. 3) in path search, the color characteristics of stimulus were significant. The interaction of complexity and subjective factors constitutes a complex process of perceptual and motion information processing.
