ABSTRACT

We explored colour connotations in blind and sighted observers using the semantic differential technique. Participants rated colour terms on 17 semantic scales. At the group level, blind participants were similar to sighted on some scales, but had weaker colour associations on others, with significant individual differences. Two, in particular, produced ratings that were very similar to the sighted sample. We quantified individual differences amongst the blind participants by computing the difference between their ratings and the mean of the sighted participants for each colour on each scale. This “semantic similarity index” indicates how similar each blind participant was to sighted observers. The participants also rated dissimilarities between pairs of colour terms, which we subjected to multidimensional scaling. This also revealed large variability amongst the blind participants, with some producing colour spaces resembling those of the sighted. The semantic similarity index computed from the blind participants’ semantic differential data correlated strongly with the circularity of personal colour spaces derived from multidimensional scaling: observers who resembled the sighted on one measure tended to do so on the other. These observations provide strong, albeit indirect, support for the notion that semantics provide sufficient information for blind people to develop rich understandings of colour.

通过语言看颜色:盲人和盲人的颜色知识

摘要

我们使用语义差分技术探索了盲人和视力不佳的观察者的色彩内涵。参与者以17个语义量表对颜色术语进行了评分。在小组水平上,盲人参与者在某些程度上类似于看见的人,但在其他人身上颜色关联较弱,个体差异显着。特别是有两个样本产生的评级与目测样本非常相似。我们通过计算每种等级上每种颜色的盲人参与者的等级与有眼参与者的平均值之间的差异来量化盲人参与者之间的个体差异。该“语义相似性指数”表明每个盲人​​参与者与有眼力的观察者有多相似。参与者还对颜色项对之间的差异进行了评分,我们对其进行了多维缩放。这也揭示了盲人参与者之间的巨大差异,其中一些产生的色彩空间类似于视力的色彩空间。从盲人参与者的语义差异数据计算出的语义相似性指数与从多维缩放获得的个人色彩空间的圆度高度相关:在一种方法上类似于视力的观察者倾向于在另一种方法上这样做。这些观察结果为语义为盲人提供了足够的信息以发展对色彩的丰富理解的观点提供了强有力的支持,尽管是间接的。从盲人参与者的语义差异数据计算出的语义相似性指数与从多维缩放获得的个人色彩空间的圆度高度相关:在一种方法上类似于视力的观察者倾向于在另一种方法上这样做。这些观察结果为语义为盲人提供了足够的信息以发展对色彩的丰富理解的观点提供了强有力的支持,尽管是间接的。从盲人参与者的语义差异数据计算出的语义相似性指数与从多维缩放获得的个人色彩空间的圆度高度相关:在一种方法上类似于视力的观察者倾向于在另一种方法上这样做。这些观察结果为语义为盲人提供了足够的信息以发展对色彩的丰富理解的观点提供了强有力的支持,尽管是间接的。
