The lateralisation of colour processing is not well understood, although there is a reasonable amount of evidence indicating a right hemisphere bias for colour processing. Tasks that require colour naming are associated with a left hemisphere bias and it is likely that asymmetry of colour processing is influenced by task demands. It is not known whether object colour knowledge is lateralised. In the current study colour and achromatic Mondrian-like objects were presented to either the left or right hemisphere to assess the lateralisation of colour processing. Participants were required to judge whether the objects were colour or achromatic. To assess colour knowledge, congruently and incongruently coloured familiar objects were presented to either the left or right hemisphere and participants were required to judge whether the objects were correctly or incorrectly coloured. The data show that both colour processing and colour knowledge are associated with a right hemisphere bias.

颜色知识：右半球在颜色处理和对象颜色知识中的作用。

尽管有合理数量的证据表明颜色处理的右半球偏斜，但对颜色处理的偏侧化还没有很好的理解。要求颜色命名的任务与左半球偏斜相关，并且颜色处理的不对称性很可能受任务要求的影响。尚不清楚对象颜色知识是否被横向化。在当前的研究中，将彩色和无彩色蒙德里安样物体呈现给左半球或右半球，以评估色彩处理的横向化。要求参与者判断物体是彩色的还是消色差的。为了评估色彩知识，分别向左半球或右半球呈现颜色一致且不一致的熟悉对象，并且要求参与者判断这些对象是正确着色还是错误着色。数据表明，色彩处理和色彩知识均与右半球偏斜相关。
