This study reports a synaesthete, GW, who experiences synaesthetic colours in response to a limited range of stimuli-namely those that have an emotional connotation. GW is significantly more consistent than a group of controls, and shows a Stroop-like congruency effect when the text colour differs from that reported for her synaesthetic photisms. The names of people who are known personally to GW are more likely to induce a synaesthetic colour than names referring to people with whom she is not personally acquainted and other categories of word (including colour names themselves). This feature resembles a number of reports in the historical literature on synaesthesia. This is explained by the fact that these stimuli are more likely to elicit an emotional response. In support of this, other words that have an emotional connotation (e.g., "love") have a tendency to elicit a synaesthetic response. The valence of the emotion (positive vs. negative) may have some role to play in determining the colour of the stimulus. It is concluded that emotion-colour synaesthesia is a genuine, if unusual, form of synaesthesia.
这项研究报告了一位联觉者 GW，他会对有限范围内的刺激产生联觉颜色，这些刺激通常具有情感内涵。GW 的一致性明显高于一组对照组，并且当文本颜色与她报告的联觉幻觉颜色不同时，会出现类似于斯特鲁普效应的一致性效应。GW 认识的人的名字比她不认识的人的名字和其他类别的词（包括颜色本身）更有可能引起联觉颜色。这一特征类似于历史文献中关于联觉的许多报告。这是因为这些刺激更有可能引起情感反应。支持这一观点的是，其他具有情感内涵的词（例如“爱”）往往会引起联觉反应。情绪的效价（积极与消极）可能在确定刺激的颜色方面起着一定的作用。因此可以得出结论，情感-颜色联觉是一种真实的、尽管不寻常的联觉形式。
