摘要

嗅觉偏侧化的证据是混合的,尽管左脑对气味识别的好处似乎是可能的。功能偏侧化是否受到性别和利手性等变量的调节,此前已经进行了探讨。然而,目前还没有关于精神病和共情人格特征本身是否会影响嗅觉偏侧化和是否会影响嗅觉功能的测试。80名男性和女性参与了气味阈值、识别和辨别能力的单鼻测试,并完成了精神病和同理心的标准化测试。虽然左脑对气味识别和辨别有明显的好处,但我们发现没有证据表明精神病或同理心会减缓这些影响。将目前的研究数据与以往的研究数据相结合,我们发现精神病与较差的气味辨别和识别相关,而同理心与增强的气味辨别和识别相关,这表明嗅觉、精神病和同理心之间存在共性。

Investigating Left- and Right-Nostril Olfactory Abilities with Respect to Psychopathy

Investigating Left- and Right-Nostril Olfactory Abilities with Respect to Psychopathy

Evidence for olfactory lateralization is mixed, although a left-sided benefit for odor identification seems likely. Whether lateralization of function is moderated by variables such as gender and handedness has been previously explored. However, there has been no test of whether psychopathy and empathy—personality characteristics which may themselves affect lateralization and which can affect olfactory function—moderate olfactory lateralization.

Eighty men and women engaged in mono-rhinal testing for odor threshold, identification, and discrimination ability, as well as completing standardized measures of psychopathy and empathy.

While there was a clear left-sided benefit for odor identification and discrimination, we found no evidence that psychopathy or empathy moderated these effects. When the current data were combined with that from previous studies, we found that psychopathy was correlated with poorer odor discrimination and identification, whereas empathy was correlated with enhanced discrimination and identification, pointing to processing commonalities between olfaction, psychopathy, and empathy.
