根据身体特异性假说，人类优先将积极的特征与他们更流畅地互动的优势侧联系起来，将消极的特征与他们更笨拙地行动的非优势侧联系起来。目前的研究调查了两个临床人群的内隐空间-效价映射，即单侧中风患者和肢体缺失患者。在这两项研究中，我们的发现为身体特异性假说提供了普遍支持，并提出了重要的警告。具体来说，身体特异性效应在两组右撇子左侧运动流畅性障碍的个体中比健康对照组更容易检测到。这可能是因为前者可以获得更流畅的经验，他们的优势手，因为他们专门使用完整的手自给自足，这可能会增加他们的偏见，以“正确的是好的”模式。综上所述，结果提供了一致的证据表明，动作流畅性的个体差异可能会缓和身体特异性效应。
According to the Body-Specificity Hypothesis, humans preferentially associate positive features with their dominant side with which they interact more fluently, and negatives features with their non-dominant side with which they act more clumsily. The current research investigated implicit space-valence mappings in two clinical populations, namely, patients with unilateral stroke and individuals who suffered the loss of a limb. Across the two studies, our findings offered general support for the Body-Specificity Hypothesis with important caveats. Specifically, the body-specificity effect was more detectable in the two groups of right-handed individuals with motor fluency impairment on their left side than healthy controls. This is possibly because the former can gain more fluent experience with their dominant hand since they exclusively use the intact hand for self-sufficiency, which may increase their bias toward “right-is-good” pattern. Taken together, the results provided converging evidence that individual differences in action fluency may moderate the body-specificity effect.
