面部表情识别的个体差异评估通常需要解决两个主要问题：(1)高一致性水平（天花板效应）和(2)不同情绪的不同难度水平。我们提出了一种新的评估方法，旨在量化识别六种基本情绪的个体差异，即对面部基本情绪的敏感性。“我们试图通过使用变形技术和项目反应理论（IRT）来解决两个主要的评估问题。我们使用变形来创造具有不同识别难度的中级混合面部表情刺激。IRT的应用使我们能够估计个体潜在的特质水平（敏感性分数），而不受构成困难的刺激属性的影响。在一系列的两个实验中，我们证明了敏感性评分成功地解决了两个主要的评估问题及其伴随的个体差异。有趣的是，对不同情绪的敏感性得分的相关分析显示，快乐和不快乐情绪识别之间存在正交性。据我们所知，这是第一份关于快乐认知独立性的报告，不受刺激难度的影响。
The assessment of individual differences in facial expression recognition is normally required to address two major issues: (1) high agreement level (ceiling effect) and (2) differential difficulty levels across emotions. We propose a new assessment method designed to quantify individual differences in the recognition of the six basic emotions, ‘sensitivities to basic emotions in faces.’ We attempted to address the two major assessment issues by using morphing techniques and item response theory (IRT). We used morphing to create intermediate, mixed facial expression stimuli with various levels of recognition difficulty. Applying IRT enabled us to estimate the individual latent trait levels underlying the recognition of respective emotions (sensitivity scores), unbiased by stimulus properties that constitute difficulty. In a series of two experiments we demonstrated that the sensitivity scores successfully addressed the two major assessment issues and their concomitant individual variability. Intriguingly, correlational analyses of the sensitivity scores to different emotions produced orthogonality between happy and non-happy emotion recognition. To our knowledge, this is the first report of the independence of happiness recognition, unaffected by stimulus difficulty.
