The Implicit Relational Assessment Procedure (IRAP) has been successfully used to analyze the strength of symbolic relations. Taking advantage of this, Bortoloti, de Almeida, de Almeida, and de Rose (Frontiers in Psychology, 10(954), 2019) reported a higher relational strength in equivalence classes containing happy faces than in those containing negative faces. This so-called happiness superiority effect (HSE) was inferred from an IRAP that included stimuli presented during the equivalence training. Such HSE apparently had a stronger influence on IRAP performance than the equivalence training itself. In this article, we comment on these data and present a new analysis that supports a hypothesis raised by Bortoloti et al. (Frontiers in Psychology, 10(954), 2019) to account for a surprising IRAP performance in their experiment. Based on this, we discuss new avenues for the investigation of properties of relational responding using the IRAP.

隐式关系评估程序（IRAP）已成功用于分析符号关系的强度。利用这一点，Bortoloti，de Almeida，de Almeida和de Rose（Frontiers in Psychology，10（954），2019）报告称，在包含幸福面孔的对等类别中，与那些包含负面面孔的对等类别中的关系强度更高。这种所谓的幸福优势效应（HSE）是从IRAP推断出来的，其中包括在等效训练中出现的刺激。这样的HSE显然比同等训练本身对IRAP表现的影响更大。在本文中，我们对这些数据进行评论，并提出了支持Bortoloti等人提出的假设的新分析。（心理学前沿，第10期（954），2019）解释了他们实验中IRAP的惊人表现。基于此，我们讨论了使用IRAP研究关系响应属性的新途径。
