This work aimed to assess the role of manual laterality in action coding strategies and, subsequently, in environmental features relevant for each hand's action. Relying on Eder and Hommel's (2013) proposal, we distinguished stimulus-related and end state-related consequences in a Simon paradigm where right-handed participants were divided into two groups, one responding with gloves and one without. Two objects were presented pictorially: one for which sensory consequences of grasping were negatively valenced (a chestnut burr), and one for which they were positively valenced (an apricot). By these means, stimulus and end-state effects could be assessed separately, along with the relevance of each feature of the experimental settings. Results showed that the use of one's dominant or non dominant hand gives rise to different repercussions of stimulus-related and end state-related effects on response: Responses made with the right (dominant) hand were based on an elaborated coding (representing features of stimulus-related and end state-related consequences of action). In contrast, responses made with the left (non dominant) hand seemed to be based on a less elaborated coding (not taking into account end-state consequences of an action).

抓栗子毛刺。

这项工作旨在评估手动横向性在动作编码策略中的作用，以及随后在与每只手的动作相关的环境特征中的作用。根据Eder和Hommel（2013）的建议，我们在西蒙范式中区分了与刺激相关和最终状态相关的后果，在该范例中，惯用右手的参与者分为两组，一组戴着手套，而另一组没有手套。以图形方式展示了两个对象：一个对抓握的感官后果呈负价（栗子毛刺），另一个对正抓握的感官后果（一个杏子）。通过这些方法，可以分别评估刺激和最终状态的影响，以及实验设置中每个功能的相关性。结果表明，使用一个' 显性或非显性手对响应产生不同的影响，即与最终状态相关的响应：用右手（显性）做出的响应基于精心设计的编码（代表与刺激相关和最终状态的特征行动的相关后果）。相反，左手（非优势手）做出的响应似乎是基于不太复杂的编码（不考虑动作的最终状态后果）。
