Exploring modality-specificity and conceptual generalization of response-effect anticipation

在认知心理学中，“意念运动”方法认为，反应是由对预期感觉结果(“反应效应”)的预期控制的。然而，反应和预期效果之间关系的具体性质仍然很不清楚。本项目旨在探讨两个相互关联的问题。首先，我们考察了反应通道(例如，手动与声音)和效果通道(例如，视觉与听觉)的映射是否影响了效果预期的影响。其次，我们探讨了效应预期在反应控制中的作用是否可以从反应和效应之间的知觉相似关系概括为概念关系。我们使用反应-效应(R-E)兼容范式和可预测的效应刺激来研究这些问题。以前的工作表明，相对于R-E不相容的条件，R-E相容(关于“维度重叠”)有助于促进表现，这表明预期效应的表征先于反应。利用这一范式的变化，我们系统地操纵反应和效果的通道，以检验通道映射在效果预期中的作用。此外，我们通过操纵预期效果的知觉表面特征来检验反应和效果的概念重叠，从而使知觉上的非匹配效应能够保持与反应的概念关系，例如在双语迁移中(即言语反应的语言和听觉反应效果的语言)。综上所述，该项目将完善关于模式特殊性和概念R-E重叠这两个互补问题的理念运动框架，从而有助于更好地理解反应控制机制。

In cognitive psychology, the "ideomotor" approach proposes that responses are controlled by anticipations of intended sensory consequences ("response effects"). However, the specific nature of the relation between response and anticipated effect is still largely unclear. The present project aims to explore two interrelated issues. First, we examine whether the mapping of response modality (e.g. manual vs. vocal) and effect modality (e.g., visual vs. auditory) influences the impact of effect anticipation. Second, we explore whether the role of effect anticipation in response control can be generalised from perceptual similarity relations between responses and effects to conceptual relations. We investigate these issues using a response-effect (R-E) compatibility paradigm with predictable effect stimuli. Previous work showed that R-E compatibility (with respect to "dimensional overlap") facilitates performance relative to R-E incompatible conditions, suggesting that representations of anticipated effects precede the response. Using variations of this paradigm, we systematically manipulate the modality of responses and effects to examine the role of modality mapping in effect anticipation. Moreover, we examine conceptual overlap of response and effect by manipulating perceptual surface characteristics of the anticipated effects, so that perceptually non-matching effects can maintain the conceptual relation to the response, such as in bilingual transfer (i.e., language of verbal responses and of auditory response effects). Taken together, this project will refine the ideomotor framework with respect to the complementary issues of modality-specificity and conceptual R-E overlap and will thus contribute to a better understanding of the mechanisms of response control.
