Influences of embodied interactions on the affective evaluation of digital pictures: Developing novel experimental multi-touch paradigms to examine the interplay of space-valence associations, action-contexts, and hand-proximity effects

当前的建议旨在推进我们对空间效价关联（上/右-积极；下/左-消极）、动作语境和手接近效应如何共同影响空间多点触摸互动背景下情感数字图片的情感评估的理论理解。然而，要做到这一点，这个建议建立在我们自己之前基于顺序“触摸和滑动”交互的研究中提出的几个悬而未决的问题之上，这些问题需要澄清。这些问题可以综合为三个主要的研究问题（RQ）：a)我们的研究结果表明，触摸交互比滑动交互更能影响价评价。然而，由于这两种相互作用都是按顺序进行的，因此尚不清楚将触摸与滑动分开是否会产生相似的结果，或者相反，触摸和滑动是否会对效价评估产生独立的因果影响（动作上下文的rq1）。因此，触摸和滑动将被独立调查。b)由于在我们之前的研究中，所有图片都显示在触摸屏显示器的垂直或侧向边缘，因此很难确定对效价评估的影响是否取决于(1)方向运动或(2)刺激位置。这是一个需要澄清的问题（RQ 2 on action context）。c)最后，我们的研究没有调查在没有先前的手动交互时，滑动和触摸交互后的效价评估是否以及如何与以空间位置或方向运动为特征的相同刺激的评估有本质差异。因此，本提案旨在澄清这一问题（手邻近效应的RQ）。基于这些考虑，总共需要6项研究（S1-S6）来系统地检查空间价关联、相互作用背景和手接近效应之间的相互作用。为了满足(1)在(2)垂直或横向空间维度上的触摸或滑动交互(3)主要的右手或非主要的左手（横向交互）的需求，需要进行的研究数量。

The current proposal aims at advancing our theoretical understanding of how space-valence associations (up/right - positive; down/left - negative), action contexts, and hand-proximity effects together shape affective evaluations of affective digital pictures in the context of spatial multi-touch interactions. To do so, however, this proposal builds upon several open issues that were raised by our own prior studies based on sequential "touch-and-swipe" interactions and that need to be clarify. These issures can be synthesized in three main research questions (RQ):a) Our findings suggested that touch interactions influenced valence evaluations more than swipe interactions. However, since both interactions were performed in a sequence, it remains unclear whether disentangling touches from swipes will result in similar results, or whether on the contrary both, touches and swipes, will yield independent causal effects on valence evaluations (RQ 1 on action contexts). Accordingly, touches and swipes will be investigated independently.b) Since in our prior studies, all pictures were displayed at vertical or lateral margins of the touchscreen monitor, it was very difficult to determine whether effects on valence evaluations depended on (1) directional movements or (2) stimulus locations. This is a question that needs to be clarified (RQ 2 on action context).c) Finally, our studies did not investigate whether and how valence evaluations after swipe and touch interactions would substantially differ from evaluations of the same stimuli characterized by spatial locations or directional motion when no prior manual interaction is involved. Therefore, the current proposal aims at clarifying this question (RQ on hand-proximity effects).Based on these considerations, a total of 6 studies (S1-S6) will be necessary to systematically examine the interplay between space-valence associations, interaction-contexts, and hand-proximity effects. The number of studies required to respond to the need of addressing (1) touch or swipe interactions across the (2) vertical or lateral spatial dimensions with the (3) dominant right or non-dominant left hand (for lateral interactions).
