Is active perception better than passive perception? Examining the role of action in perception through a systematic literature review and comprehensive behavioral experiments

在过去的一年里，对主动和被动感知的研究沿着几个方向进行。首先，我们继续开发项目所涉及的研究设备。我们的第一个行为实验(如下所述)突出了实施中可能阻碍进一步进展的差距。因此，我们测量并最小化了实验系统组件之间所有可能的延迟，以便可以从运动、触觉输出和生理连续获取数据，并通过事件触发进行同步。第二，我们完成了一项行为研究。参与者使用我们的实验设备探索二维物体，并报告了他们对物体大小的估计。我们操纵了1)他们对探索性运动的控制，要么是主动的(有控制)，要么是被动的(没有控制)，以及2)他们对任务目标的知识，要么是具体的(任务集中的)，要么是一般性的(探索性的)。我们发现，在主动和被动条件下，特定意图实验的知觉准确率显著高于一般意图实验。这项工作的成果已经在CogSci2023会议上接受了口头演示和发表。第三，我们开始在类似的环境中设计和试点一个新的形状识别实验。最后，我们几乎完成了对初步入选该项目系统审查部分的文章的全文审查。

Research on active and passive perception in the past year proceeded along several directions.First, we continued the development of research equipment involved in the project. Our first behavioral experiment (described below) highlighted the gaps in implementation that could hinder further progress. Accordingly, we measured and minimized all possible delays between the components of our experimental system such that data can be acquired continuously from movement, haptic output and physiology and synchronized via event triggers.Second, we have completed one behavioral study. Participants explored two-dimensional objects using our experimental apparatus and reported their object size estimates. We manipulated 1) their control over exploratory movements as being either Active (control present) or Passive (control absent) and 2) their knowledge of the task goals, being either Specific (task-focused) or Generic (exploratory). We found no difference between the Active and Passive conditions but significantly higher perceptual accuracy in Specific Intention trials compared to Generic Intention ones. The output of this work has been accepted for oral presentation and publication in the CogSci 2023 conference.Third, we started designing and piloting a new experiment on shape recognition in a similar setup.Finally, we have nearly completed a full text review of articles that were preliminarily selected for the systematic review part of the project.
