ABSTRACT

Although previous work provides evidence that observers experience biases in visual processing when they view stimuli in perihand space, a few recent investigations have questioned the reliability of these near-hand effects. We addressed this controversy by running three pre-registered replication experiments. Experiment 1 was a replication of one of the initial studies on facilitated target detection near the hands in which participants performed an attentional cueing task while placing a single hand either near or far from the display. Experiment 2 tested the same paradigm while adopting the design of a recent experiment that called into question near-hand facilitation. Experiment 3 was a replication of a study in which hand proximity influenced working memory performance in a change detection paradigm. Across all three experiments, we found significant interactions between hand position and stimulus characteristics that indicated the hands’ presence altered visual processing, bolstering evidence favouring the robustness of near-hand effects.

摘要

尽管先前的工作提供了证据，表明观察者在观察手掌周围空间的刺激时会在视觉处理过程中遇到偏见，但最近的一些调查质疑了这些手掌附近效应的可靠性。我们通过运行三个预注册的复制实验解决了这一争议。实验1是对手附近的便利目标检测的最初研究之一的重复，其中参与者在将一只手放在显示器附近或远离显示器的同时执行了注意提示任务。实验2测试了相同的范例，同时采用了最近的实验设计，该实验引起了人们对近手辅助的质疑。实验3是一项研究的复制品，其中手的接近度在变化检测范式中影响工作记忆性能。在所有三个实验中，
