What is it about?
Humans develop a very sofisticated set of skills across their development to rapidly integrate instant visual information with action planning. In the current study we investigated whether previous relevant and irrelevant visual cues affected non clinical subjects in their onset velocity to respond to visual targets. Four experiments were conducted to test variations of this premise. We found that the presentation of relevant visual cues related to the response effector (i.e. hands) turned the responses to visual targets faster when compared to irrelevant visual cues (i.e. circles). However this advantage was only observed when the visual cues were spatially compatible to the position of the response effector (e.g. left visual cue + left hand response). Furthermore, when the rate of visual cues presentation was greater than chance (>50%), regarding their spatial compatibility with the visual target onset, the faster were the general responses to the visual targets.

Why is it important?
Such results are important because not only attentional resources may explain how we interact with general surroundings, but previous body representations or body-related stimuli may lead to a faster response to our environment.
Perspectives
I hope this article may be useful for applied settings such as human-machine interaction or human factors in industrial operation. It is not always the case that basic research traslates to applied research, but I believe that such results or experimental design may be tested in applied fields.
