A Experimental Study On The Attention-orienting Triggered By Visual Subliminal Spatial Cue And Its Applications

Along with the constant improvement of military informatization, the amount and spreading speed of information carried by the modern weapon are both booming, which aggravates the cognitive load for the operation of high-tech weaponry. It has becoming the major obstacle to bring the superiority of new equipment into full play whether this difficult problem on human-computer interaction could be solved smoothly. Thanks to the achievement of unconscious cognitive psychology research, such as subliminal spatial cues, a new way to break the above mentioned barrier is opening up. To blend the principles of subliminal spatial cues into the design of information weapon, it is necessary to study the basic theory about how the attentional orienting will be triggered by subliminal spatial cues in system, to explore a variety of practical factors that may affect the attention effects triggered by subliminal spatial cues by improving psychological experimental paradigm.On the basis of a systematic analysis of related researches home and abroad, this study has defined the basic concepts such as subliminal spatial cues, attentional orientation, etc. analyzed underlying psychological mechanisms and refined the models, improved research paradigm, which laid a solid theoretical foundation for this article; secondly, by using multifactor experimental paradigm of subliminal spatial cues, the parameter of the stimulus are set, the effects of different factors, such as task type, task difficulty, the time interval between stimulus are tested. The results of experimental data analysis and discussion are as follows: firstly, parameter settings of subliminal spatial cue and back mask are consistent under multi-tasking and multi-difficulty conditions; secondly, subliminal spatial cues can trigger exogenous attentional orienting and have an automatic effect on the task performance; thirdly, the attetional effects brought by subliminal spatial cues varies throughout the time interval, which would be affected by the task demand, task type, task difficulty and the nature of subliminal cues.All in all, based on the conclusions of theoretical and experimental analysis, this study proposed how to use subliminal spatial cues to improve the design philosophy of digitalized Human-Computer interface, to innovate and design new warfare display equipment, to refine and improve the military training under conditions of military informatization.
