摘要
采用知觉负载范式研究颜色和图形的组合图标在不同载荷下的认知机理.通过组合效应实验发现,高载荷下颜色和图形的组合效应不显著,颜色是主要的认知编码.中、低载荷下,颜色和图形的组合效应显著提高了认知绩效.为进一步研究中、低载荷下组合图标中语义对实验结果的影响,在语义实验中将有语义图形转换成无语义倒置图形,发现组合图标中语义显著提高了认知绩效.通过脑电实验更深入地探究组合效应的脑神经机制,发现组合效应提高认知绩效的作用与后颞等脑区相关.研究表明,中、低载荷下组合效应显著提高了认知绩效,其中颜色和语义起关键作用.
The cognitive mechanism of color and graphics combination icons under different loads is studied by perceptual load paradigm.Through the combination effect experiments,it is found that the combination effect of color and graphic is not significant,and color is the main cognitive coding under high load.The combination effect of color and graphic significantly improves cognitive performance under medium and low loads.To understand the impact of semantics in the combined icon on experimental results under medium and low loads,the semantic experiments effectively separates the semantic and visual features in the combined icon by transforming the semantic graph into a non-semantic inverted graph.Findings show that the semantics in the associative effect significantly improves cognitive performance under medium and low loads.The EEG(electroencephalogram)experiments deeply explored the brain nerve mechanism of the combination effect,and found that the combination effect on improving cognitive performance is related to the posterior temporal and other brain areas.The results show that the combination effect under medium and low loads significantly improves cognitive performance,in which color and semantics play a key role.
