The Influence Of The Cue Hint Ratio Under Visual Selective Attention On The Number Distance Effect

Visual selective attention is an effective way for us to choose which external information in our life, study and work, it makes us constantly optimize information processing process, and ensure favorable information can be focused and used for us. Since we were born, number plays an indispensable role in the process of growth; digital processing capacity has become one of the important factors that affect our survival and development. Our psychological cognitive process about different visual cue digital stimulations is bound to be affected by the visual selective attention, but how this effect is also need to be further explored. This study combines the technique of behavior experiment and ERP(event-related potentials) hoping to study the influence of visual selective attention and cue hint on the number distance effect. Therefore the experiment one and experiment two use 2(effective cue hint ratio: 75%, 50%) x 2(cue hint effectiveness: valid, invalid) x 4(number distance: 1, 2, 3, and 4) mixed experimental design. In which within subjects factors are cue hint effectiveness and number distance, between subjects factor is effective cue hint ratio. But the experiment one use endogenous cue tips paradigm, the design of experiment two use exogenous cue tips paradigm. The results showed that:(1) Under the condition of the endogenous attention, when effective cue hint ratio is 50%, only number distance had a significant effect on N2 and P3 amplitudes, small number distance induced larger amplitudes; When effective cue hint ratio is 75%, only cue hint effectiveness had a significant effect on N2 and P3 amplitudes, invalid hint induced larger amplitudes.(2) under the condition of the exogenous attention, when effective cue hint ratio is 50%, both cue hint effectiveness and number distance had significant effects on N2 and P3, invalid hint and small number distance induced larger amplitudes on N2 and P3 components; when effective cue hint ratio is 75%, cue hint effectiveness only showed a significant effect on P3 amplitude, number distance had significant effect on N2 and P3 amplitudes, small number distance induced larger amplitudes.
