【摘要】：人類將多種感覺信息有效地合成為統(tǒng)一而穩(wěn)定的知覺。有心理學家(Ernst和Bulthoff)將這種多種感覺信息合成的現(xiàn)象劃為感覺整合與感覺結(jié)合。感覺整合指同維度冗余的感覺信號的合成,相關研究發(fā)現(xiàn)視觸覺整合是線性加和的,通道的線索權(quán)重符合統(tǒng)計最優(yōu)的方法。感覺結(jié)合指跨維度非冗余的感覺信號的合成。視觸覺整合與結(jié)合中的注意機制也受到了研究者的重視。一些研究者發(fā)現(xiàn)視觸覺整合需要消耗注意資源,即整合在注意之后;而另一些研究者發(fā)現(xiàn),視觸覺整合可以提高選擇性注意,消耗注意資源不改變感覺通道權(quán)重,即整合在注意之前。本研究通過操縱被試在接受視觸覺信息時投入于感覺通道的注意程度,探索注意在視觸覺整合與結(jié)合中的作用。實驗一使用視觸覺沖突范式研究注意對視觸覺整合的影響。被試分別在視覺注意、觸覺注意與控制條件下,對一個視覺與觸覺不一致的刺激進行視覺匹配與觸覺匹配。實驗發(fā)現(xiàn),視覺注意條件下的匹配結(jié)果接近視覺刺激,控制條件與觸覺注意條件下的匹配結(jié)果則更偏向觸覺刺激。實驗二與實驗三使用彈性判別任務研究注意對視觸覺結(jié)合的影響。實驗二確定虛擬彈簧的效度,為實驗三提供適合的比較刺激范圍。在實驗三中,以虛擬彈簧為標準刺激,以真實彈簧為比較刺激,用恒定刺激法測量真實彈簧與虛擬彈簧的主觀相等點與最小可覺差。實驗發(fā)現(xiàn),觸覺注意條件下被試的主觀相等點與標準刺激沒有顯著差異,視覺注意條件下被試則低估了真實彈簧的彈性。上述研究結(jié)果表明:注意可以參與到視觸覺整合(同維度)與結(jié)合(跨維度)的過程中,對通道的注意可以調(diào)節(jié)視覺通道與觸覺通道線索的權(quán)重(視觸覺整合)和利用效率(視觸覺結(jié)合),從而改變視觸覺合成后的知覺結(jié)果。
[Abstract]:Human beings effectively synthesize a variety of sensory information into a unified and stable perception. Psychologists (Ernst and Bulthoff) have classified this phenomenon of multiple sensory information synthesis as sensory integration and sensory integration. Sensory integration refers to the synthesis of redundant sensory signals in the same dimension. Related studies have found that visual tactile integration is linearly additive and the clue weight of the channel accords with the statistical optimal method. Sensory association refers to the synthesis of cross-dimensional non-redundant sensory signals. The attention mechanism of visual tactile integration and combination has also been paid attention to by researchers. Some researchers found that visual tactile integration needed to consume attention resources, that is, integration after attention; others found that visual tactile integration could improve selective attention, and that consuming attention resources did not change the weight of sensory channels. Integration is before attention. This study explored the role of attention in the integration and integration of visual tactile by manipulating the participants' attention level in the sensory channel while receiving visual tactile information. Experiment 1 uses the tactile conflict paradigm to study the effects of attention on tactile integration. Under the conditions of visual attention, tactile attention and control, the subjects performed visual matching and tactile matching on a visual and tactile stimulus. It is found that the matching results under visual attention conditions are close to visual stimuli, while those under control and tactile attention conditions are more inclined to tactile stimuli. Experiment 2 and experiment 3 used elastic discriminant task to study the effect of attention on the combination of visual tactile sense. Experiment 2 determines the validity of virtual spring and provides a suitable range of comparative stimuli for experiment 3. In experiment 3, using virtual spring as standard stimulus and real spring as comparison stimulus, the subjective equivalent point and minimum perceptible difference between real spring and virtual spring were measured by constant stimulation method. It was found that there was no significant difference between the subjective equality points and standard stimuli in tactile attention condition, while the elasticity of real spring was underestimated under visual attention condition. The results show that attention can be involved in the process of visual tactile integration (same dimension) and combination (cross-dimensional). Attention to the channel can adjust the weight of visual channel and tactile channel cues (visual tactile integration) and utilization efficiency (visual tactile combination), thus changing the perception results after visual tactile synthesis.
