采用四個實驗,通過整體呈現刺激的新范式探究注意在純粹所有權效應發生中的作用。實驗1要求被試在詞表背面寫上自己的名字,結果表現出明顯的純粹所有權效應和積極效應。實驗2不要求被試在詞表背面寫上自己的名字,而是加入觸摸的動作,結果沒有發現純粹所有權效應。實驗3通過"反復交換詞表"從而激發被試更多的注意資源以加強自我與詞表之間的聯系,結果也發現了純粹所有權效應和積極效應。為控制積極效應對純粹所有權效應的影響,實驗4以代表物體名稱的中性名詞作為實驗材料,采用實驗1與實驗3的程序,結果也發現了顯著的純粹所有權效應。結果表明:整體呈現實驗刺激的新范式可以用于探究純粹所有權效應;注意可能是純粹所有權效應的發生機制。

The study applied 4 experiments to investigate the role of attention in the generation of the mere ownership effect(MOE) by using the new paradigm of the holistic presenting stimulus. In experiment 1 the experimenter asked the participants to write down their own names in the back of the word list. The result showed MOE and positive effects. In experiment 2 the experimenter did not ask the participants to write down their own name in the back of word list but asked participants to add the action of touching and the result did not show MOE. Experiment 3 used the action of the experimenter’s "exchanging the word list repeatedly" to inspire participants more attention resources to strengthen the connection between the self and the word list, and the result showed MOE and positive effect. Experiment 4 used neutral nouns with object names as experimental materials to control the influence of positive effect in MOE and adopted the procedure of Experiment 1 and Experiment 3. The result shows obvious MOE. The conclusion is that the new paradigm of presenting stimulus integrally can be used to explore MOE; and attention may be the mechanism of MOE.
