對426名大學生進行問卷調查,考察了感知環境不確定性對認知變化的影響,環境掃描行為的中介作用以及認知閉合需要與認知需要對兩階段中介模型的調節作用。結果發現:(1)感知環境不確定性能夠正向預測認知變化水平,并且環境掃描行為的兩個維度都起到中介作用;(2)認知閉合需要能夠負向調節中介模型的前后兩個階段;(3)認知需要對環境掃描有直接正向作用,并且對關注程度的促進更大,但是負向調節掃描頻率和認知變化之間的關系。

By investigating 426 undergraduate students, we examined the relationship between Perceived Environmental Uncertainty(PEU) and cognitive change(CC), identified the mediating effect of environmental scanning(ES) and moderating effect of Need for Cognitive Closure(NFCC) and Need for Cognition(NFC). The results indicated that: 1) PEU is positively related to CC and ES serves as a mediator; 2) NFCC can negatively moderate the relationship between PEU and ES; 3) NFC can directly promote ES, but negatively moderate the relationship between ES and CC.
