Abstract
Information control is the freedom people equipped to determine the information content, display order, and processing time while they’re searching (Ariely, 2000). However in previous researches, high control could affect people’s decision quality in positive or negative outcome. From the perspective of motivation account, high control brings people responsibility to make correct decisions in order not regretting (Iyengar & Lepper, 2000). But according to cognitive resource theory, people’s decision quality may vary from the capacity of their cognitive resource. Therefore since the behavior of deciding information seeking content, display order, and processing time have taken some resource, then the rest part will affect decision quality. If the rest resource is sufficient to process the information sought, then people’s decision quality will arise (Ariely, 2000; Wu & Lin, 2006). And while the purpose of this research is to justify which of the two theory of control is correct, we implement a new variable which also taken people’s cognitive resource- distraction. If distracted people given high control still perform better than undistracted ones, then the motivation account will be supported. Otherwise the cognitive resource theory should be sustained. And in later analyses, we’ve proved that cognitive resource theory of information control is the correct explanation to the effect on people’s decision quality.
