Experimental Studies On The New Model Of Inferencs: The Recognition Heuristic

The Recognition Heuristic inference is a fast-and-frugal strategy for making decisions under conditions of limited knowledge. This strategy is based of recognition capability. It was concerned the most useful decision-making strategies when knowledge was missing, time limited and lake of information. The recognition heuristic mode was first promoted by D.G. Goldstein and G. Gigerenzer hi 2002. Though it's a very young theory, it provokes an endless debate in the psychological field, and soon became the focus on the decision-making strategies. But there isn't any study on this question in China up to now.For the reasons mentioned above, this study adopted "the critical pairs in the universities task" and "the critical pairs in the cities task" and respectively deigned tow researches. The first study adopted the critical pairs in the universities task to examination the frequencies of using Recognition Heuristic inference strategy. The second study adopted the classical experiment's materials "the critical pairs in the cities task" used by Goldstein to examination the frequencies of using Recognition Heuristic inference strategy and to test whether or not there was the "less-is-more effect" effect when we exert pressure on the subjects. There were 36 students as objects in study one, and 40 college students in study tow.We got the following findings in this experimental condition:1. People most use Recognition Heuristic inference strategy when knowledge was missing, time limited and lake of information. And their frequencies are up to the very high level.2. The recognition heuristic is worked in a non-compensatory way.3. Under the conditions of pressures, people still used the Recognition Heuristic inference strategy because lake of knowledge. But it's not fast-and-frugal any more.4. There was the "less-is-more effect" effect when people use the recognition heuristic strategy to make decisions.
