Adjustment and anchoring heuristic on material presented as animal list

The experiment shows an attempt to answer the question, whether the anchoring eff ect occurs on a material diff erent from the numeral one, in this case, presented as an animal list. Two studies have been conducted, and the participants were university and high school students. First study, utilized visual presentation of a list of animals arranged analogically to Tversky and Kahneman’s experiment (1982). In the second study, previous animals were replaced by new ones and the weight of each has been added. Also, the list has been presented to participants by reading aloud. The results of first study, has not confi rmed the anchoring effect. Although, the second study showed the participants’ decisions were biased. They were affected by anchoring not on the first element of the list but on the last one. The following finding is interpreted as the recency effect.
