Abstract
We often have to make decisions on the basis of multiple sources of information. Previous work has found that people are able to accurately integrate values presented in Rapid Serial Visual Presentation (RSVP) streams to make an informed judgement of the overall value of the stream (Tsetsos, Chater & Usher, 2012). In this study we investigated whether people’s value judgements can be influenced by salience driven attentional processes. Experiments 1 and 2 examined whether the presentation of irrelevant salient red items in a stream influenced accuracy of the perceived value of the stream. The results showed that an irrelevant high or low value red item led people to judge the stream as having a higher or lower overall value, respectively, compared to when the red item was absent. Experiments 3 and 4 showed that extreme outliers presented in the RSVP stream captured attention automatically, leading to less accurate report of subsequent items in the stream. Taken together the results show that people’s valuations can be swayed by salient items and that outlier items automatically capture attention, leading to over-weighting of extreme values and less accurate judgements of value.
