The belief-based emotion of surprise: The case for a lag in understanding relative to false belief

Three experiments were carried out to determine whether there is a lag in predicting surprise relative to false belief. All 3 experiments used ''backwards reasoning'' tasks. The findings were that(a) there is a lag in predicting surprise relative to false belief, (b) by 5 or 6 years of age children claim that one will be surprised when they gain knowledge of that which they were previously ignorant or when they discover that they had previously held a false belief, (c) by 7 to 9 years of age they understand that surprise will more likely result from false beliefs rather than mere ignorance, and (d) children's difficulty understanding surprise as specifically belief-based does not likely stem from information-processing limitations. It is argued that the lag likely results because children must build a new concept of surprise (e.g., from desire- to belief-based).
