This study was designed to evaluate the strength of the relationship between the value of an event and the subjective probability of that event as measured by 3 distinct techniques. A positive relationship was found between these 2 variables under all conditions but diminished in strength as pressures for accuracy increased. The results were discussed in the light of Rotter's criticism of earlier studies. In addition, a comparison was made of the 3 methods of measurement, from which probability ratings emerged as the most reliable technique for studying reactions to objective probability displays.
