A Response Model with a Fixed Number of Successive Observations

Since the k observations are not required to be successive, the demand that model FNOB places on the DM’s processing capability may be too stringent, especially if the DM does not keep a record of the values of the observations already taken or if the observation intervals are very short. This, for example, is the case in the psychophysical experiment to be discussed in Chapter 8. To reduce the DM’s cognitive load, or perhaps better account for the decision rule that some DMs may adopt, the present chapter proposes another decision rule based on a fixed number of successive observations.
