A central theoretical assumption in classical psychophysics is that people judge the intensities of stimulus elements; for example, observers directly report the loudness of a tone or the intensity of a shock. A methodological assumption in classical psych ...

Choice is modeled by game theory through analyses of the structure of a game situation. However, at least some choices, such as those in games that have more than one rational solution, are difficult to address under standard game theory. We investigated c ...

In univariate classification tasks, subjects sort stimuli on the basis of the only attribute that varies. In orthogonal classification tasks, often called filtering tasks, there additionally are trial-to-trial variations in irrelevant attributes that the s ...

Palmer describes a 'subjective barrier' that limits knowledge of others' experience. We discuss how this barrier extends to all knowledge, becoming less distinct as theoretical constructs are strengthened. We provide evidence for isomorphic experience, amo ...

We address two major limitations of Schyns et al. First, we
clarify their concept of “features” by postulating several

People cannot make independent judgements of stimulus attributes and so 'it is necessary to theorize in terms of stimulus structures' (Lockhead 1992, p. 551) rather than in terms of stimulus features. The new commentaries here further this statement and al ...

Psychophysical scaling models of the form R = f(I), with R the response and I some intensity of an attribute, all assume that people judge the amounts of an attribute. With simple biases excepted, most also assume that judgments are independent of space, t ...

We propose that the correct interpretation of the moon illusion is that the zenith moon appears small, not that the horizon moon appears large. This illusion is caused by the visual gap between the observer and the overhead moon. Because of the gap, the ob ...

Subjects judge successive stimuli to be overly similar in psychophysical scaling tasks. This is called assimilation. They also tend to judge each stimulus as overly different from more previous events. This is called contrast. To examine a two-stage linear ...
