Abstract

Differently from phenomenological responses, Representational Momentum (RM) offers a continuous response measure in the field of dynamic representations and naïve physics. This property is taken here as a basis for the use of Information Integration Theory in a field where one-dimensional approaches are the rule and integration results are entirely lacking. The present work establishes a psychological multiplying/dividing model in a data pool obtained from a full factorial design Velocity (4) × Traveled Distance (3) with forward displacement error of the last seen position of the target as the measured response. Besides compliance with standard criteria (Anderson, 1982; Weiss, 2006), the model was tested for additional algebraically derived predictions concerning the relations of the intercept c0 to interval and ratio-scale functional measures of the stimuli (Anderson, 1982; Masin, 2004). Implications of the findings are discussed, with an emphasis on estimation of c0, which opens the way to the functional measurement of both stimulus dimensions on a common ratio-scale.
