The most prominent models of numerical representation posit that numerical symbols are converted into a single internal abstract representation prior to estimation and comparison processing. Here, we (1) provide a mathematical analysis of the predictions of the abstract representation hypothesis assuming the validity of the analogue representation hypothesis, (2) run a simulation to assess the pattern of data that results from our mathematical analysis, and (3) conduct two experiments to test the predictions of that model using relative frequencies as inputs. We assess relative frequencies in a typical numerical distance task, whereby the participants are presented two relative frequencies and asked to identify the one that represents the larger quantity. Our data reveal that relative frequencies’ numerical representations (1) are analogue and (2) are scale-specific (i.e., non-abstract).
