“…In contrast, discrete number estimation is still developing and generally more demanding for school children. Moreover, Leibovich and Henik (2013a) suggest that discrete and continuous magnitude processing are two separate, yet interacting systems underlying a general magnitude system (see also Leibovich et al, 2013 ). Similarly, current findings showed a link between both number and space processing, also when controlling for age and/or grade level effects, supporting an interaction between systems.…”

There is strong evidence for a link between numerical and spatial processing. However, whether this association is based on a common general magnitude system is far from conclusive and the impact of development is not yet known. Hence, the present study aimed to investigate the association between discrete non-symbolic number processing (comparison of dot arrays) and continuous spatial processing (comparison of angle sizes) in children between the third and sixth grade (N = 367). Present findings suggest that the processing of comparisons of number of dots or angle are related to each other, but with angle processing developing earlier and being more easily comparable than discrete number representations for children of this age range. Accordingly, results favor the existence of a more complex underlying magnitude system consisting of dissociated but closely interacting representations for continuous and discrete magnitudes.

“…Second, the differences between the compared objects were not equated for physical and conceptual dimensions; pairing a paintbrush with a train, or a camera with a tractor reflected extreme differences in the ratio of conceptual magnitudes, whereas the stimuli’s physical sizes differed roughly in a ratio of 0.5 (i.e., smaller divided by larger size). Given what is known about the influence of ratio effect on congruity (e.g., Leibovich, Diesendruck, Rubinsten & Henik 11 ), such a design might have incresased the saliency of the conceptual dimension in respect to the physical dimension, and thus have enabled the automatic processing of conceptual magnitudes.…”

What is bigger, an elephant or a mouse? This question can be answered without seeing the two animals, since these objects elicit conceptual magnitude. How is an object’s conceptual magnitude processed? It was suggested that conceptual magnitude is automatically processed; namely, irrelevant conceptual magnitude can affect performance when comparing physical magnitudes. The current study further examined this question and aimed to expand the understanding of automaticity of conceptual magnitude. Two different objects were presented and participants were asked to decide which object was larger on the screen (physical magnitude) or in the real world (conceptual magnitude), in separate blocks. By creating congruent (the conceptually larger object was physically larger) and incongruent (the conceptually larger object was physically smaller) pairs of stimuli it was possible to examine the automatic processing of each magnitude. A significant congruity effect was found for both magnitudes. Furthermore, quartile analysis revealed that the congruity was affected similarly by processing time for both magnitudes. These results suggest that the processing of conceptual and physical magnitudes is automatic to the same extent. The results support recent theories suggested that different types of magnitude processing and representation share the same core system.

“…A classical experimental set-up that has been used to demonstrate interference of symbolic and nonsymbolic magnitude information from different dimensions is the number size congruity paradigm (Besner & Coltheart, 1979;Henik & Tzelgov, 1982; for recent studies using this paradigm see e.g., Arend & Henik, 2015;Cohen Kadosh, Henik, & Rubinsten, 2008;Gabay, Leibovich, Henik, & Gronau, 2013;Leibovich et al, 2013;Santens & Verguts, 2011). In this paradigm which is similar to the Stroop task, participants are typically presented with two Arabic digits side by side on a screen.…”

Humans not only process and compare magnitude information such as size, duration, and number perceptually, but they also communicate about these properties using language. In this respect, a relevant class of lexical items are so-called scalar adjectives like ‘big’, ‘long’, ‘loud’, etc. which refer to magnitude information. It has been proposed that humans use an amodal and abstract representation format shared by different dimensions, called the generalized magnitude system (GMS). In this paper, we test the hypothesis that scalar adjectives are symbolic references to GMS representations, and, therefore, GMS gets involved in processing their meaning. Previously, a parallel hypothesis on the relation between number symbols and GMS representations has been tested with the size congruity paradigm. The results of these experiments showed interference between the processing of number symbols and the processing of physical (font-) size. In the first three experiments of the present study (total N=150), we used the size congruity paradigm and the same/different task to look at the potential interaction between physical size magnitude and numerical magnitude expressed by number words. In the subsequent three experiments (total N=149), we looked at a parallel potential interaction between physical size magnitude and scalar adjective meaning. In the size congruity paradigm we observed interference between the processing of the numerical value of number words and the meaning of scalar adjectives, on the one hand, and physical (font-) size, on the other had, when participants had to judge the number words or the adjectives (while ignoring physical size). No interference was obtained for the reverse situation, i.e. when participants judged the physical font size (while ignoring numerical value or meaning). The results of the same/different task for both number words and scalar adjectives strongly suggested that the interference that was observed in the size congruity paradigm was likely due to a response conflict at the decision stage of processing rather than due to the recruitment of GMS representations. Taken together, it can be concluded that the size congruity paradigm does not provide evidence in support the hypothesis that GMS representations are used in the processing of number words or scalar adjectives. Nonetheless, the hypothesis we put forward about scalar adjectives is still is a promising potential line of research. We make a number of suggestions for how this hypothesis can be explored in future studies.
