“…Experiment 2 suggests that the interference of numbers with left-right movements is observed because these responses entail spatial relations that also underlie the coding of numbers with respect to their serial position in WM. More generally, these results validate the use of SRC effects to assess dimensional overlap between cognitive and sensory-motor processes (Fias, Lauwereyns, & Lammertyn, 2001). Previous observations have shown that our ability to grasp an object is overestimated (or underestimated) when the object is preceded by the presentation of small (or large) numbers, whereas such a bias is not observed when the object is preceded by the presentation of the first (or last) letters of the alphabet (Badets, Andres, Di Luca, & Pesenti, 2007).…”

Selective interference of grasp and space representations with number magnitude and serial order processing

It has been proposed that the metrics of space, time and other magnitudes relevant for action are coupled through a generalized magnitude system that also contribute to number representation. Several studies capitalized on stimulusresponse compatibility effects to show that numbers map onto left-right representations and grasp representations as a function of their magnitude. However, the tasks typically used do not allow disentangling magnitude from serial order processing. Here, we devised a working memory (WM) task where participants had to remember random sequences of numbers and perform a precision/whole-hand grip (Experiment 1) or a uni-manual left/right button press (Experiment 2) in response to numbers presented during the retention interval. This task does allow differentiating the interference of number magnitude and serial order with each set of responses. Experiment 1 showed that precision grips were initiated faster than wholehand grips in response to small numbers, irrespective of their serial position in WM. In contrast, Experiment 2 revealed an advantage of right over left button presses as serial position increased, without any influence of number magnitude. These findings demonstrate that grasping and left-right movements overlap with distinct dimensions of number processing. These findings are discussed in the light of different theories explaining the interactions between numbers, space and action.

“…By using a line orientation judgment task (Fias et al, 2001), we found a SNARC-like effect for note values. In Experiment 2 the direction of the spatial association for note values was the opposite of that found in Experiment 1.…”

“…Similarly to Fias, Lauwereyns & Lammertyn (2001), we adopted a line orientation judgment task, since these authors showed that this task is effectively influenced by irrelevant stimuli (i.e., numbers), producing a SNARC effect. Therefore, we expected to obtain similar results with note values, revealing the automaticity of this spatial representation.…”

The SNARC effect is considered an evidence of the association between numbers and space, with faster left key-press responses to small numbers and faster right key-press responses to large numbers. We examined whether visually presented note values produce a SNARClike effect. Differently from numbers, note values are represented as a decreasing left-toright progression, allowing us to disambiguate the contribution of order and magnitude in determining the direction of the effect. Musicians with formal education performed a note value comparison in Experiment 1 (direct task), a line orientation judgment in Experiment 2 (indirect task), and a detection task in Experiment 3 (indirect task). When note values were task relevant (direct task), participants responded faster to large note values with the left key-press, and vice versa. Conversely, when note values were task irrelevant (indirect tasks), the direction of this association was reversed. This evidence suggests the existence of separate mechanisms underlying the SNARC effect. Namely, an Order-Related Mechanism (ORM) and a Magnitude-Related Mechanism (MRM), that are revealed by different task demands. Indeed, according to a new model we proposed, ordinal and magnitude related information seem to be preferentially involved in direct and indirect tasks, respectively.

The authors investigated how 2-digit Arabic numerals are named by looking at the effects of masked primes on the naming latencies. Target numerals were named faster when prime and target shared a digit at the same position (e.g., the target 28 primed by 18 and 21). In contrast, naming latencies were slower when prime and target shared 1 or 2 digits at noncorresponding places (e.g., the target 28 primed by 82, 86, or 72). Subsequent experiments showed that these priming effects were situated at the level of the verbal production of the Arabic numerals. The data point to a nonsemantically mediated route from visual input to verbal output in the naming of 2-digit Arabic numerals.Keywords: naming, two-digit Arabic numerals, masked priming Recent years have witnessed a dramatic increase in the number of studies examining number processing. Unfortunately, for some topics this increase has not been accompanied by a growing consensus about the processes involved. In the current article, we address what arguably should be one of the simplest questions in numerical cognition: How are Arabic numerals named?Four different models have been proposed by various authors, depending on the answers to the following two questions: Is semantic mediation required for the naming of Arabic numerals? Are two-digit numbers processed holistically or through a process of syntactic decomposition into 10s and units?The issue of semantic mediation addresses the question of whether Arabic numerals can be named without first activating their meaning. For visually presented words within an alphabetic language, there is plenty of evidence that such nonsemantically mediated naming is possible. In fact, many existing models of written word naming do not even include an implemented semantic route (e.g., Coltheart, Rastle, Perry, Langdon, & Ziegler, 2001;Plaut, McClelland, Seidenberg, & Patterson, 1996). Such a route is assumed to exist but has not yet been properly examined because it does not seem necessary to account for word-naming latencies. These can be explained by a direct letter-sound conversion route (assembled phonology) or a route in which the visual input activates a presentation in the input lexicon, which, in turn, activates a representation in the phonological output lexicon (addressed phonology).In contrast, most researchers assume that objects and pictures of objects cannot be named without first activating their meaning (e.g., Levelt, Roelofs, & Meyer, 1999). Damian, Vigliocco, and Levelt (2001) provided particularly convincing evidence for the difference between word reading and picture naming. They asked participants to repeatedly name pictures in a semantically homogeneous block (e.g., cat, goat, rat, beaver, tiger, swan) or in a semantically heterogeneous block (e.g., cat, hand, ferry, skirt, broom, leek). Damian et al. observed that participants needed more time to name the pictures in the homogeneous condition than in the heterogeneous condition. They attributed this interference effect to an increased competition in the ret...
