“…One instance of such overlap-based interaction occurs between the size (volume) of an afforded hand grip and the size (magnitude) of a numerical concept. Indeed, several studies confirmed that participant respond faster when the perceived object’s size corresponds to the perceived number’s magnitude (e.g., Andres et al, 2004, 2008; Lindemann et al, 2007; Moretto and Di Pellegrino, 2008; Ranzini et al, 2011, Gianelli et al, 2012; Namdar et al, 2014; Ranzini et al, 2015; van Dijck et al, 2015). These findings have been extended in other studies to include overlap between non-manipulable object size and numbers (Gabay et al, 2013), weight and numbers (Holmes and Lourenco, 2013), and sound volume and numbers (Heinemann et al, 2013).…”

A crucial question facing cognitive science concerns the nature of conceptual representations as well as the constraints on the interactions between them. One specific question we address in this paper is what makes cross-representational interplay possible? We offer two distinct theoretical scenarios: according to the first scenario, co-activated knowledge representations interact with the help of an interface established between them via congruent activation in a mediating third-party general cognitive mechanism, e.g., attention. According to the second scenario, co-activated knowledge representations interact due to an overlap between their features, for example when they share a magnitude component. First, we make a case for cross-representational interplay based on grounded and situated theories of cognition. Second, we discuss interface-based interactions between distinct (i.e., non-overlapping) knowledge representations. Third, we discuss how co-activated representations may share their architecture via partial overlap. Finally, we outline constraints regarding the flexibility of these proposed mechanisms.

“…Although most studies have examined interactions between numerical information and motor-related spatial coding (e.g., Andres et al, 2004;Andres et al, 2008;Lindemann et al, 2007;Namdar et al, 2014;Namdar and Ganel, 2018;Rugani et al, 2018;Rugani et al, 2017;Badets and Pesenti, 2010;Ranzini et al, 2011), similar interactions have also been observed for other magnitude domains. For example, when participants reached out to grasp a wooden block, their movements had a larger grip aperture after reading a word representing a larger object (e.g.…”

It has been proposed that the brain processes quantities such as space, size, number, and other magnitudes using a common neural metric, and that this common representation system reflects a direct link to motor control, because the integration of spatial, temporal, and other quantity-related information is fundamental for sensorimotor transformation processes. In the present study, we examined compatibility effects between physical stimulus size and spatial (response) location during a sensorimotor task. Participants reached and grasped for a small or large object with either their non-dominant left or their dominant right hand. Our results revealed that participants initiated left hand movements faster when grasping the small cube compared to the large cube, whereas they initiated right hand movements faster when grasping the large cube compared to the small cube. Moreover, the compatibility effect influenced the timing of grip aperture kinematics. These findings indicate that the interaction between object size and response hand affects the planning of grasping movements and supports the notion of a strong link between the cognitive representation of (object) size, spatial (response) parameters, and sensorimotor control.

“…Furthermore, we combined the Stroop conflict and Garner interference (see Section 2.1). Previous research had given the example of the combination of the two tasks (Namdar et al, 2014;Shalev and Algom, 2000), in which the numerical magnitude of the objects affected grip aperture during the initial stages of the grasp. In the current study, two 3-D digits (2, 8) made of polyvinyl chloride (PVC) were used as experimental items.…”

Grasping and Pointing — Visual Conflict and Interference

There have been many debates of the two-visual-systems (whatvs. how or perceptionvs. action) hypothesis that was proposed by Goodale and his colleagues. Many researchers have provided a variety of evidence for or against the hypothesis. For instance, a study performed by Agliotiet al. offered good evidence for the two-visual-systems theory using the Ebbinghaus illusion, but some researchers who used other visual illusions failed to find consistent results. Therefore, we used a perceptual task of conflict or interference to test this hypothesis. If the conflict or interference in perception had an influence on the processing of perception alone and did not affect the processing of action, we could infer that the two visual systems are separated, and vice versa. In the current study, we carried out two experiments which employed the Stroop, Garner and SNARC paradigms and used graspable 3-D Arabic numerals. We aimed to find if the effects resulting from perceptual conflicts or interferences would affect participants’ grasping and pointing. The results showed that the interaction between Stroop and numeral order (ascending or descending, or SNARC) was significant, and the SNARC effect significantly affected action, but the main effects of Stroop and Garner interference were not significant. The results indicated that, to some degree, perceptual conflict affects action processing. The results did not provide evidence for two separate visual systems.
