“…Also, the finding of an enlarged MGA indicates an interaction between object perception and action planning. The effect on the grasping kinematics, moreover, parallels research demonstrating effects of size-related semantic information on grasping actions (Gentilucci, Benuzzi, Bertolani, Daprati, & Gangitano, 2000;Glover et al, 2004;Lindemann et al, 2007). Glover et al (2004) have shown that the modulation of the grip aperture by magnitude information reflects interference at the level of action planning.…”

“…Moreover, we observed that the MGA was larger while viewing a large object than while viewing a small object. The object size effect in the grasping kinematics demonstrates an impact of task-irrelevant magnitude information on motor behavior, as has previously been reported for word-reading and numberprocessing tasks Lindemann et al, 2007), and shows that similar effects also emerge during processing of visual 2 A cherry tomato, a tangerine, a carving fork, and a nail were used as sample objects for the training trials. information.…”

“…We expected the time to initiate reaching to be shorter when it was cued by an object affording the same type of grip rather than a different type of grip, that is, an object affordance effect (Tucker & Ellis, 2001). Taking into account previous research showing an impact of semantic magnitude information on grasping kinematics Lindemann, Abolafia, Girardi, & Bekkering, 2007;Lindemann, Stenneken, van Schie, & Bekkering, 2006), we also expected the perceived object size to affect the aperture of the hand during the reaching phase, as revealed by an enlarged MGA for pictures of large as compared with small objects.…”

In 4 experiments, we investigated the effects of object affordance in reach-to-grasp actions. Participants indicated whether a depicted small or large object was natural or manmade by means of different object-grasping responses (i.e., with a power or a precision grip). We observed that the size of the depicted object affected the grasping kinematics (grip aperture) and the reach-onset times of compatible and incompatible actions. Additional experiments showed that the effect of perceived object size on motor response was modulated by contextual action information and the observation of others' actions with the object. Thus, beyond the observation of object affordance effects in natural grasping actions, this study suggests that the coupling between object perception and action is not static and obligatory. Behavioral effects of action-relevant object features seem rather to depend on contextual action information.

“…In addition, bodily states can interplay with action initiation in number tasks. For example, Lindemann, Abolafia, Girardi, and Bekkering (2007) demonstrated that participants' hand grip openings were initiated faster and resulted in wider grip openings when responding to large numbers, compared to smaller grip openings for small numbers.

Though recent work in numerical cognition has supported a strong tie between numerical and spatial representations (e.g., a mental number line), less is known about such ties in multi-digit number representations. Along this line, Bloechle, Huber, and Moeller (2015) found that pointing positions in two-digit number comparison were biased leftward toward the decade digit. Moreover, this bias was reduced in unit-decade incompatible pairs. In the present study, we tracked computer mouse movements as participants compared two-digit numbers to a fixed standard (55). Similar to Bloechle et al. (2015), we found that trajectories exhibited a leftward bias that was reduced for unit-decade incompatible comparisons. However, when positions of response labels were reversed, the biases reversed. That is, we found a rightward bias for compatible pairs that was reduced for incompatible pairs. This result calls into question a purely embodied representation of place value structure and instead supports a competition model of two-digit number representation.

“…Besides number and space interactions, several studies showed that non-spatial kinematic parameters are systematically associated with number. For instance, grip aperture increases when large compared to small numbers are presented prior to the grasping movement (Andres, Davare, Pesenti, Olivier, & Seron, 2004;Andres, Seron, & Olivier, 2007;Chiou, Wu, Tzeng, Hung, & Chang, 2012;Lindemann, Abolafia, Girardi, & Bekkering, 2007). Other studies showed that small numbers are judged faster than large numbers when the response requires closing the index and thumb (precision grip) as for grasping a small object, whereas large numbers are judged faster than small numbers when the response requires opposing the fingers and the palm (whole-hand grip) as for grasping a large object (Chiou, Chang, Tzeng, & Wu, 2009;Moretto & di Pellegrino, 2008).…”

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.
