Abstract. 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.

Four experiments examined perceptuo-motor associations involved in spatial knowledge encoding and retrieval. Participants learned spatial information by studying a map or by navigating through a real environment and then verified spatial descriptions based on either egocentric or cardinal directional terms. Participants moved the computer mouse to a YES or NO button to verify each statement. We tracked mouse cursor trajectories to examine perceptuo-motor associations in spatial knowledge. An encoding hypothesis predicts that perceptuo-motor associations depend on the involvement of perceptions and actions during encoding, regardless of how spatial knowledge would be used. The retrieval hypothesis predicts that perceptuo-motor associations change as a function of retrieval demands, regardless of how they are learned. The results supported the retrieval hypothesis. Participants showed action compatibility effects with egocentric retrieval, regardless of how spatial information was learned. With well-developed spatial knowledge, a reliable compatibility effect emerged during egocentric retrieval, but no or limited compatibility effects emerged with cardinal retrieval. With less-developed knowledge, the compatibility effects evident during cardinal retrieval suggest a process of egocentric recoding. Other factors of environment learning, such as location proximity and orientation changes, also impacted the compatibility effect, as revealed in the temporal dynamics of mouse movements. Taken together, the results demonstrate that retrieval demands differentially rely upon perceptuo-motor associations in long-term spatial knowledge. This effect is also modulated by environment experience, proximity of learned locations, and experienced orientations.
