“…In these conditions, the projection values of ⟨ζ| are no more equally spaced: the first items have a greater distance along the GML. This might explain some behavioral effects, such as those following the Weber's principle formalized as Fechner's law [63,64], giving rise to the well-known primacy effect possibly observed in various serial learning tasks (e.g., in the simultaneous chain task [65,15]).…”

“…This manifold is a line where the arbitrary elements of a sequence can be ranked in any order as suited projections of their neural representations. We derive its analytical form hypothesising it is the so-called 'mental line' capable to solve serial ordering tasks [12,13,14,15]. The proposed 'geometric mental line' (GML) is capable to explain all the behavioral effects observed in Humans and other animals performing an implicit serial learning task, the so-called Transitive Inference (TI) task [16,17].…”

A general mathematical description of the way the brain encodes ordinal knowledge of sequences is still lacking. Coherently with the well-established idea of mixed selectivity in high-dimensional state spaces, we conjectured the existence of a linear solution for serial learning tasks. In this theoretical framework, the neural representation of the items in a sequence are read out as ordered projections along a suited "geometric" mental line learned via classical conditioning (delta rule learning). We show that the derived model explains all the behavioral effects observed in humans and other animal species performing the transitive inference task in presence of noisy sensory information and stochastic neural activity. This result is generalized to the case of recurrent neural networks performing motor decision, where the same geometric mental line is learned showing a tight correlation with the motor plan of the responses. Network activity is then eventually modulated according to the symbolic distance of presented item pairs, as observed in associative cortices of nonhuman primates. Serial ordering is thus predicted to emerge as a linear mapping between sensory input and behavioral output, highlighting a possible pivotal role of motor-related associative cortices in the transitive inference task.

“…Both visual high luminance and loudness have a shared increase in stimulus intensity which is suggested to be encoded by the same brain structure dedicated to magnitude (Lewkowicz & Turkewitz, 1980; Walsh, 2003), This shared feature in neural encoding could serve as the foundation for correspondences based on intensity, such as the pitch‐luminance mapping. If this account is correct, intensity‐based correspondences may be a characteristic common with other species that share the same neural mechanism (Gazes et al, 2023).…”

Humans spontaneously and consistently map information coming from different sensory modalities. Surprisingly, the phylogenetic origin of such cross‐modal correspondences has been under‐investigated. A notable exception is the study of Ludwig et al. (Visuoauditory mappings between high luminance and high pitch are shared by chimpanzees [Pan troglodytes] and humans. Proceedings of the National Academy of Sciences, 108(51), 20661–20665) which reports that both humans and chimpanzees spontaneously map high‐pitched sounds with bright objects and low‐pitched sounds with dark objects. Our pre‐registered study aimed to directly replicate this research on both humans and baboons (Papio papio), an old world monkey which is more phylogenetically distant from humans than chimpanzees. Following Ludwig et al. participants were presented with a visual classification task where they had to sort black and white square (low and high luminance), while background sounds (low or high‐pitched tones) were playing. Whereas we replicated the finding that humans' performance on the visual task was affected by congruency between sound and luminance of the target, we did not find any of those effects on baboons' performance. These results question the presence of a shared cross‐modal pitch‐luminance mapping in other nonhuman primates.
