“…Hence, it may be possible that sensitivity for unravelling semantic distance effects induced by the tactile primes differs between experiments. Second, the input-output compatibility (tactile-manual & visual-manual) was higher in the present experiment compared to Rączy and colleagues (tactile-vocal & visual-vocal 21 ). In the context of task switching visual input paired with vocal output leads to higher switch costs compared to visual input paired with manual output 46,47 .…”

“…(p. 215, 48 )". This mechanism may have facilitated the observation of semantic priming effects in the current study and/or obstrued such effects in the study by Rączy et al 21 . Together, these factors may have favored the emergence of semantic priming effects in the current study.…”

“…Our subjects were sighted people that had learned Braille numbers while they were already fluent in recognizing Arabic digits. In a related experiment 21 the same subjects were tested in a behavioral cross-modal priming paradigm where they performed a naming task. Participants were presented with either tactile Braille digits or number words as primes while the targets were visually presented Arabic digits, analogue to the study presented in this paper.…”

“…The participants were students or college graduates with a minimum of 3 years of higher education (mean = 5 range 3-12 years of education). Similar to our previous study 21 the group was recruited from participants of two previous projects, performed in 2016 and 2017, which included a 9-months Braille reading course. During that Braille course, participants acquired tactile recognition of all the Braille letters in the Polish alphabet (for details see 18 ).…”

“…The stimuli were based on Roggeman et al 24 , Reynvoet and Brysbaert 25 , and Reynvoet et al 26 and were identical to those used in our recent behavioral experiment 21 . Following our previous experiment 21 , we excluded the number 1 from the stimuli to avoid the obvious correspondence-one dot = number 1. We used only one-digit numbers from the range 2-6 for the three main reasons: (1) In Braille alphabet numbers are letters preceded by a number indicator.…”

Numbers can be presented in different notations and sensory modalities. It is currently debated to what extent these formats overlap onto a single representation. We asked whether such an overlap exists between symbolic numbers represented in two sensory modalities: Arabic digits and Braille numbers. A unique group of sighted Braille readers underwent extensive Braille reading training and was tested in an fMRI repetition-suppression paradigm with tactile Braille digit primes and visual Arabic digit targets. Our results reveal cross-modal priming: compared to repetition of two different quantities (e.g., Braille “5” and Arabic “2”), repetition of the same quantity presented in two modalities (e.g., Braille “5” and Arabic “5”) led to a reduction of activation in several sub-regions of the Intraparietal Sulcus (IPS), a key cortical region for magnitude processing. Thus, in sighted Braille readers, the representations of numbers read by sight and by touch overlap to a degree sufficient to cause repetition suppression. This effect was modulated by the numerical prime-probe distance. Altogether this indicates that the left parietal cortex hosts neural assemblies that are sensitive to numerical information from different notations (number words or Arabic digits) and modalities (tactile and visual).

Crossmodal transfer of learning is a neurocognitive process whereby a learner's experience and knowledge acquired through one sensory mode enable him/her to perform a similar task using a different sensory mode. This study examined the transfer of (mostly) visually acquired knowledge of first- and second-language characters to the tactile modality typically not used in that acquisition process. Two experiments were conducted, one to assess letter recognition skills and one to assess digit recognition skills in both Bangla and English, in 30 sighted young children who had mastered those characters through sensory learning in natural settings. Results unequivocally demonstrated that children were able to recognize/classify the first and second language letters or digits presented not only to the (trained) visual modality but to the (untrained) tactile modality as well, and as expected, with greater recognition accuracy and shorter recognition time in the former than the latter modality. Their character recognition performance was found to be significantly influenced not by language but by character type, with digits being more accurately and more speedily recognized than letters. Moreover, language–task modality interaction was found to mediate letter recognition accuracy, digit recognition accuracy, and digit recognition time, whereas character type–task modality interaction was found to significantly mediate character recognition time only. The ecological and theoretical significance of these findings is discussed.
