ABSTRACT: In this study, we investigated whether auditory deprivation leads to a more balanced bilateral control of spatial attention in the haptic space. We tested four groups of participants: early deaf, early blind, deafblind, and control (normally hearing and sighted) participants. Using a haptic line bisection task, we found that while normally hearing individuals (even when blind) showed a significant tendency to bisect to the left of the veridical midpoint (i.e., pseudoneglect), deaf individuals did not show any significant directional bias. This was the case of both deaf signers and non-signers, in line with prior findings obtained using a visual line bisection task. Interestingly, deafblind individuals also erred significantly to the left, resembling the pattern of early blind and control participants. Overall, these data critically suggest that deafness induces changes in the hemispheric asymmetry subtending the orientation of spatial attention also in the haptic modality. Moreover, our findings indicate that what counterbalances the right-hemisphere dominance in the control of spatial attention is not the lack of auditory input per se, nor sign language use, but rather the heavier reliance on visual experience induced by early auditory deprivation.

ABSTRACT: The spatial representation of numerical and temporal information is thought to be rooted in our multisensory experiences. Accordingly, we may expect visual or auditory deprivation to affect the way we represent numerical magnitude and time spatially. Here, we systematically review recent findings on how blind and deaf individuals represent abstract concepts such as magnitude and time (e.g., past/future, serial order of events) in a spatial format. Interestingly, available evidence suggests that sensory deprivation does not prevent the spatial "re-mapping" of abstract information, but differences compared to normally sighted and hearing individuals may emerge depending on the specific dimension considered (i.e., numerical magnitude, time as past/future, serial order). Herein we discuss how the study of sensory deprived populations may shed light on the specific, and possibly distinct, mechanisms subserving the spatial representation of these concepts. Furthermore, we pinpoint unresolved issues that need to be addressed by future studies to grasp a full understanding of the spatial representation of abstract information associated with visual and auditory deprivation.

3 Article Deaf Individuals Show a Leftward Bias in Numerical Bisection. 2016

ABSTRACT: Consistent evidence suggests that deaf individuals conceive of numerical magnitude as a left-to-right-oriented mental number line, as typically observed in hearing individuals. When accessing this spatial representation of numbers, normally hearing individuals typically show an attentional bias to the left (pseudoneglect), resembling the attentional bias they show in physical space. Deaf individuals do not show pseudoneglect in representing external space, as assessed by a visual line bisection task. However, whether deaf individuals show attentional biases in representing numerical space has never been investigated before. Here we instructed groups of deaf and hearing individuals to quickly estimate (without calculating) the midpoint of a series of numerical intervals presented in ascending and descending order. Both hearing and deaf individuals were significantly biased toward lower numbers (i.e., the leftward side of the mental number line) in their estimations. Nonetheless, the underestimation bias was smaller in deaf individuals than in the hearing when bisecting pairs of numbers given in descending order. This result may depend on the use of different strategies by deaf and hearing participants or a less pronounced lateralization of deaf individuals in the control of spatial attention.

4 Article Auditory deprivation affects biases of visuospatial attention as measured by line bisection. 2014

Cattaneo, Zaira / Lega, Carlotta / Cecchetto, Carlo / Papagno, Costanza. ·Department of Psychology, University of Milano-Bicocca, Milan, Italy, zaira.cattaneo@unimib.it. ·Exp Brain Res · Pubmed #24770861.

ABSTRACT: In this study, we investigated whether early deafness affects the typical pattern of hemispheric lateralization [i.e., right hemisphere (RH) dominance] in the control of spatial attention. To this aim, deaf signers, deaf non-signers, hearing signers, and hearing non-signers were required to bisect a series of centrally presented visual lines. The directional bisection bias was found to be significantly different between hearing and deaf participants, irrespective of sign language use. Hearing participants (both signers and non-signers) showed a consistent leftward bias, reflecting RH dominance. Conversely, we observed no evidence of a clear directional bias in deaf signers or non-signers (deaf participants overall showing a non-significant tendency to deviate rightward), suggesting that deafness may be associated to a more bilateral hemispheric engagement in visuospatial tasks.
