“…First, our sample is age-matched with the patient, and thus much older than previously tested populations of healthy subjects. We note that increase in age has been shown to affect multisensory integration and peri-and extrapersonal space representation (Bloesch et al, 2013;Caçola et al, 2013;Ghafouri and Lestienne, 2000;Lepelley et al, 2010;Mahoney et al, 2011). Even if these cited studies included participants older than the present age-matched participants, the findings are in line with the idea that increased age affects the integration of multisensory information.…”

“…The same distortion is not present above the knee because in this body zone the audio feedback of movements isn’t present and multisensory integration is similar to the upper body part where the sensory-motor training with ABBI is useful for spatial recalibration (Finocchietti et al, 2017 ). As regard the spatial areas considered, several studies indicate that space is processed differently depending both: the body part considered (Serino et al, 2015 ; di Pellegrino and Làdavas, 2015 ) and on the distance from the body (Làdavas and Farnè, 2004 ; Aimola et al, 2012 ; Tomasino et al, 2012 ; Caçola et al, 2013 ; Mahayana et al, 2014 ). Other studies have found a difference between frontal and rear space (Kóbor et al, 2006 ; Occelli et al, 2011 ; Van der Stoep et al, 2015 ), showing a higher saliency of sounds in the back (Farnè and Làdavas, 2002 ).…”

Spatial representation is developed thanks to the integration of visual signals with the other senses. It has been shown that the lack of vision compromises the development of some spatial representations. In this study we tested the effect of a new rehabilitation device called ABBI (Audio Bracelet for Blind Interaction) to improve space representation. ABBI produces an audio feedback linked to body movement. Previous studies from our group showed that this device improves the spatial representation of space in early blind adults around the upper part of the body. Here we evaluate whether the audio motor feedback produced by ABBI can also improve audio spatial representation of sighted individuals in the space around the legs. Forty five blindfolded sighted subjects participated in the study, subdivided into three experimental groups. An audio space localization (front-back discrimination) task was performed twice by all groups of subjects before and after different kind of training conditions. A group (experimental) performed an audio-motor training with the ABBI device placed on their foot. Another group (control) performed a free motor activity without audio feedback associated with body movement. The other group (control) passively listened to the ABBI sound moved at foot level by the experimenter without producing any body movement. Results showed that only the experimental group, which performed the training with the audio-motor feedback, showed an improvement in accuracy for sound discrimination. No improvement was observed for the two control groups. These findings suggest that the audio-motor training with ABBI improves audio space perception also in the space around the legs in sighted individuals. This result provides important inputs for the rehabilitation of the space representations in the lower part of the body.

This study examined lifespan characteristics associated with tool use in the modulation of peripersonal and extrapersonal space. Three age groups: Children (7-12 years), Young Adults (19-23 years), and Older Adults (65-92 years) were presented with two experiments using an estimation of reach paradigm involving arm and tool conditions and a switch-block of the opposite condition. Experiment 1 tested Arm and Tool (20 cm length) estimation and switch-block conditions (from Arm to Tool and Tool to Arm) and found a significant effect for Age and Condition (ps <.05). Post-hoc analysis for Age indicated that children were significantly less accurate than young and older adults. Analysis for condition revealed significant differences for the Arm Switch-Block condition (Retraction) when compared to Tool and Arm estimations. Experiment 2 was similar to Experiment 1 with the exception of using a 40 cm length tool. Results were analogous to those found in Experiment 1. Considered together, these results hint that: (1) the ability to be as accurate when estimating reach with a tool and arm is present across the lifespan, (2) development and decline of action representation follow distinct paths, and (3) retraction of space seems to be more difficult than extension.
