“…The hand aperture for the action toward the target assumed the features of the hand aperture related to the object evoked by the olfactory stimulus. The present results are compatible with those obtained in similar experiments in which visual and proprioceptive information from the distractor affected selectively the grasping component of a reach-to-grasp movement (Castiello, 1999;Patchay et al, 2003Patchay et al, , 2005. When the distractor was smaller or bigger than the target, the amplitude of maximum grip aperture was, respectively, smaller or bigger than in the conditions where the size of the distractor was neither taken into account nor altered.…”

“…The investigation of multisensory coding during natural actions is still in its infancy, but recent studies seem to suggest that cross-modal links in motor control are potentially numerous and substantial (Gentilucci et al, 1998;Patchay et al, 2003Patchay et al, , 2005. In these experiments, participants reached and grasped with one hand a visual target of different sizes while holding another unseen object (distractor) of different size in the other hand.…”

Cross-Modal Interactions between Olfaction and Vision When Grasping

This study used kinematics to investigate the integration between vision and olfaction during grasping movements. Participants were requested to smell an odorant and then grasp an object presented in central vision. The results indicate that if the target was small (e.g., a strawberry), the time and amplitude of maximum hand aperture were later and greater, respectively, when the odor evoked a larger object (e.g., an orange) than when the odor evoked an object of a similar size as the target or no odor was presented. Conversely, the time and amplitude of maximum hand aperture were earlier and reduced, respectively, when the target was large (e.g., a peach) and the odor evoked a smaller sized object (e.g., an almond) than when the odor evoked an object of a similar size as the target or no odor was presented. Taken together, these results support the evidence of cross-modal links between olfaction and vision and extend this notion to goal-directed actions.

“…Research on multisensory processing brings evidence of enhancements of multimodal neurons' firings, perceptual processes, or reaction times, in response to stimuli with similar characteristics represented in different modalities [1] , [33] – [36] . More recently, similar enhancements have also been found for prehensile tasks [16] – [18] . For instance, reach-to-grasp movements were faster if two cues related to the same target object pertained to different sensory modalities, i.e., visual and auditory than when only one cue is presented [18] .…”

“…Sufficient time (10 s) was allowed between trials to recover from any odour adaptation [49] . The adopted sequence of events was chosen because previous literature has revealed that effects of task irrelevant information on reach-to-grasp kinematics are maximized when the task irrelevant stimulus/cue (presented in the same or a different sensory modality than the target) is presented slightly before the to-be-grasped target [16] , [31] , [50] . We instructed the subjects to reach at a natural speed and not to grasp the object by the stem.…”

BackgroundResearch on multisensory integration during natural tasks such as reach-to-grasp is still in its infancy. Crossmodal links between vision, proprioception and audition have been identified, but how olfaction contributes to plan and control reach-to-grasp movements has not been decisively shown. We used kinematics to explicitly test the influence of olfactory stimuli on reach-to-grasp movements.Methodology/Principal FindingsSubjects were requested to reach towards and grasp a small or a large visual target (i.e., precision grip, involving the opposition of index finger and thumb for a small size target and a power grip, involving the flexion of all digits around the object for a large target) in the absence or in the presence of an odour evoking either a small or a large object that if grasped would require a precision grip and a whole hand grasp, respectively. When the type of grasp evoked by the odour did not coincide with that for the visual target, interference effects were evident on the kinematics of hand shaping and the level of synergies amongst fingers decreased. When the visual target and the object evoked by the odour required the same type of grasp, facilitation emerged and the intrinsic relations amongst individual fingers were maintained.Conclusions/SignificanceThis study demonstrates that olfactory information contains highly detailed information able to elicit the planning for a reach-to-grasp movement suited to interact with the evoked object. The findings offer a substantial contribution to the current debate about the multisensory nature of the sensorimotor transformations underlying grasping.

An object-centred reference frame for control of grasping: effects of grasping a distractor object on visuomotor control

Previous evidence based on perceptual integration and arbitrary responses suggests extensive cross-modal links in attention across the various modalities. Attention typically shifts to a common location across the modalities, despite the vast differences in their initial coding of space. An issue that remains unclear is whether or not these effects of multisensory coding occur during more natural tasks, such as grasping and manipulating three-dimensional objects. Using kinematic measures, we found strong effects of the diameter of a grasped distractor object on the aperture used to grasp a target object at both coincident and non-coincident locations. These results suggest that interference effects can occur between proprioceptive and visuomotor signals in grasping. Unlike other interference effects in cross-modal attention, these effects do not depend on the spatial relation between target and distractor, but occur within an object-based frame of reference.
