Would a blind subject, on regaining sight, be able to immediately visually recognize an object previously known only by touch? We addressed this question, first formulated by Molyneux three centuries ago, by working with treatable, congenitally blind individuals. We tested their ability to visually match an object to a haptically sensed sample after sight restoration. We found a lack of immediate transfer, but such cross-modal mappings developed rapidly. 

Cross-Modal Environment Self-Adaptation During Object Recognition in Artificial Cognitive Systems

A cross-modal learning transfer mechanism capable of detecting both sudden and permanent anomalies in the visual channel and still maintain visual object recognition performance by retraining the visual mode for a few minutes using haptic information is created.

1 Quality Spaces and Sensory Modalities

Perhaps nothing in the theoretical study of mind has occasioned more debate than the qualitative character of states such as perceptions, bodily sensations, and emotions. Such qualitative character

Reading the World through the Skin and Ears: A New Perspective on Sensory Substitution

It is shown why the analogy with reading provides a better explanation of the actual findings, that is, both of the positive results achieved and of the limitations noticed across the field of research on sensory substitution.

' s personal copy Transfer of object category knowledge across visual and haptic modalities : Experimental and computational studies

We study people’s abilities to transfer object category knowledge across visual and haptic domains. If a person learns to categorize objects based on inputs from one sensory modality, can the person

Learning to see after early and extended blindness: A scoping review

A structured scoping review of peer-reviewed publications that described the impact of early and extended bilateral visual deprivation on children with delayed access to ocular treatment for blinding conditions suggested persistence in visual acuity, contrast sensitivity, global motion, and visual-motor integration, and suspected concerns for understanding complex objects and faces.

Recalibrating vision-for-action requires years after sight restoration from congenital cataracts

The lack of early pattern vision affects visuomotor recalibration, but this ability is not lost but slowly develops after sight restoration, highlighting the importance of sensorimotor experience gained late in life.

It is argued that the original ability to identify objects across modalities by the neonate may be assured by the same process as that of adaptation to rearrangement in which the experimentally produced separations of seen and felt perceptions of objects are rapidly reunited by the process called capture.

Intermodal matching by human neonates

The experiments reported here show that humans can recognise intermodal matches without the benefit of months of experience in simultaneous tactual–visual exploration, and demonstrate that 29-day-old infants can recognise which of two visually perceived shapes matches one they previously explored tactually, thus supporting the second hypothesis.

Cross-modal transfer of shape is difficult to demonstrate in one-month-olds.

There is not good evidence that 1-month-olds can transfer information about these shapes from touch to vision, and future studies exploring the ability to transfer Information about other shapes will be easier to interpret if they include controls for side bias and stimulus preference.

Childhood blindness in India: a population based perspective

The priorities for action to reduce childhood blindness in India are refractive error, cataract related amblyopia, and corneal diseases.

Visual neuroscience: Look and learn

Prevailing wisdom says the adult brain cannot learn to see if it had no visual stimulation during childhood, but blind people in India seem to be breaking all the rules. Apoorva Mandavilli reports.

The challenge the authors face is to learn enough about the mechanisms of plasticity to modulate them to achieve the best behavioral outcome for a given subject.

Humans integrate visual and haptic information in a statistically optimal fashion

The nervous system seems to combine visual and haptic information in a fashion that is similar to a maximum-likelihood integrator, and this model behaved very similarly to humans in a visual–haptic task.

Visual Parsing After Recovery From Blindness

The results suggest that motion information plays a fundamental role in organizing early visual experience and that parsing skills can be acquired even late in life.

Anatomical Evidence of Multimodal Integration in Primate Striate Cortex

It is shown using retrograde tracers that peripheral area 17 subserving the visual field at an eccentricity of 10–20° receives projections from the core and parabelt areas of the auditory cortex as well as from the polysensory area of the temporal lobe (STP).
