ABSTRACT To investigate the relationship between visual acuity and cognitive function with aging, we compared low-vision and normally-sighted young and elderly individuals on a spatial working memory (WM) task. The task required subjects to memorise target locations on different matrices after perceiving them visually or haptically. The haptic modality was included as a control to look at the effect of aging on memory without the confounding effect of visual deficit. Overall, age and visual… Expand
Introducing the Tactual Span: A New Task for Assessing Working Memory in the Teactile Modality
The Tactual Span and other span tasks were found to correlate, while correlations with the selective attention and semantic fluency tasks were largely nonsignificant, indicating good construct validity. Expand
Other ways of seeing: From behavior to neural mechanisms in the online “visual” control of action with sensory substitution
It appears that the use of sensory substitution devices utilizes the neural visual system; this suggests the hypothesis that sensory substitution draws on the same underlying mechanisms as unimpaired visual control of action. Expand
Input, retention, and output factors affecting adult age differences in visuospatial short-term memory.
Results showed that poorer performance by older adults could be attributed independently to reduced visual acuity, to less effective use of rehearsal strategies, and to differences in response biases. Expand
SLAM-based augmented reality for the assessment of short-term spatial memory. A comparative study of visual versus tactile stimuli
A framework for the development of SLAM-based Augmented Reality applications for the assessment of spatial memory is presented and it is suggested that tactile stimuli are valid stimuli to exploit for the Assessment of the ability to memorize spatial-tactile associations, but that the able to memorizing spatial-visual associations is dominant.

Tone discrimination as a window into acoustic perceptual deficits in Parkinson's disease.
It is suggested that persons with PD show a reduced ability to notice change in frequency and amplitude as compared to normal older adults, and this findings implicate a frontal-striatal contribution to auditory perception. Expand
Einfluss visueller Rehabilitation auf sekundäre depressive Störungen bei altersabhängiger Makuladegeneration
The present study examined if visual rehabilitation has a preventive effect on secondary depression in patients with age-related macular degeneration and found positive Auswirkungen auf eine sekundäre Depressivität. Expand


Two-Year Decline in Vision but Not Hearing Is Associated with Memory Decline in Very Old Adults in a Population-Based Sample
The common association between visual acuity, auditory thresholds and cognitive function observed in cross-sectional studies appears to be disassociated in longitudinal studies. Expand
The impact of blurred vision on cognitive assessment
The results are a clear indication of how even a “minimal” loss of visual acuity can have a significant effect on the performance for certain nonverbal tests, and suggests that the precision of the cognitive assessment and subsequent diagnosis are significantly biased when visuo-sensory abilities are not optimal.

The influence of visual experience on the ability to form spatial mental models based on route and survey descriptions
Interestingly, in contrast with sighted people, blind people performed better after listening to a route than a survey description, even when the spatial problems that has to be solved explicitly favor the survey description. Expand
Early Vision Impairs Tactile Perception in the Blind
A critical role of childhood vision is suggested in modulating the perception of touch that may arise from the emergence of specific crossmodal links during development as well as the first empirical evidence for superior temporal order judgments for tactile stimuli in the congenitally blind.

Data indicate that both unimodal modality-specific and higher order supramodal mechanisms are simultaneously used in spatial processes, regardless of the original characteristics of the sensory information. Expand
Age-related deficits in component processes of working memory.
The results suggest that when working memory maintenance systems are taxed, faulty recognition processes may underlie cognitive aging deficits in healthy older individuals. Expand
Intact haptic priming in normal aging and Alzheimer’s disease: evidence for dissociable memory systems
The preservation of intact haptic priming in AD provides strong support to the idea that object implicit memory is mediated by a memory system that is different from the medial-temporal diencephalic system underlying explicit memory, which is impaired early in AD. Expand
Passive Storage and Active Manipulation in Visuo-spatial Working Memory: Further Evidence From the Study of Age Differences
Recent theoretical accounts of working memory proposed a distinction between passive storage and active processing of visuo-spatial information. These hypotheses are based on empirical evidenceExpand
Aging and the Visual, Haptic, and Cross-Modal Perception of Natural Object Shape
Overall, the results of the experiments reveal that older observers can effectively perceive 3-D shape from both vision and haptics. Expand
Why Cyclops could not compete with Ulysses: monocular vision and mental images
The present research demonstrates that the limitations of congenitally blind people in tasks requiring the processing of mental images are specifically related to the absence of binocular vision andExpand
