“…On the other hand, the greater activation of the LH is compatible with studies that found local precedence in the elderly while processing Navon letters (Lux et al, 2008; Oken et al, 1999). A possible account for the seeming contradiction between the excessive reliance on the global shape while processing faces and local-processing precedence while discriminating between Navon hierarchical letters, is that aging entails a reduced cooperation between the hemispheres.…”

“…1 Some studies found an age-related shift from global to local processing precedence (Lux et al, 2008, Oken et al, 1999), and interpreted the relative faster decline of global processing to a narrowed attentional field (cf., Kosslyn et al, 1999). Other studies, however, found preserved global precedence in the normal elderly albeit compared with younger participants, the older participants were overall slower, less accurate (Bruyer and Scailquin, 2000; Bruyer, et al, 2003; Georgiou-Karistianis, et al, 2006 (Experiment 1)), and could not easily switch from one processing level to the other (Georgiou-Karistianis, et al, 2006 (Experiment 2)).…”

We examined the ability of people 70 to 90 years old to apply global, configural and featural faceprocessing strategies. In addition we investigated age-related changes in the ability to categorize faces at basic, subordinate and individual levels. Using the N170 potential as index of early face processing and the P300 component as index of categorical decision making and effort, we found significant age-related perceptual changes which slowed and somewhat impaired face processing. Specifically, older participants had problems integrating face features into global structures, demonstrating enhanced dependence on distal global information. They did not apply configural computations by default while processing faces which suggests that, unless identification is required, they process faces only at a basic level. These perceptual changes could be the cause for slower and less accurate subordinate categorization, particularly when it is based on details. At the neural levels face processing was not right-lateralized, reflecting excessive involvement of the left hemisphere in perception leading to a more general reduction of inter-hemispheric asymmetry. In addition we found excessive but nonselective activation of frontal regions adding support to the view that executive control and particularly inhibition of irrelevant input are reduced in the elderly.Evidence from human (Bian and Andersen, 2008;Fiorentini, et al., 1996;Habak and Faubert, 2000) and monkey research (e.g. Wang, et al., 2005;Zhang, et al., 2008) indicates that, though not dramatically (e.g. Norman, et al., 2008), the efficiency of visual perception declines with age even in healthy individuals. Within this framework age-associated changes in face recognition have been the focus of many studies using performance (e.g. Bartlett and Fulton, 1991;Boutet and Faubert, 2006;Habak, et al., 2008) as well as EEG (e.g. Pfutze, et al., 2002) and hemodynamic neuroimaging (e.g. Grady, 2002;Grady, et al., 2007) methods. Most of these studies revealed reduced face recognition ability in the elderly (e.g. Lott, et al., 2005;Searcy, et al., 1999), even more so than it is evident for object recognition (Boutet © 2010 Elsevier Inc.

Aging in Autism Spectrum Disorders: A Mini-Review

2011

View full text Add to dashboard Cite

This article addresses an important and barely researched topic: what happens to children with autism spectrum disorders when they grow old. We review the small published literature on aging in autism. We then consider the relevance of research on ‘neurotypical’ aging in core domains of autistic impairment: social cognition, executive function, cognitive style and memory. Research themes from the study of normal aging, including cognitive reserve, compensation, quality of life, loneliness and physical health are of relevance for future research on autism. Studies of aging in autism will be important not only to plan appropriate services, but also to shed light on the full developmental trajectory of this neurodevelopmental condition, and perhaps provide clues to neuropathology and etiology.

“…Using a test battery designed to diagnose lateralized brain injury, it has previously been found that the performance of elderly participants is analogous to that of RH damaged patients (Klisz, 1978) and more recently specific RH impairment in elderly participants has been found during performance of a variety of psychophysical tasks (Jenkins et al, 2000; Lux et al, 2008; Nagamatsu et al, 2011; Chokron et al, 2013). The absence or reversal of pseudoneglect presented by elderly participants may therefore reflect general RH decline.…”

A rightward shift in the visuospatial attention vector with healthy aging

The study of lateralized visuospatial attention bias in non-clinical samples has revealed a systematic group-level leftward bias (pseudoneglect), possibly as a consequence of right hemisphere (RH) dominance for visuospatial attention. Pseudoneglect appears to be modulated by age, with a reduced or even reversed bias typically present in elderly participants. It has been suggested that this shift in bias may arise due to disproportionate aging of the RH and/or an increase in complementary functional recruitment of the left hemisphere (LH) for visuospatial processing. In this study, we report rightward shifts in subjective midpoint judgment relative to healthy young participants whilst elderly participants performed a computerized version of the landmark task (in which they had to judge whether a transection mark appeared closer to the right or left end of a line) on three different line lengths. This manipulation of stimulus properties led to a similar behavioral pattern in both the young and the elderly: a rightward shift in subjective midpoint with decreasing line length, which even resulted in a systematic rightward bias in elderly participants for the shortest line length (1.98° of visual angle, VA). Overall performance precision for the task was lower in the elderly participants regardless of line length, suggesting reduced landmark task discrimination sensitivity with healthy aging. This rightward shift in the attentional vector with healthy aging is likely to result from a reduction in RH resources/dominance for attentional processing in elderly participants. The significant rightward bias in the elderly for short lines may even suggest a reversal of hemisphere dominance in favor of the LH/right visual field under specific conditions.
