“…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.

“…However, this has been demonstrated not to have any clinical bearing to improvement of the condition of AD [62]. Similar findings have also been established in a meta-analysis performed in 1998 [63] and 2002 [64]. This therefore suggests little clinical benefits of Gingko biloba in the management of AD.…”

“…As shown in previous studies, aging, and especially AD, interfere with this process. An increase in localization errors with age [15] and an impairment of global processing with age [16] might increase the need for overt peripheral fi xations. In AD, an additional lengthening of fi xations has been described, enabling the characterization of a more specifi c impairment of visual search in AD patients [5,17] .…”

Visual Search in Patients with Subcortical Vascular Dementia: Short Fixations but Long Reaction Times

Visual search is a cognitive function of high ecological relevance. It involves rapid alternations between allocating and shifting attention. In patients with Alzheimer’s disease, the duration of fixations during visual search increases already in the early stage of the illness. Subcortical vascular dementia (SVD), a newly defined subgroup of vascular dementia, has not yet been examined in this respect. SVD affects patients with a history of lacunar infarctions and/or transient ischemic attacks, focal neurological signs and evidence of subcortical white matter lesions as well as lacunes in the deep grey matter. Here, we report our findings from tracking eye movements during a visual search task with different array sizes in 9 patients with SVD and compare the number and duration of eye fixations they made with the values obtained in 9 healthy elderly control subjects. While patients with SVD were significantly slower in the tasks with longer center to target distances (mean reaction time), the number and duration of fixations they made did not differ from those in controls. Impairment of visual search in patients with SVD seems to be an effect of general cognitive slowing in more demanding arrays of visual search rather than a specific deficit in parameters of eye fixation.
