“…The current study builds on previous research and suggests that an age-related decline in object-location binding is not mediated by the presence or absence of visual and geometrical cues (Muffato et al, 2019). The decline in older adults' performance can be explained by age-related functional and morphological changes in the hippocampal circuit (Antonova et al, 2009;Meulenbroek et al, 2004;Moffat et al, 2007), which is crucial for development of spatial memories and manipulation of spatial memories to allow for perspective taking (King et al, 2002) as well as object-location binding (Postma & van der Ham, 2016;Zimmermann & Eschen, 2017).…”

“…The hippocampus may also allow place recognition across different perspectives by enabling the development of viewpoint-independent representations of the environment (Goodrich-Hunsaker & Hopkins, 2010;Hartley, Maguire, Spiers, & Burgess, 2003;Morris, Garrud, Rawlins & O'Keefe, 1982;Wolbers & Büchel, 2005). Furthermore, the hippocampus is involved in objectlocation binding (Zimmermann & Eschen, 2017) and the binding of high-resolution perceptual information, including spatial information (Kolarik et al, 2016), into a single representation (Erez, Lee, & Barense, 2013). Together, these studies demonstrate that the hippocampus plays an important role in development of flexible fine-grained spatial representations and the processes involved in place recognition across different perspectives.…”

Age-related differences in visual encoding and response strategies contribute to spatial memory deficits

et al. 2020

Successful navigation requires memorising and recognising the locations of objects across different perspectives. Although these abilities rely on hippocampal functioning, which is susceptible to degeneration in older adults, little is known about the effects of ageing on encoding and response strategies that are used to recognise spatial configurations. To investigate this, we asked young and older participants to encode the locations of objects in a virtual room shown as a picture on a computer screen. Participants were then shown a second picture of the same room taken from the same (0°) or a different perspective (45°or 135°) and had to judge whether the objects occupied the same or different locations. Overall, older adults had greater difficulty with the task than younger adults although the introduction of a perspective shift between encoding and testing impaired performance in both age groups. Diffusion modelling revealed that older adults adopted a more conservative response strategy, while the analysis of gaze patterns showed an age-related shift in visual-encoding strategies with older adults attending to more information when memorising the positions of objects in space. Overall, results suggest that ageing is associated with declines in spatial processing abilities, with older individuals shifting towards a more conservative decision style and relying more on encoding target object positions using room-based cues compared to younger adults, who focus more on encoding the spatial relationships among object clusters.

“…Instead, it highlights a specific deficit in binding objects to their locations, which could also have contributed to age differences reported in earlier studies. Recent reviews highlight the involvement of the left hippocampus and other related brain areas (such as, bilateral medial temporal lobe, Postma & van der Ham, ; Zimmermann & Eschen, ) in object‐location binding, brain areas that are susceptible to age‐related functional and anatomical changes (Klencklen et al, ).…”

Evidence for age‐related deficits in object‐location binding during place recognition

et al. 2019

Deciding whether a place is the same or different than places encountered previously is a common task in daily navigation which requires to develop knowledge about the locations of objects (object‐location binding) and to recognize places from different perspectives. These abilities rely on hippocampal functioning which is susceptible to increasing age. Thus, the question of the present study is how they both together impact on place recognition in aging. Forty people aged 20–29, 44 aged 60–69, and 32 aged 70–79 were presented with places consisting of four different objects during the encoding phase. In the test phase, they were then presented with a second place and had to decide whether it was the same or different. Test places were presented from different perspectives (0°, 30°, 60°) and with different object conditions (same, a swap of two objects, a substitution with a novel object). The sensitivity for detecting changes (d′) decreased from 20–29 to 60–69 and to 70–79 years old, and with increasing perspective shifts. Importantly, older adults were less sensitive to object swapping than to object substitution, while young participants did not show any difference. Overall, these results suggest specific age‐related difficulties in object‐location binding in the context of place recognition.

“…Kosslyn and colleagues (Kosslyn, 1987;Kosslyn et al, 1989) explicitly conceived visuospatial encoding as the combination of a categorical system providing coarse information for location and a more precise coordinate system (see also Bruyer, Scailquin, & Coibion, 1997;Hellige & Michimata, 1989). This idea has been extended in recent models of memory for object locations (Postma et al, 2004(Postma et al, , 2008 and is supported by dissociations in neuropsychological studies and neuroimaging: Coarse categorical and precise coordinatebased encoding appear to have different neural substrates (see Zimmermann & Eschen, 2017).…”

Charting the Diversity of Strategic Processes in Visuospatial Short-Term Memory

Despite the abundant literature on visuospatial short-term memory, researchers have devoted little attention to strategic processes: What procedures do subjects implement to memorize visuospatial material? Evidence for various strategies exists, but it is spread across a variety of fields. This integrative review of the literature brings together scattered evidence to provide an overview of strategic processes in visuospatial memory tasks. The diversity of strategies and their proposed operating mechanisms are reviewed and discussed. The evidence leads to proposing seven broad strategic processes used in visuospatial short-term memory, each with multiple variants. Strategies can vary across individuals, but the same subjects also appear to use multiple strategies depending on the perceptual features of to-be-remembered displays. These results point to a view of visuospatial strategies as a functional library of facilitatory processes on which subjects can draw to support visuospatial short-term memory performance. Implications are discussed for the difference between visual and spatial tasks, for the appropriate measurement of strategic behaviors, and for the interpretation of performance in visuospatial memory tasks.
