“…However, several studies have found that performance in recalling the sequential order of visually presented objects is comparable to performance for location recall (van Asselen et al, 2006 ; Delogu, Postma, & Nijboer, 2012 ; Rondina, Curtiss, Meltzer, Barense, & Ryan, 2017 ), and have variously argued that either time or space takes a dominant role in structuring working memory representations. Furthermore, a recent study found evidence that presentation time, like stimulus location, is incidentally encoded in VWM even when it is not task-relevant (Heuer & Rolfs, 2020 ).…”

Spatial location is believed to have a privileged role in binding features held in visual working memory. Supporting this view, Pertzov and Husain (Attention, Perception, & Psychophysics, 76(7), 1914–1924, 2014) reported that recall of bindings between visual features was selectively impaired when items were presented sequentially at the same location compared to sequentially at different locations. We replicated their experiment, but additionally tested whether the observed impairment could be explained by perceptual interference during encoding. Participants viewed four oriented bars in highly discriminable colors presented sequentially either at the same or different locations, and after a brief delay were cued with one color to reproduce the associated orientation. When we used the same timing as the original study, we reproduced its key finding of impaired binding memory in the same-location condition. Critically, however, this effect was significantly modulated by the duration of the inter-stimulus interval, and disappeared if memoranda were presented with longer delays between them. In a second experiment, we tested whether the effect generalized to other visual features, namely reporting of colors cued by stimulus shape. While we found performance deficits in the same-location condition, these did not selectively affect binding memory. We argue that the observed effects are best explained by encoding interference, and that memory for feature binding is not necessarily impaired when memoranda share the same location.

“…Another recent study using a dual-report paradigm did observe some flexibility in the binding mechanism ( Schneegans et al, in press ). In particular, it found that presentation time could take over the role of space in mediating binding between other features when sample items were presented sequentially at the same location, and that a mix of binding strategies may be used when stimuli are separated both in time and space (see also Heuer & Rolfs, 2021 ). However, this study likewise did not find any evidence for object-based representations as basis for feature binding, supporting the view that binding via space is the default mechanism when memorizing simultaneously displayed sample arrays.…”

“…Nonetheless, recall performance in reporting the sequential order of visual stimuli is similar to performance for reporting the objects' locations (Delogu, Postma, & Nijboer, 2012), and both sequential order and location are encoded in working memory automatically even when not task relevant (Heuer & Rolfs, 2021).…”

Previous research on feature binding in visual working memory has supported a privileged role for location in binding an object's non-spatial features. However, humans are able to correctly recall feature conjunctions of objects that occupy the same location at different times. In a series of behavioral experiments, we investigated binding errors under these conditions, and specifically tested whether ordinal position can take the role of location in mediating feature binding. We performed two dual-report experiments in which participants had to memorize three colored shapes presented sequentially at the screen center. When participants were cued with the ordinal position of one item and had to report its shape and color, report errors for the two features were largely uncorrelated. In contrast, when participants were cued e.g. with an item's shape and reported an incorrect ordinal position, they had a high chance of making a corresponding error in the color report. This pattern of error correlations closely matched the predictions of a model in which color and shape are bound to each other only indirectly via an item's ordinal position. In a third experiment, we directly compared the roles of location and sequential position in feature binding. Participants viewed a sequence of colored disks displayed at different locations, and were cued either by a disk's location or its ordinal position to report its remaining properties. The pattern of errors supported a mixed strategy with individual variation, suggesting that binding via either time or space could be used for this task.
