There is a debate about whether working memory (WM) representations are individual features or bound objects. While spatial attention is reported to play a significant role in feature binding, little is known about the role of spatial attention in WM. To address this gap, the current study required participants to maintain multiple items in their WM and employed a memory-driven attention capture paradigm. Spatial attention in WM was manipulated by presenting an exogenous cue at one of the locations that memory items had occupied. The effects of spatial attention on attention guidance in visual search (Experiment 1) and memory performance (Experiments 1 and 2) were explored. The results show that WM-driven attention guidance did not vary based on whether the search features came from the same object in WM; instead, it depended on the number of features, regardless of their source object. In memory tasks, the cued object outperformed the uncued object. Specifically, the test item was better rejected when the features were mis-bound in the cued location than in the uncued location. These findings suggest that memory-driven attention guidance is feature-based, and spatial attention in WM helps bind features into object structures based on location.

“…We chose five highly discriminable colors and five shapes. The five colors were yellow (230,219,38), red (225,20,36), green (44,234,25), fuchsia (224, 0, 233), and cyan (62,230,229). The five shapes were circle, triangle, diamond, pentagon, and hexagon.…”

“…It is also clear that representations held in memory can influence spatial attention, and in turn that information held in memory can guide spatial attention, even when the former simply provides a context to the task at hand (e.g. Kim, Kim & Chun, 2010) or it is subliminally presented (Astle, Nobre & Scerif, 2010). Dixon, Zelazo and De Rosa (2010) examined the performance of 5‐ to 9‐year‐olds on an age‐appropriate version of the contextual cueing paradigm (e.g.…”

Attentional processes play a crucial role in prioritizing information for further processing and they therefore sit at the interface between internal goals and the challenges presented by the environment. How does attentional control interact with the changing constraints imposed by the developing cognitive system? Emerging work in this area has employed a range of complementary techniques, from increasingly refined neurocognitive measures in typically developing individuals, to the investigation of risk or protective factors influencing attention trajectories in developmental disorders. A growing corpus of data suggests that, while attentional biases for specific input characteristics (e.g. suddenly appearing stimuli, emotional expressions) are in place from infancy, it is the interplay between these predispositions, genetic and environmental factors that drives attention development over time. With the advent of multidisciplinary approaches to the developmental cognitive neuroscience of attention, unravelling these complex dynamics from infancy and their outcome on learning is increasingly within reach.

“…On the basis of this distinction, earlier studies have suggested that spatial and nonspatial representations in VWM are processed by separate mechanisms and can have distinct influences on search behavior (J. J. Kim, Kim, & Chun, 2010;S.-Y. Kim, Kim, & Chun, 2005;Oh & Kim, 2004;Woodman & Luck, 2004;Woodman, Vogel, & Luck, 2001).…”

Exploring the contributions of spatial and non-spatial working memory to priming of pop-out

Priming of pop-out (PoP) refers to the facilitation of performance that occurs when a target-defining feature is repeated across consecutive trials in a pop-out oddball search task. The underlying mechanism of PoP has been poorly understood and raises important questions about how our visual system is guided by past experiences, even during bottom-up processing. Lee, Mozer, and Vecera (Attention, Perception, & Psychophysics, 71, 1059-1071, 2009) demonstrated that PoP remained unaffected by a concurrent non-spatial visual working memory (VWM) load, and they concluded that PoP occurs through feature gain modulation, essentially eliminating the contribution of memory representations in VWM to PoP. In the present study, we followed up on those results by (a) replicating the null effect of non-spatial VWM load on PoP and (b) examining the effect of spatial VWM load on PoP. The results showed that spatial VWM load does interfere with PoP, supporting the notion that spatial VWM is involved in PoP. In Experiment 2, we extended this finding by manipulating VWM load and observing its consequence on the magnitude of PoP. Increasing spatial VWM load decreased the amount of PoP observed, in a dose-dependent manner, whereas changes in non-spatial VWM load did not. Contrary to Lee et al.'s conclusions, these results suggest that VWM resources appear to contribute to the occurrence of PoP, supporting the theory that PoP is, in fact, a multilevel process in which the deployment of spatial attention, relying on VWM representations, plays an important role.
