“…Visual space is furthermore of relevance for neural structures guiding eye movements, such as the FEFs (Bisley, 2011;van der Lubbe, Neggers, Verleger, & Kenemans, 2006;Corbetta, 1998) and the superior colliculus (e.g., Belopolsky & Theeuwes, 2011). Saccade studies provided evidence for an active role of the oculumotor system in STM tasks that involve retrospective selection (Belopolsky & Theeuwes, 2011) as well as attention-based rehearsal (Belopolsky & Theeuwes, 2009b). The overlap between eye movements, spatial attention, and spatial STM in vision is consistent with the notion that these domains rely on common spatial codes (Theeuwes et al, 2009).…”

The focus of attention can be flexibly altered in mnemonic representations of past sensory events. We investigated the neural mechanisms of selection in tactile STM by applying vibrotactile sample stimuli of different intensities to both hands, followed by a symmetrically shaped visual retro-cue. The retro-cue indicated whether the weak or strong sample was relevant for subsequent comparison with a single tactile test stimulus. Locations of tactile stimuli were randomized, and the required response did not depend upon the spatial relation between cued sample and test stimulus. Selection between spatially segregated items in tactile STM was mirrored in lateralized activity following visual retro-cues (N2pc) and influenced encoding of task-irrelevant tactile probe stimuli (N140). Our findings support four major conclusions. First, retrospective selection results in transient shifts of spatial attention. Second, retrospective selection is functionally dissociable from attention-based rehearsal of locations. Third, selection mechanisms are linked across processing stages, as attention shifts in STM influence encoding of sensory signals. Fourth, selection in tactile STM recruits attentional control mechanisms that are, at least partially, supramodal.

“…Along similar lines, Juan, Shorter-Jacobi, and Schall (2004) showed that what is selected by neurons in the frontal eye fields during the allocation of covert spatial attention is different from what is selected during the subsequent preparation of a saccade. Furthermore, a recent study has shown that maintaining covert attention at a location can even be accompanied by a suppression of the oculomotor program (Belopolsky & Theeuwes, 2009). In other words, these studies suggest that attention and eye movements are less tightly coupled than assumed by the premotor theory.…”

Attention and eye movements provide a window into the selective processing of visual information. Evidence suggests that selection is influenced by various factors and is not always under the strategic control of the observer. The aims of this tutorial review are to give a brief introduction to eye movements and attention and to outline the conditions that help determine control. Evidence suggests that the ability to establish control depends on the complexity of the display as well as the point in time at which selection occurs. Stimulusdriven selection is more probable in simple displays than in complex natural scenes, but it critically depends on the timing of the response: Salience determines selection only when responses are triggered quickly following display presentation, and plays no role in longer-latency responses. The time course of selection is also important for the relationship between attention and eye movements. Specifically, attention and eye movements appear to act independently when oculomotor selection is quick, whereas attentional processes are able to influence oculomotor control when saccades are triggered only later in time. This relationship may also be modulated by whether the eye movement is controlled in a voluntary or an involuntary manner. To conclude, we present evidence that shows that visual control is limited in flexibility and that the mechanisms of selection are constrained by context and time.The outcome of visual selection changes with the situational context, and knowing the constraints of control is necessary to understanding when and how visual selection is truly controlled by the observer.

“…According to this model, both domains consist of a passive capacity-limited perceptual store and an active rehearsal mechanism which prevents material-specific information from decaying. For the verbal domain the covert articulatory rehearsal mechanisms, and for the visuospatial domain the motor processes have been initially suggested to serve to hold information in WM (e.g., Baddeley, 1992; Belopolsky and Theeuwes, 2009; Logie, 2011). Consistently, when performed concurrently, many forms of motor actions have been shown to produce interference with the visuospatial domain.…”

Movement Interferes with Visuospatial Working Memory during the Encoding: An ERP Study

The present study focuses on the functional interactions of cognition and manual action control. Particularly, we investigated the neurophysiological correlates of the dual-task costs of a manual-motor task (requiring grasping an object, holding it, and subsequently placing it on a target) for working memory (WM) domains (verbal and visuospatial) and processes (encoding and retrieval). Thirty participants were tested in a cognitive-motor dual-task paradigm, in which a single block (a verbal or visuospatial WM task) was compared with a dual block (concurrent performance of a WM task and a motor task). Event-related potentials (ERPs) were analyzed separately for the encoding and retrieval processes of verbal and visuospatial WM domains both in single and dual blocks. The behavioral analyses show that the motor task interfered with WM and decreased the memory performance. The performance decrease was larger for the visuospatial task compared with the verbal task, i.e., domain-specific memory costs were obtained. The ERP analyses show the domain-specific interference also at the neurophysiological level, which is further process-specific to encoding. That is, comparing the patterns of WM-related ERPs in the single block and dual block, we showed that visuospatial ERPs changed only for the encoding process when a motor task was performed at the same time. Generally, the present study provides evidence for domain- and process-specific interactions of a prepared manual-motor movement with WM (visuospatial domain during the encoding process). This study, therefore, provides an initial neurophysiological characterization of functional interactions of WM and manual actions in a cognitive-motor dual-task setting, and contributes to a better understanding of the neuro-cognitive mechanisms of motor action control.
