“…These results are in line with previous findings in sequential movement production (Baldauf & Deubel, 2008a;Baldauf et al, 2006;Godijn & Theeuwes, 2003) showing that the discrimination performance at goal positions is superior as compared to irrelevant and intervening positions. The results are evidence for the assumption that several movement-relevant goals are attended by spatially distinct foci, whereas intermediate, movement-irrelevant locations are not selected.…”

Abstract& A dot-probe paradigm was used to provide physiological evidence for the parallel selection of multiple movement goals before rapid hand movement sequences. Participants executed a sequence of manual pointing movements to two out of three possible goal positions. During movement preparation, a taskirrelevant visual transient (a dot probe) was flashed either at one of both movement goals, or at the third, movement-irrelevant location. The results revealed that the N1 component induced by the presentation of the dot was enhanced if the dot was flashed at one of the movement goals, indicating that both target positions were attended before the initialization of the movement sequence. A second experiment showed that movement-irrelevant locations between the movement goals were not attended, suggesting that attention splits into spatially distinct foci. &

“…Similarly, Baldauf and Deubel (2008a) report attentional facilitation at the endpoint of up to three saccades and no facilitation at locations that are irrelevant for the saccade task, even when they lie on the path between two successive fixations. Attentional facilitation can be also observed at multiple saccade goals even when a saccade to only one of the goals is actually executed (Van der Stigchel & Theeuwes, 2005).…”

AbstractSpatial attention and eye-movements are tightly coupled, but the precise nature of this coupling is controversial. The influential but controversial Premotor theory of attention makes four specific predictions about the relationship between motor preparation and spatial attention. Firstly, spatial attention and motor preparation use the same neural substrates. Secondly, spatial attention is functionally equivalent to planning goal directed actions such as eye-movements (i.e. planning an action is both necessary and sufficient for a shift of spatial attention). Thirdly, planning a goal directed action with any effector system is sufficient to trigger a shift of spatial attention. Fourthly, the eye-movement system has a privileged role in orienting visual spatial attention. This article reviews empirical studies that have tested these predictions. Contrary to predictions one and two there is evidence of anatomical and functional dissociations between endogenous spatial attention and motor preparation. However, there is compelling evidence that exogenous attention is reliant on activation of the oculomotor system. With respect to the third prediction, there is correlational evidence that spatial attention is directed to the endpoint of goal-directed actions but no direct evidence that this attention shift is dependent on motor preparation. The few studies to have directly tested the fourth prediction have produced conflicting results, so the extent to which the oculomotor system has a privileged role in spatial attention remains unclear. Overall, the evidence is not consistent with the view that spatial attention is functionally equivalent to motor preparation so the Premotor theory should be rejected, although a limited version of the Premotor theory in which only exogenous attention is dependent on motor preparation may still be tenable. A plausible alternative account is that activity in the motor system contributes to biased competition between different sensory representations with the winner of the competition becoming the attended item.

“…For example, saccades to a remembered location entail a shift of attention from the attended to the remembered location (Hoffman and Subramaniam, 1995;Kowler et al, 1995;Deubel and Schneider, 1996;Baldauf and Deubel, 2008). Multitasking neurons are well situated to facilitate such attention shifts because they are distributed throughout PFdl and thus close to both types of specialized neurons.…”

In motor and sensory areas of cortex, neuronal activity often depends on the location of a movement target or a sensory stimulus, with each neuron tuned to a single part of space called a preferred direction (when motor) or a receptive field (when sensory). As we previously reported, some neurons in the monkey prefrontal cortex are tuned to two parts of space, which we interpreted as reflecting attention and working memory, respectively. Monkeys performed a behavioral task in which they attended to a visual stimulus at one location while remembering a second place, and these locations were varied from trial to trial to assess spatial tuning. Most spatially tuned neurons specialized in either attentional or mnemonic processing, but about one-third of the cells showed tuning for both. Here, we show that the latter population, called multitasking neurons, improves the encoding of both the attended and remembered locations. These neurons do so for three reasons: (1) the preferred directions for attention and for working memory usually differ (and often diametrically oppose one another), (2) they have stronger tuning than specialized cells, and (3) pairs of multitasking neurons represent these cognitive parameters more efficiently than pairs that include even a single specialized cell. These findings suggest that multitasking neurons provide a computational advantage for behaviors that place simultaneous demands on two or more cognitive processes.
