The spotlight metaphor is useful for understanding how attention is deployed across space.
The P1 was larger contralateral to the cued side, indicating that attention was deployed to the cued location prior to the target onset.
Finally, because attention is deployed not only in space but also in time, the MOT task allows us to test the specificity of learning to trained temporal context.
Thus, plant blindness may result from differences in how attention is deployed to plants.
Moreover, the neural response to an effective distractor was inhibited only when attention was deployed in the same hemifield.
Thus, our result of increased tuning amplitude when attention was deployed to the neuron's RF was predicted.
Conversely, neurons most strongly suppressed by surround stimuli might show the largest activity increase when attention is deployed to the neuron's receptive field (RF).
The results showed strong endogenous and exogenous cueing effects, indicating that participants were faster when attention was deployed to a valid target location.
Critically, when the two stimuli were of equal contrast and attention was deployed to one of them, the cellular response was driven by the attended object in much the same way as it had been by the high-contrast stimulus.
While cleaning up ERP waveforms without producing any phase shifts, which are a characteristic of electronic filters, this band-pass filtering let freely pass only the frequencies lower than 30 Hz, that is, those frequencies, and especially alpha (8 - 15 Hz) and beta (15 - 30 Hz) bands, which have been identified as mechanisms by which selective attention is deployed within vision [ 49- 53].
Here the presence of a uniquely coloured item presented among homogeneous distractors a type of object known in the literature as a colour singleton was found to reduce mutual inhibition in much the same way as occurs when attention is deployed (Kastner et al., 1998).
