| Measure | Time frame |
|---|---|
| Main parameters of interest are the reaction time differences in the visual search tasks, and alterations of perceived stimulus presentation onset. Both can be used as a measure to indicate the degree of influence of VNS on reward processing and selective attention. Previous and ongoing studies on healthy observers in our groups show a beneficial effect of monetary reward on reaction times in visual search tasks (Hickey et al. 2010) and perceived stimulus onset in the simultaneity judgement task. In the present study we aim to test both whether VNS changes these effects of monetary reward and whether stimulation could actually replace the monetary reward as source for the observed influence on selective attention. | — |
