visual discrimination task (primary task) and a duration discrimination task (secondary task). We tested various positions both tasks. In one condition the two bars marking the duration, were flashed in two separate locations, in a second condition the two bars were flashed in the same spatial location. We found that shifting attention to perform the primary task can induce a strong compression of temporal intervals. However, this compression of perceived time occurs only if the subject needs to integrate temporal information signalled in two separate locations. Intervals marked in the same spatial position were not subject to such a strong temporal compression and were not affected by attentional deprivation. This indicates that location where the events take place is crucial in determining perceived duration. Taken together, these experiments show that neural representations of space and time are strongly inter-dependent.
