| 520 | _ | _ | |a * Background: Studies on path integration are constrained by the factthat spatial distances are always perceived from the vantage point ofthe body. A spatial distance cannot be perceived per se, but only from the first person perspective. This constraint potentially affects production tasks, in which participants are asked to cover a previouslylearned standard distance, and discrimination tasks, in which participants have to compare the lengths of two travelled paths. However, responses in reproduction tasks are given while the participant ismoving along the path to be estimated, whereas judgments in dis-crimination tasks are required only after both distances have beencompleted.* Aims: It was tested whether distance reproduction and distance dis-crimination are differentially affected by an egocentric coding ofspace.* Method: Using an immersive virtual environment set-up, subjects performed distance discrimination and reproduction tasks. Interfer-ence with egocentric spatial coding was induced by repetitive TMSover the right posterior parietal cortex (PPC).Results: We report differential effects on the two psychophysicaltasks. In distance discrimination, TMS selectively decreased responsevariability, while the mean accuracy of judgments was unaffected. Indistance reproduction, TMS had a selective effect on judgment accuracy, while response variability was not affected.* Conclusions: Errors in distance reproduction do not coincide with judgment accuracy, but rather with altered judgment precision. These results allude to an inherent difference between discrimination and reproduction tasks, which can be traced back to a differential impactof the first person perspective on spatial distance perception. |
