Abstract [en]

Perceived distance between motivationally significant stimuli andobserver has been shown to affect arousal. To study effects ofperceived motion and distance on affective picture processing, eventrelatedpotentials were recorded in two experiments as neutral andunpleasant pictures were presented with different cues to induceperceptions of changes in spatial distance. The cues were either thetarget picture or independent circles that increased or decreased insize, or the target picture presented in a static small or large size. Inboth experiments, late positive potentials at centroparietal electrodeswere more pronounced, and self-reports more negative, forunpleasant compared to neutral stimuli. The results of theexperiments do not, however, provide evidence that inducedperceptions of motion or distance affect late positive potentials.
