Outline of Final Research Achievements

Previous studies already revealed that self-performed actions are remembered better than other-observed actions (SPT effect). Based on the hypotheses that the SPT effect can be seen for actions performed by self-avatar under the condition where participants successfully project themselves on self-avatar, we investigated the factors of temporal and spatial extension of self-actions by measuring how much they remember actions performed by self/other-avatars. Results were that the SPT effect was seen when participants controlled the onset of actions performed by self-avatar and that the SPT effect was not seen even when participants were just instructed that the avatar was "self-avatar" and they observed the actions.
