Successful batters often report that the baseball looked “huge” just before they hit a home run. This effect, dubbed action-specific perception, has been noted for years in all kinds of physical activities.
Yet questions remain about why the illusion happens. Some experts say it is a consequence of imagining the action before you make a move. Others suspect that knowing you nailed it might conjure a larger target in your memory. But a new study in Acta Psychologica suggests neither process alone is enough. Something else is needed: visual attention.
