Abstract: | Three experiments provide evidence for a primacy effect in judgments of spatial location. Participants viewed and immediately
estimated a series of spatial locations that were serially ordered from left to right or from right to left. In a subsequent
block, they judged the rightmost, leftmost, and center of the distribution or were shown dots at those locations, which they
then estimated from memory. Both judgments and memories were biased toward locations that had been presented earliest in the
sequence. The findings indicate that participants incorporate not only geometric categories, but also aspects of their prior
spatial experience, when estimating locations. The results mirror recent evidence for a primacy effect in nonspatial category
induction, suggesting that this effect generalizes across domains. |
