Abstract

Research on ensemble encoding has found that viewers
extract summary information from sets of similar items.
When shown a set of four faces of different people,
viewers merge identity information from the exemplars
into a representation of the set average. Here, we
presented sets containing unconstrained images of the
same identity. In response to a subsequent probe,
viewers recognized the exemplars accurately. However,
they also reported having seen a merged average of
these images. Importantly, viewers reported seeing the
matching average of the set (the average of the four
presented images) more often than a nonmatching
average (an average of four other images of the same
identity). These results were consistent for both
simultaneous and sequential presentation of the sets.
Our findings support previous research suggesting that
viewers form representations of both the exemplars and
the set average. Given the unconstrained nature of the
photographs, we also provide further evidence that the
average representation is invariant to several high-level
characteristics.
