Summary: Recognition accuracy for faces of an individual’s own race typically exceeds recognition accuracy for other-race
faces. The categorization–individuation model (Hugenberg, Young, Bernstein, & Sacco, 2010) attributes this cross-race effect
to motivation to encode distinctive features of own-race faces but category defining features for other-race faces. Two experiments
using different stimuli tested hypotheses generated from this model with both Black and White participants. For White participants,
instructions to individuate reduced the cross-race effect in both studies but did not eliminate it in Study 1. Black participants did
not exhibit the cross-race effect in either study, but individuation instructions improved both their same-race and other-race
sensitivity. The present quality of interracial contact moderated the relationship between instructions and other-race sensitivity
for both Black and White participants in Study 1 but not in Study 2. Overall, results provide mixed support for this social
categorization model. Copyright © 2015 John Wiley & Sons, Ltd.
INTRODUCTION
The Innocence Project (2014) reports that they have helped
exonerate 325 people. Most (72%) of these wrongful
convictions were based on faulty eyewitness identification,
and the majority (53%) of these involved a White witness
misidentifying a Black person. Such errors illustrate the
cross-race effect (CRE; also referred to as other-race effect),
described by Meissner and Brigham (2001) as the reliable
finding that individuals are more accurate in recognizing
and identifying faces of their own race versus faces of
another race. The CRE appears in infancy and progressively
grows stronger through adulthood (e.g., Kelly, Quinn,
Slater, Lee, Ge, & Pascalis, 2007) suggesting both that it
is related to increasing exposure to same-race faces and that
it may prove difficult to overcome.
One common explanation for the CRE is known simply as
the contact hypothesis, which posits that individuals with
greater other-race contact will be more accurate in recogniz-
ing other-race faces (e.g., Jackiw, Arbuthnott, Pfiefer,
Marcon, & Meissner, 2008; Meissner & Brigham, 2001).
Support for the contact hypothesis comes from several stud-
ies reporting significant positive correlations between recog-
nition accuracy for other-race faces and both the quantity and
quality of contact with other-race individuals (e.g., MacLin
& Malpass, 2001; Slone, Brigham, & Meissner, 2000.)
However, the relationship between contact and accuracy in
recognizing other-race faces is fairly weak and inconsistent
across studies (Meissner & Brigham, 2001).
A different explanation for the CRE known as the
categorization–individuation model (CIM) proposes that
there are two different ways of processing faces during
encoding: categorization and individuation. Categorization
requires attending to facial characteristics diagnostic of
category membership; individuation requires attending to
identity diagnostic facial characteristics. The CIM
attributes the CRE to the tendency to selectively attend to
identity-diagnostic characteristics among same-race faces
but to attend to category-diagnostic features of other-race
faces (Hugenberg, Miller, & Claypool, 2007). The CIM
further proposes that everyone has the ability to individuate
other-race faces, but most people are not utilizing this ability.
Greater individuation experience (interracial contact) can trans-
late into superior face memory if combined with motivation to
individuate faces through instructions (Hugenberg, Young,
Bernstein, & Sacco, 2010; Young & Hugenberg, 2012).
In a series of studies directly leading to the present
research, Hugenberg and colleagues (2007) examined
motivational factors that could diminish the CRE in White
participants. They hypothesized that instructions to attend
to the individual features of cross-race faces would increase
individuation thereby leading to improved recognition. In
their first study, Hugenberg and colleagues used either
standard instructions (control) or individuation instructions
explicitly describing the CRE and why it occurs and encour-
aged participants to pay close attention to and to individuate
faces of a different race. Participants in the control group
displayed the typical CRE with greater recognition sensitivity
for own than other-race faces, while the CRE was eliminated
for participants who received the instructions. Furthermore,
general instructions to attend closely to all the faces without
explicitly mentioning the CRE were ineffective.
Recently, Young and Hugenberg (2012) tested their
assumption that interracial contact moderates the effects of
the individuation instructions in White participants. Interra-
cial contact was measured through an interracial contact and
experience scale developed by Hancock and Rhodes (2008)
that was altered to assess the history of contact with Blacks.
As in their prior studies, specific individuation instructions
did reduce the CRE, but more so for participants with higher
levels of interracial contact. In their second study, they found
that high levels of motivation can overcome lower levels of
interracial contact, thus eliminating the CRE. Control partic-
ipants, even those with higher interracial contact, still exhib-
ited the CRE, leading Young and Hugenberg (2012) to
