GENDER, N170 EVENT RELATED POTENTIAL, AND IMPLICIT RACIAL BIAS
Title
GENDER, N170 EVENT RELATED POTENTIAL, AND IMPLICIT RACIAL BIAS.
Creator
Heerdegen, Dieter, Anzures, Gizelle, Florida Atlantic University, Department of Psychology, Charles E. Schmidt College of Science
Abstract/Description
To better understand the N170 event related potential (ERP), we examined how factors such as participant gender and implicit racial bias might reflect upon amplitude and latency. White male (18) and female (34) participants performed an implicit association test (IAT) and Simple viewing EEG task with own-race White and other-race Asian faces. We were able to make several conclusions from the data. (1a) Participants generally showed an implicit racial bias favoring their own race group. (1b)...

White male (18) and female (34) participants performed an implicit association test (IAT) and Simple viewing EEG task with own-race White and other-race Asian faces. We were able to make several conclusions from the data. (1a) Participants generally showed an implicit racial bias favoring their own race group. (1b) The degree of this implicit racial bias did not differ between male and female participants. (2) Male, compared to female, participants expressed longer N170 latencies but similar amplitudes. (3) Lower compared to higher levels of implicit racial bias did not appear to influence the N170. (4) Participant gender, stimulus race, and implicit racial bias did not interact to influence the N170.

P100 AND N170 RESPONSES TO RACE: DEVELOPMENT AND RELATIONSHIP WITH CONTACT AND IMPLICIT BIAS

P100 AND N170 RESPONSES TO RACE: DEVELOPMENT AND RELATIONSHIP WITH CONTACT AND IMPLICIT BIAS.

Abstract/Description
Racial bias remains a prevalent issue in society. Clues to the cognitive basis for such biases have been found in EEG studies of the ‘Other Race Effect’ (ORE) in relation to the P100 and N170 event related potentials (ERPs). Previous research in this area has focused on adults, and only one such study has looked at implicit racial biases (He et al., 2009), while only a few have looked at experience with own- and other-race persons (Herzmann et al., 2011; Stahl et al., 2008; Walker et al.,...
Show moreRacial bias remains a prevalent issue in society. Clues to the cognitive basis for such biases have been found in EEG studies of the ‘Other Race Effect’ (ORE) in relation to the P100 and N170 event related potentials (ERPs). Previous research in this area has focused on adults, and only one such study has looked at implicit racial biases (He et al., 2009), while only a few have looked at experience with own- and other-race persons (Herzmann et al., 2011; Stahl et al., 2008; Walker et al., 2008). The present study is the first to examine how race might modulate ERP responses in children, and the first to relate these responses with both implicit racial biases and race contact experience. We examined EEG responses in 5- to 10-year-old children and adults, and whether such responses were associated with implicit racial biases and own- and other-race experience. Results showed that both children and adults displayed larger P100 and N170 responses to other-race faces, greater implicit racial biases related to larger N170 responses to other- than own-race faces, and greater other-race experience related to larger P100 responses to other- than own-race faces. In terms of age differences, we found that compared with adults, children displayed larger and more delayed P100 and N170 responses, and that in children but not in adults, greater experience with own- and other-races were associated with more delayed N170 responses to other- than own-race faces. These findings suggest that age, experience with own- and other-race persons, and implicit racial biases all influence early ERP responses to own- and other-race individuals.

The Dynamics of Implicit Attitudes

The Dynamics of Implicit Attitudes.

Abstract/Description
How do people allocate responsibility for inter-racial conflict (Black vs. White) under ambiguous circumstances? We tested the hypothesis that responsibility allocation reflects people’s implicit racial bias—with greater blame allocated to the Black protagonist by observers with stronger implicit anti-Black bias—but only when they identify the conflict in low-level terms (i.e., the specific momentary actions of the individuals). When observers identify the conflict in high-level terms (e.g.,...
Show moreHow do people allocate responsibility for inter-racial conflict (Black vs. White) under ambiguous circumstances? We tested the hypothesis that responsibility allocation reflects people’s implicit racial bias—with greater blame allocated to the Black protagonist by observers with stronger implicit anti-Black bias—but only when they identify the conflict in low-level terms (i.e., the specific momentary actions of the individuals). When observers identify the conflict in high-level terms (e.g., the intentions of the individuals), they are conscious of their biases and can suppress them in favor of less prejudicial judgments. White and Black participants read or listened to an ambiguous inter-racial conflict narrative, then allocated responsibility for the conflict and rated the protagonists’ personalities. The results showed the defendants were rated as more responsible when rated more positively for personality and affective reaction. Methodological reasons for the direction of the relationship are discussed, as are suggestions for future research.
