This type of stimuli are relatively novel and may reflect the involvement of intelligence in the processing of infrequently encountered faces, such as those of other-ethnicities. Extraversion is associated with increased eye contact which signifies less viewing of diagnostic features for Black faces. Using an old/new recognition paradigm, we found that IQ negatively correlated with the magnitude of the own-ethnicity bias (OEB) and that this relationship was moderated by contact with people from another ethnicity. We interpret these results in terms of IQ enhancing the ability to process novel stimuli by utilising multiple forms of coding. Extraversion was positively correlated with the OEB in White participants and negatively correlated with the OEB in Black participants suggesting that extraverts have lower attention to diagnostic facial features of Black faces, leading to poorer recognition of Black faces in both White and Black participants, thereby contributing to the relative OEB in these participants. The OEB is dependent on participant variables such as intelligence and extraversion. 2019-11 published Bournemouth University 10.18746/bmth.data.00000095 Database bordar@bournemouth.ac.uk Arabaci Hills Peter phills@bournemouth.ac.uk pub submitted Attention Perception and Psychophysics Taken from Hills, Lowe, Hedges, & Teixeira (in press): Participants were all tested individually in a quiet laboratory. After providing informed consent, participants completed Scale 2, Form A of the Cattell's Culture Fair (Cattell & Cattell, 1973) test. The test was administered in accordance with the instructions. Immediately following this, participants completed the face recognition task. This task consisted of three consecutive phases. In the learning phase, participants were shown 40 (20 Black) faces sequentially in a random order. Each face was presented in the centre of the screen. Participants rated these faces on their distinctiveness ("How easy would this face be to spot in a crowd?") using the computer keyboard (Light, Kayra-Stuart & Hollander, 1979). The anchor points for this scale was 1 = "very difficult" and 9 = "very easy." Participants were encouraged to use the numbers in-between. The faces appeared on the screen until the participant responded. Following each face a random noise mask (size 256 x 256 px) was presented in the centre of the screen for 250 ms. On completion of the learning phase, participants completed the IPIP (Goldberg, 1999) and the social contact questionnaire (Walker & Hewstone, 2006). Participants also provided demographic information. Participants responded using the computer keyboard. This task typically took four minutes. The test phase immediately followed this distractor phase. In the test phase, participants were shown all 80 faces sequentially in a random order. Forty faces were old and 40 were new (half Black). Participants responded to each as to whether they had seen the face during the learning phase using the computer keyboard. Participants were instructed to be as fast and as accurate as possible. Each face was shown on the screen until the participant responded. Between each face, there was a random noise mask (size 256 x 256 px) presented in the centre of the screen for 250 ms. On completion of the last trial, participants were thanked and debriefed. 2017 2019
