Exploring implicit ingroup and outgroup bias toward Hispanics

What is it about?

Racial and ethnic biases often manifest without awareness. The underlying causes of these attitudes are not fully understood. While outgroup bias is well studied, ingroup bias has received far less attention. We examined ingroup biases among Hispanic women and outgroup biases toward Hispanics among White (Caucasian non-Hispanic) females using the startle eyeblink paradigm, the Implicit Association Test (IAT), and an explicit self-report measure. Hispanic and White male faces were used as exemplars during both the startle task and the IAT. A similar pattern of results were observed for indirect measures: both groups displayed startle and IAT responses indicative of negative attitudes toward Hispanic male faces relative to White male faces, although less so for Hispanic participants. Combined groups correlational analyses revealed a significant positive relationship between startle eyeblink amplitude and subtle subscale bias scores. However, no relationships were found between any measures when groups were examined separately. The comparable pattern of startle and IAT results suggests that in spite of the likelihood that these measures index different aspects of attitudes and tap into different processes, inter and intragroup biases are manifested similarly. The finding of negative ingroup biases among Hispanic females is consistent with system justification theory, which posits that members of devalued groups internalize negative stereotypes about their ingroup. This study extends startle eyeblink research of intergroup racial biases, while also expanding this line of research to intragroup biases. In doing so, these results add to our knowledge of the mechanisms underlying the persistent nature of stereotypes.
