Past research has recognized culture and gender variation in the experience of emotion, yet this has not been examined on a level of effective connectivity. To determine culture and gender differences in effec-tive connectivity during emotional experiences, we applied dynamic causal modeling (DCM) to electro-encephalography (EEG) measures of brain activity obtained from Chinese and American participants while they watched emotion-evoking images. Relative to US participants, Chinese participants favored a model bearing a more integrated dorsolateral prefrontal cortex (dlPFC) during fear v. neutral experiences. Meanwhile, relative to males, females favored a model bearing a less integrated dlPFC during fear v. neutral experiences. A culture-gender interaction for winning models was also observed; only US partici-pants showed an effect of gender, with US females favoring a model bearing a less integrated dlPFC compared to the other groups. These findings suggest that emotion and its neural correlates depend in part on the cultural background and gender of an individual. To our knowledge, this is also the first study to apply both DCM and EEG measures in examining culture-gender interaction and emotion.

Emotion depends on context, culture, and their interaction: Evidence from effective connectivity.
Situated models of emotion hypothesize that emotions are optimized for the context at hand, but most neuroimaging approaches ignore context. For the first time, we applied Granger causality (GC) analysis to determine how an emotion is affected by a person’s cultural background and situation. Electroencephalographic recordings were obtained from mainland Chinese (CHN) and US participants as they viewed and rated fearful and neutral images displaying either social or non-social contexts. Independent component analysis and GC analysis were applied to determine the epoch of peak effect for each condition and to identify sources and sinks among brain regions of interest. We found that source–sink couplings differed across culture, situation and culture × situation. Mainland CHN participants alone showed preference for an early-onset source–sink pairing with the supramarginal gyrus as a causal source, suggesting that, relative to US participants, CHN participants more strongly prioritized a scene’s social aspects in their response to fearful scenes. Our findings suggest that the neural representation of fear indeed varies according to both culture and situation and their interaction in ways that are consistent with norms instilled by cultural background.

Introduction and Theoretical Frameworks Our study draws upon several theoretical foundations to investigate and explain the educational experiences of Black students majoring in ME, CpE, and EE: intersectionality, critical race theory, and community cultural wealth theory. Intersectionality explains how gender operates together with race, not independently, to produce multiple, overlapping forms of discrimination and social inequality (Crenshaw, 1989; Collins, 2013). Critical race theory recognizes the unique experiences of marginalized groups and strives to identify the micro- and macro-institutional sources of discrimination and prejudice (Delgado & Stefancic, 2001). Community cultural wealth integrates an asset-based perspective to our analysis of engineering education to assist in the identification of factors that contribute to the success of engineering students (Yosso, 2005). These three theoretical frameworks are buttressed by our use of Racial Identity Theory, which expands understanding about the significance and meaning associated with students’ sense of group membership. Sellers and colleagues (1997) introduced the Multidimensional Model of Racial Identity (MMRI), in which they indicated that racial identity refers to the “significance and meaning that African Americans place on race in defining themselves” (p. 19). The development of this model was based on the reality that individuals vary greatly in the extent to which they attach meaning to being a member of the Black racial group. Sellers et al. (1997) posited that there are four components of racial identity: 1. Racial salience: “the extent to which one’s race is a relevant part of one’s self-concept at a particular moment or in a particular situation” (p. 24). 2. Racial centrality: “the extent to which a person normatively defines himself or herself with regard to race” (p. 25). 3. Racial regard: “a person’s affective or evaluative judgment of his or her race in terms of positive-negative valence” (p. 26). This element consists of public regard and private regard. 4. Racial ideology: “composed of the individual’s beliefs, opinions and attitudes with respect to the way he or she feels that the members of the race should act” (p. 27). The resulting 56-item inventory, the Multidimensional Inventory of Black Identity (MIBI), provides a robust measure of Black identity that can be used across multiple contexts. Research Questions Our 3-year, mixed-method study of Black students in computer (CpE), electrical (EE) and mechanical engineering (ME) aims to identify institutional policies and practices that contribute to the retention and attrition of Black students in electrical, computer, and mechanical engineering. Our four study institutions include historically Black institutions as well as predominantly white institutions, all of which are in the top 15 nationally in the number of Black engineering graduates. We are using a transformative mixed-methods design to answer the following overarching research questions: 1. Why do Black men and women choose and persist in, or leave, EE, CpE, and ME? 2. What are the academic trajectories of Black men and women in EE, CpE, and ME? 3. In what way do these pathways vary by gender or institution? 4. What institutional policies and practices promote greater retention of Black engineering students? Methods This study of Black students in CpE, EE, and ME reports initial results from in-depth interviews at one HBCU and one PWI. We asked students about a variety of topics, including their sense of belonging on campus and in the major, experiences with discrimination, the impact of race on their experiences, and experiences with microaggressions. For this paper, we draw on two methodological approaches that allowed us to move beyond a traditional, linear approach to in-depth interviews, allowing for more diverse experiences and narratives to emerge. First, we used an identity circle to gain a better understanding of the relative importance to the participants of racial identity, as compared to other identities. The identity circle is a series of three concentric circles, surrounding an “inner core” representing one’s “core self.” Participants were asked to place various identities from a provided list that included demographic, family-related, and school-related identities on the identity circle to reflect the relative importance of the different identities to participants’ current engineering education experiences. Second, participants were asked to complete an 8-item survey which measured the “centrality” of racial identity as defined by Sellers et al. (1997). Following Enders’ (2018) reflection on the MMRI and Nigrescence Theory, we chose to use the measure of racial centrality as it is generally more stable across situations and best “describes the place race holds in the hierarchy of identities an individual possesses and answers the question ‘How important is race to me in my life?’” (p. 518). Participants completed the MIBI items at the end of the interview to allow us to learn more about the participants’ identification with their racial group, to avoid biasing their responses to the Identity Circle, and to avoid potentially creating a stereotype threat at the beginning of the interview. This paper focuses on the results of the MIBI survey and the identity circles to investigate whether these measures were correlated. Recognizing that Blackness (race) is not monolithic, we were interested in knowing the extent to which the participants considered their Black identity as central to their engineering education experiences. Combined with discussion about the identity circles, this approach allowed us to learn more about how other elements of identity may shape the participants’ educational experiences and outcomes and revealed possible differences in how participants may enact various points of their identity. Findings For this paper, we focus on the results for five HBCU students and 27 PWI students who completed the MIBI and identity circle. The overall MIBI average for HBCU students was 43 (out of a possible 56) and the overall MIBI scores ranged from 36-51; the overall MIBI average for the PWI students was 40; the overall MIBI scores for the PWI students ranged from 24-51. Twenty-one students placed race in the inner circle, indicating that race was central to their identity. Five placed race on the second, middle circle; three placed race on the third, outer circle. Three students did not place race on their identity circle. For our cross-case qualitative analysis, we will choose cases across the two institutions that represent low, medium and high MIBI scores and different ranges of centrality of race to identity, as expressed in the identity circles. Our final analysis will include descriptive quotes from these in-depth interviews to further elucidate the significance of race to the participants’ identities and engineering education experiences. The results will provide context for our larger study of a total of 60 Black students in engineering at our four study institutions. Theoretically, our study represents a new application of Racial Identity Theory and will provide a unique opportunity to apply the theories of intersectionality, critical race theory, and community cultural wealth theory. Methodologically, our findings provide insights into the utility of combining our two qualitative research tools, the MIBI centrality scale and the identity circle, to better understand the influence of race on the education experiences of Black students in engineering.more » « less

The number of students with multicultural experiences are growing in the United States. We define multicultural experiences as the multiple cultures that students experience in their early life and through family, which differs from the culture at their higher education institution. Many students immigrate to the US with their families after spending formative years in other countries, which gives them unique perspectives on multiple cultures. Multicultural engineering students have a different understanding of engineering from those without such experiences. These experiences both provide these students with certain advantages in engineering and present challenges in their educational pursuits. Examining both advantages and challenges provides an opportunity to understand these students’ strengths and adaptation strategies. Engineering is a field that requires new thoughts, insights, and opinions to advance. Their meaningful life experiences (particularly their multicultural experiences) can bring new light to issues in engineering as well. The study utilizes data from a larger mixed-methods study of Black students in engineering for in-depth interview transcripts, survey data, and an identity circle artifact. Two cases were purposefully selected for the current study – both participants were raised by African parents and had an additional international experience in a predominantly White country before studying engineering in the US. Both participants used this third point of reference to reflect on and give a rich description of their experience in the US. Through qualitative analysis of these cases, we will address the question: In what ways do Black students who are first- or second-generation immigrants from Africa and have studied abroad leverage community cultural wealth in engineering in the US? We use Yosso’s Community Cultural Wealth (CCW) framework to highlight the strengths these students leverage in engineering. CCW is an asset-based framework developed to highlight the strengths of the students from Communities of Color. There are six assets used as a guiding lens to inform research in these communities: familial, social, aspirational, navigational, resistance, and linguistic capital that students bring from their familial and community background. This framework names and categorizes the numerous skills Students of Color have obtained through lived experiences and how the students are able to be successful in academia. Furthermore, students have the ability to utilize these capitals to their advantage in order to be successful beyond academia. Exploring the CCW of Black immigrant students from African countries will give researchers a better understanding of the assets and strengths these students possess as well as the challenges they face. Through an examination of the CCW and various forms of capital for two Black immigrant students, we will emphasize the strengths of students with multicultural experiences in the hopes that they will be further valued and supported by university administrators.more » « less

Previous research in speech perception has shown that perception is influenced by social factors that can result in behavioral consequences such as reduced intelligibility (i.e., a listeners’ ability to transcribe the speech they hear). However, little is known about these effects regarding Spanish speakers’ perception of heritage Spanish, Spanish spoken by individuals who have an ancestral and cultural connection to the Spanish language. Given that ideologies within the U.S. Latino community often equate Latino identity to speaking Spanish “correctly” and proficiently, there is a clear need to understand the potential influence these ideologies have on speech perception. Using a matched-guised methodology, we analyzed the influence of speaker social background information and listener social background information on speech perception. Participants completed a transcription task in which four different Spanish heritage speakers were paired with different social guises to determine if the speakers were perceived as equally intelligible under each guise condition. The results showed that social guise and listener social variables did not significantly predict intelligibility scores. We argue that the unique socio-political culture within the U.S. Latino community may lead to different effects of language ideology and social expectation on speech perception than what has been documented in previous work.more » « less

Abstract Are children from “Eastern” cultures less emotionally expressive and reactive than children from “Western” cultures? To answer this, we used a multi‐level and multi‐contextual approach to understand variations in emotion displays and cortisol reactivity among preschoolers living in China and the United States. One hundred two preschoolers from China (
N = 58; 55% males) and the United States (N = 44, 48% males) completed three (i.e., control, interpersonal‐related, and achievement‐related) emotion‐challenging paradigms over 3 days. Behavioral emotion expressions were coded, and salivary cortisol was sampled 30 minutes before and across 90 minutes post‐task. Without considering context, Chinese preschoolers displayed fewer levels of positive and negative emotion expressions relative to their United States counterparts. However, Chinese preschoolers displayed similar levels of expressions as their United States counterparts during an achievement‐related challenge that is more salient to their sociocultural emphases and showed higher negative emotion expressions in this challenge, relative to other contexts. Moreover, only the achievement‐related challenge elicited increased cortisol levels among Chinese preschoolers, and this was correlated with higher levels of negative expressions. For US preschoolers, no cortisol increase was observed in any challenging paradigms, nor was cortisol associated with emotional expressions. Findings counter prior notions that East Asian children are generally less emotionally expressive. Instead, an achievement‐related challenge elicited higher emotion expression and cortisol reactivity among Chinese preschoolers, suggesting that children's emotion expression and biological reactivity may be most responsive to contexts salient to their socio‐cultural environments. We discuss the importance of considering cultural contexts when studying emotion regulation.RESEARCH HIGHLIGHTS Chinese preschoolers displayed lower overall positive and negative expressions relative to their US counterparts without considering situational contexts.
Chinese preschoolers displayed similar levels of emotion expressions as their US counterparts during an achievement‐related challenge salient to their social‐cultural environment.
Chinese preschoolers are particularly responsive to achievement‐related challenges, relative to other emotion‐challenging situations that are less culturally salient.
No cortisol increase was observed in any of the emotion‐challenging paradigms among US preschoolers.
Children's emotion expression and biological reactivity may be most responsive to challenges relevant to their socio‐cultural environments.
