Can culture and universalism co-exist in affective neuroscience?

The intricate relationship between universal human emotions and the diverse tapestry of cultural influences on personality has long been a cornerstone of psychological inquiry. A recent opinion piece published in Frontiers in Psychology on May 8, 2026, delves into this complex interplay, proposing a framework where foundational affective systems, rooted in our neurobiology, are demonstrably shaped and expressed differently across cultures. This research, building upon Affective Neuroscience Personality Theory (ANPT) and its cross-cultural extension (CAN), argues for a nuanced understanding that embraces both the shared biological underpinnings of emotion and the profound impact of socio-cultural contexts.

The foundation of this research lies in ANPT, which posits that personality traits are epigenetic predictors of fundamental affective systems present in the subcortical regions of the brain. These systems, identified as care, play, seek, anger, sadness, and fear, are not static but are molded by early life experiences and learning, effectively integrating nature and nurture in personality development. The Affective Neuroscience Personality Scale (ANPS) was developed to measure the strength and balance of these systems.

However, the initial ANPT model, while groundbreaking in its holistic approach, largely overlooked the significant influence of cultural diversity. This gap led to the development of Cross-Cultural Affective Neuroscience (CAN), a field dedicated to understanding how cultural factors modulate these universal affective systems. CAN hypothesizes that while the subcortical affective systems themselves are universal, their reinforcement or inhibition is culturally mediated through parenting styles, family structures, emotion socialization practices, and prevailing cultural norms. This perspective positions CAN as a hybrid model, aiming to reconcile universal biological predispositions with culturally specific expressions of emotion and personality.

Unveiling Universal Similarities in Affective Landscapes

The investigation into the co-existence of universalism and cultural specificity in affective neuroscience begins with examining the ANPS through a cross-cultural lens. Standardization studies of the ANPS across numerous languages and cultural contexts, including Spanish, French, Turkish, Norwegian, Italian, Polish, Portuguese, Persian, Japanese, Chinese, German, Serbian, Brazilian Portuguese, and Russian, have provided a robust dataset. These efforts, detailed in various publications and personal communications, have largely confirmed the original reliability and validity findings of the ANPS, originally established in a U.S. context.

A critical aspect of this research is the exploration of construct validity, particularly through correlations with the widely recognized Big Five personality traits (B5S). Across diverse cultural samples such as Spain, Germany, Japan, and Turkey, consistent correlation patterns have been observed. These include positive associations between negative affects (Fear, Sadness, Anger) and neuroticism; a link between high Care, low Anger, and agreeableness; and a correlation between the Seek system and openness to experience. The Play system also consistently correlates with extraversion. These findings suggest a universal mapping between the subcortical affective roots measured by the ANPS and the more cognitively oriented cortical Big Five factors.

A significant meta-analysis conducted by Marengo and colleagues in 2021, encompassing 21 samples from 12 countries, further solidified these universal links. This comprehensive review confirmed the robust relationships between specific affective systems and Big Five traits, providing strong evidence for the fundamental universality of these connections.

Furthermore, CAN research has identified universal gender effects within the ANPS framework. Across 15 countries, it has been consistently observed that females tend to report higher levels of Care and Sadness, while Seeking and Anger levels are generally equivalent between genders. These findings underscore a degree of biological predispositions that transcend cultural boundaries.

Tracing the Threads of Cultural Divergence

Despite the compelling evidence for universal similarities, CAN research has also meticulously documented significant cultural differences in the expression and regulation of these affective systems. The emergence of cultural psychology itself reflects a journey from an initial focus on universalism to a later, more in-depth exploration of cultural variations. This mirrors concerns within cultural neuroscience, which has highlighted the historical overrepresentation of Western samples in neuroimaging studies, leading to potential biases in understanding human cognition and emotion.

Early comparative studies between the U.S. and Turkey, and later between Japan, Turkey, and Germany, revealed notable cultural differences in ANPS profiles. These variations were interpreted as reflections of distinct cultural norms, family models, parenting styles, and emotion socialization practices. For instance, Western cultures, often characterized by individualism and hedonism, tend to reinforce positive affects. In contrast, Eastern cultures, with their emphasis on collectivism and holistic philosophies, may exhibit a tendency to inhibit anger and normalize sadness. German culture, with its purported rationalism, has been observed to show a suppression of most affects. These interpretations, while largely theoretical at this stage, provided a crucial starting point for understanding how cultural frameworks shape emotional experience.

The theoretical underpinnings of these differences often draw upon established cultural dimensions. Concepts such as separation-reinforcing parenting in the West versus symbiotic parenting in the East have been explored, alongside the "separation-without-detachment" style observed in Turkey. While these discussions offer valuable insights, the authors emphasize the need for more empirical methods to validate these theoretical assumptions and to broaden the scope to include diverse caregiving styles, including paternal influences.

Expanding the research beyond bi-cultural comparisons, a large-scale review across 15 countries examining gender effects revealed intriguing geographic variability, particularly in Fear and, to some extent, Play. While Western females often reported higher Fear levels than their male counterparts, this difference was not consistently observed among Eastern females. These findings have been theoretically linked to the influences of individualism and collectivism on neurochemical systems such as oxytocin and serotonin, suggesting a complex interplay between social structures and biological responses.

Moreover, CAN has identified cultural differences in affective polarization and complexity. While positive and negative affects are considered universal higher-order personality factors, some cultures, such as Persian, Turkish, and Japanese samples, exhibit greater intercorrelations between positive and negative affects. This observation aligns with literature suggesting increased affective complexity and dialectical thinking in Eastern cultures, contrasted with affective polarization in Western societies.

Navigating the Landscape of Connectedness and Separateness

To provide a more robust framework for understanding cultural differences, CAN has integrated the assessment of interdependent (connectedness) and independent (separateness) self-construals. These concepts, central to cultural psychology, describe how individuals define themselves in relation to their social groups. While Eastern cultures and females are generally associated with higher connectedness, and Western cultures and males with higher separateness, CAN research has begun to refine these broad categorizations.

Studies integrating ANPS and Big Five Scale (B5S) loadings with self-construals have revealed nuanced patterns. In Japan and Turkey, both ANPS and B5S loaded onto self-construals, whereas in Germany, only the B5S demonstrated this relationship. This suggests that the affective and cognitive underpinnings of self-construal can vary significantly across cultures. For instance, while extraversion is a common predictor of independence across cultures, the specific affective and cognitive mechanisms driving interdependency can differ, indicating that different emotions and cognitions may trigger connectedness and separateness in distinct cultural contexts.

The interplay between culture and gender on self-construals has also been explored. The finding of higher Care and Sadness in females globally is interpreted as aligning with greater attachment and separation distress, and higher relatedness. However, gender differences in both B5 and ANPS scores tend to increase from East to West. The observation that higher Care in females was not found in China and Japan led to discussions about how collectivism (connectedness) and individualism (separateness) might differentially influence gender effects on Care, which inherently requires connectedness.

A particularly striking gender effect relates to Fear. While North American and European females generally report higher Fear than males, this disparity is absent among Asian females. The authors propose that the Eastern philosophy of connectedness may mitigate separation anxiety, which appears to be more pronounced in autonomy-reinforcing individualistic cultures. This hypothesis is supported by neurogenetic research suggesting that collectivism mediates serotonergic and oxytocinergic systems, influencing mood and anxiety. Interestingly, Anger levels, which are associated with disrupting connectedness and activating separateness, did not differ significantly between genders but varied across cultures, highlighting the need for further research into the cultural influences on testosterone.

Future Directions and Implications

While CAN has made significant strides in demonstrating the co-existence of universalism and cultural specificity in affective neuroscience, the authors acknowledge inherent limitations. These include narrow sampling ranges (e.g., age, education, urban/rural comparisons), methodological challenges in defining samples purely by geography, and the potential for measurement invariance issues with the ANPS. Nevertheless, the strong measurement invariance of the ANPS across genders, time, and cultures, as evidenced by the Marengo et al. (2021) meta-analysis, provides a solid foundation for future research.

To advance the field, the authors propose the development of a "global affective map." This map, visualized as heatmaps for each basic affect, differentiated by gender, could be constructed by standardizing ANPS scores across various versions. Such a map would not only illuminate global affective networks and regional similarities but also facilitate the observation of both between- and within-culture variations. It could also help move cross-cultural arguments beyond simplistic East-West dichotomies by incorporating North-South comparisons. The validation of this map would be further strengthened by its correlation with established measures like the Big Five and self-construals.

Crucially, grounding the global affective map and ongoing discussions requires integration with other research fields. Combining ANPS findings with developmental nurture variables, such as breastfeeding duration, toilet training onset, co-sleeping practices, and attachment styles, would provide essential context for how early life experiences shape basic affective systems. Furthermore, a deeper integration of neuroscientific variables, including neuro-anatomical, neuro-functional, and neuro-chemical assessments, would offer a more comprehensive understanding of the "nature" component of CAN.

The evidence presented strongly supports the central hypothesis of CAN: universal affective systems are indeed regulated differently across cultures. This research firmly establishes that universalism and culture can harmoniously co-exist within affective neuroscience, offering a more holistic and nuanced understanding of human personality. The proposed recommendations for methodological improvements and integration with developmental and neuroscientific research promise to further strengthen this nascent but vital theory. Ultimately, these insights hold significant potential for developing culture-sensitive therapeutic interventions, tailoring psychotherapy techniques and goals to the specific cultural contexts of individuals. The ongoing dialogue between universal biological predispositions and the rich diversity of human experience continues to shape our understanding of what it means to be human.
