Final answer:
Facial expressions are subject to culture-specific display rules, though the production and recognition of facial expressions of emotion are largely universal. Ekman's research suggests that certain emotions are associated with distinct universal facial expressions, but cultural norms dictate their display and interpretation.
Step-by-step explanation:
The statement that is most true about cross-cultural observations of facial expressions is that facial expressions are subject to culture-specific display rules. While the ability to recognize and produce facial expressions of emotions appears to be universal, and distinct facial expressions have been associated with seven universal emotions (happiness, surprise, sadness, fright, disgust, contempt, and anger), culture-specific display rules do influence how these expressions are shown and interpreted.
For example, Paul Ekman's research highlights that even isolated cultures have similar facial expressions for certain emotions, suggesting a universal aspect to facial expressions. However, display rules, which dictate the appropriateness of expressing certain emotions, vary across cultures. Similarly, individuals from different cultures may focus on different cues in a social situation, such as context or interpersonal harmony.
It is important to consider that while some aspects of emotion expression are universal, the context in which they are displayed and interpreted can be deeply influenced by cultural norms and values. Therefore, understanding these display rules is critical for accurate cross-cultural communication and interpretation of emotions.
