I remember very clearly the time when Silvan opened my eyes. Each model comprised a dimensional vector coding a composition of facial muscles—one dimension per muscle group, with six parameters coding its temporal dynamics and a set of intensity gradients coding how these dynamics change with perceived intensity Materials and Methods , Model Fitting. As first noted by Darwin in The Expression of the Emotions in Man and Animals 1 , some basic facial expressions originally served an adaptive, biological function such as regulating sensory exposure 2. Spatiotemporal location of emotional intensity representation in Western Caucasian and East Asian culture. However, EA models overlap considerably between emotion categories, demonstrating a different, culture-specific, and therefore not universal, representation of the basic emotions. Wait, are you sad or angry?
If You Are Bad at Reading Facial Expressions, Perhaps This Is Why
Universality did not support his evolutionary theory—for if we all descended from Adam and Eve, expressions would be universal.

Wait, are you sad or angry? The main reason is that pain assessment by facial expression is burdensome. Charles Darwin 6 characterized pain expression thus:.
Darwin's contributions to our understanding of emotional expressions
It is a useful method, but there are many questions that it cannot answer, which must be addressed by measuring facial movement itself see ch. Descriptors are from the system used to code expressions. Cluster analysis and dissimilarity matrices of the Western Caucasian and East Asian models of facial expressions. I'm the author of the national bestselling book Captivate , creator of People School , and human behavioral investigator in our lab. Even so, coding can still consume many multiples of the real time involved in the behaviour. Reply to Sauter and Eisner:
The next wave Identifying relevant facial behaviours and establishing their validity is an important endeavour, but limited as a goal in itself. Fundamentally, this suggests that investigators interested in assessing pain expression can safely limit their attention to these actions without missing information of key importance. Darwin made one more hypothesis about deception: Unlike Schlosberg, who told me he never looked at the faces showed to the judges , Tomkins was fascinated by faces themselves.
