components of emotion:
1) Biological (neurochemical),
2) Expressive (motor-expressive),
3) Feeling (mental - experiential)
The following extreme position,
put forth by Izzard & Malatesta, is debated in the developmental literature.
Innate emotion-specific facial expressions are regular in form and

The emotional system can function independently of the cognitive system
Biological and social forces change instinctive expressions to more restricted
and controlled emotions
Innate expression-emotion concordance ensures effective communication with
infants. [Does this rule out deception?]
Socialization of expression contributes to regulation of feelings
Emotion feelings are invariant over lifespan but causes and consequences
