Study Notes
Measurement of Emotions
- Emotional behaviors are observable and a focus of biological research.
- Smiling has positive psychological effects on both the smiler and observers.
- Brain releases dopamine, serotonin, endorphins, and oxytocin when smiling.
- Happiness can boost immunity.
- Even a fake smile reduces stress and lowers heart rate by tricking the brain.
- Smiling is neurologically contagious, activating mirror neurons and encouraging reciprocal smiles.
Mobius Syndrome
- A rare condition resulting from the absence of cranial nerves 6 and 7, leading to facial paralysis.
- Individuals with Mobius Syndrome cannot physically smile yet still experience emotions like happiness and amusement.
Importance of Facial Expressions
- Darwinian perspective states facial expressions evolved to communicate emotions quickly, enhancing social interactions.
- Embodied cognition theories propose that observing facial expressions activates similar emotions in the observer.
- Lack of facial expressions can hinder the understanding of others’ emotions.
De Stefani Study Overview
- Investigated the impact of inability to mimic facial expressions on emotional understanding.
- Rationale: Facial mimicry is essential for recognizing emotional states.
- Observing facial expressions triggers similar neural and physiological responses in observers.
Methods
- Measured autonomic responses and vagal regulation through thermal variations and respiratory sinus arrhythmia.
- Assessed emotional arousal and autonomic response to social cues.
- Compared physiological responses in children with Mobius Syndrome to a control group during face observation.
Results and Conclusions
- Significant differences found between Mobius Syndrome children and control group in physiological responses.
- Mild deficits in emotion recognition were noted in children with the syndrome.
- Supports ‘embodied’ theory, suggesting congenital inability to express emotions affects facial expression processing.
- Suggests risk of emotion dysregulation from inability to produce facial expressions.
