13.2 Social neuroscience Theory of mid, empathy, mirror neurons and aggression
Theory of mind¶
- Awareness that other individuals have mental states that are different from our own
- Develops in humans around 4-5 years of age
Empathy¶
- ability to share another person's feelings
- Types of empathy feeling
- Personal distress
- when witnessing someone's suffering causes your own discomfort
- Sympathy
- Can feel concern or sorrow for someone but don't about shared feeling like personal distress
- Personal distress
- Cognitive empathy: knowing
- understanding another person's perspective intellectually
Aggression¶
- Definition: behaviour aimed at harming or injuring another living being
- Physical aggression
- Relational aggression
Mirror neurons¶
- Mirror neurons are specialized brain cells that activate both when you perform an action and when you observe someone else performing the same action.
- Activity in some brain areas in MRI study both if a participant experienced pain and if they saw a loved one experience pain
Regarding human studies: - Most human "mirror neuron" research uses fMRI or EEG, which measure broader neural activity rather than individual neurons - We can't directly observe single neuron activity in humans the way researchers did with monkeys - What's often called "mirror system activity" in humans may involve various neural networks
On explaining empathy: - Mirror neurons likely contribute to empathy but aren't sufficient to explain it - Empathy involves multiple processes including emotion regulation, perspective-taking, and contextual understanding - People with autism, sometimes characterized by empathy differences, don't consistently show mirror system deficits
Methodological issues: - Correlational rather than causal evidence dominates the field - Difficult to isolate mirror neuron activity from other neural processes - Risk of reverse inference (assuming mental states from brain activation)
Cause-and-effect questions:
- Does mirror neuron activity cause empathy, or might empathic tendencies enhance mirror system development?
- Individual differences in empathy can't be reduced to mirror neuron function alone
The mirror neuron hypothesis for empathy represents an intriguing but oversimplified explanation for complex social-cognitive abilities that likely involve numerous brain systems working together.
