    Altruism is defined as costly behavior benefiting others, regardless of intention.

Basic neuroanatomy, specifically the structure and function of the amygdala and the prefrontal cortex in processing emotions.
The psychological distinction between cognitive empathy (understanding another's perspective) and affective empathy (sharing another's emotional state).
Fundamental evolutionary concepts of social behavior, such as kin selection, reciprocal altruism, and the evolutionary origins of cooperation.
An introductory understanding of functional Magnetic Resonance Imaging (fMRI) and how researchers measure brain activity in response to emotional stimuli.
The legal and ethical implications of neuroscientific evidence in the justice system (Neurolaw), specifically regarding moral culpability and psychopathy.
Clinical interventions, therapeutic approaches, and early childhood screening methods designed to address callous-unemotional traits.
The science of neuroplasticity and research on whether empathy and altruistic behavior can be actively trained or enhanced through interventions like compassion meditation.
Advanced study of Abigail Marsh's 'fear-sensitivity' theory, exploring how the brain's response to non-verbal distress cues (like fearful facial expressions) dictates social behavior.

Altruism and psychopathy represent opposite ends of a continuum defined by how much people intrinsically care about others' welfare; altruistic individuals demonstrate heightened neural resonance with others' fear and pain, driven by genuine concern for others' welfare rather than superior empathy abilities, while psychopathic individuals lack the capacity to experience remorse, guilt, and genuine care for others' welfare, making altruism and psychopathy fundamentally rooted in different motivational systems that can be studied together to understand human prosocial behavior.
