Methodologically, Maslow broke away from nomothetic laboratory experimentation and clinical case studies of neurotics, choosing instead an idiographic, biographical analysis of psychologically healthy historical figures (e.g., Albert Einstein, Eleanor Roosevelt, Abraham Lincoln) and exceptional college students. He termed this psychobiographical approach the studying of peak experiences.
- Peak Experiences (Mihaly Csikszentmihalyi's Flow parallel): Transient moments of profound awe, intense happiness, integration, and self-transcendence where fears and inhibitions are temporarily transcended.
- Deficit vs. Growth Motivation (Neurobiological Correlates): Contemporary affective neuroscience links lower-tier D-needs to subcortical survival circuits (e.g., amygdala, brainstem, dopaminergic reward pathways for immediate reinforcement), whereas B-needs and self-actualization engage higher prefrontal cortical networks associated with abstract integration, executive goal-pursuit, and prosocial empathy.
- Synergy Concept: Borrowed from Ruth Benedict, high social synergy refers to a cultural and psychological state where individual goals align harmoniously with societal welfare, minimizing interpersonal conflict.
