A deep, enduring emotional bond that connects one person to another across time and space. Attachment theory, developed by John Bowlby and extended by Mary Ainsworth, describes how early caregiver relationships build internal working models — cognitive and emotional templates that shape how individuals seek proximity, respond to threat, and regulate distress across the lifespan.

Ainsworth's Strange Situation procedure identified four infant patterns — secure, anxious-ambivalent, avoidant, and disorganized — that predict but do not determine adult relational behavior. Adult attachment is assessed dimensionally along two axes: anxiety (fear of abandonment) and avoidance (discomfort with closeness). The two- dimensional model replaces the folk notion of fixed "types."

The set of processes — conscious and automatic — by which individuals influence which emotions they have, when they have them, and how they experience and express them. James Gross's process model identifies five regulatory families: situation selection, situation modification, attentional deployment, cognitive change, and response modulation.

The prefrontal cortex (particularly ventromedial and dorsolateral regions) exerts top-down regulation on the amygdala's threat response. Cognitive reappraisal — reinterpreting an event's meaning — is consistently more effective and less costly than suppression, which reduces expressive behavior but increases physiological arousal. Recovery speed after distress (resilience) reflects both trait differences and trainable skills.

The perception of rapid, effortless connection with another person — colloquially called "clicking" — arising from the convergence of multiple psychological and neurological mechanisms that signal compatibility, safety, and mutual engagement. What feels like magic is structurally explainable.

Key mechanisms include behavioral synchrony (unconscious mirroring of gesture, posture, and speech rate), shared attentional focus, mutual vulnerability signaling, and similarity on psychologically meaningful dimensions. Neural coupling — the alignment of brain activity between speaker and attentive listener — predicts how much information is transferred and how well the listener comprehends. The perception of "instant" connection is typically compressed retrospective narration; the actual formation requires a sequence of small, reciprocal risk-taking moments.

A state of emotional and physical exhaustion that results from sustained exposure to others' suffering, combined with a persistent empathic response to that suffering. First described in nursing contexts by Joinson (1992) and formalized by Charles Figley, it is distinguished from burnout by its causal mechanism: not workload per se, but the cumulative cost of empathic engagement with those in pain.

The distinction between empathy and compassion matters here. Empathic distress — affectively mirroring another's negative state — is neurologically costly and associated with withdrawal, vicarious traumatization, and depletion. Compassion — caring about another's suffering without fully taking it on — activates reward circuits and is associated with sustained prosocial motivation. High empathic sensitivity without adequate compassion self-regulation is the vulnerability profile for fatigue.

The deliberate process of attending to and reporting one's own mental states — thoughts, emotions, motivations, and behavioral tendencies. It is the primary method by which people attempt to generate self-knowledge. Its accuracy, however, is significantly and systematically limited by the architecture of the mind it tries to examine.

Much of cognition is unconscious and inaccessible to direct self-report. When people introspect, they typically construct plausible post-hoc narratives rather than retrieving accurate causal records. Nisbett and Wilson (1977) demonstrated that people frequently report reasons for choices that had no causal relationship to the actual choice process. Tasha Eurich's research further distinguishes internal self-awareness (accuracy about one's own states) from external self-awareness (understanding how one appears to others) — the two are largely uncorrelated.
