Knowra Fear Fear Fear is an emotional response to perceived danger that prepares an organism to avoid or escape it. It can arise from immediate threats or anticipated ones.
Amygdala : A group of brain nuclei involved in processing emotional and social information, including threat cues. It helps detect and learn signals associated with danger.
Threat : A condition or event that could cause harm or loss. Fear depends on interpreting something as potentially harmful.
Exposure therapy : A psychological treatment that reduces avoidance by safely confronting feared cues or situations. Repeated, supported encounters can weaken fear-driven avoidance.
Joseph LeDoux : A neuroscientist known for research on emotion, defensive circuits, and fear learning. His work helped establish neural pathways involved in learned defensive responses.
Courage : The capacity to act despite fear, danger, or difficulty. It concerns action in the presence of fear rather than fear’s defensive preparation.
Hypothalamus : A brain region that regulates endocrine, autonomic, and behavioral functions. It coordinates bodily responses that prepare the organism to defend or flee.
Perception : The organization and interpretation of sensory information by an organism. Perceived danger, not danger alone, is central to fear.
Systematic desensitization : A behavioral treatment that pairs gradual exposure to feared stimuli with relaxation training. It applies graded exposure to reduce learned fear.
Robert Rescorla : An American psychologist whose research clarified how animals learn predictive relations between cues and outcomes. His experiments showed that fear learning depends on what a cue predicts.
Disgust : An aversive emotional response that promotes rejection or avoidance of contaminants and other offensive stimuli. Both can motivate avoidance, but disgust centers on rejection rather than danger.
