Coined by psychologist Dorothy Tennov in 1979, limerence differs from love due to its compulsive and often one-sided nature.It’s more common in individuals...
Summary: Psychology has been instrumental in the evolution of artificial intelligence, offering foundational insights into learning, cognition, and behavior that have shaped key AI technologies. From early neural networks based on Hebbian learning to modern deep learning and metacognition, psychological theories continue to inform AI’s development.Recent breakthroughs, such as OpenAI’s...
Summary: Researchers have recreated the human ascending sensory pathway in a lab dish, using organoids that model the key brain and spinal cord regions responsible for transmitting pain. This breakthrough allows scientists to observe how pain signals travel from peripheral neurons to the brain for the first time outside the...
Summary: New research in the World Happiness Report reveals that people who regularly share meals with others tend to be happier and more emotionally satisfied, regardless of age, culture, or background. This social behavior was found to be as predictive of happiness as income or employment status.Yet, Americans are increasingly...
Summary: New research highlights how the brain’s own chemistry can suppress pain, explaining why severely injured individuals, like WWII soldiers, sometimes feel little discomfort. The key lies in a brain region called the periaqueductal grey (PAG), which dampens pain signals before they reach conscious awareness.This system releases enkephalins, natural opioids...
Summary: A new study reveals that people with anxiety or depression often underestimate their abilities due to a distorted metacognitive process. Even when they perform tasks well, they tend to focus on moments of low confidence and ignore times when they felt assured.This persistent underconfidence can discourage them from trying...
Summary: A groundbreaking study has revealed that our pupils change size in sync with our breathing—a response now dubbed the “pupillary respiratory phase response.” Researchers confirmed that pupils are smallest around the start of inhalation and largest during exhalation, regardless of lighting, focus, or cognitive effort.This discovery adds a fourth...
Summary: Survivors of the 1995 Oklahoma City bombing continue to carry hidden biological imprints of trauma, even decades after the event and in the absence of visible mental health issues. A new study reveals subtle yet significant changes in stress biomarkers, including cortisol levels, heart rate, blood pressure, and inflammatory...
