A new model incorporates human behavior and fears to predict multiple waves of COVID-19 infections. The 'Triple Contagion' model shows how fear can drive disease resurgence, as people may abandon protective measures prematurely or avoid vaccines due to misinformation.
Scientists have identified a unique subset of inhibitory cells in the amygdala known as apITC, which modulates plasticity in fear learning. The apITC connects to various regions, including thalamic processing centers and sensory areas, to regulate fear-related responses.
Researchers at the University of Zurich found that humans respond more quickly and with higher sensitivity to positive screams, which indicate joy, than to negative screams. The study revealed six distinct types of scream calls, including pain, anger, fear, pleasure, sadness, and joy.
A Norwegian University of Science and Technology study found that regret does not contribute to changes in sexual behavior. Women tend to regret casual sex more than men, while men regret missing opportunities more. The researchers suggest that personality plays a significant role in shaping behavior, rather than emotions like regret.
A new study by psychologists at Emory University found that people can accurately discern most emotions tied to screams, but those of happiness are often misjudged as fear. Screams convey strong emotions, and researchers speculate that this may be an evolutionary carryover bias, where humans err on the side of caution.
A study published in PLOS ONE found that individual psychological variables, such as germ aversion and attachment security, are better predictors of fear and perceived health during lockdowns than environmental factors. The researchers investigated 533 participants across Europe and found that younger age, physical activity, and higher...
