Molecules that promote plant-to-plant communications below ground

Plants have evolved elaborate mechanisms for detecting neighboring plants, which typically involve the perception of "cues'" inadvertently produced by their neighbors. Strigolactones are hormonal signaling molecules that ...

Individual cells are smarter than thought

Humans make decisions based on various sensory information, which is integrated into a holistic percept by the brain. But how do single cells make decisions? Much more autonomously than previously thought, as researchers ...

Photonic synapses with low power consumption and high sensitivity

Neuromorphic photonics/electronics is the future of ultralow energy intelligent computing and artificial intelligence (AI). In recent years, inspired by the human brain, artificial neuromorphic devices have attracted extensive ...

Exploring how diverse social networks reduce accent judgments

Everyone has an accent. But the intelligibility of speech doesn't just depend on that accent; it also depends on the listener. Visual cues and the diversity of the listener's social network can impact their ability to understand ...

How variability shapes learning and generalization

Variability is crucially important for learning new skills. Consider learning how to serve in tennis. Should you always practice serving from the exact same location on the court, aiming at exactly the same spot? Although ...

Examining paleolithic tools and visual perception

Scientists at the Centro Nacional de Investigación sobre la Evolución Humana (CENIEH) have analyzed the influence of the shape of Paleolithic tools on visual attention during handling in a study led by María Silva Gago ...

Correcting COVID-19 misinformation

There has been serious discussion about COVID-19 misinfomation. That misinformation has most likely cost many people their lives, driven by messages from those with a hidden agenda to drive everyday people away from science-based ...

Exploring the origins of molecular paleontology

If "Jurassic Park" fueled your interest in dinosaurs, genetics, and all things ancient, you aren't alone. There's an entire field dedicated to looking for ancient DNA—molecular paleontology—that predates Michael Crichton's ...

Perception

In philosophy, psychology, and the cognitive sciences, perception is the process of attaining awareness or understanding of sensory information. It is a task far more complex than was imagined in the 1950s and 1960s, when it was predicted that building perceiving machines would take about a decade, a goal which is still very far from fruition. The word comes from the Latin words perceptio, percipio, and means "receiving, collecting, action of taking possession, apprehension with the mind or senses."

Perception is one of the oldest fields in psychology. The oldest quantitative law in psychology is the Weber-Fechner law, which quantifies the relationship between the intensity of physical stimuli and their perceptual effects. The study of perception gave rise to the Gestalt school of psychology, with its emphasis on holistic approach.

What one perceives is a result of interplays between past experiences, including one’s culture, and the interpretation of the perceived. If the percept does not have support in any of these perceptual bases it is unlikely to rise above perceptual threshold.
