The Science Behind Right-Handedness And Left-Eyed Bias In Humans

The research shows that visual field bias, present from early childhood, helps in recognizing identities and emotions.
Scientists have found that, similar to animals, humans also have behavioural biases that are not unique to our species. A new study published in the journal Scientific Reports suggests that aligning these biases with others may have social benefits.
As per the report titled "Motor-sensory biases are associated with cognitive and social abilities in humans," one such bias is the visual field bias, where a significant portion of the population is faster and more accurate at recognising things thought to develop in early childhood. identities and emotions on one side of their visual field compared to the other. This bias is thought to develop in early childhood.
Research on animals shows that having a bias is not only common but also beneficial. Chicks that peck with an eye bias are better at telling food from pebbles, and those that monitor predators with a specific eye are less likely to be eaten.
