"Early Self-Recognition: The Toddler's Journey of Touch and See"

A study from The University of Texas at Austin reveals that toddlers prompted to touch their own faces through vibrating discs developed self-recognition in mirrors about two months earlier than expected, challenging the belief that self-recognition is hardwired and suggesting it's influenced by sensory experiences. The findings emphasize the importance of self-directed exploration for self-knowledge and could reshape interventions for children with motor development delays.

Mice Demonstrate Self-Recognition and Intelligence in Groundbreaking Test

Mice exhibit behavior resembling self-recognition when viewing themselves in mirrors, but only under specific conditions such as familiarity with mirrors, socialization with similar-looking mice, and visible markings on their fur. Researchers have identified a subset of neurons in the hippocampus that are crucial for this self-recognition-like behavior. The study highlights the importance of social experiences and sensory cues in developing self-recognition capabilities, providing valuable insights into the neural mechanisms behind self-recognition.

Mice Show Self-Recognition in Mirror Test

Mice have passed the mirror test, demonstrating the ability to recognize themselves in a mirror reflection. The study, published in the journal Neuron, marks the first time mice have shown mirror-induced self-directed behavior, joining humans, great apes, some monkeys, dolphins, and elephants. Researchers marked the foreheads of dark-furred mice with white ink and observed that the mice groomed themselves in front of the mirror to remove the ink. The mice did not exhibit self-grooming behavior when the ink was a smaller blotch or when it was swapped for black ink. The study also identified specific neurons in the mice's ventral hippocampus that were activated during self-recognition. The researchers hope to further investigate the mice's ability to self-recognize without tactile stimuli and understand how they distinguish themselves from other animals.

"Study Shows Roosters Can Recognize Themselves in a Mirror"

A team of neuroscientists and psychologists from German universities conducted experiments with roosters and mirrors to test their self-recognition abilities. The researchers found that roosters were more likely to crow when they knew there was another rooster on the other side of a mesh, regardless of whether they could see themselves in the mirror or not. This suggests that roosters can determine if something is real or not based on vision, rather than sounds or smells. The study provides possible evidence of roosters passing the self-recognition test, a type of self-awareness observed in only a few animal species.
