Dogs’ brains are sensitive to the familiar high-pitched “cute” voice tone that adult humans, especially women, use to talk to babies, according to a new study.
The research, published recently in the journal Communications Biology, found “exciting similarities” between infant and dog brains during the processing of speech with such a high-pitched tone feature.
Humans tend to speak with a specific speech style characterised by exaggerated prosody, or patterns of stress and intonation in a language, when communicating with individuals having limited language competence.
Such speech has previously been found to be very important for the healthy cognitive, social and language development of children, who are also tuned to such a high-pitched voice.
But researchers, including those from the Eötvös Loránd University in Hungary, hoped to assess whether dog brains are also sensitive to this way of communication.
In the study, conscious family dogs were made to listen to dog, infant and adult-directed speech recorded from 12 women and men in real-life interactions.
As the dogs listened, their brain activities were measured using a functional magnetic resonance imaging (fMRI) scan.
The study found the sound-processing regions of the dogs’ brains responded more to dog- and infant-directed than adult-directed speech.
This marked the first neurological evidence that dog brains are tuned to speech directed specifically at them.
“Studying how dog brains process dog-directed speech is exciting, because it can help us understand how exaggerated prosody contributes to efficient speech processing in a nonhuman species skilled at relying on different speech cues,” explained Anna Gergely, co-first author of the study.
Scientists also found dog- and infant-directed speech sensitivity of dog brains was more pronounced when the speakers were women, and was affected by voice pitch and its variation.
These findings suggest the way we speak to dogs matters, and that their brain is specifically sensitive to the higher-pitched voice tone typical to the female voice.
“Remarkably, the voice tone patterns characterizing women’s dog-directed speech are not typically used in dog-dog communication – our results may thus serve evidence for a neural preference that dogs developed during their domestication,” said Anna Gábor, co-first author of the study.
“Dog brains’ increased sensitivity to dog-directed speech spoken by women specifically may be due to the fact that women more often speak to dogs with exaggerated prosody than men,” Dr Gabor said.
Demystifying Mango Worm Infestations: How Do They Occur and Steps to Stay Protected”
Title: “Demystifying Mango Worm Infestations: How Do They Occur and Steps to Stay Protected”
Introduction:
Mango worms, scientifically known as Cordylobia anthropophaga, are parasitic insects commonly found in parts of Africa and South America. These tiny yet notorious creatures are known for causing a peculiar and sometimes painful infestation in humans. In this article, we will unravel the causes, symptoms, and most importantly, the step-by-step measures to prevent mango worm infestations.
Step 1: Understanding the Mango Worm Lifecycle
Before we delve into preventive steps, it’s essential to comprehend the life cycle of mango worms. Mango worm larvae reside in the soil and often attach themselves to human hosts during specific activities.
Step 2: High-Risk Activities
People become more vulnerable to mango worm infestations during outdoor activities. Here’s what you need to be aware of:
– Walking Barefoot: In regions where mango worms are prevalent, walking barefoot is common. However, this practice can increase your risk of contact with larvae in the soil, which can burrow into your skin, especially on your feet.
– Ground Contact: Spending time on the ground for leisure, picnicking, or agricultural work can raise your chances of infestation. The larvae can transfer onto your skin during contact with the ground.
– Clothing Choices: Wearing clothing that exposes your skin, such as shorts and sleeveless tops, can make you susceptible to infestations. Larvae can attach to exposed areas and burrow into the skin.
Step 3: Recognizing the Symptoms
Once the larvae infiltrate the skin, they develop into mature worms, leading to symptoms like itching, pain, and visible lumps or bumps. If you experience these symptoms, it’s crucial to address them promptly.
Step 4: Preventive Measures
To safeguard yourself from mango worm infestations, follow these easy-to-implement steps:
– Wear Closed-Toe Shoes: When venturing into areas where mango worms are present, choose closed-toe shoes to protect your feet from contact with larvae in the soil.
– Avoid Ground Contact: If possible, refrain from direct contact with the ground. Use blankets, mats, or seating to create a barrier between yourself and the soil.
– Apply Insect Repellent: Using insect repellent on exposed skin can be a powerful defense against mango worm larvae.
Conclusion:
In conclusion, mango worm infestations can be avoided by understanding their causes and taking simple yet effective preventive measures. By wearing appropriate footwear, avoiding direct ground contact, and using insect repellent, you can significantly reduce the risk of infestations. Stay informed and protect yourself from this unique and uncomfortable parasitic experience,
