For infants, distinguishing between friends and strangers is a laughing matter

Published

on

Infants as young as five months can differentiate laughter between friends and between strangers, finds a new study.

It has been recently established that co-laughter — or simultaneous laughter between two or more individuals — allows adult listeners across different cultures and languages to quickly evaluate the nature of relationships between people: are they friends, acquaintances, or strangers?

The study suggests that the ability to detect this nature of social relationships is instilled early in human infancy, possibly the result of a detection system that uses vocal cues.

“Infants’ sensitivity to different kinds of laughter might be one of the early emerging tools they use to understand and navigate the complex social world,” said Athena Vouloumanos, Associate Professor from the New York University.

“Very brief instances of shared laughter can reveal rich information about people’s relationships, detectable in infants as young as five months of age and universally by adults around the world,” added co-author Gregory Bryant, Professor at University of California-Los Angeles.

For the study, published in the Scientific Reports journal, the team examined how five-month-olds processed exchanges of co-laughter of adults — specifically, those who were strangers and those who were friends — by gauging how long they listened to these sounds.

The team found that infants could not only differentiate between the laughter of friends and strangers, but, when given the choice, they preferred to listen longer to co-laughter between friends.

In another experiment, the team found that infants could tie co-laughter to judgments about human relationships.

“The ability to rapidly evaluate acoustic features in co-laughter that reveal social relationships between individuals appears early in human infancy and might be the product of an adaptive affiliation detection system that uses vocal cues,” the authors said.

Casino Days Reveal Internal Data on Most Popular Smartphones

International online casino Casino Days has published a report sharing their internal data on what types and brands of devices are used to play on the platform by users from the South Asian region.

Such aggregate data analyses allow the operator to optimise their website for the brands and models of devices people are actually using.

The insights gained through the research also help Casino Days tailor their services based on the better understanding of their clients and their needs.

Desktops and Tablets Lose the Battle vs Mobile

The primary data samples analysed by Casino Days reveal that mobile connections dominate the market in South Asia and are responsible for a whopping 96.6% of gaming sessions, while computers and tablets have negligible shares of 2.9% and 0.5% respectively.

The authors of the study point out that historically, playing online casino was exclusively done on computers, and attribute thе major shift to mobile that has unfolded over time to the wide spread of cheaper smartphones and mobile data plans in South Asia.

“Some of the reasons behind this massive difference in device type are affordability, technical advantages, as well as cheaper and more obtainable internet plans for mobiles than those for computers,” the researchers comment.

Xiaomi and Vivo Outperform Samsung, Apple Way Down in Rankings

Chinese brands Xiaomi and Vivo were used by 21.9% and 20.79% of Casino Days players from South Asia respectively, and together with the positioned in third place with a 18.1% share South Korean brand Samsung dominate the market among real money gamers in the region.

Cupertino, California-based Apple is way down in seventh with a user share of just 2.29%, overshadowed by Chinese brands Realme (11.43%), OPPO (11.23%), and OnePlus (4.07%).

Huawei is at the very bottom of the chart with a tiny share just below the single percent mark, trailing behind mobile devices by Motorola, Google, and Infinix.

The data on actual phone usage provided by Casino Days, even though limited to the gaming parts of the population of South Asia, paints a different picture from global statistics on smartphone shipments by vendors.

Apple and Samsung have been sharing the worldwide lead for over a decade, while current regional leader Xiaomi secured their third position globally just a couple of years ago.

Striking Android Dominance among South Asian Real Money Gaming Communities

The shifted market share patterns of the world’s top smartphone brands in South Asia observed by the Casino Days research paper reveal a striking dominance of Android devices at the expense of iOS-powered phones.

On the global level, Android enjoys a comfortable lead with a sizable 68.79% share which grows to nearly 79% when we look at the whole continent of Asia. The data on South Asian real money gaming communities suggests that Android’s dominance grows even higher and is north of the 90% mark.

Among the major factors behind these figures, the authors of the study point to the relative affordability of and greater availability of Android devices in the region, especially when manufactured locally in countries like India and Vietnam.

“And, with influencers and tech reviews putting emphasis on Android devices, the choice of mobile phone brand and OS becomes easy; Android has a much wider range of products and caters to the Asian online casino market in ways that Apple can’t due to technical limitations,” the researchers add.

The far better integration achieved by Google Pay compared to its counterpart Apple Pay has also played a crucial role in shaping the existing smartphone market trends.
