The quiet community of Ngodini, just outside Nelspruit in Mpumalanga, South Africa, woke up to heartbreaking news that left neighbours and relatives in disbelief. Twelve-year-old Ayanda had always been the responsible one. As the eldest of three children, she helped her mother care for her younger siblings, eight-year-old Sipho and four-year-old Amahle. Their mother, Nomsa, worked hard to provide for them, often reminding her children that no matter how difficult life became, they should always love and protect one another. One cold winter morning, the children woke up as usual. Ayanda prepared breakfast while waiting for their mother to get up for work. Minutes turned into an hour, but Nomsa never came out of her bedroom. Ayanda gently knocked on the door. "Mama?" she called softly. There was no answer. She knocked again, louder this time. "Mama, it's morning. You have to wake up." Still, there was only silence. Growing worried, Ayanda tried opening the door. H...

Summary: Study reveals a correlation between instances of eye contact and higher levels of engagement during conversations.

Making eye contact repeatedly when you’re talking to someone is common, but why do we do it? When two people are having a conversation, eye contact occurs during moments of “shared attention” when both people are engaged, with their pupils dilating in synchrony as a result, according to a Dartmouth study published in the Proceedings of the National Academy of Sciences.
“Eye contact is really immersive and powerful,” says lead author Sophie Wohltjen, a graduate student in psychological and brain sciences at Dartmouth.
“When two people are having a conversation, eye contact signals that shared attention is high —that they are in peak synchrony with one another. As eye contact persists, that synchrony then decreases. We think this is also good because too much synchrony can make a conversation stale. An engaging conversation requires at times being on the same page and at times saying something new. Eye contact seems to be one way we create a shared space while also allowing space for new ideas.”
“In the past, it has been assumed that eye contact creates synchrony, but our findings suggest that it’s not that simple,” says senior author Thalia Wheatley, a professor of psychological and brain sciences at Dartmouth, and principal investigator of the Dartmouth Social Systems Laboratory.
“We make eye contact when we are already in sync, and, if anything, eye contact seems to then help break that synchrony. Eye contact may usefully disrupt synchrony momentarily in order to allow for a new thought or idea.”
To examine the relationship between eye contact and pupillary synchrony in a natural conversation, pairs of Dartmouth students were brought into the lab. Wearing eye-tracking glasses and sitting across from each other, each pair was asked to have a conversation for 10 minutes, which was audio and video recorded. Participants could talk about whatever they wanted.
After the conversation was over, the two participants were separated into different rooms and were asked to watch the conversation that they just had and to continuously rate how engaged they were.

The research team looked at how pupillary synchrony increases and decreases around instances of eye contact. The results showed that people make eye contact as pupillary synchrony is at its peak. Pupillary synchrony then immediately decreases, only recovering again once eye contact is broken. The data also demonstrated a correlation between instances of eye contact and higher levels of engagement during the conversation.
“Conversation is a creative act in which people build a shared story from independent voices.” Wheatley adds, “Moments of eye contact seem to signal when we have achieved shared understanding and need to contribute our independent voice.”
The team’s results are consistent with other work, which has illustrated how periodically breaking synchrony can allow for creativity and individual exploration.

Eye contact marks the rise and fall of shared attention in conversation
Conversation is the platform where minds meet: the venue where information is shared, ideas cocreated, cultural norms shaped, and social bonds forged. Its frequency and ease belie its complexity.
Every conversation weaves a unique shared narrative from the contributions of independent minds, requiring partners to flexibly move into and out of alignment as needed for conversation to both cohere and evolve. How two minds achieve this coordination is poorly understood.
Here we test whether eye contact, a common feature of conversation, predicts this coordination by measuring dyadic pupillary synchrony (a corollary of shared attention) during natural conversation.
We find that eye contact is positively correlated with synchrony as well as ratings of engagement by conversation partners. However, rather than elicit synchrony, eye contact commences as synchrony peaks and predicts its immediate and subsequent decline until eye contact breaks. This relationship suggests that eye contact signals when shared attention is high.
Furthermore, we speculate that eye contact may play a corrective role in disrupting shared attention (reducing synchrony) as needed to facilitate independent contributions to conversation.

Picture: Karen Sandison/African News Agency(ANA) MultiChoice’s BEE scheme trying to find 22 000 shareholders who are missing out on millions By Edward West Feb 16, 2021 CAPE TOWN - PHUTUMA Nathi, the MultiChoice black economic empowerment scheme of more than 80 000 shareholders, is looking for about 22 000 shareholders who owned shares and did not receive dividends of R207 million between 2006 and 2020. “This money belongs to our shareholders. We’re calling on them to contact us to get their money. In these tough economic times we want to do everything in our power to give them what is rightfully theirs,” Phuthuma Nathi chairperson Mandla Langa said in a statement yesterday. Phuthuma Nathi has been paying dividends every year since the start of the scheme in 2006. Am...
The speedy LAR-01's automotive interior adds comfort and luxury. Plus: The wings detach, so the jet can be stored in a home garage. By MICHAEL VERDON Courtesy Flaris The Flaris LAR-01 has a number of striking stats, including being a ton lighter (literally) than its competitors, along with an unusually short-field landing capability, and detachable wings. But its most impressive number is the 250-knot true air speed, which its designers say makes it the world’s fastest business jet among single-engine very light jets and turboprop aircraft. Flaris says recent tests “confirmed the assumptions made previously” about the effectiveness of multiple systems, including its Garmin G600 avionics and Flaris Flight Assistance System flight computer, as well as the landing gear and emergency parachute system. But it also claims more impressive stats like the 250-knot TSA at 10,000 feet. Its 6,000-feet-per-minute climb rate, adds the compan...
Here's the story: We sat down with a man who had a harrowing journey with addiction. He began by telling us about his early days in tertiary education, where he would occasionally smoke dagga with friends. However, his focus remained on his studies, and he worked hard to graduate and secure a qualification. After landing a job, he started building a life for himself. He got married, bought a property, and even splurged on a car. Life was good, and he felt like he was on top of the world. But one fateful night, while out with friends, he was introduced to heavier narcotics. At first, the experience was exhilarating. He described it as an elevation from the mild high of dagga to a level 5 high, where he felt invincible and euphoric. The effects would last for days, allowing him to party from Friday to Sunday without sleep. The problem, however, began to manifest on Mondays and Tuesdays every week, when the withdrawal symptoms would kick in, and he'd struggle to function at work....
