Impulsive Facebook use linked to brain imbalance

March 18, 2017

Washington, Mar 18: The impulsive act of checking Facebook while driving, in a work meeting, or at other times that could have negative consequences is linked with a deficiency in the balance between two systems in the brain, scientists say.

The greater the imbalance between the two systems, the more likely individuals were to engage in problematic social media use behaviours, researchers said.

Researchers, including those from DePaul University in the US, obtained responses from about 341 undergraduate college students who use Facebook.

They collected and analysed problematic Facebook use data during one semester and then followed up with each student the next year to track their academic performance - in this case using grade point average - for both semesters and cumulatively.

They found that individuals who displayed higher levels of problematic use of Facebook had a strong cognitive-emotional preoccupation (system 1)and a weak cognitive-behavioural control (system 2), creating an imbalance.

System 1 is automatic and reactive, quickly triggered, often subconsciously, in reaction to stimulus such as a sight of or notifications from social media, said Hamed Qahri-Saremi, of DePaul University.

System 2 is a reflective, reasoning system that moves more slowly, regulates cognitions, including the ones generated by system 1, and controls behaviours, said Qahari-Saremi. The second system can help individuals control impulses and behaviours that are not in their best interest, he added.

Researchers found that 76 per cent of respondents reported using Facebook in class, 40 per cent reported using Facebook while driving. As many as 63 per cent reported using Facebook while talking face-to-face with others and 65 per cent reported using Facebook at work instead of working.

"The clear and strong effect of problematic social media use on an academic performance was astounding," said Ofir Turel, a professor at California State University in the US.

"A slight increase in problematic social media use translates into significant grade loss, and this declined performance is persistent - it remained one year after our initial study," he added.

The study was published in the Journal of Management Information Systems

Bengaluru: In a shocking revelation, a former member of Hassan Zilla Panchayat (ZP) has accused incumbent JD(S) MP Prajwal Revanna of raping her multiple times over three years and videographing the alleged crime.

A case was registered by the Criminal Investigation Department (CID) based on the statement by the 44-year-old survivor on Wednesday, May 1.

According to the First Information Report (FIR), the woman claimed that when she was a ZP member she used to visit the MLAs and MPs for various development works.

In one such instance in 2021, she met Prajwal seeking his help to get hostel seats for some female students at a local college. The woman, in her statement, said that since the MP was busy, she was asked to meet him the next day.

“The following day I visited the MP at his office and the MP's quarters in Hassan. The staff present there told me to wait on the first floor as there were many others in the hall. Prajwal spoke to some of the women waiting there, spoke with them and sent them off until I was the only one left,” the woman alleged.

As per the survivor, the MP then called her inside a room and she obliged.

“He held my hand, pulled me inside and locked the door. When I asked him why was he closing the door, he told me nothing would happen and made me sit on the bed. He said my husband should talk less and warned me of the consequences. He also said that because of my husband, his mother, Bhavani Revanna, missed the MLA ticket. He told me that if my husband wants to grow politically, I should listen to him [Prajwal],” the woman alleged.

Next, Prajwal allegedly told the woman to lie down on the bed and undress. When the woman refused and said that she would shout, Prajwal allegedly threatened her that he had a gun and warned of dire consequences for her and her husband.

The woman alleged that Prajwal took out his mobile phone and then raped her.

“He raped me and sexually assaulted me and recorded the act on his mobile phone,” the woman alleged. “He threatened to leak the video if I ever spoke about it and told me to be there whenever he wanted. After that, he used to video call me frequently, ask me to be naked during the call and raped me in multiple instances.”

The woman claimed that she was scared and did not make the incident public and chose to come forward after she learnt of the Special Investigation Team (SIT) set up by the Karnataka government to probe the alleged Hassan sex scandal.

A case was registered under Sections 376(2)(n) (commits rape repeatedly on the same woman), 506 (criminal intimidation), 354A(1)(physical contact and advances involving unwelcome and explicit sexual overtures), 354B (assault or use of criminal force to woman with intent to disrobe) and 354C (voyeurism) of the Indian Penal Code (IPC) and 66E (violation of privacy) of the Information Technology (IT) Act.

Prajwal is also accused in a sexual harassment case along with his father, Holenarasipur MLA HD Revanna, registered at the Holenarasipur police station in Hassan on April 28.

The maximum temperatures are likely to continue and also be around 40 to 46 degrees Celsius over parts of NIK districts, such as Raichur, Kalaburgi, Yadgir, Bellary and Vijayapura districts till May 6, the natural disaster management centre said on social media platform X.

Mangaluru: The Bengaluru-Mangaluru air route has recently surpassed the Mumbai route to become the busiest for Mangaluru International Airport.

According to the Directorate General of Civil Aviation’s city pairing data for March this year, 51,734 passengers travelled between Mangaluru and Bengaluru, while 50,340 passengers flew on the Mangaluru-Mumbai route.

In January and February, the Mumbai air route had the highest passenger flow with 60,306 and 52,732 passengers, respectively, compared to 53,509 and 47,530 for Bengaluru during the same months. However, the trend shifted in March, with the Bengaluru-Mangaluru route surpassing Mumbai.

An official from MIA explained, “The first reason for Bengaluru taking over Mumbai is that flights that almost fly full to Mumbai were reduced from March, after the ministry of civil aviation suggested easing air traffic congestion at Mumbai airport. The air carrier IndiGo, which used to operate four flights a day from MIA, reduced it to three. Air India Express, which operates two flights a day, has made no changes. As a result of this, Bengaluru has taken over Mumbai. A total seven flights operates per day to Bengaluru.” 

The official added that despite the reduction in flights, the Mumbai route still experiences high demand. DGCA data for 2023 shows that the Mumbai and Bengaluru sectors have experienced growth of 11.9% and 19.3%, respectively.

The Mangaluru-Mumbai sector has seen a total of 5,52,767 passengers, followed by Bengaluru with 5,52,500 passengers in the same calendar year.
