From better batteries to preventing memory loss, nearly four dozen projects at �Թϱ�� and its partner hospitals are being supported by the Ontario Research Fund

Researchers in the University of Toronto’s Thermal Management Systems (TMS) Laboratory are working to improve the way battery systems handle heat and develop structural battery pack components. 

“Whether they are being used for electric vehicles or for stationary energy storage systems that reduce strain on the grid, lithium-ion batteries are transforming the way we use electricity,” said Carlos Da Silva, senior research associate at the TMS Lab in the Faculty of Applied Science & Engineering and executive director of �Թϱ��’s Electrification Hub.

“Unfortunately, today’s batteries are still sensitive to temperature: if they get too cold or too hot, it can degrade their performance and even present safety risks. We are working on new technologies that make batteries more resilient to thermal fluctuations.”

The battery-related research is among nearly four dozen projects at �Թϱ�� and its partner hospitals that are receiving almost $35 million in support through the Ontario Research Fund – Research Excellence (ORF-RE) and the Ontario Research Fund – Small Infrastructure (ORF-SIF). (See the full list of projects and their principal researchers below).

"Research at the University of Toronto and at all universities and colleges across Ontario is the foundation of the province’s competitiveness now and in the future,” said Leah Cowen, �Թϱ��’s vice-president, research and innovation, and strategic initiatives.

“This investment protects and advances cutting-edge, made-in-Ontario research in important economic sectors and helps ensure universities can continue to train, attract and retain the world’s top talent."

At �Թϱ�� Engineering’s TMS Lab, researchers led by Cristina Amon, a University Professor in the department of mechanical and industrial engineering, are working on two funded projects. They are developing advanced computational modelling and digital twin methodologies that predict and optimize how heat flows through battery packs. The methodologies are carefully calibrated and validated through industry-relevant experiments in the lab.

These methodologies will help battery designers anticipate and prevent thermal management challenges before they arise. It can also enable them to optimize the design and deployment of fire mitigation measures, such as ultra-thin heat barriers, within their battery systems.

The team is also collaborating with Ford Canada and several other companies in the energy storage space. For example, they have worked with Jule (powered by eCAMION) on the development of direct current electric vehicle fast chargers with integrated battery energy storage systems, one of which was recently unveiled on the �Թϱ�� campus.

“We are grateful for this ORF-RE funding, which will accelerate our research and help us further expand our partnerships, ensuring that battery thermal innovations have a seamless transition from the lab to the marketplace,” Amon said.

“As a result of this work, the next generation of batteries will be safer and more resilient than ever before, which is especially important in colder climates like ours here in Ontario.”

Researchers find that people who use common messaging shorthands such as "lol" and "ttyl" are perceived as putting less effort into the conversation

Tapping out smartphone messages using shorthand such as “btw” (by the way) or “tbh” (to be honest) may feel breezy and efficient – but a new study warns these and other common abbreviations may make it less likely to get a response.

Whether you’re on a dating app or messaging with fellow gamers, it turns out that using abbreviations makes people believe you’re putting less effort into the conversation. They’ll find your message less sincere and not as worthy of a reply as the exact same text written in full.

“Abbreviations imply informality and casualness – so we thought if somebody uses one, you might read that as a signal of closeness and be more likely to respond,” says study co-author Sam Maglio, a marketing professor in the department of management at the University of Toronto Scarborough and the Rotman School of Management.

“We figured that was perfectly plausible and we found out that was perfectly wrong. An abbreviation makes the other party tune out.”

The study, published in the Journal of Experimental Psychology: General, was based on the results of experiments in the lab and the field, survey data and archival field data.

One experiment examined Tinder conversation histories submitted by 700 users across five continents. Researchers calculated the percentage of abbreviations participants used in their messages on the popular dating app. They found that for every one-per-cent increase in abbreviations, average conversation length decreased by about seven per cent.

When other Tinder users were surveyed, 80 per cent believed their matches wouldn’t care if they used abbreviations. But that wasn't reflected in the data – regardless of profile characteristics, topics discussed, message length or the sophistication of word choices.

Another experiment focused on Discord, a messaging platform popular among young people. They sent almost 2,000 messages to members of a Discord channel dedicated to anime TV shows, asking for a show recommendation.

“We set ourselves up to fail. We tried to find the most challenging arena for this effect to work: young people who live online – and it still worked,” says Maglio.

The Discord messages were probing whether reactions changed based on the type of abbreviations used. That includes: phonological abbreviations that condense words based on how they sound, such as “plz” or “thnx”; acronyms and initialisms like “hru” (how are you?) and “ttyl” (talk to you later); subbing letters or numbers for words, as in “u 2”; and contractions, which shorten words by removing letters, such as “rlly” or “wud.” All forms of abbreviations were less likely to get a reply than their spelled-out counterparts on the platform. The only exception was for the messages that used phonological abbreviations (although this exception was not noted in a subsequent experiment).

In a virtual speed dating experiment, roughly 200 young Americans were paired up for five-minute dates. Half were encouraged to integrate words from one of two lists – an abbreviated version and a spelled-out one – into their conversations. Dates had a much greater desire to continue talking to non-abbreviated texters and viewed them as more sincere. More of their dates also offered to share their contact information to continue chatting after the experiment.

The researchers’ lab-based tests yielded similar results – and the thousands of participants who participated in these studies all rated how much effort they felt were put into the texts, how sincere they felt the sender was being and how likely they were to reply.

The results were the same across the board: abbreviations meant less effort, less sincerity and a lower desire to reply.

“It’s possible that some participants treated the sincerity question as a kind of general ‘good or bad’ evaluation,” says study co-author David Fang, a �Թϱ�� alumnus.

“We mainly chose sincerity because it's important for relational building. Participants are taking a stab at defining what they perceive sincerity to be – for instance expressing genuineness in the interaction.”

Nirmol Midha studied psychology and volunteered with campus groups that offer mental health and wellness supports

As she prepares to graduate from the University of Toronto Mississauga, Nirmol Midha is taking time to reflect on the meaningful lessons, rich experiences and diverse connections that punctuated her journey – including a passion for supporting mental health.

“It’s a really emotional time, because at UTM I developed so much, not only academically but as a person,” says Midha, an international student from India who completed an undergraduate degree in psychology.

“It was a time of self-exploration, growth and discovering my resilience.”

Midha specifically chose to study at the �Թϱ�� Mississauga campus because of its serene natural surroundings and the option to have two minors – in biology and political science.

She says majoring in psychology was a way for her to better understand human motivations and behaviours – and to learn how to support mental health.

“I felt a deep calling to understand people on a deeper level and support their emotional and mental well-being,” she says.

“I think that’s really important in today’s world.”

Midha says she was fascinated to learn about the how the mind develops, the structure and function of the brain, the evolution of cognition in children and how to conduct quantitative research.

She says her professors skillfully brought the topics to life.

“All of the professors at UTM taught really well. They made the concepts so engaging,” she says. “They were helpful, accommodating and always trying to offer a helping hand.”

Midha complemented her classroom learning with mental health-related extracurricular activities.

She served a term as the vice-president of the student club Mending Minds, for which she organized mental health awareness events. She also worked as the education and communication lead at The Wellness Den, a space connected with the Health & Counselling Centre that provides wellness services to support students. There, she created an escape room game to bring awareness to the Den’s offerings.

“The goal at the Den was to let students know that we all deal with academic and life pressures – and sometimes it’s a lot, but everything’s going to be fine,” she says.

Like other Class of 2024 grads, Midha’s education was interrupted by the COVID-19 pandemic that forced �Թϱ�� to hold many classes virtually for an extended period. Missing out on so much campus life was difficult, she says, but notes she was able to find her stride with online learning and maintain her circle of friends.

She says remote learning also allowed her to attend her nephew, who was unwell.

“Everything’s going to have its positives and negatives,” she says. “You just have to look at the positive side and move on with it.”

While Midha is considering future studies in social work and speech-language pathology, she is currently focused on research, administration and mental health roles.

What she knows for sure is that she wants to apply what she has learned about human psychology and wellness so she can help others. That includes through her volunteer role as vice-president of marketing for UTM Campus Connections, a club that supports community members with intellectual disabilities.

“I want to use what I’ve learned at UTM to make a meaningful impact in people’s lives,” she says. “I hope to contribute to something bigger than myself in the future.”

"Our data suggests that you can be hard-working, motivated and a chronic cannabis user at the same time."

Cannabis users might not be as lazy and unmotivated as popular stereotypes suggest, according to new research from the University of Toronto.

In a study published in the journal Social Psychological and Personality Science, researchers found that regular cannabis use had minimal effects on motivation and willpower, and that getting high was associated with more positive emotions and fewer negative ones.

The research aimed to take an objective look at the effects of recreational cannabis on the daily lives of chronic users, says Michael Inzlicht, a professor in the department of psychology at �Թϱ�� Scarborough who led the study.

“There is a stereotype that chronic cannabis users are somehow lazy or unproductive,” says Inzlicht, who is cross-appointed to the Rotman School of Management. “We found that’s not the case – their behaviours might change a bit in the moment while they’re high, but our evidence shows they are not lazy or lacking motivation at all.”

For the study, scientists surveyed 260 chronic cannabis users – defined as those who used cannabis at least three times a week – five times per day over the course of a week. Participants received notifications through an app asking if they were high, and were then prompted to answer questionnaires that assessed their emotional state, motivation levels, willpower and self-regulation.

Inzlicht says the most interesting finding relates to motivation, with participants found to be just as willing and motivated to exert effort in completing a task when high compared to when sober.

Past research has shown mixed results when it comes to chronic cannabis use and motivation, with Inzlicht noting much of it relied on limited experimental designs that didn't account for differences between cannabis users and non-users, including variations in personality, mental health or use of other psychoactive substances.

He says this study accounted for those pre-existing differences and also looked at chronic cannabis use while participants were actively high.

The researchers did find that being high was associated with lower levels of self-regulation, an important trait for being able to accomplish tasks. Specifically, chronic users reported being more impulsive, less thoughtful and less orderly.

“These things can detract someone from getting stuff done, but we didn’t find it made them less hard-working, responsible or able to focus,” says Inzlicht, who runs the Work and Play Lab, which does research on self-control, motivation and empathy as well as social media, digital devices and recreational cannabis use.

Chronic cannabis users were also found to experience a boost in positive emotions such as awe and gratitude when they were high, and a reduction in some negative emotions such as fear and anxiety. However, more chronic users were found to experience more negative emotions while high as well as while sober.

The study also found no evidence of a “weed hangover” the day after cannabis use.

Inzlicht notes that studying the effects of daily cannabis use was difficult in the past due to its legal status, and that most scholarship on the topic focused on negative impacts in an effort to curb use.

Now that cannabis is legal in Canada, however, Inzlicht says he expects there will be more research focusing on both positive effects and risks.

“The cannabis literature, historically, tended to focus a lot on the negative medical consequences of chronic use,” says Inzlicht. “Part of the motivation for this study is to take a neutral, clear-eyed approach to see how cannabis affects chronic users in their everyday lives.”

He adds the study isn’t an endorsement of heavy cannabis use, pointing out there is plenty of research highlighting its risks – especially among adolescents.

Rather, he points to Statistics Canada data showing that nearly one in 10 adult Canadians are regular cannabis users, and they come from all walks of life. Cannabis is also the fourth most used recreational drug after caffeine, alcohol and tobacco. But despite its increased legal and social acceptance, relatively little is known about the everyday experiences of regular users.

“Our data suggests that you can be hard-working, motivated and a chronic cannabis user at the same time.”

The study received funding from the Social Sciences and Humanities Research Council of Canada.

Nominated for a Webby award, Defy Dementia was created by Allison Sekuler, a researcher at the Baycrest Centre and �Թϱ�� psychology professor, and science communicator Jay Ingram

Cognitive neuroscientist Allison Sekuler says she and science communicator Jay Ingram launched the Defy Dementia podcast to empower people to make simple changes to improve their brain health.

What she didn’t expect was that the project would inspire her to make changes of her own.

As the Baycrest Centre’s Sandra A. Rotman Chair in cognitive neuroscience at the Rotman Research Institute and president and chief scientist of Baycrest Academy for Research and Education and Centre for Aging + Brain Health Innovation, Sekuler is well-versed in the growing body of science linking dementia risk to lifestyle factors such as social isolation, sleep and exercise.

But when Defy Dementia launched a year ago, Sekuler admits that she had fallen into a rut on the fitness front. Despite continuing to pay monthly membership fees, she hadn’t set foot in a gym since the COVID-19 lockdowns in early 2020.

That soon changed as she and Ingram heard from listeners who were putting the podcast’s advice into practice.

“It’s been gratifying, intellectually, that we're able to make a difference in people's lives,” says Sekuler, who is a professor of psychology in the University of Toronto’s Faculty of Arts & Science. “But it's also had a deep personal impact on me, inspiring me to get myself up off the couch and start becoming more active.”

In particular, she credits two podcast conversations with getting her back into the gym: a pep talk from octogenarian bodybuilder Ernestine Shepherd, and the story of listener-turned-guest Ravi Venkatesh, an IT specialist in Mississauga, Ont., who told the hosts how the podcast had motivated him to recommit to his yoga regimen.

As Sekuler sees it, she’s just one beneficiary of the community of learning that has sprung up around Defy Dementia, which is currently vying for a voter-chosen Webby Award for podcasts in the health, wellness and lifestyle category (voting is open until April 18).

A general term encompassing several diseases that impair memory, thinking and reasoning, dementia is projected to afflict 150 million people by 2050, including more than one million in Canada, according to research published in The Lancet.

“Obviously, nobody wants to get dementia, and there are things you can do to decrease your risk. But even people who are living with the disease, it's not necessarily, you know, a death sentence,” says Sekuler, whose research specializes in the links between perception, memory and aging.

“Our goal was … to portray a realistic view of the disease and of aging, but [also] to show the possibilities that are there.”

Sekuler is among the scientists at the Baycrest Centre working to advance the field of “precision aging,” applying the principles of precision medicine to aging and brain health to detect, treat and care for people with dementia in a personalized way.

Research suggests we have more control over dementia than one might think – a 2020 report by the Lancet Commission found a dozen modifiable risk factors account for 40 per cent of dementias, including hearing impairment, smoking and obesity – but Sekuler stresses that many of the interventions under development are only effective if the disease is caught early.

Hence, a key challenge facing the field is the popular belief that dementia is a disease determined solely by your genes.

On Defy Dementia, Sekuler and Ingram, who have been collaborating since the 1990s, push back against this misconception by offering tips on reducing risk through lifestyle changes. That includes episodes focused on subjects such as cognitive engagement, nutrition, sleep and stress.

Sekuler attributes much of the podcast’s resonance to its format. Each episode features one guest sharing their personal experience with dementia, followed by a scientist who responds to the story with expert context and insights.

“It made the science that much more accessible and relatable,” she says.

Sekuler says she was surprised to find that people of all ages are tuning in – not just the older crowd that she and Ingram initially expected to attract.

“You’re never too young or too old to take care of your brain,” Sekuler says. “The sooner you start taking actions to improve your lifestyle, the more it becomes a habit for you throughout your life.”

"Our study contributes to a more complex picture of single lives that goes beyond the misleading stereotype of the miserable single person”

The phrase “single life” may conjure images of a busy Sex and the City-like social calendar, packed with dates and drama. But researchers at the University of Toronto say most singles are actually introverts – a far cry from the extroverted stereotypes we often see depicted in movies and on TV.

In a study published recently in the Personality and Social Psychology Bulletin, the researchers reveal how certain personality traits – particularly how extroverted, conscientious and neurotic someone is – predict who is likelier to be single or in a relationship.

It’s one of several links between personality, well-being and relationship status described in the research.

“As marriage rates decline and more people live alone, our study contributes to a more complex picture of single lives that goes beyond the misleading stereotype of the miserable single person,” says lead author Elaine Hoan, a PhD candidate in in the lab of Geoff MacDonald, a professor in the department of psychology in the Faculty of Arts & Science.

“While on average people in relationships are more satisfied with their lives than single people, there are many happy singles – relationships don't play as big of a role in one’s overall life satisfaction as you may think.

“We found that personality, more than relationship status, determines who is happy with their life and who isn’t.”

For the study, researchers recruited over 1,800 participants between the ages of 20 and 59 who had either been single for at least six months or in a relationship for at least six months. Participants completed a set of questionnaires that measured personality, satisfaction with relationship status, sexual satisfaction and life satisfaction to shed light on how personality traits affect well-being in the context of relationship status.

For the personality measurement, Hoan used the “Big Five” model of personality, which focuses on the following traits: extroversion (outgoing and high-energy), agreeableness (compassionate and respectful), conscientiousness (productive and dependable), neuroticism (anxious and depressed) and openness (curious and creative).

Where someone fell on the introversion and extraversion scale was more strongly related to whether they would be single or in a relationship.

“In a world that caters to extroverts, introverts are misrepresented as antisocial,” says Hoan. “The reality is, introverts enjoy their alone time and independence, and can emotionally regulate – meaning, they can manage their reactions to their feelings on their own. So, an introvert may prefer being single more than being in a relationship.

“On the other hand, extroverts are happier than introverts in general – regardless of whether they were single or not – and introversion makes it a bit tougher to get into a relationship in the first place because introverts may not find themselves in social situations as often.

“Other existing research also suggests that being in a relationship may make someone more extroverted, by increasing confidence and widening their social circle.”

The researchers also found notable, though weaker, connections to the traits of conscientiousness and neuroticism. Single people were less likely to identify with descriptors like “keeps things neat and tidy” and “gets things done” and agreed more strongly with phrases like “can be tense”, “often feels sad” and “is temperamental.”

“Conscientious people are more likely to be goal-oriented, especially towards traditional goals like getting a job and getting married, as well as exhibit a strong work ethic, so that may feed into their desire and ability to start and commit to a romantic relationship,” says Hoan. “Depressive symptoms like sadness and low energy may make it more difficult to pursue and maintain a relationship – while the emotional support you get in a romantic relationship could reduce these symptoms.”

Next, Hoan is researching happiness in married versus unmarried people. She hopes her work continues to challenge societal misconceptions about who people are and how they choose to live their lives, whether in a relationship or not.

“There is stigma associated with being single – you know, people saying, ‘You’d be happier if you were in a relationship, so why aren’t you?’ – when that’s not necessarily true for everyone,” she says.

“I hope what people take from our research is the idea that you don’t have to be someone you’re not – just be yourself.”

�Թϱ�� Mississauga's Emily Impett and her collaborators say good relationships are more like a balanced diet, where people receive a wide range of essential nutrients

Even if you don’t know your love language, you’ve probably heard of the concept.

The theory’s pervasiveness in pop culture has only increased in the 30-odd years since Baptist minister Gary Chapman published his book The Five Love Languages: The Secret to Love That Lasts.

But when psychology researchers at the University of Toronto decided to test Chapman’s main assumptions, they found they don’t stand up to scientific scrutiny.

“We were very skeptical about the love languages idea, so we decided to review the existing studies on it,” says Emily Impett, a professor in �Թϱ�� Mississauga’s department of psychology who collaborated with graduate student Gideon Park and York University Assistant Professor Amy Muise.

“None of the 10 studies supported Chapman’s claims.”

For example, Chapman uses the language metaphor to represent how individuals tend to prefer giving and receiving love. The notion rests on three premises: that every person has a primary love language, that there are five love languages (physical touch, words of affirmation, acts of service, quality time and gifts), and that when couples “speak” the same love language it improves the quality of their relationships.

But each of these assertions broke down when Impett and her team evaluated them against the 10 studies they reviewed (the team’s results are scheduled to be published in the journal Current Directions in Psychological Science).

“People determine their primary love language by taking Chapman’s quiz, which forces them to select the expressions of love they find most meaningful,” says Impett, who is also the director of the Relationships and Well-Being Laboratory. “It could be choosing between receiving gifts or holding hands, for example. These are trade-offs we don’t have to make in real life.

“In fact, people report that they find all of the things described by the love languages to be incredibly important in a relationship.”

When it comes to the number of love languages, the studies found inconsistent evidence for the five languages Chapman identifies, while other relationship research shows there are additional ways of expressing and receiving love.

“One key thing to remember is that Chapman developed the five love languages by working with a sample of white, religious, mixed-gender, traditional couples,” says Impett. “There are certain things that are left out, such as affirming a partner’s personal goals outside of the relationship, which might be significant to couples with more egalitarian values.”

Most importantly, Impett and her team found no scientific evidence for Chapman’s central contention that people who choose partners that speak their love language, or learn to speak it, will have more successful relationships.

“There’s no support for this matching effect,” says Impett. “People are basically happier in relationships when they receive any of these expressions of love.”

Impett and her collaborators recognize that people crave easy tools to enhance their love lives – which helps explain why Chapman’s book has sold millions of copies and turned the “love languages” into romantic shorthand.

“Everyone wants to be in a good relationship, so we didn’t just say the love languages are scientifically debunked and stop there,” she says.

The team offered an alternative metaphor – one that’s rooted in research. It proposes that relationships are a balanced diet, where people need a full range of essential nutrients (including the factors described by the five love languages and others such as companionship and emotional support) to nourish lasting love.

“It keeps all expressions of love on the menu and invites partners to share what they need at different times,” says Impett. “It allows for the fact that people and relationships aren’t static and can’t be categorized into neat boxes.”

This is not the first time Impett has put common beliefs about relationships to the test. “I really like challenging these lay ideas because my goal is always to translate the best scientific evidence to therapists and the general public,” she says.

Paul Bloom says psychology is "about the most interesting topic there is – us"

Paul Bloom’s latest book kicks off by recounting a daydream in which he quits his job as a psychology professor to venture into the world of cosmology.

But his fantasy of studying the vast reaches of the universe was brief because, he writes, “...all of psychology gives me this buzz. It’s about the most interesting topic there is – us. It’s about our feelings, experiences, plans, goals, fantasies, the most intimate aspects of our being.”

A professor in the University of Toronto’s department of psychology in the Faculty of Arts & Science, Bloom’s research focuses on developmental psychology, personality and how we make sense of the world – with a particular interest in pleasure, morality, religion, fiction and art.

His seventh book, Psych: The Story of the Human Mind, had its origins in the introductory psychology course Bloom taught at Yale University and, as such, provides an excellent overview of major aspects of psychology.

In its pages, he attempts to “put forth the best answers we have” to the fundamental questions most have pondered: How does the brain give rise to intelligence and conscious experience? Where does knowledge come from? How and why do we differ in personality, intelligence and other traits? How does the mind of a child differ from that of an adult? What makes people happy?

He also provides an overview of the different schools of psychological thought that offered their own best answers to the queries.

He describes the mechanistic or materialist point of view that our thoughts and emotions are the output of a vast assembly of nerve cells and the result of interactions between various molecules – or as Nobel Prize-winner and co-discoverer of the helical structure of DNA Francis Crick wrote: “Brain makes thought.”

He also describes “Cartesian dualism,” named for French philosopher and scientist René Descartes – the idea that our minds and our physical selves are distinct entities. In other words, we are bodies and souls. We feel certain, Bloom writes, “we are not our bodies; we inhabit these bodies. We are Ghosts in the Shell.”

Psych is filled with anecdotes and intriguing facts that help explain psychological principles and bring them to life – insights that would’ve sparked curiosity and interest among the students who either enrolled in the Yale course or took the online version of it that Bloom later developed.

He tells the story of Phineas Gage, who in 1848, while working on the construction of a railway, had a metal rod blasted through his brain. Gage survived and retained the ability to speak and understand language, as well as other intellectual capacities. However, Gage eventually suffered severe changes to his personality and emotional states, began having seizures and died – a clear demonstration of how physical damage to the brain affects who we are.

Bloom wrote the book during COVID-19, and he uses the pandemic to discuss the question: “If we’re so smart, why do we often seem so dumb?” Why is Holocaust denial still rampant, why do some believe 9/11 was an “inside job,” why are there so many followers of QAnon who believe, among other absurdities, that the actor Tom Hanks is a Satanist?

And why has COVID-19 become so politicized with so little regard to science? In writing about conspiracy theories like these, Bloom describes how beliefs about the disease contrast starkly between Democrats and Republicans (with neither side having a monopoly on accuracy). He cites a study showing that subjects supported a hypothetical government program, not on its merits, but on whether they were told it was a Democratic or Republican initiative.

Nonetheless, Bloom is optimistic and writes that, despite our irrationality, “... we are also the animal that is capable of acting intelligently for the long-term good...and tries to see things as they really are.”

The questions of consciousness and mind that Bloom raises in his book point to just how vast the story of the human mind is – despite its miniscule size compared to, say, a galaxy.

“The more you look at the mind and how it works from a serious scientific point of view, the more you appreciate its complexity, its uniqueness, and its beauty.”

Survey suggests likelihood of problematic smartphone use greater among women, young people

Are you addicted to your smartphone? If so, you're not alone.

A team of researchers at the University of Toronto have collected the largest set of data in any study regarding problematic smartphone use.

The study – published in the International Journal of Mental Health and Addiction – found that among 41 countries with at least 100 participants, women scored higher than men in problematic smartphone use, with the results being inversely proportional to age. That is, the older a user is, the less likely they are to have problematic smartphone use.

“We weren’t expecting this kind of robust consistency,” says study co-author Jay Olson, a post-doctoral researcher in the department of psychology at �Թϱ�� Mississauga.

The data also allowed researchers – including Dasha Sandra, a PhD student in the department of psychological clinical science at �Թϱ�� Scarborough – to identify geographic patterns since it covered multiple countries across several continents.

The highest scores of problematic use were found in Southeast Asia, while the lowest were in Europe.

Olson says the results prompt “fundamental questions in the field” such as: Why are women shown to have higher rates of problematic smartphone use? What is it about young people that increases their likelihood of problematic use? And what are the social and cultural differences from country to country that influence these results?

The researchers collected survey responses from 50,423 participants aged 18 to 90 across 195 countries. Survey participants answered questions according to the Smartphone Addiction Scale, a widely used measure to study problematic smartphone use.

Olson says problematic use among women may have something to do with how each gender generally uses their smartphones.

“Researchers think women tend to use their phones more for social reasons: communication with friends and family via social media,” he says, adding that uses related to social validation (for example, “likes” on Instagram) are “the kinds of uses that can build habits very quickly.”

It’s not that men don’t use their phones for social reasons, he says, but it’s believed they tend to use fewer social functions such as keeping up with group chats, connecting with family or following influencers.

The research team aims to test this hypothesis as they continue to analyze the data.

Problematic usage can also reflect distress or anguish experienced by individuals.

“People try to avoid negative emotions by using their phone – kind of like an adult pacifier,” he says, noting differences in both gender and age can be related to differences in distress levels.

The research also accounts for cultural differences around smartphone use. Using an index of “cultural tightness” and “cultural looseness,” researchers examined the data through varying social norms across the globe. The distinction can also be made by examining collectivist cultures – which prioritize group connections – versus individualist cultures.

Their hypothesis is that strictness of social norms plays a role in smartphone use. In an individualistic culture, for example, “it’s not expected that you would be calling your family every day,” Olson says.

Another factor is the number of available screens competing for users’ attention. Olson notes that some countries bypassed widespread laptop and desktop computers in favour of developing mobile data networks, meaning that smartphones became people’s primary computing device. For example, Europe, which recorded the lowest rates of problematic use, has been using the internet since it first arrived on personal computers in the 1980s and 1990s. Southeast Asia, by contrast, recorded the highest rates of problematic use and had widespread adoption of the internet via smartphones in just the last 15 years.

“It explains some differences in screen time,” Olson says.

Not all smartphone use is problematic since it largely depends on how an individual is using a phone.

“A social media manager could be logging eight hours of screen time a day, but this doesn’t necessarily have a problematic effect on your life versus somebody who uses their phone for half an hour from midnight to 12:30 a.m. while trying to fall asleep,” Olson explains.

The research team plans to run a longer-term version of the survey to track smartphone use over time. It’s also looking into developing a habit-based intervention for problematic smartphone usage, for which data like this is critical.

“This is in some sense a global experiment,” Olson says. “Smartphones became popular around 2008 and we’re just tracking the effects of this globally, post-hoc.”
