New study challenges 'pop psychology' myths about habits



UNIVERSITY OF SURREY




By ditching 'pop psychology myths' about habits, we can better understand our habits and take more effective action, according to researchers at the University of Surrey.  

Pop psychology tends to portray all stable behaviours as habitual, as well as implying that forming new habits will always lead to positive long-term change. 

New analysis by Surrey researchers argues that a habit is simply a mental link between a situation (cue) and an action (response). When someone with a habit is in the situation, an unconscious urge prompts the action. However, whether this urge leads to habitual behaviour depends on other competing impulses that influence our actions. 

Dr Benjamin Gardner, co-author and Reader in Psychology from the University of Surrey, said:  

"Forming a habit means connecting a situation you often encounter with the action you usually take. These connections help by creating impulses that push us to do the usual action without thinking. But the pushes from habits are just one of many feelings we might have at any time. 

"Impulses are like babies, each crying for our attention. We can only tend to one at a time. These impulses come from various sources – intentions, plans, emotions, and habits. We act according to whichever impulse demands our attention by crying the loudest at any given moment. 

"Habit impulses usually cry the loudest, guiding us to do what we normally do, even when other impulses are vying for our attention. However, there are times when other impulses cry louder." 

Other impulses can overrule your habits – like cold weather derailing your habitual morning run.  

The paper points out that forming a new habit creates an association that can help keep you on the right track, but it does not ensure that a new behaviour will always stick. 

Dr Phillippa Lally, co-author of the study and Senior Lecturer in Psychology from the University of Surrey, said:  

"Think of someone who has developed a habit of eating a healthy breakfast every morning. One day, they wake up late, leave the house without having time for breakfast, and then grab a sugary snack on their commute. 

"This single disruption can make them feel like they've failed, potentially leading them to abandon the healthy eating habit altogether.  When trying to make a new behaviour stick, it's a good idea to form a habit and have a backup plan for dealing with setbacks, such as keeping healthy snacks on hand that you can quickly grab on busy mornings." 

As for breaking bad habits, the Surrey researchers suggest several methods. 

Dr Gardner explains:  

"There are multiple ways to stop yourself from acting on your habits. Imagine you want to stop snacking in front of the TV. One way is to avoid the trigger - don't switch on the set. Another is to make it harder to act impulsively – not keeping snacks at home. Or, you could stop yourself when you feel the urge. 

"While the underlying habit may remain, these strategies reduce the chances of ‘bad’ behaviours from occurring automatically." 

Dr Lally adds:  

"In principle, if you can't avoid your habit cues or make the behaviour more difficult, swapping out a bad habit for a good one is the next best strategy. It's much easier to do something than nothing, and as long as you're consistent, the new behaviour should become dominant over time, overpowering any impulses arising from your old habit."

SUBJECT OF RESEARCH

ARTICLE TITLE

Reports of 'death' of impulsivity as personality trait are likely exaggerated



CHINESE ACADEMY OF SCIENCES HEADQUARTERS





We can all act on an impulse, with some seemingly doing it more often and others less. Psychologists have been studying impulsivity as a personality trait since the 1930s and have linked impulsivity to a variety of harmful behaviors, such as violence and excessive use of social media, as well as mental disorders, such as bipolar disorder and substance use disorder. 

A study by a research team led by Dr. LUAN Shenghua from the Institute of Psychology of the Chinese Academy of Sciences (CAS) has provided comprehensive evidence that impulsivity is a stable, measurable, and predictive personality trait. 

The study, one of the largest in the field, disagrees with the pessimistic view that research on impulsivity is fraught with problems, including inconsistencies in its definition and a lack of reliable measurement tools. 

It was published online in PNAS on June 3. 

A total of 1,676 participants took part in the study. Each completed 48 impulsivity measures derived from 10 self-report scales and 10 behavioral tasks. The participants also reported the frequency of seven impulsivity-related behaviors, such as impulsive buying and social media use. 

Using advanced psychometric methods, the researchers found a general factor of impulsivity, I, in this large-scale data. Factor I is similar to the general factor g in intelligence and represents the common component shared by a wide range of impulsivity measures. 

According to the researchers, factor was stable over time—in fact, it was the most stable of all measures over a three-month interval—and was good at predicting impulsivity-related behaviors, as evidenced by analysis using machine learning algorithms. 

Based on their data and modeling results, the researchers further developed a new scale, the Adjustable Impulsivity Scale (AIMS), to measure impulsivityAIMS has excellent psychometric properties that are largely retained in shorter versions and is quite effective with only 10 measurement items. 

"These results show that impulsivity is a valid and useful psychological construct for differentiating people. To paraphrase Mark Twain, reports of the death of impulsivity may have been greatly exaggerated, and this construct is still very much alive," said Dr. LUAN, corresponding author of the study. 

The discovery of the general impulsivity factor I and the development of the new AIMS scale are the two most notable contributions of this study. They significantly advance the conceptualization and measurement of impulsivity and facilitate the application of impulsivity as a personality trait in both clinical and non-clinical contexts. 

The study was supported by the National Natural Science Foundation of China and the Institute of Psychology of CAS. 

 

Florida infection preventionist successfully advocates for staff growth, keeping pace with hospital’s expanding service lines



Creative approach, diversified IPC roles create onramp for non-traditional staff


Meeting Announcement

ASSOCIATION FOR PROFESSIONALS IN INFECTION CONTROL





San Antonio, Texas, June 4, 2024 – In an era of hospital budget cuts and staffing freezes, a Florida hospital more than doubled staff positions for infection prevention and control (IPC) over a four-year period, reducing infections and creating opportunities for non-clinical team members to enter the field and excel.

By presenting a business case showing costs of excess healthcare-associated infections (HAIs), infection preventionist (IP) Luz Caicedo, MPH, CPH, CIC, CRCST, VA-BC at AdventHealth in Celebration, Florida was able to increase IPC staff from 2 to 4.8 full-time equivalents (FTEs) and decrease HAIs and communicable disease exposures between 2019 and 2023, according to an oral abstract being presented today at the 2024 APIC Annual Conference. She also created an IPC career ladder with diversified roles, outlining career progression and enhancing retention among the team.

When Caicedo joined AdventHealth in 2019, there were just two full-time equivalent IPs on staff and the 217-bed Florida hospital was in the midst of an expansion to accommodate 357 beds, in addition to bringing on more operating rooms, catheterization labs, interventional radiology, endoscopy, and ambulatory sites. Already understaffed and unable to visit operating rooms or ambulatory sites more than a few times a year, Caicedo knew she needed to expand IP capacity to adequately protect patients and staff from HAIs.

To assess the resources necessary to provide adequate coverage and build her business case, she based her ideal IP staffing ratio not just on the number of inpatient beds, but also on the hospital’s growing number of procedural areas and outpatient service lines, using the 2012 New York State Acute Care Bed equivalent as a model.

Starting with surgical site infections (SSIs), she was able to convince hospital leaders to let her hire a new IP to cover the surgical service. When SSIs decreased markedly, she received approval for additional staff. As a result of expanding the size of the IP team from 2 in 2019 to 4.8 FTEs in 2023, AdventHealth Celebration achieved a 37% decrease in CLABSIs, and a 45% decrease in healthcare-onset C. difficile as the hospital increased its operations.

“Our Chief Nursing Officer is very supportive of the IPC department because we've been able to show her results,” said Caicedo. “Every time that she has invested IPC staff positions, we’ve been able to lower our infection rates.”

With approval to grow the department came the challenge of determining the type of positions to bring on. To address this, Caicedo created an IPC career ladder and diversified the roles in the department to include an entry-level IP Associate and IP Coordinator, as well as Infection Preventionist, and IP Manager. This structured career progression has enhanced retention and has created pathways for non-clinical team members to enter the field.

Additional staffing has allowed the IPC team to introduce quality improvement initiatives like building dashboards to track device rounds, launching a ‘CAUTI bootcamp’ which has dramatically reduced catheter-associated urinary tract infections, and working with the lab to lower blood culture contamination rates.

“The work that the AdventHealth IPC team is undertaking and the success they have achieved would be impossible without proper staffing,” said Tania Bubb, PhD, RN, CIC, FAPIC, 2024 APIC president. “Their success is a testament to the support received from hospital leaders and also to Luz’s ability to demonstrate that investment in infection prevention can impact the whole facility. Tools like the APIC IP Staffing Calculator and the one that Luz used can help facilities quantify IPC staffing needs to make the case for adequate resources.”

The oral abstract, “Advancing Infection Prevention: Navigating Staffing Growth and Implementing a Career Ladder (LDPM 16)” is being presented at 1:41pm CT, June 4, at the APIC Annual Conference in San Antonio, Texas. 

Surgical site infection rates and other secondary outcomes decrease dramatically at multi-state hospital system through standardized, preoperative, surgical, antibiotic practices



Improved outcomes for orthopedic, colorectal, and abdominal hysterectomy surgery patients



ASSOCIATION FOR PROFESSIONALS IN INFECTION CONTROL




San Antonio, Texas, June 4, 2024 – Mortality, length of stay, readmissions, and surgical site infections (SSI) all declined after a six-state hospital system implemented a comprehensive surgical site infection (SSI) prevention bundle, according to a report presented today at the 2024 APIC Annual Conference.

Banner Health, which operates facilities in Arizona, California, Colorado, Nebraska, Nevada, and Wyoming, reported on the impact of a surgical antimicrobial prophylaxis (SAP) bundle on more than 57,000 surgical cases from January 2019 to December 2023. Four publicly reportable procedures were included in the analysis: hip and knee arthroplasty, colorectal surgery, and abdominal hysterectomy.

The infection prevention (IP) team at Banner Health began delving into an all-encompassing clinical practice for SSI prevention in 2019 with the goal of reducing their Standardized Infection Ratios (SIRs). It was determined that focusing on one bundle component, specifically SAP across all 30 of their facilities, could have the greatest impact on SSI reduction. As part of the intervention, they monitored adherence to the appropriate selection of preoperative antibiotics, dose, administration times, and redose. Starting from a baseline of 67.1% in 2019, adherence to this process measure increased to 82.2% by 2023.

During the same period, compliance with the SAP bundle produced the beneficial effect of shortening length of stay (LOS) by 4 days, decreasing overall mortality rates by 4.4%, and lowering the average 30-day readmission rates by 3.9%. Similarly, compliance with the SAP bundle in hip arthroplasty procedures evidenced a statistically significant (p<0.0001) reduction in average 30-day readmission rates from 11% to 7%.

“This work shows that a bundle of evidence-based interventions designed to reduce infections can also impact other important outcomes like mortality, length of stay, and readmissions,” said Aarikha D'Souza, BS, MPH, CIC, FAPIC, clinical practice lead and infection prevention regional director at Banner Health. “If we’re sending patients home earlier there’s a ripple effect as we also decrease the chances of them developing deep vein thrombosis, pneumonia, pressure injuries, or having a fall.”

Increased adherence to the SAP bundle illustrated the most benefit among orthopedic patients. Hip arthroplasty procedures resulted in a statistically significant 32.8% decrease in SSI rates and 48.3% drop in SIR, while knee arthroplasty procedures resulted in a 15.2% reduction in SSI rates and 33.1% decrease in SIR. Additionally, adherence to the SAP bundle in colorectal surgeries and abdominal hysterectomy procedures decreased SSI rates by 17.4% and SIR by 8.11%, respectively.

“This project shows the value of intense focus on a specific set of process measures to influence not just infection rates, but also other important quality metrics,” said Tania Bubb, PhD, RN, CIC, FAPIC, 2024 APIC president. “We are grateful to Banner Health for their exceptional patient safety work and for sharing their success at the APIC Conference.”

The oral abstract, “Effect of a Standardized Preoperative Prophylactic Antimicrobial Guideline on Improved Postoperative Surgical Site Infection (SSI) Outcomes,” (ISR 11) is being presented at 2:30 pm CT, June 4, at the APIC Annual Conference in San Antonio, Texas.

Marmarth, ND – Three keen-eyed young fossil hunters made the discovery of a lifetime when they found the remains of a rare teenage Tyrannosaurus rex that could rewrite history, scientists and filmmakers announce today. 

The boys -- brothers Liam and Jessin Fisher, 7 and 10 years old at the time, and their 9-year-old cousin, Kaiden Madsen -- spotted a large fossilized leg bone on a walk in the Hell Creek badlands area of North Dakota on July 31, 2022.

Believing they had found a relatively common duckbill dinosaur, they sent a photo to family friend and Marmarth native Dr. Tyler Lyson, Associate Curator of Vertebrate Palaeontology at the Denver Museum of Nature & Science, who organized an excavation that began 11 months later, adding the boys and a sister, Emalynn Fisher, now 14, to his team of palaeontology volunteers and experts. 

Brushing off a tooth soon after arriving, Dr. Lyson realized the boys had found a notorious T. rex -- a very rare juvenile specimen. The team unearthed it in 11 days after an estimated 67 million years in that spot.

Airlifted onto a truck by a Black Hawk helicopter, giant plaster jackets containing the “Teen Rex” are now at the Denver Museum of Nature & Science, where the public will be able to follow the fossil’s preparation in the new “Discovering Teen Rex Prep Lab.” 

Remarkably, the secret of the teenage T. rex find held for nearly two years while an award-winning documentary crew, renowned palaeontologists, several of the world’s foremost natural history museums, and top animators partnered to present the kids’ discovery in dramatic cinematic fashion.

A crew from Giant Screen Films (GSF), a world-leading producer of large-format documentaries, was embedded with expedition and had 8K cameras rolling as the fossil’s diagnostic features were unearthed, including the eureka moment when Dr. Lyson confirmed that the kids had found a Tyrant King. 

As a result, audiences can experience the adventure of the discovery and excavation through an immersive new giant screen documentary, T. REX, narrated by New Zealand actor Sir Sam Neill, who portrayed Dr. Alan Grant in the Jurassic Park films. 

With hat tips to famous specimens, landmark discoveries, and wild cinematic depictions over the last century, GSF’s documentary intercuts the remarkable expedition with cutting edge computer graphics that bring the iconic T. rex—from hatchling to hulking adult—to life on the world’s largest screens. 

Extremely rare juvenile T. rex

‘Juvenile rex specimens are extremely rare,” said Dr. Lyson, who found his first dinosaur in the same area at age 6. He credits his own career to the mentorship of paleontologists who invited him to join their work in the Badlands. 

“This find is significant to researchers because the ‘Teen Rex’ specimen may help answer questions about how the king of dinosaurs grew up,” he said.

The size of the specimen’s tibia (shin bone), 82 cm, compared to the size for a full grown adult’s tibia (112 cm) suggests that it was 13 to 15 years old when it died around 67 million years ago.

Paleontologists also estimate that “Teen Rex” likely weighed around 3,500 pounds (1,632 kg), measured roughly 25 feet (7.6 m) from nose to tail, and stood about 10 feet (3 m) in height—about two-thirds the size of a full grown adult.

“It’s remarkable to consider how T. rex might have grown from a kitten-sized hatchling into the 40-foot, 8,000 pound adult predator we are familiar with,” said Dr. Thomas Holtz, a vertebrate paleontologist from the University of Maryland and renowned T. rex authority. 

He continued, “scientists can really only speculate on how ‘Teen rex’ might have lived and behaved, so discoveries like this one have the potential to provide important new information about those earlier life stages, when fastest growth likely occurred.” 

The experience was especially exciting for Jessin, a dinosaur aficionado and aspiring paleontologist who dressed up as his hero, Dr. Tyler Lyson, for Halloween a few years ago. 

And “helping these kids experience the thrill of their discovery and to be inspired by science is incredibly rewarding to me personally,” said Dr. Lyson, who was himself mentored by leading paleontologists visiting the area when he was very young. 

The boys are keen to visit the “Teen Rex Prep Lab” when it opens and the film debuts in Denver June 21. They are also excited about a later film screening for Marmarth schoolmates to share the thrill of their discovery. 

With Dr. Holtz as lead advisor, the T. REX filmmakers collaborated with a consortium of paleontologists, eight prominent natural history museums, and award-winning visual effects artists to create scientifically accurate models of rex and the Hell Creek prehistoric ecosystem, a highly studied rock formation in the Upper Midwest that contains fossil remains from the Late Cretaceous, the final days of the dinosaurs—from Triceratops to Edmontosaurus. 

Supported by a coalition of leading museums worldwide, the documentary features cameos of SUE, perhaps the most well-known T. rex specimen ever found (Field Museum, Chicago); T. rex WYREX (Houston Museum of Natural History); T. rex THOMAS (Los Angeles Natural History Museum) and HORRIDUS the Triceratops (Melbourne Museum). 

A dream documentary story

“We never could have planned the inspiring story that unfolded in front of the cameras,’ said producer and writer Andy Wood. “Kids finding any large dinosaur is remarkable, but as the shoot progressed, the team realized that we were witnessing something even more rare—a truly historic T. rex discovery. It’s been a real thrill.” 

"This is more than just a documentary—it's a chance for families to experience the thrill of discovery through the eyes of these young explorers in a format that makes you feel like you’re right there with them,” says co-director/writer David Clark.

“This is the kind of story that documentary filmmakers dream of capturing.”

“Beyond fostering an appreciation of the fun of science, the film sends a message about getting outside and exploring,” said Dr. Lyson. “That’s a really important message that we want to come through—one that I think is just baked into this story.”

T. REX will premiere at select theatres worldwide beginning June 21, opening in 100 cities over the coming months in all immersive museum cinema formats, including large format, IMAX, 3D, and giant dome. 

GSF has also partnered with Rextooth Studios to create a graphic novel to accompany the film.

Discovering a ‘Teen Rex’ is extremely rare and may help reveal how the king of dinosaurs grew up.

While invasive alien species have long been recognised as a major threat to nature and people, urgent action now is needed to tackle this global issue. This is the critical evaluation by the 88 authors, representing 101 organisations from 47 countries, of ‘Curbing the major and growing threats from invasive alien species is urgent and achievable’ published in Nature, Ecology & Evolution, including lead author Professor Helen Roy from the UK Centre for Ecology & Hydrology and the University of Exeter.

Focused on the main findings of the Intergovernmental Science Policy Platform on Biodiversity and Ecosystem Services (IPBES) thematic assessment report on invasive alien species and their control*, the paper also highlights that the impacts of invasive alien species observed today are likely to underestimate the magnitude of future impacts. Also, the interactions among biodiversity drivers are key as no driver acts in isolation.

Co-chair of the IPBES IAS assessment and lead author, Professor Helen Roy from the UKCEH and the University of Exeter, said: “The paper brought together the entire expert team of the IAS assessment, with this diverse group spanning many disciplines with perspectives from around the world drawing the same conclusion about the need for urgent action on the major and growing threat of invasive alien species.

“With the number of invasive alien species set to rise, the IPBES invasive alien species assessment provides the evidence-base and options to inform immediate and ongoing action. To achieve this there is a need for collaboration, communication and cooperation, not only across borders but within countries.”

Professor Peter Stoett from Ontario Tech University, co-chair of the IPBES IAS assessment, added: “Interdisciplinarity is key to the success of IPBES assessments. It was wonderful to see social science and humanities experts interacting with invasion biologists and other natural scientists, in a community-building process that will inform policy decisions moving forward.”

The threats posed by invasive alien species are expected to continue to rise. Every year, approximately two hundred new alien species are now being introduced globally by human activities to regions they had not been recorded before. Even without the introduction of new species by human activities, already established alien species will continue to naturally expand their geographic ranges and spread into new countries and regions, with many causing negative impacts. Simple extrapolations from the impacts of invasive alien species observed today are likely to underestimate the magnitude of future impacts.

Interactions among drivers of biodiversity loss are amplifying biological invasions with no driver acting in isolation. Climate change is a major driver facilitating the establishment and spread of invasive alien species into previously inhospitable regions. For example, climate warming is enabling aquatic and terrestrial invasive alien species to establish and spread poleward, including into the Arctic and Antarctic regions. Also, in some mountainous regions, climate change, acting together with other drivers of biodiversity loss, has allowed invasive alien species to extend their ranges into higher elevations twice as fast as native species.

The IPBES invasive species assessment provided the first comprehensive synthesis of evidence globally concluding that the threat of biological invasions is major but can be mitigated with urgent cross-sectorial cooperative and collaborative action. Co-developing management actions with multiple stakeholders including government and private sector stakeholders, and Indigenous Peoples and local communities will be critical to achieving success in addressing biological invasions.

Aníbal Pauchard, co-chair of the IPBES IAS assessment and Professor at the University of Concepción, Chile, highlights the importance of inclusion within the assessment: “This is not only the most comprehensive global assessment on invasive alien species to date, but also the selection of experts and the evidence gathering was done under the highest standards of inclusivity, resulting in a report which provides critical insights for all stakeholders.”

Coordinating bodies such as the Non-Native Species Secretariat can ensure effective collaboration among diverse stakeholder groups. Indeed, management actions in response to incursions of the Asian hornet (Vespa velutina) in the UK have involved multiple stakeholders coming together to ensure rapid flow of information following detection of the species leading to effective control of nests.

The paper recognises that the engagement of the general public through awareness raising campaigns, education and community science platforms also contributes to establishing shared responsibilities in managing biological invasions. Community science initiatives, supported by digital identification tools are important for the rapid detection of invasive alien species. Records submitted by the public through the Asian Hornet Watch app in the UK are making a major contribution to Vespa velutina (Asian hornet) early warning and rapid response.

  • The unique stone tools were made of flint from the Mountains of Samaria, which were probably also the fallow deers' calving areas, located east of the prehistoric sites of Jaljulia and Qesem Cave. Consequently, the researchers hypothesize that Mounts Ebal and Gerizim were held sacred by prehistoric hunters as early as the Paleolithic era.

 

  • The researchers: "The new stone tools had a working edge shaped as scales, useful for a range of tasks in butchering and processing fallow deer. When the elephants disappeared from the region, the ancient hunters were forced to make technological adaptations, enabling them to shift their focus to hunting, butchering, and processing the light-footed fallow deer."

 

A new study from Tel Aviv University identified the earliest appearance worldwide of special stone tools, used 400,000 years ago to process fallow deer. The tools, called Quina scrapers (after the site in France where they were first discovered), were unearthed at the prehistoric sites of Jaljulia and Qesem Cave. They are characterized by a sharp working edge shaped as scales, enabling users to butcher their prey and also process its hides. The researchers explain that after the elephants disappeared from the region, the ancient hunters were forced to make technological adaptations enabling them to hunt, butcher, and process much smaller and quicker game - fallow deer. The study also found that the unique tools were made of non-local flint procured from the Mountains of Samaria, which probably also served as the fallow deers' calving area, about 20km east of Jaljulia and Qesem Cave. Consequently, the researchers hypothesize that Mounts Ebal and Gerizim (near Nablus of today) were considered a source of plenty and held sacred by prehistoric hunters as early as the Paleolithic period. The study was led by Vlad Litov and Prof. Ran Barkai of Tel Aviv University’s Jacob M. Alkow Department of Archaeology and Ancient Near Eastern Cultures. The paper was published in Archaeologies.

 

The researchers explain that for about a million years, starting 1.5 million years ago, early humans used stone tools called scrapers to process hides and scrape the flesh off the bones of mostly large game. In the Levant they mainly hunted elephants and other large herbivores that provided most of the calories they needed. The study found, however, that about 400,000 years ago, following the elephants' disappearance, hunters turned to a different kind of prey, considerably smaller and quicker than elephants - fallow deer.

 

Litov explains: "In this study we tried to understand why stone tools changed during prehistoric times, with a focus on a technological change in scrapers in the Lower Paleolithic, about 400,000 years ago. We found a dramatic change in the human diet during this period, probably resulting from a change in the available fauna: the large game, particularly elephants, had disappeared, and humans were forced to hunt smaller animals, especially fallow deer. Clearly, butchering a large elephant is one thing, and processing a much smaller and more delicate fallow deer is quite a different challenge. Systematic processing of numerous fallow deer to compensate for a single elephant was a complex and demanding task which required the development of new implements. Consequently, we see the emergence of the new Quina scrapers, with a better-shaped, sharper, more uniform working edge compared to the simple scrapers used previously."

 

The study relies on findings from an excavation at the Jaljulia prehistoric site next to Highway 6 in central Israel, probably inhabited by humans of the homo erectus species, as well as evidence from the nearby Qesem Cave. At both sites the excavators discovered many scrapers of the new type, made of non-local flint whose nearest sources are the western slopes of Samaria, to the east of the excavated sites, or today's Ben Shemen Forest to the south.

 

Prof. Barkai adds: "In this study we identified links between technological developments and changes in the fauna hunted and consumed by early humans. For many years researchers believed that the changes in stone tools resulted from biological and cognitive changes in humans. We demonstrate a double connection, both practical and perceptual. On the one hand, humans started making more sophisticated tools because they had to hunt and butcher smaller, faster, thinner game. On the other, we identify a perceptual connection: Mounts Ebal and Gerizim in Samaria, about 20km east of Jaljulia, were a home range of fallow deer and thus considered a source of plenty. We found a connection between the plentiful source of fallow deer and the source of flint used to butcher them, and we believe that this link held perceptual significance for these prehistoric hunters. They knew where the fallow deer came from and made special efforts to use flint from the same area to make tools for butchering this prey. This behavior is familiar from many other places worldwide and is still widely practiced by native hunter-gatherer communities."

 

Litov concludes: "We believe that the Mountains of Samaria were sacred to the prehistoric people of Qesem Cave and Jaljulia, because that's where the fallow deer came from. It's important to note that in Jaljulia we also found numerous other tools made of different kinds of locally-procured stones. When the locals realized that the elephant population was dwindling, they gradually shifted their focus to fallow deer. Identifying the deer's plentiful source, they began to develop the unique scrapers in the same place. This is the earliest instance of a phenomenon that later spread throughout the world. The new scrapers first appeared at Jaljulia on a small scale, about 500,000 years ago, and a short time later, 400,000 to 200,000 years ago, on a much larger scale at Qesem Cave. The Samarian highlands east of Jaljulia and Qesem Cave were likely the home range of a fallow deer population, as evidenced by bone remains recovered from local archaeological sites throughout the Pleistocene and Holocene. Many fallow deer bones were also found at the altar site on Mount Gerizim, attributed in the Old Testament to Joshua bin Nun, and identified by some traditions as the place of Abraham's Covenant of the Pieces described in the Book of Genesis. Apparently, the Mountains of Samaria gained a prominent, or even sacred status as early as the Paleolithic period and retained their unique cultural position for hundreds of thousands of years."

Optimism wards off procrastination


Believing that the future will not be more stressful than the present could help procrastinators achieve more

People with an optimistic outlook on the future are less likely to be severe procrastinators, according to new research at the University of Tokyo. While procrastinators often admonish themselves for their “bad habit,” it turns out that their worries for the future are more to blame. Through a survey of nearly 300 young people, researchers found that those who had a positive view about their stress levels decreasing in the future, compared to the past or present, were less likely to experience severe procrastination. Views on personal well-being didn’t appear to have an effect. Improving people’s outlook and readiness for the future could help them overcome procrastination and achieve a less stressful lifestyle. 

How many times have you made a “to do” list, and although the most important task is at the top, you seem to be working your way up from the bottom or distracted by something else entirely? While we might chide ourselves for procrastinating, sometimes the more we try to overcome it, the more stressed we feel and the cycle continues. That is how it was for graduate student Saya Kashiwakura from the Graduate School of Arts and Sciences at the University of Tokyo, so she decided to investigate why.

“I have struggled with procrastination since childhood. I would clean my room when I needed to study for a test and prioritize aikido practice over my postgraduate research. This habit of putting off important tasks has been a constant challenge,” said Kashiwakura. “I wanted to change my behavior, as I realized that I was not confronting the future impact of my actions.”

This inspired Kashiwakura to examine the relationship between procrastination and the procrastinator's perspective on time, particularly their view of the future. When she began researching procrastination, she was surprised to discover that many more people suffer from it than she had imagined and found it reassuring her problems were not unique.

Previous research has shown that a feature of procrastination is disregard for the future or difficulty linking present actions with future outcomes. However, the reasons for this have been unclear. Kashiwakura and co-author Professor Kazuo Hiraki, also from UTokyo, proposed that it might be because severe procrastinators have a more pessimistic outlook. 

The researchers surveyed 296 participants in Japan in their 20s for their views on stress and well-being, and importantly how these changed over time. This included asking about their experiences from 10 years in the past through to the present, and their expectations for 10 years in the future. From the results, participants were clustered into one of four groups (for example, if they thought their situation would improve or would stay the same), and then each group was divided into severe, middle and low procrastinators. 

“Our research showed that optimistic people — those who believe that stress does not increase as we move into the future — are less likely to have severe procrastination habits,” explained Kashiwakura. “This finding helped me adopt a more light-hearted perspective on the future, leading to a more direct view and reduced procrastination.” 

It was not only the level of stress people experienced, but how their perception of it changed over the 20-year time period discussed, which influenced their procrastination habits. Surprisingly, a relationship wasn’t found between procrastination and negative views on well-being, such as one’s attitude towards oneself, or not yet finding purpose and goals in life.

Using these results, the team wants to develop ways to help people nurture a more optimistic mindset and overcome procrastination. “We hope our findings will be particularly useful in the education sector. We believe that students will achieve better outcomes and experience greater well-being when they can comprehend their procrastination tendencies scientifically, and actively work on improving them, rather than blaming themselves,” said Kashiwakura. 

“Thoughts can change with just a few minutes of watching a video or be shaped by years of accumulation. Our next step is to investigate which approach is appropriate this time, and how we can develop the ‘right’ mindset to lead a happier and more fulfilling life.”
