…and this is the personality trait that keeps you thin…
The disorder affects between 1 and 6% of the population.
The disorder affects between 1 and 6% of the population.
People with Borderline Personality Disorder experience very stormy emotions, commit self-destructive acts and are sometimes aggressive.
Often considered the most severe personality disorder, Borderline Personality Disorder is linked to a long history of instability in personal relationships.
The personality disorder causes very strong mood swings as a result of brain abnormalities in two key regions, according to a host of neuroscience studies.
Dr Lars Schulze, the study’s first author, said:
“Our results highlight brain abnormalities in the amygdala and the dorsolateral prefrontal cortex.
The amygdala is known to process emotional arousal and is hyperactive in BPD.
The dorsolateral prefrontal cortex, which has a key role in the regulation of emotions, is less active during the processing of negative emotional stimuli in BPD.”
The researchers pooled the results of 19 different studies including hundreds of people, to compare those with the personality disorder to health controls.
Professor John Krystal, Editor of Biological Psychiatry, explained the brain abnormalities they found:
“In order to understand these findings, it might be useful to imagine that the brain was a like a car.
The gas pedal for emotion might be the amygdala and the emotional brake might be the dorsolateral prefrontal cortex.
The current findings seem to suggest that, in borderline personality disorder, the brain steps on the gas yet does not as effectively brake emotion.”
The study was published in the journal Biological Psychiatry (Schulze et al., 2016).

Perfectionism in mind, body and career is on the rise in the young, new research finds.
The current crop of college students is more obsessed with being perfect than they were 30 years ago.
Making comparisons on social media could be one important driver for the rise in perfectionist tendencies.
The change could be having a dramatic negative effect on their mental health.
Dr Thomas Curran, the study’s first author, said:
“Meritocracy places a strong need for young people to strive, perform and achieve in modern life.
Young people are responding by reporting increasingly unrealistic educational and professional expectations for themselves.
As a result, perfectionism is rising among millennials.”
The study included 41,641 people from the US, Canada and Britain.
All were asked about three types of perfectionism:
Between 1989 and 2016, the type that had increased the most was socially prescribed — that which is imposed by society (up by 33%).
Other-oriented had increased 16% and self-oriented by 10%.
Dr Curran said:
“These findings suggest that recent generations of college students have higher expectations of themselves and others than previous generations.
Today’s young people are competing with each other in order to meet societal pressures to succeed and they feel that perfectionism is necessary in order to feel safe, socially connected and of worth.”
Competition among young people may be harming them, the researchers think.
There is competition over grade point averages, careers and how they look.
In the face of these pressures it can be hard to maintain good mental health.
This may help to explain why levels of depression, anxiety and suicidal thoughts are higher among young people than a decade ago.
The study was published in the journal Psychological Bulletin (Curran & Hill, 2017).
The psychological traits linked to achieving old age.
The psychological traits linked to achieving old age.
Psychologists studying a group of Italians aged 90 to 101 have found they share certain psychological traits.
These include being stubborn, domineering and needing a sense of control.
This might suggest you need a determined attitude to make it through to 100-years-old.
Professor Dilip V. Jeste, who led the study, said:
“The main themes that emerged from our study, and appear to be the unique features associated with better mental health of this rural population, were positivity, work ethic, stubbornness and a strong bond with family, religion and land.”
The 29 Italians the psychologists interviewed live in nine villages in the Cilento region of Southern Italy.
They were all asked a wide range of questions.
Dr Anna Scelzo, the study’s first author, said:
“The group’s love of their land is a common theme and gives them a purpose in life.
Most of them are still working in their homes and on the land.
They think, ‘This is my life and I’m not going to give it up'”.
The study found that although the nonagenarian’s physical health had deteriorated, they were in better mental health than family members four decades younger.
Here are some direct quotes from the study interviewees:
- “I lost my beloved wife only a month ago and I am very sad for this. We were married for 70 years. I was close to her during all of her illness and I have felt very empty after her loss. But thanks to my sons, I am now recovering and feeling much better. I have four children, ten grandchildren and nine great-grandchildren. I have fought all my life and I am always ready for changes. I think changes bring life and give chances to grow.”
- “I am always thinking for the best. There is always a solution in life. This is what my father has taught me: to always face difficulties and hope for the best.”
- “I am always active. I do not know what stress is. Life is what it is and must be faced … always.”
- “If I have to say, I feel younger now than when I was young.”
Dr Scelzo summarised the psychological traits linked to achieving old age:
“We also found that this group tended to be domineering, stubborn and needed a sense of control, which can be a desirable trait as they are true to their convictions and care less about what others think.
This tendency to control the environment suggests notable grit that is balanced by a need to adapt to changing circumstances.”
The study was published in the journal International Psychogeriatrics (Scelzo et al., 2017).
No, it’s not intelligence! How could you think such a thing?
No, it’s not intelligence! How could you think such a thing?
Mothers value outgoing personalities in their children above intelligence, new research finds.
Apparently, Mom prefers a little show-off to a smarty-pants!
Dr Sophie von Stumm, study co-author, said:
“Given that higher levels of intelligence and conscientiousness are both linked to positive life outcomes such as success at school, at work, and in relationships, it’s surprising that only 1 in 10 mothers valued them as the most important characteristics for their child.”
The results come from a survey of 142 mothers of young babies in the UK.
Over half chose extraversion as the top trait they desired in their children.
Dr von Stumm said:
“While extraversion can have many benefits it is also associated with negative behaviours in adulthood, such as higher alcohol consumption and illegal drug use.
Understanding how mothers view personality is vital as their values influence their parenting and, through this, how their child’s personality traits develop.”
Agreeableness was the second most-desired personality trait for their children, followed by openness to experience, intelligence and conscientiousness.
Unsurprisingly, no mother wanted a neurotic baby.
Dr Rachel Latham, the study’s first author, said:
“We focused on the views of mothers, as they typically spend more time with their children than fathers, but it would be useful to examine the personality values of fathers too.
It would also be interesting to examine if mothers’ preference for extraversion changes over time as children grow older and enter formal education.
“In the long run we hope studies such as these can help us to understand how parents’ values shape a child’s personality and how this impacts on how children develop and learn and their future health, happiness, and success.”
The study was published in the journal Personality and Individual Differences (Latham & von Stumm, 2017).

Do you hang your toilet roll with the end of the paper hanging ‘over’ or with the end hanging ‘under’?
According to a survey by Dr Gilda Carle, ‘over’ people are more assertive.
Assertive people are more likely to be in leadership roles and to have a take-charge attitude, says Dr Carle.
Those hanging the roll ‘under’ are more likely to be submissive.
Submissive people tend to be more agreeable, flexible and empathetic, says Dr Carle.
To create the toilet paper personality test, Dr Carle surveyed around 2,000 people of all ages, asking them whether they rolled the paper over or under.
Some people, Dr Carle has found, actually switched the toilet roll in other people’s houses (around one in five).
Naturally it was those ‘over’ people imposing their dominant personality on submissive ‘unders’.
Rolling under might also be linked to lower earnings, another survey has found.
73% of those earning under $20,000 rolled under, while 60% of those earning over $50,000 roll over.
(Who knew there were so many surveys on toilet roll alignment?)
Note: this survey was not published in a reputable peer-reviewed journal!
There are three things that naturally happen to people’s personality with age.
There are three things that naturally happen to people’s personality with age.
People get nicer as they get older, in contrast to the stereotype of the grumpy senior.
The finding may be a surprise to those that believe people never change.
They do — even if only a little.
The three main changes to personality that occur, on average, with age are that people get:
The study examined the brain scans of 500 volunteers.
The researchers found that typical changes in brain structure that occur with age were linked to changes in personality.
Dr Roberta Riccelli, the study’s first author, said:
“Our work supports the notion that personality is, to some degree, associated with brain maturation, a developmental process that is strongly influenced by genetic factors.”
These changes in personality suggest a genetic influence, explained Professor Nicola Toschi, a study co-author:
“Of course, we are continually shaped by our experiences and environment, but the fact that we see clear differences in brain structure which are linked with differences in personality traits suggests that there will almost certainly be an element of genetics involved.
This is also in keeping with the notion that differences in personality traits can be detected early on during development, for example in toddlers or infants.”
Dr Luca Passamonti, a study co-author, said:
“Linking how brain structure is related to basic personality traits is a crucial step to improving our understanding of the link between the brain morphology and particular mood, cognitive, or behavioural disorders.
We also need to have a better understanding of the relation between brain structure and function in healthy people to figure out what is different in people with neuropsychiatric disorders.”
The study was published in the journal Social Cognitive and Affective Neuroscience (Riccelli et al., 2016).

Better mental and physical functioning among people high in this personality trait.
Better mental and physical functioning among people high in this personality trait.
Optimists report higher levels of mental and physical functioning than pessimists, research reveals.
Not only that, but optimists also live longer.
Dr Toshihiko Maruta, the study’s first author, said:
“The wellness of being is not just physical, but attitudinal.
How you perceive what goes on around you and how you interpret it may have an impact on your longevity, and it could affect the quality of your later years.”
Researchers studied 447 people who were followed over 30 years.
Their personality was assessed, along with their physical and mental functioning.
It turned out that pessimists had a lower quality of life, on average.
Dr Maruta said:
“Our study provides documentation for beliefs commonly held by patients and health care practitioners about the importance of optimistic and pessimistic attitudes.
However, questions remain about the practical significance of these findings for health care practitioners.”
Naturally, though, the study cannot tell us if optimism causes these benefits or is a result of it.
Dr Maruta said:
“Explanatory style may have implications for prevention, intervention, health care utilization and compliance with treatment regimens.
Well formulated studies are essential to warrant the extra time, effort and costs associated with efforts to intervene in a patient’s explanatory style or to personalize the care specific to explanatory style.”
Previous research has also revealed that both extroverts and optimists are more likely to live longer than introverts and pessimists.
“Optimists have healthier hearts than pessimists, a new study of over 51,000 adults finds.
Optimists also had healthier body mass indexes, were more physically active and less likely to smoke.
Researchers found that the more optimistic people were, the greater their overall physical health.
The most optimistic people were 76% more likely to have health scores that were in the ideal range.”
The study was published in the journal Mayo Clinic Proceedings (Maruta et al., 2012).
Your personality can be read from your choice of smartphone.
Your personality can be read from your choice of smartphone.
Users of iPhones are more interested in their phone as a status object, new research finds.
Users of Android, though, the operating system from Google, were generally more honest and also less interested in wealth and status.
The results come from from a survey of 500 smartphone users.
It also revealed that iPhone users are:
Set against this, users of android phones were more likely to be:
Dr David Ellis, one of the study’s author, said:
“In this study, we demonstrate for the first time that an individual’s choice of smartphone operating system can provide useful clues when it comes to predicting their personality and other individual characteristics.”
Ms Heather Shaw, the study’s first author, said:
“It is becoming more and more apparent that smartphones are becoming a mini digital version of the user, and many of us don’t like it when other people attempt to use our phones because it can reveal so much about us.”
The study was published in the journal Cyberpsychology, Behaviour and Social Networking (Shaw et al., 2016).

How to fight the negative thinking at the heart of neuroticism.
How to fight the negative thinking at the heart of neuroticism.
Falling in love helps to stabilise the personalities of people who are neurotic, a study finds.
Love helps people who think pessimistically to approach life with more confidence and see events in a more positive light.
Neuroticism is explained by Dr Christine Finn, the study’s first author:
“Neurotic people are rather anxious, insecure, and easily annoyed.
They have a tendency towards depression, often show low self-esteem and tend to be generally dissatisfied with their lives.
However, we were able to show that they become more stable in a love relationship, and that their personality stabilizes.”
The researchers followed 245 couples aged between 18 and 30 over a period of 9 months.
They were asked how they would react to a series of fictitious scenarios and what they meant for their own relationships.
Being in a relationship helped neurotic people to see the world less negatively, the results showed.
Slowly but surely, as relationships blossomed, the neurotic people developed a more positive outlook.
The less neurotic partner also benefited from the changes, the researchers found.
Dr Finn said:
“The positive experiences and emotions gained by having a partner change the personality — not directly but indirectly — as at the same time the thought structures and the perception of presumably negative situations change.
[…]“It is difficult to reform a whole personality but our study confirms: Negative thinking can be unlearned!
Professor Franz J. Neyer, a study co-author, said:
“Of course everyone reacts differently and a long, happy relationship has a stronger effect than a short one.
But generally we can say: young adults entering a relationship can only win!”
