Your Level Of “Planfulness” Could Determine How Often You Visit The Gym

Cycling Class at the Gym

By Matthew Warren

When a gym recently opened up near my house, I was determined to go regularly and make the most of the facilities. And I did — for about a month. But gradually, my visits became fewer and further between, until I realised I was paying for a bunch of machines and slabs of metal that I hadn’t touched in weeks. Guiltily, I cancelled my membership.

But perhaps I have my personality to blame. A new study tracking gym users has honed in one key factor that is related to how often they visit: their “planfulness”. This aspect of our personality, say the researchers, could be “uniquely useful” for predicting a range of goal-directed behaviours.

When False Claims Are Repeated, We Start To Believe They Are True — Here’s How Behaving Like A Fact-Checker Can Help

By Matthew Warren

If you hear an unfounded statement often enough, you might just start believing that it’s true. This phenomenon, known as the “illusory truth effect”, is exploited by politicians and advertisers — and if you think you are immune to it, you’re probably wrong. In fact, earlier this year we reported on a study that found people are prone to the effect regardless of their particular cognitive profile.

But that doesn’t mean there’s nothing we can do to protect ourselves against the illusion. A study in Cognition has found that using our own knowledge to fact-check a false claim can prevent us from believing it is true when it is later repeated. But we might need a bit of a nudge to get there.

Distinct From IQ Or Working Memory, “Implicit Learning Ability” Is An Important, Stable Trait That Varies Between Individuals

The striking findings have implications for our understanding of intelligence

By Emma Young

There’s a huge amount of research into how people differ in their ability to learn things deliberately and “explicitly”, such as memorising a list of words or instructions, for example. Far less studied is “implicit learning”. Ask a five-year-old to explain the grammatical rules of their language and they’ll likely have no clue where to start. And yet, they do know them – or at least, well enough to form coherent sentences. This kind of unconscious acquisition of abstract knowledge is an example of “implicit” learning. 

Implicit learning may be especially important for young children, but adults depend on it, too. It “is recognised as a core system that underlies learning in multiple domains, including language, music and even learning about the statistical structure of our environments,” note the authors of a new paper, published in Cognition.

Higher Intelligence And An Analytical Thinking Style Offer No Protection Against “The Illusory Truth Effect” – Our Tendency To Believe Repeated Claims Are True

It’s a trick that politicians have long exploited: repeat a false statement often enough, and people will start believing that it’s true. Psychologists have named this phenomenon the “illusory truth effect”, and it seems to come from the fact that we find it easier to process information that we’ve encountered many times before. This creates a sense of fluency which we then (mis)interpret as a signal that the content is true.  

Of course, you might like to believe that your particular way of thinking makes you immune to this trick. But according to a pre-print uploaded recently to PsyArXiv, you’d be wrong. In a series of experiments, Jonas De keersmaecker at Ghent University and his collaborators found that individual differences in cognition had no bearing on the strength of the illusory truth effect.

Most Comprehensive Review To Date Finds The Average Person’s Reading Speed Is Slower Than Previously Thought

giphyBy Matthew Warren

You should take just under two-and-a-half minutes to finish reading this blog post. That’s going by the findings of a new review, which has looked at almost 200 studies of reading rates published over the past century to come up with an overall estimate for how quickly we read. And it turns out that that rate is considerably slower than commonly thought.

Of the various estimates of average reading speed bandied around over the years, one of the most commonly cited is 300 words per minute (wpm). However, a number of findings of slower reading rates challenge that statistic, notes Marc Brysbaert from Ghent University in Belgium in his new paper released as a preprint on PsyArxiv.

Researchers Were Surprised To Find Bungee Jumpers’ Cognition Was Enhanced After A Jump

It’s well-established in psychology that intense emotion and physiological arousal interfere with people’s ability to think straight. Most theories explain this in terms of anxiety consuming mental resources and focusing attention on potential threats. Although it’s tricky to study this topic in the psych lab, a handful of field studies involving parachutists and emergency simulations have largely supported this picture. However, a team at the Autonomous University of Barcelona believe that not enough consideration has so far been given to what they call the “valence” of intense situations – whether or not the person sees the intense experience as positive or negative. To find out whether this makes a difference, Judit Castellà and her colleagues tested dozens of bungee jumpers (most of them first-timers) three times: 30 minutes before a 15M free fall jump; immediately afterwards; and again eight minutes after that. 

The surprising findings, reported in Cognition and Emotion, suggest that when an intensely arousing experience is perceived positively, it may actually enhance cognition rather than be impairing. “Although we expected some degree of moderation, that is, an attenuation of the negative impact of high arousal reported in the literature, we did not predict an actual improvement or a total lack of impairment,” the researchers said.

Taking Tiny Breaks Is Key To Learning New Skills

A wealth of research has shown that taking breaks is an important part of learning. Resting straight after acquiring new information seems to improve memory of that information, for example, and sleep is particularly important for consolidating what we have just learned. 

Now it seems that even miniscule breaks, just seconds long, are also vital for learning new skills. A study published recently in Current Biology has found that most of the improvement while learning a motor task comes not while actually practicing, but instead during the breaks between practice sessions.

Being Prompted To Think About Coffee Elevates Your Physiological Arousal And Focuses Your Mind, No Ingestion Required

So entrenched is the association in our culture between coffee and ideas of arousal, ambition and focus that merely thinking about, or being reminded of, the drink is enough to increase the body’s arousal levels, in turn provoking a more focused, literal cognitive style. That’s according to Eugene Chan at Monash University and Sam Maglio at the University of Toronto Scarborough who, reporting their findings in Consciousness and Cognition, write that “… people may be more aroused simply after walking by a coffee shop. Not only would they be more aroused, but at a more downstream level, their decision making might shift as well.”

The intriguing results come from four studies involving hundreds of online and lab-based participants, but given the replication problems in the general area of “social priming” (concerned with how abstract ideas and sensory experiences can influence thoughts and behaviour, and vice versa), some readers may find that merely hearing about this new research is enough to elevate their pulse and alter their mindset to a more sceptical mode.

The Ninja Brain: Humans Can Prioritise Meaningful Sounds Even While Asleep

We often think of sleep as a chance to switch off from the outside world, leaving us blissfully ignorant of anything going on around us. But neuroscience research has shown this is a fantasy – we still monitor the environment and respond to particular sounds while we’re sleeping (at least in some stages of sleep) – a fact that will be unsurprising to anyone who has woken up after hearing someone say their name.

Now a study published in Nature Human Behaviour has revealed more about the brain’s surprisingly sophisticated levels of engagement with the outside world during sleep. Not only does the sleeping brain respond to certain words or sounds – it can even select between competing signals, prioritising the one that is more informative.

Trait Neuroticism As “Mental Noise” – Neurotic People Have Noisier, More Chaotic Minds, Say Researchers

Of the main personality traits, Neuroticism (characterised by emotional instability and lack of resilience) is probably the one with the least going for it. High scorers on this trait are impulsive, tend to worry a lot, and they struggle with low moods and short tempers. Thanks to personality research, we know a lot about what lies in store for people who score high on Neuroticism, such as increased risk of mental health problems and relationship turmoil. But as Robert Klein and Michael Robinson note in their new paper in Journal of Personality we know a lot less about the psychological processes that underlie the trait. From an emotional perspective, neurotic people are said to be more sensitive to threat and punishment, but what about the cognitive side? Across four studies, Klein and Robinson present evidence consistent with what they call the mental noise hypothesis – “neurotic people have noisier, more chaotic mental control systems”, they write.
