Memory, Sleep and dreaming

Getting Some Sleep Doesn’t Make Eyewitnesses Any Better At Identifying Suspects

Person Pointing at a Police LineupBy Emily Reynolds

We tend to think of sleep as a positive thing. Not enough of it, and we suffer: our moods drop, and we find it harder to both concentrate on what’s in front of us and remember what’s happened. Being well-rested, on the other hand, is associated with greater ability to communicate, to achievement at home and at work, and to superior recollection of previously learned facts or events.

Based on what we already know about the benefits of sleep on memory it may seem obvious that going to bed would also help eyewitnesses identify those they had seen perpetrate crimes. But in a new study, published in Royal Society Open Science, researchers found no such association: it was confidence, not being well-rested, that made a difference.

Memory, Methodological

Public Belief In “Memory Myths” Not Actually That Widespread, Study Argues

The general public has a pretty poor understanding of how memory works — and lawyers and clinical psychologists can be just as bad. At least, this is what many researchers have asserted, notes a team at University College London in a new paper, published in the Journal of Experimental Psychology. However, their research reveals that the idea that most people ignorantly subscribe to “memory myths” is itself a myth.

The wording of earlier studies, and also discrepancies in how memory experts and the general public tend to interpret the meaning of statements about memory, have painted a bleaker picture of public understanding than is actually the case, according to a series of studies led by Chris Brewin. This has important implications for cases in which ideas about memory are highly relevant — among jurors in a court room, for example.

Faces, Memory

Timing Is Crucial For Creating Accurate Police Sketches From Eyewitness Descriptions

A witness to a crime has to describe the offender’s face in as much detail as they can before they work with a police expert to create a visual likeness — a “facial composite”, sometimes called a photo-fit, or e-fit. But the way this is typically handled in police stations could be reducing the accuracy of these images, according to a new paper published in the Journal of Experimental Psychology: Applied.

There have been concerns that the process of describing facial features might create a so-called “verbal overshadowing” that interferes with the visual memories of the offender. Recent work had suggested that waiting half an hour before starting on the composite should allow this predicted over-shadowing to fade away, and so make for a better composite. However, the new research, led by Charity Brown at the University of Leeds, has found that in more real-world situations, a delay actually makes things worse.

Alcohol, Memory

Drinking Alcohol Focuses Our Attention On The External Features Of Faces, With Implications For Eyewitness Memory

Having a bit of a fuzzy memory is not an uncommon side effect of having had too much to drink the night before — and the details we do remember are often somewhat limited. The same can also be true for our attention when drunk: we’re only able to concentrate on what’s going on in front of us and not what’s happening elsewhere.

This phenomenon has been termed “alcohol myopia”: attentional shortsightedness related to alcohol consumption. A new paper in the Journal of Psychopharmacology suggests this shortsightedness may apply to human faces, too — and that it could have an impact on how well people can identify perpetrators of crimes they witness while drunk.

Using Fidget Spinners May Actually Impede Learning

Though fidget spinners have been around since the early 1990s, it was 2017 when they really started to make a stir, becoming a seemingly overnight sensation and starting to appear in offices, classrooms, public transport and pretty much anywhere else they were permitted. The actual provenance of the design has been debated, but many companies market the toys as a tool for concentration, particularly for those who have anxiety, ADHD or autism.

Calming — and fun — they may be, but do they actually work when it comes to keeping attention? Julia S. Soares & Benjamin C. Storm from the University of California, Santa Cruz think not. In a new paper, they look at the marketing of fidget spinners as attentional aides — and come to the conclusion that they may be actively distracting.

Simply Imagining Other People Can Change Our Own Sense Of Self

“The sense of self is a hallmark of human experience. Each of us maintains a constellation of personal memories and personality traits that collectively define ‘who we really are'”.

So begins a new paper, published in the Journal of Experimental Psychology, which reveals that who you “are” can easily be manipulated. Just imagining somebody else can alter all kinds of aspects of how you see yourself, even including your personality and memories.

Five Unusual, Evidence-Based Ways To Get Better At A New Language

GettyImages-1037536210.jpgBy Emma Young

The last time I tried to learn a foreign language, I was living in an Italian suburb of Sydney. My hour a week at a local Italian class was inevitably followed by a bowl of pasta and a few glasses of wine. As an approach to language-learning goes, it was certainly more pleasurable than my German lessons at school. Despite the wine, it was also surprisingly effective. In fact, getting better at a new language doesn’t have to mean hard hours on lists of vocab and the rules of grammar. It turns out that what you don’t focus on matters, too. And a glass of wine may even help …

Preliminary Evidence That Stress Makes Negative Memories Less Distinctive, With Implications For Witness Testimony

By Matthew Warren

Stress has complicated effects on our memories. Whereas some studies have found that we are better at remembering events that occurred during stressful situations, such as while watching disturbing videos, others have shown that stress impairs memory. Now a study published in Brain and Cognition suggests that stress doesn’t influence the strength of our emotional memories at all. Instead, the researchers claim, it is the fidelity of those memories – how distinct and precise they are – that changes when we go through stressful experiences.

Memory, The self

First Systematic Study Of The Advice People Would Give To Their Younger Selves

By Christian Jarrett

The question is an old favourite – if you could travel back in time, what advice would you give to your younger self? Yet despite the popularity of this thought experiment, no one has, until now, actually studied what people would tell themselves.

Reporting their findings in The Journal of Social Psychology Robin Kowalski and Annie McCord at Clemson University have done just that in two surveys of hundreds of participants on Amazon’s Mechanical Turk website. Their findings show that people’s advice to their younger selves is overwhelmingly focused on prior relationships, educational opportunities and personal worth, echoing similar results derived from research into people’s most common regrets in life. Moreover, participants who said they had followed the advice they would give to their younger selves were more likely to say that they had become the kind of person that their younger self would admire. “…[W]e should consult ourselves for advice we would offer to our younger selves,” the researchers said. “The data indicate that there is much to be learned that can facilitate wellbeing and bring us more in line with the person that we would like to be should we follow that advice.”

Teenagers Define Themselves Mostly In Terms Of Their Positive Traits; Adults More In Terms Of Their Social Roles

Write down the unfinished statement “I am …” twenty times. Now think to yourself “Who am I?” and complete as many of the “I am …” statements as you can in the next five minutes or less.

This is the Twenty Statements Test and it’s designed to assess how we see ourselves – our “self-concept”. For their new paper in the journal Memory, a team at the University of Reading, led by Emily Hards, gave this test to 822 teenagers (aged 13-18) from three schools in England, with the additional instruction “not to think too much about the responses and not to worry about the order/importance of the statements”.

While it’s widely recognised that adolescence is a crucial period for the establishment of our sense of self, little is actually known about how teenagers’ generally see themselves. Indeed, this is the first time that teenagers’ own self-generated descriptions of themselves (what the researchers call their “self-images”) have been gathered in a systematic way.
