A child's popularity is related to where the teacher seats them in the classroom

Teacher training doesn't usually include a module on how to arrange the seating of pupils. Perhaps it should - a new study by psychologists finds that where children are placed in the classroom is associated with how well-liked they are by their classmates.

Yvonne van den Berg and Antonius Cillessen studied 34 classrooms at 27 elementary schools in The Netherlands. The 336 participating pupils had an average age of 11, and 47 per cent of them were boys. In all classrooms, it was the school policy that the teachers dictated who sat where; seating arrangements were in groups or rows, or a mixture. Every pupil was asked to say how much they liked each of their classmates, and to rate their classmates' popularity. They gave these ratings twice: four to six weeks into the first semester (August/September time), and then again at the beginning of the school's second semester during the following Spring.

A key finding was that children who were seated in the first semester near the boundaries of their classroom tended to be less liked by their peers at that time, and also six months later, as compared with children sat nearer the centre of the class. Another related result was that children tended to rate those located nearer to them as more likeable and more popular (this helps explain the first result - children sat centrally tend to have more classmates closer to them). Meanwhile, children who were only (re)positioned at the boundaries of the class in the second semester did not receive lower likeability ratings at that time, presumably because their reputation had already been established by then.

Why should seating position have these associations with children's perceptions of their peers? The researchers think two psychological mechanisms are pertinent. Social psychology research on race relations and prejudice finds that the more we interact with other people, the more positive our views of them tend to be. School pupils naturally interact and socialise more with the children located near to them, and so this interaction could encourage more positive perceptions. There is also a psychological phenomenon known as the "mere exposure effect", which describes how familiarity with something or someone breeds more positive feelings towards them.

Van den Berg and Cillessen also conducted a second study with 158 more school children, in which they asked them to rate each others' popularity, and also to say where they would position themselves and their classmates if they could choose. Perhaps unsurprisingly, children said they'd like to sit nearer to their peers who were more liked and more popular. The researchers said this provided an insight into what's known as the "cycle of popularity" - well-liked and popular children typically attract more social interactions with others, this then reinforces the popular perception that others have of them via the mechanisms mentioned earlier.

There are plenty of unknowns in this research. For example, we don't know the reasoning behind the teachers' decisions of where they chose to locate their pupils in their class. Perhaps they placed more popular pupils more centrally? In fact, there are reasons to think this unlikely - past research has found teacher and pupil ratings of pupils' social relationships are only weakly related.

Despite the unknowns, the van den Berg and Cillessen said their results provided evidence for what's been termed the "invisible hand of the teacher" - the understudied ways that teacher decisions influence the ecology of the classroom. "Classroom seating arrangements may be hugely influential in children's exposure to and interactions with other peers and, thus, in determining children's social relationships with one another," the researchers concluded. They also highlighted that this new research builds on another recent study they conducted, which found that placing children closer to each other in the classroom improved pupils' liking of each other and reduced problem behaviours in class.

Is being a worrier a sign of intelligence?

We usually see worry as a bad thing. It feels unpleasant, like a snake coiling in the pit of your stomach. And worriers are often considered weak links in a team - negative influences who lack confidence. But of course, anxiety has a useful function. It's about anticipating and preparing for threats, and learning from past mistakes.

Increasingly psychologists are recognising the strengths of anxious people. For example, there's research showing that people more prone to anxiety are quicker to detect threats and better at lie detection. Now Alexander Penney and his colleagues have conducted a survey of over 100 students and they report that a tendency to worry goes hand in hand with higher intelligence.

The researchers asked the students to complete measures of worry, anxiety, depression, rumination, social phobia, dwelling on past social events, mood, verbal intelligence, non-verbal intelligence, and test anxiety. This last measure was important because the researchers wanted to distinguish trait anxiety from in-the-moment state anxiety and how each relates to intelligence.

The key finding was that after controlling for the influence of test anxiety and current mood, the students who reported a general habit of worrying more (e.g. they agreed with survey statements like "I am always worrying about something") and/or ruminating more (e.g. they said they tended to think about their sadness, or think "what am doing to deserve this?") also tended to score higher on the test of verbal intelligence, which was taken from the well-known Wechsler Adult Intelligence Scale. To take one specific example, verbal intelligence correlated with worry proneness with a statistically significant value of .19 (after controlling for test anxiety and mood), explaining an estimated 46 per cent of the variance in worry.

Another result, not so promising for worriers, was that a tendency to dwell on past social events was negatively correlated with non-verbal intelligence (that is, those students who dwelt more on past events scored lower on non-verbal IQ).

Seeking to explain these two different and seemingly contradictory correlations, the researchers surmised that: "more verbally intelligent individuals are able to consider past and future events in greater detail, leading to more intense rumination and worry. Individuals with high non-verbal intelligence may be stronger at processing the non-verbal signals they interact with in the moment, leading to a decreased need to re-process past social encounters."

Of course we must be careful not to over-interpret these preliminary results - it was a small, non-clinical sample after all, so it's not clear how the findings would generalise to people with more extreme anxiety. However it's notable that a small 2012 study found a correlation between worry and intelligence in a sample diagnosed with generalised anxiety disorder. Penney and his colleagues concluded that: "a worrying and ruminating mind is a more verbally intelligent mind; a socially ruminative mind, however, might be less able to process non-verbal information."

Want to learn something better? Draw it

When you're trying to learn, do something with your new knowledge, such as summarising it or explaining it to someone else. This deepens your memories and helps integrate what you've learned with what you already knew. A new study has tested the benefits of another beneficial learning activity - drawing.

Annett Schmeck and her team asked 48 German school-kids (average age 14) to read a 850-word passage about the biology of influenza, broken down into seven paragraphs. This was an unfamiliar topic to the teens, and they knew they were going to be tested on the content afterwards.

Crucially, half the pupils were asked to produce a drawing for each of the paragraphs, to depict visually the content of the paragraphs. They were assisted by a basic background image of a cell (or similar), and a legend showing basic components their drawing should include, such as an antibody. The other pupils only had the text to study and they acted as a control group. All participating pupils worked at their own pace.

There were two tests on the scientific text: a multi-choice comprehension test, and a drawing test that involved drawing key concepts from the text. The group who'd produced drawings while they were learning out-performed the control group on both the multiple-choice (scoring 61 per cent correct on average vs. 44 per cent) and the drawing test (scoring 52 per cent on average vs. 28 per cent).

This first experiment has some obvious limitations that Schmeck and her team sought to address in a follow-up involving 168 more pupils (average age 14). Most importantly, the researchers showed that drawing each paragraph of the to-be-learned text led to superior test performance (63 per cent correct on multiple choice, on average), even when compared to a condition in which pupils were instead provided with drawings produced by the author of the scientific text  (53 per cent correct). The better the pupils' drawings, the more successful they were in the tests afterwards.

The researchers said that drawing has this benefit for learning because it "encourages learners to engage in generative cognitive processing during learning such as organising the relevant information into a coherent structure, and integrating it with relevant prior knowledge from long-term memory."

The results come with a number of caveats - the study material in this research was scientific and involved a causal chain of events. It's not clear if drawing will also help people learn other kinds of content. Moreover, the tests took place right after the learning phase, so it's not known if the benefits of drawing will be long-lasting. Also, it's worth noting that this research looked at assisted drawing - that is, the pupils were given a background image to draw upon and told what graphic elements to include. The researchers concluded: "drawing during learning appears to be a potentially powerful strategy for improving students' learning from scientific text when certain boundaries and prerequisites are taken into account."

Why do friendly people usually lead happier lives?

High scorers on the personality trait of agreeableness are eager to please, concerned for others, and compliant to other perspectives. On average, they live happier lives too. A new study suggests a possible reason: when they have the chance, friendly people tend to avoid engaging with negative things.

The researchers, Konrad Bresin and Michael Robinson, began by asking participants to view a series of positive and negative images, spending as much time as they wanted on each one. Most people lingered longer on the nasty images, but participants high in agreeableness showed no such tendency. This effect persisted through two experiments involving around 200 student participants, and also generalised to another setup, where 73 participants had to indicate whether they would prefer to engage in a fun or unpleasant pastime. Examples included: an upbeat happy song or a slow sad one; a documentary profiling a famous entertainer or one on government corruption; or a lecture on how to bake a cake versus one on dissecting a body. Low-agreeableness participants were equally likely to go for a negative experience as a positive one, whereas the high agreeableness ones showed a strong preference for the positive: anthems, nation's sweethearts and shortbreads.

Although it's unlikely this finding would generalise to very negative situations, Bresin and Robinson argue that the bulk of real-life experiences tend to fall within more narrow boundaries - slightly nicer or less pleasant situations. And across many of these situations, people differing in agreeableness will fork out on more positive life routes. Previous research has looked at how people of different outlooks may respond to challenging events differently: when life gives you lemons, optimists make lemonade. This research suggests agreeable people are more likely to amble past lemon-groves into the orchard next door.

Rapport-building interrogation is more effective than torture

Past research (pdf) suggests that using torture as a way to extract information or confessions from terror suspects isn't just unethical, it's also ineffective. The advantage of rapport-building interrogation strategies (including respect, friendliness and empathy towards suspects) over more coercive techniques is highlighted once again in a new study that involved interviews with law enforcement interrogators and detainees.

The research involved 34 interrogators (1 woman) from several international jurisdictions including Australia, Indonesia and Norway. And there were 30 international detainees (1 woman), most of whom had been held on suspicion of terrorism, including people suspected of involvement with the Tamil Tigers or the Islamist group Ansar al Ismal based in Norway. One in five of the detainees reported being subjected to practices that constitute torture. Note, these were separate groups - the interrogators had not dealt professionally with the participating detainees.

The research team led by Jane Goodman-Delahunty asked the interrogators and detainees to recall a specific interrogation session, to describe the interrogation practices used, and the outcomes in terms of information shared, cooperation and confessions. The results were striking - disclosure was 14 times more likely to occur early in an interrogation when a rapport-building approach was used. Confessions were four times more likely when interrogators struck a neutral and respectful stance. Rates of detainee disclosure were also higher when they were interrogated in comfortable physical settings. More surprising, cooperation reduced five-fold when detainees were presented with explicit evidence. It's possible this is because interrogators were more likely to resort to presenting evidence to uncooperative detainees.

The researchers said their results "augment the accumulating cross-national consensus about effective noncoercive best practices in investigative interviewing." Their hope is that this will "reduce practitioner skepticism about reliance on noncoercive interview strategies with high value detainees." Of course the study is limited in some ways, especially regarding its reliance on people's memories of prior interrogations, and the fact that the detainees' doubtless have a vested interest in highlighting the effectiveness of rapport-based strategies.
