First Study To Investigate How Attachment Style Changes Through Multiple Decades Of Life

Attachment theory, which was first proposed in the 1950s by the British psychoanalyst John Bowlby, is one of the most influential in psychology. It argues for the importance of our earliest relationships with our caregivers, and predicts that these formative bonds will shape the nature of our connections with other people for the rest of our lives. Remarkably, however, psychologists still know relatively little about how people’s attachment style – essentially their characteristic style of relating to other people – typically varies through life. “How do attachment orientations change across the life span? Unfortunately … this critical question has eluded researchers,” write William Chopik and colleagues in their recently published paper in Journal of Personality and Social Psychology.

Their research is the first to document how attachment style varies, on average, through decades of the lifespan, from age 13 to 72. The results suggest that, like other aspects of personality, attachment style is relatively stable through life, but that it is not entirely fixed, and in particular that it may be shaped by our relationship experiences, as well as the varied social demands of different life stages. “The current study is one of the first truly longitudinal investigations into life span changes in attachment orientation and the antecedents of these changes,” write Chopik and his team.

Researchers Say Growing Up With A Troubled Or Harsh Father Can Influence Women’s Expectations Of Men, And, In Turn, Their Sexual Behaviour

The power (or powerlessness) of parents to shape their children for good or ill continues to preoccupy psychologists and the public alike. Among evolutionary-minded developmental psychologists, one specific idea is that girls’ later attitudes to relationships is influenced by their fathers’ behaviour. For instance, US research has found that girls with disengaged, harsh, and often absent fathers are known to start having sex at a younger age, and to have more sexual partners. However many questions about these findings remain. For example: might other aspects of the girls’ childhoods be involved; what about genetic effects; and which aspects of poor-quality fathering are the most consequential?  

A new study of pairs of sisters, published in Developmental Psychology, provides some specific answers, particularly that it is contact with a poor-quality father, not paternal absence, that affects their daughters’ later relationships, including their expectations of men, and, in turn, their sexual behaviour.

There Are Sex Differences In The Trajectory Of Depression Symptoms Through Adolescence, With Implications For Treatment And Prevention

By Matthew Warren

It’s well known that teenagers’ moods go through drastic changes. In particular, depressive symptoms – like feelings of low mood or self-loathing – tend to increase as they grow older. Now researchers have plotted out the exact trajectory of these depressive symptoms. In their recent paper in Journal of Youth and Adolescence, Alex Kwong and colleagues from the University of Bristol report for the first time the points during teen development when symptoms increase most rapidly, on average – and they find that these timings differ between young men and women.

In Later Life, We Become Less Aware Of Other People’s Anger And Fear, But Remain Sensitive To Their Happiness

Most people find it easy to infer the emotional state underlying a scowl or beaming smile. But not all facial emotional signals are so obvious. Sensitivity to these less obvious emotional signals varies from one person to another and is a useful skill, improving relations with other people and benefiting psychological wellbeing. As well as varying between individuals, are there also shifts in this ability during a typical person’s life? And, if so, might these age-related changes be relevant to known high-risk periods for psychological problems and the onset of mental illness? A new study, published in the Journal of Experimental Psychology, provides some answers.

These Violent Delights Don’t Have Violent Ends: Study Finds No link Between Violent Video Games And Teen Aggression

Claims that violent video games lead to aggression have been around since the days of Space Invaders. When young people are exposed to violent media, the theory goes, their aggressive thoughts become more prominent, leading them to commit acts of violence. But while several studies have found results that seem to back up this idea, the evidence is far from unequivocal.

Now a study published in Royal Society Open Science has failed to find any association between the time spent playing violent video games and aggressive behaviour, adding to a growing body of literature that suggests that such a link has been overstated – or may not exist at all.

Anyone who has stood in the supermarket aisle trying to remember their shopping list might have wished for a larger brain. But when it comes to memory, bigger isn’t always better. A study published in Neuropsychologia has found that young children whose cerebral cortex is thinner in certain areas also tend to have better working memory.

Researchers Explore A “Striking Phenomenon” In Young Children’s Thinking – Their Denial That Improbable Events Are Possible

Sure, it’s unlikely that a girl would ride a hippo or that a boy would drink onion juice, but as adults, we know that it’s not impossible. However, and in contrast to adults’ reasoning, for some time researchers have noticed a “striking phenomenon” (to quote the authors of a new paper) in young children’s thinking  – that is, up to around the age of eight, they frequently assume that improbable events are actually impossible. In their paper in Developmental Psychology, Celina Bowman-Smith at the University of Waterloo and her colleagues have investigated whether asking children to consider the possibility of hypothetical events in a distant, far away country might help them to overcome this closed-minded thinking and realise that improbable doesn’t mean impossible.

Time For A Fresh Approach To Learning Difficulties? The Cognitive Profile Of Kids Struggling At School Bore No Relation To Their Official Diagnoses

Around 30 per cent of British children fail to meet expected targets in reading or maths at age 11. These children face a future of continuing difficulties in education, as well as poorer mental health and employment success. Understanding why some kids struggle – and providing them with tailored support as early as possible – is clearly vital. Some will be diagnosed with a specific disorder, such as Attention Deficient Hyperactivity Disorder or dyslexia, and get targeted help. But many will not. And even many conventional diagnostic labels may be misleading, and fail to capture the true picture of a child’s problems, according to new work by a team at the MRC Cognition and Brain Sciences Unit at the University of Cambridge, which has come up with a radical, alternative approach.

Even two-year-olds can tell the difference between a leader and a bully

Every child is born into a world far more complex than the womb it departed. Physically it’s made up of objects, distances, heights, which we know new-born infants are already oriented to read and make sense of. But their new world is also a social one, chock-full of agents with needs and intentions, and past findings show that infants are surprisingly quick to recognise much of this too.  New research in PNAS adds to this literature, investigating the ability to make an important social distinction – between those who hold power due to respect and those who impose it through force – and finds that already by the time they are toddlers, infants can do this too.

Growth mindset doesn’t only apply to learning – it’s better to encourage your child to help, than to be “a helper”

Children primed to think of themselves as “helpers” were more discouraged when things didn’t go to plan

According to the Mindset Theory, if you tell a child repeatedly that they’re smart, it makes them less willing to push themselves when they get stuck on an intellectual challenge, presumably because failure would threaten their self-image of being a “smart kid”. For this reason, effort-based praise – rewarding kids for “working hard” rather than “being smart” – is widely recommended (though it’s not the same for adults). But does a similar effect occur in the social sphere? What if you ask a child – as so many parents and surely teachers do – to “be a helper” as if it’s a category that you either belong to or you don’t? 

Earlier research has found that young kids are more likely to try to help others when they are asked to “be helpers” instead of “to help”. But as Emily Foster-Hanson and her fellow researchers at New York University note, “Setbacks and difficulties are common features of children’s experience throughout development and into adulthood,” so it’s important to examine the effects of category labelling – like “being smart” or “being a helper” – when things go wrong for the child. And in their new paper, published in Child Development, they find that setbacks are more detrimental to a child labelled “a helper” than a child asked “to help”.
