Want to learn a new skill more effectively? Stop thinking about yourself!

The human mind can be its own worst enemy. When we want to do well in sports, we often intensify attentional focus on bodily movements that are best off left on automatic pilot. The result, even for elite athletes, can be a dire instance of choking. The muscles stiffen or shake. Fluid, expert movement is lost, and the learning of new skills is impaired.

A common assumption is that an internal focus is harmful to performance because it directs unhelpful conscious attention to bodily control. But what if the costs of self-focus are more general and profound than that? Perhaps merely thinking about ourselves in any way is harmful to performance and learning because to do so activates the “self-schema”.

The self-schema is “more than a philosophical construct” argue Brad McKay and his colleagues in a new paper, it is in fact a “functional neural network located anatomically in cortical midline structures.” Their theory is that anything that activates this network – be that over-focus on bodily movements, memories of past performance, or the scrutiny of an audience – will be detrimental to skilled performance and learning.

The researchers began by dividing 36 students (26 men) into two groups and asking them to throw 10 balls underarm at a bulls-eye style target. Throws nearer the target earned more points. Both groups performed equally well. Now one group spent a minute “thinking about their previous throwing experience including their strengths and weaknesses as a thrower”; the other group acted as controls and just waited out the time. Both groups then performed 10 more throws. The students who’d spent time thinking about themselves showed inferior performance compared with their earlier standard; the control group maintained their skill level.

“A simple manipulation designed to activate the self-schema … was sufficient to degrade performance,” the researchers said. 

Next, 37 more students were recruited (18 women) and split into two groups. They spent time practising using a bat to hit golf-ball-sized balls, travelling at 25mph, at a target. None of them had played organised baseball or softball in the last year.

Over two practice days, all the students completed a writing task in the various short breaks between hitting. Those in the self-reflective group wrote for one minute either about their experience at baseball; their personal attributes as an athlete; their emotional experiences related to baseball; or their strengths and weaknesses as a hitter (all the different topics were covered during the different breaks). The other group acted as controls – they spent the same breaks writing about objects in the laboratory where the training took place, either focusing on colours or shapes or the names of the objects.

A few days later, the students had a final go at the ball hitting challenge. Adjusting for initial performance differences, the control group significantly outperformed the self-reflective group. The control group also outperformed the self-reflective group when the task was changed slightly by speeding up the delivery of the balls.

McKay and his team said their results were surprising – as one of their participants remarked, you’d think spending time writing about one’s past glory days at baseball would have provided a confidence boost, and maybe rekindled old movement patterns too. Instead, the researchers said their results showed how the “ostensibly innocuous activity of contemplating one’s own experiences, emotions, strengths, weaknesses and attributes, might have activated a lurking neural self-network that interfered with the process of motor learning.”

Critics may feel this study raises as many questions as it answers – with no measures of muscle tension, or mood, or a myriad other possible mediating factors, we’re left in the dark about why writing about the self appeared to be detrimental to motor skill learning.

However, the researchers believe their study has broken new ground. Where previous research has shown instructions to focus on parts of the body can be harmful to performance, McKay and his team said their “experiments are the first to show that self-reflection alone is sufficient to interfere with motor skill activation and performance.”
