Too Hot To Handle: Men Who Eat Spicy Food Have More Testosterone

That’s what a new study, from researchers at France’s University of Grenoble, found in their new study titled “Some Like It Hot.” To test this correlation, they recruited 114 men aged 18 to 44 and asked them whether they preferred spicy food or not, then they gave the men a meal of mashed potatoes and provided them with either a spicy pepper sauce or regular table salt (a control seasoning). The men were then asked to report how spicy they felt their meals were, and the researchers measured levels of testosterone in their saliva. Men with the most testosterone were also the ones who liked the spicier potatoes.

“These results are in line with a lot of research showing a link between testosterone and financial, sexual, and behavioral risk-taking,” Laurent Begue, an author of the study, toldThe Telegraph. “In this case, it applies to risk-taking in taste.”

How behavioural science could revamp development

At the end of a hectic six days, Simon Ruda and Stewart Kettle took theirdata to the superintendent of the Guatemalan tax authority. The two men had spent several weeks redrafting letters sent to citizens, reminding them to pay tax. It looked like their efforts had generated a significant windfall for the cash-strapped Guatemalan administration. “When we showed these results to the superintendent he was just so happy,” says Kettle. 

Ruda and Kettle work for the Behavioural Insights Team, a social purpose company that began life as part of the UK Prime Minister’s Office. But its services were in such demand that it was spun out of government to become an independent company to allow it to expand more rapidly — the first time this has happened to a Whitehall policy team. The unit specialises in delivering ‘nudges’: tiny changes in how governments operate that make it more likely their citizens will behave in a certain way. 

For example, if a government wanted to promote healthy eating, it could introduce a law that everyone had to eat 100 grams of carrot every day. Or it could reduce any sales tax on carrots, encouraging people to buy them. 

But research has shown that another approach is often cheaper and more effective: arrange things so the behaviour you want to encourage is the easiest and most attractive option. In our healthy eating example, this might mean nudging children towards eating vegetables by simply asking schools to place them in front of the chips when serving lunch.

The causal inference of cortical neural networks during music improvisations

“We present an EEG study of two music improvisation experiments. Professional musicians with high level of improvisation skills were asked to perform music either according to notes (composed music) or in improvisation. Each piece of music was performed in two different modes: strict mode and “let-go” mode. Synchronized EEG data was measured from both musicians and listeners. We used one of the most reliable causality measures: conditional Mutual Information from Mixed Embedding (MIME), to analyze directed correlations between different EEG channels, which was combined with network theory to construct both intra-brain and cross-brain networks. Differences were identified in intra-brain neural networks between composed music and improvisation and between strict mode and “let-go” mode. Particular brain regions such as frontal, parietal and temporal regions were found to play a key role in differentiating the brain activities between different playing conditions. By comparing the level of degree centralities in intra-brain neural networks, we found a difference between the response of musicians and the listeners when comparing the different playing conditions.”
