Among many things, the man is terribly funny and doesn't hold back stirring up the Chomskyists 😂

Good point Maya. We may record some sections of the day, but we'll also want to make sure everyone is comfortable speaking up in discussions, and I can imagine recording the discussions may not feel comfortable for everyone. So I think we might record some talks but not all. Will let you know!

So, it will be a fascinating day of reckoning with "failure" as a normal part of science. The event is part of Mental Health Awareness Week, which is all about creating a positive research culture! Register for FREE online or in-person attendance here: www.eventbrite.co.uk/e/symposium-...

Why do we do this? Even the most successful researchers do not always succeed, so if we only focus on victories, we forego golden opportunities to learn from errors. As important, we reinforce biased impressions of others as being much more capable than ourselves. (2/3)

PS: all data, scripts, and *emotion induction stimuli* are accessible!

Thank you so much!

Several of you may have seen these results on a conference poster – you are not allowed to remind me of the year you saw it! But I am proud to finally be able to share it in writing. [fin]

Zooming out even more, the mood bias follows from a theoretical prediction we made about the role of mood in evolution. In simulations we showed that, due to correlations in the environment, an animal has foraging advantages when it follows its mood: www.sciencedirect.com/science/arti... [8/9]

This result is in line with our previous work where we demonstrated the same mood bias parameter to exist in studies of much slower mood fluctuations: www.nature.com/articles/s41....
Importantly, in this new study, we present results that cannot be subject to demand effects. [7/9]

Further proof of the existence of this ‘mood bias’ comes from RT (the costly option gets chosen faster when happy & slower when sad) and in gaze patterns (the costly option is inspected faster when happy; the uncostly option when sad). [6/9]

It was particularly exciting that we could ‘reconstruct’ mood purely with physiological valence and arousal markers. So, emotion ratings were not even necessary! Importantly, *physiological* mood bias and the *rated* mood bias were correlated. [5/9]

When modelling this effect, it could best be explained as follows: mood modulates a choice bias towards the costly but more rewarding option. We reproduced this finding in a confirmatory study. [4/9]

We found emotions on the mood continuum (happiness-neutral-sadness) to be associated with changes in economic choice. When happy, people sought larger rewards (in exchange for risk/delay/effort). When sad, people accepted smaller rewards that were safe/immediate/effortless. [3/9]

With text vignettes and music, we induced short (<1 min) states of happiness, sadness, anger, and fear. We validate the successful inductions with self-report and physiology: pupil dilation, skin conductance, facial musculature of the zygomaticus (😊 ) and corrugator (☹) [2/9]
