To predict the behaviour of a primate, would you rather base your guess on a closely related species or one with a similar brain shape? We looked at brains & behaviours of 70 species, you’ll be surprised!

Food choices are always a tradeoff between the benefits of energy intake and the risk of accidental contamination. The relative importance of these two varies depending on a person's current metabolic need. (1/3)
Sensitivity to contamination of food odours depends on hunger and attention
Detection of deviant notes in food odours protects against accidental contaminant ingestion, but this risk needs to be weighed against the potential c…

Today, the ERC formally adopted a decision to increase its support for researchers moving to Europe.

On top of its normal grants, the ERC offers 'start-up' funding to help PIs establish laboratories / research teams in Europe.

This extra funding is now x2 (up to €2 million!)

🧠✨ New insights on motor imagery:
Motor imagery doesn't just mimic actual movement in the brain — it can also enhance the performance of different, linked movements.
Congrats, Magda ;D

His study showed that temporal expectations can have opposing effects on reaction times and perceptual accuracy in touch. It also emphasizes the importance of collecting both metrics and integrating comp. modelling to understand how temporal expectations influence perceptual decision-making.

Using an hierarchical DDM, Ziliang showed that temporal expectations actually shortened non-decision times but reduced the drift rate (evidence accumulation) for expected versus unexpected or neutral forces: high correlations between the empirical data and simulated!

In contract, temporal expectations accelerated reaction times! Control analyses showed that these effects could not be explained by speed-accuracy trade offs...

Crucially, by having a neutral block where force onset was not linked to the tone, he confirmed that the effects were caused by expectation itself, rather than the expectation violation. These results indicate that expectation hinder tactile perception!

His two experiments revealed that temporal expectations consistently impaired participants’ ability to accurately judge the intensity of forces. This impairment was evident across behavioural metrics, including JND and d-prime in Experiment 1, as well as accuracy in Experiment 2.

To address these inconsistencies, he used a temporal cueing paradigm, associating auditory tones with the onset of tactile stimuli to induce temporal expectations. He quantified tactile discrimination accuracy, threshold, sensitivity, perceived intensity (Exp 1 and 2), and speed (Exp 2).

He reasoned that discrepancies maybe stem from variations in methodologies and perceptual metrics across studies. For example, some studies focus on reaction times, while others prioritise accuracy or discriminability.
