Online Now: Rhythmic sampling of decision alternatives through attention
loading . . .
Rhythmic sampling of decision alternatives through attention
Recent work by Siems et al. shows that the brain rhythmically samples competing alternatives through covert spatial attention. This challenges continuous models of decision-making and suggests that evaluation is temporally structured by oscillatory dynamics, with attention determining when alternatives are accessed rather than reflecting changes in their representations.

Many of us were taught experiments are for testing hypotheses. In Ch 1 of Experimentology, our free, open methods textbook, my coauthors and I argue differently: experiments are for estimating the magnitude of causal effects. This reframing has important consequences. 🧵

The hidden cost of acute task switching as revealed in routine surgical practice
Nature Human Behaviour, Published online: 11 May 2026; doi:10.1038/s41562-026-02458-9To assess the real-world effect of task switching on expert performance, we analysed 316,742 organ transplants in the USA over a 13-year period. When surgeons switched between different organ types in consecutive surgeries, 1-year mortality rates in patients increased by 14.8% — effects that can be mitigated through structured scheduling and recovery time.

The paper shows that high‑gamma field activity and local spiking are distinct. The “hashy” signal often treated as a proxy for spiking is partly generated by other biophysics like dendritic and network‑level currents, not just summed spikes.

loading . . .
Consciousness indicators, mimicry, and internal variants
In a recent article on methods for assessing artificial intelligence (AI) systems for consciousness, we argued that computational properties of internal processing should be used as indicators [1]. Commenting on our proposal, Pennartz argues that this method ‘should be supplemented with behavioural-cognitive methods’ (p. 1) because there is no consensus theory of consciousness [2]. We agree that the lack of a consensus theory of consciousness makes it more important to use every available source of evidence, but in our article, we preferred internal over behavioural assessments on the grounds that the latter can be ‘gamed’ by AI systems.
