Flexible predictive processing during face perception

This study investigates how sex/gender stereotypes influence face perception by manipulating expectations during emotion and sex categorization tasks, revealing task-dependent effects on neural coding and behavior.

Multiple-Demand Network encoding geometry balances generalization and dimensionality during novel task assembly.

The paper investigates how the brain encodes novel task instructions using fMRI and finds that the MDN uses both abstract and high-dimensional coding to balance generalization and expressivity.

Selection vs. integration task demands shape the similarity of information neural coding

This study examines how selection and integration demands during a size judgment task influence neural coding patterns using EEG, revealing differences in categorical and exemplar encoding.

Novel verbal instructions recruit abstract neural patterns of time-variable information dimensionality

This study uses EEG to examine how neural patterns dynamically represent and reconfigure information during novel verbal instruction tasks, revealing changes in dimensionality and abstraction over time.

High-intensity physiological activation disrupts the neural signatures of conflict processing

This study examines how high physical activation affects neural markers of cognitive control, finding no significant behavioral impact but unreliable neural measures.

Concurrent response and action effect representations across the somatomotor cortices during novel task preparation.

The paper investigates how instructions pre-activate motor and perceptual neural states in somatomotor cortices during novel task preparation, finding pre-activation of response-related templates in action control regions.

Proactive selective attention across competition contexts

This study investigates how anticipated competition levels modulate preparatory brain activity and task performance using EEG and MVPA in a sex judgment task.

Context-dependent neural preparation for information relevance vs. probability

This study uses fMRI and multivariate decoding to show that neural preparation for stimulus relevance and probability involves distinct brain regions with some overlap in the fusiform gyrus.

The effect of task demands on the neural patterns generated by novel instruction encoding

This study investigates how implementation and memorization demands affect neural encoding of task-relevant variables during novel instruction processing using fMRI and multivariate analyses.

Representational organization of novel task sets during proactive encoding.

This study uses fMRI and representational similarity analysis to examine how brain regions organize novel task encoding based on control-related variables and reward expectations.

Transient and sustained control mechanisms supporting novel instructed behavior.

This study extends the dual model of cognitive control to novel instructed tasks, showing both fronto-parietal and cingulo-opercular networks are involved in transient and sustained control mechanisms.
