Cross-task stability refers to performance consistency across different settings and measures of the same construct. Cross-task stability can help us understand developmental processes, including how risks such as preterm birth affect outcomes. We investigated cross-task stability of attention control in 32 preterm and 39 term infants. All infants had the same chronological age at time of testing (5 months) but varied in gestational age (GA) at birth (30-42 weeks). Infants completed an experimental attention following task with a researcher and a naturalistic play observation with their mothers. Both preterm and term infants demonstrated attention following in the experimental task. GA and flexibility of attention were related: the likelihood of no turn trials decreased with increasing GA. To evaluate cross-task stability, we compared attention performance in the experimental and naturalistic settings. Flexible attention shifts on the experimental task were positively related to attention to objects in the naturalistic observation. Furthermore, the association between flexible attention shifts on the experimental task and attention to objects in the naturalistic observation was moderated by GA. Our study provides initial evidence that the consolidation of attention control increases with GA. These findings highlight the value of comparing experimental and observational measures of attention.

Difficulties with executive functioning are implicated in various forms of psychopathology. However, executive functioning task performance frequently demonstrates poor test-retest reliability, questionable convergent validity, and unstable associations with clinical measures. Model-based approaches may improve measurement by providing richer information about mechanisms underlying performance.

The brain's temporal dynamics across large-scale networks are essential to understanding cognitive processes. However, a coherent framework remains elusive due to the combinatorial complexity of sequential states and methodological inconsistencies across studies. Here, we address these challenges by identifying a limited set of brain-wide signal propagation modes that capture diverse spatiotemporal features reported across studies.

Reading a book in a coffee shop requires focusing on the task at hand and ignoring task-irrelevant distraction (cognitive stability), while setting aside the book to answer a phone call requires the ability to switch between tasks (cognitive flexibility). Stability and flexibility are often conceptualized as opposing ends of a one-dimensional stability-flexibility continuum, whereby increasing stability (prioritizing task focus) reciprocally reduces flexibility (a readiness to switch tasks), and vice versa. Recent evidence, however, has supported a two-dimensional stability-flexibility relationship, whereby stability and flexibility can be maintained at high levels simultaneously when necessary.

The research of class-incremental semantic segmentation (CISS) seeks to enhance semantic segmentation methods by enabling the progressive learning of new classes while preserving knowledge of previously learned ones. A significant yet often neglected challenge in this domain is class imbalance. In CISS, each task focuses on different foreground classes, with the training set for each task exclusively comprising images that contain these currently focused classes.

Dual-functional stability (DFS) in cognitive and physical abilities is important for successful aging. This study examines the brain topology profiles that underpin high DFS in older adults by testing two hypotheses: (1) older adults with high DFS would exhibit a unique brain organization that preserves their physical and cognitive functions across various tasks, and (2) any individuals with this distinct brain topology would consistently show high DFS. We analyzed two cohorts of cognitively and physically healthy older adults from the UK (Cam-CAN, n = 79) and the US (CF, n = 48) using neuroimaging data and a combination of cognitive and physical tasks.
