Bbe25-003	Efficient Learning of Predictive Maps for Flexible Planning
	Quote:	We show that SR-IS outperforms existing models in planning tasks and provides a better account of the graded biases in human replanning that previous models could not explain. This work bridges theories of predictive maps with observed planning behavior and offers new insights into flexible decision making in the brain.

Mpy25-006	Factor Analysing Predictive Processing: No Evidence for a General Factor Across Tasks
	Quote:	Background Hypothesis Dysfunctional predictive processing (PP), specifically the aberrant weighting of priors, is a frequently-proposed mechanism for psychosis and psychosis-like phenomena (schizotypy).... Conclusions These results do not evidence a single factor underpinning PP performance. It is therefore inappropriate to use results from single tasks to propose a generalised PP deficit in psychosis. Variation was also not captured by a two-factor hierarchical model of priors.

Mpy25-011	Dissociable Thalamocortical Circuit Disruptions During Contextual Fear Renewal in PTSD
	Quote:	Conclusions State-specific reductions in MDm-hippocampal-cingulate and pulvinar-vmPFC connectivity during early fear renewal in PTSD highlight parallel thalamocortical alterations during flexible contextual threat updating. These alterations, along with the selective MDm-dACC association with symptom severity, nominate MDm-centered circuit as a hypothesis-generating focus for future mechanistic neuromodulation studies.

	Quote:	Conclusions Social responsiveness assessed in early adolescence (age 11) were associated with sleep disturbance independent of multiple confounding factors and were prospectively associated with sleep disturbance at age 13 years. These findings contribute to the evidence that disruption of sleep and circadian timing may have a primary role in the mechanisms that mediate autistic traits.

	Quote:	DISCUSSION ADP exhibited accelerated cognitive decline across domains driven by a distinct biomarker landscape compared to non-psychotic AD. Plasma ptau181 demonstrated broader domain-specific associations with decline in ADP than other blood-based biomarkers and associated exclusively with executive function impairment, indicating its unique utility for predicting cognitive trajectories in this pathophysiological subtype.

	Quote:	Conclusions Serotonergic interventions robustly reduce perseverative thinking but do not consistently alter performance on laboratory measures of cognitive flexibility. These findings suggest that serotonin may influence cognitive-emotional rigidity and the subjective experience of repetitive thought more strongly than objective executive task performance. The dissociation between task-based and phenomenological outcomes aligns with contemporary models of serotonergic plasticity and highlights perseverative thinking as a potentially transdiagnostic therapeutic target of serotonergic interventions.

	Quote:	transdiagnostic dimensions revealed more coherent associations with higher-order cognition than symptom-level analyses, highlighting the added value of examining psychopathology at the factor rather than the symptom level. These findings portray a hierarchical view of cognitive dysfunctions in psychopathology and point to representational and metacognitive processes as potential targets for transdiagnostic intervention.
