Context, not conflict, drives cognitive control [PDF]

, 2012
Theories of cognitive control generally assume that perceived conflict acts as a signal to engage inhibitory mechanisms that suppress subsequent conflicting information.

Cytosolic calcium regulates cytoplasmic accumulation of TDP-43 through Calpain-A and Importin α3

eLife, 2020
Cytoplasmic accumulation of TDP-43 in motor neurons is the most prominent pathological feature in amyotrophic lateral sclerosis (ALS). A feedback cycle between nucleocytoplasmic transport (NCT) defect and TDP-43 aggregation was shown to contribute to ...

Virtual reality as a metacognitive training tool for lucid dreaming

Frontiers in Psychology
IntroductionLucid dreaming (LD) involves awareness of being in a dream during REM sleep and depends on the reactivation of metacognitive and reality-monitoring processes.

Affective attention under cognitive load: reduced emotional biases but emergent anxiety-related costs to inhibitory control [PDF]

, 2013
Trait anxiety is associated with deficits in attentional control, particularly in the ability to inhibit prepotent responses. Here, we investigated this effect while varying the level of cognitive load in a modified antisaccade task that employed ...

Which Stimuli Can Trigger Control Adaptation? [PDF]

, 2023
openThe Conflict Monitoring Theory suggests that when conflict trials are detected, an aversive (negative) signal is generated and cognitive control is heightened, resulting in improved performance in subsequent trials.

Temporal dynamics of rumination in daily life: a multi-method investigation of attentional control and metacognitive pathways toward depression

Frontiers in Psychiatry
BackgroundRumination is a central mechanism in depression maintenance. A substantial body of research indicates that deficits in attentional control and positive metacognitive beliefs jointly contribute to this depressive rumination.

Cognitive Control in Young and Older Adults: Does Mood Matter?

, 2021
The dual mechanisms of control framework (DMC) proposes two modes of cognitive control: proactive and reactive control. In anticipation of an interference event, young adults primarily use a more proactive control mode, whereas older adults tend to use a

De novo virulence feature discovery and risk assessment in Klebsiella pneumoniae based on microbial genome vectorization

Communications Biology
Bacterial pathogenicity has traditionally focused on gene-level content with experimentally confirmed functional properties. Hence, significant inferences are made based on similarity to known pathotypes and DNA-based genomic subtyping for risk.
