This study investigates whether the centro-parietal positivity (CPP) reflects evidence accumulation or subjective confidence during perceptual decision-making, finding that CPP is an evidence accumulation signal, not confidence.

The paper identifies robust low-dimensional neural latent representations of implicit perceptual decision confidence using brain-wide iEEG data without explicit confidence reports.

This study finds no group differences in sustained attention performance or wake slow wave activity between ADHD and neurotypical adults, but identifies neural differences suggesting compensatory mechanisms in ADHD.

The paper finds that critical flicker fusion thresholds predict attentional blink magnitude but not global motion sensitivity in non-clinical samples.

The paper identifies a neural signature of urgency in human perceptual decision making that operates independently of movement, using ERP data from three experiments.

This study shows that sleep-like slow waves in wakefulness correlate with perceptual decision-making deficits in stroke patients, indicating network destabilization beyond the lesion site.

This study uses EEG to investigate covert habit activation and control in humans, finding that the lateralized readiness potential tracks habitual responses and frontal midline theta power scales with habit override.

The paper investigates sequential sampling and integration in perceptual decisions using neural data and models, finding that while accuracy improves with evidence duration, neither integration nor a decision bound can be definitively confirmed.

The paper develops a model showing that choice and confidence reports share a single evidence accumulation process with separate boundaries.

The paper investigates how neural systems integrate intermittent perceptual evidence during decision-making, finding distinct patterns of evidence accumulation at different processing levels.

This study uses EEG to analyze perceptual decision-making in ADHD, finding altered neural dynamics in attentional selection, sensory evidence accumulation, and response preparation compared to typically developing children.

The paper uses EEG and fMRI to identify the left intraparietal sulcus as a key region for sensory evidence accumulation during perceptual decision-making.

The paper critiques Frömer et al's analysis of perceptual choice data, arguing their deconvolution method is not suitable for testing bounded accumulation signals.

The paper uses intracranial EEG to identify motor-independent evidence accumulation dynamics in multiple human brain regions during perceptual decision tasks.

The paper examines EEG dynamics during a time interval reproduction task, finding that mu/beta signals and CNV correlate with timing adjustments, while CPP does not.

This study identifies neurophysiological mechanisms causing slowed contralesional response times after stroke by analyzing EEG data from stroke patients and healthy controls.

The paper shows that probabilistic cues bias both motor preparation and sensory evidence encoding during a contrast discrimination task, with sensory effects emerging after extended task exposure.

The paper investigates how decision bounds adjust in intermittent target detection tasks and finds that a model incorporating sensory-level criteria better explains both behavior and neural dynamics.

The paper investigates how evidence accumulation rate influences age-related response speed declines in older adults exposed to enriched environments.

The paper examines how pre- and post-choice neural signals relate to confidence in perceptual decisions, finding that post-choice evidence accumulation continues and is influenced by confidence levels.

The paper investigates how value biases influence fast-paced perceptual decisions through distinct phases of anticipation, detection, and discrimination.

This study investigates how pharmacological manipulations of arousal and sleep-like slow waves affect sustained attention in humans.

This study links model-based learning deficits in compulsivity to impaired task structure representations, showing weaker action-outcome associations and reduced cognitive control in high-compulsivity individuals.

The paper constructs a neurally-informed model of decision-making that incorporates prior knowledge of time constraints and stimulus probability, revealing adjustments in neural processes not captured by standard diffusion models.

The paper shows that subjects begin accumulating evidence before informative stimuli appear, adjusting onset timing based on previous trial foreperiods to handle temporal uncertainty.

The paper examines Contralateral Delay Activity (CDA) as a marker for Mild Cognitive Impairment risk in older adults, finding no group differences in CDA amplitudes despite behavioral performance differences.

This study investigates how catecholamine modulation affects perceptual decision-making using EEG, finding that MPH and ATM shorten reaction times and alter P3b latency.

This study examines how pupil-linked arousal modulates neural and behavioural signatures of perceptual evidence accumulation during decision-making.

This study compares age-related changes in neural and computational models of decision making, finding discrepancies and using neural data to refine the model.

The paper investigates how urgency signals in decision-making affect neural and motor responses across different processing levels.
