Prior Information Shapes Perceptual Evidence Accumulation Dynamics Differentially in Psychosis

This study examines how prior information affects perceptual decision-making in psychosis, finding that individuals with psychosis show reduced sensory gain and increased pre-evidence biases compared to healthy controls.

Circadian fluctuations in glucocorticoid level predict perceptual discrimination sensitivity

The paper shows that higher cortisol levels before a hearing test improve pitch discrimination in humans across different ages.

The vulnerability of working memory to distraction is rhythmic

This study shows that working memory vulnerability to distraction follows a rhythmic pattern, with 2.5-Hz cycles affecting both neural and behavioral measures of distraction.

Aberrant perceptual judgements on speech-relevant acoustic features in hallucination-prone individuals

The paper investigates how hallucination-prone individuals perceive speech-like acoustic features, finding they down-weight speech-typical low frequencies and prioritize high frequencies, with confidence influenced by hallucination proneness and schizotypy.

Working-memory disruption by task-irrelevant talkersdepends on degree of talker familiarity

This study shows that familiar distracting talkers impair working memory for spoken digits more than unfamiliar ones, but only in students, not in family members and friends.

Perceptual grouping in the cocktail party: contributions of voice-feature continuity

The paper investigates how voice features like glottal-pulse rate and vocal-tract length contribute to the voice-continuity benefit in the cocktail party problem.
