Mutual gaze and movement synchrony boost observers' enjoyment and perception of togetherness when watching dance duets.

As social beings, we are adept at coordinating our body movements and gaze with others. Often, when coordinating with another person, we orient ourselves to face them, as mutual gaze provides valuable cues pertaining to attention and intentions. Moreover, movement synchrony and mutual gaze are associated with prosocial outcomes, yet the perceptual consequences of these forms of coordination remain poorly understood.

Face naming and recollection represent key memory deficits in developmental prosopagnosia.

Previous studies have found that face perception deficits do not fully account for the severity of face recognition deficits in developmental prosopagnosia (DP). Researchers have begun identifying deficient memory mechanisms such as impaired face recollection, but these findings require replication, and further characterization of additional memory deficits is necessary. Our goals were to replicate prior findings of face recollection impairment in DP and extend these findings to assess different types of face associative memory.

Social Interaction Anxiety in Developmental Prosopagnosia: Prevalence, Severity, and Individual Differences.

Objective: Although elevated social anxiety in developmental prosopagnosia (DP) has been reported in anecdotal and qualitative studies, the current study sought to better quantify the prevalence, severity, and moderators of social anxiety in a large DP sample.

Method: A total of 88 DPs and 58 controls completed the validated Social Interaction Anxiety Scale and assessments of face recognition, autism traits, personality (Big Five Inventory), and coping strategies.

Results: DPs reported greater social anxiety symptoms (M = 30.

Fox Insight at 5 years - a cohort of 54,000 participants contributing longitudinal patient-reported outcome, genetic, and microbiome data relating to Parkinson's disease.

Fox Insight is an online, longitudinal study of over 54,000 people with and without Parkinson's disease, facilitating discovery, validation, and reproducibility in Parkinson's disease research. The study administers routine longitudinal assessments, one-time questionnaires on an array of topics such as environmental exposure or COVID-19, plus genetic and microbiome data collection. Researchers can explore and download patient-reported outcomes data and Parkinson's disease related genetic variants upon completing a Data Use Agreement.

A machine learning contest enhances automated freezing of gait detection and reveals time-of-day effects.

Freezing of gait (FOG) is a debilitating problem that markedly impairs the mobility and independence of 38-65% of people with Parkinson's disease. During a FOG episode, patients report that their feet are suddenly and inexplicably "glued" to the floor. The lack of a widely applicable, objective FOG detection method obstructs research and treatment.
