Genetic variation influences food-sharing sociability in honey bees Open
Individual variation in sociability is a central feature of every society. This includes honey bees, with some individuals well connected and sociable, and others at the periphery of their colony’s social network. However, the genetic and …

High rates of Parkinson’s disease diagnosis in the autistic population: True co-occurrence or a product of overlapping traits? Open
Older autistic adult literature is sparse, and little is known about the aging autistic population. However, recent evidence suggests an increased prevalence of Parkinson's disease (PD) diagnosis in the autistic population. It may initiall…

Are Keynote and Invited Speakers at State Behavior Analytic Conferences Experts on Their Presentation Topics? Open
Board Certified Behavior Analysts® (BCBA®s) must acquire 32 continuing education units (CEUs) every two years. One way BCBAs obtain CEUs is by attending their state chapter conferences, which feature keynote speakers and invited speakers w…

Biological kinematics: a detailed review of the velocity-curvature power law calculation Open
Bodily movements exhibit kinematic invariances, with the “one-third power law” relating velocity to curvature amongst the most established. Despite being heralded amongst the “kinematic laws of nature” (Flash 2021, p. 4), there is no conse…

Facial movements as behavioural markers for autism: A Bayesian prevalence and machine-learning proof-of-concept study Open
Autism research has long sought reliable behavioural markers to support early identification and diagnosis. In recent years, researchers have increasingly recognised the potential of facial movements as behavioural markers for autism. To m…

The Fitness, Rest, and Exercise for Strength and Health (FRESH) Study: A Three-Year Comparison of College Students’ Perceived and Measured Health Metrics Open
The undergraduate college years are a critical transition period for young adults in establishing life-long health behaviors. Background/Objective: Within the FRESH Study, we aimed to understand the relationship between perceived physical …

A cross-cultural examination of bi-directional mentalising in autistic and non-autistic adults Open
So-called ‘mismatch accounts’ propose that, rather than arising from a socio-cognitive deficit present in autistic people, mentalising difficulties are the product of a mismatch in neurotype between interaction partners. Although this idea…

Methylphenidate enhances or impairs the cognitive control of Pavlovian bias depending on working memory capacity Open
Value-based decision-making is regulated by a delicate interplay of instrumental and Pavlovian controllers. Here we assessed the role of catecholamines in this interplay. We investigated the effects of the catecholamine reuptake inhibitor …

Spatiotemporal structure and substates underly emotional signalling in facial expressions and speech movements Open
From overt emotional displays to a subtle eyebrow raise during speech, facial expressions are key cues for social interaction. How these inherently dynamic signals encode emotion remains only partially understood. Moreover, despite the ubi…

Dopaminergic manipulations affect the modulation and meta-modulation of movement speed: Evidence from two pharmacological interventions Open
A body of research implicates dopamine in the average speed of simple movements. However, naturalistic movements span a range of different shaped trajectories and rarely proceed at a single constant speed. Instead, speed is reduced when dr…

Disruption of dopamine D2/D3 system function impairs the human ability to understand the mental states of other people Open
Difficulties in reasoning about others’ mental states (i.e., mentalising/Theory of Mind) are highly prevalent among disorders featuring dopamine dysfunctions (e.g., Parkinson’s disease) and significantly affect individuals’ quality of life…

Cross-cultural variation in experiences of acceptance, camouflaging and mental health difficulties in autism: A registered report Open
Recent findings suggest that stigma and camouflaging contribute to mental health difficulties for autistic individuals, however, this evidence is largely based on UK samples. While studies have shown cross-cultural differences in levels of…

The inside out model of emotion recognition: how the shape of one’s internal emotional landscape influences the recognition of others’ emotions Open
Some people are exceptional at reading emotional expressions, while others struggle. Here we ask whether the way we experience emotion “on the inside” influences the way we expect emotions to be expressed in the “outside world” and subsequ…

Mismatching expressions: Spatiotemporal and kinematic differences in autistic and non-autistic facial expressions Open
Preliminary studies are suggestive of differences in facial expressions between autistic and non-autistic individuals. However, it is unclear what specifically is different, whether such differences remain after controlling for facial morp…

The conceptualisation, experience, and recognition of emotion in autism: Differences in the psychological mechanisms involved in autistic and non-autistic emotion recognition Open
Existing literature suggests that differences between autistic and non-autistic people in emotion recognition might be related to differences in how these groups experience emotions themselves. Specifically, autistic individuals may show d…

Autistic adults exhibit highly precise representations of others’ emotions but a reduced influence of emotion representations on emotion recognition accuracy Open
Background: “Visual representations of emotions” - the way you picture expressions in your “minds’ eye” - are important contributors to emotion recognition. For example, people who have precise representations, that are clearly differentia…

Exploring facial expression recognition in Parkinson’s Open
Parkinson’s is a neurodegenerative condition and some studies have suggested that people with Parkinson’s (PwP) experience difficulties with recognising facial expressions. Previous studies, however, have focussed on static stimuli, as opp…
