The things you do: Implicit person models guide online action observation.
… research favoured bottom-up views where observed actions are matched to higher level (or motor) representations, recent accounts suggest top-down processes where prior knowledge guides perception of others’ actions, in a predictive manner. This thesis investigated how person-specific models of …

The Role of Action Observation in Motor Memory Formation and Retention across Multiple Days
<p>Action observation has promise to expand therapy options in physical therapy to promote motor rehabilitation and recovery. Previous observation studies have found that action observation can facilitate motor learning: people are able to pick up context-specific cues from others’ movements to …

The Use of Action Observation and Imitation in the Treatment of Upper Limb Paresis Early After Stroke
… Aim: To ascertain if a new therapy called “Observation with intent To Imitate” (OTI)+Motor Practice (MP) sufficiently enhanced UL recovery in individuals with moderate/severe paresis early after stroke to justify proceeding to subsequent dose finding (phase I) and efficacy (phase II) trials. …

Observation inflation and self-action inflation. Investigation of source memory errors as a result of action observation and action performance
… thesis investigates two source memory errors: observation inflation, where observed actions are misremembered as being performed; and self-action inflation in which self-performed actions are misremembered as having been performed by somebody else. It has been proposed that these inflations …

Transcranial alternating current stimulation to areas associated with the human mirror neuron system reveals modulation to mu-suppression and corresponding behaviour
… by neuronal activity that responds to both action observation and execution of the same movement. This activity has been directly observed in both macaque monkeys and in humans. There is an abundance of studies using indirect measures of neuronal activity to indicate hMNS-related activity …

EXPLORING COVERT MOTOR PROCESSES: BEHAVIORAL INSIGHTS AND INNOVATIVE APPLICATIONS OF TRANSCRANIAL MAGNETIC STIMULATION
… on motor imagery, motor preparation, and action observation. Traditional methods have primarily relied on the 1 muscle × 1 action (1m1a) approach, in which transcranial magnetic stimulation (TMS) is applied to the motor cortex and motor-evoked potentials (MEPs) are recorded from a single …

Neurobehavioural representations of observed action viewpoint
… examined whether the viewpoint from which an action was observed could modulate the behavioural and neural activity of the observer. Chapter 2 presents motion capture data from a manual prehension task which manipulated observed reach height. Actions were observed from two allocentric …

Imitation of atypical biological motion in autism spectrum disorders
… provided, although eye movements recorded during action- observation was similar to controls, imitation of atypical biological motion was still impaired. In Chapter Four across three experiments it was shown that adults with autism exhibit reasonably high-fidelity imitation of atypical biological …

Effects of sensorimotor learning on the human mirror neuron system
… in response both to the performance and to the observation of specific actions, has prompted extensive research into their properties, and into the possible functions of a putative mirror neuron system in humans. Little is known, however, about how such neurons acquire their matching properties. …

Source memory for actions
… source memory for performed and observed actions in recall and recognition tasks. The motor simulation account predicts that motor activation during action observation results in source misattributions of observed actions as self-performed. Alternatively, source judgements at test may be …

Experience Dependent Sensorimotor Functioning in Adults with Severe Autism Spectrum Disorder
… Three) was used to verify an intact perception-action link. In Chapter Four, in Twists, the trampolining group (those with sensorimotor experience) had a First Fixation Location on the incongruent model on the first trial but had a longer First Fixation Duration on the congruent model across the …

Shaping the perceptual representation of observed human action through prediction.
Understanding the actions of others is crucial for all social interactions. Despite a dynamic and complicated social world, humans can derive the goals, attitudes and beliefs that drive others’ actions, imbuing them with meaning and understanding. While such abilities were traditionally accounted …

Sensorimotor experience in virtual environments
… mapped neural correlates of human interactions with complex virtual reality hands avatars moving synchronously with the subject's own hands, Findings indicate that healthy control subjects learned intransitive gestures in virtual environments using the first and third person avatars, …

Characterizing the spatiotemporal profile and the level of abstractness of action representations: neural decoding of magnetoencephalography (MEG) and functional magnetic resonance imaging (fMRI) data
When we observe other people's actions, a network of temporal, parietal and frontal regions is recruited, known as action observation network (AON). This network includes areas that have been reported to be involved when we perform actions ourselves. Such findings support the view that action …

The Contribution of Planning-related Motor Processes to Mental Practice and Imitation Learning
… question. It utilizes a framework of ideomotor action planning theories, and tests whether mental practice may specifically draw upon planning- rather than execution-related motor processes, specifically those processes that “bind” intended action features to action plans. Experiments 1 to 4 …

Decoding Minds: Mentalistic Inference in Autism Spectrum Disorders and ChatGPT Models
… from behaviour, is a key element of social interactions, especially when challenges arise. Just by observing an action or listening to a verbal description of it, adults and infants are able to make robust and rapid inferences about an agent’s intentions, desires, and beliefs. This thesis …

A NIRS Study of Violinists and Pianists Employing Motor and Music Imageries to Assess Neural Differences in Music Perception
<p>Do musicians imagine movements differently? Are instrument-specific movements represented differently in the brain? The current study explores the perceptual differences in imagining music and movements. While attached to a near infrared spectroscopy (NIRS) device, violinists and pianists of …
