Introduction
In my research, I mainly focus on two different research areas: motor decision making and joint action. Research in both fields is grounded on the concept of embodiment and targets the question of how movements are coordinated to account for the dynamics and uncertainties in the environment. Further, I am investigating how movement coordination is affected by the interplay of age-related changes in underlying cognitive and motor processes.

When acting jointly, individuals often attend and respond to the same object or spatial location in complementary ways (e.g., when passing a mug, one person grasps its handle with a precision grip; the other receives it with a whole-hand grip). At the same time, the spatial relation between individuals’ actions affects attentional orienting: one is...

Embodiment research is at a turning point. There is an increasing amount of data and studies investigating embodiment phenomena and their role in mental processing and functions from across a wide range of disciplines and theoretical schools within the life sciences. However, the integration of behavioral data with data from different biological le...

Anodal transcranial direct current stimulation (tDCS) may assist in counteracting age-related decline in cognitive and motor functions. The current study investigated the potential impact of anodal tDCS, and the timing of its application, in mitigating age-related deficits in motor sequence learning. Forty-eight healthy older adults received, over...

Background Community-dwelling older people are frequently affected by vertigo, dizziness and balance disorders (VDB). We previously developed a care pathway (CPW) to improve their mobility and participation by offering standardized approaches for general practitioners (GPs) and physical therapists (PTs). We aimed to assess the feasibility of the in...

The processes underlying motor decision-making have recently caught considerable amount of scientific attention, focusing on the integration of empirical evidence from sensorimotor control research with psychological theories and computational models on decision-making. Empirical studies on motor decision-making suggest that the kinematics of goal-...

In recent years, theory-building in motor neuroscience and our understanding of the synergistic control of the redundant human motor system has significantly profited from the emergence of a range of different mathematical approaches to analyze the structure of movement variability. Approaches such as the Uncontrolled Manifold method or the Noise-T...

Objectives: The aim of this study was to investigate how age-related performance differences in a visuospatial sequence learning task relate to age-related declines in cognitive functioning. Method: Cognitive functioning of 18 younger and 18 older participants was assessed using a standardized test battery. Participants then undertook a perceptual...

Aims: The human motor system has the incredible capability to adapt to a constantly changing environment by flexibly adjusting movement coordination at the effector level to gain stability at the task level, i.e. the movement outcome. The present study investigated how the cognitive load of a motor task influences movement coordination, particularl...

Aims: Aging is associated with performance decrements in visual-spatial learning, whereby significant inter-individual variability is observed. The influencing factors differentiating better and worse performing younger and older people still need to be identified. The aim of this study was to investigate the interaction of aging and cognition on t...

In everyday situations, pedestrians deploy successful strategies to avoid collisions with other persons crossing their paths. In this study, 2 experiments were conducted to investigate to what extent personal or situational characteristics affect role attribution and contribution to successful collision avoidance in human locomotion. Pairs of subje...

When walking in open space, collision avoidance with other pedestrians is a process that successfully takes place many times. To pass another pedestrian (an interferer) walking direction, walking speed or both can be adjusted. Currently, the literature is not yet conclusive of how humans adjust these two parameters in the presence of an interferer....
Article

Empirical evidence suggests that the ability to stabilize important task variables of everyday movements by synergistically coordinating redundant degrees of freedom decreases with aging. The aim of the current study was to investigate whether this decrease may be regarded as a characteristic that also applies for the control of multiple task varia...

Ziel der vorliegenden Studie war es, den Einfluss spezifischer visueller Wahrnehmungseffekte auf die Handlungskontrolle von closed-loop-kontrollierten Zielbewegungen zu untersuchen. Mittels einer simultanen Grosen-Kontrast-Illusion (Ebbinghaus-Titchener-Illusion) wurden die Wahrnehmungseffekte manipuliert. Die Handlung und die inharenten informatio...

Einleitung: Studien an propriozeptiv deafferentierten Patienten haben gezeigt, dass eine beeintrachtigte Propriozeption die Bewegungsausfuhrung negativ beeinflusst. Diese Studien wurden an Patienten durchgefuhrt, deren motorisches Kontrollsystem sich mit der Dauer der Schadigung an das Fehlen der Propriozeption anpassen konnte. Unklar ist jedoch bi...

Reaching movements are often used to study the effectiveness of motor control processes with respect to the final position of arm and hand. Empirical evidence shows that different targets can be grasped with similar final position accuracy. However, movements that achieve similar accuracy at their final position may nevertheless be controlled diffe...
Article
Hikosaka et al. (1999) proposed that sequential movements are acquired in independent visual-spatial and motor coordinate systems with coding initially represented in visual-spatial coordinates, and later after extended practice in motor coordinates. One aspect of sequence learning that has not been systematically studied, however, is the question...
Article
Investigating motor control processes is of primary interest in a number of scientific and practical fields. Movement variability is of increasing interest in this context. However, until now little has been known about the time course of variability during movement execution. The objective of this study was to investigate the influence of visual i...

This experiment investigated differencesin transfer to novel task dynamicsin movement sequence learningand handed- ness. Increased loads were used to determine the transfer profiles of movement sequences to practiced and unpracticed limbs. The task required participants to move a horizontal lever to 16 sequentially projected targets. One group prac...
Article
An experiment was designed to determine if the addition of a load altered the effector transfer profile observed in earlier experiments using multi-element movement sequences. The acquisition task required participants to move a horizontal lever (with 0.567kg load) to 16 sequentially projected targets. One group practiced the movement sequence with...
Article
Previous research suggests that movements are represented early in practice in visual-spatial coordinates/codes, which are effector independent, and later in practice in motor coordinates/codes (e.g., joint angles, activation patterns), which are effector dependent. In the present experiments, the task was to reproduce 1.3 s patterns of elbow flexi...

An interlimb practice paradigm was designed to determine the role that visual-spatial (Cartesian) and motor (joint angles, activation patterns) coordinates play in the coding and learning of complex movement sequences. Participants practised a 16-element movement sequence by moving a lever to sequentially presented targets with one limb on Day 1 an...

Zusammenfassung. Für das Lernen von Bewegungssequenzen wird postuliert, dass die Codierung einer entsprechenden Repräsentation parallel in zwei unterschiedlichen Koordinatensystemen erfolgt, einem visuellen System (visuell-räumlicher Code) und einem motorischen System (motorischer Code). Dabei wird zusätzlich angenommen, dass sich der visuell-räuml...
