Evidence of Implicit and Explicit Motor Learning during Gait Training with Distorted Rhythmic Auditory Cues
J Mot Behav. 2023 Jul 2:1-10. doi: 10.1080/00222895.2023.2231874. Online ahead of print.ABSTRACTGait training with rhythmic auditory cues contains motor learning mechanisms that are weighted more explicitly than implicitly. However, various clinical populations may benefit from a shift to gait training with greater implicit motor learning mechanisms. To investigate the ability to incorporate more implicit-weighted motor learning processes during rhythmic auditory cueing, we attempted to induce error-based recalibration using a subtly varying metronome cue for naïve unimpaired young adults. We assessed the extent of implic...

The Strategy of Human Movement Control and Teaching Motor Skills in Norm and Pathology
J Mot Behav. 2023 Jul 2:1-5. doi: 10.1080/00222895.2023.2229769. Online ahead of print.ABSTRACTThe strategy used by the brain to organize human goal-directed movements is still debated. Here, I argue that without the knowledge of this strategy, teaching movement skills required in complex sports activities and for rehabilitation of motor disorders remains an art and can often result in inefficient techniques and misleading instructions. However, the leading joint hypothesis offers a solution to this problem. It suggests that the control strategy consists in rotation of a single ('leading') joint actively and using the biom...

A Violation of Fitts' Law is Maintained in Ecologically Valid Settings
J Mot Behav. 2023 Jul 2:1-13. doi: 10.1080/00222895.2023.2210530. Online ahead of print.ABSTRACTA 'violation' of Fitts' Law, or Fitts' Equation, occurs when each potential target location is outlined before and during a reaching movement. Past studies have measured the violation in highly controlled laboratory environments, limiting the generalizability of findings. The purpose of the study was to replicate the violation of Fitts' Equation in the homes of participants using a novel portable apparatus during the COVID-19 pandemic. Movements were measured independently with an accelerometer and touch screen, which allowed fo...

Gaze Control and Tactical Decision-Making Under Stress in Active-Duty Police Officers During a Live Use-of-Force Response
J Mot Behav. 2023 Jun 29:1-12. doi: 10.1080/00222895.2023.2229946. Online ahead of print.ABSTRACTPolice officers during dynamic and stressful encounters are required to make rapid decisions that rely on effective decision-making, experience, and intuition. Tactical decision-making is influenced by the officer's capability to recognize critical visual information and estimation of threat. The purpose of the current study is to investigate how visual search patterns using cluster analysis and factors that differentiate expertise (e.g., years of service, tactical training, related experiences) influence tactical decision-maki...

The Role of the Corpus Callosum (Micro)Structure in Bimanual Coordination: A Literature Review Update
J Mot Behav. 2023 Jun 19:1-13. doi: 10.1080/00222895.2023.2221985. Online ahead of print.ABSTRACTThe characterization of callosal white matter is crucial for understanding the relationship between brain structure and bimanual motor function. An earlier literature review established this. With advancements in neuroimaging and data modeling, we aim to provide an update on the existing literature. Firstly, we highlight new CC parcellation approaches, such as functional MRI- and atlas-informed tractography and in vivo histology. Secondly, we elaborate on recent insights into the CC's role in bimanual coordination, drawing evid...
