“…Such paradigms, therefore, differed from many real-life situations and were criticized as lacking ecological validity [46][47][48][49]. It has been documented that the outcome of typical laboratory paradigms may not be transferable to many everyday-life situations [46, 50,51]. The present study, therefore, used a more realistic cognitive-motor multitasking scenario, i.e., street crossing, implemented in virtual reality, as already described in [52], and similar as in [53]- [55]].…”

Here, we investigated whether age-related cognitive-motor interference is influenced by individual’s levels of executive functions and physical fitness in a more ecological valid scenario. Participants (N = 61, 65–75 years) crossed a virtual street on a treadmill without getting hit by a car during single- and multitasking (typing numbers). Outcomes were cognitive and motor performance parameters. Further, participants’ executive functions, motor coordinative, and cardiovascular fitness were tested. Linear mixed-effects models showed beneficial main effects of executive functions for the cognitive parameters typing (p = .004) and crossing failures (p = .023), and a beneficial main effect of motor coordinative fitness for the motor parameter stay time (p = .043). We found interaction effects between condition and executive functions for typing (p = .044) with higher benefits during multi- than single-tasking. Commonality analysis revealed an increasing relative contribution of executive functions on cognitive parameters and of motor coordinative fitness on motor parameters from single- to multitasking. Additionally, the proportion of variance commonly explained by executive functions and physical fitness was small for both cognitive and motor parameters. Findings substantiate the benefits of maintaining cognitive functioning and physical fitness up to old age.

“…walking, reaching and grasping) miss out the medley of factors that have real implications and influence movement in everyday life but are difficult to recreate outside the real situations in which they occur. For example, walking could be in the context of walking in a busy train station and anxious to catch one's train, and reaching and grasping could be in the context of deliberating on the price and expiry date on several items during grocery shopping before choosing one [53]. More naturalistic movements in real activities (e.g.…”

Movement dataset reviews exist but are limited in coverage, both in terms of size and research discipline. While topic-specific reviews clearly have their merit, it is critical to have a comprehensive overview based on a systematic survey across disciplines. This enables higher visibility of datasets available to the research communities and can foster interdisciplinary collaborations. We present a catalogue of 704 open datasets described by 10 variables that can be valuable to researchers searching for secondary data: name and reference, creation purpose, data type, annotations, source, population groups, ordinal size of people captured simultaneously, URL, motion capture sensor, and funders. The catalogue is available in the supplementary materials. We provide an analysis of the datasets and further review them under the themes of human diversity, ecological validity, and data recorded. The resulting 12-dimension framework can guide researchers in planning the creation of open movement datasets. This work has been the interdisciplinary effort of researchers across affective computing, clinical psychology, disability innovation, ethnomusicology, human-computer interaction, machine learning, music cognition, music computing, and movement neuroscience.

“…Indeed, previous research has documented that behavioral context is a powerful modifier of various cognitive and motor skills. This has been shown by comparing locomotion in the laboratory versus in a community park (Bock & Beurskens, 2010 ), manual grasping as an isolated act versus as part of a computer game (Bock & Züll, 2013 ) or as part of grocery shopping (Kim & Bock, 2019 ), and decision making, concentration (Moskaliuk et al, 2017 ), perceptual speed, episodic memory, working memory, spatial skills and reasoning (Verhaeghen et al, 2012 ) in standardized tests versus in the workplace. Given this evidence, it appears likely that behavioral context would modify sequence learning as well.…”

The role of environmental contextual cues in sequence learning: evidence from a virtual maze context

Studies on sequence learning usually focus on single, isolated stimuli that are presented sequentially. For example, in the serial reaction time (RT) task, stimuli are either presented in a predictable sequence or in a random sequence, and better performance with the predictable sequence is taken as evidence for sequence-specific learning. Yet, little is known about the role of environmental context cues in sequence learning. If the target stimuli are embedded in a meaningful context, would this facilitate learning by providing helpful contextual associations or would it hinder learning by adding distracting stimuli? This question was examined in two studies. A pilot study compared sequence learning in a virtual maze with a horizontal vs. vertical maze context, in which arrow stimuli guide spatial lever movement responses that resulted in a corresponding virtual transport on the screen. The results showed only overall somewhat better performance with the vertical maze compared to the horizontal maze, but general practice effects and sequence-specific learning effects were the same for both contexts. The main study compared sequence learning with a maze context to sequence learning of arrows without a maze context. The results showed significantly better learning with maze context than without context. These data suggest that the maze context facilitated sequence learning by inducing a meaningful spatial representation (“mental map”) similar to that formed in wayfinding.
