Background: Instructional videos are commonly employed in physical education (PE) to boost motor skills and motivation. However, their transient nature often hampers their effectiveness. Purpose: This study delves into how video modality and user control affect learning basketball tactics. Study Sample: Eighty third-year students ( M age = 16.13 ye...
Background
Improving the acquisition of complex tactical knowledge through video presentations has attracted considerable attention. Previous research has aimed to facilitate learning by structuring videos including pointing gestures and guided gaze. However, it is debatable whether these cues actually contribute to improved performance in the cont...
Coaches often use pointing gestures alongside their speech to reinforce their message and emphasize important concepts during instructional communications, but the impact of simultaneous pointing gestures and speech on learners’ recall remains unclear. We used eye-tracking and recalled performance to investigate the impact of a coach’s variously ti...
The imagination effect occurs when participants learn better from imagining procedures or concepts rather than from studying them. The aim of the present study was to examine the effects of imagination and level of expertise on memorization of a tactical basketball system. Thirty-six expert and thirty-six novice learners were asked to imagine the f...
This study examines the impact of redundancy and rhythm control in video on the development of tactical knowledge in basketball among 15-16-year-old learners. Participants were exposed to four conditions: "Audio without control" format (N = 20), redundant "Audio + Text without control" format (N = 20), "Audio with control" format (N = 20), and redu...
Numerous studies have been conducted to examine the effects of an instructor's pointing gestures on learning performance across a wide range of academic domains. There are, however, few clear instructional guidelines for enhancing learning from this visual guidance. This study tested the combined effects of the coach's pointing gesture and gaze gui...
The imagination effect occurs when learners who imagine a procedure perform better on a subsequent test than learners who study it. The present study explored whether this effect is restricted to short-term learning or whether it also applies when learning is tested after a delay. Forty novices and forty experts learned about a basketball game syst...
Imagination-to-learn is a specific learning strategy that has been studied in many academic fields. The present study investigated whether imagination is beneficial overall for learning compared to conventional study strategies, while also identifying moderator factors affecting the global effect. A meta-analysis was conducted by scientifically rig...
Even though coach behavior is known to affect learning, it is unclear which specific nonverbal behavior might optimize the teaching of a tactical content in basketball. Using eye-tracking technology, recall construction paradigm, and subjective ratings of mental effort, the present study investigated the question of whether the coach’s eye gaze wou...
Background
Instructional videos are increasingly employed in a physical education domain in order to enhance motor learning and self-motivational beliefs. However, evidence showed that videos are generally ineffective because they often create extraneous loads due to the information transience and passive processing of information.
Purpose
The cur...
Coach’s speech and pointing gestures are closely related. However, the question of whether the coach’s pointing gestures influence the learning of complex game systems is still unclear. The present study examined the moderating roles of content complexity and expertise level on recall performance, visual attention, and mental effort through the coa...
Objectives
This study aimed to investigate the effects of Ramadan diurnal intermittent fasting (RDIF) on cognitive performance, sleep quality, daytime sleepiness, and insomnia in physically active and sedentary elderly individuals.
Methods
A total of 58 participants (62.93 ± 3.99 years) were assigned to one of the following two groups: a sedentary...
The question of how information of play should be presented so that tactical memorisation is optimised is still under discussion. To explore how players’ visual attentional resources are allocated when learning from a game system in basketball, eye movements were registered in the absence and presence of coaches’ pointing gestures. Expert (N = 48)...

The aim of the present study is to evaluate the effect of Ramadan observance (RAM) on decision-making in Kung-Fu athletes. Fourteen male Kung-Fu athletes (mean age = 19 ± 3 years) completed two test sessions: before Ramadan (BR) and at the end of Ramadan (ER). In the afternoon of each session (between 16:00 h and 18:00 h), participants completed: E...
Previous studies with adult human participants revealed mixed effects regarding the relation between spatial ability and visual instructions. In this study, we investigated this question in primary young children, and particularly we explored how young children with varying levels of spatial abilities integrate information from both static and dyna...

Seventy-eight male amateur team sport referees (age: 31.1 ± 10.8 years) participated in this study. Participants responded to the Arabic version of the Pittsburgh Sleep Quality Index (PSQI) and the Epworth sleep...
Background:
The COVID-19 lockdown could engender disruption to lifestyle behaviors, thus impairing mental wellbeing in the general population. This study investigated whether sociodemographic variables, changes in physical activity, and sleep quality from pre- to during lockdown were predictors of change in mental wellbeing in quarantined older ad...
Symptoms of psychological distress and disorder have been widely reported in people under quarantine during the COVID-19 pandemic; in addition to severe disruption of peoples' daily activity and sleep patterns.

Various studies demonstrated that multimedia learning improves when text and pictures are presented contiguously in time rather than separately – the temporal contiguity effect. The present study investigated whether this advantage is restricted to only novice learners (novices) or also extends to more knowledgeable learners (expert), and whether i...

What is already known about this topic? Dynamic visualizations are ubiquitous tools to communicate temporal information.
Evidence has showed that the effects of dynamic visualizations on learning compared with static visualizations have yielded mixed results.
Dynamic visualizations may be particularly apt in teaching about motor ski...
Comprehension of a narrated diagram entail complex cognitive processing as learner is challenged to extract the orally evoked information. The present experiment examined the effects of 2 different forms of attention guidance - bottom-up and top-down - on comprehension performance, cognitive load investment, and motivation to learn, using a 2 × 2 m...
This study investigated the effects of experience and presentation format on memorization processes in 24 experienced and 24 beginner soccer players, using a 2 × 3 factorial design 'Expertise' (Beginner vs. Experienced player) and 'Presentation Format' (Static, Dynamic, Combined). Factors were tested at 3 moments (immediate test, study phase and de...
The recent advances in software and computer technology have enabled the incorporation of dynamic representations into a multitude of educational and training environments. Cognitive load theory has been extensively used to enhance learning from complex dynamic representations by providing appropriate instructional designs to manage learner cogniti...
Objectives: What type of visual presentation is best in helping learners to understand the functioning of a dynamic system and under what conditions? This study investigated the effect of content complexity on perceived cognitive load and performance resulting from studying depicted movements of team play either in an explicit manner (animation) or...
How instructional animations should be designed in order to enhance learning? What factors need to be taken into account in the design of animations? Recent advances in computer-based instruction have made it possible to produce dynamic visualizations such as animations to depict dynamic information that change over time and space. However, there h...
In a 2 × 3 design, we investigated how level of expertise and type of visual presentation
