The Perceptual Consistency and Association of the LMA Effort Elements

Laban Movement Analysis (LMA) and its Effort element provide a conceptual framework through which we can observe, describe, and interpret the intention of movement. Effort attributes provide a link between how people move and how their movement communicates to others. It is crucial to investigate the perceptual characteristics of Effort to validate whether it can serve as an effective framework to support a wide range of applications in animation and robotics that require a system for creating or perceiving expressive variation in motion. To this end, we first constructed an Effort motion database of short video clips of five different motions: walk, sit down, pass, put, wave performed in eight ways corresponding to the extremes of the Effort elements. We then performed a perceptual evaluation to examine the perceptual consistency and perceived associations among Effort elements: Space (Indirect/Direct), Time (Sustained/Sudden), Weight (Light/Strong), and Flow (Free/Bound) that appeared in the motion stimuli. The results of the perceptual consistency evaluation indicate that although the observers do not perceive the LMA Effort element 100% as intended, true response rates of seven Effort elements are higher than false response rates except for light Effort. The perceptual consistency results showed varying tendencies by motion. The perceptual association between LMA Effort elements showed that a single LMA Effort element tends to co-occur with the elements of other factors, showing significant correlation with one or two factors (e.g., indirect and free, light and free).

Presenting KAPODI – The Searchable Database of Emotional Stimuli Sets

Emotional stimuli such as images, words, or video clips are often used in studies researching emotion. New sets are continuously being published, creating an immense number of available sets and complicating the task for researchers who are looking for suitable stimuli. This paper presents the KAPODI-database of emotional stimuli sets that are freely available or available upon request. Over 45 aspects including over 25 key set characteristics have been extracted and listed for each set. The database facilitates finding of and comparison between individual sets. It currently contains sets published between 1963 and 2020. A searchable online version ( https://airtable.com/shrnVoUZrwu6riP9b ) allows users to select specific set characteristics and to find matching sets accordingly, as well as to add new published sets.

Multi-inquiry hybrid e-learning: Instructor-learner experiences

Background: Hybrid teaching methodologies involve the purposeful combination of traditional teaching with technology advances. Despite some challenges, they have gained popularity recently, especially during the coronavirus pandemic. This study evaluated hybrid e-learning with multiple inquiries involving students’ receptiveness, preferences, behaviours and instructor observations. Method: The methodology involved a mixed-method approach with a qualitative observational case study, surveys and interviews for problem-based learning alternatives to traditional lectures. Instruction included: 1) Assigned primary literature reading with study questions to be completed before class; 2) Out-of-class online video-clips with visual, practical application (i.e. lithium and non-lithium induced tremor assessment) and online discussion in CANVAS Learning Management System; 3) Start-of-class quiz in ExamSoft, in-class team-based application questions with instructor-led discussion; 4) Out-of-class team final exam review assignment in CANVAS. Results: Qualitative themes were student engagement, flexibility, preferences, academic and non-academic stressors, etiquette, and defining responsibility for academic success. The majority of students preferred primary literature review, video clips, followed by online CANVAS discussions. Written assignments were the least desirable. Conclusion: These experiences are useful for qualitative evaluation of teaching and learning methods.

If You Are Old, Videos Look Slow. The Paradoxical Effect of Age-Related Motor Decline on the Kinematic Interpretation of Visual Scenes

Perception and action are tightly coupled. However, there is still little recognition of how individual motor constraints impact perception in everyday life. Here we asked whether and how the motor slowing that accompanies aging influences the sense of visual speed. Ninety-four participants aged between 18 and 90 judged the natural speed of video clips reproducing real human or physical motion (SoS, Sense-of-Speed adjustment task). They also performed a finger tapping task and a visual search task, which estimated their motor speed and visuospatial attention speed, respectively. Remarkably, aged people judged videos to be too slow (speed underestimation), as compared to younger people: the Point of Subjective Equality (PSE), which estimated the speed bias in the SoS task, was +4% in young adults (<40), +12% in old adults (40–70) and +16% in elders. On average, PSE increased with age at a rate of 0.2% per year, with perceptual precision, adjustment rate, and completion time progressively worsening. Crucially, low motor speed, but not low attentional speed, turned out to be the key predictor of video speed underestimation. These findings suggest the existence of a counterintuitive compensatory coupling between action and perception in judging dynamic scenes, an effect that becomes particularly germane during aging.

Runet Users' Attitude to Outrageous Content in Virtual Social Environments

This study of the Runet virtual social environments deals with identifying and analyzing user reactions to watching a video clip containing outrageous behavior, and studying social attitudes of the respondents. The Celebrium-X platform employing the adjoint ideomotion technology for remote collection and processing of group neuro-responses was chosen as a research tool. As the empirical basis of the research, the raw data obtained as a result of the conducted survey was used. The results of the study have shown the respondents' negative attitude to publishing of outrageous video clips in virtual social environments. The Internet audience realizes a negative effect produced by the aggressive content on people's psychological sphere and social behavior.

Non-Linear Curriculum Experiences for Student Learning and Work Design

Developing curriculum aligned with employment outcomes often includes linear design. However, students do not cognitively approach their education linearly, and economies do not fluctuate linearly. We should support students' natural non-linear approaches to education and employment. Chat bots that include non-linear presentation of text, short video clips, and images can help us design curricular experiences that mirror and personalize unique student cognition. As students navigate nudges of content within a chat bot on their phone or full-page views in an internet browser, the initial content will catalyze new questions and non-linear thinking for students to then explore their own employment related journeys. This will buttress students to be agents in their learning instead of objects of linear design. Machine learning models feeding chat bot learning journeys and experiences can help improve organic assessment for a constellation of employment preparedness outcomes and connection.

Automation in the Intralingual Subtitling Process

The demand for intralingual subtitles for television and video content is increasing. In Finland, major broadcasting companies are required to provide intralingual subtitles for all or a portion of their programming in Finnish and Swedish, excluding certain live events. To meet this need, technology could offer solutions in the form of automatic speech recognition and subtitle generation. Although fully automatic subtitles may not be of sufficient quality to be accepted by the target audience, they can be a useful tool for the subtitler. This article presents research conducted as part of the MeMAD project, where automatically generated subtitles for Finnish were tested in professional workflows with four subtitlers. We discuss observations regarding the effect of automation on productivity based on experiments where participants subtitled short video clips from scratch, by respeaking and by post-editing automatically generated subtitles, as well as the subtitlers’ experience based on feedback collected with questionnaires and interviews. Lay summary This article discusses how technology can help create subtitles for television programmes and videos. Subtitles in the same language as the content help the Deaf and the hard-of-hearing to access television programmes and videos. They are also useful for example for language learning or watching videos in noisy places. Demand for subtitles is growing and many countries also have laws that demand same-language subtitles. For example, major broadcasters in Finland must offer same-language subtitles for some programmes in Finnish and Swedish. However, broadcasters usually have limited time and money for subtitling. One useful tool could be speech recognition technology, which automatically converts speech to text. Subtitles made with speech recognition alone are not good enough yet, and need to be edited. We used speech recognition to automatically produce same-language subtitles in Finnish. Four professional subtitlers edited them to create subtitles for short videos. We measured the time and the number of keystrokes they needed for this task and compared whether this made subtitling faster. We also asked how the participants felt about using automatic subtitles in their work. This study shows that speech recognition can be a useful tool for subtitlers, but the quality and usability of technology are important.

How fishing cats Prionailurus viverrinus Bennett, 1833 fish: describing a felid’s strategy to hunt aquatic prey

The fishing cat’s persistence in a ‘semi-aquatic niche’ suggests the evolution of a successful hunting strategy. We describe it for the first time by analysing 197 camera-trap video-clips, collected from a participatory-science initiative, within an ethogram framework. The cats spent ∼52% of the time sitting and waiting for prey (fishes) to come nearer and took limited attempts to hunt (3.89%) in deeper waters (in which the upper portions of the cat’s body were submerged), where its hunting success was found to be 42.86%. In shallow waters, it adopted a predominantly active mode of hunting (∼96%) to flush out prey.

Towards the Development of the Decolonized Pedagogy for Higher Education in South Africa: A Students’ Perspective

This chapter presents views, opinions, and perceptions about the curriculum theories that propagate educational perspectives of social injustice, cultural exclusion, supremacy, socio-economic inequality, and inequity. The data collection method was question and answer and deductive reasoning conducted in small groups in education studies classes. Pieces of information recorded in video clips during the COVID-19 lockdown were analysed through qualitative procedures, transcribing verbal data, and sorting coded categories of data. First, the frequencies of statements indicating trends in thoughts form themes classified as convergent and divergent perspectives. The interpretation of themes identified during data analysis seeks to address the problem statement in this chapter, which is the paradigm shift for a conceptualised decolonised curriculum in South Africa. Thus, the research question asked in the study is “what principles should underpin pedagogical content knowledge (PCK) of pre-service teacher education and training?” The source of data was interviews and document analysis. The synthesis of the results drawn from the raw data was based on the theoretical and conceptual framework established from the works of scholarship researchers on decolonised education. The interpretation of the findings addressing the problem statement and the research question was presented through convergent and divergent perspectives that characterise the beliefs and thoughts of students about curriculums for decolonised education in South Africa. The study highlights uncertainties about the concepts, divergent conceptual stances on decolonised education, and the lack of uniformity in the perceptions of philosophical principles or foundations of perspectives on decolonised education.

Fidgety Movements Assessment Accuracy Survey in Japan

To investigate the accuracy of fidgety movements (FMs) assessment in Japanese assessors. Sixty specialists participated in the first survey. Of the participants, 18 were assessors certified by the GMs basic-training course. The surveys were composed of FMs assessment of 20 video clips. The correct assessment rates (CARs) were investigated. The survey videos were judged into three types: normal (F + +, F +), abnormal (AF) and absent (F + -, F-). After the first survey, each participant performed a self-learning exercise using clips of the first survey. The follow-up survey was conducted three months after the first survey. The median CAR of the first survey was 65% in certified assessors and 50% in noncertified assessors. The median CARs of certified assessors were significantly higher than that of noncertified assessors for all clips and for normal FMs and AF clips (p < 0.01). After 3 months of self-learning exercise the CARs in each judgement type improved in 28 follow-up survey participants. Their median CAR improved from 60% in the first survey to 84% in the follow-up survey. To practise general movements assessment (GMA), course certification is required. The self-learning exercise with the confirmed judgement FMs clips may be effective for improving the ability of FMs judgement.
