Background: Deceptive movements occur when an actor seeks to fake, hide or delay kinematic information about their true movement outcomes. The purpose of deceptive movements is to impair the perception of opponents (the ‘observer’) to gain an advantage over them. We argue though that a lack of conceptual clarity has led to confusion about what deception is and in understanding the different approaches by which an actor can deceive their opponent. The aim of this article is to outline a conceptual framework for understanding deceptive movements in sport. Main body: Adopting Interpersonal Deception Theory from the field of communication, we define deception as when an actor deliberately alters their actions in an attempt to impair the ability of an observer to anticipate their true action outcomes. Further, deception can be achieved either by what we define as deceit, the act of providing false information, or disguise, the act of concealing the action outcome. Skilled athletes often have actions that are difficult to anticipate, but an action is only classified as containing deception if the actor has explicit intent to deceive an observer. Having outlined the conceptual framework, we then review existing empirical findings on the skilled perception of deceptive movements considering the framework. This approach includes a critical evaluation of the mechanisms known to facilitate the perceptual ability to prevent being deceived, including a consideration of visual search strategies, confidence, the contribution of visual and motor experiences, and the influence of response biases and action capabilities on perceptual performance. Conclusion: The distinction between deceit and disguise particularly helps to show that most research has examined deceit, with little known about how an actor can more effectively disguise their action, or about how an observer can improve their ability to anticipate the outcome of disguised actions. The insights help to identify fruitful areas for future research and outline implications for skill acquisition and performance enhancement.

In cognitive science, creative ideas are defined as original and feasible solutions in response to problems. A common proposal is that creative ideas are generated across dedicated cognitive pathways. Only after creative ideas have emerged, they can be enacted to solve the problem. We present an alternative viewpoint, based upon the dynamic systems approach to perception and action, that creative solutions emerge in the act rather than before. Creative actions, thus, are as much a product of individual constraints as they are of the task and environment constraints. Accordingly, we understand creative motor actions as functional movement patterns that are new to the individual and/or group and adapted to satisfy the constraints on the motor problem at hand. We argue that creative motor actions are promoted by practice interventions that promote exploration by manipulating constraints. Exploration enhances variability of functional movement patterns in terms of either coordination or control solutions. At both levels, creative motor actions can emerge from finding new and degenerate adaptive motor solutions. Generally speaking, we anticipate that in most cases, when exposed to variation in constraints, people are not looking for creative motor actions, but discover them while doing an effort to satisfy constraints. For future research, this paper achieves two important aspects: it delineates how adaptive (movement) variability is at the heart of (motor) creativity, and it sets out methodologies toward stimulating adaptive variability.

Everyone has the right to participate in society to the best of their ability. This right also applies to people with a visual impairment, in combination with a severe or profound intellectual and possibly motor disability (VISPIMD). However, due to their limitations, for their participation these people are often highly dependent on those around them, such as family members andhealthcare professionals. They determine how people with VISPIMD participate and to what extent. To optimize this support, they must have a good understanding of what people with disabilities can still do with their remaining vision.It is currently difficult to gain insight into the visual abilities of people with disabilities, especially those with VISPIMD. As a professional said, "Everything we can think of or develop to assess the functional vision of this vulnerable group will help improve our understanding and thus our ability to support them. Now, we are more or less guessing about what they can see.Moreover, what little we know about their vision is hard to communicate to other professionals”. Therefore, there is a need for methods that can provide insight into the functional vision of people with VISPIMD, in order to predict their options in daily life situations. This is crucial knowledge to ensure that these people can participate in society to their fullest extent.What makes it so difficult to get this insight at the moment? Visual impairments can be caused by a range of eye or brain disorders and can manifest in various ways. While we understand fairly well how low vision affects a person's abilities on relatively simple visual tasks, it is much more difficult to predict this in more complex dynamic everyday situations such asfinding your way or moving around during daily activities. This is because, among other things, conventional ophthalmic tests provide little information about what people can do with their remaining vision in everyday life (i.e., their functional vision).An additional problem in assessing vision in people with intellectual disabilities is that many conventional tests are difficult to perform or are too fatiguing, resulting in either no or the wrong information. In addition to their visual impairment, there is also a very serious intellectual disability (possibly combined with a motor impairment), which makes it even more complex to assesstheir functional vision. Due to the interplay between their visual, intellectual, and motor disabilities, it is almost impossible to determine whether persons are unable to perform an activity because they do not see it, do not notice it, do not understand it, cannot communicate about it, or are not able to move their head towards the stimulus due to motor disabilities.Although an expert professional can make a reasonable estimate of the functional possibilities through long-term and careful observation, the time and correct measurement data are usually lacking to find out the required information. So far, it is insufficiently clear what people with VZEVMB provoke to see and what they see exactly.Our goal with this project is to improve the understanding of the visual capabilities of people with VISPIMD. This then makes it possible to also improve the support for participation of the target group. We want to achieve this goal by developing and, in pilot form, testing a new combination of measurement and analysis methods - primarily based on eye movement registration -to determine the functional vision of people with VISPIMD. Our goal is to systematically determine what someone is responding to (“what”), where it may be (“where”), and how much time that response will take (“when”). When developing methods, we take the possibilities and preferences of the person in question as a starting point in relation to the technological possibilities.Because existing technological methods were originally developed for a different purpose, this partly requires adaptation to the possibilities of the target group.The concrete end product of our pilot will be a manual with an overview of available technological methods (as well as the methods themselves) for assessing functional vision, linked to the specific characteristics of the target group in the cognitive, motor area: 'Given that a client has this (estimated) combination of limitations (cognitive, motor and attention, time in whichsomeone can concentrate), the order of assessments is as follows:' followed by a description of the methods. We will also report on our findings in a workshop for professionals, a Dutch-language article and at least two scientific articles. This project is executed in the line: “I am seen; with all my strengths and limitations”. During the project, we closely collaborate with relevant stakeholders, i.e. the professionals with specific expertise working with the target group, family members of the persons with VISPIMD, and persons experiencing a visual impairment (‘experience experts’).
Door ontwikkelingen in de zorg leven meer mensen die intensieve ondersteuning nodig hebben zelfstandig of begeleid thuis. Tegelijkertijd stijgt het aantal mensen explosief dat het zonder professionele begeleiding thuis niet zelfstandig redt. Vooral voor mensen met licht verstandelijke beperking (LVB), is (begeleid) zelfstandig wonen en meedoen in de maatschappij niet makkelijk. Dit komt door de verstandelijke beperkingen én juist ook bijkomende problematiek. Effectieve behandeling van deze bijkomende problematiek is noodzakelijk. Vaktherapie is een behandelvorm die naadloos aansluit bij de aandachtspunten voor effectieve interventies bij deze doelgroep en wordt intramuraal al jarenlang als een waardevolle aanvulling gezien op behandelvormen met een meer verbale insteek. Echter, vaktherapie wordt nog nauwelijks in de leefomgeving van mensen met LVB aangeboden. Een ontwikkeling in deze richting is momenteel wel gaande. Vaktherapeuten werken vaker samen met FACT-LVB teams volgens een ontwikkeld samenwerkingskader. Dit kader blijkt niet toepasbaar voor andere contexten in de leefomgeving, waar structuur in samenwerking vaak niet aanwezig is en ook samenwerking met informele hulpverleners nodig is. Een aangepast samenwerkingskader om structurele samenwerking te realiseren tussen vaktherapeuten en (in)formele hulpverleners is essentieel. Evenals nader inzicht in welke vaktherapeutische interventies in de leefomgeving werken. In dit praktijkgericht onderzoek wordt het eerder ontwikkeld samenwerkingskader met focusgroepen doorontwikkeld en toepasbaar gemaakt voor meerdere contexten in de leefomgeving (deelonderzoek 1). De toepassing van dit kader wordt in een procesevaluatie geëvalueerd (deelonderzoek 2). Middels gestapeld N=1 onderzoek wordt onderzocht welke vaktherapeutische interventies in de leefomgeving werken bij welke indicaties (deelonderzoek 3). De inzichten worden verwerkt tot een breed toepasbaar samenwerkingskader, een indicatiemodel voor vaktherapeutische behandeling in de leefomgeving en een methode om vaktherapeutisch handelen te blijven evalueren.
Het TOP-programma is een landelijke evidence-based interventie voor zeer vroeggeboren kinderen (<32 weken zwangerschap) en hun ouders, gericht op het verbeteren van de ouder-kind interactie en de ontwikkeling van het te vroeg geboren kind. Goede informatievoorziening over de ontwikkeling en gezondheid van het te vroeg geboren kind hangt samen met betere ontwikkelingsuitkomsten. Daarom is kennisoverdracht één van de strategieën van het TOP-programma. Deze kennisoverdracht vindt plaats tijdens 12 huisbezoeken. Uit vooronderzoek kwam naar voren dat ouders en kinderfysiotherapeuten (MKB) behoefte hebben aan aanvullende informatievoorziening over slaap, ontwikkeling en voeding. Dit geldt in het bijzonder voor de groep kwetsbare ouders met beperkte gezondheidsvaardigheden, die nu onvoldoende profiteren van de interventie omdat de professionals er niet in slagen de kennis over te dragen. Verder wordt de doelgroep matig vroeggeboren kinderen (32-34 weken zwangerschap) niet behandeld met het TOP programma terwijl de problematiek veelal overeenkomt met de zeer vroeggeboren kinderen. Door de MKB professionals wordt een online informatiemodule (E-TOP) voor het vergroten van kennis en inzicht van ouders over de gevolgen van vroeggeboorte en begeleiding van hun kind als veelbelovend gezien. TOP-therapeuten zien kansen om met deze module een bredere doelgroep te bereiken. De onderzoeksvraag in dit project luidt: “Hoe kunnen kinderfysiotherapeuten, aanvullend op het TOP programma, op een toegankelijke en begrijpelijke manier meer kennis en inzichten overdragen aan ouders over de ontwikkeling van hun zeer en matig vroeggeboren kind?”. In de eerste fase van dit project wordt de online toepassing in co-creatie met de MKB partners, ouders en andere betrokkenen ontwikkeld. In creatieve workshops en focusgroepen, o.a. ouders met beperkte gezondheidsvaardigheden, worden de functionaliteiten, content en tekortkomingen van de online toepassing onderzocht. In de tweede fase wordt het ontwikkelde programma in een haalbaarheidsstudie (n=80) onderzocht op toepasbaarheid, bruikbaarheid en tevredenheid. Doorwerking naar werkveld en onderwijs zal gedurende en na het project plaatsvinden.
