Serious gaming can be used in?
physical as well as cognitive rehabilitation
Van der Kuil et al. (2018) aimed to change patients’ navigation strategy by the use of navigation exercises and psycho-education. The serious game is a home-based rehabilitation that does not require supervision. Their study investigated three core principles of the serious game:
- Interaction in 3D environments: the interaction should be unrestricted and realistic
- Instruction modality: patients need to understand the concepts and skills underlying the training
- Feedback timing: the type, amount and timing of feedback influence the motivation and learning efficacy
of the patient.
What is the main issue with developing a standardized treatment for navigation impairments?
The main issue with developing a standardized treatment for navigation impairments is that complaints are diverse and the human navigation system contains many parts of the brain, making it highly vulnerable to brain damage.
What are the two types of reference frames used in navigation training?
An egocentric reference frame (in relation to one’s own body) and an allocentric reference frame (irrespective of one’s own position).
How does the study by Van der Kuil et al. (2020) propose to improve navigation ability in patients with navigation impairments?
The study proposes to improve navigation ability in patients with navigation impairments by using home-based navigation rehabilitation training that is focused on compensatory navigation strategies, treating a broad range of navigation complaints, covering multiple spatial domains, and including face-to-face therapy and (unsupervised) training.
What are the common problems caused by navigation impairments?
Navigation impairments lead to reduced mobility, autonomy and spatial anxiety among patients.
What is small scale space?
Everything that fits on a table top and that you can interact with without having to move your body (e.g., a rubrics cube)
What is large scale space?
When you have to walk through a real maze (so not digitally).
Problems in large scale hold very little/ great relations to whether they have a small scale problem.
Little
What are the 3 types of very basic spatial behavior?
- Route following; finding the shortest route and keep using this.
- Piloting; exploring the environment. Experiment:
- Dead reckoning: when you take a left turn and walk a bit further, your body will memorize your starting point. Your body will calculate the quickest way back to the starting point.
Navigation starts with input = …., then we process this input = …. and that results in spatial representations of space.
Spatial cues, computational mechanisms
Spatial cues can be ….. (e.g., landmarks, maps) and ….. (e.g., vestibular cues, optic/auditory/tactile flow and proprioceptive feedback).
Environmental, self-motion
Computational mechanisms consist of?
Spatial computations that are being made (e.g., computing directions and distances and imagining shifts in spatial perspective, ego perspective) and of executive processes (e.g., route planning or selection and handling uncertainty or conflicts, novelty detection).
Spatial representations can be online or offline. What do they mean?
We use online representations while in the environment. Offline representations are made up from memories of your online representations
What is an important early marker of Alzheimer’s disease?
Navigation problems/ spatial performance
