Description

Training method for improving generalization ability of autistic children
Technical Field
The invention belongs to the technical field of autism rehabilitation training, and particularly relates to a training method for improving the generalization ability of autism children.
Background
Child autism (called autism for short or autism) is a development disorder related to multiple aspects such as sensory perception, emotion, language, thinking, action and behavior and the like in early children, and is also the most common and typical development disorder in wide development disorders. At present, the number of intervention methods and training devices for autism is infinite, but most of the intervention methods and training devices can only improve some surface symptoms, and the intervention methods and the training devices are of little help for social communication and independent life of autism children. Autistic children often become trapped in a very specific or ad hoc form during learning and are difficult to adapt to changing environments because they lack the ability to generalize. Generalization is the ability to relate past experience to unknown experience, in short, after a response is linked to a stimulus-forming condition, the response will also be linked to other similar stimuli to form a condition to some extent. The university of Pittsburgh, NancyMinshew, professor in psychology and neurology, states that autistic individuals need to teach using a method that promotes generalization, rather than using a method that enhances their specificity. For example, in learning what is "dog" the use of a wide variety of dog examples, even a little more, includes all animals. Incorporating changes from the outset facilitates learning a broad concept, not a specific example. Generalization is very important in the auxiliary training process of autistic children, and the process that the trained children can use the same cognitive skill with different people, different objects or under different environments after receiving training is realized.
The learning efficiency is very low due to the fact that the autism students are weak in abstract thinking ability and logical thinking ability and poor in learning and generalization ability. When the subject learns a certain object or a certain knowledge point, the object or the knowledge point needs to be generalized in the life in time, so that the subject is promoted to be in connection with the life, the knowledge is applied to the life, and a knowledge cycle is formed. The learning knowledge is converted into the required social experience by means of generalization ability to raise one thing to the contrary three, and the clashing bypass is realized, so that the future life and learning are guided. The traditional teaching method and the traditional teaching equipment can not meet the requirements, so that in addition to a common teaching method, a Mixed Reality (MR) technology is brought into the intervention training of the cognitive generalization ability of the autistic children, virtual images are superposed on a real scene and used in a traditional teaching mode, teaching is matched in multiple directions and supplemented, an interactive teaching mode is formed, and the generalization ability of the autistic patients is emphatically trained more effectively and more conveniently.
