This is an article in a series that describes individual training modules within the RehaCom suite. The Responsiveness module (REA1) aims to improve reaction speed and accuracy to visual and acoustic stimuli.
Simple reaction tasks, simple choice, and multiple choice reaction tasks are used for training the client to react to certain stimuli as quickly and differentially as possible.
Indications for Responsiveness Training
Impairment of responsiveness can occur after cerebral lesions, disorders of selective attention performance, disturbances of visual and acoustic discrimination, cognition, and/or
behavioural performance. The module is less suitable for persons with severe ametropia (visual refractive error) or poor hearing. The module is suitable for persons aged 8 and up. This module may be useful in the early phase of rehabilitation and or with severe traumatic brain injury
Responsiveness is trained using simple reactions, simple choice, and multiple choice reactions with visual and/or acoustic stimuli.
The training contains either only visual (module 1) or visual and acoustic stimuli (module 2). After a stimulus has appeared, the client must press a particular button on the RehaCom panel
as fast as possible. During the acquisition phase, the client memorises the assignment of relevant stimuli to corresponding buttons. Reaction speed and accuracy are measured and evaluated.
Training material consists of more than 200 visual stimuli and 6 acoustic stimuli in 3 variations each. The therapist can also add visual and acoustic stimuli (pictures and sounds) through the integrated programme editor. The software has 20 levels of adaption.
The feedback provided to the client is both visual and acoustic.
The following options are available for visual feedback:
INCORRECT: The word "Incorrect" appears in a red field when the client presses an incorrect button. If the client does not react to stimuli after a certain period of time (2000 milliseconds[ms]), the phrase "Too Slow" appears.
INCORRECT+CORRECT: Depending on the quality of the reaction, the word "Correct" or "Incorrect" appears. If the client does not react to stimuli after a certain period of time (2000 ms), the phrase "Too Slow" appears.
Reaction times: The reaction times of the last 10 stimuli are displayed as a bar graph. If the reaction was incorrect, the bar appears in red. This feedback can be irritating and should be used only for high-performance patients. Correct reactions within the maximum reaction time are displayed in blue; reactions above the maximum reaction time are displayed in yellow. A red bar appears for instances when no reaction occurs within the two seconds that the stimulus is displayed or when a reaction is incorrect.
