The Overview of Dr. NeuronowskiIntroductory games to familiarise patients with the training, types of games, and sounds usedAuditory perceptionReaction speedResponse inhibitionAlertnessAuditory perception of nonverbal stimuliShort-term nonverbal auditory memorySelective attentionSustained attentionMillisecond TIP—processing of short sounds presenting in rapid successionNonverbal and verbal auditory short-term memory—memorising sequences of various lengthMillisecond TIP—processing of rapidly changing soundsPhonemic hearing based on phoneme change detection in syllables or in words differing in single consonant soundsVerbal auditory short-term memory based on artificially slowed verbal stimuliMillisecond and multisecond TIP—estimation of time intervalsDelay of responsesResponse inhibitionPhonemic hearing based on artificially modified voice onset timeMillisecond TIP—voice onset time perceptionThe task difficulty in particular games was modified by: number, length, and presentation rate of verbal and nonverbal stimuli, the rate of modified speech, various inter-stimulus intervals in sequentially presented stimuli, application of distractors, and time limits for the patient’s responses.The The protocols of both the experimental and control trainings involved 24 individual sessions of 45 min each, 3 times a week. All exercises were performed on a tablet. The training sessions were conducted with the assistance of a therapist, whose role was to monitor the patient’s performance and to provide technical assistance in handling the tablet. In both experimental and control trainings, the task difficulty in particular games changed adaptively on the basis of the actual level of the patient’s performance.
