Ten healthy volunteers (mean ± SD age: 30.1 ± 5.4 years) with no history of neurological disorders were recruited for the study. To avoid variability in primary cortex activation patterns, only participants with an Edinburgh Handedness Inventory (Oldfield 1971) score greater than 0.7 (right hand dominance) were included. None of them had undergone any prior BCI or neurofeedback training. All participants gave written informed consent for the study.
Autism Spectrum Disorder

In this study, the incidences of mixed handedness and ambiguous handedness were significantly higher in autistic children compared to typically developing children. These findings are in agreement with previous observations on the disturbances in hand preference in ASD [8, 10, 36, 50, 110]. Soper et al. [110] reported a dramatic shift away from right-handedness in lower functioning autistic subjects due to an increased frequency of two phenotypes, manifesting left-handedness and ambiguous handedness, as the ambiguously handed were found to exhibit much lower intellectual scores. Hauck and Dewey [50] found that the lack of a definite hand preference in children with ASD was linked with poorer performances on motor, language and cognitive tasks. Escalante-Mead et al. [36] compared high-functioning autistic individuals with and without early language impairment and healthy individuals on an assessment of manual preference by the Edinburgh Handedness Inventory and found an increased rate of left-handedness among autistic individuals with a history of early language disturbance, and a higher incidence of mixed-handedness in all autistic individuals with and without early language impairment. In a recent study, Scharoun and Bryden [106] assessed three measures of handedness (Waterloo Handedness Questionnaire, Annett pegboard and WatHand Cabinet Test) in two repeated sessions and reported that although no differences were revealed between children with ASD and normal children, children with ASD demonstrated variable performance of the Annett pegboard, providing partial support for literature describing autistic individuals as having a weak hand preference.

Seven patients with subacute post-stroke hemiplegia (five men and two women; mean age, 60.3 ± 11.6 years) and 22 able-bodied young adults (control group; 11 men and 11 women; mean age, 21.7 ± 1.35 years; height, 166.2 ± 7.09 cm; body weight, 59.1 ± 11.13 kg; body mass index, 21.3 ± 3.19) participated in this study. All patients in the post-stroke period were right-handers, had a first-ever unilateral stroke, and did not have any other neurological or musculoskeletal disorders. The handedness in individuals in the post-stroke period was confirmed verbally. The handedness in able-bodied young adults was assessed using the Edinburgh Handedness Inventory (20). No participants among the able-bodied young adults had any cardiovascular, orthopedic, neurological, musculoskeletal (including the fatigue of an arm), or vestibular diseases, or visual and hearing impairments, dementia, or dermatosis. The Fugl–Meyer Assessment scale (21), for the motor function of the upper extremities; the functional independence measure; and handgrip force were evaluated to identify the characteristics of the patients after stroke (Table 1). The score on the Modified Ashworth Scale 18 was ≤2 in all patients with stroke. The Research Ethics Committee of the National Institute of Information and Communications Technology and the Ethics Committee of the Nittazuka Medical Welfare Center (No. 30–50) approved this study. All participants signed an informed consent form.

Lastly, Handedness was assessed from the Edinburgh Handedness Inventory – Short Form, which has demonstrated evidence of validity [41]. Participants were asked to indicate their preferences in the use of hands in the following activities or objects: writing, throwing, toothbrush, and spoon use. Response options included: always right, usually right, both equally, usually left, and always left. For each item, the following scores were given: 100 (always right), 50 (usually right), 0 (both equally), −50 (usually left), and −100 (always left). The Laterality Quotient was calculated by summing these four scores and then dividing it by 4. Handedness classification was determined from the following Laterality Quotient scores: −100 to −61 (left-handed), −60 to 60 (mix-handed), and 61 to 100 (right-handed).
Sleep Behaviors and Handedness in Gifted and Non-Gifted Children

To assess handedness status as an indication of laterality and its potential effects, all children completed the Edinburgh Handedness Inventory (EHI) (Oldfield, 1971). The EHI consists of 10 items representative of hand preference (writing, drawing, throwing, using scissors, holding a toothbrush, handling a knife without a fork, using a spoon, the upperhand when using a broom, striking a match, and opening the lid of a box). One item not on the standard inventory was also added: using a computer mouse. In order to capture a broader picture of individual laterality, three additional questions on foot (Which foot do you prefer to kick with?), eye (Which eye do you use when you only use one?), and ear (Which ear do you put a phone to?) preferences were added.
