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.

Hand preference was determined by asking participants to fill out the Edinburgh Handedness Inventory Form (EHI; Oldfield, 1971). This validated questionnaire provides a measure of handedness by testing the hand used during 10 activities of daily living (e.g., writing; throwing; using a toothbrush; and using a spoon). For each of the 10 activities, participants rated whether they use their right or left hand for that activity on a 5-point scale from always right to always left. According to the questionnaire guidelines, we scored always right as 2, always left as 0, with increments of 0.5 between, meaning mixed-handedness scored 1. Participants whose average score across all 10 tasks was greater than one were classified as right-hand preferred, those whose score was below one were classified as left-hand preferred, and a score equal to one were classified as mixed preference. We classified golf stance by the type of clubs used (right-hand or left-hand). The clubs used are dictated by the stance. Asking about club type is a more accessible question for golfers that removes the need to describe shoulder and hand position (i.e., you cannot hit in a right-handed club with a left-handed stance).

An experiment was conducted involving repetitive training of a basic psychomotor task using a contemporary haptic device. Twenty-four right-handed individuals (9 females, 15 males; mean age: 25.45 yrs.; SD = 8.6 yrs.) without prior experience with the haptic device (a Novint Falcon) were randomly selected from a local population and participated in the study. North Carolina State University Institutional Review Board approved the experiment protocol and all participants signed an informed consent form before any experimental procedure. The handedness of participants was assessed with the Edinburgh Handedness Inventory (Oldfield 1971) in order to ensure no ambidexterity. All participants were strongly right-handed with an average Edinburgh score of 94.45 (SD = 8.23). Participants were also screened for no current or chronic back, shoulder, neck or wrist pain. All participants were compensated at a rate of $15 per hour for their time. They also received an additional $15 if their task performance was among the ‘top 3’ for all participants. The bonus was intended to further motivate performance.
Moderate-to-vigorous physical activity, executive functions and prefrontal brain oxygenation in children: A functional near-infrared spectroscopy study

Fifty-five participants (26 females, 29 males) were recruited from 2 academic high schools in the greater area of Leipzig, Germany. Eligible students had to have right-hand dominance as controlled by the Edinburgh Handedness Inventory (Oldfield, 1971) and to be 10–11 years of age. Exclusion criteria were regular drug intake and prevalence of chronic or acute diseases, which could possibly restrict physical activity during everyday life. Study participants wore accelerometers for 7 days and completed 3 different executive function tasks. fNIRS was used to measure the blood oxygenation in the PFC during these tasks. Additionally, the self-report version of the strengths and difficulties questionnaire (SDQ; Goodman, Meltzer, & Bailey, 1998) was administered to assess the psychopathology of the study participants. Written assent and informed consent were provided by the children and their legal guardians, respectively. All procedures were in line with the Declaration of Helsinki and ethical approval was granted by the local ethics committee.
