This study was carried out to investigate the relationship among the hand, eye, and ear lateralizations and the sense of rhythm of the athletes randomly selected from different sport branches. A total of 115 elite athletes including 72 males (62.6%) and 43 females (37.4%) whose mean age was 22.3 ± 2.4 years and who receive training at different…

Creativity is the ability to come up with new and original solutions to problems. It is characterized along a dipole spectrum, with the opposing ends defined as convergent and divergent thinking. Previous studies have provided evidence that various cognitive functions and insight into non-verbal problems can be enhanced using non-invasive brain…

The research paper presents an analysis of the interrelation between the lateral organisation profiles' indicators and self-regulation features. The existence of significant distinctions in the processes of self-regulation among respondents with different variants of lateral profiles of the interhemispheric asymmetry is proved, as well as the…

Viewing another person's hand actions enhances excitability in an observer's left and right primary motor (M1) cortex. We aimed to determine whether viewing communicative hand actions alters this bilateral sensorimotor resonance. Using single-pulse transcranial magnetic stimulation (TMS), we measured excitability in the left and right M1 while…

Objective: Findings about the association of left-handedness and ADHD are inconsistent. While abnormal brain laterality is reported in children with ADHD, it is unclear if hand preference is associated with ADHD, severity symptoms, age, gender, comorbid psychiatric problems, or parental characteristics. Method: Subjects were 520 boys and girls…

How "differences" between the two sides of the brain (or "laterality") relate to level of function are important components of theories of the origin and purpose of hemispheric asymmetry, although different measures show different relationships, and this heterogeneity makes discerning any underlying relationships a difficult…

In an Internet study unrelated to handedness, 134,317 female and 120,783 male participants answered a graded question as to which hand they preferred for writing. This allowed determination of hand preference patterns across 7 ethnic groups. Sex differences in left-handedness were found in 4 ethnic groups, favoring males, while no significant sex…

An experiment was conducted to examine whether perceptual information, specifically the shape of objects, is activated during semantic processing. Subjects judged whether a target word was related to a prime word. Prime-target pairs that were not associated, but whose referents had similar shapes (e.g. LADDER-RAILROAD) yielded longer ''no''…
