The overhand throw is a complex whole-body motor skill that is fundamental to many sports and activities. When throwing properly, the momentum generated to complete the movement begins in the lower body and transfers through the trunk to the throwing arm. This proof-of-concept study's primary purpose was to evaluate the impact of the nonthrowing…

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…

In alphabetic languages, print consistently elicits enhanced, left-lateralized N170 responses in the event-related potential compared to control stimuli. In the current study, we adopted a cross-linguistic design to investigate N170 tuning to logographic Chinese and to "pinyin," an auxiliary phonetic system in Chinese. The results…

Rapidly changing environments in day-to-day activities, enriched with stimuli competing for attention, require a cognitive control mechanism to select relevant stimuli, ignore irrelevant stimuli, and shift attention between alternative features of the environment. Such attentional orchestration is essential to the acquisition of reading skills. In…

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…

We investigated the presence and the characteristics of the Simon effect for onset and offset targets when these stimuli are randomly intermixed. In Experiment 1, two possible target locations were occupied by an occluder. On onset trials, a target appeared above an occluder, while on offset trials one of the occluders disappeared, revealing the…

To examine the effect of long lasting practice on pedal behavior in sport, we compared experienced adult soccer players and nonsoccer players on leg preference in motor tasks requiring general mobilization, soccer related mobilization, and body balance stabilization. We also evaluated performance asymmetry between the right and left legs in static…

This study examined the differences in processing between regular and dyslexic readers in a lexical decision task in different visual field presentations (left, right, and center). The research utilized behavioral measures that provide information on accuracy and reaction time and electro-physiological measures that permit the examination of brain…

This study explored the relationship between handedness and interest in night-sky watching. University students (N= 128) completed the Edinburgh Handedness Inventory (Oldfield, 1971) and the Noctcaelador Inventory (Kelly, 2004). The findings indicated that mixed-handed participants scored highest on noctcaelador relative to those classified as…

We investigated the differences in mechanical power flow in early and late practice stages during a cyclic movement consisting of upper arm circumduction to clarify the change in mechanical energy use with skill acquisition. Seven participants practiced the task every other day until their joint angular movements conformed to those of an expert.…

Examined relationship between handedness and preferred ear for telephoning in 140 college students. Increased degree of sinistrality was associated with increased tendency to use left ear for telephoning. Found tendency to pick up telephone receiver with preferred hand and hold earpiece to ipsilateral ear. Results may relate to reports of reduced…

Reports two studies which examined the relationship among (1) the ability to determine horizontality, (2) a general test of spatial abilities, and (3) hemispheric activation as measured by lateral eye movements. (JMB)

Numerous areas associated with brain dominance have been researched since Bogen and Sperry's work with split-brain patients in the 1960s, but only slight attention has been given to the connection between brain dominance and personality. No study appears in the literature seeking to understand optimal mental health as defined by Maslow's…

Spatial and sequential tasks performed both independently and jointly were compared for 40 undergraduates grouped by sex and dominant hand. When both tasks were performed simutaneously, there was a significant advantage for right-handers and a slight advantage for males. This was attributed to hemispheric interference left-handers experienced.…
