Handedness, Time Use and Early Childhood Development We test if there is a differential in early child development by handedness, using a comprehensive range of measures covering, learning, social, cognitive and language skills, evaluated by both interviewer conducted tests and teacher assessments. We find robust evidence that left-handed children do significantly worse in nearly all measures o...

Handedness, as a potentially influencing, nonpathologic factor, has not been investigated in relation to transient evoked otoacoustic emissions (TEOAEs). The present study aimed to examine the effects of handedness on the TEOAE spectrum in entry-level schoolchildren, with attention also to possible ear asymmetry. A total of 228 subjects (114 males, 114 females, mean age = 6.3 years) were tested...

Handedness is not a unidimensional trait but rather part of a multifactorial system best described as one of the aspects comprising human laterality of the whole body and including associated neural mechanisms. In this review, different methods for assessing and classifying handedness are examined and three major models – genetic, pathological and environmental factors – are explored as a possi...

It has been suggested that twinning may influence handedness through the effects of birth order, intra-uterine crowding and mirror imaging. The influence of these effects on handedness (for writing and throwing) was examined in 3657 Monozygotic (MZ) and 3762 Dizygotic (DZ) twin pairs (born 1893-1992). Maximum likelihood analyses revealed no effects of birth order on the incidence of left-handed...

Reversible handedness inversion is achieved in self-organized helical superstructures using a visible-light-driven macrocyclic chiral switch, as reported by Quan Li and co-workers their Research Article (e202216600). Green blue light can drive the reversible switching between left- right-handedness via cis/trans photoisomerization of azobenzene within cyclic molecular switch.

Handedness is a performance-influencing factor in many competitive sports. In female team handball, psychological factors such as motivation have been connected to handedness. It should be researched whether this also the case wheel gymnastics and related performance or For purpose, 203 German gymnasts were studied. There are significant differences motivational aspects between of different han...

Although hand grip strength is critical to the daily lives of humans and our arboreal great ape relatives, human has changed in form function throughout evolution due terrestrial bipedalism, tool use, directional asymmetry (DA) such as handedness. Here we investigate how interact modern gain an insight into evolutionary past. We measured a heterogeneous, cross-sectional sample participants (n =...

The objective of this study was to assess whether smoking habits can explain the decline in left-handedness prevalence with age. Subjects participating in a population-based survey (n = 3,071) in Geneva, Switzerland, completed a questionnaire on innate hand preference, current hand preference for writing and smoking habits. The prevalence of innate left-handedness in the Geneva population was 9...

The apparent handedness of an EM-tomography reconstruction depends on a number of conventions and can be confused in many ways. As the number of different hardware and software combinations being used for electron tomography continue to climb, and the reconstructions being produced reach higher and higher resolutions, the need to verify the hand of the results has increased. Here we enumerate v...
