The human parietal cortex exhibits a preference to contralaterally presented visual stimuli (i.e., laterality) as well as an asymmetry between the two hemispheres with the left parietal cortex showing greater laterality than the right. Using visual short-term memory and perceptual tasks and varying target location predictability, this study examined whether hemispheric laterality and asymmetry ...

REASON FOR PERFORMING STUDY Foot stance in grazing significantly influences hoof conformation and development from foal to yearling age. OBJECTIVES To conduct a longitudinal study to establish if the relationship between motor laterality and uneven front feet persisted in 3-year-old horses at the time of studbook selection and to investigate if such laterality and unevenness might influence t...

OBJECTIVE To investigate whether patterns of dysphagia and swallowing laterality differ according to the location of brain lesions in patients with stroke. METHODS Patients with stroke >20 years of age were enrolled in this study. A videofluoroscopic swallowing study (VFSS) including the anterior-posterior view was used to assess swallowing. Patterns of swallowing were classified into three t...

The satellite symposium on 'Making and breaking the left-right axis: implications of laterality in development and disease' was held in June 2013 in conjunction with the 17th International Society for Developmental Biology meeting in Cancún, Mexico. As we summarize here, leaders in the field gathered at the symposium to discuss recent advances in understanding how left-right asymmetry is genera...

Much of contemporary laterality research has been motivated by a need to increase the accuracy with which individuals can be classified as left- or right-hemisphere dominant for speech and language. Efforts to improve the classification accuracy of laterality methods have led not only to the refinement of laterality methods but also to the discovery of some of the mechanisms that contribute to ...

This investigation examined the premise derived from recent reports, that children who are consistent right-handers are better coordinated than their left- and mixed-sided (inconsistent) peers. The observation of limb laterality was extended to include footedness. Two samples of children (N = 273) (foot laterality/hand laterality), matched for age and sex, were assessed for motor proficiency an...

This paper estimates the relationship between handedness and social adjustment in children. In addition to binary measures of hand preference, we also use a continuous measure of relative hand skill. Outcomes at ages 7, 11 and 16 are studied. The data used is the British 1958 Birth. Using a partially linear semi-parametric regression estimator, it is shown that non-right-handedness (as hand pre...

In this study, the unrehearsed performance of music, known as 'sight reading', is used as a model to examine the influence of motoric laterality on highly challenging musical performance skills. As expertise research has shown, differences in this skill can be partially explained by factors such as accumulated practise and an early start to training. However, up until now, neurobiological facto...

Ocklenburg et al. (2020, Laterality 2020: Entering the next decade. Laterality) provided field of laterality research with a stimulating perspective for coming decade, based on current state art in both animal and human research. Although this is paper takes many different approaches into account, we emphasize that eco-evolutionary approach needs more attention. This concerns question why organ...

A model for the subjective lateral position of 500-Hz tones is presented and compared with experimental lateralization data. Previous papers in this series have explicitly described the auditory-nerve response to these stimuli and proposed a binaural displayer that interaurally compares the auditory-nerve firing times. The outputs of the displayer are postulated to represent the only informatio...
