Abstract:

In this study, to test an inference from the 1991 Previc hypothesis that right-handers have a right-ear advantage, the durations of hearing for the right and left ears were compared for 81 right- and 45 left-handed high school students. In the present study, right-handedness was associated with a right-ear advantage and left-handedness was associated with a left-ear advantage. In addition, there was a significant positive correlation between the durations of hearing for the right and left ears and the scores for right-handedness for right-handed subjects. The durations of hearing for the right

Abstract:

This cross-sectional, analytical type of study was performed in Department of Anatomy, Dhaka Medical College, Bangladesh, from July 2016 to June 2017 on 52 right hander male and 52 right hander female, 40 left hander male and 34 left hander female Bangladeshi medical students. Convenient purposive sampling technique was adopted. History of any injury of upper limb was excluded to construct standard measurement. Handedness of each medical student was determined by the Edinburgh handedness inventory. Hand breadth and hand length was measured with the help of vernier caliper. Paired and unpaired

Abstract:

Handedness in plant growth may be most familiar to us when we think of tendrils or twining plants, which generally form consistent right– or left–handed helices as they climb. The petals of several species are sometimes arranged like fan blades that twist in the same direction. Another less conspicuous example is ‘circumnutation’, the oscillating growth of axial organs, which alternates between a clockwise and an anti–clockwise direction. To unravel molecular components and cellular determinants of handedness, we screened Arabidopsis thaliana seedlings for helical growth mutants with fixed han

Abstract:

Left-handers have been persecuted by right-handers for millennia. This right bias is evident cross-culturally, linguistically (right is literally and figuratively ‘right’, with lefties being described as ‘gauche’, ‘sinister’ and ‘cack-handed’), and environmentally (e.g., equipment design, including power tools, ticket machines, and lecture-room desks). Despite this, the proportion of left-handers has remained constant at approximately 10% of the hominid population, implying that though there are costs associated with left-handedness (if there were not, the proportions of left- and right-hander

Abstract:

Behavioural asymmetries displayed by individuals, such as hand preference and foot preference, tend to be lateralized in the same direction (left or right). This may be because their co-ordination conveys functional benefits for a variety of motor behaviours. To explore the potential functional relationship between key motor asymmetries, we examined whether footedness, handedness, or throwing arm was the strongest predictor of eyedness. Behavioural asymmetries were measured by self-report in 578 left-handed and 612 right-handed individuals. Cluster analysis of the asymmetries revealed four han

Abstract:

Lateralization is one of the central questions in neurology, neuropsychology, and other related scientific disciplines. There has been very little change in the proportion of left-handers since the Upper Paleolithic Age about 10,000 years ago and it is estimated to be around 10%. As the history of human thinking has developed from superstition to science, the explanation of left-handedness transformed from ?devil?s work? to neurological specificity. This paper presents this very interesting historical change by analyzing the data on left-handedness and the attitudes towards it in human societi

Abstract:

Recent development of neuroimaging techniques has opened new possibilities for the study of the relation between handedness and the brain functional architecture. Here we report fMRI measurements of dominant and non-dominant hand movement representation in 12 right-handed subjects using block design. We measured possible asymmetry in the total volume of activated neural tissue in the two hemispheres during simple and complex finger movements performed either with the right hand or with the left hand. Simple movements consisted in contraction/extension of the index finger and complex movements

Object. The authors investigated brain strategies associated with hand use in an attempt to clarify genetic and nongenetic factors influencing handedness by using high-field functional magnetic resonance imaging. Methods. Three groups of patients were studied. The first two groups comprised individuals in whom handedness developed spontaneously (right-handed and left-handed groups). The third group comprised individuals who were coercively trained to use the right hand and developed mixed handedness, referred to here as trained ambidexterity. All trained ambidextrous volunteers were certain th

Abstract:

Lateralisation associates the extremities and senses of one side of the body, which are connected by afferent and efferent pathways, with the primary motor and sensory areas of the hemisphere on the opposite side. Dominant laterality denotes the appearance of a dominant extremity or sense in the performance of complex psychomotor activities. Laterality is manifested both as right-handedness or left-handedness, which are functionally equivalent and symmetrical in the performance of activities. Right-handedness is significantly more common than left-handedness. Genetic theory is most widely acce

Abstract:

A survey of handedness in Kwakiutl Indian totem and house poles found 56% bihandedness, 24% left-handedness, and 20% right-handedness. These findings are in marked contrast to other research findings on artforms, which show about 90% right-handedness. In the previous studies no systematic variation in the incidence of right-handedness was found across time eras, cultures, or geographic location. This apparent consistency was interpreted as supporting an hypothesis that right-handedness is universal and physiological. However, the present authors' findings with regard to Kwakiutl handedness cle
