Interestingly, these past studies, just like many others, differed from each other in how handedness was measured and how participants were categorised 6 some of them simply asked people what their hand preference
was in general.
Right and left handedness defined: A multivariate approach using hand preference
and hand performance measures.
Yeo RA, Gangstad SW, Daniel WF (1993) Hand preference
and developmental instability.
In general, it can be stated that the trends in left eye and hand preference
in the three studies are similar.
Thus, according to this point of view, it would appear that hand preference
cannot always be predicted in terms of which side of the brain is the dominant one.
Moreover, Teng, Lee, Yang, and Chang (1976) established that social pressure was useful for eating and writing with right-hand but did not have a great influence on hand preference
in other tasks.
The same subjects, after 10-12 years of age (after birth), showed a remarkable correlation of hand preference
with intrauterine hand preference
Functional brain asymmetry and individual differences in hand preference
in early ontogeny.
Keki Buku is in only his second season hurdling and could put past disappointments behind him with added maturity, but there is enough in that record to help hand preference
to Diamond Brook.
The scale is designed to measure hand preference
on a variety of physical activities (i.
Either because of the social sanctions, genetic pool, or developmental vulnerabilities, the hand preference
pattern, especially left-handedness, in Indians is different as compared to the western population.
If equal responses occurred in Part 1 (2 cases), then the side opposite the hand preference
was designated in Part 2.
Still other types of biological causes for left hand preference
have been proposed, including those that conceive of underlying constitutional patterns for lateralization, as well as ones emphasizing transmission through single genes, abnormalities of neuronal migration, problems in the intrauterine hormonal environment, and/or a disorder of the immune system (Bishop, 1990; Geschwind & Behan, 1982; Levy & Nagylaki, 1972).
This paper describes hand preference
in healthy samples that may be used for comparison with clinical or other selected groups.
The investigators identified laterality based on hand preference
for writing and foot preference for kicking a ball, which was determined at age l0 in the British Cohort Study and at age 7 in the National Child Development Study.
